The population of the world, P (in billions), is well-approximated by the function P = 5.6(1.0117)t , where t represents the number of years after the beginning of 1994. (a) What is the population of the world at the beginning of 1999? How fast is the population of the world growing at the beginning of 1999? Include units, and make it clear which answer is which. g
