The eqaution i use for this is:


(cross multiply)
(25.83)(100) = (x)(49.5) (multipy)
2583 = 49.5x (divide by 49.5 on both sides)
52.181818182 = x

Answer:
A
Step-by-step explanation:
Given a sinusoidal function (sine function or cos function) in the form
y = A Cos (Bx), we can say that A is the amplitude.
<em>Amplitude defines the function's maximum and minimum.</em>
The maximum of this form of function is A and the minimum is -A.
The function given is y = -Cos(8x), so A is -1
Thus, maximum value is 1 and minimum value is -1.
Correct answer is A
