If we take the natural log of both sides of this equation, the result is the following: In A--At+In A- A- Age-At Notice that our equation now has the form of an equation of a line, y = mz+b, with y = In A and a slope of -A. This line is plotted in Figure (b). . A sample of radioactive material is obtained from a very old rock The activity of the rock over a period of time is monitored, and In A is plotted as a function of t, such as in Figure (b). The slope of the line has a value of -1.6x10* y t (a) with Expert TANT of spying the formations to say solutions & What is the half-life of this material in units of years? TUA y slope = -A (b) Grade Summary Deductions Potential 100%
