A solid object with an initial temperature of 75 degrees Fahrenheit is dropped into a lake with a temperature of 33 degrees Fahrenheit. The function f(t)=Ce(−kt)+33 represents the situation, where t is time in minutes, C is a constant, and k is a constant. After 2 minutes the object has a temperature of 55 degrees. What will be the temperature of the object, in degrees Fahrenheit, after 4 minutes?
