...Unit 1 When we manipulate expressions and equations, we realize that there are basic properties that govern what we can and can't do. One of those properties is the Commutative Property. Let's consider this property in our discussion. Is there a commutative property of subtraction? In other words, does order matter when subtracting? Why or Why not? Please provide an example to explain your reasoning. Please share any trick or mnemonic device to help you recall what this property is or how to use it. There is no Commutative Property in subtraction. Yes order does matter subtracting, you can not subtract a larger number from a smaller number, such as: 3-6 = this subtraction can not be done but if you turn it around and subtract the smaller number from the larger number it will work: 6 -3 = 3. In all the properties you can not use subtraction or division, just addition and multiplication. Unit 2 As we know, a set is just a collection of objects that are similar in some way, like a gaggle of geese, pride of lions, or an army of ants. To further classify our world, we can create subsets from a larger set. Let's consider the idea of a subset for our discussion. • Give an example of a subset and a proper subset. Explain the difference between a subset and proper subset. • Can any set be a proper subset of itself? Give an example of why or why not. A = {Lions, Tigers, Jaguar} B={Lions, Tigers, Leopard, Cheetah, Jaguar} *Everything that is in A is in set B therefore it...

...Strategies to Overcome Math Anxiety Classroom Skills * Your instructors want you to succeed. Remember, they are unsuccessful unless you are successful. Your instructor wants you to learn the material and is willing to help when you ask questions. * Ask questions when you become stuck or as soon afterwards as possible. * Make your questions as specific as possible. It is easier for your instructor to answer a question such as, “I don’t understand how to solve for x when the equation begins with a fraction” than “I just don’t understand this section. Can you help me?” In addition, by making your questions as specific as possible, you can sometimes find the answer on your own. * Even if you do not understand what the textbook explains yet, read it over before class. When you have some knowledge about the concepts before they are presented, you will find them easier to understand. * Embrace word problems. Although they are sometimes corny, word problems are the gateway to using your math in real life. * If you are taking a math class at your local campus, sit near the front of the class. * Take advantage of your campus’s help sessions and the CME online coaching. Studying for Exams * Study everyday instead of cramming for exams. Review previous materials everyday for about a half hour to help you retain skills. * Do not multitask when you are studying. Cognitive psychologists find that multitasking makes you less efficient at everything...

Afleveres onsdag den 6. feb. a) Nulpunkterne for den funktion f, hvis graf er vist i opgavebeskrivelsen er: b) Hvorfor nulpunkterne er interessante når fortegnsvariationen for f skal bestemmes. Ved nulpunkter kan funktionsværdierne skifte fortegn og det er netop derfor, at de er interessante. c) Bestemmelse af fortegnsvariation for f. Funktionen f har positiv fortegn i intervallerne og Og negativ fortegn i intervallerne og d) Aflæsning af lokalt maksimum og lokalt minimum for f lokalt maksimum er -3 og lokalt minimum er 1. e) Aflæs på grafen monotoniintervaller for f. Dvs. aflæs de intervaller, hvor funktionen er voksende og de intervaller, hvor funktionen er aftagende. Funktionen er voksende i intervallerne og Funktionen er aftagende i intervallerne g) Bestem f´(x). Både uden hjælpemidler og vha. Maple. Uden hjælpemidler: De forskellige led differentieres og vi starter med x3. Tretallet rykkes ned foran x og der trækkes én fra opløftet værdi så det bliver 3x2. Dernæst differentieres 3x2 igen rykkes totallet ned og der trækkes én fra den opløftet værdi så det bliver 2x. Dette ganges på tretallet som i forvejen stod foran x’et og vi får 6x. Når 9x differentieres fjernes x’et og tilbage står 9. Alle konstanter der differentieres fjernes og det færdige differentieret f ser således ud: Med hjælpemidler: I stedet for Maple bruges TI-89 til at differentiere og følgende kommando: Naturligvis fås samme resultat...

