Answer:
3 seconds
Step-by-step explanation:
We have to give us the following function h (t) = - 16 * t ^ 2 + 48 * t + 3
Now, they tell us that the height is 3 feet, therefore replacing that value we have left:
3 = -16 * t ^ 2 + 48 * t + 3, operating cancels 3. And it would be:
-16 * t ^ 2 + 48 * t = 0
Removing common factor -16 * t, it would be:
(-16 * t) * (t - 3) = 0
We have two solutions:
-16 * t = 0 ---> t = 0
t - 3 = 0 ---> t = 3
Because the time cannot be 0 seconds, the time it would take the ball in the air is 3 seconds.
Answer: 2598.8
Solution:
Step one: 49•12.80 = 627.2 (the amount that people under 16 payed)
Step two: 155-49=106 (the amount of people over 16)
Step three: 106•18.60=1971.6 (the amount of money that people over 16 payed)
Step four: 627.2+1971.6=2598.8 (the total amount of collected money from tickets)
