Bacteria in a petri dish is growing according to the equation $$ \frac{d P}{d t}=0.44 P \text {, } $$ where $P$ is the mass of the accumulated bacteria (measured in milligrams) after $t$ days. Suppose that the initial mass of the bacterial sample is $1.5 \mathrm{mg}$. Use a numerical solver to estimate the amount of bacteria after 10 days.

Key Concepts

Ordinary Differential Equations

These equations involve functions and their derivatives, used to model various phenomena such as growth, decay, or dynamic systems. They are fundamental in describing how a quantity changes with respect to another, typically time.

Exponential Growth Model

This concept refers to a process where the rate of change of a quantity is proportional to the current amount, leading to rapid increases over time. It is commonly used to model population growth, radioactive decay, and compound interest.

Initial Condition

An initial condition provides the starting value for the system described by a differential equation. It is essential for obtaining a unique solution that models the specific behavior of a system from a known starting state.

Numerical Methods

Numerical methods are techniques used to approximate solutions to mathematical problems, including differential equations, when analytical solutions are difficult or impossible to obtain. Methods such as Euler's or Runge-Kutta allow for estimating the evolution of the system over discrete time intervals.
