A ball is rolling down a slope and continuously picks up speed. Suppose the function f(x) = 1.1(1.13) describes the speed of the ball in inches per minute. How fast will the ball be rolling in 18 minutes? Round the answer to the nearest whole number. The ball will be rolling at a rate of about __?__ inches per minute after 18 minutes.

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

it has to have an angle of 90 degrees
