Write a Variation Model $Q = \frac { k x ^ { 2 } } { y ^ { 3 } }$

question 86

Multiple Choice

Write a variation model. Use k as the constant of variation. Q is directly proportional to the square of x and inversely proportional to the cube of y.

• A) \(Q = \frac { k x ^ { 2 } } { y ^ { 3 } }\)
• B) \(Q = \frac { k x ^ { 2 } } { \sqrt [ 3 ] { y } }\)
• C) \(Q = k x ^ { 2 } y ^ { 3 }\)
• D) \(Q = k x ^ { 2 } + \frac { k } { y ^ { 3 } }\)
