MHB Conversion KWH of energy per day to Joules in a year

AI Thread Summary
An appliance that consumes 6.65 kWh per day has an average power consumption of approximately 277 watts. To convert this daily energy consumption into joules for a year, the total energy consumed is calculated by multiplying the daily usage by the number of days in a year, resulting in 2,426,400 kJ. The conversion factor from kilowatt-hours to joules is essential for this calculation, where 1 kWh equals 3.6 million joules. The formula P = W/t is used to relate power, work, and time, confirming the average power consumption over a year. Understanding these conversions is crucial for energy management and appliance efficiency.

What is the average power consumption in watts of an appliance that uses 6.65 kW*h of per day?

6650/24=277 W

b) How many joules of energy does this appliance consume in a year?

What is the conversion factors for b)?

P = W/t. (P = power, W = work = energy output more or less, t = time.) You've got P from part a and now t = 1 year.

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...

Thread 'Unit Circle Double Angle Derivations'

Thread 'Unit Circle Double Angle Derivations'

Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...

Thread 'Imaginary Pythagoras'

Thread 'Imaginary Pythagoras'

I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
