Arthur makes $216 each week writing a column for a newspaper. he recently wrote his first book and earns $7 for each copy sold. last week, he made $517 from the newspaper and sales of his book combined. which of the following accurately describes arthur's profit from last week and number of copies of his book that were sold? 216 - 7c = 517; 41 copies 216 - 7c = 517; 45 copies 216 + 7c = 517; 46 copies 216 + 7c = 517; 43 copies

a) 32pie square meters

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! : )
