(a-b) (a+b) = a^2 - b^2
so 1.05 = 1 + 0.5 and 9.5 = 1 - 0.5
1.05 * 9.5 = (1 + 0.5) (1 - 0.5) = (1)^2 - (0.5)^2 = 1-(0.25) = 0.75
Hope you got it!!!!!
I dont think it was that difficult to post it here.... actually it depends on your class.....

2Sorry for such a messy answer but i didnt have much time so made it very fast
ok now so assuming that you know the intercept form of straight line ... you can find the intercept as shown in figure
now you have to draw the line y= (-1) and also find the equation of perpendicular bisector of AB
as it is the bisector ... we can apply mid point formula and as it is perpendicular we know that =
slope of(perpendicular bisector) = -1/(slope of AB)
find slope of AB and then find slope of perpendicular bisector
NOW as you know one point and the slope ... you can find the equation of perpendicular bisector
as it intersects y=(-1) line put y=(-1) in equation of perpendicular bisector and find x cordinate of C
leaving the calculation part to you ... you just have to calculate the area of ABC as each coordinate is there waiting for you
Hope you got it!!!!
And sorry for such a long post Again

2Up to the end of the 19th century, Russia was an autocratic country. It was ruled by an autocratic Czar. He ruled as he liked. His will was the sole source of law, of taxation and justice. He controlled the army and all the officials. Through his special position on the Holy Synod, he controlled even religious affairs. His autocratic rule was supported by the privileged nobles, who possessed land and serfs, and held all the chief offices in the Czar's administration.
The mass of people were serfs. Serfs were 'slaves'. They worked on the estates of the nobles. They could be punished in any form by the nobles. They could even be sold as chattels by the nobles. Besides the serfs, there was a very small middle class in the towns. They were discontented with the backwardness of Russia.
The main theme of the Russian history in the 19th century is that the non-noble classes asked for an improvement in their wretched and poor conditions of life. When the Czarist government failed to do so, they revolted for the first time in 1905 and then for the second time in 1917, by which Czardom was finally overthrown.
The causes of the 1905 Revolution went far back into Russian history. It was the product of more than a century of discontent and the discontent grew more rapidly after 1861.
CAUSES OF THE 1905 REVOLUTION
A. THE REIGN OF CZAR ALEXANDER II ( 1855-1881 ) AND WIDESPREAD DISCONTENT AMONG THE RUSSIANS
Czar Alexander II began his reign in 1855 when Russia was defeated by Britain, France and Piedmont in the Crimean War. He thought that the chief reason for Russian defeat was her backward economic and social system -- most of the labour force were serfs who were ignorant and superstitious. In order to strengthen the dynasty, he decided to carry out a number of reforms to modernize the archaic institutions of Russia.
2Causes of the French Revolution
Political and Social Inequalities
France still practised feudalism in the 18th century. The nobles and clergy enjoyed special privileges. They did not have to pay taxes. The common people did not have power and freedom in politics. They worked hard and had to pay heavy taxes. The nobles and clergy made up the First and Second Estates in the Estates General. The common people (i.e. the middle class (bourgeoisie), peasants and artisans) made up the Third Estate. The nobles and clergy could outvote the common people easily though the Estates General was always not called by the king, who ruled as an absolute monarch. The common people became discontented with the privileged classes.
Bankruptcy of the Government
Louis XIV had spent too much. His successors did not cut down expenses. Louis XVI also failed to improve the financial situation. He dismissed ministers who tried to introduce financial reforms. By 1789, the government was bankrupt.
Influence of the Enlightenment and the American Revolution
The ideas and writings of Enlightenment thinkers like Montesquieu, Voltaire, and Rousseau became widespread. The French people were inspired to go against their king.
The suucess of the Americans to overthrow British rule encouraged the French to fight for their freedom.
Outbreak of revolution 1789
When Louis XVI finally called the Estates General to solve financial difficulties, the Third Estate did not agree with the unfair system of the Estates General. They formed the National Assembly to make a constitution. People were afraid that the king would suppress the National Assembly. They were also discontented that the king dismissed Necker, the popular Finance Minister. The hungry Parisians, who suffered from bad harvest, burst out their anger by attacking the Bastille prison (for political prisoners). The Fall of Bastille started the French Revolution. It spread out to other parts of France.
