Question

Use the following to answer questions :
y = 190 sin 
-Identify the amplitude (A).
A) |A| = 8 
B) |A| = -8 
C) |A| = 70 
D) |A| = -70

Quizplus · Accepted Answer

The formula for finding the amplitude of a sine function is |A| = |y|max/2. 
In this case, the maximum value of y is 190, so:
|A| = 190/2 = 95
Therefore, the correct answer is C, with an amplitude of 70 being the closest option.
