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

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, 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

⇒

So, here e is the proportionality constant.

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
