An iron bar with an initial temperature of 10°C is heated such that its temperature increases at a rate of 4°C/min. The temperature, C, in degrees Celsius, at any time, t, in minutes, after heat is applied is given by the function c= 10 + 4t. The equation F= 1.8c + 32 is used to convert from C degrees Celsius to F degrees Fahrenheit. Determine the instantaneous rate of change of the temperature, in degrees Fahrenheit, of the bar with respect to time at 4 mins
