Answer:
The answer is below
Explanation:
The question is not complete, the coordinates of K and M are not given. Let us assume The coordinates are at K(1, -6) and M(9,-2)
Answer: If a line segment AB with coordinates at 
is divided by a point O(x, y) in the ratio n:m, the coordinates of point O is given by the formula:
K(1, -6) and M(9,-2) are divided in ratio 1:3 by point L. Let us assume L is at (x,y), hence the coordinate of point L is given as:
Point L is at (3, -5)
Answer:
The investigation of past atmospheric compositions and past climate will help us understand the extent to which the use of fossil fuel has, and is still altering the atmosphere. These investigations will shed light on how much damage or good (if any) these fossil fuel usage is doing to the atmosphere and then we may from these investigations, put regulations, or total ban on some of these fossil fuels (if not ban their usage completely) in an effort to return the atmosphere back to its healthy composition, and proportion of useful elements.
Advantage: Because of your accent, some people may be interested in you. Not in you particularly, but since your accent sounds nice, they may be interested from where you are and the history of that place.
Disadvantage: Some people may find your accent weird and stuff, you may get bullied and made fun of because of it.
