Write an equation that expresses the following relationship.

Question

W varies directly with U and inversely with the square root of D, in your equation, use k as the constant of proportionality.

Answer 1

If W varies directly, then W = kU (both go up or down together, but at different rates determined by the value of k. W also varies inversely with √D, so they move in opposite directions (as √D increases, W decreases and v.v). So the overall relationship of the variables is W = kU/√D.

Answer 2

(W)(√D) = (U)k
