To get the maximum height, we first determine the time at which this maximum height is attained by differentiating the given equation and equating the differential to zero.
h(t) = -0.2t² + 2t
Differentiating,
dh(t) = -(0.2)(2)t + 2 = 0
The value of t is equal to 5. Substituting this time to the original equation,
h(t) = -0.2(5²) + 2(5) = 5 ft
Thus, the maximum height is 5 ft and since it will take 5 seconds for it to reach the maximum height, the total time for it to reach the ground is 10 seconds.
Answers: maximum height = 5 ft
time to reach max height = 5 seconds
time it will reach the ground = 10 s
(a) Slope is rise over run, or change in y over change in x.
1 -> 3 ( 
)
2 -> 3 ( 
)
3 -> -1/3 ( 
)
(b) If a line is parallel, the slopes will be the same. If they are perpendicular, the slopes will be are negative reciprocals of one another. If they are neither, then their slopes don't match up in any way.
1 & 2 -> Parallel
1 & 3 -> Perpendicular
2 & 3 -> Perpendicular
Note - Since 1 & 2 are parallel, then both 1 and 2 will be perpendicular to 3!

Answer:
tbh that doesnt make sense the easiest way to et the first one is to do 955 divided by 90.
Step-by-step explanation:
Answer:
both Jenna and Mia got the same answer because the answer they got is correct but they used their own techniques to reach for the answer.
Mia's steps are time efficient enough by shortening the length of the sum and jumping steps...
Jenna is also correct in her own way, she wrote the full steps and explanation of the answer stepwise which is time consuming but cannot be wrong at the end throughout the steps. Even if she gets wrong she can quickly find the place of the mistake.
aarons height is 75 centimeters and Peter's is 1050 centimeters
