Step-by-step explanation:
Answer: 5.22 seconds
<u>Step-by-step explanation:</u>
t represents time and y represents the height.
Since we want to know when the ball hits the ground, find t when y = 0
Ball 1 starts at a height of 109 --> h = 109
0 = -16t² + 109
16t² = 109



t = 5.22

Answer:

Step-by-step explanation:
The equation of the line shown can be expressed in the slope-intercept formula as 
Let's find m = slope, and b = y-intercept.
Using two points on the line, (0, 1) and (1½, 0),

y-intercept, b is where the line intercepts the y-axis = 1.
To create an equation for the line, substitute m = -⅔, b = 1 in
.
✅The equation would be:
