this means this is equivalent to the square root of 4.
So you actually can't factor this anymore. So a is just going to be equal to the square root of 115.
So we learned just now that A is equal to B is equal to the square root of 2 over 2 times C.
This is equal to the square root, open parentheses, of this over here is c plus a squared minus b squared, over 4.
Therefor the minimum velocity V required to keep the creature airborn is proportional to the square root of the scale of the creature; i.e.
Let me rewrite it over here. c squared is equal to 130, or we could say that c is equal to the square root of 130.
Now lets try it, when x is equal to 2. F of 2 is going to be equal to the square root of 0.5 times 2 minus 1.
Or 2B squared is equal to C squared. Or B squared is equal to C squared over 2. Or B is equal to the square root of C squared over 2.
could rename it with anything really, is equal to the square root of x minus 1.
And then if we are kind of extending the definition of square roots to negative numbers, then we can go the other way around and we could say threei is equal to the square root of negative nine.
So this is a 45-45-90 triangle, and we know one of the sides-- this side could be A or B-- we know that 8 is equal to the square root of 2 over 2 times C.
So if we take the square root of both sides of this equation we get x plus b/2a is equal to the square root of this-- let's take the square root of the numerator and the demoninator.
So we could even rewrite this as f inverse of y. That's what x is, is equal to the square root of y minus 1 minus 2,
And then the area by Heron's Formula is going to be equal to the square root of S-- 18-- times S minus a-- S minus 9. 18 minus 9, times 18 minus 11, times 18 minus 16.
We just solved for that. So h is going to be equal to the square root of all this business in there-- I will switch the colors-- of a squared minus c squared plus a squared minus b squared.
So this whole thing is going to be equal to the square root of x plus y, or in this case it's ca over 2 plus the y, which is c squared plus a squared minus b squared over 4.
So this is going to be equal to the square root of 2 times 2-- I will put it in parentheses-- 2 times 2, times 2 times 2, times 2 times 2, times 5 times 5, times 5 times 5.
