Answer:
s + 65.99 divided by 2 (the last one)
Step-by-step explanation:
With this problem you just look at the graph and answer it that way. Look at where the heart rate is at its max and then look at the beginning and end, the shape of the graph. Then answer the question.
5/8 as a decimal would be 5/8 times 100/x because if you found the equivilent fraction you would be able to multiply it by the upside-down-fraction and get 1 for example 2/4 =1/2 if you multiply 4/2 with 1/2 you would get 4/4 or 1
so 5/8 times 100/x =500/8x=1
then use long division to solve 62.5/100=62.5%
The height when the ball drops would be 0, so plug in 0 for h(t):
0 = -16t^2 + 500
Then you would solve for t, which in this case would equal to the time it takes to land.
-500 = -16t^2
t = 5.59, so it would take about 5.6 seconds to reach the ground.
