The following data represent the world population. An ecologist is interested in building a model that describes the world population. Year Population (in Billions) 2001 2002 2003 2004 2005 2006 2007 6.17 6.25 6.32 6.40 6.48 6.55 2008 2010 6.85 2009 6.63 6.71 6.79 Source: U.S. Census Bureau (a) Using a graphing utility, draw a scatter diagram of the data using years since 2000 as the independent variable and population as the dependent variable. (b) Using a graphing utility, build a logistic model from the data. (c) Using a graphing utility, draw the function found in part (b) on the scatter diagram. (d) Based on the function found in part (b), what is the carrying capacity of the world? (e) Use the function found in part (b) to predict the population of the world in 2015. (f) When will world population be 10 billion?

Geog 240 09/27/2016 ▯ The shape of the earth and geodesy ▯ Geodesy enables absolute definitions (vs relative definitions) Relative elevation (this mountain is 400 feet higher than that one) Absolute elevation (this mountain is 400 feet above a commonly accepted datum) ▯ Who uses geodesy Geographers, geologists, oceanographers, meteorologists, and even paleontologists use geodesy to understand physical processes on, above, and within earth Because geodesy now can make extremely precise measurements ( to the centimeter), scientists use its results to determine exactly how much earths
