Question:

Repeat Problem 53 for a starting colony of 1,000 bacteria such that a single bacterium divides every 0.25 hour.
Problem 53
A single cholera bacterium divides every 0.5 hour to produce two complete cholera bacteria. If we start with a colony of 5,000 bacteria, then after t hours, there will be
A(t)=5,000 • 22t = 5,000 • 4t
bacteria. Find A'(t), Aʹ(l), and A'(5), and interpret the results.
