- Half-Life The half-life of plutonium-241 is approximately 13 years. How much of a sample weighing 4 g will remain after 100 years? How much time is necessary for a sample weighing 4 g to decay to 0.1 g?arrow_forwardTracer Dye The amount of a tracer dye injected into the blood stream decrease exponentially, with a decay constant of 3 per minute. If 6 cc are present initially, how many cubic centimeters are present after 10 minutes? Here k will be negative.arrow_forwardIn the exponential growth or decay function y=y0ekt, what does y0 represent? What does k represent?arrow_forward
