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:
400 feet squared
Step-by-step explanation:
First you divide 6 by 3
you get 20
then you times 20 by its self
and you get 400 feet squared
Answer: The average person doesn't live 1 million hours. 1 million hour is 114 year. That is much more than 78 years. 1 million ours is too much. You would need 683280 to make it 78 years.
Let us assume capacity of large bottle = 1000 ml.
And capacity of each small bottle = 25 ml.
Reaming milliliters in large bottle = 250 milliliters.
Number of bottles = x bottles.
Total capacity of large bottle - capacity of a small bottle × number of bottles > Reamining milliliters in large bottle.
Therefore, we can setup an inequality.
1000 - 25 × x > 250.
1000 -25x >250.
