<span>One kilometer is equal to 0.621371 miles. Conversely, one mile is equal to 1.609344 kilometers. One liter is equal to 0.264172 gallons, and one gallon is equal to 3.78541103373138 liters. Thus, 12.4 kilometers per liter is equal to 29.16661 miles per gallon as 1 km/l = 2.352145833 mpg.</span>
The range is how much it spans in f(x), f(x) is a line, it has no max/min, so it's enough to substitute the least and greatest values of your domain:
f(-2) = -5, f(4)=7,
Range = [-5,7]
By solving a system of equations, we will see that m measures 12 units.

How to get the measure of m?</h3>
Notice that we have 3 right triangles.
Then we can write the equations:
cos(a) = 6/m
For the small triangle on the left, where m is the hypotenuse.
cos(a) = m/(6 + 18)
For the larger triangle (the one composed of the two triangles).
Where in both equations, angle "a" is the one in the top left.
Then we have the system of equations:
cos(a) = 6/m
cos(a) = m/(6 + 18)
Then we can write:
6/m = m/(6 + 18)
If we simplify the expression, we get:
6*(6 + 18) = m^2
6*(24) = m^2
144 = m^2
√144 = m = 12
Then we conclude that m measures 12 units.

Answer:
a. The difference in rainfall is 4.03in
b. The total amount of rainfall for the year is negative, -1.73
Step-by-step explanation:
a. Wettest month 2.36in and dryest month -1.67in
2.36
-1.67
-------
4.03
b. -0.45 + -0.88 + 0.94 + -1.67 + -0.96 + 0.83 + 2.36 + 1.39 + 0.35 + -1.35 + -0.9 + -1.39 = -1.73
