Answer:
The pre-image Q is [tex]Q(x,y) =(8,4)[/tex] .
Explanation:
From Linear Algebra, we can define dilation by the following expression:
[tex]Q'(x,y) = O(x,y) + k\cdot [Q(x,y)-O(x,y)][/tex] (1)
Where:
[tex]O(x,y)[/tex] - Reference point, dimensionless.
[tex]Q(x,y)[/tex] - Original point, dimensionless.
[tex]Q'(x,y)[/tex] - Dilated point, dimensionless.
[tex]k[/tex] - Dilation factor, dimensionless.
If we know that [tex]O(x,y) = (0,0)[/tex], [tex]Q'(x,y) = (16,8)[/tex] and [tex]k = 2[/tex], then the original point is:
[tex]Q'(x,y)-O(x,y) = k\cdot [Q(x,y)-O(x,y)][/tex]
[tex]Q(x,y) = O(x,y) +\frac{1}{k}\cdot [Q'(x,y)-O(x,y)][/tex]
[tex]Q(x,y) =(0,0)+\frac{1}{2}\cdot [(16,8)-(0,0)][/tex]
[tex]Q(x,y) =(8,4)[/tex]
The pre-image Q is [tex]Q(x,y) =(8,4)[/tex] .

In 2014, Russia occupied and subsequently annexed this portion of the
Ukraine with relatively no resistance?*l
A. Italian Peninsula
B. Armenian Peninsula
C. Crimean Peninsula
D. Balkan Peninsula
Answer:
the answer is Crimean peninsula
Answer:
Crimean Peninsula in Ukraine
Explanation:
Russian Expansion and Political Interference
After the Cold War ended, the United States and its European allies began to view Russia as less of a security concern. Instead, they looked for ways to cooperate politically and economically with the former adversary. This period of relative peace was broken in 2014 when Russian military forces moved into and occupied several eastern Ukrainian provinces and the region of Crimea. Russia has taken on a more aggressive role in the world, largely under the leadership of Vladimir Putin.
Putin, a former KGB foreign intelligence officer, rose to power and became prime minister and president of Russia. Putin has used his power to increase Russia's economy and has sought to regain the former glory and power of the Soviet Union. The standard of living has risen under his regime, and he is thought to be widely popular. However, there's also a question as to how reliable Russian elections and favorability ratings are. Free speech continues to be limited in Russia, and protests are discouraged through increased fines and even prison time. Corruption has become more widespread, as well. Russia spends proportionately more on its military than the United States. Cyber-warfare and espionage form one of the nation's most effective means of attack. The FBI has confirmed that Russia was responsible for intervening in the US 2016 election. In 2020, President Putin ordered amendments to the Russian constitution that would allow him to remain in power past term limits until 2036, signaling that Putin's Russia will continue to be a force to resolve.

C. people who are believed to be the first people to settle in an area
Explanation:
This means that they came from a place, to a new place, and settled the land. The Pilgrims are an example of colonists.
~theLocoCoco
This layer of the Earth is hot,solid and made of iron what is it
Just as climate has affected the settlement and agricultural activities of humans, likewise, humans have extensively modified the physical environment. Such modifications have been facilitated by globalization and urbanization. Human action such as the operation of industrial plants and power generating facilities has increased acid precipitation. Acid rain has the potential to damage forests, kill fish, and damage lakes. Excessive use of water is depleting ground water systems and creating water resource shortages.
1. Reset the map.
2. Select Water Resources Vulnerability. Select Acid Rain (U.S) and Split map window.
Compare the two maps and determine which statement is true.
A. Both acid rain and water resource vulnerability are extremely high for the Midwest.
B. Whereas the Southwest generally has extremely high water resource vulnerability, acid rain is a major issue on the East Coast.
C. Both acid rain and water resource vulnerability are extremely high for much of the East Coast.
D. Both acid rain and water resource vulnerability remain an issue for much of the Southwest
E. Whereas the East Coast generally has extremely high water resource vulnerability, acid rain is a major issue in the Southwest.
The statement which is true is that, "Whereas the Southwest region in U.S. generally has extremely high water resource vulnerability, acid rain is a major issue on the East Coast."
What do you mean by water resource vulnerability?The water resource vulnerability is defined as the tendency of water resource systems to break down because of the external influences. Vulnerability of water resources includes two aspects- sensitivity and adaptability of water resource systems to external driving factors.
The water resource vulnerability includes vulnerability of water quality and quantity. Thus, because of the climate change and human activities, human society is facing water resources shortage, frequent natural calamities, and a series of problems which leads to the increase in the vulnerability of water resource systems.
What is acid rain?Acid rain is a form of precipitation which is unusually acidic, with acidic components such as sulfuric or nitric acid which falls to the ground from the atmosphere in wet or dry forms. This includes- rain, hail, snow, fog, or even dust that is acidic.
Which part of the U.S. is most affected by water resource vulnerability?
The part of the United States which is most affected by water resource vulnerability is the Southwestern region of United States. This region stemmed mainly from consumptive uses whereas the vulnerability in watersheds of the southern US was due to changes in flooding, water quality issues, and other uses.
Which part of the U.S. is most affected by acid rain?The region of the United States which is most affected and harmed by acid rain is the East Coast, including the Appalachian Mountains and the Northeast Some.
Thus, acid rain occurs naturally, but when sulfur dioxide and nitrogen oxide emissions from smokestacks combine with rain they tend to make sulfuric and nitric acid in amounts which harm the environment.
Hence, option B is correct.

