What is the length of segment AB?

10
12
13
15

Side AB is 13 plots long.

Step-by-step explanation:

Square sides A and side B

12 x 12 = 144

5 x 5 = 25

Now add the sides together. Then, find the square root of the sum.

144 + 25 = 169

= 13

Check your work:

13 x 13 = 169

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.
