Question

Write an equation that expresses the following relationship.

p varies directly with the square of d and inversely with u
In your equation, use k as the constant of proportionality.

Answer 1

Explanation:

p = kd/u

p varies directly with d, p=md

p varies inversely with u, p=n/u

put them together

p=kd/u

as d goes up, p goes up. as u goes up, p goes down
