Variation

d varies directly with the cube of w and inversely with p;
use k as the constant of proportionality.
Can anyone help me solve this?

Re: Variation

They are saying write as an equation expressing the relationship

d varies directly with the cube of w and inversely with p;
use k as the constant of proportionality.

Re: Variation



I'm not sure how much you know or don't know, so bear with me if I say things that you are already aware of.

First, the 3 superscript on the w means it is cubed and since d varies directly with w cubed, w cubed is in the numerator on the other side of the equals sign. On the other hand, since d varies inversely with p, then p is in the denominator. The constant of proportionality k is assumed to be in the numerator.

If you have any questions, please reply.

Re: Variation

Ok thank you, very well explained.
Are you copying your symbols from another website if you don't mind my asking?
