Algebra 2 is a comprehensive textbook that builds on essential algebraic principles by guiding students from foundational first-degree equations and inequalities to more complex topics such as systems of equations, matrix operations, and quadratic and radical equations. It emphasizes the application of mathematical techniques like substitution, elimination, and graphing to translate real-world problems into solvable algebraic models. The book further explores vital areas including exponential-logarithmic functions, conic sections, probability, statistics, and trigonometry, equipping learners with diverse analytical tools. Additionally, a dedicated focus on trigonometric graphs and identities ensures that students understand how parameters like amplitude, period, and phase shift govern periodic phenomena, reinforcing the text's broad utility in both academic and practical contexts.

Problem 5
POLICE Police use blood alcohol content (BAC) to measure the percent concentration of alcohol in a person's bloodstream. In most states, a BAC of 0.08 percent means a person is not allowed to drive. Each hour after drinking, a person's BAC may decrease by 15$\% .$ If a person has a BAC of 0.18 , how many hours will he need to wait until he can legally drive?
