Answer:
The coordinates of the missing point if W is the midpoint of XY is [tex]Y(x,y) =(1,0)[/tex].
Explanation:
From Linear Algebra we define the location of midpoint by the following expression:
[tex]W(x,y) = \frac{1}{2}\cdot X(x,y)+\frac{1}{2}\cdot Y(x,y)[/tex] (1)
Where:
[tex]X(x,y)[/tex], [tex]Y(x,y)[/tex] - Endpoints of the line segment, dimensionless.
[tex]W(x,y)[/tex] - Midpoint, dimensionless.
If we know that [tex]W(x,y) =(4,-2)[/tex] and [tex]X(x,y) = (7,-4)[/tex], then the location of the point Y is:
[tex]Y(x,y) = 2\cdot W(x,y) -X(x,y)[/tex]
[tex]Y(x,y) = 2\cdot (4,-2)-(7,-4)[/tex]
[tex]Y(x,y) = (8,-4)-(7,-4)[/tex]
[tex]Y(x,y) =(8-7,-4+4)[/tex]
[tex]Y(x,y) =(1,0)[/tex]
The coordinates of the missing point if W is the midpoint of XY is [tex]Y(x,y) =(1,0)[/tex].

Explanation:
Is the desert sand closer in composition and in the degree of rounding and sorting as the river sand or the beach sand and why
Answer:
The three sand are similar in composition, since all are formed 90% by quartz. They are also similar in roundness, as they all have large particles that allow a very sandy soil with low water retention.
Explanation:
The desert area of the river and the beach have a very similar composition, since 90% of these sands are composed of quartz. however, the similarity does not mean that these sands are the same, as they are not, since the sands of the beach and the river may have a little more material, such as animal remains, making these sands also have carbon in composition, something that desert sand has in less quantity.
In addition, both sands have large particles that promote strong aeration in the soil, but a very rapid loss of organic matter.
In general, what can you conclude about the lengths AC of BD and if the lengths of AB and CD are equal?
Answer:
When the lengths of AC and BD are equal, the lengths of AB and CD are also equal.
Explanation:
Got this wrong for yall but its the exact right answer.
Answer:
When the lengths of AB and CD are equal, the lengths of AC and BD are also equal.
Explanation:
In rhombus ABCD, the diagonals AC and BD intersect at E. If AE = 5 and BE = 12, what is the length of AB?
Answer:
The length of AB is 13 units
Explanation:
consider the sketch of the rhombus below. A rhombus is a plane shape that has all its sides equal, but unlike a square, it is skewed at an angle.
We can notice that the right angle triangle is formed between points AEB. This is a very good indicator showing that we can apply Pythagora's theorem to solve our geometry problem here.
We are looking for the length of AB. This is the hypotenuse side of the triangle. From Pythagoras' theorem,
[tex]AB=\sqrt{(AE)^2 +(BE)^2}[/tex]
[tex]AB=\sqrt{5^2 +12^2} =13 units[/tex]
The length of AB in rhombus ABCD is 13 units.
Pythagoras theorem is used to show the relationship between the sides of a right angled triangle.
Applying Pythagoras theorem in triangle ABE:
AB² = AE² + BE²
AB² = 5² + 12²
AB² = 169
AB = 13 units
The length of AB in rhombus ABCD is 13 units.

Fill in the blanks to complete each statement about continental drift. Continental drift was first proposed by a scientist named Alfred______ . He theorized that the_____ were once one large landmass that drifted apart very slowly over a long time.
Answer:
Continental drift was first proposed by a scientist named Alfred Wegener. He theorized that the continents were once one large landmass that drifted apart very slowly over a long time.
Explanation:
Alfred Wegener was the scientist that came up with the idea that Earth's continents are not static but that they move slowly. While he came up to a lot of resistance and ridicule when he first proposed this, he did not give up, instead, he continued in his mission to prove his theory and managed to find numerous pieces of evidence to support it.
Some of the evidence that Wegener found were the mathcing continental margins, matching mountain chains in different continents, fossils, mid-ocean ridges, etc. When he managed to come out with all of the evidence the scientists that previously thought that he is crazy were shocked and saw that they were the ones that were wrong all the time. Quickly, this theory was accepted, and more and more evidence was obtained to support it, so the world finally knew that the continents are moving slowly, and that they were one big landmass in the distant past and that there are high chances that something like that will happen in the future as well.
Answer: Wegener and continents

