Theory of Parabolas Essay Example for Free

Theory of Parabolas Essay A parabola is designed on a basic formula, Y=ax^2+bx+c, which allows it to achieve a curve not seen in a normal line graphed using a Y=mx+b format. To the left is a graph who’s formula is y=x^2, where a=1, b=0, and c=0. I have isolated the (a) factor to see its effects on the parabola. Below is a graph where I have changed the (a) multiple times. The result is that as the (a) decreases, the mouth of the parabola widens due to the fact that (a) is essentially the slope of the parabola. Now, watch what happens when the (a) becomes negative. Now the mouth of the parabola is opening down and as we increase (a), the parabola widens. When (a)1, the parabola closes up horizontally. So from this, we can infer that if (a) is 0, then the result will be a straight line going along the X axis which is no longer a parabola. Now we will look at how the (b) factor changes the parabola, below is the origional graph from the top of the paper except the red line represents the same parabola with a (b) added onto it. The original equation was Y=x^2(blue line) and the new equation is Y=x^2+x(red line). The change is moving the vertex of the parabola left ? and down ? but the shape of the parabola it’s self is unchanged. Here are some other examples of changing (b) in a parabola with a steady (a) As seen in the graph, (b) only moves the parabola to the sides and down (as the numbers increase, the vertex moves left and down and decreasing is vice versa), but somehow fails to move the parabola up past the point X=0 on its own (making the (a) negative will flip the parabola). So now we have a slope (a) and a vertex (b), but we still need our Y-intercept which will be our (c) As shown from the graph, our parabolas Y-intercepts match up with our (c) factor, completing the equation -Fun fact, the word parabola came from the Greek words para, meaning beside, and bole, meaning to throw

Courage Shown In The Book To K :: essays research papers

Courage Shown In The Novel   Ã‚  Ã‚  Ã‚  Ã‚   Do you think that courage is an important part of a novel? Well in the book, To Kill A Mockingbird, much courage was shown. Courage is standing up for what you believe in, or doing something that is hard and takes many obstacles to overcome, or can be as little as saying, â€Å"No† to someone. Atticus, Jem, and Boo showed much courage in the novel.   Ã‚  Ã‚  Ã‚  Ã‚  First, one of the main characters, Atticus, showed much courage. The first thing in the book that shows it is what he did to a tradition in his family. For many years the Finch family had a custom that the oldest one would stay on the land. Atticus didn’t want to and broke a family tradition that was kept for a long time. I know that I wouldn’t be able to have that much courage to break a tradition that was kept in my family for that long. Another way that Atticus shows courage is by defending Tom Robinson. No other man in Maycomb would defend him. Atticus stood up for what he believed in, and did the right thing.   Ã‚  Ã‚  Ã‚  Ã‚  Also, Jem shows a lot of courage throughout the novel. He was the one that touched Boo’s house and also went to his house late at night to go to the Radley’s house. He also read for one of the meanest people in Maycomb, Mrs. Dubose. Even though it was a punishment to make him read to her, he could have been miserable about it. After a while though he thought it wasn’t to bad. He was reading to the meanest person, and doing it with no complaints, after a little. He also shows a lot of courage by going to the trial of Tom Robinson with Scout and Dill. He knew that he wasn’t supposed to go to it but did anyway, because he wanted to see what it was like.   Ã‚  Ã‚  Ã‚  Ã‚  Finally, Boo Radley showed the most courage, in my point of view. When he went out that night to save Scout and Jem from Bob Ewell, it was the first time in a long time that anyone has saw his face. Also, I think that he

