identify one difference between two Democratic revolutions that occurred between 1750 and 1830 and then explain specifically what caused the difference to occur in a society
The correct answer to this open question is the following.
I am going to pick the two most important revolutions in that period. First of all, the American Revolutionary War and then the French Revolution.
To me, one difference between the two revolutions movements is the following. On one hand, the American Revolution was a rebellion to get independence from another country, in this case, Great Britain, a nation that had its own political and economic interests in the North American colonies. On the other hand, the French Revolution was an armed revolution from the poorest social classes in France that lived unders¿ hash economic conditions and started the rebellion against the King of France.
Enter a function that models the given situation. Select the correct domain from the situation. Use set notation for the domain. A bicyclist travels at a constant speed of 18 miles per hour for a total of 27 minutes.
Answer:
Explanation:
A bicyclist travels at a constant speed of 18 miles per hour for a total of 27 minutes
Using x to represent domain and
y to represent distance traveled
Domain (x) is number of hours used
Range (y) is distance traveled
speed = 18 miles per hour
time = 27minutes = 0.45hours
Since 60 mins makes 1hour
Therefore, 27mins will make x hour
X hour =27mins/60mins
X hour=0.45hours for 27mins
Distance = speed × time
Distance = 18 ×0.45= 8.1miles
Number of hours( x) used is from 0 to 0.45 hours
So domain which is the number of hours uses is 0 to 0.45hours
Range which is distance travelled is 0 to 8.1 miles
