1. According to the plots, the curves intersect when 
and 
.
We can confirm this algebraically.
(where 
is an integer)
We get the two solutions we found in the interval [0°, 360°] with 
in the first case, and 
in the second case.
2. We have 
when 
. For the given plot domain [0°, 360°], this happens when 
.
3. The domain for both equations is all real numbers in general, but considering the given plot, you could argue the domains would be [0°, 360°].
is bounded between -1 and 1, so 
is bounded between -1 + 2 = 1 and 1 + 2 = 3, and its range is [1, 3].
Likewise, 
is bounded between -1 and 1, so that 
is bounded between -1 + 3 = 2 and 1 + 3 = 4, so its range would be [2, 4].
Divide your numerator by the denominator to find the decimal. 11÷1000=.011 ANSWER: .011
Simple,
4x9x2.2 = volume = 79.2 cubic centimeters
79.2/1000 = 0.0792 litres
not sure if you wanted it in cubic or litres FYI if it doesn't say put the answer in cubic :)
