MATH 111 Final: MATH 111 UW Winter 17 Final Solution
Document Summary
Solutions to math 111 final exam winter 2017. 1. (a) 40 kilometers per hour (b) t = 5 hours (c) [0. 5, 2. 5] (d) 0. 9 hours. Av c. f c = 30. (e) m c = m r = 20 when q = 5. 5. Then, t r = 110 thousand, t c = 5. 5 14. 3 = 78. 73 thousand so the pro t is 31. 27 thousand. 3. (a) f opens up because 0. 4 > 0. (b) f increases after x = 2. 8. g decreases after x = 4. 2. 4 x = (b) 1. 43 = (1. 03)7x 1. 0. 27 (c) 0. 3 = 2. 4 ln(3 + 2. 1x) ln(1. 3861) = ln(1. 03)7x = 7x ln(1. 03) x = ln(1. 3861. = ln(3 + 2. 1x) e0. 125 = 3 + 2. 1x e0. 125 3. 5. (a) t r = 2 4. 20 = 8. 40. V c = 2 av c(2) = 7. 12 so t c = 8. 52.
