The equation modeling the height of the ball at time,t is given by h=-16t²+48t+6
<span>a. In how many seconds does the ball reach its maximum height?
Time taken for the ball to reach the maximum height will be given by:
h'(t)=-32t+48=0
finding the value of t we get:
32t=48
t=48/32
t=1.5 seconds
Thus the time taken for the ball to reach the maximum time is 1.5 seconds
b]</span><span> What is the ball’s maximum height?
The maximum height will be:
h(1.5)=-16(1.5)</span>²+48(1.5)+6
h(1.5)=42 fee
Answer:
Step-by-step explanation:
18.4 + 8w = 6(-4.6 + 9w)
18.4 + 8w = (-4.6 * 6 + 9w * 6)
18.4 + 8w = (-27.6 + 54w)
18.4 + 8w + -54w = -27.6 + 54w + -54w
18.4 + -46w = -27.6 + 54w + -54w
18.4 + -18.4 + -46w = -27.6 + -18.4
Combine like terms: 18.4 + -18.4 = 0.0
0.0 + -46w = -27.6 + -18.4
-46w = -27.6 + -18.4
-27.6 + -18.4 = -46
-46w = -46
w = 1
Simplifying
w = 1
