So now that we have computed the decay factor we get that the exponential decay formula is. So generally speaking half life has all of the properties of exponential decay. When given a percentage of growth or decay determined the growthdecay factor by adding or subtracting the.
Because this is an exponential decay factor this article focuses on percent decrease.
PERT formula is an approximation of the Beta Distribution equation. It calculates a weighted average instead of simple average. Finding the rate or time in a word problem on continuous growth or decay. Often to measure something involving an exponential decay we wait until the decay is over and only once everything is steady we take our measurement.
