Answer:
V = 314.16
Step-by-step explanation:
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
Mean is the sum of values divided by the count of values.
The sum of values is 1,235.
There are 9 values.
1235/9 = 137.22
4x+5=13
Start by subtracting 5 from both sides:
4x+5-5=13-5
4x=8
Divide both sides by 4 to isolate x
x=2
Answer:
= -27a^3+108a^2-144a+64
Step-by-step explanation:
Simplify:
=64-144a+108a^2-27a^3
=64+-144a+108a^2+-27a^3
Answer
= -27a^3+108a^2-144a+64