...I recently got an email from a founder that helped me understand something important: why it's safe for startup founders to be nice people. I grew up with a cartoon idea of a very successful businessman (in the cartoon it was always a man): a rapacious, cigar-smoking, table-thumping guy in his fifties who wins by exercising power, and isn't too fussy about how. As I've written before, one of the things that has surprised me most about startups is how few of the most successful founders are like that. Maybe successful people in other industries are; I don't know; but not startup founders. [1] I knew this empirically, but I never saw the math of why till I got this founder's email. In it he said he worried that he was fundamentally soft-hearted and tended to give away too much for free. He thought perhaps he needed "a little dose of sociopath-ness." I told him not to worry about it, because so long as he built something good enough to spread by word of mouth, he'd have a hyperlinear growth curve. If he was bad at extracting money from people, at worst this curve would be some constant multiple less than 1 of what it might have been. But a constant multiple of any curve is exactly the same shape. The numbers on the Y axis are smaller, but the curve is just as steep, and when anything grows at the rate of a successful startup, the Y axis will take care of itself. Some examples will make this clear. Suppose your company is making $1000 a month now, and you've made something...

...Being a leader is not limited to holding a high position in a team and being a leader does not only mean you have to be under certain organization with millions of followers rather one can still be a leader outside the perimeter of ones work area and one can even be a leader in ones own community. Success is always achieved together as a team but a team always needs a leader. Leadership is an ability and a talent that not everyone possesses and one has to be fair and righteous to be considered a good and effective leader. A true leader sets examples for his followers to follow. He does not tell his followers how to do things but tells them what to do and let them do it with the best of their ability. Leadership is an individual influencing a group to reach a certain goal. I discovered my ability to lead others when I was in my finance class. Being an accounting student, I am required to have some knowledge of finance. Before the semester started I heard from my senior friends that it’s a very hard class. Even after working hard students end up with ‘B’ grade. Still I took the class and after working hard I end up with “A” grade . I realized after studying the material first then student have a idea what to study and what not, so student end up doing bad because when they study the material for the first time they don’t give their full attention. So after the first test most of the students drop the class. One day in the class I asked one of my classmates if she interested...

...Prisons-Reentry One very important function of the corrections system is to assist inmates that are up for release from federal prison. Assistance is given by connecting these individuals to outside organizations for assistance. These organizations help to reduce recidivism rates. “The BOP contracts with residential reentry centers (RRCs), also known as halfway houses, to provide assistance to inmates who are nearing release. RRCs provide a safe, structured, supervised environment, as well as employment counseling, job placement, financial management assistance, and other programs and services. RRCs help inmates gradually rebuild their ties to the community and facilitate supervising ex-offenders' activities during this readjustment phase.” There are basically five general services provided by (RRCs.) (1) Accountability- Daily counts are conducted to all residence. A resident is only authorized to leave by sign out procedures, and only approved activities are accepted. These are for recreation, counseling, looking for employment and working. These approved activities are constantly monitored by RRC staff members. Individual’s that return to their RRC facility may be given a random drug/alcohol test. (2) RRC staff members help residence locate employment opportunities in their local communities. ” offenders are expected to be employed 40 hours/week within 15 calendar days after their arrival at the RRC.” (3) Residence are required to pay a fee that defrays the cost of their...

...The Help: Chapter 1 Set in Mississippi in the early 1960′s, “The Help” by Kathryn Stockett is told from three alternating viewpoints. One narrator is Eugenia “Skeeter” Phelan, a progressive young college graduate from an upper middle-class, white family who dreams of becoming a writer. Another narrator is Aibileen, a middle-aged African American woman who has been a maid her whole life and who has raised no less than 17 white children in the process. The last narrator is Minny, another African American maid in her thirties. Minny is Aibileen’s best friend, despite the fact that the two women could not be more different. All three women narrate around the same event: the publishing of Skeeter’s novel about working for white women. The story commences in August of 1962 in the kitchen of Elizabeth Leefolt. Aibileen is caring for Leefolt’s plump, two-year-old, Mae Mobley Leefolt, whom she calls Baby Girl. Aibileen's own son, Treelore, was killed months before she began working at the Leefolt residence. Treelore fell from a loading dock and was crushed under a tractor trailer. When the story opens it is the fourth Wednesday of the month, bridge club day, and Aibileen straightens up the house, manages Baby Girl, serves the women food, and overhears their conversation. The women discuss the upcoming Junior League Benefit, and Miss Hilly tells the women present, Elizabeth, Skeeter, and Hilly's mother, Miss Walter, about the Home Help Sanitation Initiative, a bill that requires a separate...

