Answer:
The ball travel horizontally 37 feet before it hits the ground
Step-by-step explanation:
we have
![A(x)=-0.02x^2+0.6x+5](https://tex.z-dn.net/?f=A%28x%29%3D-0.02x%5E2%2B0.6x%2B5)
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
![-0.02x^2+0.6x+5=0](https://tex.z-dn.net/?f=-0.02x%5E2%2B0.6x%2B5%3D0)
solve the quadratic equation
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
![-0.02x^2+0.6x+5=0](https://tex.z-dn.net/?f=-0.02x%5E2%2B0.6x%2B5%3D0)
so
substitute in the formula
therefore
The ball travel horizontally 37 feet before it hits the ground
You cannot solve one equation with 3 variables. In this case you have an infinity of results. <span />
