Question
The rate of growth of a certain cell culture is proportional to its size. In 10 hours a population of 1 million cells grew to 9 million. How large will the cell culture be after 15 hours?
Step 1
We know that the rate of growth is proportional to the size of the cell culture. This means that the growth can be represented by an exponential function of the form y = ab^x, where y is the size of the cell culture, x is the time in hours, a is the initial size Show more…

The rate of growth of a certain cell culture is proportional to its size. In 6 hours a population of 1 million cells grew to 7 million. How large will the cell culture be after 15 hours? The population of the cell culture after 15 hours will be million. (Round the final answer to the nearest million as needed. Round all intermediate values to the nearest thousandth as needed.)
The rate of growth of a certain cell culture is proportional to its size. In 8 hours a population of 1 million cells grew to 7 million. How large will the cell culture be after 20 hours? The population of the cell culture after 20 hours will be million. (Round the final answer to the nearest million as needed. Round all intermediate values to the nearest thousandth as needed.)
Involve exponential growth. Suppose a bacterial culture initially has 400 cells. After 1 hour, the population has increased to $800 .$ Find an equation for the population at any time. What will the population be after 10 hours?
