Write a model for the statement. V varies jointly as h and the $\text { ffth power }$ of r
A) $V = k h r ^ { 5 }$
B) $V = \frac { 1 } { k h r ^ { 5 } }$
C) $V = 5 k h r$
D) $V = k h + k r ^ { 5 }$
E) $V = \frac { k h } { r ^ { 5 } }$

Question

Quizplus · Accepted Answer

When two quantities vary jointly with a third quantity raised to a power, the formula is of the form V = khr^n where n is the power and k is a constant of proportionality. In this statement, V varies jointly with h and r^5, so the formula would be V = khr^5. Therefore, the best choice is A.
