Answer:
[tex]d=\frac{kw}{p^2 }[/tex]
where k is the constant of proportionality.
Step-by-step explanation:
The original question is
d varies directly with w and inversely with the square of p
k is always the constant of proportionality
d varies directly with x so we multiply 'w' in the numerator
for inversely proportional we put the square of p in the denominator
so the equation becomes
[tex]d=\frac{kw}{p^2 }[/tex]
where k is the constant of proportionality.
