I really need the answers to these. Please show your work. Thank you so much! If Michael invests $2000 in the bank at a rate of 5.5% for 6 years how much interest will he make?

Kelsey takes out a loan for $6000 to start a business after high school. The bank charges her 8% interest for the loan. After 5 years how much interest will be added on to the loan?

Jessie invests $3345 in the stock market. Over the 3 years she has this invested she gets an average return of 7.8%. How much will her investment be worth after the 3 years?

Taylor has just won $4,250 from the 50/50 at the Sea Dog's game and decides to invest all of it. If he makes $1275 with a 5% interest rate, how long must he have had the money invested?

At what rate would you need to invest $12000 and make $2880 after 8 years?

Morgan has an investment worth $130,000 dollars after 20 years. If his original investment was for $50,000 what must the interest rate have been?

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! : )

answer: what are the following choices

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
