...Solving Proportions MAT 222 Roberta Bledsoe July 21, 2013 Solving Proportions When having to solve for proportions we have a process to go through. First we must use the Extreme-Means property. The first problem, example A., is the word problem about bear population. Putting the word problem into an equation we get b/50 = 100/2. We must solve the equation to find what b will equal. Then we have a second problem, example B., which is Y-1/x+3 = -3/4. We will solve example B. until we get to the linear equation format or an extraneous solution. Both examples of proportions will be solved in the same process though the problems themselves seem very different. A. To estimate the size of the bear population on the Keweenaw Peninsula, conservationists captured, tagged, and released 50 bears. One year later, a random sample of 100 bears included only 2 tagged bears. What is the conservationist's estimate of the size of the bear population? B=bear population The variable b will be used to identify the bears in population b/50 = 100/2 I used the ratio equation to solve for b. (2)(b)=(50)(100) I crossed multiplied the two fractions. We multiply the two extremes 2 and b. Then we multiply our means 50 and 100. 2b=5000 B=5000/2 To isolate the b I divided 2 on both sides. B=2500 After diving the 5000 by 2 we see that b then equals 2500. B. Y-1/x+3 = -3/4 This is the proportion will be solved into linear equation format. -3(y-1)= 4(x+3) The...

...Composition and Inverse Jessica Cantu MAT 222 Week5 Final Assignment John Gomillion June 13, 2014 Composition and Inverse Functions can be very useful because they give us the option to change up an expression by using different values. These values and functions can help a person or a company be successful and wise. Functions also extend independent (x) and dependent (y) variables by graphing in the coordinate plane. This is very helpful because it creates a visual demonstration of the relationship. The following functions will be used in the required problems. f(x) = 2x + 5 g(x) = x2 – 3 h(x) = 7 – x 3 The first task is to compute (f – h)(4). (f – h)(4) = f(4) – h(4) Following the rules of composition, each function can be calculated separately and then subtracted. f(4) = 2(4) + 5 The x is replaced with the 4 from the first problem. f(4) = 8 + 5 Order of operations is used to evaluate the function. f(4) = 13 h(4) = (7 – 4)/3 Here the same process is used for h(4) and f(4). h(4) = 3/3 h(4) = 1 (f – h)(4) = 13 – 1 (f – h)(4) = 12 This is the solution after substituting...

...Early Childhood Education LEARNING CENTRES “HONEY BEES READING CENTRE” Introduction What are Learning Centres? The term Learning Centres refers to designated areas of the classroom where students congregate in small groups to accomplish given learning tasks. Typically, students can work independently in these centres, sometimes while the teacher works with a small reading group. Examples of learning centres may include: listening to audio cassettes, playing educational games on the computer, practicing handwriting, writing/editing written works, reading silently, playing imaginatively in the puppet centre, and playing math games with manipulatives. Student work in a given learning centre for a certain amount of time, then rotate to the next one when time is up. Teachers will need to spend a significant amount of time training students on how to behave during centre time, as well as modelling how to complete each of the learning centre activities. This will assure that learning centre time is productive, relatively quiet, and organized. AGE GROUP OF CENTRE AND THE MAIN CHARACTERISTICS OF CHILDREN IN AGE GROUP Four and five year-olds are the age group for which the ‘Honey Bees Reading Centre’ is planned. Children in this age range display several characteristics which can be categorized as cognitive, physical, psychosocial and moral. Cognitively * Enjoy stories and can retell them * Are fascinated by words and silly sounds * Have large vocabulary...

...November 2, 2009, was to correct a possible incursion of an incorrect or out-of-place front driver's side floor mat into the foot pedal well, which can cause pedal entrapment. The second recall, on January 21, 2010, was begun after some crashes were shown not to have been caused by floor mat incursion. In March 2010, at the time of the recall, Toyota was unsure of the cause behind a spate of cars that would speed up without the driver's help. Hybrid’s breaking systems: Prius owners have reported that brakes momentarily fail when driving in icy or slippery conditions, or over potholes. Normally the anti-lock braking system engages and disengages many times a second as the system reacts to the slipping tyres. But - as Toyota puts it - some drivers have complained of "inconsistent brake feel" during slow and steady braking on some surfaces when ABS is activated.The solution involves an upgrade of the software in the braking system, which should take less than an hour and will be carried out for free by official Toyota service centres. Toyota stresses that the cars are still safe to drive and the brakes will stop the car. US safety authorities, however, have said they have received reports of accidents, including a small number of reported injuries.There have been no reports of accidents in Europe. The Japanese auto giant recalled 2.17 million vehicles because of carpet and floor mat flaws that could jam gas pedals. Toyota has recalled more than 12 million vehicles...

