-Find the constant of variation.
A) 1.125
B) 11.25
C) 112.5
D) 0.1125

Quizplus · Accepted Answer

The formula for direct and inverse variation is given by A = k(B/C^2), where k is the constant of variation.

Substituting the given values, we get:

93.75 = k(20/1.2^2)

Simplifying this equation, we get:

k = 93.75 * (1.2^2/20) = 11.25

Therefore, the constant of variation is 11.25, which corresponds to choice letter B.
