Understanding the Formula: Let N(d) = k × (1/2)^(d/20) In mathematical modeling, exponential decay functions are widely used to describe processes that diminish over time, distance, or another variable. One such formula is Let N(d) = k × (1/2)^(d/20), where N(d) represents a quantity at distance d, k is the initial value, and d is the independent variable—often distance, time, or intensity. This clean, yield-rich function captures how a value halves every 20 units, making it invaluable in fields like physics, signal processing, epidemiology, and environmental science. --- ### Breaking Down the Formula
