Wind power produces a bit more 2.5 watts per square meter.

And here's a solar park in Vermont, with real data, delivering 4.2 watts per square meter.

The conclusion drag is proportional to area.

Being generous to concentrating solar power,

Remember those increased summer time daylight hours?

Good thing they had that number there so I could try it out.

We learned in the imaginary numbers video, that hopefully you've watched, that every now and then in certain equations you end up with a square root of a negative number.

So, this facility delivers 14 watts per square meter this one 10 watts per square meter and this one in Spain, 5 watts per square meter.

You can always every perfect square has a positive or a negative root.

And so the first house has size two hundred four square feet, has three bedrooms second house has sixteen hundred square feet, has three bedrooms and so on.

When we're taking the square root, it's not just the positive square root.

That's the UK.

1,344 plus 25.

You have to distribute the b squared.

We can get another square furgle on there and we can get a third square furgle on there!

And yes, it's US 30 per square foot.

And then you get y is equal to and I'm doing this on purpose the plus or minus square root, because it can be the plus or minus square root.

Let me ask you the same question.

If some of you play chess, you'll know that 64 is a square number, and that's why chessboards, eight by eight, have 64 squares.

And two, there are better ways to do this.

I just the square root of it, and we have to get the square root of the denominator too.

Square Root

Square root

Sum of all data items squared

The area is equal to (let me write this down)... We have (let me write it down)... We have

So it's pretty clear when you calculate the area that Apple Lane, you are getting more square meters than you would get at Fibonacci Drive.

Plus the difference in the y's squared y minus b squared.

Take the imaginary part squared so let me write this.

So x is equal to 2 is 4.

You could rename it with anything really, is equal to the square root of x minus 1.

Horizontally

Square Root Scale

0.0 sq km

150 square feet.

So let's see, so we get x.

The answer is 80 per square foot, and we get this by just dividing 112,000 by 1400.

That's the other way to think about this.

We want the right side to just be x minus 1.

We can solve the mystery simply by looking at the actual difference between these two values.

Plus 64 pi, let me scroll over to the right a little bit. Plus 64 pi cm squared.

So what do we do now?

In our case, the correct range for x is 0 to maxint.
