w varies directly with the square of u and inversely with d use k as the constant of porportionality

Question

Just need help putting this into equation form

 

Answer 1

If "y varies directly with x," then y = kx.

 

If "y varies jointly with x and z," then y = kxz.

 

If "w varies directly with the square of u," then w = ku².

 

If "w varies inversely with d," then w = k/d.
