Question

24 varies inversely with 6^2
Write a general formula to describe the variation.

Answer 1

• y = 864/x

------------------------------

Inverse variation is:

• y = k/x, where k- constant

Use the given values and find the value of k:

• 24 = k/6²
• 24 = k/36
• k = 24*36
• k = 864

General formula is:

• y = 864/x
