Suppose the Sunglasses Hut Company has a profit function given by P(q) = -0.02q^2 + 5q - 20, where q is the number of thousands of pairs of sunglasses sold and produced, and P(q) is the total profit, in thousands of dollars, from selling and producing q pairs of sunglasses.

A) How many pairs of sunglasses (in thousands) should be sold to maximize profits? (If necessary, round your answer to three decimal places.)
Answer: _____________ thousand pairs of sunglasses need to be sold.

B) What are the actual maximum profits (in thousands) that can be expected? (If necessary, round your answer to three decimal places.)
Answer: _____________ thousand dollars of maximum profits can be expected.

Write each polynomial in the form p(x) = d(x)q(x) + r(x). You may use synthetic division wherever applicable.

A.) x^2 + x + 1; d(x) = x - 1
B.) 4x^3 - x + 4; d(x) = x - 2
C.) x^6 - 3x^5 + x^4 + 2x^3 + x^2 - x + 1; d(x) = x^2 + 2

Use synthetic division to find the function values:

D.) f(x) = -2x^4 - 10x^3 - 3x + 10; find f(-1) and f(2)
E.) f(x) = x^4 - 2x^2 + 1; find f(1/2)

Determine whether q(x) is a factor of p(x) and justify your answer.

F.) p(x) = x^3 - 7x + 6; q(x) = x - 3
G.) p(x) = 3x^3 - 48x - 4x^2 + 64; q(x) = x + 4
