# Ch 1: Mathematical Modeling

Use the following video lessons and quizzes to learn about mathematical modeling and how to write and evaluate them. These easy-to-follow lessons are just a portion of our online study guide and video collection.

## Mathematical Models - Chapter Summary and Learning Objectives

Mathematical models are used to explain the properties of various systems and figures. In the lessons in this chapter, our instructors will show you how to write and evaluate algebraic expressions for two-dimensional figures. Another lesson demonstrates the use of systems of linear equations to evaluate economic functions and profit functions. You will learn to find the minimum and maximum values of quadratic models, too. Instructors use examples from real life regarding cost determination and distance to show you how to write and evaluate linear models. By the end of this chapter, you should have a solid understanding of topics including:

• Writing equations that relate a two-dimensional figure's side lengths, perimeter and area
• Writing real-life linear models
• Applying linear equations to economic functions
• Determining minimum and maximum values of quadratic models
