A free-trade zone is by definition “a place where trade is left to happen without tariffs(tax on imports/exports), quotas, or other restrictions”. An example of a free-trade zone is the European Union. There are no tariffs, quotas, or other restrictions placed on trading within the EU countries (they even share a currency). This allows for them to place products at a cheaper price for good quality and still get enough money to grow wealth within the different countries.
Answer:
Explanation:
Alright so the way to do this is to use properties of integrals to make our life easier.
So we have:

So lets break this up into two different integrals that represent the same area.

Lets think about what is going on up there. The integral from four to zero gives us the area under the curve of f(x) from four to zero. If we subtract this from the integral from one to zero (the area under f from one to zero) we are left with the area under f from four to one! Hence:

But since we have these values we can say that:
-3 - 2 = -5
Which means that
= -5
So now we can evaluate 
Lets first break up our integrand into two integrals
= 
Now we can evaluate this:
We know that
= -5
So:
where x is evaluated at 4 to 1 so
-15 + 2(3)
So we are left with -15 + 6 = -9
I think it might be A.) Day. Because when the axis is pointed towards the sun, that shows it is day because that area has sunlight in which you get during the day. It is night when the axis is pointed away from the sun because there is no sunlight in that area which causes darkness in which we get during the night obviously. Winter occurs when the earth is far away from the sun, in which there is no heat, and closest to the sun in which we do get heat, there will be Summer.
Hope this helps some.
