The Environment

Environmental and wildlife preservation ensures future generations will have available resources and can enjoy the beauty of Earth. On the other hand, some of the damage humans have already done to the environment is expensive and time consuming to eradicate.

What is the cost to remove 75% of the pollutant? 6000 6000 6000
C = --------------- = --------------- = ------------ = $120 200 – 2 * 75 200 – 150 50

b. What is the cost to remove 90% of the pollutant? 6000 6000 6000
C = ------------------ = ------------------- = ----------- = $ 300 200 – 2 * 90 200 – 180 20

c. What is the cost to remove 99% of the pollutant? 6000 6000 6000
C = ------------------- = ------------------ = -------------- = $ 3,000 200 – 2 * 99 200 – 198 2 d. For what value is this equation undefined? The equation is undefined for X = 100%

e. Do the answers to sections a. through d. match your expectations? Explain why or why not.

It is expected that the amount of the pollutant would increase per each percentage. The percentages get higher for each problem therefore making the pollutant higher as well. I thought that they would be higher as the…...

...may be a positive or negative response. While writing this paper, I think it is a good idea to learn to give honest opinions about the subject and also provide a good amount of detailing to help describe whether this teacher did or did not have a good impression on me. It is very important to say whether I was able to learn how to be a better teacher and what the teacher did that I could possibly use in the future. While analyzing and going through the process of this assignment it is helping realize how to become a better teacher as well. I would also like to get more comfortable and experience on using this template of the paper. Memories Of A Teacher My teacher, Mr. G, used many different instructional techniques and approaches to his lessons. Mr. G had taught me math for three years in a row, so I think that I have a good grasp on his approaches to the lessons that he would teach. He would assign many homework assignments, as well as in-class assignments, which helped me and other students understand and get practice with the lesson that we were learning. I think that with math having a lot of homework is a good thing. In my mind, the only way to learn how to do math is plenty of practice. The more you practice, the easier it will be. Mr. G would also have the students do some math problems on the chalk board or smart board to show the class and go over the corrections with the whole class so that everyone would understand the problem. Playing “racing” games also......

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......

...reasons. It normally takes about eleven years to become a doctor, four years of college, four years of medical school, and three years of working in the hospital. If you think about it that is a long time to actually get started in your career but it definitely pays off. If your wanting to be a doctor you should want to help people and be ready to study very much. Your probably wondering by now how being a doctor relates to mathematics. Doctors have to know how to use the metric system when weighing or taking the height of patients. They mainly have to know pounds and kilograms. Doctors write many prescriptions everyday so they have to know what to give to patients mainly depending on their weight. For example, when prescribing an antibiotic called amoxicillin it is 45mg/kg twice a day so if a child weighs twenty two pounds they will take 225mg of amoxicillin twice a day for however many days the doctor thinks it is necessary. Doctors also have to know how to use math to determine how much of an IV to give the patient. Knowing the body mass index formula helps them to determine if their patients are overweight or underweight so that they can help them and give them directions on how to solve that. There are many people who think of becoming a doctor but do not realize that hardships it takes to get there and all the hard work they have to go through in the process. “There are some who do have a strong determination of entering the medical field, but after......

...Diana Garza 1-16-12 Reflection The ideas Stein presents on problem saving and just math in general are that everyone has a different way of saving their own math problems. For explains when you’re doing a math problem you submit all kinds of different numbers into a data or formula till something works or maybe it’s impossible to come up with a solution. For math in general he talks about how math is so big and its due in large measure to the wide variety of situations how it can sit for a long time without being unexamined. Waiting for someone comes along to find a totally unexpected use for it. Just like has work he couldn’t figure it out and someone else found a use for it and now everyone uses it for their banking account. For myself this made me think about how math isn’t always going to have a solution. To any math problem I come across have to come with a clear mind and ready to understand it carefully. If I don’t understand or having hard time taking a small break will help a lot. The guidelines for problem solving will help me a lot to take it step by step instead of trying to do it all at once. Just like the introduction said the impossible takes forever. The things that surprised me are that I didn’t realize how much math can be used in music and how someone who was trying to find something else came to the discovery that he find toe. What may people were trying to find before Feynmsn....

