Answer: The initial height of the ball is 12 feet.
Step-by-step explanation:
We have the function
, which models the height (in feet) of the ball after
seconds.
Then, as the height is in function of the time, we know that the ball is in the initial height when:

So, to find the initial height, you need to substitute
into the function:

Therefore, the initial height of the ball is 12 feet.
77,200 Is the answer take 386,000 and divide it by 5, 386,000/5=77,200 ;)
I think this is the answer
Answer:
b
Step-by-step explanation:
The length of the arc cannot be found without knowing some linear measure of the circle. None are given.
The measure of arc AB is twice that of angle APB, so is
2*108° = 216°.
The measure of arc APB is the difference between that and 360°, so is
360° -216° = 144°.
