Answer:
[tex]\cos(2\theta) = 0[/tex]
Explanation:
Given
[tex]\sin(\theta) = -\frac{\sqrt 2}{2}[/tex]
[tex]270^o < \theta < 360^o[/tex]
Required
[tex]\cos(2\theta)[/tex]
Recall that:
[tex]\sin^2(\theta) + \cos^2(\theta) =1[/tex]
Substitute: [tex]\sin(\theta) = -\frac{\sqrt 2}{2}[/tex]
[tex](-\frac{\sqrt 2}{2})^2 + \cos^2(\theta) =1[/tex]
[tex]\frac{1}{2} + \cos^2(\theta) =1[/tex]
Collect like terms
[tex]\cos^2(\theta) =1-\frac{1}{2}[/tex]
[tex]\cos^2(\theta) =\frac{1}{2}[/tex]
[tex]\cos(2\theta)[/tex] is calculated as:
[tex]\cos(2\theta) = \cos^2(\theta) - \sin^2(\theta)[/tex]
So, we have:
[tex]\cos(2\theta) = \frac{1}{2} - (-\frac{\sqrt 2}{2})^2[/tex]
[tex]\cos(2\theta) = \frac{1}{2} - \frac{2}{4}[/tex]
[tex]\cos(2\theta) = \frac{1}{2} - \frac{1}{2}[/tex]
[tex]\cos(2\theta) = 0[/tex]

9. In addition to starvation and plague, what international
event devastated Europe in the fourteenth century?
A. The Avignon Papacy
B. The Hundred Years' War
C. The French and English War
D. The Crusades
Answer:the hundred year war
Explanation:
Answer:
B. The Hundred Years' War
Explanation:
It is a matter of the process of elimination: the Crusades ended before the 14th century began, and the Avignon Papacy was simply a relocation of the popes of Rome. Furthermore, the French and English War did not take place till the 1700s. As such, the only probable answer is the Hundred Years' War.
To further prove this answer, due to the Hundred Years' War almost all of England territory in France was lost, and many French nobles died. Additionally, it led to a decline in trade, particularly Gascon wine and English wool, which was a volatile part of Britain's trade goods. And to add salt to the wound, both countries taxed their people at great rates to pay for the war, causing social unrest.

What was the main message of The Wealth of Nations by Adam Smith?
O Food supplies would keep up as the population grew.
Food supplies would not keep up as the population grew.
The economy runs better with governmental involvement.
O The economy runs better without governmental involvement.
Answer:
The economy runs better without governmental involvement.
Explanation:
In the Wealth of Nations, Adam Smith lays out a very robust theory about how the economy works, this is why many economists consider him to be the Father of the economic science.
Adam Smith's main thesis was that people, acting own their own interest, were guided by the invisible hand, leading to positive results that benefited the whole of society, even if that was not the main goal of economic actors in first place (their main goal being furthering their own interests).
For this reason, Smith thought that most government intervention was unecessary, since according to him, economic actors tended to self regulate in the market, and to produce an optimal result for society. He did justify some government intervention though: in the military, in the judicial system, and in some basic social services in order to care for the poor, the elderly, and the sick.
excerpted from the speech Citizenship in a Republic The Man in the Arena By Theodore Roosevelt 1 It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat. Shame on the man of cultivated taste who permits refinement to develop into fastidiousness that unfits him for doing the rough work of a workaday world. Among the free peoples who govern themselves there is but a small field of usefulness open, for the men of cloistered life who shrink from contact with their fellows. Still less room is there for those who deride of slight what is done by those who actually bear the brunt of the day; nor yet for those others who always profess that they would like to take action, if only the conditions of life were not exactly what they actually are. The man who does nothing cuts the same sordid figure in the pages of history, whether he be a cynic, or fop, or voluptuary. There is little use for the being whose tepid soul knows nothing of great and generous emotion, of the high pride, the stern belief, the lofty enthusiasm, of the men who quell the storm and ride the thunder. Well for these men if they succeed; well also, though not so well, if they fail, given only that they have nobly ventured, and have put forth all their heart and strength. Select the correct answer.

What is citizenship?Citizenship is a person's commitment to a state. Each state chooses the circumstances in which it will recognize people as citizens and the circumstances in which that recognition will be revoked. A state's designation of a person as a citizen often entails the grant of civil, political, and social rights that are not available to non-citizens.
The right to a passport, the freedom to enter and exit the nation of citizenship, and the ability to reside in and engage in employment inside that country are generally seen as the fundamental rights that come with citizenship. While some nations allow residents to hold multiple citizenships, others require exclusive loyalty. There are several grounds for recognizing or granting citizenship to a person.

Why are immigrants coming to the United States now ?
Answer:
“[We are coming to the U.S.] because of the insecurity in our country. Because not enough jobs are being created there. So, we're coming for the American dream, and to ask for asylum. That is the dream we are carrying with us since we left with our families. I hope to God that we can achieve it, and we hope to God that we can,” Eduardo Josue, a Guatemalan migrant said.
The flow of migrants from Central and South America into the U.S. is rising. Many are unaccompanied minors fleeing poverty and instability.
The number of illegal crossings has been steadily rising since October 2020. But a recent spike in border crossings has Republicans warning Biden’s policies will lead to an immigration crisis. The Biden administration has acknowledged part of the reason more migrants are crossing the border is their immigration policy changes.

What is a clause?The fact that the sentence is structured to represent a complete and coherent concept makes it an independent clause. An independent clause expresses a complete thought with feelings connected and has a subject, a verb, and both a subject and a verb. The subject and working verb would not be present if it were a dependent sentence. The types of clause are main clauses, subordinate clauses, coordinate clauses and adjective clauses.

what does the term manifest destiny imply
Answer: Expansion from the Atlantic to the Pacific
Explanation:
The United States was originally 13 states on the Atlantic coast but today covers a vast area from the Atlantic to the Pacific. This is as a result of the Manifest Destiny mindset that engulfed America in the 18th and 19th century.
Those who subscribed to the Manifest Destiny believed that it was the destiny of the United States to stretch from the Eastern coast where the Atlantic was, to the Western Coast where the Pacific was.
As a result, Settlers went to the Western regions by their thousands and displaced natives, often violently, and took over their land as well as went to war with Mexico for the country to look as it does today.
