# Thread: measure slope of a tangent

1. ## measure slope of a tangent

A roast 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 one hour.

how do you find °F/min?
i got 125 from the point on the graph but it was wrong

you're suposed to estimate the slope of the red line tangent to point P, not the value of T.

rise/run ... remember?

3. how do you find this tho?
