Question A commonly used quadratic model for falling objects near Earth's surface is:
Distance fallen (in feet) at time t (in seconds): d(t) = 16t2
The rooftop of a 15-story building is 150 feet above the ground. How long does it
take a water balloon dropped from the rooftop to hit the ground?
The water balloon hits the ground in
seconds. If necessary, round your
answer to the nearest tenth.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

answer: you need the equation in the question so i can answer it
