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.

Answer 1

Someone help?

Answer 2

example interest if you get for example 10% an year that is in the end of the year you have 1,2*x where x is your initial money. so after n years you will have 1,2^n*x and 1,2^n is obviously an exponential function which grows

Answer 3

nuclear decay

Answer 4

exponential growth: compound interest, growth in size of a bacterial colony

Answer 5

Hey, ktklown, when you're done with this question, can you come back to mine? I'm still lost and have no idea what to do...

Answer 6

Was the first example correct as well? as @mivanov gave?

Answer 7

that's compound interest

Answer 8

what's another example for decay? I don't understand it completely.

Answer 9

maybe,... i don't know, the charge in a capacitor vs time?

Answer 10

i think that's exponential decay

Answer 11

or the number of teams competing in a tournament as they get eliminated, that's exponential decay with the round number

Answer 12

So nuclear decay is exponential decay?

Answer 13

yes

Answer 14

nuclear bombs on the other hand are chain reactions with are exponential growth
