A culture of bacteria starts with 40 bacteria and increases exponentially.
The relationship between B, the number of bacteria in
the culture, and d, the elapsed time, in days, is
modeled by the following equation.
d
B= 40(10) 1.5
In how many days will the number of bacteria in the
culture reach 1,000,000 ?
