Answer:
The volleyball travel high enough to clear the top of the net.
Step-by-step explanation:
The height of a volleyball, h, in feet, is given by h = −16t² + 11t + 5.5, where t is the number of seconds after it has been hit by a player.
Now, for h = 7.3 feet, we can write
7.3 = - 16t² + 11t + 5.5
⇒ 16t² - 11y + 1.8 = 0
Using the quadratic formula we get,

⇒ 
⇒ t = 0.27 or t = 0.42
Therefore, for the two real positive values of t the volleyball travel high enough to clear the top of the net. (Answer)
Answer:
900 feet squared
Step-by-step explanation:
15 x 10 x 6 = 900
5

5 x 8 = 40
6 x 1 = 6
40 / 6 = 6

= 6 2/3
