A slopped table top 2009-03-16 From anthony:A perfect circle with radius 100m is supported by four legs, 50m long. The circle is flat when all four legs are 50m long, and tilted when the legs are different in length. The four legs are spread evenly 90 degrees apart at 0, 90, 180, and 270. Find the high and low points in degree and height when the legs are 55m at 0 degree, 70m at 90 degree, 45m at 180 degree, and 30m at 270 degree. Not sure if they can be calculated using only 2 or 3 legs. I have tried by picking the two adjacent highest legs (55m and 70m) so I know the high point falls into the first quadrant. Then I tried using ratio to determine where the high point is, which I think high point should be closer to the 70m leg, I am not sure. If I can find the high point, the low point should be opposite to it.Answered by Chris Fisher and Harley Weston.     livinia the housefly finds herself caught in the oven 2006-06-27 From Danielle:livinia the housefly finds herself caught in the oven at the point (0,0,1). the temperature at the points in the oven is given by the function T(x,y,z) = 10 (xe(-y2) + ze(-x2)) where the units are in degrees celsius. (i.)so if livinia begins to move towards the point (2,3,1) at what rate in deg/cm does she find the temp. changing? (ii.)in what direction should she move in order to cool off as rapidly as possible? (iii.)suppose that livinia can fly at a speed of the square root of 2 (cm/sec.) if she moves in the direction of part (ii) at what rate will she find the temp. to be changing?
