Let's explore exponential growth and decay, the worksheets available for learning these concepts, and how they help in mastering the material.
Understanding Exponential Growth 📈
What is Exponential Growth?
Exponential growth occurs when a quantity increases at a rate proportional to its current value. This means that the larger the quantity, the faster it grows. It's commonly represented by the formula:
[ P(t) = P_0 \cdot e^{rt} ]
- P(t): the amount at time ( t )
- P_0: the initial amount
- e: the base of the natural logarithm (approximately equal to 2.718)
- r: the growth rate
- t: time
Real-World Applications
- Population Growth: Many populations grow exponentially under ideal conditions.
- Investment Growth: Compounded interest on investments often follows exponential growth patterns.
Understanding Exponential Decay 📉
What is Exponential Decay?
Conversely, exponential decay describes a process where a quantity decreases at a rate proportional to its current value. The formula for exponential decay is similar to that of growth:
[ N(t) = N_0 \cdot e^{-kt} ]
- N(t): the amount at time ( t )
- N_0: the initial amount
- k: the decay constant (rate of decay)
- t: time
Real-World Applications
- Radioactive Decay: The amount of radioactive substance decreases exponentially over time.
- Depreciation of Assets: The value of physical assets often declines exponentially.
