Question

Part 1: 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.

Part 2: View and comment on the work of at least 2 other students. Try to choose students whose work is based on different real-world examples than the ones you chose.

Answer 1

exponential growth: dandelions

decay: garbage

Answer 2

can you explane it ms. sue

Answer 3

exponential growth means that the rate of increase is proportional to the present amount. As more and more dandelions spread their seeds, the patch grows faster and faster, since each new flower contributes more new flowers to the population.

Same for decay. As the amount decaying shrinks, there is less and less to contribute to the disintegration. Radioactivity is a common instance, but maybe not quite so available in everyday life.

Answer 4

Thx Steve

Answer 5

You could switch dandelions out for any other type of plant or flower that produces a lot.

Answer 10

idek i just wanna be apart of this arguent lol

Answer 11

I believe it's also applicable to loans

Answer 13

Exponential*

Answer 14

this was SO much help

Answer 16

ate that

Answer 17

dude. What happened here?

Can you guys not get so mad for no reason? Just shut up.

Answer 19

1. We are more aware of environmental issues today. The longer certain food sits out in the sun at a picnic, the more bacteria grows on it. It might still look good, but with higher temperatures the bacteria grows more quickly. 2. The more someone with a bad cold sneezes and touches things, the faster it will spread to another person. 1. When paper is left out in the elements (bad weather) it will deteriorate (decay) and dissolve until it is gone. 2. When a apple grows on it's tree, then falls and slowly rots away. Decay
