Computer hardware Essays - Computer Hardware, Electronics Computer hardware Computer hardware (usually simply called hardware when a computing context is implicit) is the collection of physical elements that constitutes a computer system. Computer hardware is the physical parts or components of a computer, such as the monitor, mouse,keyboard, computer data storage, hard disk drive (HDD), graphic cards, sound cards, memory, motherboard, and so on, all of which are physical objects that are tangible.[1] In contrast, software is instructions that can be stored and run by hardware. Software is any set of machine-readable instructions that directs a computer's processor to perform specific operations. A combination of hardware and software forms a usable computing system. Von Neumann architecture. Von Neumann architecture scheme. The template for all modern computers is the Von Neumann architecture, detailed in a 1945 paper by Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of anarithmetic logic unit and processor registers, a control unit containing an instruction register and program counter, a memory to store both data and instructions, external mass storage, and input and output mechanisms.[3] The meaning of the term has evolved to mean astored-program computer in which an instruction fetch and a data operation cannot occur at the same time because they share a commonbus. This is referred to as the Von Neumann bottleneck and often limits the performance of the system.[4] Different systems. There are a number of different types of computer system in use today. Personal computer. Hardware of a modern personal computer: 1. Monitor 2.Motherboard 3.CPU 4. RAM 5.Expansion cards6. Power supply 7.Optical disc drive8. Hard disk drive9. Keyboard 10.Mouse. Inside a custom-built computer: power supply at the bottom has its own cooling fan. The personal computer, also known as the PC, is one of the most common types of computer due to its versatility and relatively low price.Laptops are generally very similar, although may use lower-power or reduced size components. Case. The computer case is a plastic or metal enclosure that houses most of the components. Those found on desktop computers are usually small enough to fit under a desk, however in recent years more compact designs have become more common place, such as the all-in-one style designs from Apple, namely the iMac. Though a case can basically be big or small, what matters more is which form factor of motherboard its designed for.[6] Laptops are computers that usually come in a clamshell form factor, again however in more recent years deviations from this form factor have started to emerge such as laptops that have a detachable screen that become tablet computers in their own right. Power supply. A power supply unit (PSU) converts alternating current (AC) electric power to low-voltage DC power for the internal components of the computer. Laptops are capable of running from a built-in battery, normally for a period of hours.[7] Mainboard. The motherboard is the main component of a computer. It is a large rectangular board with integrated circuitry that connects the other parts of the computer including the CPU, the RAM, the disk drives(CD, DVD, hard disk, or any others) as well as any peripherals connected via the ports or the expansion slots. Components directly attached to or part of the motherboard include: The CPU (Central Processing Unit) performs most of the calculations which enable a computer to function, and is sometimes referred to as the "brain" of the computer. It is usually cooled by a heat sink and fan. Most newer CPUs include an on-die Graphics Processing Unit (GPU). The Chipset, which includes the north bridge, mediates communication between the CPU and the other components of the system, including main memory. The Random-Access Memory (RAM) stores the code and data that are being actively accessed by the CPU. The Read-Only Memory (ROM) stores the BIOS that runs when the computer is powered on or otherwise begins execution, a process known as Bootstrapping, or "booting" or "booting up". The BIOS (Basic Input Output System) includes boot firmware and power management firmware. Newer motherboards use Unified Extensible Firmware Interface (UEFI) instead of BIOS. Buses connect the CPU to various internal components and to expand cards for graphics and sound. The CMOS battery is also attached to the motherboard. This battery is the same as a watch battery or a battery for a

Misplaced Modifier - Definitions and Examples

Misplaced Modifier s A misplaced modifier is a word, phrase, or clause that doesnt clearly relate to the word or phrase it is intended to modify. In prescriptive grammar, misplaced modifiers are usually regarded as errors. Mark Lester and Larry Beason point out that misplaced modifiers do not make sentences ungrammatical. Misplaced modifiers are wrong because they say something the writer did not intend to say (McGraw-Hill Handbook, 2012). A misplaced modifier can usually be corrected by moving it closer to the word or phrase it should be describing. See Examples and Observations below.

