Step-by-step explanation:
Hello ;
y= -6
The intersection points of the equations represents; C: The time when the height of the ball and the bird are the same.
We are given;
The height of the baseball over time:
h = -16t² + 65t
The height of the bird over time:
h = 8t + 20
The intersection point will be the value of t when; 8t + 20 = -16t² + 65
Rearranging gives;
16t² + 8t - 45 = 0
Using online quadratic equation calculator gives us;
t = -1.94 s or t = 1.44 s
Now, since both equations measure height vs time, it means that the points of intersection tell us the time when the height of the ball and the bird are the same.
