Step 1
Given that y is inversely proportional to the square root of x, we have the equation y = k / sqrt(x). Substitute y = 15 and x = 7 into the equation: 15 = k / sqrt(7) 15 = k / sqrt(7) k = 15 * sqrt(7) k = 15 * sqrt(7) Show more…

Write an equation to describe each variation. Use $k$ for the constant of proportionality. See Examples I through $7 .$ $y$ varies directly as $x$ and inversely as $p^{2}$
