Answer:
<u>Useful for this exercise:</u>
- Sum of interior angles of a triangle is 180°
- Straight angle is 180°
- Angle addition postulate
<u>Finding missing angles:</u>
- m∠1 = 180° - (57° + 72°) = 51°
- m∠2 = 90° - 72° = 18°
- m∠3 = 180° - 57° = 123°
- m∠4 = 180° - (18° + 123°) = 39°

The statement that is not true about the given trigonometric graph is; Option A: The vertical phase shift of y = 3 sin(-5x - π/2) - 6 is; π/5
<h3>How to Interpret Trigonometric Graphs?</h3>
Let us analyze the options;
A) For the give equation;
y = 3 sin(-5x - π/2) - 6
From the general equation given we can say that;
A = 3
B = 5
C = -π/2
D = -6
Thus, phase shift = C/B = -(π/2)/5
Phase Shift = -π/10.
Thus, option A is not correct.
B) Period = 2π/B
Thus; Period = 2π/5
Formula for frequency from period is;
Frequency = 1/period
Thus, it is correct that Period and frequency vary indirectly
C) As B gets bigger, the period gets smaller and the frequency gets greater. Thus, this option is correct
D) This statement is correct.

The maximum profit, as taught in calculus, can be determined when you equate the first derivative of the function to zero. So,
P' = 300 + 0
Hence, the maximum profit is 300.
I'm not sure about the vertices, though. Anyhow, I hope I was able to help you. Have a good day.
