Give an example of a 2x2 matrix whose determinant is 13.

how would i come up with numbers? is it just a random guess and check?

the equivalent expression are always the hardest ones but you look at the gcf also

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.
