Answer:

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 :

h(t)=-16t^2+20t+6 ....(1)

The volleyball reaches its maximum height after 0.625 seconds.

For maximum height,

Put \dfrac{dh}{dt}=0

Now put t = 0.625 in equation (1)

h(t)=-16(0.625)^2+20(0.625)+6\\\\h(t)=12.25\ \text{feet}

So, the maximum height of the volleyball is 12.25 feet.

Is the distance a baseball travels in the air after being hit a discrete random​ variable, a continuous random​ variable, or not
LuckyWell [14K]

Answer: a continuous random​ variable

Step-by-step explanation:

<u><em>Can you count the distance it traveled?</em></u> You can't, so it couldn't be discrete because you can count discrete variables.

<u><em>Can you measure the distance it traveled? </em></u>You sure can, that makes it a continuous random variable.

<u><em>Do you know the exact distance it's going to travel?</em></u><u> </u>You won't, therefore it's a random variable since you don't know the value beforehand.
