Often sales of a new product grow rapidly at first and then level off with time. This is the case with the sales represented by
True [87]

Answer:

Here we have the function:

S(t) = 500 - 400*t^(-1)

Then the rate of change at the value t, will be:

S'(t) = dS(t)/dt

This differentiation will be:

S'(t) = -400/t^2

Then:

a) the rate of change at t = 1 is:

S'(1) =  -400/1^2 = -400

The rate of change after one year is -400

b) t = 10

S'(10) = -400/10^2 = -400/100 = -4

The rate of change after 10 years is -4, it reduced as the years passed, as expected.

<span>1. When you are paying a bill in full, said bill is completely paid off. In other words, the bill amount has been fulfilled by the consumer in a sort of payment.

It stands for c. annual percentage rate or the percentage that will be charged when a credit card is not paid in full by the due date each month. 3. When calculating interest accrued you should multiply the principal by the APR & number of months, then divide the number of months in a year (12). This will be the interest that the consumer has gained and must pay off to the lender.</span>
