A colony of bacteria is growing exponentially according to the function below, where T is in hours. How many bacteria are there after 7 hours?
B(T)= 4*e^(0.8)T

  • Math- Alg 2 -

    B(T)=4*e^(0.8)(7)
    7 for T
    B(T)=62.3151
    (plugged the equation into a graphing calculator)

    That is completely wrong. I'm sure you didn't type the equation in right or something. The correct answer is 1081-1082 bacteria.
