The diameter of a bacteria colony that doubles every hour is represented by the graph below. What is the diameter of the bacteria after 8 hours? 127 bacteria 255 bacteria 511 bacteria 1,023 bacteria
From the graph the diameter is modeled by d(t) = 2^t; where t is the number of hours. d(8) = 2^8 = 256 the diameter of the bacteria after 8 hours is 255 bacteria.