Greenwood, 1990) James Thurber on the Placement ofOnly Where to use only in a sentence is a moot question, one of the mootest questions in all rhetoric. The purist will say that the expression: He only died last week is incorrect, and that it should be: He died only last week. The purists contention is that the first sentence, if carried out to a natural conclusion, would give us something like this: He only died last week, he didnt do anything else, thats all he did. It isnt a natural conclusion, however, because nobody would say that and if anybody did it would be likely to lead to stomping of feet and clapping of hands, because it is one of those singy-songy expressions which set a certain type of person to acting rowdy and becoming unmanageable. It is better just to let the expression go, either one way or the other, because, after all, this particular sentence is of no importance except in cases where one is breaking the news to a mother. In such cases one should begin with: Mrs. Gormley, your son has had an accident, or: Mrs. Gorml ey, your son is not so good, and then lead up gently to: He died only last week.The best way is often to omit only and use some other expression. Thus, instead of saying: He only died last week, one could say: It was no longer ago than last Thursday that George L. Wodolgoffing became an angel. Moreover, this is more explicit and eliminates the possibility of a misunderstanding as to who died.(James Thurber, Our Own Modern English Usage: Only and One. The New Yorker, February 23, 1929.

Kesar variety is yellow in color and it has a tinge of green on the outside. It commonly come from Gujarat and is relatively cheaper than the Alphonso. Rajyasree describes Alphonso as the most beautiful mangoes he has ever seen. The variety comes from Ratangiri, Maharashtra and they have a huge market both locally and internationally. Alphonso mangoes are very delicious though they are highly expensive. The final variety that the article discusses is the Banganapalli type. It usually come fromTamil Nadu, and it was first introduced by the royal family of Banganapalli in Kurnool, Andhra Pradesh. Banganapalli mangoes are also very sweet and relatively cheaper compared to Alphonso (Rajyasree para1-9). However, apart from the varieties mentioned by the article, there exist other numerous varieties that are even popular than the above-mentioned. It appears as if Rajyasree covered mango varieties that are only common in India and ignored global varieties like Akbar, Apple, Betti Amba, Beverly, Banana and Batawi. The future of mango fruits is brilliant since there are various researches that are under way in various agricultural research centers in order to ensure that better mango varieties are introduced in the market that are more resistant to diseases, more delicious and varieties that can take a shorter time to mature.

