Question 1 the temperature of a copper sphere cooling in air is measured as a function of time to yield the following data 2.0 146.0 129.5 114.8 82 0.6 temperature, t(°c) from theoretical considerations, an exponential decrease of temperature is expected as a function of time. one can assume a regression model given by t-aebt using data transformation, find the constant of the model, a. keep 4 decimal places.
