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.
Answer:
Developing countries are more vulnerable to natural disasters because people live in areas at high risk from natural disasters (e.g., unsafe urban areas), the housing is poorly built and can be easily damaged in the event of a disaster, countries are not equipped with early warning systems, and they have few assets and ...

Determine an equation of a perpendicular line but with the same y intercept

Open bracket

A linear equation is represented with:

Where


By comparison:


So, the slope of
is m
Because the new line is perpendicular to
, the relationship between their slopes is:

Where
slope of the first equation
slope of the second equation
Substitute m for
in 

Hence, the slope of the new equation is: 
From the question, we understand that they have the same y intercept.
So, the equation of the new equation is:

The answer to the question is true
