Question

Write an equation that expresses the following relationship.u varies jointly with p and d and inversely with wIn your equation, use k as the constant of proportionality.

Answer 1

`u=k\cdot(p\cdot d)/(w)`

Step-by-step explanation:

If a varies jointly with b, we write the equation

a = kb

If a varies inversely with b, we write the equation

a = k/b

So, if u varies jointly with p and d and inversely with w, the equation is

`u=k\cdot(p\cdot d)/(w)`