Commentaries on Catullus Poetry (Poems 72 & 42) Essay Example for Free

Commentaries on Catullus Poetry (Poems 72 42) Essay There is great nuance and sensitivity in poem 72. We are told very early in the poem that it is addressed to Lesbia, Catullus love to whom a moderate number of poems in the collection are addressed (or concern). Earlier Lesbia poems had shown Catullus simple and insatiable love for my girl1 in very romantic language: for example, the lines describing the number of times he wished that they could kiss, in poem 5, which caused Aurelius and Furius to describe Catullus as a sissy poet2. However, in poem 70 we begin to see Catullus feelings for Lesbia turn sour as he tells us that a womans words to her lover are as trustworthy as those written on wind or water after presumably disbelieving her when she told him that there was no one she would rather marry than him, not even if asked by Jove himself3. If we assume that Lesbia was Clodia Metelli, we know that she was already married, so if her words are not suggesting that she has become available, she must be describing an unfulfillable wish and it is perhaps the fact that she says these words but is unable to act on her marriage vow which causes Catullus to be so untrusting4. Compared to the outbursts of joy and fury in the poems of what has been described as the first book, poem 72 is much cooler and more analytical5: Catullus here seems to be writing from his head rather than this heart. He uses, in the poem, two striking, and contrasting, similes to try to understand his love for Lesbia. He loved her (note the past tense) as a common might love his girlfriend (72.3), but in addition to that he loved her also as a father might his sons and sons-in-law (72.4). This is touching because it obviously implies that the latter relationship might be closer, with more of a connection, than the former, and, most importantly, that Lesbia was as dear to him as a son would have been, his own flesh and blood. Wray finds this comparison interesting because it is evidence against the long-standing assumption that Roman paternity was a tyrannical and grimly loveless exercise [of parental power]6 However, from here on in, the tone of love and affection darkens to one of cynicism. Now that he knows Lesbia he is has less affection for the woman. Catullus uses the language of obligation and Lesbia, as he sees it, has wronged him7. The poem ends with the enigmatic but powerful statement that, because of the hurt she has caused him, Catullus loves Lesbia more, but likes her less. At first, this may seem like nonsense and a contradiction in terms. However, when Catullus uses the verb amare (to love) he is describing his attraction to her, a kind of lust or natural allure, something that he seemingly has no control over. As much, then, as he does not like Lesbia for what she has put him through (i.e. her adultery), his love for her remains from the simpler time when he wished to kiss you just so many kisses (7.9) Poem 85 is where Catullus perhaps expresses the ambiguity and seeming contradiction inherent in his feelings best: I hate and I love. Perhaps youre asking why I do that? I dont know, but I feel it happening, and am racked. We can again see here clearly that Catullus is less a master than a subject8 of his emotions. The fact that he paints himself as being so emotionally powerless gives such poems as these a tragic quality; it also, arguably, helps to make Catullus such a universal poet who can still touch people through the ages. Poem 73 also carries some of the injustice that Catullus had expressed in 72: the attack on a friend who is probably Rufus (though we do not realise that the poem is addressed to him until it becomes evident later in the collection) is because he has returned honest kindness with no more than ingratitude. We now realise why the lampoons on Rufus alternated with Lesbia-poems at 69-72.9 This whole section of Catullus collection is a study of betrayal and adverse emotions. In the very first line of poem 72, Catullus talks about himself in the third-person, and this seems to be a literary device which emphasises the fact that he is not in control: it is Lesbia (and her actions) who is the subject of the poem. By declaring that his passion is more intense (72.5) Catullus leads us to think that he is about to, also, tell us how much he therefore loves Lesbia. However, by introducing the dichotomy in the last line between his love and dislike for Lesbia, our expectations are finally overthrown, which makes the contrast seem to be huge. It is by means of literary effects such as these that Catullus manages to express the almost inexpressible nuance of his emotion. This poem, ultimately, is most successful when read as part of the collection, as one can then draw links between the subtle issues in the Lesbia poems and see the complex web of emotions that Catullus paints for us. The development from a romantic, devoting relationship between Lesbia and Catullus to the trauma of that relationship breaking down is fascinating, and may reflect the emotions of millions of people alive today in similar situations. Poem XLII This poem is perhaps most interesting because it in itself can be seen as an imitation of the Roman practice of flagitatio10, which was a form of popular justice involving a crowd surrounding the man suspected of wrongdoing (or his house) whilst shouting roughly rhythmical phrases in unflattering language, demanding redress11. This was a very effective tactic because in a small community fear of defamation was strong; though it did, of course, rely on having friends willing to engage in the practice in order for what was seen as justice to be done. In this case, Catullus tells us that the crime was the theft of a notebook and the subsequent refusal to return it12. We can only speculate about the girl who stole them (though it has been inferred from the fact that she is described as an adulteress13 that she may well be Lesbia) and we also have just as little knowledge about what Catullus stolen notebook may have contained (and why it seems to be so precious to him): we may guess that it contained poetry, but that is no more than a guess. If that were true, the first two lines would contain a sweet irony: Catullus deploys poetry himself, hendecasyllables, as his flagitatio mob. He orders the hendecasyllables to come from everywhere (42.2), to metaphorically surround her. The image is an intimidating one: the lines of poetry have become men enclosing in on the suspect, shouting about her crime. When Catullus demands, Dirty adulteress, give back the notebook. Give back the notebook, dirty adulteress (42.11-12), he is using a technique common to flagitatio: the reversal of word order belonged to a very old popular custom as a means of intensifying the demand14. Catullus readership, we can surely assume, would have been aware of such devices and would at once have understood what Catullus was doing. Between the demands for the notebook, there is much invective and abuse hurled at the girl. Catullus tells us that she has an ugly gait, a face like a Gallican puppys (42.9) and is a filthy trollop (42.13) and a brazen bitch-face (42.17). Newman describes this as a fine example of carnival caricature included for primarily humorous effect15. However, it is not hard to see how these lines could be intended to have a hurtful effect, too, shaming the thief into repentance. Catullus is also all too aware of his social superiority10 and may simply be arrogantly showing his self-importance by making such a fuss over the loss of his notebook. This idea can be seen in, for example, poem 84, in which Catullus mocks Arrius incorrect use of aspirates which is surely caused by the politicians less privileged upbringing: Catullus attack, in this case as could be argued is the case in poem 42, is really then a display of his own aristocratic superiority. There is also a general link with poems such as 46, in which Catullus advertises his social status by documenting his travels with a sense of entitlement to faraway Roman lands. Perhaps the most pleasing feature of this poem is its conclusion. After all the fortissimo shouting, invective and carmina (chanting typical of flagitatio16), Catullus decides that he needs to change tone and tactics (42.22). He thus, seemingly sarcastically, ends the poem by asking for the notebook not by calling her a dirty adulteress but a virtuous lady (42.24), as we see that his invective has, somewhat comically, failed in its objective. On the other hand, the last line could more literally be interpreted as an acknowledgement of the flaws of this kind of public system of obtaining restitution. It does not seem unlikely that the girl would have responded more positively to flattery than flagitatio: Catullus could thus be making a wider point about the role of invective in society. The poem, in the collection, sits between invective poems on either side of it, with the previous three poems containing invective, some quite rude and obscene: in poem 43, for example, Mamurras mistress is described as being ugly from head to toe and, in poem 41, Ameana is called the female fuck-up. Perhaps, then, poem 42 is in the perfect location to show Catullus invective being tempered: it is in that poem that he shows that such anger does not always produce the desired effects. In poems 41 and 43, however, we are not shown any consequences of Catullus airing his opinions. We are simply told, in each, that there is an ugly girl in whom he is not interested: there is not intended to be the nuance and comedy value that poem 42 contains. To conclude, Catullus adopting the form of flagitatio for this poem underscores the poets association with the traditional purposes and values inherent in Roman invective17; not only does he derive authority from the tradition of the technique, but it also allows him to attack her harshly and eloquently. However, ultimately, he couldnt force a blush from, in Catullus words, the brazen bitch-face. We, therefore, see the limitations of invective: perhaps Catullus is admitting to us that we should see it as little more than entertainment. More importantly, though, the twist at the end of the poem is of stylistic and comedic value and can, perhaps, be said to show Catullus eloquence. Moreover, the fact that he feels no qualms at using such openly offensive language can be attributed to the fact that Romans would surely have sympathised with his demands for justice in face of a thief and may, also, be a reflection of his superior social status (not to mention the lower regard with which women were held generally) and consequent security in his right to show his anger in whatever way that he pleased. Ultimately, the poem makes character assassination into an appealing and technically adept art. Bibliography Dyson, J.T. (2007). The Lesbia Poems, in M.B.

