Explanation:
Where are the extra Green house gases coming from?
Most scientist think that human activities such as burning fossil fuels, using cars and other vehicles ,and clearing forest have increased the amount of carbon dioxide in the atmosphere. There are green house gases in our atmosphere,e.g. water vapor , carbon dioxide , methane nitro us dioxide and ozone.
They absorb heat from Sun rays and radiate in all directions, which warm's the Earth.The Earth could become too hot and this causes climate change which has a lot of effects on Earth. Earth's dry regions will become more drier and wet regions will become more wetter e.g.

Answer:
D. after 3 minutes, Sam is 40 meters from the dock.
Explanation:
For an input of 3, the function will produce a value of 40. That is in 3 minutes, the boat would have covered a distance of 40meters.
We can solve this problem using the given graph.
We know that this is a distance - time graph. The slope of this graph gives the value of the speed of the boat.
- From the time - axis, mark point 3 which corresponds to the input given.
- Trace it up to the point where it coincides with the graph.
- Then find the distance axis value of the point.
- Doing this yield 40m
So, in 3 minutes, Sam will row a distance of 40m.
