Quick Recall Flashcards

What is the formula for exponential decay?
N = N₀ × (1 - r)ⁿ Where: N = final amount N₀ = initial amount r = decay rate (as decimal) n = number of time periods
What is the formula for half-life decay?
N = N₀ × (0.5)ⁿ Where: N = remaining amount N₀ = initial amount n = number of half-life periods
