Answer:
You calculate the distance between the angle and the arch and you can solve your answer.
Step-by-step explanation:
For example... An arc measure is an angle the arc makes at the center of a circle, whereas the arc length is the span along the arc. This angle measure can be in radians or degrees, and we can easily convert between each with the formula π radians = 180° π r a d I a n s = 180 ° .
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.
