North Pole:
Essentially a sea, an "ocean" located in the northernmost region of the Earth. It is surrounded by a layer of permafrost. This is also the main feature that makes the big difference between this area and Antarctica.
Has a maximum depth of about 4,000m.
Antarctic:
Is a continent. Due to its continental nature, the climate here is much harsher than that of the Arctic.
Also because it is a continent, a "giant iceberg" about 3,000m above average sea level, so the temperature is lower than Antarctica (the higher you go, the colder it gets).
Covering an area of about 14,000,000 square kilometers, twice the size of Australia.

Find the coordinates of a point on the directed segment from (3,-2) to (8,0) that divides it into a ratio of 3:1.
Answer:
[tex](x,y) = (\frac{27}{4}, -\frac{1}{2})[/tex]
Explanation:
Given
[tex](x_1,y_1) = (3,-2)[/tex]
[tex](x_2,y_2) = (8,0)[/tex]
[tex]m : n = 3 :1[/tex]
Required
The coordinates of the point
This is calculated using:
[tex](x,y) = \frac{1}{m+n}(mx_2 + nx_1, my_2 + ny_1)[/tex]
So, we have:
[tex](x,y) = \frac{1}{3+1}(3*8 + 1*3, 3*0 - 1*2)[/tex]
[tex](x,y) = \frac{1}{4}(27, -2)[/tex]
So, we have:
[tex](x,y) = (\frac{27}{4}, -\frac{1}{2})[/tex]
