Question

Write an equation that expresses the relationship. Solve the equation for C.D varies jointly as C and H.Write an equation that expresses the relationship.D=

Answer 1

C = D/kH

Step-by-step explanation:

If D varies jointly as C and H

This can be expressed as;

`D\propto\text{ CH}`

If we remove the proportionality sign, we will introduce the proportonality constant k. This can then be express as;

`D\text{ = kCH}`

Hence an equation that expresses the relationship is D = kCH

To get C, we will divide both sides by kH

D/kH = kCH/kH

D/kH = C

Hence the expression for C = D/kH
