We know
- Zeros to the right end of a number are not counted among significant figures
Hence number of significant figures is 2
Using an exponential function, it is found that the population of bacteria in the culture after 13 hours is of 1,491,747.
An <em>exponential function</em>, with a <u>doubling time of d, after t hours</u>, is given by:
- In which A(0) is the initial amount.
In this problem:
- The doubling time is of 3 hours, hence .
- The initial population is of 74000 bacteria, hence .
Then:
After 13 hours:
The population of bacteria in the culture after 13 hours is of 1,491,747.
