#### Theme: Half life dating equation solver

greenhouse gas calculator / carbon footprint calculator Most people find the subject of radiometric dating too technical to understand. Until recent years
I'm assuming that you have some experience at solving linear equations, so I .. time and half-life of exponential growth and decay Next: Developing an initial 0.013t Solve each application problem. 82. 85. 91. 92. A A0e Half-life To the nearest thousand years, find the half-life of plutonium-239, given that it decays according to the formula . Tritium decay The half-life of tritium is 12.4 years.
A radioactive substance is often described in terms of its half-life, which is the A in the formula for exponential decay to be equal to (1/2)A0, and then solve for t.