History of Internet Essay

The term ‘Internet’ was coined on October 24, 1995. However the origin of the internet and related concepts are much older. The present day Internet is the revolutionized face of the nascent day communication system and is the most successful examples of benefits of sustained investment and commitment to information infrastructure (Leiner et al. , 2003). The unprecedented integration of collaboration, dissemination embarked by a series of gradual changes that the society has undergone with respect to the communication and connectivity needs. As described by Kristula (1997), it was in 1957 that the USA formed ARPA (Advanced Research Projects Agency) within the DoD (Department of Defence) to establish US lead in science and technology applicable to the military. Until 1960’s, the computers operated almost exclusively in batch mode, where programs were punched on stacks of cards and assembled into batches for the data to be fed in the local computer center. The need for the time sharing system had already set the stage for research and development work to make the time sharing possible on the computer systems. In an article, Hauben (1995), stated that the time sharing system led the foundation for the Interactive Computing, where the user could communicate and respond to the computer’s responses in a way that batch processing did not allow. Both Robert Taylor and Larry Roberts, future successors of Licklider as director of ARPA’s IPTO (Information Processing Techniques Office), pinpoint Licklider as the originator of the vision which set ARPA’s priorities and goals and basically drove ARPA to help develop the concept and practice of networking computers. Licklider has been described as the father of modern day network, having laid the seeds of the Intergalactic network, the initial prototype of the Internet today. The vision of the interconnection and interaction of diverse communities guided the creation of the original ARPANET. The APRANET pioneered important breakthroughs in computer networking technology and the ability to collaborate and use dispersed resources (Winston, 1998). In 1962, Paul Baran, a RAND research worker introduced the concept of ‘Packet Switching’, while working towards the need of the U.  S. government to take command and control of any kind of nuclear attack. Packet switching was crucial to realization of computer networks and described breaking down of data into ’message blocks’ known as packets / datagrams, which were labeled to indicate the origin and the destination. Baran’s scheme was aided by telephone exchange methodology being used by information theory. The data was now sent in discrete packages around a network to achieve the same result – a more even flow of data through the entire network. The same concept also developed by British computer pioneer Donald Watt known as Davies’s Pilot Ace. Baran’s Distributive Adaptive Message Blockswitching became Watt Davies’s ‘Packet Switching’. The first host connected to the ARPANET was the SDS Sigma-7 on Sept. 2, 1969 at the UCLA (University of California in Los Angeles) site. It began passing bits to other sites at SRI (SDS-940 at Stanford Research Institute), UCSB (IBM 360/75 at University of California Santa Barbara), and Utah (Dec PDP-10 at the University of Utah). This was the first physical network and was wired together via 50 Kbps circuits. ARPANET at this stage used NCP (Network Control Protocol). By 1973, development began on TCP/IP (Transmission Control Protocol / Internet Protocol) and then in 1974, the term ‘Internet’ was used in a paper on TCP/IP. The development of Ethernet, in 1976, supported high speed movement of data using coaxial cables and led the foundation for the LAN (Local Area Network). Packet satellite project, SATNET, went live connecting the US with Europe. Around the same time, UUCP (Unix –to-Unix Co Py) was being developed by AT&T Bell Labs. The need to link together those in Unix Community triggered the development of the Usenet in 1979. Using homemade auto dial modems and the UUCP, the Unix shell and the find command (that were being distributed with the Unix OS), Bellovin, wrote some simple shell scripts to have the computers automatically call each other up and search for changes in the date stamps of the files. The Usenet was primarily organized around News net and was called as the ‘Poor Man’s ARPANET’, since joining ARPANET needed political connections was costly too. Woodbury, a Usenet pioneer from Duke University, described how â€Å"News allowed all interested persons to read the discussion, and to (relatively) easily inject a comment and to make sure that all participants saw it. † However, owing to the slow speed, the coding language was soon changed to ‘C’, thus becoming the first released version of Usenet in C programming popularly known as A News. By 1983, TCP/IP replaced NCP entirely and the DNS (Domain Name System) was created so that the packets could be directed to a domain name where it would be translated by the server database into the corresponding IP number. Links began to be created between the ARPANET and the Usenet as a result of which the number of sites on the Usenet grew. New T1 lines were laid by NSF (National Science Foundation). The Usenet took an unexpected explosion, from 2 articles per day posted on 3 sites in 1979, to 1800 articles per day posted at 11000 sites by 1988. By 1990, the T3 lines (45 Kbps capacity) replaced the T1 lines and the NSFNET formed the new backbone replacing the ARPANET. The beginning of 1992 marked the establishment of a chartered Internet Society and the development of the World Wide Web. The first graphical user interface, named ‘Mosaic for X,’ was developed on the World Wide Web. By 1994, the Commercialization of the Internet emerged in the form of the first ATM (Asynchronous Transmission Mode) was installed on the NSFNET. The free access of the NSFNET was blocked and fee was imposed on domains. This describes the series of events that shaped the history for the past two decades, ever since Internet came into existence. The Internet technology is continuously changing to accommodate the needs of yet another generation of underlying network technology. Hoping that the process of evolution will manage itself, we look forward to a new paradigm of Internet Services.

