After a baseball is hit, the height h (in feet) of the ball above the ground t seconds after it is hit can be approximated by the equation h = -16t² + 64t + 3. determine how long it will take for the ball to hit the ground. round your answer to the nearest.. it is due tomorrow

The ball will take 4.05 seconds to hit the ground.

Step-by-step explanation:

we have

This is a quadratic equation (vertical parabola) open down

The vertex is a maximum

we know that

The ball hit the ground when h=0

Solve the quadratic equation

For h=0

The formula to solve a quadratic equation of the form

is equal to

in this problem we have

so

substitute in the formula  

 ---> the time cannot be a negative number

therefore

The ball will take 4.05 seconds to hit the ground.

mean, 40.6

step-by-step explanation:

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"
