An investment of $80,000 was made by a business club. The investment was split into three parts and tasted for one year. The first part of the investment earned 8% interest, the second 0%, and the third 0% Total interest from the investments was $6840. The interest from the first investment was 6 times the interest from the second. Find the amounts of the three parts of the investment.

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

what is the answer?

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! : )

using pemdas, (order of operations) you'll see the answer is 24.
