Week Three Written Assignment
The steps that are being followed to solve quadratic equations that came from India, and the steps are: (a) Move the constant tern to the right side of the equation. (b) Multiply each term in the equation by four times the coefficient of the x2 term. (c) Square the coefficient of the original x term and add it to both sides of the equation. (d) Take the square root of both sides.

(e) Set the left side of the equation equal to the positive square root of the number on the right side and solve for x. (f) Set the left side of the equation equal to the negative square root of the number on the right side of the equation and solve for x. Let’s solve the equation (a): x2 –2x – 13 = 0

x2 – 2x = 13
4x2 – 8x = 52
4x2 – 8x – 13 = 52 – 13
4x2 – 8x – 13 = 39
2x – 13 = 39
2x – 13 = 39 2x – 13 = -39 2x = 26 2x – 13 = -26 x=13 x = -13 Now that the steps were used and were easy to follow and understand let’s apply them to equation (c): x2 + 12x – 64 = 0 x2 + 12x = 64

4x2 + 48x = 248
4x2 + 48x – 64 = 248 – 64
4x2 + 48x – 64 = 184
3x – 2 = 23
3x-2=23 3x – 2 = -23 3x = 21 3x = -21 x = 7 x = -7 This can be handy when you need to solve a quadratic equation in real life, and I could use it at work to find out the lowest price that certain steaks or roast can be sold at while the company is still making a nice profit to insure a raise in my future...

...This week’s assignment involves a method of solving a quadratic equation that purports to have originated from India. I shall use this methodology to complete (a) and (c), as assigned. I shall also complete an assignment involving a previously derived formula that may yield prime numbers . I shall conclude the assignment with a summary of what I have learned in completing the two assigned projects.
Project 1:
(a) Solve: x2 – 2x – 13 = 0 using the 6 step method described on page 331 of Mathematics in Our World.
1.) “Move the constant term to the right side of the equation.
x2 – 2x – 13 = 0
x2 – 2x = 13
2.) “Multiply each term in the equation by four times the coefficient of the x2 term.”:
x2 – 2x = 13
4x2 – 8x = 52
3.) “Square the coefficient of the original x term and add it to both sides of the equation.”:
4x2 – 8x = 52
4x2 – 8x + 4 = 52 + 4
4x2 – 8x + 4 = 56
4.) “Take the square root of both sides.”:
4x2 – 8x + 4 = 56
2x – 2 = +/- √56
5.) “Set the left side of the equation equal to the positive square root of the number on the right side and solve for x.”:
2x – 2 = √56
2x = √56 +2
x = (√56 +2)/2
x = 4.7416573867739414
6.) “Set the left side of the equation equal to the negative square root of the number on the right side of the equation and solve for x.”:
2x – 2 = -√56
2x = -√56 + 2
x = -(√56 +2)/2
x = -2.7416573867739414
For Project 1: (a), x = 4....

For this assignment I will be working 2 projects. For project #1 I will solve equations ( a) x² - 2x - 13 = 0 and ( c ) x² + 12x - 64 = 0 using steps a-f from page 379 Mathematics in Our World. For project #2, I selected five numbers consisting of 0, two even, and two odd. The projects actually comes from an interesting method for solving quadratic equations. The methods came from India (Bluman, 2011.) I will show my work by starting with Project 1 (A) and (C) and then move to Project 2.
For Project 1 (A) and (C), step (A) requires me to move the constant term to the right side of the equation.
(B) asks me to multiply each term in the equation by four times the coefficient of the x squared term.
(C) requires me to square the coefficient of the original x term and add it to both sides of the equation.
For (D) I must take the square root of both sides. (E) wants me to set the left side of the equation equal to the positive square root of the number on the right side and solve for x. Lastly, for (F) I will set the left side of equation equal to the negative square root of the number on the right side of the equation and solve for x. Below I will show you the work for each step for Project 1 (A) The I will do the same for (C).
Step (A) x² - 2x - 13 = 0 wants me to move the constant term to the right...

We have been learning how to develop our skills, in speaking, reading, and writing the English language. Did you know that when we were in math class, we were also learning how to speak, read, and write the language of mathematics? Mathematics uses numbers and number systems instead of the alphabet, but it's also a language: a language of patterns and symbols. Mathematics can help you recognize, understand, describe and identify changes in patterns.
Problem35.
A person hired a firm to build a CB radio tower. The firm charges $100 for labor for the first 10 feet. After that, the cost of the labor for each succeeding 10 feet is $25 more than the preceding 10 feet. That is, the next 10 feet will cost $125, the next 10 feet will cost $150, etc. How much will it cost to build a 90-foot tower?
Here is how we think about it:
We see that there is a new price every ten feet as they build the tower. After that the cost of the labor for each succeeding 10 feet is $25 more than the preceding 10 feet. That is, the next 10 feet will cost $125, the next 10 feet will cost $150, etc. How much will it cost to build a 90-foot tower?

