A human body that is performing light work generates about 650 BTUs of body heat per hour. If a room that is 10 ft × 12 ft × 9 ft is being painted by 3 people, how many BTUs per cubic foot do they produce in 2 hours? (to the nearest tenth)

100.335283 m2

Step-by-step explanation: L x W x H

30

step-by-step explanation:

times by times

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! : )