Tupac Shakur Biography Essay -- essays research papers

Tupac Shakur 1971-1996 Born: June 16, 1971 in New York, New York, United States Died: September 13, 1996 in Las Vegas, Nevada, United States Ethnicity: African American Occupation: Rap Musician, Musician, Actor "Don't shed a tear for me ... / I ain't happy here / I hope they bury me and send me to my rest / Headlines readin' murdered to death."--from "If I Die Tonight" on Me against the World (1995) BIOGRAPHICAL ESSAY With his tattoo-splattered physique, piercing deep-set eyes, and shaved head, Tupac Amaru Shakur came across as middle America's worst nightmare, the darkest strain of hip-hop. To fans, Shakur was only "thuggin' against society, thuggin' against the system that made me," as he once rapped. Like some other rappers, Shakur was criticized for his sexist lyrics He celebrated his mother, Afeni, but was equally capable of debasing women in his music. The contradictions hardly ended there. In his last video, "I Ain't Mad at Cha," Shakur--newly arrived in Heaven--saluted an old friend for quitting the "thug life." In "Only God Can Judge Me," Shakur foresaw death bearing down on him, yet seemed unable to tolerate his rival, The Notorious B.I.G. and B.I.G.'s mentor, Sean "Puffy" Combs. Shakur's "Hit 'Em Up," the last single issued during his twenty-five-year lifetime, set new highs of profane rage against B.I.G., who was later gunned down after Shakur's own untimely death. Yet millions of fans found something meaningful in Shakur's troubled life and lyrics, like a thirty-two-year-old Detroit accountant buying her first Shakur album. "I've never supported that kind of music," she told the Detroit News, "but there was something so tragic about the way he died ... It's almost like I'm looking for answers." Politician Jesse Jackson also tried to explain Shakur's downfall and apparent appeal, telling the Los Angeles Times: "Sometimes the lure of violent culture is so magnetic that even when one overcomes it with material success, it continues to call." Acting bug bit early From his June 16, 1971, birth in New York City, Shakur's life read much like an epic melodrama. His mother, Afeni, and father, Billy Garland, belonged to the Black Panthers, a militant group dedicated to achieving racial equality. Just two years earlier, in 1969, Afeni and then... ...'s murder, "just a sad, ugly feeling, very creepy, very hollow," he said. "No art, no life, just ashes." Larger-than-life Vibe chief executive Kevin Clinkscales, however, advised fans against anymore "rumor-mongering," which he found disrespectful to Shakur's family. "These are not comic-book heroes," he told USA Today. "These are real people." That said, however, most agree that Tupac Shakur has won the larger-than-life immortality he craved so much. The sightings and resurrection theories place him in a select club that includes the late Kurt Cobain, Doors singer-poet Jim Morrison, and Elvis Presley. On that score, fans need not fear, as poet Nikki Giovanni acknowledged in her own tribute, "All Eyez on You": "don't tell me he got what he deserved he deserved a chariot and / the accolades of a grateful people / he deserved his life." Nor did Giovanni stop there, getting her own "Thug Life" tattoo to honor Shakur's memory, telling the Chicago Tribune: "Young black men are in a holocaustic situation." So long as that persists, fans insist, Tupac Shakur's musical legacy will be hard to deny.

