A large region of forest has been infested with gypsy moths. The region is roughly triangular, as shown in the figure. From the northernmost vertex of the region, the distances to the other vertices are 25 miles south and 10 miles east (for vertex ), and 20 miles south and 28 miles east (for vertex ). Use a graphing utility to approximate the number of square miles in this region.

7.4 Exponential and Logarithmic Equations Copyright © Cengage Learning. All rights reserved. Introduction There are two basic strategies for solving exponential or logarithmic equations. The first is based on the One-to-One Properties and the second is based on the Inverse Properties. One-to-One Properties a = a if and only if x = y. logax = log a if and only if x = y. Inverse Properties a loa = x log a = x 2 Solving Simple Equations 3 Introduction 4 Example 1 Solve for x. a) 64 3x ▯ 32 2
