Answer:
b
Explanation:
Complete the sentence about the crystallization of magma.
The rate at which magma
———— determines the
of the ———— crystals in the new rock.
Answer:
Cools
Size
Explanation:
The rate at which magma cools determines the size of the crystals in the new rock.
When magma cools rapidly, nucleation centers are much and they do not aggregate to form larger crystals. This will give a rock that is finely grained.
When magma cools slowly, the nucleation centers grows and much time is afforded for big crystals to form within the mass.
Most intrusive igneous rocks usually have big crystals because the crystals have enough time to aggregate around nucleation centers. Extrusive igneous rocks cools rapidly and their crystals are very fine grained due to the condition prevalent on the surface.Answer: cools and size is correct

which point is the image of point B(-2,4) reflected over the x axis?
Answer:
(-2,-4)
Explanation:
The point (-2,4) is in the 2nd quadrant so when flipped over the x-axis it is then in the 3rd quadrant which means the x and y coordinates are negative. Thus, our answer is (-2,-4).

Explanation:
Is (x - 1) a factor of (x4 - 2x3 + x2 - x + 1)?
Factor?
Why? [Select]
Answer:
here's the proof
Explanation:
x-1=0
x=1
so
f(x)=x⁴-2x³+x²-x+1
f(1)=1⁴-2.1³+1²-1+1
f(1)1-2+1-1+1
f(1)=2-2
f(1)=0
as we know When f(c)=0 then x−c is a factor of f(x)
hence x-1 is a factor of x⁴-2x³+x²-x+1

What is the value of X6?
Show the solution.
Answer : The value of [tex]x_6[/tex] is [tex]\sqrt{7}[/tex].
Explanation :
As we are given 6 right angled triangle in the given figure.
First we have to calculate the value of [tex]x_1[/tex].
Using Pythagoras theorem in triangle 1 :
[tex](Hypotenuse)^2=(Perpendicular)^2+(Base)^2[/tex]
[tex](x_1)^2=(1)^2+(1)^2[/tex]
[tex]x_1=\sqrt{(1)^2+(1)^2}[/tex]
[tex]x_1=\sqrt{2}[/tex]
Now we have to calculate the value of [tex]x_2[/tex].
Using Pythagoras theorem in triangle 2 :
[tex](Hypotenuse)^2=(Perpendicular)^2+(Base)^2[/tex]
[tex](x_2)^2=(1)^2+(X_1)^2[/tex]
[tex](x_2)^2=(1)^2+(\sqrt{2})^2[/tex]
[tex]x_2=\sqrt{(1)^2+(\sqrt{2})^2}[/tex]
[tex]x_2=\sqrt{3}[/tex]
Now we have to calculate the value of [tex]x_3[/tex].
Using Pythagoras theorem in triangle 3 :
[tex](Hypotenuse)^2=(Perpendicular)^2+(Base)^2[/tex]
[tex](x_3)^2=(1)^2+(X_2)^2[/tex]
[tex](x_3)^2=(1)^2+(\sqrt{3})^2[/tex]
[tex]x_3=\sqrt{(1)^2+(\sqrt{3})^2}[/tex]
[tex]x_3=\sqrt{4}[/tex]
Now we have to calculate the value of [tex]x_4[/tex].
Using Pythagoras theorem in triangle 4 :
[tex](Hypotenuse)^2=(Perpendicular)^2+(Base)^2[/tex]
[tex](x_4)^2=(1)^2+(X_3)^2[/tex]
[tex](x_4)^2=(1)^2+(\sqrt{4})^2[/tex]
[tex]x_4=\sqrt{(1)^2+(\sqrt{4})^2}[/tex]
[tex]x_4=\sqrt{5}[/tex]
Now we have to calculate the value of [tex]x_5[/tex].
Using Pythagoras theorem in triangle 5 :
[tex](Hypotenuse)^2=(Perpendicular)^2+(Base)^2[/tex]
[tex](x_5)^2=(1)^2+(X_4)^2[/tex]
[tex](x_5)^2=(1)^2+(\sqrt{5})^2[/tex]
[tex]x_5=\sqrt{(1)^2+(\sqrt{5})^2}[/tex]
[tex]x_5=\sqrt{6}[/tex]
Now we have to calculate the value of [tex]x_6[/tex].
Using Pythagoras theorem in triangle 6 :
[tex](Hypotenuse)^2=(Perpendicular)^2+(Base)^2[/tex]
[tex](x_6)^2=(1)^2+(X_5)^2[/tex]
[tex](x_6)^2=(1)^2+(\sqrt{6})^2[/tex]
[tex]x_6=\sqrt{(1)^2+(\sqrt{6})^2}[/tex]
[tex]x_6=\sqrt{7}[/tex]
Therefore, the value of [tex]x_6[/tex] is [tex]\sqrt{7}[/tex].

Which of the following phrases best defines migration A forcing others to move away from their homes B encouraging others to move to a new place C spreading culture from one place to another D moving from one place to another to find a new place to live Please select the best answer from the choices provided ABCD
Answer:
D.
Explanation:
Migration isn't about being forced to move so A is wrong
It isn't about culture in any way so C can be eliminated
I don't know about encouraging others but D sounds much better because migration is about moving whether it is temporarily, permanently, or settling there so I think D sounds the best.

Explanation:
Air pressure is greatest ____ because there are more molecules of air pushing down from above. a. at the top of the mountain c. in the troposphere b. at sea level d. in the exosphere
Answer:
The answer is B, at sea level.
Explanation:
Air pressure is greatest at sea level because there are more molecules of air pushing down from above. Thus, option 'B' is the correct option.
Where the air pressure is the greatest?The lowest point in the atmosphere has the highest atmospheric pressure. Additionally, here is where the air is densest. As one ascends higher in the atmosphere, pressure and density drop. The mass of the atmosphere is drawn toward the surface of the earth by its gravitational field.
In actuality, 99.99997% of the atmosphere's bulk is contained within 100 kilometers of the earth's surface, whereas 90% of the atmosphere's mass is contained within 16 kilometers (Lutgens 17). The typical free route between air molecules is approximately 10 km at 600 km (Lutgens 18). From this point on, the atmosphere keeps getting thinner with height until it eventually combines with space itself.

What is Russia’s current relationship with neighboring countries that used to be part of the U.S.S.R?
Answer:
Well, it depends from country to country. With most of them they have good economical relations, which is normal, as the are mutually dependent on certain products. For example Russia is the main gas exporter in the wide region. In some countries, they even have larger political influence, such as Belarus, while for example with Ukraine they have bad political relations, due to crisis on Crimea.
Explanation:
After the collapse of Soviet Union strong economic ties between Russia and other countries that were part of it remained, but of course as the time passed things have changed. Recently, Russia re-emerged as a great force thus creating large political influence in certain countries. Therefore, they are seen as a threat by certain countries, especially by Ukraine.
