Hi im doing this test right now and what is the answer lol
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
The correct answer is 8×(-6) - 8×3/4.
Simplifying this problem is the same as the problem 8× - 6 3/4, not 8× -5 1/4.
Answer:
z=1
Step-by-step explanation:
8(z+3)=32
Multiply 8 into the parenthesis.
8z+24=32
Subtract 24 both sides.
8z=8
Divide 8 both sides.
z=1
