Find the total area (in terms of k) of the prism. place "k" last in your formula. t. a. =

Area of base = 2 (0.5 x 20" x k) = 20k

The sides of the prism are rectangles, with width 6" and length (20"/5) = 4".

Area of sides of prism = 5 (6" x 4") = 120

Total Area T.A. = (120 + 20k)

This is correct because I did this question and got it right.

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.
