  6. Finding Domain

  7. Regression Using the charts below, determine whether each set of data is best represented by a linear, logarithmic, exponential or power regression equation. Support your answer with a sketch and mathematical data.

  8. Order of Magnitude • Order of magnitude: the common logarithm of a positive quantity • A kilometer is _______ orders of magnitude longer than a meter. • A dollar is _______ orders of magnitude greater than a penny. • A horse weighing 400 kg. is ______ orders of magnitude heavier than a mouse weighing 40 g. • NYC with 7 million people is ______ orders of magnitude bigger than Earmuff Junction with a population of 7.

  9. Newton’s Law Newton’s Law of Cooling: …where t = Tm = T0 = k = Example: A cake is removed from an oven at 350° and cools to 120° F after 20 minutes in a room at 65°F. How long will the cake take to cool to 90°F?

  10. More Applications How many times more severe was the 1995 Kobe, Japan earthquake (R = 7.2) than the 1994 Los Angeles earthquake (R = 6.6)?
