Dan is fertilizing his garden. the garden is in shape of a rectangle l. its lenth is 15 feets and its width is 13 feet. suppose each bag of fertilizer covers 39 square feet. how many bags will need to cover the garden?

A = l*w

A = 15*13

A = 195 ft^2

Each bag covers 39 ft^2

195/39

5

He will need 5 bags

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! : )
