  • @femtoamy
    @femtoamy 10 місяців тому

    Hmm, I came up with a purely geometrical argument. I imagined two line segments of length x (where x = 2 is the horizontal dimension of these rectangles) connected together by a pivot point that can otherwise move freely, and the right segment pinned to "the page" by another pivot point. The left segment must remain horizontal as the right segment can be swept upwards by an arbitrary angle, sweeping out an arc of radius = x. Thus one can manipulate this assembly to create the relevant aspects of the situation depicted in this problem. Because the left segment remains horizontal, the left edge of the left segment also sweeps out an arc of radius x. My initial question was, is the radius of the semicircle less than or greater than x? By visual inspection of how my system sweeps, I could see that if R > x or if R < x, there could never be a point "C" where the left end of the left segment intersects the semicircle. I can't really show this without a picture, but if you think about it, you'll see what I mean. Thus, R = x. Thus, the area of the semicircle is simply half the area of a circle of radius x = 2, which is pi*x^2 / 2 = 2 Pi.

    Hello sir, I am a self-learner. I need your help. Could you please help me with this question? Rachel is a keen runner. She is supposed to attend running training five days per week. Rachel finds that if she runs one day, the probability that she will run again the next day is 4\5. And if she does not run one day , the probability that she will not run the next day is 3\4. Suppose that Rachel runs one day: (a) What is the probability that she runs the next day? (b) What is the probability that she runs the day after that? (c) What is the probability that she runs exactly twice in the next three days? Answer from textbook is (a) = 4\5 (b) = 0.79 (c) = 0.31

      i think hes showing that the angle theta inside the triangle must =30, since the angle around the vectors =150 degrees. and 180-150 = 30. so by using -root 3, hesw proving that the angle to the vector in the opposite direction is 150 degrees, then the angle theta must be 30 degrees
