Chapter 9 Radical Expressions and Equations Lesson 9-4b Radical Equations and Applications

Objective: The students will solve word problems involving radical equations.

Applications of Radicals

The time t for a pendulum of length L to go through one cycle is given by the formula: How long is the pendulum of a mantel clock with a period of 0.8 seconds? Answer: The pendulum is feet.

Example 2 – Dimensions of a Softball Diamond A softball diamond has 60-foot sides, as shown below. The catcher is 4 feet behind home plate. Estimate how far does the catcher has to throw to reach second base. 85 * Remember that the catcher has to throw from 4 feet more than x. The catcher has to throw about 89 feet. Answer: x2 = 602 + 602

Lesson Summary: Objective: The students will solve word problems involving radical equations.
