A person invested $2,500 in an account growing at a rate allowing the money to doubleevery 11 years. How long, to the nearest tenth of a year would it take for the
value of the account to reach $3,800?

where is the triangle?

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.
