c as a function of d:
Step-by-step explanation:
We are given the following in the question:
c is inversely proportional to the square of d.
When c = 6, d = 3.
Plugging the values, we get,
Thus, the constant of proportionality is 54.
c as a function of d can be written as:
We have to find value of c when d = 7.
Putting values, we get,
is the required value of c.
