2 When an object with an initial temperature Tis placed in a substance that has a temperatures, according to Newton's law of cooling, in t minutes it will reach a temperature Tt using the formula TL=+(T-S) e (dt), where k is a constant value that depends on properties of the object. For an initial temperature of 100 and * =0.6, graphically display the resulting temperatures from 1 to 10 minutes for two different surrounding temperatures: 50 and 20. Use the plot function to plot two different lines for these surrounding temperatures
