 # Math 133 Unit 3 Individual Project 2b

MATH133 Unit 3 – Individual Project -B

1) Solve the following algebraically. Trial and error is not an appropriate method of solution. You must show all your work.

Learn how to type math roots and fractions by clicking on link in the assignment list. Alternately, you may type 3x as cuberoot(x) and show raising to the nth power as ^n, like x 3 is typed x^3 or x3/2 is typed x^(3/2).

a) 1/4 = 3 – (2x-1)/(x+2)

b) x^(3/2) =125

c) cuberoot(x) – 4 = 2

2) Solve algebraically and check your potential solutions:

a) sqrt(x+20) – x = 0

b) 5 – 2/(x-6) = (10 – 2x)/(x – 6)

c) What potential solution did you obtain? Explain why this is this not a solution.

3) The following function computes the cost, C (in millions of dollars), of implementing a city recycling project when x percent of the citizens participate.
C(x) = 1.4x / (100 – x)

a) Using this model, find the cost if 60% of the citizens participate?

b) Using this model, determine the percentage of participation that can be expected if \$4 million is spent on this recycling project. Set up an equation and solve algebraically. Round to the nearest whole percent.

4) a) If y = sqrt(x) - 2, fill in the following table for x = 0,1,2,3,4. Round to three decimal places where necessary.

see attached file

b) Explain why no negative values are chosen as values to substitute in for x.

c) Graph in MS Excel or another web-based graphing utility and paste your graph here. Read the information in the assignments list to learn more about how to graph in MS Excel.
