Question

Answer 1

Given that

and

are inversely proportional, we can start by writing out that relationship as the equation

, where

is the constant of proportionality. To find the constant of proportionality,we substitute

and

into the equation

. After getting the value of

, we use this to find the equation for

. In part b) of the question, we are asked to find the value of

when

, we simply insert

for

in our equation identified in part a).
