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 it will reach the ground = 10 s
Answer:
Parallel.
Step-by-step explanation:
Let's find the slope of each line.
One through the points (3,2) and (6,8):-
Slope = rise / run = (8-2)/(6-3)
= 6/3 = 2
The other line:-
Slope = (6-2)(2-0)
= 4/2 = 2
The slopes are the same so the 2 lines are parallel.
