After heating up in a teapot, a cup of hot water is poured at a temperature of 20 8 ∘ 208 ∘ F. The cup sits to cool in a room at a temperature of 6 8 ∘ 68 ∘ F. Newton's Law of Cooling explains that the temperature of the cup of water will decrease proportionally to the difference between the temperature of the water and the temperature of the room, as given by the formula below: T = T a + ( T 0 βˆ’ T a ) e βˆ’ k t T=T a ​ +(T 0 ​ βˆ’T a ​ )e βˆ’kt T a = T a ​ = the temperature surrounding the object T 0 = T 0 ​ = the initial temperature of the object t = t= the time in minutes T = T= the temperature of the object after t t minutes k = k= decay constant The cup of water reaches the temperature of 18 5 ∘ 185 ∘ F after 3 minutes. Using this information, find the value of k k, to the nearest thousandth. Use the resulting equation to determine the Fahrenheit temperature of the cup of water, to the nearest degree, after 4 minutes.