1. The role of the financial system is to help match one persons savings with another person's investment.
2 types of market :
Stock market - represents ownership in a firm and is, therefore, a claim to the profits that the firm makes.
Bond Market - a certificate of indebtedness that specifies the obligations of the borrower to the holder of the bond.
2 types of intermediaries :
Banks - take deposits from people who want to save and use these deposits to make loans to people who want to save.
Mutual Fund - sells shares to the public and uses the proceeds to buy a selection, or portfolio of various stocks and bonds.
2. A government budget deficit is an excess of government spending over tax revenue.This affects investments and the economy because in order for the government to reduce the deficit they will need to cut programs and raise taxes. Higher taxes mean people spend less, invest less and the economy will decline due to lack of consumers spending money.
3. A benifit from insurance is the coverage of risk and accidents.
Adverse Selection : A high risk person is more likely to apply for insurance.
Moral Hazard - after people buy insurance they are more likely to be less cautious because the insurance company will pay for all the risk involved.
4. Efficient market hypothesis is the theory that asset prices reflect all publicly available...

As humans, most of us desire changing the world, hoping to make it more peaceful, prosperous, and more harmonious. Of course we all know that to change things, or help someone, or groups, etc, it takes money and usually a lot of it. But, with the right effective leadership skills and abilities, some people are able to change the lives of many. That is what Ellen DeGeneres has done with her skills, abilities, social status, and wealth.
Currently, Ellen is a host on The Ellen DeGeneres Show, which is a talk show that airs Monday through Friday. Ellen became a talk show host in 2003, where prior she played as a gay character on the sitcom, known as Ellen from 1994-1998, (Skerski, 2007). Ellen publicly announced her lesbian identity during a visit to the Oprah Winfrey show, which later assisted with the cancellation of the sitcom show, (Skerski, 2007). Being a lesbian celebrity is only one part of many parts of who Ellen is and the wonderful things she has and still is doing.
Ellen is known by her fans as humorous, talented, witty, but most of all giving, loving, and devoted to the things she finds important, like aiding in the fight against hunger. Ellen supports countless organizations, which she has been awarded for on numerous occasions. With Ellen conquering the negative aspects of the announcement of being gay,...

...WEEK 2 WrittenAssignment
I’m thinking no more than 1-2 paragraphs each for 3 & 4.
1. List the qualities (at least 6) that define life AND discuss how a single-celled organism, such as an Amoeba or a yeast cell, and a more complex one, such as a tree or a cat, matches up with each characteristic
1. Living things have cells.
2. Living things grow
3. Living things reproduce
4. Living things respond to stimuli
5. Living things use energy
6. Living things adapt to their environment
A single celled organism, such as an Amoeba, has a short life because of the heavy work load and exposure to elements on all four of its sides. An Amoeba operates on one cell, so it is a lot of work and cannot get very big with just one cell. Any injury to the cell can result in immediate death to the fragile organism. Yet, it is still a life because it IS a cell, and grows, can split in half and make a new amoeba, responds to the environment, uses energy to grow and can also adapt to their environments by living in both soil and water. They use their body to surround food and “eat” it. Some amoebas have learned to cover themselves in grains of sand to protect their small bodies. Trees, cats, and single cell organisms all need oxygen, have cells, grow and reproduce, respond to stimuli, use energy, and adapt to environment so they are all living things.
2. Choose 3 non-living things in addition to the “pet...

4. Buckingham Palace
A trip to Buckingham Palace is the ultimate tourist mainstay. Even the BFG paid a visit. During the summer months, the palace opens its doors to anyone craving a snoop, and we’ve been on a couple of occasions. It’s easy to spot the few Brits who take the tour – we’re the ones trying to suppress that involuntary smirk triggered by any annunciation from the Prince of Wales (who here provides an audio introduction to his once and future home). Only the most frenzied republican could remain undazzled by the opulent interiors, the Old Master paintings and Her Majesty’s secret dinner service.
3. HMS Belfast
Probably the only warship in the UK to share a birthday with Rudolf Nureyev (17 March 1938), the Belfast is a popular floating museum that gives you a cadet’s-eye view of a WWII Cruiser. The ship is pincered by competing attractions such as Tower Bridge and the London Dungeon. Yet it outguns them, both metaphorically and physically, with the depth of its displays and hands-on attitude. In particular, visitors are welcome to clamber around the pipes and ladders of the engine rooms with a refreshingly relaxed approach to health and safety. NB. You don’t want to do this in a skirt.

Never been? What? Shame on you. St Paul’s might be yet another tourist cliché, but it’s the spiritual heart...

Two-Variable Inequality

Two-Variable Inequality
We use inequalities when there is a range of possible answers for a situation. That’s what we are interested in when we study inequalities, possibilities. We can explore the possibilities of an inequality using a number line which is sufficient in simple situations, such as inequalities with just one variable. But in more complicated circumstances, like those with two variables, it’s more useful to add another dimension, and use a quadratic chart. In these cases, we use linear inequalities that can be written in the form of a linear equation. (Dugopolski, 2012).
Consider the following problem: “Maple rockers. Ozark Furniture Company can obtain at most 3000 board feet of maple lumber for making its classic and modern maple rocking chairs. A classic maple rocker requires 15 board feet of maple, and a modern rocker requires 12 board feet of maple. Write an inequality that limits the possible number of maple rockers of each type that can be made, and graph the inequality in the ﬁrst quadrant.” (Dugopolski, 2012).
First I must define what variables I will be using in my inequality. Let c=the number of classic maple rockers. Let m=the number of modern maple rockers.
Since each classic maple rocker requires 15 board feet of maple lumber, I will use 15c, and since each modern maple rocker requires 12 board feet of maple...
