A fruit fly population of 24 flies is in a closed container. The number of flies grows exponentially, reaching 384 in 18 days. When the population grow to 48? Write an equation that models this scenario.

The equation M(a) = 2.1a 2 + 1.7a + 16.5 models the population, in millions of a country. If a represents the number of years, what is the estimated population after seven years?

A bacteria culture starts with 100 bacteria and grows exponentially, after 1 hour the population is 460. find the equation that gives the number of bacteria as a function of hours. in how long will there be 5000 bacteria?

You add 6 paramecia to a test tube and feed them bacteria. One week  later the population has grown to 15. Assuming that the population is growing exponentially, how many paramecia can you expect after 7 weeks? Round your answer to the closest full number.

Using U.S. Bureau of Labor Statistics data for selected years from 1950 and projected to 2050, the number of men in the U.S. workforce(in millions) can be approximated by ? = 0.59? + 43.2 where x equals the number of years past 1950. Find the projected number of men in the U.S. workforce in 2050 according to this model.
