The quantity n varies jointly with the product of z and the square of the sum of x and yWhen n is 18, x = 2, y = 1, and z = 3What is the constant of variation?

The constant of variation is .

Step-by-step explanation:

Given : The quantity n varies jointly with the product of z and the square of the sum of x and y When n is 18, x = 2, y = 1, and z = 3.

To find : What is the constant of variation?

Solution :

The quantity n varies jointly with the product of z and the square of the sum of x and y,

i.e.

Where, k is the constant of variation.

Substitute n=18, x = 2, y = 1, and z = 3,

Therefore, the constant of variation is .
