Wheel A is 56 inches. The diameter of wheel B is 35 inches. Suppose each wheel makes 15 revolutions. Find the distance between the wheels after
they have made these 15 revolutions.
Use 22/7
as an approximation for π.

18 in

Step-by-step explanation:

990 inches

Step-by-step explanation:

I will ASSUME that BOTH wheel dimensions given are diameters and the wheels begin at the same point and are moving in the same direction.

circumference is πD

15π56 - 15π35 = 15π(56 - 35) = 15π21 = 15(22/7)21 = 990 inches

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! : )
