Dr. Lee’s student is measuring the temperature drop of hot water under ambient (room temperature) condition. Based on the data, he made the best fit curve, Y[F]=A×eBt+C where, t is time in minute, A=100.0, B=-1.0, and C=50.0. He wants to linearize the best fit curve in the form of, zi[F]=a×ti+b. Find coefficients a and b, and calculate z when the time t is at 2 min. Answer up to 1 decimal places (e. g., 0.1), and put the right unit. If necessary, round off. Time [minute] Temperature [F] 0 150.0 1 86.8 2 63.5 3 55.0 4 51.8 5 50.7 a= b= z (at t=2s) =
