Answer:

The constant of proportionality is 190.

Explanation:

A baby blue whale weighed 5520 pounds at birth.

After two days, the baby weighed 5710.

Means the weight gain is :
5710-5520=190 pounds

After 14 days, the baby weighed 8180 pounds.

Weight gain =
8180-5520=2660 pounds

So, per day gain =
(2660)/(14)= 190 pounds

Hence, the constant of proportionality is 190.

Answer:

Constant of proportionality is 190.

Step-by-step explanation:

To find proportionality constant we will find difference of weights after 2 days and at birth.


5710-5520=190

Now we will find difference of weights after 14 days and at birth. We will divide the difference by 14.


(8180-5520)/(14)


(2660)/(14)=190

We can see that weights are increasing at a constant rate of 190 pounds per day. Therefore, our constant of proportionality is 190.
