Y varies directly as x and inversely as the square of z. Y=34 when x=68 and z=2. Find y when x =81 and z=3.
Added by Jonathan M.
Step 1
Given that Y varies directly as x and inversely as the square of z, we have the equation Y = k * x / z^2. Plugging in the values, we get 34 = k * 68 / 2^2. Solving for k, we get k = 34 * 4 / 68 = 2. Show more…