Math come to geometry, your opinion may vary. This class introduces a lot of new topics, which can be challenging, and take lots of practice outside of school if you do not pay attention or do your math homework. I strongly advise you to do your math homework everyday, not for just a grade, but it also helps you when it comes time for quizzes and tests. She rarely checks homework, but when she does, she will not tell you. It is also a great review for tests and quizzes. Ms.Hull’s tests and quizzes are not the easiest things you will take. The quizzes take new concepts and apply to the quiz. Also, her tests are usually always hard. It is a good idea to practice new concepts and review old ones from previous units, so you can get a good grade on the tests. I also advise you to be organized throughout the year. Organization is the key to success especially in math class. Tool kits are an extremely helpful resource to use. There are going to be a lot of conjectures and theorems that will be new, and it would be hard to just memorize them. My overall geometry year was not exactly the way I hoped it would turn out. It was extremely had, and it moves at a very quick pace, so keeping up was hard for me personally. If I could have done something differently, it would have been practicing math more often. Each concept was hard, and I did not have anytime to review it, because I have a lot of honors classes which require a lot of work too. The key to being successful in this......

...Jasmine Petersen Dr. Abdeljabbar MAT 1111 April 23, 2014 Algebra is one of the most important subjects someone can learn. It is a subject that transfers into daily life. A lot of people do not realize that they are using algebra. Algebra can be anything from calculating the amount of money you’ve spent on your grocery shopping, designing structural plans for a building, and keeping track of the calories you have in your diet. Our professor told us that in every subject, we use math. My major is chemistry and mathematics is used widely in chemistry as well as all other sciences. Mathematical calculations are absolutely necessary to explore important concepts in chemistry. You’ll need to convert things from one unit to another. For example, you need to convert 12 inches to feet. Also, we use simple arithmetic to balance equations. A lot of things I’ve had learned from this course and one of them was that we use Math for everyday life. I’ve also learned many ways how to solve equations such as linear, quadratic, exponential, and logarithmic equations. All the material that we did learn was all easy to learn and understand. I believe that the instructor did a good job explaining on how to solve problems. If my friend was asking me how to determine the differences between the equation of the ellipse and the equation of the hyperbola, I would first give he or she the definition of the two words ellipse and hyperbola. An ellipse is a set of all points in a plane such that the......

...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......

Students feel jubilant and rewarded when correct solution is achieved. “The harder the struggle, the sweeter the victory is a common expression. This study was brought about when Mathematics, especially problem solving processes, Mathematics interest and Mathematics aptitude. Problem solving, which the National Council for Teacher in Mathematics (NCTM) 1980’s widely heralded statement in its agenda for action and problem solving has been the theme of the council. Knowledge and skills of Mathematics problem solving is believed to help school goers solve problems in their day to day of existence. The ancient claimed “Mathematics is the queen of Knowledge,” hence it is only right to say that Mathematics enhanced students understanding of the important principles in math, that is, as a cooperative and never ending process. Mathematics also made them exert more effort in improving their achievement and inspire them in relating Mathematics and applications for the solution of human problems. There are many ways of solving problems. The one presented by Polya – a Mathematician of the 18th Century. According to Polya, to solve problems in Mathematics, a student must follow certain steps of processes. Polya’s steps for solving Mathematics problems are; (a) Understand the Problem, (b) Devise a Plan, (c) Carry out the Plan, and (d) Look Back (McCoy 1994). Due to this vision, the......

Many people know that the weight of an object varies on different planets, but did you know that the weight of an object on Earth also varies according to the elevation of the object? In particular, the weight of an object follows this equation: , where C is a constant, and r is the distance that the object is from the center of Earth. a. Solve the equation for r. b. Suppose that an object is 100 pounds when it is at sea level. Find the value of C that makes the equation true. (Sea level is 3,963 miles from the center of the Earth.) c.

...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.
