Answer:
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.

Answer:
How do you find the equilibrium price with a supply and demand function?
To determine the equilibrium price, do the following.
Set quantity demanded equal to quantity supplied:
Add 50P to both sides of the equation. You get.
Add 100 to both sides of the equation. You get.
Divide both sides of the equation by 200. You get P equals $2.00 per box. This is the equilibrium price.
