Using the exponential decay formula: A = P (1 - r) t. A = 20000 (1 - 0.08) 5 = 13181.63. Therefore, the value of the car after 5 years = $13,181.63. Example 2: Jane bought a new house for $350,000. The value of the house decreases exponentially (depreciates) at a rate of 5% per year.
WebJul 12, 2024 · The half-lives of radioactive isotopes can be used to date objects. The half-life of a reaction is the time required for the reactant concentration to decrease to one-half its initial value. The half-life of a first-order reaction is a constant that is related to the rate constant for the reaction: t 1/2 = 0.693/ k.
