Answer:
Step-by-step explanation:
Known facts:
- the ball dropped from a height of 64 feet
- function

First question:
- the ball hits the ground when h(t) = 0, thus we get the equation

So the ball hits the ground in 2s
Second question
- to find how long it takes the ball to fall 36 feet, we must set h(t) = 64 - 36 = 28

So the ball hits the ground in 1.5s
Hope that helps!
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -15 ± √((15)^2 - 4(2)(4)) ] / ( 2(2) )
x = [-15 ± √(225 - (32) ) ] / ( 4 )
x = [-15 ± √(193) ] / ( 4)
x = [-15 ± sqrt(193) ] / ( 4 )
x = -15/4 ± sqrt(193)/4
The answers are -15/4 + sqrt(193)/4 and -15/4 - sqrt(193)/4.

<h3>I'll teach you how to solve x= 12 - y, 2x + 3y = 29</h3>
------------------------------------------------------------
x= 12 - y, 2x + 3y = 29
Substitute x=12-y:
[2(12-y)+3y=29]
Isolate y for 2(12-y)+3y=29:
2(12-y)+3y=29= y= 5
Substitute y=5:
x=12-5
12-5= 7
x=7
Your Answer Is (C) x=7, y=5
