Use formula A²+B²=C²
120²+62²=C²
14,400+3,844=C²
14,400+3,844=18,244
√18,244=135.07035...
135.07035...≈135.1
First you need to put it into y=mx+b format and which is 1/2x + 2 =y. The y intercept should be b in the equation y=mx +b so y=2. The x-intercept should be when y=0 and x equals a number which is x=-4. X-intercept=-4 and y-intercept=2.
The object is to get everything except for "h" on one side of the equation.
The equation says that everything on the right side is being multiplied by 1/2.
What do we have to multiply times 1/2 to get 1? The answer is 2.
So multiply both sides by 2 to get rid of the fraction.
2A = (a+b)h
Now we are multiplying h times (a+b) so to get rid of (a+b) we have to divide both sides by that term.
(a+b)/(a+b) is 1
So you are left with: 2A/(a+b) = h
Done!
The answer would be (-5,9)
The formula of a 270° rotation about the origin is (x,y) <span>→ (-y,x).</span>
I think the 3 is an exponent so we can write the expression as
18 * 4y^3
= 72y^3
