Short Answer

Find an equation of variation for the given situation.
-y aries jointy as x and p and inverely as the square of s, and $y = \frac { 1 } { 2 }$ when x=1, p=1, and s=2 .
A) $y = \frac { 4 x ^ { 2 } p } { s ^ { 2 } }$
B) $y = \frac { 2 x p } { s ^ { 2 } }$
C) $y = \frac { 6 x p ^ { 2 } } { s }$
D) $y = 7 x p s ^ { 2 }$
