Find the length of the diagonal of the rectangle. Round your answer to the nearest tenth. The height of the rectangle is 12 meter. The length is 15 meters

Rounded value: 19.2m

Step-by-step explanation:

Length=15m

Height=12m

Diagonal²=length²+height²=

15²+12²=225+144=369m²

Diagonal=sqrt(369)=19.21m

Rounded value: 19.2m

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! : )
