Answer to Problem 14PPE
Explanation of Solution
Given Information:
The variable y varies inversely with x. The value of y is 3.5 when x is 2.2 .
Calculation:
Given that the variable y varies inversely with x. So we have
Here k is the constant of proportionality.
Also given that the value of y is 3.5 when x is 2.2 . So, on substituting values of x and y in above equation (i), we get
So, with this value of k , above equation (i) becomes
