  A)  5×10^-7

Step-by-step explanation:

When you factor out the powers of 10, you have ...

__

There are a couple of things to notice here. One is that addition can only be carried out if the values have multipliers with the same power of 10. If they don't, one or the other needs to be adjusted so they do. In this problem, no adjustment is necessary.

Another thing to notice here is that the rules of exponents apply.

  (a^b)(a^c) = a^(b+c)

  (a^b)/(a^c) = a^(b-c)

If you set your (scientific or graphing) calculator to display numbers in scientific notation, you can perform this arithmetic on your calculator to see the simplified result. Of course, a spreadsheet can do this math and give you a scientific notation display, too.

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.

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