Representation of Women in Horror Essay

Since the inventions of television and film, media influences have become extremely important in modern society with people constantly being inundated by images and messages that come from film, television, magazines, internet and advertising. Researchers and theorists such as Carol J. Clover and Jean Kilborne believe that the fact that people are going to be affected by the media is absolutely unavoidable. Films can act as guides to how people, particularly women, should act and look. Women in horror are typically shown as the ‘damsel in distress’ and are usually attacked by the killer after committing a sinful act like having sex or misusing drugs or alcohol. The females are usually very attractive, slim and quite often blonde. These characteristics are usually reinforced by seductive body language, heavy make-up and vulnerability giving the message that women are unable to take care of themselves and have to look a certain way to fit into society. Many directors have tried to change the messages in horror films my introducing the ‘Final Girl’ where it is a female who is a virgin and does not do drugs or consume alcohol that fights back and becomes the ‘hero’ rather than a male, giving the unrealistic message that if people don’t do wrong, nothing bad will ever happen to them but horror films are notorious for presenting women in a particular way, often making them victims of sexualisation. The representation of women not only influences the way that females think they have to be or the way males think that women should be but they also have a great impact on the values in society. Sexualisation in the representation of women is predominantly obvious in horror films, specifically Psycho, directed by Alfred Hitchcock, Rosemary’s Baby, directed by Roman Polanski and Scream, directed by Wes Craven. All three movies display sexualisation using gender stereotyping, victimisation and the male gaze. Scream is known to be extremely unrealistic, being on a more imaginary level rather than a realistic one and is full of violence and sexuality while reinforcing the cultural and social values at the time of its release in 1996. It focuses on the issues of power, danger, sex and anger in females of the 1990s. It is important for adults to understand these issues in teenage girl’s lives although the ways they are presented in Scream make them seem far more disturbing than they actually are. Just like popular culture, Scream has used ideas influenced by other films but in attempt to capture and address different audiences, the messages are presented in different ways. The plot of the original Scream movie is similar to many modern day teenage films, set in American suburbia with white, affluent homes and a quiet community, which is ‘preyed on’ by a masked serial killer. The film begins with the stalking a brutal killing of a blonde teenage girl who is home alone and, ironically, about to watch a horror movie. After her murder, the focus moves to Sidney, who becomes the next target. A year prior, Sidney’s mother was found raped and murdered and on this particular weekend Sidney is home alone, as her father has gone away on business. As a result of her grief for her mother’s death, she constantly resists the recurring pressure for sex from her boyfriend who she has been dating for two years. In the meantime, news reporter Gale Weathers obsesses over the story of the recent murders. The subsequent events lead to a party during which Sidney decides to have sex with her boyfriend, Billy as the murderer gets most of the boys out of the house by calling to say that their principal has been killed and is hanging from a goal post at the school. Following the gruesome battle, an injured and bloody Sidney realises that Billy and his friend Stu have been working hand-in-hand as the killer, ‘Ghost Face†. Billy claims that his motive for killing her mother was that her mother was sleeping with his father and consequently, his mother left them. With assistance from Gale and Randy, Sydney kills Billy. Scream’s most dominant issues that are raised are common issues in the lives of teenage girls; sexuality and virginity, femininity and its connection to power and identity as it is shaped and influenced by the media, experiences and relationships, particularly a girl’s relationship with her mother and in this case, the death of her mother. Director Wes Craven confronts all of these issues and solves them in powerful ways which encourage girls to defend themselves by being assertive and finding their identity in their own  way and in their own time. Scream’s main focuses are sexuality and virginity and how they have an impact on anxiety in young women and have an effect on the reputation on the girl –â€Å"your mother was a slut bag,† Sidney is told.

