Please Help Please provide explanation as well! A triangle has vertices on a coordinate grid at J(5,10), K(5,-9), and L(-5,-9). What is the length, in units, of {JK} ?

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.

what i would say the best answer is a. 40.5
