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
SA= 2LW + 2LH + 2WH
Substituting for the values, SA = 900 cm^2
Answer:
A = $2,240.00
(I = A - P = $240.00)
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year.
Solving our equation:
A = 2000(1 + (0.03 × 4)) = 2240
A = $2,240.00
The total amount accrued, principal plus interest, from simple interest on a principal of $2,000.00 at a rate of 3% per year for 4 years is $2,240.00.
Answer:
180 minutes so 3 hours
