Steps for Finding General Solutions to Differential Equations Involving Exponential Decay Step 1: Identify the proportionality constant in the given differential equation. This is the number multiplied by y. Step 2: Compose the equation y=Cekt by substituting the proportionality cons...
Solution: Because carbon-14 decays due to radioactivity, we can use the exponential decay equation. N(t) = A e(-kt). From Problem 1, the decay constant for carbon-14 is 1.21 * 10(-4) /years. Additionally, if the original population of carbon-14 is A, then N(t) = 0.65A. 0.65...
Exponential decay: Exponential decay is a process in which a material's mass decreases over a long period of time. For example, radioactive materials (called isotopes) decay due to emission of radioactive alpha or beta...
