Answer:
the answer is what ever you want it to be
Step-by-step explanation:

9pi/8 = 8pi/8 + pi/8 = pi + pi/8
12 + pi - 9pi/8 = 12 + pi - pi - pi/8
Given Sarah could rum 800m in 3 minutes and 20 seconds = 3*60+20 = 200 seconds when she was in year 8.
Where as she could run 800m in 2 minutes 44 seconds = 2*60+44=164 seconds.
Percentage improvement in her time = (difference in time/ original time) * 100
Hence there is an improvement of 18% in her time.
It will hit the ground after 3.499 seconds.
To solve this you first have to find the value of h(0) in this equation. That is the height from which it was dropped.
You can input any of the points into the equation and solve for the missing part. You will get 60 for the height.
The use the quadratic formula to see that it reaches the ground after 3.499 seconds.
Answer:
1 and 12/25
its over 100 percent, that's where the 1 comes from. the 48 that's left would be 48/100, which is then simplified to 24/50, which is simplified one more time to 1 12/25
