For example, some inexpensive mowers are designed to have a service life of 200 or fewer hours while pricier mowers typically are designed to last 500 or more hours. Therefore, a lawnmowerâs life expectancy can be based on how often and how long it is used.
exponential growth. Increase in number or size, at a constantly growing rate. It is one possible result of a reinforcing feedback loop that makes a population or system grow (escalate) by increasingly higher amounts. Compound interest is an example of exponential growth. Use 'exponential growth' in a Sentence.
Exponential growth (including exponential decay) occurs when the growth rate of a mathematical function is proportional to the function's current value. In the case of a discr â¦ ete domain of definition with equal intervals it is also called geometric growth or geometric decay (the function values form a geometric progression). Exponential growth is said to follow an exponential law; the simple-exponential growth model is known as the Malthusian growth model. For any exponentially growing quantity, the larger the quantity gets, the faster it grows. An alternative saying is 'The rate of growth is directly proportional to the present size'.
