Question

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

Answer 1

Answer:

Here,  e is the proportionality constant.

Step-by-step explanation:

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

or, $\frac{P}{Q}  = k$ 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

⇒$\frac{y}{x}  = e$

So, here e is the proportionality constant.