Banning Fireworks Essay

Fireworks are used for special events in the whole world, a lot of people have unlimited access to buy fireworks. When special events are coming up people get excited to watch fireworks exploding in the sky. Some people do not realize fireworks are dangerous in many ways. Something good I can tell about fireworks is, when I was a child I used to play with fireworks, and it was funny to watch them explode. This Christmas my brother and cousin were playing with fireworks but they had an accident with only one firework, my brother lit a firework, then my brother and cousin ran away from there but the firework flew against my cousin burned at his ear, then the same firework burned my brother in his arm. The first reason fireworks should be banned is that fireworks cause accidents to some people, and in some cases people die to play with them. People between 6 and 19 years old have more than 50% of provability of hurt themselves playing with fireworks. Fireworks are made with different kinds of ingredients but the most dangerous is the gunpowder because it is form part of the base of the fireworks and it is very explosive. When fireworks explode they produce fire, also fireworks explode so quickly that some people get burns and wounds caused for the fire emitted for fireworks when they explode. Fireworks are most use in holidays or a special event such as Christmas, New Years, Independence Day, and many other events such as thematic parks or zoos. Fireworks should be banned in the whole world because they are dangerous to the person operating them and to bystanders,  they start fires when landing in flammable materials and nature, and they cause lot pollution. One reason fireworks should be banned is that they cause fires after landing in flammable materials and nature. Some fireworks still on fire when they are landing, some houses, business and personal property such as cars are damaged because of the fireworks. Sometimes fireworks land over flammable materials such as paper, cartons, trash, causing fires. Nature such as trees, gardens and water are affected as well, water is one of the most important natural resource that is protected for many environmental groups, and one of them is the environmental group of San Diego Coast Keeper. Last year Sea World applied for one permit to use fireworks in their shows, to avoid being sued for the environmental group Coast Keeper, Sea World is going to be the first park in the whole nation â€Å"to obtain a pollution discharge permit for exploding fireworks over a body of water, to ensure no harm is occurring to Mission Bay†. (Rogers, 2007). Fireworks cause pollution that affect people and environment. A lot of people in the whole world have a respiratory disease such as asthma, hyperventilation and lung cancer. The human respiratory system provides oxygen to the body and lungs help to clean and remove all body wastes, also lungs help to filter out infectious agents cause from smoke and other pollutants such as fireworks. When the environment is contaminated with pollution such as the one that fireworks emit, the level of contaminants materials increase extremely that people that have pulmonary diseases cannot breath because of the contamination in the air. Asthma in one of the most dangerous diseases in the world, asthma is a condition in the respiratory system that cause spams in the lungs. People that are more affected with this condition are children, but they usually get over the respiratory conditions as they grow old. In holidays some people go to the hospital because of the pollution in the air, because the environment is contaminated with the fireworks smoke. The environment of this world is already damaged with smoke and residues of heavy metals that stayed in the air; the pollution reduces for fireworks are equal to a thousand burned tires in only one day. Fireworks are only one of many factors that cause pollution in the  world. Fireworks have a negative impact to the world, fireworks affected people when they play with fireworks in a lot of ways, and health is one of them. Fireworks start fires damaging property and nature, and the damage is irreversible, some families have lost their houses and personal property that they struggled to pay for it. The nature is something that after damage takes years to regenerate, also the wildlife is affected because they live in this environment as well; the forest is one of the most affected habitats. The contamination is a big factor that it is really serious to the planet. The biggest polluter is the human being, and the human cause all the pollution that affect animals, plants, themselves, the whole planet in general. Everybody should have respect for the environment because everybody is part of it, is the environment is damaged everybody is affected as well. Children are the future of the world environment, everybody have to teach them how to take care of the environment, people need to put effort in to the environment taking care of it, the government is an essential part to take care for the ecology, but the people is the one who decides the course of their habitat, stop blames the government for giving permission for using fireworks or not, and get started taking care of the planet. Do not change the magic of the world and its beauty for fake magic like fireworks. Think about the environment first. Rodgers, T. (2007, November 29). Fireworks permit for Sea World considered.

