16) Jacob is performing a trick shot for the dudes at Dude Perfect. He stands on a hill and throws a football in the air and it knocks an apple off Mr. H's head. The height h, in feet of the ball can be modeled by
the equation:
h= -16t2 + 48 x+ 64, where t is time, in seconds, the ball is in the air.
You must show ALL work for credit. Show how you solved it and show the work required to find the maximum height.
A When will the ball hit the ground?
B. What is the maximum height the ball reaches?
C. Is Mr. H injured by the ball?

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

c.)

step-by-step explanation:

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
