Question

The quantities x and y are proportional. Find the constant of proportionality r in the equation y = ex

Answer 1

Here, e is the proportionality constant.

Explanation:

Two quantities P and q are said to in proportion if and only if they have equivalent fraction in each case.

or,
`(P)/(Q)  = k` for each value of P and Q.

Here, k is called the Proportionality Constant.

Now here given: x and y are in proportion.

also, y = ex

⇒
`(y)/(x)  = e`

So, here e is the proportionality constant.
