Answer:
Step-by-step explanation:
I'm thinking you want to know the height of the ball on that 5th bounce, right? This is of the form
![y=a(b)^x](https://tex.z-dn.net/?f=y%3Da%28b%29%5Ex)
where a is the initial height and b is the decay factor. If the ball comes up to 2/3 of its height from the previous bounce, then b = 2/3 and our equation is
![y=30(\frac{2}{3})^x](https://tex.z-dn.net/?f=y%3D30%28%5Cfrac%7B2%7D%7B3%7D%29%5Ex)
If you want to know the height y of the 5th bounce x, sub in a 5 for x and solve for y:
and get that
y = 320/81 or as a decimal, 3.9506 feet
Answer:
I think that the answer would be C .
