Answer:
0.125 seconds.
Step-by-step explanation:
We have been given that the height of a ball above the ground as a function of time is given by the function , where h is the height of the ball in feet and t is the time in seconds.
We can see that our given equation is a downward opening parabola as its leading coefficient is negative. The maximum point will be vertex of parabola.
To find the time, when the ball would be at its maximum height, we need to find the x-coordinate of vertex.
Using formula , we will find the x-coordinate of vertex of parabola as:
Therefore, the ball will be at a maximum height after 0.125 seconds.
Sector C is 35% of the circle, so it will be 35% of the degrees of a full circle, which is 360.
Multiplying something by .35 gives you 35% of the number, so do that with 360.
360 x .35 = 126
The angle is 126º.
Hope this helps!
