Exponential decay word problems worksheet

What is Exponential Decay? Where, y is defined as the final amount, a represents the original amount, b is the decay factor and, x represents the amount of passed time. Exponential decay differs from linear decay in terms of decay factor. In the linear function, the original number is decreased by the same amount every time. However, in exponential decay, the decrease in the original amount changes over time. That means the decay factor depends on a certain percentage of the original amount. Let's properly define and understand each of its elements: Decay factor b - Decay factor is defined as the percentage decrease of the original amount. Original Amount a - The original amount is the amount before the occurrence of decay. For example, the original amount is the number of cherries a bakery buys, and the exponential factor is the percentage of used apples every hour to bake cherry pies. The exponential decay x - The 'x' written as the exponent represents the exponential decay. Exponential decay is always expressed in time. It shows the frequency of the decay and is usually stated in seconds, minutes, hours, days, or years.

Exponential decay word problems worksheet

Exponential growth is a process that increases quantity over time. Linear functions change at a constant time per unit interval. Exponential functions can also be used to model populations that shrink from deadly diseases or maybe chemical compounds that break down over time. These models exhibit exponential decay and not exponential growth.
