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)
All you would do is multiply .9 by 20
.9*20=18
90% of 20 is 18
0 hundreds<span> is equal to 9000. To find the number of 10's in 9000, simply divide them 9000/10 = 900. Comments; Report</span>
Given:
y = sinx
Required:
To find the range.
Explanation:
The graph of the sine function is as follows:
We can observe from the graph that the values of y lie between -1 to 1.
So the range of the sinx function is [-1, 1].
Final Answer:
The range of sinx function = [-1, 1].
Answer:
$0.96
Step-by-step explanation:
To find the unit price is to find the price of 1 meter.
9m = $8.64
1 m = 8.64 ÷ 9 = $0.96
