Eloise got the following scores on the first five quizzes of the semester: 6,9,7,8,9. there is one more quiz left. what score must eloise get on the last quiz to have a mean quiz score of 8? explain how you found your answer

9

Step-by-step explanation:

when u add her past five scored together, you get 39. your equation would be

39 + x

        = 8

6

you multiply both sides by 6 and get

39+x = 48

subtract 39 from both sides to get 9

d≈7.07in

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! : )
