Answer:
the ball hit the ground at
Step-by-step explanation:
we have
This is the equation of a vertical parabola open downward
The vertex is a maximum
we know that
The x-intercept of the function is the value of t when the value of h(t) is equal to zero
The ball hit the ground when h(t) is equal to zero
equate the function to zero and solve for t
Factor the leading coefficient
The solutions are
therefore
the ball hit the ground at
When the ball hits the groung h(t) = 0
Then solve the equation for t
- 16t^2 + 96 t = 0
Divide by -16
t^2 - 6t = 0
t(t-6) = 0
t =0 is when the ball is kicked off
t = 6 is the answer.

The solution to the equation 3x + 1 = 10 is x = 3.
To solve the equation 3x + 1 = 10, follow these steps:
Step 1: Get the variable term (3x) by itself by subtracting 1 from both sides of the equation.
3x + 1 - 1 = 10 - 1
3x = 9
Step 2: Isolate the variable by dividing both sides of the equation by the coefficient of x, which is 3.
3x/3 = 9/3
x = 3
So, the solution to the equation is x = 3.

Answer:
It would take 90 hours to fill the pool.
Step-by-step explanation:
There is a mistake in the question so it is corrected below:
An inlet pipe on a swimming pool can be used to fill the pool in 40 hours. The drain pipe can be used to empty the pool in 45 hours. If the pool is 1/4 filled and then the inlet pipe and drain pipe are opened, how many more hours would it take to fill the pool?
Now, to find the hours would it take to fill the 1/4 pool.
Let the hours it take to fill the pool be
A swimming pool can be used to fill the pool in 40 hours.
So, the rate of filling the pool = .
As, given the drain pipe can be used to empty the pool in 45 hours.
Thus, the rate of draining the pool = .
According to question:
Using cross multiplication:
Dividing both sides by 20 we get:
Therefore, it would take 90 hours to fill the pool.
