Explanation:

0.31x0.31 + 1.81x1.81 - 2 x 0.5611 = (0.31)^2+(1.81)^2 - 2 x (0.31) x (1.81) = (1.81 - 0.31)^2 =(1.5)^2=2.25 Formula reference : a^2 + b^2 - 2 x a x b = ( a - b )^2


For years now, George W. Bush has told Americans that he would increase the number of troops in Iraq only if, the commanders on the ground asked him to do so. It was not a throw away live. Bush said it from the very first days of the war, when he and pentagon boss Donald Rumsfeld were criticized for going to war with too few troops. He said it right up until last summer, stressing at a news conference in Chicago that Iraq commander General George Casey will make the decisions as to how many troops we have there. Seasoned military people suspected that the line was a dodge that the civilians who ran the pentagon were testing their personal theory that war can be fought on the cheap and the brass simply knew better than to ask for more in any case the president repeated the mantra to dismiss any suggestion that the war was going badly. Who, after all, knew better than the generals on the ground? Now as the war nears the end of its fourth year and the number of Americans killed has surpassed 3,000 Bush has dropped the generals know best line sometime next week the president is expected to propose a surge in the number of 45 forces in Iraq for a period of up to two years. A senior official said reinforcements numbering about 20,000 troops and may be more could be in place within months; the surge would be achieved by extending the stay of some forces already in Iraq and accelerating the deployment of others. The irony is that while the generals would have liked more troops in the past, they are cool to the idea of spending more now that’s in past because the politicians and commanders had trouble agreeing on what the goal of a surge would further erode the readiness of the US’s already stressed ground forces and even those who back a surge are under no illusions about what it would mean to the casualty rate. If you put more American troops on the front line said a white house official, you’re going to have more casualties. Coming from Bush, a man known for bold strokes the surge is a strange half-measure- too large for the political climate at house too small to crush the insurgency in Iraq and surely three years too late Bush has waved off a bipartisan rescue mission out of pride stubbornness or ideology or same combination of the three, Rather than reversing course, as all the wise elders of the Iraq study group advised, the commander in chief is betting that more troops will lead the way to what one white house official calls “victory.”

If citizens can not have the right to commit suicide, they cannot be allowed to stay in an atmosphere full of smoke because that might cause certain chronic disease leading to their unnatural death. Thus, there should be a complete ban on smoking in all the public places across the country. The recent Supreme Court order banning smoking in public places is not restricted to a few metropolitan towns; it must be enforced in all the villages and cities. The three-page order contains certain statements of facts. ?Fundamental right guaranteed under Article 21, of the Constitution provides that none shall be deprived of his life without due process law. Than why a non-smoker should be afflicted by various diseases including lung cancer or of heart only because he is required to go to public places?? Some time back when the court ruled that suicide was unconstitutional and illegal, it had referred to Article 21, which says that State alone has the right to deprive a citizen of his life, but with due process of law. Thus inhaling of smoke by passive smokers has been equated with commission of suicide, an act prohibited under law. But when a person who makes an unsuccessful attempt to commit is liable to face criminal prosecution which man end in his conviction, a passive smoker, however, is immune from any penal action. If one is made to inhale smoke for no fault of his and also against his wishes, the perpetrator of offence of smoking gets away with a nominal fine for such a grave offence that costs the exchequer Rs. 13,500 crore annually in terms of loss of productivity. According to WHO report, smoking may kill seven million people annually. During the last half century, smoking killed more than 10 million people in the developing countries alone. The court also felt that the persons not indulging in smoking cannot be compelled to or subjected to passive smoking on account of acts of the smokers. The ban on smoking order is judicial intervention, and not an activism.
