-$y$ varies jointly as $x$ and $p$ and inversely as the square of $s$, and $y = \frac { 9 } { 2 }$ when $x = 1 , p = 9$, and $s = 4$.
A) $y = \frac { 12x p ^ { 2 } } { s }$
B) $y = \frac { 32 x ^ { 2 } p } { s ^ { 2 } }$
C) $y = \frac { 8 x p } { s ^ { 2 } }$
D) $\mathrm { y } = 9 \mathrm { xps } ^ { 2 }$

The equation of variation where $y$ varies jointly as $x$ and $p$ and inversely as the square of $s$ is $y = k\frac{xp}{s^2}$, where $k$ is the constant of variation. Substituting the given values $y = \frac{9}{2}$, $x = 1$, $p = 9$, and $s = 4$ into the equation, we can solve for $k$ and find that $k = 8$, making the correct equation $y = \frac{8xp}{s^2}$.
