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:
B (-1, 1.5)
Step-by-step explanation:
Add the x coordinates together and divide by 2: (-4 + 2) = -2/2 = -1.
The only option with (-1) as an x-coordinate is B, and that is the answer.
The first step to solving this equation would be to how much they made for every apiece. To do this we must multiply the cost of the $80 apiece by how much they sold, as well multiplying the $45 apiece by how many they sold. And also the $60 apiece by the how many they sold.
$80 apiece × 356 tickets = ?
$60 apiece × 275 tickets = ?
$45 apiece × 369 tickets = ?
Now we must solve our equations.
$80 apiece × 356 tickets = $28,480
$60 apiece × 275 tickets = $16,500
$45 apiece × 369 tickets = $16,605
The next step would be to add up all the total costs of each apiece.
$28,480 + $16,500 + $16,605 = $61,585
So our answer is...
The box office took in a total of $61,585
