Find the slope of a line parallel to a line that contains the points (9, -3) and (-3, 8).

Answers

Answer:

[tex] Slope, \ m = \frac {11}{-12} [/tex]

Explanation:

Given the following points;

Points on the x-axis (x1, x2) = (9, -3)

Points on the y-axis (y1, y2) = (-3, 8)

To find the slope of a line parallel to a line;

Mathematically, the slope of a line is given by the formula;

[tex] Slope, \ m = \frac {Change \; in \; y-axis}{Change \; in \; x-axis} [/tex]

[tex] Slope, \ m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Substituting into the formula, we have;

[tex] Slope, \ m = \frac {8 - (-3)}{-3 - 9} [/tex]

[tex] Slope, \ m = \frac {8 + 3}{-3 - 9} [/tex]

[tex] Slope, \ m = \frac {11}{-12} [/tex]

Therefore, the slope of the parallel line is -11/12.

Knowing that rifts (red lines) generally open perpendicular to the rift (or sub-parallel to the light blue transform faults), which of the statements below about this area is incorrect?
a. the NW-trending Red Sea is a linear sea that is opening in a NE-SW direction
b. the ENE-trending Gulf of Aden is a linear sea that is opening in a NNE-SSW direction
c. the volcanoes in Africa define a narrow linear rift that is opening in a NW-SE direction
d. the volcanoes in Africa define a volcanic arc related to subduction off Africa's east coast

Answers

Answer:

d. the volcanoes in Africa define a volcanic arc related to subduction off Africa's east coast

Explanation:

Many crust plates move over the mantle. These plates are limited by three types of ridges or borders that differ in the movement they produce.

Boundaries types: Divergent, Convergent, and Transforming.

Divergent boundary: Occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. New crust is created by the molten materials rising from the mantle. The two plates at each side of the rift separate, and the stream of hot material creates a new seabed between them. It occurs an expansion of the sea bottom, which separates the plates. The divergence direction is transversal to the rift orientation.  Old plates get separated, and the new crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates.

a. the NW-trending Red Sea is a linear sea that is opening in a NE-SW direction.  CORRECT →  The diverging direction is perpendicular to the rift orientation.

b. the ENE-trending Gulf of Aden is a linear sea that is opening in a NNE-SSW direction. CORRECT

c. the volcanoes in Africa define a narrow linear rift that is opening in a NW-SE direction. CORRECT.  

d. the volcanoes in Africa define a volcanic arc related to subduction off Africa's east coast ⇒ INCORRECT. The collision between plates creates volcanic arches and continental arches. This process belongs to the convergent boundaries, in which two oceanic plates collide, or one oceanic plate crushes with a continental one.

The correlation between the number of hours Brad studies and the grades he gets is 0.8. Which phrase best describes the correlation between the number of hours Brad studies and the grades he achieves?

Answers

Answer: strong positive correlation

Explanation:

A positive correlation exists when the correlation coefficient that we've is greater than 0. This means that both variables that are given move in the same direction.

Since the correlation between the number of hours Brad studies and the grades he gets is 0.8, it means that there's a strong positive correlation due to the fact that the value is close to +1.

This means that the number of hours that Brad studied is a good predictor of

the grade that he gets in his examination but it's not perfect.

How would you be able to immediately tell whether a shale parent rock had been subjected to either intermediate-grade contact metamorphism or intermediate-grade mountain belt (regional) metamorphism?

Answers

Answer:

On the basis of heat and pressure the rock undergoes transformation.

Explanation:

The contact metamorphism occurs when magma comes into contact with the already existing body of rocks. Regional metamorphism occurs in wider areas of earths crust. It occurs in areas where the rocks have undergone deformation at time of orogenetic events. Metamorphic grades refers to the changes in the processing of rocks form low to high grade.  The shale rocks are metamorphized under intense heat and pressure to form slate thereby increase in the grade quality. If the rocks are subjected to contact metamorphism then slate is formed and if its regional metamorphism then phyllite, then schist, and finally, gneiss are formed.

Why do political discussions of the twentieth century tend to fixate on Fascism or Communism
and not on colonialism?

Answers

Answer:

Because most of the world was already colonized, so most of the political discussions were based on keeping control at home.

Fascism does not require a government-controlled command economy, whereas communism does. Because there is no private ownership of property or growth of money, both fascism and communism are classless societies. The state owns all means of production.

How was fascism or communism received during the 20th century?

Fascism is a nationalistic, top-down system with rigid class roles that is governed by an all-powerful dictator, in contrast to communism, which is based on the idea of economic equality and advocates for a classless society.

The early to mid-20th century saw the rise of fascism and communism, both of which had their inception in Europe. A political ideology that is autocratic is fascism.

On the other hand, socialism is a political philosophy in which members of a society own the production equipment. Over a nation, a fascist leader possesses absolute control and authority.

Socialist leaders, on the other hand, divide up authority and power among the states.

Briefly explain why there was a split in Islam that resulted in the creation of the two different sects.

Answers

Answer: It is not realy a "split". That would imply two relatively large groups. The fact is that at least 85% of those who call themselves Muslim are all from one group. They are the people who follow the Qur'an and the example of Prophet Muhammad (peace be upon him). They are called 'sunni' Muslims, by some people. In fact, they are simply true Muslims.

The other 15% are all deviant sects that have corrupted the true, original teachings. Anyone who studies Islam can see how the other groups have changed the original message.

Shiites, Ahmadiyyah, Alawi, Ismaili, Druze are some names of deviant groups.

In fact, Muhammad said that there would be such deviants; and he condemned their teachings as leading away from God. He said that the only rightly-guided group would be the one that stuck to the Qur'an and to his example. We thank God that it is the clear majority.

For an understanding of why the Shiite sect developed, you can go to Wikipedia for a detailed explanation. For examples of how they have gone astray from the healthy and true religion, you can go to You Tube and search: Real Shiah Faces.