Apush Dbq American Revolution

Though some may try to argue that the American Revolution was not a real revolution since the upper class was not displaced, it was in fact a revolution because it transferred power from an entrenched British monarchy into the hands of local state legislatures. The American Revolution was representative of a great change which occurred in the way that in Britain, parliament viewed Americans as a small cluster of people who could be taxed without representation, to where in America the government was able to see how each individual could contribute to the economy, government, and the overall well-being of America.This idea came about from the increasingly more harsh and authoritarian taxes that were being placed on the colonies, without representation, from British monarchy. In reaction to the Tea Act, one of the taxes placed on imported goods to America, the New York Sons of Liberty wrote several resolutions to protest against it.These resolutions were signed by all different social classes, which signifies a change in society, because while in Britain only the wealthy and educated were permitted to participate in governmental choices, a very broad spectrum of society was able to be an active participant in how they wanted their government to be run. Although the lower class was not necessarily in congress, their ideas were able to represented by the people that they elected to express their ideas.Some who wish to argue the idea that the American Revolution was not a full revolution may bring into light the women of the revolution, and how there was not a huge change for them. Even though their was not an extremely significant change for them, American women were given a multitude of rights that were not given to women in Britain at the time. The women of America were able to go out to war with the men to protect them, and at times even take their place when a man was wounded and could not fulfill his duties on the battlefield.Additionally, they were often left in charge of the business and upholding of the household when their husbands went out to war. In summation, American women played many roles that were not typical of them in that time period; showing a revolutionary new way of thinking that involved women. After the surrender at Yorktown, a cartoon by James Gillray was made as a warning to the British that since they were able to defeat the British once, they could do it again should they try to overtake America and their freedoms again.While this act in itself was not a revolution, it was representative of the revolutionary ideas in the works of the United States of America. The American Revolution was the transference of power from a monarchial government to that of a representative democracy that was able to reflect the ideas and desires of all free white men of America; indicating that it was in actuality a revolution and not an expeditious rebellion.

Costco case analysis until 2008 Essay Example | Topics and Well Written Essays - 500 words

Costco case analysis until 2008 - Essay Example This is the reason why it is not charging credit cards because current low margins do not cover this fee. Costco can solve this problem by using both the cash and credit card system of payment, but those people who want to pay using credit cards, an extra 2% should be charged to their bills in the lieu of banking fee. This method will be acceptable to most of the customers as the prices in Costco are already very low and people who use credit card can still make a saving even if they pay for extra 2 percent banking fee. This will help Costco attract a wider customer base and at the same time not lose out on their margins. Costco has also limited itself in the membership program. Special offers and discounts are given only to members of Costco. This is a dangerous policy because many potential customers who want to avail special offer cannot avail them and hence they do not shop at Costco. What Costco can do here is that they should publish and send out special discount coupons throug h direct mail and magazines. These coupons should be redeemable at Costco stores and this way Costco will serve a wider audience and will be able to attract larger pool of prospective customers. Many other shops and competitors to Costco provide ancillary services to its customers. However, Costco does not provide these services to its customers. Costco is operating at very low margin which does not give enough leverage to Costco to provide these services. This can be tackled by Costco advertising that should compare its costs with other retailers and should point out that Costco is competing on cost and the value of saving that Costco provides is greater than ancillary services that other retailers provide. This will encourage many more customers to buy from Costco and it will also help to increase Costco’s sales and revenue. It can be concluded from the above discussion that although Costco is doing pretty well, it needs to look at the external environment and should

Middle East culture in business Essay Example | Topics and Well Written Essays - 500 words

Middle East culture in business - Essay Example This research will begin with the statement that in this age of globalization, partnerships and outsourcing are becoming to be the model of businesses.   In this deal, it is important to try and learn the customs and traditions of the country, one has to deal with so as not to offend the hosts. The Middle East is a very large group of diverse culture. The researcher will begin with the discussion of religion.   Religion is a way life for the Muslims, and it has an important bearing when doing business with them.   Muslims pray five times a day, so sometimes, in meetings, they have to be excused. Employers should also understand that Muslim employees have to leave their workplace on Friday afternoons for the mosque.  Ã‚   In contrast, religious practices of Christians found in the Western and Asian culture do not interfere with business because they do only go to Church on Sundays and special occasions and has no need to leave their places when praying. Like the Islam nations, Western faith is based on the Bible. It is not good to do business with Muslims during their celebration of the holy month of Ramadan because businesses are closed and they tend to spend the holidays with their families or at their holy shrine. They observe fasting from dawn to dusk and extensively engaged in their worship, so business must wait as it becomes their second priority.   The month of Ramadan is observed every tenth month of the Islamic calendar. Westerns do not observe this month-long religious activity that often interferes with business.
