Aroast turkey is taken from an oven when its temperature has reached 185°f and is placed on a table in a room where the temperature is 75°f.
the graph shows how the temperature of the turkey decreases and eventually approaches room temperature.
by measuring the slope of the tangent, estimate the rate of change of the temperature after an hour.

It is very important to look at the graph very minutely. It can be seen that at 30 minutes the slope is a little more than negative 50 and at 90 minutes it is a little less than negative 50. From this fact, it can be deduced that the estimated rate of change of the temperature after an hour would be -50/60. I hope that the answer has come to your desired help.
