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.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

step-by-step explanation:
