Exponential Decay Cesium-137 is a radioisotope used in radiology where levels are measured in millicuries. Use the graph to give a reasonable estimate of the half-life of Cesium-137. 30 years

Exponential vs. Linear State whether each graph shows an exponential growth function, an exponential decay function, or neither. (a) Neither (b) (c) (d) Exp. Growth Exp. Decay Neither

Other Sequences Find the next term in the sequence: 1, 4, 9, 16, 25, … 36 Write an equation to describe the sequence. A(n) = n 2 Find the next term in the sequence: 1, 2, 4, 8, 16, 32, … 64 Write an equation to describe the sequence. A(n) = 2 n, starting at n = 0 Find the next term in the sequence: 1, 8, 27, 64, … 125 Write an equation to describe the sequence. A(n) = n 3

Other Sequences Find the 10 th term of the sequences below: * an = (2 n)2 a 10 = 400 * an = 2 n + 1 n 3 a 10 = 21 1000 * an = (2 n – 1)2 a 10 = 361

Other Sequences Find the fourth term of the sequence below: an = an – 1 + 10; a 1 = 29 a 4 = a 4 – 1 + 10 a 4 = a 3 + 10 Since we do not know what a 3 is, by the formula… a 3 = a 3 – 1 + 10 a 3 = a 2 + 10 Since we do not know what a 2 is, by the formula… a 2 = a 2 – 1 + 10 a 2 = a 1 + 10 a 2 = 29 + 10 a 2 = 39 a 3 = 49 a 3 = 59

Other Sequences Find the third term of the sequence below: an = an – 1 ∙ 2; a 1 = -1 Since we do not know what a 3 is, by the formula… a 3 = a 3 – 1 ∙ 2 a 3 = a 2 ∙ 2 Since we do not know what a 2 is, by the formula… a 2 = a 2 – 1 ∙ 2 a 2 = a 1 ∙ 2 a 2 = 2(-1) a 2 = -2 a 3 = -2(2) a 3 = -4
