What is 50/8 as a mixed number

The ball travel horizontally 37 feet before it hits the ground

Step-by-step explanation:

we have

where

x ----> is the horizontal distance in feet

A --->  is the altitude of the ball, in feet.

we know that

When the ball hit the ground, the altitude of the ball is equal to zero

so

For A(x)=0

solve the quadratic equation

The formula to solve a quadratic equation of the form

is equal to

in this problem we have

so

substitute in the formula

therefore

The ball travel horizontally 37 feet before it hits the ground
