Solve Combined Variation Problems
-$P$ varies jointly as $R$ and $S$ and inversely as the square root of $a$.
A) $\mathrm { P } = \frac { \mathrm { kRS } } { \sqrt { \mathrm { a } } }$
B) $P = \frac { k R } { S \sqrt { a } }$
C) $\mathrm { P } = \frac { \mathrm { k } ( \mathrm { R } + \mathrm { S } ) } { \sqrt { \mathrm { a } } }$
D) $P = \frac { R S } { k \sqrt { a } }$

Question

Quizplus · Accepted Answer

The correct formula for $P$ is $P = \frac { kRS } { \sqrt { a } }$ because it shows $P$ varying jointly with $R$ and $S$ (indicated by the product $RS$) and inversely with the square root of $a$ (indicated by the division by $\sqrt{a}$).
