Calculate the area of each shape below. Figures are not drawn to scale.

The area of the traiangle=Area of both traingle

=1/2×4.4×6.1 +1/2×4.4×3.3

=2.2×6.1+2.2×3.3

=2.2(6.1+3.3)

=2.2×9.4

=20.68in^2

the infinity sign

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.
