The length of a shadow of a building is 27 m. The distance from the top of the building to the tip of the shadow is 31 m. Find the height of the building. If necessary, round your answer to the nearest tenth.

its like a triangle

shadow is the base

31 meters is the hypotenuse

a^2 + b^2 = c^2

27^2 + b^2 = 31^2

b = square root of 232 which is 15.2315462117

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! : )
