Open one of the computer algebra systems below to follow along with this module. Suppose that the population growth for a particular city can be described by an exponential model and that the population was 4,000,000 in 1990 and 4,200,000 in 1994. The graph below shows the height of a bouncing ball. Measure the height of the ball at the top of each bounce. If so, predict the height of the ball for the next three bounces.
Some atoms are unstable and spontaneously emit radiation and change into different atoms.
This process is called radioactive decay. Consider a particular kind or isotope of atom that is unstable. Copyright 1995 by PWS Publishing Company, a division of International Thomson Publishing Inc.