...The Help is a 2009 novel by American author Kathryn Stockett. The story is about African American maids working in white households in Jackson, Mississippi during the early 1960s. The novel is told from the point of view of three narrators: Aibileen Clark, a middle-aged African-American maid who has spent her life raising white children, and who has recently lost her only son; Minny Jackson, an African-American maid whose back-talk towards her employers results in her having to frequently change jobs, exacerbating her desperate need for work as well as her family's struggle with money; and Eugenia "Skeeter" Phelan, a young white woman and recent college graduate who, after moving back home, discovers that a maid that helped raise her since childhood has abruptly disappeared and her attempts to find her have been unsuccessful. The stories of the three women intertwine to explain how life in Jackson, Mississippi revolves around "the help", with complex relations of power, money, emotion, and intimacy tying together the white & black families of Jackson. A USA Today article called it one of 2009's "summer sleeper hits".[1] An early review in The New York Times notes Stockett's "affection and intimacy buried beneath even the most seemingly impersonal household connections" and says the book is a "button-pushing, soon to be wildly popular novel".[2] The Atlanta Journal-Constitution said of the book, "This heartbreaking story is a stunning debut from a gifted talent".[3] The...

A research question, which is more specific and focused than a general topic, is the question that you will answer in your paper. For example, if your general area of interest is Social Security, a potential research question might ask, “How might low-income families save more money under a reformed Social Security plan that includes personal retirement accounts?” As you develop a research question, keep in mind that you will research sources with both supporting and differing viewpoints. Do not select a narrow or one-sided issue that will limit your research; instead, develop a research question that lends itself to further exploration and debate. |What is your topic or area of interest? |My topic of interest is Drugs. | | | | | | | | | | |In what ways is this topic appropriate for a persuasive essay? |The way in which this topic is appropriate for a persuasive | | ...

...Salvation Army is an organization created by an evangelist from England named William Booth in 1852. He preached to the poor, hungry, homeless and destitute. William had the capability to convert people such as prostitutes and gamblers from non believers to believers. In 1872 he had about 1000 volunteers, and by 1885 numbers grew to 250,000 followers under the same Christian mission. The Army’s mission statement is to help people from bad habits and achieve their goals in life. The Salvation Army is a wonderful organization that can help a struggling person physically, mentally and spiritually. I have donated clothes before to the Salvation Army and Goodwill, but unfortunately never took time to devote a full day as a volunteer. I’m looking forward to serving their religious army in the future. The Salvation Army can benefit me in a couple of ways, personally I love networking with positive and influential people, taking in consideration that in life it’s not always what a person knows but also who they know! In a business aspect this organization can help me with more communication abilities, also give me the knowledge of the organization that can be passed down to someone with interest or in need of guidance. A career can also be made with the Salvation Army, Considering that I served in the United...

...Everyday people undertake physical journeys. They can be as simple as walking down the street or as complex as moving to a whole new place. Some are big and some are small, but they all have a unique significance for the individual. Journeys can be meaningful or unimportant but they all come with their own obstacles that may or may not be overcome. Journeys provide opportunities such as challenges and obstacles to help us discover ourselves and the world around us. One’s perspective and opinion can be changed along the way of a journey in a good or even bad sense. Many composers of text use their chosen medium, whether it be music, poetry, writing or art, to reveal their observations about physical journeys. Peter Skrzynecki uses his medium of poetry to convey his thought about physical journeys. Many of his poems suggest his idea that the journeying process never ends. In his poem A Drive in the Country he expresses his quest for freedom from his traumatic past and the hardships he has encountered along the way. In the song Nowhere Man written by John Lennon for The Beatles, it explains the journey of ‘Nowhere Man’ who doesn’t know where he is going or when his journey will end. A cartoon from the site www.cartoonchurch.com illustrates the struggle of a man trying to conquer a mountain but doubts he will ever be able to. All these text relate as they demonstrate that journeys can be difficult to complete and can also be never...
