10. A sample of metal is heated to 698°C and then allowed to cool. The temperature of the metal over time is given by the formula n= 698– 21 -0.51, where t is the time in seconds after the start of the cooling process, and n is the temperature of the sample in degrees Celsius. After how many seconds will the temperature of the sample be 500°C? a) 16 b) 18 c)20 d) 22 e) 24 f) 26
