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) =

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
