Solve the problem involving direct or inverse variation.
-If x varies inversely as v, and x = 36 when v = 9, find x when v = 81.
A) x = 4
B) x = 9
C) x = 81
D) x = 36

Question

Quizplus · Accepted Answer

Since x varies inversely as v, the relationship can be described by the equation x = k/v, where k is a constant. Given x = 36 when v = 9, we can find k by substituting these values into the equation: 36 = k/9, which gives k = 324. To find x when v = 81, substitute k = 324 and v = 81 into the equation: x = 324/81, which simplifies to x = 4.
