Advanced Placement (AP)

Answer:

Acid rain is responsible for severe environmental destruction across the world and occurs most commonly in the North Eastern United States, Eastern Europe and increasingly in parts of China and India. A buffer is a substance that accepts or donates hydrogen ions; it is used to counteract the effects of an acid.

Answer:

-In most parts of the world that are downwind from coal-burning facilities and from urban areas with large numbers of cars.

-A buffer is simply a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. Buffers work by reacting with any added acid or base to control the pH.

gayaneshka [121]
Everybody solves things differently. For me, I find that by writing everything down in my agenda, it helps me organize my thoughts and I'm able to visually see what assignment(s) are due soon.

Since your history exam is coming up, I would highly suggest you to study a bit each day. It's a bit of a stretch since May isn't even here yet, but it's better to start early. 

Once again, although May isn't here yet, I would suggest working on whatever is due in that month. Believe me, doing it last minute is seriously so stressful and you'll regret it. (I'm saying this from experience.)

Just remember to give yourself little breaks and be sure to have enough sleep! It's fine if there will be times where you find yourself staying up the whole night just to get your work done. But, don't do it often as that is not good for your health. 

Some tips for when you find yourself getting stressed out while working. I heard that tea, specifically Chamomile tea, helps reduce stress. Perhaps listening to music or taking a walk outside will help. 

I hope my tips help you at least a bit.

Describe one change that resulted from the developments illustrated by Grotius’ passage.
Finger [1]

Answer:

Question-Specific Scoring Guide

• One point for describing one piece of evidence that would support the Figes passage’s characterization

of Russia’s political culture prior to the Bolshevik Revolution.

• One point for describing one piece of evidence that would support the Figes passage’s interpretation of

Russia’s “new autocracy” in the 1920s and 1930s.

• One point for describing one piece of evidence that would undermine the author’s argument in the

passage that the “new autocracy” in Russia resembled the old.

Scoring Notes

To meet the requirement of “describe” in parts (a), (b), and (c), the response must offer a minimally accurate

description of a piece of evidence and some indication of how it relates to the task of the prompt. Although it is

not necessary for an acceptable response to offer an explicit explanation of the relationship between the

evidence offered and the task of the prompt, it must go beyond a mere mention or name-dropping (e.g., “Russia

had a history of tyrants in the Romanov dynasty” or “then Stalin happened”).

Possible acceptable responses for part (a) (not exhaustive):

• Russia’s lack of experience with democratic institutions (though the extent to which the Duma,

established after 1905, was “democratic” may be debated) prior to 1917 meant that its people were illprepared for the overthrow of the tsar or the Bolshevik takeover.

• The politically repressive nature of the tsarist government prior to 1917 gave democratic institutions

little or no chance to develop prior to the Revolution.

• Russia’s relative lack of economic and educational development prior to 1917 meant that the Russian

population as a whole was politically inexperienced and unsophisticated.

• Radicalization of the anti-tsarist opposition prior to 1917 meant that many opponents of the tsar were

not interested in democratic reform.

• Russia’s leaders were oblivious to “public opinion,” especially concerning a potential withdrawal from

World War I.

• Russia lacked mass-based political movements, such as those that led many other European states into

war between 1914 and 1916.

• The extent of women’s political participation and electoral suffrage lagged even further behind

Western Europe.

Additional notes:

• Responses that do not connect Russia’s historical experience pre-1917 to political institutions or to

“democratic culture” specifically will not earn the point. For example, some responses claim that

feudalism persisted in Russia until the Bolshevik Revolution, and others mention serfdom as an

economic institution, without addressing the political aspects of the prompt. Merely alluding to a policy

of Ivan the Terrible, Peter the Great, Catherine the Great, Nicholas I, or any other tsar will not earn the

point, unless it is directly related to the thwarting of a “democratic culture” in Russia.

• Note that “prior to the Bolshevik Revolution” should be interpreted as any period in Russian history,

including the months immediately prior to the Revolution.

What are the main features of pre-Columbian civilization in the Americas? How did they develop and change in response to Europea
anyanavicka [17]
The Pre-Columbian era incorporates all period subdivisions in the history and prehistory of the Americas before the appearance of significant European influences on the American continent, spanning the time of the original settlement in the Upper Paleolithic period to European colonization during the Early Modern period.

While the phrase "pre-Columbian era" literally refers only to the time preceding Christopher Columbus's voyages of 1492, in practice the phrase is usually used to denote the entire history of indigenous Americas cultures until those cultures were exterminated, diminished, or extensively altered by Europeans, even if this happened decades or centuries after Columbus's first landing. For this reason the alternative terms of Precontact Americas, Pre-Colonial Americas or Prehistoric Americas are also in use. In areas of Latin America the term usually used is Pre-Hispanic.

1) Calcula la diagonales de un poligono n lados. Heptágono: 2 puntos
ahrayia [7]

Answer:

El número de diagonales de un polígono de n lados se calcula mediante la siguiente fórmula:

d = \frac{n\cdot (n-3)}{2} (1)

Donde:

d - Cantidad de diagonales del polígono.

n - Cantidad de lados del polígono.

Bajo esta fórmula, tenemos los siguientes resultados:

a) El heptágono tiene 14 diagonales.

b) El octágono tiene 20 diagonales.

c) El eneágono tiene 27 diagonales.

d) El decágono tiene 35 diagonales.

e) El pentadecágono tiene 90 diagonales.

Explanation:

La cantidad de diagonales de un polígono se puede determinar mediante la siguiente ecuación:

d = \frac{n\cdot (n-3)}{2} (1)

Donde:

d - Cantidad de diagonales del polígono.

n - Cantidad de lados del polígono.

A continuación, calculamos la cantidad de diagonales de los siguientes polígonos:

Heptágono (n = 7)

d = \frac{7\cdot (7-3)}{2}

d = 14

El heptágono tiene 14 diagonales.

Octágono (n = 8)

d = \frac{8\cdot (8-3)}{2}

d = 20

El octágono tiene 20 diagonales.

Eneágono (n = 9)

d = \frac{9\cdot (9-3)}{2}

d = 27

El eneágono tiene 27 diagonales.

Decágono (n = 10)

d = \frac{10\cdot (10-3)}{2}

d = 35

El decágono tiene 35 diagonales.

Pentadecágono (n = 15)

d = \frac{15\cdot (15-3)}{2}

d = 90

El pentadecágono tiene 90 diagonales.
