WebJul 12, 2024 · To find how old the bone is, we first will need to find an equation for the decay of the carbon-14. We could either use a continuous or annual decay formula, but opt to use the continuous decay formula since it is more common in scientific texts. The half life tells us that after 5730 years, half the original substance remains. Solving for the ... WebAug 27, 2024 · Radioactive Decay. Experimental evidence shows that radioactive material decays at a rate proportional to the mass of the material present. According to this model the mass \(Q(t)\) of a radioactive material present at time \(t\) satisfies Equation \ref{eq:4.1.1}, where \(a\) is a negative constant whose value for any given material must … WebOnline math solver with free step by step solutions to algebra, calculus, and other math problems.
