waecmaths question:
If $p\propto \frac{1}{q}$ which of the following is true
Option A:
$q\propto {{p}^{2}}$
Option B:
$q\propto \frac{1}{{{q}^{2}}}$
Option C:
$q\propto \sqrt{p}$
Option D:
$q\propto \frac{1}{p}$
waecmaths solution:
$\begin{align} & p\propto \frac{1}{q} \\ & p=\frac{k}{q}\text{ }\{k=constant proportionality\} \\ & q=\frac{k}{p} \\ & q\propto \frac{1}{p} \\\end{align}$
