SUMMARY

The problem involves calculating the number of bacteria in a culture that starts with 1100 bacteria and doubles every hour for 12 hours. The formula used is 1100(2)^t, where t represents time in hours. The correct calculation for t=12 yields 4505600 bacteria, not 45056000 as initially stated. This highlights the importance of careful exponentiation in biological growth calculations.

PREREQUISITES
  • Understanding of exponential growth models
  • Basic algebra for manipulating equations
  • Familiarity with the concept of doubling time in biology
  • Knowledge of exponentiation notation, specifically using ** for powers
NEXT STEPS
  • Study exponential growth in biological systems
  • Learn about the implications of bacterial growth rates in microbiology
  • Explore the use of logarithms in solving exponential equations
  • Practice problems involving exponential functions and their applications
USEFUL FOR

Students studying biology, particularly microbiology, educators teaching exponential growth concepts, and anyone interested in mathematical modeling of population dynamics.

Homework Statement


A bacteria culture contains 1100 bacteria initially and doubles every hour.Find the number of bacteria after 12 hours. (This is a numerical answer; you can enter all of the digits or use exponential form with ** instead of ^ for exponentiation.)
n(12)
____ = bacteria

Homework Equations



1100(2)^t

The Attempt at a Solution



1100(2)^(12) = 45056000

Is this the correct answer?
Thank you[/B]

The left side is correct and the right side is wrong.
