Write an Equation to Describe the Variation $\mathrm { q }$

question 95

Multiple Choice

Write an equation to describe the variation. Use k for the constant of proportionality.
- $\mathrm { q }$ varies directly as the square of $\mathrm { r }$ and inversely as $\mathrm { s }$ .

• A) \(\mathrm { q } = \frac { \mathrm { kr } ^ { 2 } } { \mathrm {~s} }\)
• B) \(\mathrm { q } = \mathrm { k } + \mathrm { r } ^ { 2 } - \mathrm { s } ^ { 2 }\)
• C) \(q = k ^ { 2 } s\)
• D) \(\mathrm { q } = \frac { \mathrm { ks } } { \mathrm { r } ^ { 2 } }\)
