The expression below represents the number of bacteria in a petri dish after t hours. Interpret the meaning of the expression. A
. The initial number of bacteria is 57, and the growth rate is 3.1% per hour. B. The initial number of bacteria is 57, and the growth rate is 31% per hour. C. The initial number of bacteria is 131, and the growth rate is 5.7% per hour. D. The initial number of bacteria is 131, and the growth rate is 57% per hour.
To solve this problem what you should do is write an equation of the potential type. We have then that the generic equation is: y = A * (b) ^ t Where, y: number of bacteria after t hours. A: initial population of bacteria. b: growth rate of bacteria (b> 1) t: time (in hours for this case). Note: compare the given expression with the generic equation shown to find the answer.
