When an object is removed from a furnace and placed in an environment with a constant temperature of 23°C, its core temperature is 720°C. The temperature of the object t hours after it has been removed from the furnace is described by the function

F (t) = 23 + 697e ^−0.261t

Based on this function, how warm will the object be after five hours?
