Answer:
10.84
Step-by-step explanation:
First we multiply
1.4+(3.2×2.95)
1.4+9.44=
=10.84
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
Add 8π to both sides
x-8π+8π=π+8π
x=π+8π
x=9π
Find each sum.
1. 56+ (-56) = 0
The number series 1, 2, 3, 4, 55, 56. Therefore, 1596 is the sum of positive integers.