...A set of real numbers used in place of a variable (x, y, z, etc…) is called the domain. Real numbers are used in place of variables to assist in the functionality of the equations. This excludes any real number that causes the denominator to be zero. The reason a denominator cannot be zero is because when we divide the denominator with the numerator, you cannot divide by zero. You can’t have a value that is undefined. The two problems that I was assigned are as follows: 1-x2x 2b-22b2-8 In my first expression, I start by transforming it to a rational expression (1-x) (1+x). Since each set contains terms that are perfect squares, I will factor using the difference of squares formula: a²-b²= (a-b) (a+b). In my problem, a = x and gives me: (-x+1) (x+1). Next, I reorder the polynomial from left to right starting with highest order term which is x = 0 As stated above, the domain of an expression is all real numbers except when the expression is undefined. Type equation here. (1-x)(1+x)x I simply the FOIL expression by multiplying and combining like terms giving me: 1-x2x I divide each term in the numerator and denominator. Then I reduce the term by removing the factor of x giving me the expression: 1x-x The Domain (D) is the set of all Real Numbers, written in set notation that would look like this: D = {x| x ∈ ℜ} The final answer is: x≠0 Undefined written in set notation. D={x|x ∈ R, x ≠ 0} In my second expression, I will start by factoring...

...of my home. My home is a rental student apartment which is located on the 8th floor of Medical Plaza, the University of Utah. Although it is not my real home, I still want to call it “my home.” My apartment is small and crowded but comfortable. My apartment is a two-bedroom apartment, which means I have a roommate. My apartment has a very clean living room, a little kitchen and a small bathroom. First, as you walk into the apartment, the white wall and white ceiling make the apartment more bright and clean. Then you can see there is a large round wooden brown desk in the center of the room. There are five leather brown chairs around the desk. There is a very large French window which almost occupies the whole north wall. The brown floor mat also makes the room more comfortable and warm. When the night is coming, you can see the very good vista through the large window. I really like seating beside the desk and have a cup of coffee, and I enjoy the wonderful time. Although the living room is not big, it is comfortable and lovely. Secondly, I will introduce my little kitchen and bathroom. The little kitchen has a large white refrigerator that always has good food and a big oven and microwave oven. Over the oven, you can find there is a clean and whiter range hoods.

...get cool. Such issues are easier to control when doing your workouts at home although they still need proper planning. In other words, at home workouts are efficient to plan for when compared to outdoors exercises. For instance, at home workouts put you closer to the kitchen, to the shower and your closet. If you explicitly consider proximity to these vital necessities, you will find that they offer you with profound technical advantages. This article gives you the final tips that are a perfect fit for everyone doing their workouts at home. 1. Buy yourself a mat The first point worth considering before doing the at home workouts is the platform on which you will be exercising on. Although the space at your home may be restrictive, you should make sure that the platform that you are using is ideal for your body fitness. Although the floor surface is probably covered with a carpet or a mat, it is important to get a mat specifically for your workout. This ensures that your body hygiene is not compromised. Additionally, it improves the cleanliness of your room because nobody likes the smell of stale sweat that drips on the carpet during...

...Problem & Exercise Chapter 8 3. A report is meant for reading and information, so if a report is not properly put together then these things can happen: * listed with no page numbers then they can be shuffled and get out of order * putting the headings of the columns on every page (if not it is information overload & you will lose you place) * having incorrect information/data * missing one of the who, what, when, or where (software error) * data errors The consequences to these errors are: * the wrong decisions can be made * the data can given or received can be wrong * the outputs are wrong If the analyst can notice most of the errors as he is working on them so that it may be corrected then this can help keep the project of the report going without too many complications. Prototyping is very helpful when working on reports because the analyst is able to structure and refine the report before it is viewed by the mass majority without the consequences of errors. 4. The date does not specify when the report was generated; it does not give a revision date or code for any prior report versions, does not provide any meaningful information, there is not any page number listed, the spacing of the report information does not seem to be in place.

...Abstract Kabir Das : Literature and Communication Literature is the mirror of society and it is the reflection of the age, which it belongs to. Literature of any age and era shows the prevalent trend of the period when it was created and connects at its best to that era. The uniqueness of the literature of Saint Kabir is that it transcends all boundaries and limitations of time and place. In spite of the fact that his literature belongs to the period of 15th century it is still relevant, remembered, quoted and discussed with passion and fervor not only among the connoisseurs of art and literature but also among common man and youth. This article is an attempt to throw light on the various dimensions of Kabir Das’s literature and how it is still effectively communicated and in turn is used for effective communication. This paper contemplates on the varied aspects of kabir’s literature. Kabir’s literature is known for elements of mysticism, spirituality, concept of love, his objectivity in imparting moral education, his attack on vices of human behavior, hypocrisy and materialistic attitude. All these aspects are dominantly reflected in his literary works and are still relevant in today’s social scenarios which are well communicated in the form of his well remembered ‘Dohas’ and poetry. Hence, it is concluded that Kabir’s literature, in spite of being so old and classical is timeless and well applicable and connected with today’s era. His ‘Dohas’ makes...
