#### Solutions

Chapter 1, Problem 5RCC
To determine

## To define: A mathematical model.

Expert Solution

Solution:

Mathematical model is an equation or a function of the real world problems. Describing the real life problems using mathematical expressions is called mathematical model.

### Explanation of Solution

Mathematical model is an equation or a function of the real world problems. Describing the real life problems using mathematical expressions is called mathematical model.

Anyone can able to understand the situation represented using mathematical expressions than describing in words. From a mathematical model, it is easy to observe the pattern and predict the upcoming behavior of the function/equation.

Example:

The length of the rectangle is 2 more than its breadth.

The above description can be modeled as follows.

Let the length of the rectangle be l and the breadth be b.

Then, according to the description, l=b+2.

Thus, it is easy to calculate the value of breadth for any length l.
