Answer: A:3 rolls B: $38.67
Step-by-step explanation:
1. Convert all units to the same value (feet to inches, as the opposite gives fractions)
2. Use new equation and multiply the said new variable (84*3 & 96*3)
3. The new total should amount to the total area (540)
4. Divide found area by 12 to convert back into feet (45)
5. Divide the feet by feet per roll (3)

Answer:
After 1.5 second of throwing the ball will reach a maximum height of 44 ft.
Step-by-step explanation:
The height in feet of a ball after t seconds of throwing is given by the function
h = - 16t² + 48t + 8 .......... (1)
Now, condition for maximum height is
{Differentiating equation (1) with respect to t}
⇒
seconds.
Now, from equation (1) we get
h(max) = - 16(1.5)² + 48(1.5) + 8 = 44 ft.
Therefore, after 1.5 seconds of throwing the ball will reach a maximum height of 44 ft. (Answer)
