  1. Warm Up 9.17 • Evaluate the following. 1. h(x) = 18 – 2|2x + 4|, h() 2. g(x) = -, g(11) Simplify 3. 4.

  2. Warm Up 9.17 • Evaluate the following. 1. h(x) = 18 – 2|2x + 4|, h() 2. g(x) = -, g(11)

  3. Warm Up 9.17 • Simplify 3. 4.

  4. Warm Up 9.18 • 1. The sum of the interior angles of a triangle is 180º, of a quadrilateral is 360º and of a pentagon is 540º.  Assuming this pattern continues, find the sum of the interior angles of a octagon (8 sides). • 2. A culture of bacteria triples every 2 hours. If there are 250 bacteria at the beginning, how many bacteria will there be after 12 hours? 1080 60,750

  5. Answers • The sum of the interior angles of a triangle is 180º, of a quadrilateral is 360º and of a pentagon is 540º.  Assuming this pattern continues, find the sum of the interior angles of a octagon (8 sides). Equation: an = a1 + d(n-1) a1= 180, d = 180, n = 6 Arithmetic Geometric 900 7 5 720 6 4 180 3 1 1080 8 6 360 4 2 540 5 3

  6. This is geometric sequence with a common ratio of 3 The number of hours, however, is arithmetic with common difference of 2. Which term number is 12? • A culture of bacteria triples every 2 hours. If there are 250 bacteria at the beginning, how many bacteria will there be after 12 hours? Arithmetic = 2hrs = 12 Plug it in! 12 n = 6 Geometric = 250 = 3 n = ? Plug it in! = 60750
