3. Since 1960, the growth in world population (in millions) closely fits the exponential function defined by A(t) = 3100eo1eor, where t is the number of years since 1960. Use the function to approximate 0.01661 world population in 2030.

Fund an exponential function such that f(1) = 3 and f(2) = 9

If the population of a Nigeria doubles in 9 years, find the growth rate k. Assume that the population increases exponentially.

The number of computers infected by a virus t days after it first appears usually increases exponentially. In 2009, the “Conflicker” worm spread from about 2.4 million computers on January 12 to about 3.2 million computers on January 13. A).Find the exponential growth rate k and write an equation for an exponential function that can be used to predict the number of computers infected t days after January 12, 2009.   B).Assuming exponential growth, estimate how long it took the Conflicker worm to infect 10 million computers.
