<span>A ball is thrown into the air with an upward velocity of 36 ft/s. Its height h in feet after t seconds is given by the function h = −16t2 + 36t + 5. In how many seconds does the ball reach its maximum height? Round to the nearest hundredth if necessary. What is the ball’s maximum height?
A. 2.25 s; 5 ft
B. 1.13 s; 25.25 ft
C. 1.13 s; 27.5 ft
D. 1.13 s; 65.75 ft <====

Answer:
The function h(x) is decreasing on the interval (3, ∞).
Step-by-step explanation:
Please take a look at the attached image.
You will see a graph of the given function h(x) = -2
. The function is decreasing.
The function starts at 3 and starts to go towards negative infinity on the x-axis. Therefore the function is decreasing on the interval (3, ∞).
It would be the first one because it says that there are 4 times as many red roses as pink roses and so that would be represented r=4p
Hope this helps! Good luck!
Percent decrease { (original number - new number) / original number....x 100
percent decrease : (75 - 25) / 75....x 100
50 / 75...x 100
0.666 x 100
66.6% decrease <==not sure if u need it rounded ?
In total there are 20 students and only 6 read 1 book. So the answer would be 6/20
