Two quantities are measured with uncertainties, as follows: x = 8.01 ± 0.04 y = 6.23 ± 0.06 Calculate the values and uncertainties for the following functions, using error propagation rules. Express your results in scientific notation with the correct number of significant figures. (5 points each) You must show all work associated with your calculations and not just the correct answer! If you don’t, you’ll lose points! a) f = 4x – 5y b) g = x3y2 c) r = (x + y) / (2y-x) d) s = ((x2 + y) / x1/2 )3/2
