What is the intersection of AD and CD? Explain.

point D

Step-by-step explanation:

AD is a line and CD is a line

The intersection of two lines is a point  ( if the lines intersect)

The two lines intersect at point D

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.

the answer is y = 11.54

hope this : )
