Average Life Span One reason for the increase in human life span aver the years has been the advances in medical technology. The avemge life span for American women from 1907 through 2007 is given by w(t) = 49.9 + 17.1ln(t) (1 s t s 5) where w(t) is measured in years and t is measured in ZOcyear intervals, with t - 1 corresponding to 19071 (Round your answers to one decimal place.)

MY NOTES ASK YOUR TEACHER Magnitude of Earthquakes On the Richter scale, the magnitude R of an earthquake is given by the formula R = 109(70) where I is the intensity of the earthquake being measured and I is the standard reference intensity. (a) Express the intensity I of an earthquake of magnitude R = 3 in terms of the standard intensity Io. 1 = (b) Express the intensity I of an earthquake of magnitude R = 8 in terms of the standard intensity Io. I = How many times greater is the intensity of an earthquake of magnitude 8 than one of magnitude 3? times greater (c) In modern times, the greatest loss of life attributable to an earthquake occurred in Haiti in 2010. Known as the Haiti earthquake, it registered 7.0 on the Richter scale. How does the intensity of this earthquake compare with the intensity of an earthquake of magnitude R = 3? Need Help?

If it is false, give an example to show why it is false. The function f(x) = In ( x ) - is continuous on (1, co). True. f(x) is greater than one on (1, co). Therefore, it is continuous on (1, co). True. g(x) = In(x) is continuous and greater than zero on (1, co). Therefore, f(x) = - In (x ) is continuous on (1, co). False. g(x) = In(x) is not continuous on (1, co). Therefore, f(x) = ] is not continuous on (1, co). False. g(x) is undefined on (-co, 0). Therefore, f(x) = T In (x ) is not continuous on (1, co). False. f(x) is undefined at x = 0. Therefore, it is not continuous on (1, co). Need Help? Read It
