= 4. [T] If two electrical resistors are connected in parallel, the total resistance (measured in ohms, denoted by the Greek capital letter omega, 2) is given by the equation 1 + 1. If R, is increasing at a rate of 0.5 12/min R R1 R2 and R2 decreases at a rate of 1.182/min, at what rate does the total resistance change when R1 = 2012 and R2 = = 5092/min? =
