The second planet from the sun bakes under twice as much solar radiation as Earth and reaches temperatures of 895 degrees Fahrenheit (480 degrees Celsius).Pressure from the dense atmosphere of sulfuric acid gas is about 95 times greater than Earth's and would crush a human. The thick cloud cover around Venus rotates much faster than the planet itself - once every four days.
The surface of Venus is mostly a rocky desert (this computer-generated view shows lava flows around Sif Mons). Like Mercury, Earth and Mars, Venus is composed of mostly rock and metal.
The Greeks believed Venus was two separate objects - one in the morning sky and another in the evening. After the moon, Venus is the brightest object in the sky. Because it is often brighter than any other object in the sky - except for the sun and moon - Venus has generated many UFO reports.While all of the planets orbit in an ellipse, Venus' orbit is the closest to a perfect circle. It is the only planet in the solar system whose day (241 Earth days) is longer than its year (225 Earth days).
Поверхность Венеры в основном представляет собой каменистую пустыню (на этом компьютерном изображении показаны потоки лавы вокруг Сиф Монса). Как Меркурий, Земля и Марс, Венера состоит в основном из рока и металла.
Греки считали, что Венера - это два отдельных объекта: один в утреннем небе, а другой - в вечернем. После Луны Венера - самый яркий объект на небе. Поскольку она часто ярче, чем любой другой объект на небе, за исключением Солнца и Луны, Венера стала источником множества сообщений об НЛО. В то время как все планеты вращаются по эллипсу, орбита Венеры наиболее близка к идеальному кругу. Это единственная планета в Солнечной системе, у которой день (241 земной день) длиннее ее года (225 земных дней).
получается делаем так:
сначала решаем уравнение как и обычно т.е. теоремой виетта или дискриминантом
х^2-4х+3=0
я решу теоремой виетта:
сумма корней равна 4
произведение 3
значит корни 1 и 3
далее:
есть такая формула разложение на множетели квадратного уравнения выглядит так: a(x-x1)(x-x2), где а-множетель перед квадратом в нашем случае это 1, х1 и х2 - корни.
подставим в неё наши корни, получим (x-1)(x-3)=0
так а теперь решим это неравенство (x-1)(x-3)> 0
методом интегралов ( тут 3 промежутка от минус бесконечности до 1 от 1 до 3 и от 3 до плюс бесконечности):
допустим х =0, подставим (0-1)(0-3)=3 знак + значит в промежутке от минус бесконечности до 1 знак +
от 1 до 3 знак -
от 3 до плюс бесконечности +
ответ: х принадлежит промежутку от минус бесконечности до 1 и от 3 до плюс бесконечности

Sochi 2014
Winter Olympic games 2014 (XXII winter Olympic games is an international sporting event, held from 7 to 23 February 2014 in the Russian city of Sochi.
The choice of city
June 22, 2006 IOC President Jacques Rogge of the seven claiming bids (Jaca, Alma-ATA, Sofia, Borjomi, Sochi, Salzburg Pyeongchang) announced the names of three candidates. They are Sochi, Salzburg and Pyeongchang.
4 July 2007 in Guatemala held the 119th IOC session, which was chosen as host city of the Olympics.
Before the vote, presentations of candidate cities. Sochi athletes represented: Svetlana Zhurova, Evgeny Plushenko, Mikhail Terentiev (Paralympic) and Alexander Popov; sports officials: Vyacheslav Fetisov, Elena Anikina, Shamil Tarpischev, Dmitry Chernyshenko and Vitaly Smirnov; policy: Vladimir Putin, Alexander Zhukov, German Gref, Alexander Tkachev, Viktor Kolodyazhny.
In the first round of voting, which was attended by 97 participants-representatives of the countries of the IOC, has left Salzburg. In the second round won Sochi winning the Pyeongchang 4 votes (51 vs. 47). Thus Russia became the first host of the Winter Olympic games.

Chose talismans with work and adventures. Several votes were declared invalid, the winning options were rejected, the timing of the vote was postponed.
The final voting results were as follows:
Leopard (author Vadim Pak, , Nakhodka) to 28.2% of the votes
White Bear (author Oleg Heart, , Sochi) - 18.3% of the votes
Bunny (author Silvia Petrova, village of New Buyanova, Anticosti region, Chuvashia) - 16.4% of the votes.
The mascots of the Olympic Winter games 2014
The choice was criticized. In particular, it was noted that the composition of the Sochi mascots (the Leopard, polar Bear and Bunny) is almost identical to the Trinity of the mascots for the Olympic games in salt lake city (Coyote, Bear and Rabbit). Graphic design White Bears in General, and especially of the muzzle and a large round head, more typical for brown bears than for whites, in which the head is elongated. It is also noted close to plagiarism similarity White Bears with the mascot of the Moscow summer Olympics in 1980 bear Misha, as indicated, and the Creator of the image of the last Victor Chizhikov.
The world wildlife Fund in Russia suggested Organizing Committee "Sochi 2014" to edit the picture with Leopard, explaining that the fur is depicted animal is not like leopard, and snow leopard, which in the Caucasus had never dwelt.
Olympic torch relay
Olympic torch relay "Sochi 2014" is the longest and most ambitious in the history of the winter Olympic games. Started it October 7, 2013 and will end on the opening day of the Olympics on 7 February 2014.
The route of the Olympic flame in Russia was presented by the organizing Committee "Sochi 2014" exactly one year before the start of the relay. Within 123 days the torch of the Games in the hands of the athletes will make more than 65 thousand miles on cars, trains, airplanes, and Russian Troika and reindeer eyes 130 million inhabitants 2900 settlements of Russia, will visit the capitals of all 83 subjects of the Russian Federation
