Question: An object at a temperature of 160°C was removed from a furnace and placed in a room at 20°C. The temperature T of the object

An object at a temperature of 160°C was removed from a furnace and placed in a room at 20°C. The temperature T of the object was measured each hour h and recorded in the table. A model for the data is T = 20 + 140e - 0.68h.

Hour, h Temperature, T DATA 160° 90° 56° 38° 3 4 29° 5 24° Spreadshoet at LarsonPrec alculus.com

(a) The figure below shows the graph of the model. Use the graph to identify the horizontal asymptote of the model and interpret the asymptote in the context of the problem

(b) Use the model to approximate the time it took for the object to reach a temperature of 100°C.
