A species of beetles grows 41% every year. Suppose 100 beetles are released into a field construct an exponential model for this population. How many Beatles will there be in 9 years. How many Beatles will there be in 15 years. About when will there be 100,000 Beatles?

Write an exponential function for a population of 15,000 grows continuously at a rate of 2.5% per year

The news media of a city announced an important story at noon. At this time, 8% of the population had heard it. 3 hours later, 65% of the city's population had heard it. Assuming the logistic growth model, how long will it take for 99% of the city's people to hear the story? Round to 2 decimal places. hours

13 An experiment compares two bacterial cultures, both growing exponentially. Culture A begins with 1000 bacteria present at noon and at 2 p.m. there 1650 bacteria. Culture B also begins with 1000 bacteria, but is started at I p.m. and by 2 p.m. there are 1350 bacteria. Is there a time when the two cultures have the same number of bacteria?
