Brad needs to fill his daughter's sandbox that is 5 feet by 10 feet. He wants to buy sand bags to fill the sand 1 feet deep. He compares the prices found for san at two different stores. STORE X: 45 lbs for $4.50

STORE Y : 60 lbs for $4

Part A

What is the unit rate for Store X.

Part B

What is the unit rate for Store Y.

Part C

Which store has the better price?

Part D

Brad find online that it takes 100 pounds of sand to fill 1 cubic foot. Using the better store price, compute how much it will cost him to purchase enough sand to fill the sandbox. Use the V= L x W x H to determine your answer.

step-by-step explanation:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
