Sociologists have found that information spreads among a population at an exponential rate. Suppose that the function y=525(1e0.038t) models the number of people in a town of 525 people who have heard news within t hours of its distribution. Graph the function on a graphing calculator. When will 90% of the people have heart about the grocery store opening?

Step 1
Determine the 90% of the people on the town:
=0.9×525=472.5
then graph y=472.5
the x coordinate of intersection point represent the time required for the 90% to hear the opening
conclude that t61 hour

The population of California was 29.76 million in 1990 and 33.87 million in 2000. Assume that the population grows exponentially.
(a) Find a function that models the population t years after 1990.
(b) Find the time required for the population to double.
(c) Use the function from part (a) to predict the population of California in the year 2010. Look up California’s actual population in 2010, and compare.
