I believe that what you need is to match the word with the definition. Here it is!:
emigration
leaving one's homeland to settle in a new place
immigration
movement
of people to a new country
migration
the movement from one place to another
underpopulation
birth rate insufficient to replace the existing population
urbanization
development the increase in the population of a city
sustainable
development the ability to meet current needs without
reducing the ability to meet future needs
unsustainable development
resources being used up at a faster rate than they can be replenished
overpopulation
the number of people exceeds the available natural resources in an area
The physical environment has played a very big role in the settlement patters in Ukraine, as well the economic activities of the people that lived in this area.
The settlement patterns in Ukraine are relatively simple, as most of the settlements have been made on the banks of the large rivers, such as the Dnipro and Dniester, and Don, as well as on the coastlines of the Black Sea and the Sea of Azov. So we can say that the settlements have been built in close proximity to the larger water bodies.
The location of the settlements around the water bodies was not a coincidence, as these water bodies were used for trade, so the people living in Ukraine were heavily engaged in the trade that was going through their territory. Also, Ukraine is part of the Eurasian steppe, so people were trading a lot on land as well, especially because they were a transition zone between Asia and Europe.
Answer:
64
Explanation:
The question is incomplete without the expression that would be used to find the constant necessary to make a perfect square trinomial.
I would show you how to find the constant necessary to make a perfect square trinomial using the expression below:
x² - 16x + c
The expression above is in the form of a quadratic: ax² + bx + c
Where a = 1, b = -16, c = constant
First thing we do, is to square half the coefficient of x
Coefficient x above = b = -16
square of half the coefficient of x = (-16/2)²
Expand it, we have = -16/2 × -16/2 = 8×8 = 64
Replace the constant with 64
x² - 16x + 64
b/2 = -16/2 = -8
(x - 8)² will give a perfect square trinomial
Therefore the constant which makes the above expression a perfect square trinomial is 64
The faintest star a person can see through a 10 metre telescope is 10 times fainter than a 1 metre telescope.
All the other things or characteristics are equal, given the fact that it is a refracting telescope, like the fact that
- it shows details 10 times bigger.
- the 10 metre telescope looks 10 times brighter.
The PW1000 is one such telescope that can be given as an example of a 10 metre telescope.
