Introduction

In the field of mathematics, particularly in the realm of differential equations, the study of population growth is a crucial aspect. The growth of a bacterial population is a classic example of exponential growth, where the population size increases at an accelerating rate. In this article, we will delve into the world of bacterial population growth, specifically focusing on the size of a bacterial population at time $t$ (measured in hours) given by the equation $B(t) = 1000(1 + 0.6t)$ .

The Bacterial Population Equation

The equation $B(t) = 1000(1 + 0.6t)$ represents the size of the bacterial population at time $t$ . Here, $B(t)$ is the population size at time $t$ , and $t$ is measured in hours. The equation is a linear function, indicating that the population size increases at a constant rate.

Determining the Increment in B

To determine the increment in $B$ when $t = 3$ and $\Delta t = 1$ , we need to understand the concept of an increment. An increment is the change in a function's value over a small interval. In this case, we want to find the change in $B$ when $t$ increases from 3 to 4.

Calculating the Increment

To calculate the increment in $B$ , we need to find the difference between the population sizes at $t = 3$ and $t = 4$ . We can do this by plugging in the values of $t$ into the equation $B(t) = 1000(1 + 0.6t)$ .

Step 1: Find the population size at $t = 3$

import numpy as np
def B(t):
return 1000 * (1 + 0.6 * t)
B_3 = B(3)
print("Population size at t = 3:", B_3)

Step 2: Find the population size at $t = 4$

# Find the population size at t = 4
B_4 = B(4)
print("Population size at t = 4:", B_4)

Step 3: Calculate the increment in $B$

# Calculate the increment in B
increment_B = B_4 - B_3
print("Increment in B:", increment_B)

Conclusion

In this article, we explored the growth of a bacterial population using the equation $B(t) = 1000(1 + 0.6t)$ . We determined the increment in $B$ when $t = 3$ and $\Delta t = 1$ by calculating the difference between the population sizes at $t = 3$ and $t = 4$ . The increment in $B$ represents the change in the population size over a small interval, providing valuable insights into the growth of the bacterial population.
