The scatterplot below shows the temperatures of a cup of hot cocoa after it is poured into a serving cup. The hot cocoa starts at approximately 180º F, but the temperature decreases over time. A scatter plot showing the temperature of hot cocoa decreasing as time (mins) go by. It is an exponential decreasing function with the equation 171.46e^-0.012x Use the graph and trend line equation, y=171.46e−0.012x , to estimate the temperature of the hot cocoa after 45 minutes. (Round your answer to the nearest whole degree) Number degrees Fahrenheit
