Mrs. Sherman is a dance teacher whose students are going to have a recital. She is comparing two companies' prices for filming the recital and producing DVDs. Shontal's Productions charges $2 per DVD, plus $74 to come and film the recital. Springdale Media charges $70 to film, plus $3 per DVD. To decide which company to use, Mrs. Sherman determines the number of DVDs that would make the two options equivalent in terms of cost. How much would each option cost? How many DVDs would that be?

A. $82

B. 4

Step-by-step explanation:

Let n be the unknown number

Cost of each production :

40 minutes

step-by-step explanation:

add the time and multiply by 2

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! : )
