Suppose there are 30 bacteria in a Petri dish at start time. Seven hours later, there are 360 bacteria in the dish. 1.) Express the number of bacteria, P, as a function of \( t \) hours passed. Note: Round the growth rate to 4 dec. places. \( P(t)= \) 2.) Use the model from part a to determine the number of bacteria, rounded to a whole number, in the dish after 20 hours:
