Homework Check • Court Case: C = 22, k = -.007753359 • Prosecutors – Interpreting the last bullet as feeling totally better with a temp. of 98.6, then time of death would be 3:13, which is after Steve’s alibi. • Defenders – Interpreting the last bullet as still feeling sick, with a temp. of anything higher than 99.3, then time of death would be before 3:10 while Steve had an alibi. • 53.382 min total or 42.382 min after the temp was 275. • 379.236 • 3:49 am

  2. Review • Properties of Logs: • ln 1 and log 1 = 0 • lne = 1 • logbb = 1 • elnx = x • blogbx = x • Change of Base:

  3. Review Rules for Expanding & Condensing Product Rule: Quotient Rule: Power Rule: • How to solve for x: • Getting single log and solve. • Getting e alone and solve. • Circle method or log/ln or e both sides.

  4. Review • Applications (graphically & algebraically) • Population A(n) = P0(1 ± r)n • Half & Double Life A(n) = P0(1/2)n/hl A(n) = P0(2)n/dl • Compound interest A(t) = P0(1 + r/n)nt • Compound continuously A(t) = Pert • Newton’s Law of Cooling T = Cekt + R

  5. Review • 4 Stations are set up with the answers to the review worksheet. • Working individually, work out the problems in any order, then check your answers as you go. • If you get stuck, look in your notes or borrow a book to try to find the answer. • Still no luck? Go take a look (without your pencil) at the answer to figure it out. • When finished look at the suggested review problems in the book and make sure you understand the material from the quizzes. • pg 345 #19, 21, 27-33 odd, 43 – 49 odd, 53 – 57 odd, 63, 65, 69, 75 – 79 odd and 95
