Answer 1

Problem Solving:-

1. Find the equation of variation where a varies jointly as b and c, and a = 36 when b = 3 and c = 4.

Solution:-

`\sf{a = kbc}`

`\sf\rightarrow{36= k(3)(4)}`

`\sf\rightarrow{K= (36)/(12)}`

`\sf\rightarrow{K={\color{magenta}{3}}}`

Answer:-

• Therefore, the required equation of variations is a = 3bc.
