The distance a baseball travels when a player hits the ball varies directly with the speed with which the player swings the bat. the graph below shows the distances a baseball travels (in feet) and the speed of the swing (in miles per hour).

based on the graph, which relationship exists between the speed of the swing and the distance the ball travels?

a the distance is 0.1 times the swing speed.

b the distance is 0.2 times the swing speed.

c the distance is 5 times the swing speed.

d the distance is 10 times the swing speed.

answer:

the correct answer is c

step-by-step explanation:

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! : )
