P(t)=7e^(t/4) Your computer continues with a note from the files that the alien civilization performed these calculations on the linearization of P(t). Therefore, you will need to linearize P(t) and then use that model to determine when to remove the light source to have 7.21 million bacteria. Your linerization should be around t=0, since this is the time when the light source is switched on. Part B.) Using this linearization, after how many minutes (to three decimal spaces) will you turn off the light to generate a population of 7.21 million bacteria?
