Comment: This is not an easy exercise, but don’t let the surface mess of the picture put you off. The purpose of the exercise is to challenge you to think hard about very important issues in a new way and at the same time to challenge you to become more skillful at connecting graphs with ideas. We hope you won’t give up and that you’ll feel that what you learn from the time you spend is worth it. Give it a shot, see how far you can get, and if you get stuck, skip to the five exercises that come after the graphs, do those, and then come back to this one.

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

50- 250 is correct i did that one too

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.
