Examples of exponential decay in real life
Radioactive decay of the isotopes of radioactive elements is a prominent example of exponential decay in real life. Let us assume, if the substance has a half-life of one week, i.e., if the radioactivity of a particular substance reduces to half of its original value on the last day of every passing week, it is said to be … See more The reselling cost of a car or any other product deteriorates with every passing year. During the first year, the original cost of the product gets depreciated by a constant percentage and the depreciated new cost of the car is … See more The concept of exponential decay is used to keep a track record of the population of the species that are on the verge of extinction. For instance, if a certain species of birds are … See more Suppose a child is given a bag of candy. He/she wishes to eat the half of candies present in the bag every day. In such a case, exponential decay can be observed easily. For instance, … See more When a person who is suffering from a bacterial or viral disease visits a doctor to receive treatment, the doctor tends to provide him with certain antibiotic drugs and medicines. … See more WebCompound internet, decpreciation, growth of virus, spoiling of perishable foods, are some of the real life examples which need to be calculated using a math formula. The exponential growth and decay gives the required needed calculations using the formulas f (x) = a (1 + r) t, and f (x) = a (1 - r) t.
