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)

Answer:
Circumference of the circle = 100.53 in.
Step-by-step explanation:
Circumference of a circle is given by the formula,
Circumference = 2πr
Radius of the circle 'r' = 16 in.
Therefore, circumference of the circle with radius 16 in will be,
C = 2π(16)
C = 32π
C = 100.53 in.
