Write an equation that expresses the following relationship. u varies directly with the square of p and inversely with d

In your equation, use k as the constant of proportionality.

Given:

u varies directly with the square of p and inversely with d.

To find:

The equation for the given situation.

Solution:

If y is directly proportional to x, then

If y is inversely proportional to x, then

It is given that u varies directly with the square of p and inversely with d. So,

It can be written as:

Where, k is the constant of proportionality.

Therefore, the required equation is .

option: d is correct
