Apost is driven into the ground. the first strike drives the post 30 inches into the ground. the next strikes drives the post 27 more inches into the ground. assume these distances from a geometric sequence. what is the total distance (to the nearest inch) the post is driven into the ground after 8 strikes?

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
