To find the angle measure of a circle, you first have to think about how a circle is 360 degrees around. If you're looking for the angle measure of 9 kids out of a total of 15, you'd have to divide 360 by 15 (which is 24) and then multiply that by the number of students you're counting, which is nine students. So, 9 times 24 is 216, which is your central angle

The answer to your question is B
Answer:
x = 2
Step-by-step explanation:
H(x) = 64x - 16x²
<u>Find the value of x when the ball reaches its maximum height.</u>
<u />
Since the largest degree in this equation is two, this function represents a parabola. We can find the maximum height of the ball at the vertex of the quadratic.
In H(x) = 64x - 16x², rearrange the powers from greatest to least:
Vertex: [-b/2a, f(-b/2a)]
Substitute a and b into the x-value of the vertex: -b/2a.
The vertex of the parabola is at x = 2, with a maximum height of H(2).
