Two identical rubber balls are dropped from different heights. Ball 1 is dropped from a height of 16 feet, and the ball 2 is dropped from a height of 144 feet. Write and graph a function for the height of each ball. Then use the graphs to tell when each ball will reach the ground.

Two identical rubber balls are dropped from different heights. Ball 1 is dropped from a height of 181 feet, and ball 2 is dropped from a height of 238 feet. Write a function for the height of each ball.

h1(t) = -16t^2 + 181

h2(t) = -16t^2 + 238

When does ball 1 reach the ground? Round to the nearest hundredth. seconds

Solve: -16t^2+181 = 0

-16t^2 = -181

t^2 = 11.3125

t = 3.3634 seconds

When does ball 2 reach the ground? Round to the nearest hundredth. seconds

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