Lines and Angles in SAT Math Prep and Review

Lines and Angles in SAT Math Prep and Review SAT / ACT Prep Online Guides and Tips Knowing your lines and angles is crucial for mastering SAT and is one of the foundational steps of geometry. Before you can tackle some of the more complex multi-shape problems that often appear towards the end of the test, you’ll need to know just how to solve for all your missing angle measures. Almost without fail, there will be exactly two problems on any given SAT on lines and angles (note: these problems are distinct from questions on lines and slopes, which are covered in a separate guide). Though this is a small percentage of the test in and of itself, line and angle knowledge provides the backbone for other geometry problems and so should be ranked high on your studying priorities. This will be your complete guide to lines and angles on the SATwhat they are, how you’ll see them on the test, and how to solve these types of questions to maximize your points on test day. Properties of Lines and Angles Before we get into how lines and angles function, let’s take a second to define what these terms mean. A line is a completely straight marker, meaning it has no curvature. It can either have termination points (and will be called a â€Å"line segment†) or go on infinitely. Its degree measure is always 180 °. Parallel lines are two or more lines that are a set distance apart (equidistant) and never meet. They travel in the same direction continuously. Perpendicular lines meet each other at 90 degree angles. An angle is the meeting of two lines. The measure of how they meet is expressed in degrees, and the point at which they intersect is called the angle’s â€Å"vertex.† Line and Angle Equalities Most of what you’ll need to know about lines and angles on the SAT is when and how they will be equal or supplementary to one another. Equal angles (or lines) are angles (or lines) that have the same measurement. Supplementary angles are angles that add up to 180 degrees. Because all these angles form a straight line and a straight line equals 180 degrees, the three angles are supplementary. Opposite Angles When two (or more) lines intersect, they form a series of opposite angles. Angles that are exactly opposite will always be equal to one another. Now let’s look at an opposite angle SAT problem. Here, you can see that the lines l and k intersect such that the sum of angles p and x make an angle that is exactly opposite angle m. This means that, when we add together angles p and x, their sum will be equal to angle m (because opposite angles are equal). 25+x=40 x=15 So our final answer is A, 15. Opposite Interior Angles When there are two parallel lines that are crossed by another line (called a transversal), the angles on alternate interiors will be equal to one another. And the angles on the same side of the transversal line and the same side of their respective parallel lines will also be equal. That may be difficult to picture, so let’s look at a diagram: (Note: when you are told that two lines are parallel on the SAT math section, the problem will almost always involve opposite interior angles in some way.) Now let’s look at an opposite interior angle SAT problem. We are told that lines l and m are parallel, so that means the three vertical lines are transversals. We can see that the angle to the far left is marked as 89 degrees and it is an opposite interior angle to angle r only. This means that r=89 degrees, as opposite interior angles are equal. So our final answer is A, r. Typical Line and Angle Problems Almost every line and angle problem is given to you as a diagram problem. You will be presented with a series of givens and then told to find a missing value of some kind. Almost always, this requires multiple steps and the use of multiple pieces of line/angle knowledge. For instance: This is a very typical line and angle problem, so let’s go through it. We are told that angle f is 85 degrees. This means we know that angle b is also 85 degrees because it is opposite f and opposite angles are equal. We are also told that c is 25 degrees. This means that g must also be 25 degrees because it is opposite angle c. And finally, we know that a line equals 180 degrees. This means that, in order to find angle a, we can say: a+25+85=180 a+110=180 a=70 So our final answer is C. As we said before, this question is representative of most line and angle problems you’ll see on the test. Based on your givens, you must use your knowledge of opposite angles (opposite angles are equal) and your knowledge of the degree measure of a line (a line is 180 degrees) in order to put together all the clues and solve your problem. The other kind of line and angle problem you may see will involve triangles. In these questions, you must not only put together multiple pieces of angle knowledge, but triangle knowledge as well. Generally, you will not need to know more than the fact that all the interior angles in a triangle add up to 180 degrees, but check out our guide to SAT triangles if you are rusty on your triangle geometry(coming soon!). Because we are told that lines l and m are parallel, we can guess that our answer likely has something to do with opposite interior angles. We also know that, to equal 180 degrees, our angles must either complete a triangle or a straight line. With those clues in mind, let’s go through our answer choices. Option A gives us k,n, and r. We know from our opposite interior angles that k and r are equal, and that n, s, and t are equal, but this information helps us complete neither a triangle nor a straight line. We can eliminate answer choice A. Answer choice B gives us k,p, and s. Again, from our opposite interior angle knowledge, we know that k and r are equal, and that n, s, and t are all equal. Because s=n, we can form a triangle with our given angles. And because s=t, p is given, and opposite interior angle equalities means that k is equal to the unknown angle counterclockwise above t, then our known values can also form a straight line of 180 degrees. Whether they are forming a triangle or a straight line, we can find 180 with the given angles of k,p, and s. We can stop here; we found our solution. Our final answer is B. You can see here that the lynchpin for solving the problem was in your understanding that opposite interior angles are equal. And though you could have also found your required 180 degree measurement using a straight line (as we did above), it was faster to use the triangle. For both ease of problem solving and knowing how to solve the more complex geometry problems, your knowledge of lines and angles should definitely be supplemented with triangle study. So don’t forget to brush up on your SAT triangles!(coming soon!) Let's take a look at the tips for unlocking SAT angle problems. Tips for Solving a Line and/or Angle Problem As you saw in the earlier examples, most line and angle problems require you to go through multiple steps before you find the right answer. And most of the time, you must solve the question piece by piece in order to unlock the final solution. As you go through this process, keep in mind these three tips: 1) Write in your givens If you are given a diagram in which your givens are NOT written in, then write them in yourself! Sometimes, seeing the numbers on the page can make all the difference in the world between a difficult problem and an easy one. You’ll also be far less likely to mix up your numbers and variables if you keep your work on the page instead of in your head. 2) Work from your givens to find the next puzzle piece Sometimes, it can be tricky to know where or when or in what order to work through a problem. Take a moment to find what you can before you worry about how to go forward. If you have opposite angles, write in the measure of the angle opposite you're given. If you have angles that make a straight line, find the value of the missing variable. Immediately find the missing pieces that you can, and that information will often lead you straight to your solution. 3) If necessary, use plugging in answers or plugging in numbers If you find yourself stuck (or there is literally no other way to solve the problem), then whip out your PIA or PIN knowledge. Sometimes the process can be slower than a straight solve, but these strategies will almost always get you where you need to go and so can be worth the extra seconds. Ready, set...go! Let's test that newfound knowledge! Test Your Knowledge 1) 2) 3) 4) Answers: A, D, A, D Answer Explanations: 1) This is a question that cannot be solved without using plugging in answers. We can see that x, y, y, and y all make up a straight line (which equals 180 degrees). So let us express that as an equation. x+3y=180 Now, we have no other information (other that that x and y are both integers), from the problem, so now we must look to the answers. Let us start with the answers that end in 0 as those are easiest to work with. If these do not work, then we can eliminate them and try the answers that end in 5. Let’s begin by plugging in our middle value, C, in place of x. If x=40, then: 40+3y=180 3y=140 y=46.67 140 is not evenly divisible by 3, so we can eliminate answer choice C. Let us now try answer choice A, x=30. 30+3y=180 3y=150 y=50 When x=30, both x and y are integers. This fulfils our question premise and so is our correct answer choice. Our final answer is A, x=30 2) Let us solve this question by finding the values of all the angles we can. Angle a is opposite the 60 degree angle, and so angle a=60. We can also see that angles a and b are supplementary, as they form a straight line. This means that: a+b=180 60+b=180 b=120 We can also see that angle e is supplementary with the 70 degree angle. So: e+70=180 e=110 Now, we need only find angles c and d. From our knowledge of triangles (coming soon!), we know that the interior degrees of a triangle add up to 180 degrees. So angle c must be: c+60+70=180 c=50 And because c and d form a straight line and are therefore supplementary, we can find angle d by saying: c+d=180 50+d=180 d=130 Which means, that of all the degree measurements that we found (a=60, b=120, c=50, d=130, and e=110), angle d is the largest. Our final answer is D, d. 3) Because we are told that lines l and m are parallel, we can guess that this problem likely involves opposite interior angles. Because we are familiar with our opposite angles and our opposite interior angles, we can see that angles s, u, and t are all equal. We can also see that angles r and s are supplementary, as they form a straight line. And if r=91, then let us find angle s: r+s=180 91+s=180 s=89 We already said that angles s, u, and t are equal, so they are all equal to 89 degrees. For the final step, we must add t and u. So: t+u = 89+89=178 So our final answer is A, 178. 4) In this question, we are working with multiple variables. Luckily, we can find our value for x and then use it to find our y value. The angle measures 4x and 2x make a straight line, so they are supplementary. This means that: 4x+2x=180 6x=180 x=30 Now, we can find y by using our x value in one of two wayseither because angle y is opposite (and therefore equal) to angle 2x or because angle y makes a straight line with 4x (and is therefore supplementary). So we can say that: y=2x y=2(30) y=60 Or, we can say that: y+4x=180 y+4(30)=180 y+120=180 y=60 Either way, our answer is y=60. So our final answer is D. Whoo! Your brain is on fire (in a purely metaphorical and non-lethal way, of course). The Take-Aways Lines and angles are often simpler than you may think. The tricky thing about these types of questions is generally in the number of steps it takes to get to the final answer. Just remember your equalities, keep your work organized, and do your best to avoid careless errors. Once you’ve locked down lines and angles, you will be well equipped to take on the more and more complex geometry problems the SAT can put in front of you. What’s Next?

