Water Temperature – Time vs. Hours
The following table shows the time, in hours, before the body of a scuba diver, wearing a 5-millimeter-thick wet suit, reaches hypothermia (95oF) for various water temperatures.
The following function, which is an example of an exponential function, closely models the data in the table:
Water Temperature, oF
Time, hours
36 1.5
41 4.8
46 2.6
50 3.1
55 4.9
( ) 0.1509(1.0639)FT F
Assignment: Use your calculator to find the exponential regression equation.

Speed of Technology
• In 1965, Gordon Moore, one of the cofounders of Intel Corporation, observed that the maximum number of transistors that could be placed on a microprocessor seemed to be doubling every 18 to 24 months.

• When you buy a new computer or smartphone, it will be out-dated within 6 months.• Most recent data points indicate a doubling processing time as short as 12 months.• This would mean that there will be a thousand-fold increase in computational power
in 10 years. • Moore's Law is what chip manufacturers rely on when they decide what sort of chip
to develop in order to remain competitive.
