Use Newton’s Law of Cooling, T = C + (T0 - C)ekt, to solve:You are served a cup of coffee that has a temperature of 185°F. The room temperature is 65°F. After 2 minutes, the temperature of the coffee is 155°F. a. Write a model for the temperature of the coffee, T, after t minutes. b. When will the temperature of the coffee be 105°F?

A new building that costs $1,000,000 has a useful life of 100 years and a scrap value of $500,000. Using straight-line depreciation, find the equation for the value V in terms of t, where t is in years. Find the value after 1 year, after 2 years, and after 90 years.V(t) =        value after 1 year   $  value after 2 years   $  value after 90 years   $
