Walter owns 60 books now. he plans to buy 10 books every month. which recursive formula gives the number of books walter will have in any month in the future? next = now + 10, starting at 60 next = 60 × now + 10 next = now + 60, starting at 60 next = now + 10, starting at 10 next = now × 10, starting at 60 nextreset

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.
