Ababy blue whale weighed 5520 pounds at birth. after two days, the baby weighed 5710. after 14 days, the baby weighed 8180 pounds. is there a constant of proportionality?

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.

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

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

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)

step-by-step explanation:

$3,200 x 7.25% = $3,200 x .0725 = $232 interest monthly

$232 monthly x 12 annual = $2, 784
