(10 points) If two resistors with resistances R1 and R2 are connected in parallel, as in the figure, then the total resistance R, measured in Ohms (Q), is given by: 1 1 1 _ = _ + R R1 R; If R1 and R2 are increasing at rates of .3 9/8 and .2 9/3, respectively, how fast is R increasing when R1 = 80 Q and R2 = 100 9? 9/5 (10 points) Suppose that a point is moving along the path xy = 5 so that dy = 4. Find dx when x = 2. dt dt dx = dt
