The circle has two forms of equation - General Form and Standard Form. The general form of the equation of the circle would be x^2 + y^2 + Dx + Ey + F = 0. The constants of this equation are D , E and F. The way to use general form is to complete the square and then proceed the equation in standard form. In that way we can identify the radius and center of the given circle.
The three different types of Western European agriculture are:
- Mediterranean polyculture; it is practiced alongside the Mediterranean, in here we have farming of wheat that grows in the mild winters and is cropped in spring, as well as plantages with deep rooted trees that are resilient to droughts like the vine trees and olives.
- Dairy farming; this type is typical for the places that are colder and cloudy like the Alps, the Baltic, the British Isles and Brettony. This is places are focused on dairy farming because the conditions don't allow anything else to be farmed, but it is excellent for dairy farming.
- Mixed livestock and crop farming; this agricultural belt is found between the Mediterranean polyculture region and the dairy farming region. In here there's not really focus on specific thing to farm but instead there's multiple plants and animals being farmed.
D. To keep different races and ethnicities separated in order to avoid conflict.
