The maximum height of the volleyball is 12.25 feet.
Step-by-step explanation:
The height of the volleyball, h(t), is modeled by this equation, where t represents the time, in seconds, after that ball was set :
....(1)
The volleyball reaches its maximum height after 0.625 seconds.
For maximum height,
Put ![\dfrac{dh}{dt}=0](https://tex.z-dn.net/?f=%5Cdfrac%7Bdh%7D%7Bdt%7D%3D0)
Now put t = 0.625 in equation (1)
![h(t)=-16(0.625)^2+20(0.625)+6\\\\h(t)=12.25\ \text{feet}](https://tex.z-dn.net/?f=h%28t%29%3D-16%280.625%29%5E2%2B20%280.625%29%2B6%5C%5C%5C%5Ch%28t%29%3D12.25%5C%20%5Ctext%7Bfeet%7D)
So, the maximum height of the volleyball is 12.25 feet.
