Rena transferred a balance of $2150 to a new credit card at the beginning of the year. the card offered an introductory apr of 5.9% for the first 3 months and a standard apr of 30.2% thereafter. if the card compounds interest monthly, which of these expressions represents rena's balance at the end of the year? (assume that rena will make no payments or new purchases during the year, and ignore any possible late payment fees.) a.(2150)(1+00.59/12)^3(1+0.302/12)^ 12 b.(2150)(1+00.59/3)^12(1+0.302/9)^1 2 c.(2150)(1+00.59/12)^3(1+0.302/12)^ 9 d.(2150)(1+00.59/3)^9(1+0.302/9)^3

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000

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! : )
