Analyze the zeros of f(x)=^4-3x^3-2x^2+3x-5

Determine the zeros to the nearest tenth.


a.1.4, -3.4

c.−1.2, 3.4

b.−2.4, 2.3

d.−1.4, 3.4

Answers

Answer 1

Answer:

d.−1.4, 3.4

Explanation:

Given

[tex]f(x) = x^4-3x^3-2x^2+3x-5[/tex]

Required

Determine the zeros

The best way to solve this is to apply the graphical method.

First, we plot the graph of: [tex]f(x) = x^4-3x^3-2x^2+3x-5[/tex]

See attachment

Next, we write out all values of x when the line crosses the y-axis.

From the attached graph, the points are (approximately):

[tex]x =-1.449[/tex]

[tex]x = 3.449[/tex]

Option (d) is the closest to the above values.

Hence, the zeros are: -1.4 and 3.4

Which is most often a result of a warm air mass moving over a cooler air mass

Answers

Answer:

When a warm air mass moves into an area of cooler air, the boundary between the air masses is called a warm front. The warmer, less-dense air slides up over the cooler, denser air in a wide, gentle slope. As the warm air cools, its relative humidity increases, and the water vapor condenses into clouds.

Explanation:

A warm air mass is made of lighter properties and is thus stable having low pressure and warm and hot air. The cold airmass is made of denser and cooler air.

The warm and cold front often leads to the formation of clouds and thunderstorms. The warm airmass being lighter moves over the colder air mass and hence creating rain. The cold air mass presents a zone of high pressure.

Hence the increase in precipitation is the result.

Describe the differences between the countries along the coast of Africa and the middle of the continent.

Answers

Answer:

Countries along the coast of Africa tend to be wealthier and more developed than countries in the middle of the continent, due to the natural, economic, and logistical advantages that having a coastlines provides for a country, for example, by making it easier for coastal countries to engage in international trade than it is for inland, landlocked countries.

Another difference is that countries along the coast of Africa tend to be more urbanized while countries in the middle of the continent tend to be more rural, precisely because the higher economic activity of the coastal countries fosters urbanization processes.

Reflecting on the treatment of Australia's aborigines, is Great Britain guilty of genocide?

Answers

Answer:

Yes, Great Britain is guilty of genocide, but we must clarify that this does not mean whatsoever that contemporary British or White Australian people are guilty as well, although they should of course know the acts of the past so that they are never repeated.

Explanation:

The reason why is that before the arrival of the British, there were more than 250,000 aboriginals living in Australia, and by 1920, the aboriginal population had gone down to 60,000. This sharp population decrease did not occur only due to involuntary causes like the spread of diseases, but also because of the many massacres that the British colonists committed against the aboriginals in order to take up their lands.
