The following data was collected to determine the cooling rate of a new insulation material. the mathematical equation describing the cooling rate for each material is of the exponential form t(t) = tinitiale at t(t) is the temperature of the material at timet tinitial is the temperature at t=0 mins a is the thermal capacity of the material 1. report the equation and correlation coefficient of the best fit straight line for the material. report all values to o significant figures. 2. determine the initial temperature (tinitial) and the thermal capacity (a) of the material. report all values to o significant figures. 3. what is the temperature of the material att 65s. report values to 6 significant figures. 4. according the the given table, the temperature of the material att part 2. should the values be the same? explain. mins (tina) is equal to 326 °c. compare this number to your answer from lo tmins) tc) 326.00 253.00 199.00 157.00 124.00 100.00 80.00 65.00 53.00 44.00 50 36.00

Atrain traveled for 1.5 hours to the first station, stopped for 30 minutes, then traveled for 4 hours to the final station where it stopped for 1 hour. the total distance traveled is a function of time. which graph most accurately represents this scenario? a graph is shown with the x-axis labeled time (in hours) and the y-axis labeled total distance (in miles). the line begins at the origin and moves upward for 1.5 hours. the line then continues upward at a slow rate until 2 hours. from 2 to 6 hours, the line continues quickly upward. from 6 to 7 hours, it moves downward until it touches the x-axis a graph is shown with the axis labeled time (in hours) and the y axis labeled total distance (in miles). a line is shown beginning at the origin. the line moves upward until 1.5 hours, then is a horizontal line until 2 hours. the line moves quickly upward again until 6 hours, and then is horizontal until 7 hours a graph is shown with the axis labeled time (in hours) and the y-axis labeled total distance (in miles). the line begins at the y-axis where y equals 125. it is horizontal until 1.5 hours, then moves downward until 2 hours where it touches the x-axis. the line moves upward until 6 hours and then moves downward until 7 hours where it touches the x-axis a graph is shown with the axis labeled time (in hours) and the y-axis labeled total distance (in miles). the line begins at y equals 125 and is horizontal for 1.5 hours. the line moves downward until 2 hours, then back up until 5.5 hours. the line is horizontal from 5.5 to 7 hours
