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.

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)

you have to wait a while to reward brainliest if only one person answers. if 2 people answer there should be a "mark brainliest" on their question.
