Answer:
The maximum height of the ball is 28.2 yards.
Step-by-step explanation:
When we have a quadratic equation in the following format:

The maximum value happens when

The maximum value will be 
In this problem, we have that:

So


The maximum height is:

The maximum height of the ball is 28.2 yards.
That's a cubic graph. Anything with that sideways 's' shape is a cubic graph.
Answer:
When x = 64, y = 80.
Step-by-step explanation:
Since the origanal value was 8 and now it´s 64, lets divide to see how much was multiplied. Then lets multipliy it with that number.
64 / 8 = 8
Soo..8 x 10 = 80.
When x = 64, y = 80.
You could divide 9/20 to get 0.45