Find the distance between the pairs of points E(5,-1), F(-4,11)
Answer:
15
Explanation:
Step one
Given data
The point coordinate is E(5,-1), F(-4,11)
Hence
x1=5
y1=-1
x2=-4
y2= 11
Step two
Required
Distance between the two coordinate point
Applying the Pythagoras theorem for the distance between two points
d=√((x2-x1)²+(y2-y1)²)
d=√((-4-5)²+(11-(-1))²)
d=√-9²+12²
d=√81+144
d=√225
d=15
Hence the Distance the points is 15

Iceland is sitting on top of two plates: the continental portion of the North American plate and the continental portion of the Eurasian plate. These plates are diverging. Which landform would you expect to form?
a rift valley
a non-volcanic mountain chain
a volcanic island arc
a mid-ocean ridge
a volcanic mountain arc
Answer:
a mid-ocean ridge
Explanation:
The landform expected to be formed along this margin is a typical mid-ocean ridge.
A mid - oceanic ridge forms along the margins of a divergent zone. In this place, mafic and ultramafic magma are brought to the surfaceThey cool and solidify in such environment. Iceland harnesses the geothermal energy from this diverging boundary to meet some of her energy needs.Given equation 8x - 10=6x

Latitude ranges from 0 degress * at the equator to 90 degrees * N or 90 degrees * S at a latitude of at the north and south poles. What type of ecosystem would you be most likely to find at a latitude of 5 degrees * N ?
Answer:
The tropical rainforest is the ecosystem most likely to be found at a latitude of 5 degrees North.
Explanation:
There are numerous different biomes in the world and they are primary distributed in accordance with latitude, though the high mountains act like isolated islands where there are biomes that are not expected for the given latitude. The lower latitudes are known as tropics, and here we can find the tropical climate types. If we are even more specific, at the lowest latitudes, around the Equator, then we will find tropical rainforests.
At 5 degrees North, the ecosystem that will be found will be the tropical rainforest. This ecosystem will be found here because of the proximity to the Equator. The climate is warm and wet, mostly monotonous throughout the year, and the constant heat and rainfall have provided good conditions for the growth of thousands of different types of plants, creating an area of lush vegetation. With the very high amount of vegetation present, there is a very high amount of food sources, thus there is an abundance of animals as well, much more than at any other terrestrial ecosystem.

Select 5 countries where people aged between 24- 40 mostly want to migrate.
Answer:
North Macedonia, Albania, Serbia, Romania, and Bulgaria.
Explanation:
There are a lot of countries in the world where people in the age group of 24 to 40 would mostly want to migrate to other countries. A region that is in this kind of situation is the Balkan, and while in most of the countries this is the case, the situation is most dramatic in North Macedonia, Albania, Serbia, Romania, and especially Bulgaria.
It is not a small difference when it comes to people wanting to remain and people wanting to move, but it is in the range of 70,80, and even 90% of the people of this age group that say that they would prefer to migrate in another country. There are a lot of reasons for this, and some of them are politics, corruption on every level of the society, in order to get a job you usually need to be a member of the leading political party or to have a very good connection while your skills and qualities are often not taken in consideration, the economies are not at a good level, the living standard is low for European standards, and the pollution is among the highest int he world. All of this has led to the rapid loss of population of this age group in these countries, which in turn has led to a rapidly aging population and much lower birthrates. Bulgaria has it the worst and it is the country that has lost the biggest percentage of the population through migration in the last few decades.
