290 units long.

Step-by-step explanation:

This is a 3D version of the pythagorean theorem.

2D c = sqrt(a^2+b^2) or c^2 = b^2 + a^2

3D bar length = sqrt(FG^2 + BC^2 + FC^2)

so: sqrt(16^2 + 288 + 30^2) = 290

Have a good day.

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.
