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: 150% increase
Step-by-step explanation:
percent of increase: new/old × 100%-100%
--------------
new/this month: 20 puppies
old/last month: 8 puppies
new/old×100%-100%
=20/8×100%-100%
=2.5×100%-100%
=250% -100%
=150% increase
Hope this helps!! :)

Answer:
angle 1=94 degree
Step-by-step explanation:
-x + 106=5x + 34 (they are alternate interior angles)
106-34=5x+x
72=6x
72/6=x
12=x
substitute the value of x in 5x + 34
5*12 + 34
60+34
94
Now,
angle 1 =5x +134 ( they are vertically opposite angles)
angle 1=94 degree
