PLEASE HELP! triangle KL in which angle K is a right angle and angle L measures b degrees A. sin(b°) = three fifths B. sin(b°) = four fifths C. sin(b°) = five thirds D. sin(b°) = five fourths

the answer is 489

step-by-step explanation:

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.