Which of the following events was NOT a cause of the Russian Revolution?
A. poor working conditions in cities
B. Czar Alexander II's limited reforming
C. government policy known as "Russification"
D. adoption of Marxism
Answer:
B but don't be surprised if it is D.
Explanation:
Russification was a thorn in the side of the rulers. People do not like giving up their culture. It was a cause.
The cities were poor -- especially after the disaster they suffered in WWI. The nobility was not liked. That was a cause.
Czar Alexander may have been slow to reform, but he was not the main culprit. I think this is an answer you should consider carefully. (B)
I would use the adoption of Marxism. That was not made official until After Lenin came to power. The vocabulary was often used by the leaders, but most of the peasants didn't know it's meaning.
The answer is between B and D. I would pick D, but I think you are intended to answer B.

The types of currents shown here are called ______ currents
Answer:
Looks like Tectonic
Explanation:
Hope this helps
The types of currents shown here are called the Convection currents.
What are the Convection currents?The convection is a process of heat transfer by the movement of fluids (gas or liquid) between regions of various temperatures. If convection occurs naturally it is called natural convection or free convection. If convection is forced to occur, say, if fluid is circulated using a pump r a fan, it is called forced convection.
Convection currents are generated by the differences in densities of the fluid that occur due to the temperature gradients. The activity that results from the continuous replacement of the heated fluid in the area of the heat source by the nearby present cooler fluid is called a natural convection current.
The convection current cannot take place in solids.

Answer:
If you are talking about settlers who went to America...
The first settlers came to escape religious persecution (the pilgrims), and eventually they also got tired of British rule so they wanted to separate from Britain. Later settlers came because they wanted to seek freedom in the new world that they didn't receive in their own old homeland.

Hope it will help you.......Not all areas on Earth's surface receive the same amount of radiation because Earth's surface a. is flat has continents on it b. is curved d. is mostly water Please select the best answer from the choices provided C С D
Answer:
Earth's surface receives different amounts of solar radiation because it is curved.
Explanation:
Earth, like all planets, is curved, or rather it has a round shape. More specifically, Earth has a generalized elliptic shape, though if we go into detail then it is a geoide. Such a shape means that not all parts of the planet can get the same amounts of solar radiation because of the different angles at which the sunlight falls on the surface.
The areas that are located around the equator are the ones that receive solar radiation at direct or close to direct angle throughout all of the year. This is results in a large concentration of the rays and the surface hits up. On the other hand, around the poles, the solar radiation that is received comes at very low angles. This results in a wide dispersal of the rays so the surface doesn't heat up enough and that is why the temperatures are always low.
North Pole
1. Canada is located at a much higher latitude than Mexico. How does climate or
temperature change as latitude increases?
Answer:
Thanks for the question,
Due to the latitude and and distance from the equator the temperatures drop the further in a region,i.e. the equator because of the curvature of the world. In areas nearer to the poles, daylight has a larger space of atmosphere to experience and also the sun is at a lower angle within the sky.
In case of Canada and Mexico, Mexico lies near the equator and the sunlight directly hits the surface and therefore the climate and temperature in Mexico is constant and tropical. But, when we comes to Canada the latitudes increases and the temperature decreases due to the inconstant amount of sunlight. (Please check the attached Maps below which explains the latitude-temperature and latitude-climate effects)
Hope it helps!<3
Answer:
IS WITH EXPLANITION
Explanation:
latitude affects climate due to the rays of the sun as Mexico is slightly in the Torrid zone and Canada is in the North temperate zone so it is colder than Mexico thus proving latitude increase can effect climate
