Explanation:
Urban cities emerged in Europe during the second industrial revolution when there was many new things introduced both good and bad urban areas would be very crowded as many people would move into urban cities due to the mass production of new technology an apartment of one room would consist of at least two families including grandparents. During this time many people would get sick because of how polluted cities would be which also suggests that people would move from rural areas to urban areas and Vice versa
Answer
Americans believed that the West was divinely enjoined to be part of the United States.
<u>Explanation:</u>
Migration was an important factor in the development of America. The West attracted many peoples. Future generations looked at the borders of their settlements in the western crisis zones. A huge amount of land sold very cheaply or given away free of charge made it easier to set up a farm without worrying about initial debt.
So the unsuccessful and unemployed citizens takes this to escape from bad times and headed west, where there was cheap land, and even set up homesteads. Gold and other precious metals were discovered and that led some people there to gain wealth without hard work. The reservation system has been designed so that Native Americans stay away from land that European Americans would like to settle.
The eastern settlement was replaced by the Great Plain and the loss of the bison and growth affected in the number of white settlements. The arrival of Europeans on the continent affected the Midwest. But before that the American Indians were already started to occupy those western lands.

find the area under the curve first
![\int\limits^{\sqrt[3]{\pi}}_0 {x sin(x^3)} \, dx =0.61157809233184](https://tex.z-dn.net/?f=%20%5Cint%5Climits%5E%7B%5Csqrt%5B3%5D%7B%5Cpi%7D%7D_0%20%7Bx%20sin%28x%5E3%29%7D%20%5C%2C%20dx%20%3D0.61157809233184)
then solve c∛π=0.61157809233184
c≈0.41757577488026
round if necicary

alright, solve where they itnersect
x²=y=mx
x²=mx
x²-mx=0
x(x-m)=0
set to zero
x=0
x-m=0
x=m
they intersect at x=0 and x=m
which one is on top?
hmm
y=mx will always be on top (I don't know how to prove that but it's on top)
so we do
solve
![\int\limits^m_0 {mx-x^2} \, dx =[\frac{mx^2}{2}-\frac{x^3}{3}]^m_0](https://tex.z-dn.net/?f=%20%5Cint%5Climits%5Em_0%20%7Bmx-x%5E2%7D%20%5C%2C%20dx%20%3D%5B%5Cfrac%7Bmx%5E2%7D%7B2%7D-%5Cfrac%7Bx%5E3%7D%7B3%7D%5D%5Em_0)
so
m³=48
m=2∛6
2nd one, please correct me if i’m wrong .
