Point R is located at (1, 2) on a coordinate grid. Point S is located at (4, 5) on the same coordinate grid. What is the distance from point R to point S, rounded to the nearest tenth?
A. 3.2 units
B. 4.6 units
C. 7.6 units
D.
10.0 units

The answer is option... D

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is 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.
