Mowing the Grass Four friends volunteered to mow the grass around their neighbor's house. They decided to split the job up into
weeks instead of everyone mowing the grass on the same day. On week 1, Jay mows the grass at a rate of 25%
every 30 minutes. On week 2, Amy mows the grass at a rate of 3 of the grass every 30 minutes. Week 3, Ken
mows at a rate of 0.3 of the grass, every 30 minutes. It takes Brittany 2.5 hours to mow all of the grass on week
4. Determine how long it takes each person to cut all the grass. Who was the fastest?

360/29

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! : )

i believe a. 12x≥120 is the answer

the ratios are reciprocals im positive

step-by-step explanation:

they are all positive numbers so it wouldn't be the other ones
