  2. Test Topics!! Things to study!! Word Problems!!! Mixing Problems Soda-can Problem House Problem Bike Problem Rectangle Problems Be Smart!! If is say “Solve” vs. if it says “Solve using algebra”… • The quizzes!! • The HWs!! • Solving Rational Equations • Solving Rational Inequalities • Partial Fractions (A and B) • Sketching Rational Functions • Required items?!?

  3. Test Review Solve: Sketch a complete graph: • Solve: • Solve using algebra:

  4. Test Review Mixture Soda Can A cylindrical soda-pop can has radius r and height h. A manufacturer wishes to find the dimensions of the can with the minimum surface area. Find an algebraic representation for the surface area as a function of the height if the height is twice the radius. • There is 30 ounces of a pure substance. If you want to dilute it to have only a concentration of 35%, how much water must be added?
