The exponential function n = 3.93 * 1.34d gives the approximate u. s. population, in millions, d decades after 1790. (the formula is valid only up to 1860.) (a) what is the yearly growth factor?

We have the following formula:

n = 3.93 * 1.34 ^ d

With the following variable:

d = decades after 1790

The growth factor of the population for each decade is:

k = 1.34

Which means that the population grows 34% every decade.

For each year we have:

1.34 ^ (1/10)

=1.03

The annual growth factor is:

k = 1.03

Answer:

the yearly growth factor is:

k = 1.03
