Question

How are exponential growth and decay present in the real world? Give at least 2 examples for exponential growth and 2 examples of exponential decay.

My Answer: I have only been able to think of one example of exponential growth which is hair growth. From 2012, the length of hair someone's hair grows 50% each year. In 2012, the person's hair length was 12 inches.

I'm not sure what else I can do for the second one.Also, I'm not sure what I can come up with for exponential decay. Can someone please help me?

Thank you, in advance! :)

Answer 1

Hair does not grow that way. It grows at a fixed rate, it doesn't grow any faster for folks with long hair.

growth: Interest on money in a bank
bacteria
chicks

decay:
radioactivity
temperature of hot water in a cup.
