I am confused about the energy output a windmill has. How much overall watts per day can you receive from a 3000 watt waindmill? From what I understand, a windmill will only produce lets say 3000 watts when wind speed is 28 mph. If that is the case, how many watts will it produce when the wind speed is 7 mph which is the average wind speed in most places? So how many watts per hour per day would you receive from this? Considering a 3000 watt wind mill costs $6,000 would it really only produce 1kW every hour on average cause that isnt much? And if that is correct or close to it, if 1kWh is produced 24 hours a day, and it is used for 12 hours a day, will the other 12kW be stored in a battery for later use? Thanks a lot for your answers!

How do you find the asymptotes of an equation? What is the difference between the long division method and the dominant rule method of finding asymptote?

the dominant rule method is something like (2x - 4) / (x^2 - 4) becomes 2x / x^2 when x tends to infinity but i don't know how it works?

Please try to show an example and use both was to solve.
