What are two variables that have a linear or nonlinear relationship that happen in real life?

Question

I need this to be realllllllllllllllllllllllllllllllllly creative, please. :) It also has to be a real life relationship. Please, help!

I am focused more on just a creative relationship than a linear one, for example, how long acountry has been independant, and how many wars it's been in, or the length of people's fingernails and typing speed, but really interesting. I don't need an equation, but thank you!

Answer 1

A linear example:

The demand for some types of products declines linearly with price. The variables are Price on the x-axis and Quantity demaded on the y-axis. The line has a negative slope

Another linear example:

The speed of your car is approximately a linear function of the force you exert on the pedal. If you put pedal force on the x-axis and speed on the y-axis, the line will have a positive slope.

This is a great question. Astrological compatibility is a touchy subject for me. Just because astrology might indicate that two people would be perfect for each other doesn't mean they will stay together or even have a good relationship. Since the position of the Sun, Moon, planets, etc. are only influences on the personality and since upbringing, free will, and environment are the other factors in determining who you are then any compatibility reading is open to have anything happen. That is why I always say no astrological match is impossible, just because it indicates that a couple is incompatible doesn't mean they couldn't be happily married until the day they die. So I generally stay away from those questions unless they are specific about what they want to know and unless they have enough info. If all they know are Sun signs I find it quite useless because Sun signs mean very little in relationships as a whole. I stick to just talking about how their Moon, Venus, and Mercury signs work with each other and focus on trying to show them where they may be alike and different in those areas. I don't do synastry or Davison charts or any of the others. That is not my specialty and I think this area is where people tend to rely too heavily on astrology as the be all end all and astrology should never be thought if in that way. Skeptics love to get into this area in a way to "disprove" astrology and bad questions add fuel to the fire cause they get answers sometimes that are not relevant and give those haters something to use, IMO.

New cars prices and money spent has a linear relationship.

If one ferrari cost 200 grand, 2 would cost $400,000.

So you can only buy as many as you have cash.
N= number of ferraris purchased
M= money spent
M = 200,000 N

The number of rabbits someones is a nonlinear relationship as they multiply exponentially.
2 rabbits may produce 4 rabbits.
T = Total rabbits
R = Initial number of rabbits

so T = R^2

Easy, just use the gravitational relationship that the force of attraction between two bodies is inversely proportional to the square of the distance r between them:
Force = C/r^2, where C is a constant