Project management Essay Example | Topics and Well Written Essays - 2000 words - 8

Project management - Essay Example We began working as a group and not individuals. The fourth stage was performing, where having known one another and chosen common goals, we began working on them. The final stage in this model is usually adjourning which is the splitting of the group so that individual members go separately, after the goals have been achieved. The second model we could use is the Gersick’s Punctuated Equilibrium Model which is a three-stage model as explained by Sharma (78). In its application, which did not apply in our case works by a group coming together almost naturally bound by a common framework. In its first phase, the members come together and establish a framework in which slow progress is observed. In the second phase called midpoint, the members discuss the framework and make decisions which assume they can lead to progress. In the last phase, action is taken according to the decisions made in stage two and the group experiences effects of the decisions they made. From these two models, the first one best describes how our group was developed. We came together and collected our ideas. After that we voted for the best ones and went about achieving them. After achieving our goals, the group was dissolved. In developing the group, we had nine factors that we observed as they could affect it and which â€Å"Organizational Development Portal† (n.p.) highlights. One of these was our goals and objectives which we had clearly set. These worked positively because we knew what to do. The second was utilizing our group resources which we controlled well, such that there were no complaints. The third factor was conflict resolution, which was a bit difficult to handle since all the members felt equal thus could not listen to each other. This was a negative factor. The fourth factor was leadership which we had constructed by voting using preferences and secret ballot. The leaders were respected because they were chosen by the members. This was positive. The fifth
