Answer:
360°
75° + 15t
Step-by-step explanation:
Given that the initial temperature of the oven is 75° and the temperature will increase at a rate of 15° per minute, it means that the temperature T after x minutes will be given as
T = 75 + 15x
Hence after 19 minutes, the temperature will be
= 75 + 15(19)
= 75 + 285
= 360°
After t minutes, the temperature will be
= 75° + 15t
