Forge welding is a process in which two pieces of steel are joined together by heating the pieces of steel and hammering them together. A welder takes a piece of steel from a forge at 1600 degree F and places it on an anvil where the outdoor temperature is 70 degree F. The temperature of the steel T (in degree F) can be modeled by T = 70 + 1550e^-0.05t, where t is the time in minutes after the steel is removed from the forge. How long will it take for the steel to reach a temperature of 105 degree F so that it can be handled without heat protection? Round to the nearest minute. It will take minutes for the steel to reach a temperature of 105 degree F. Show transcribed image text
