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
The missing factor would be (n+2)... If you wanted to understand it, you simply solve 4n^2+9n+2 which gives you (4n+1)(n+2).
Answer:
9cm
Step-by-step explanation:
I guessed until I got the right answer
26 = orchestra
11 + 13 = 24 = choir
26 x 2 = 52 = band
52 + 24 + 26 = 102 people in all the following on top.
Hope this helped!

Answer: $180
4ft + 5ft + 4ft + 5ft = 18ft
18 x 10 = 180
