The position of the ball when it is at its highest point is 121
<h3>Polynomial function</h3>
Given the polynomial function expressed as y = -1/250(x - 175)^2 + 121,
The velocity of the ball at the maximum point is zero. Hence;
dy/dx = -1/125(x-175)
Equating to zero;
0 = -1/125(x - 175)
x = 175
Substitute into the function to get the maximum height
y = -1/250(175 - 175)^2 + 121,
y = 121
Hence the position of the ball when it is at its highest point is 121

Answer: 67.2°
Step-by-step explanation:
To find angle C, we have to use cosine rule. Therefore,
12² = 8² + 10² - 2 × 8 × 10 × cosC
C = 82.8°
The bearing of A from C will be
= 150° - 82.8°
= 67.2°.
