The use of machinery made work easier and more efficient, therefore more raw materials were needed because final products could be produced much faster.
Vegetation can be assumed to reduce overgrazing of grasslands if it is woody vegetation. Woody vegetation would act as a physical barrier to grazers. The roots of vegetation, including grassland, bind soil together, thereby preventing erosion.
Deforestation occurs in Haiti because of a lack of energy options in the country. Haitians cut down trees for burning or charcoal production.
Answer: Metal Detectors
Explanation: Metal detectors are inexpensive and easy to use equipment used to discover relics of the past. While it is useful in archaeology as a tool that discovers objects from the past quite easily, it is also a threat to archaeology. Some hobbyists and looters who come across archaeological finds which may be important to understanding past civilizations or a different era do not report these finds. Even worse, some looters knowingly infringe on archaeological sites and are aided by the metal detectors.
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.
