Step-by-step explanation:
dy/dx
= d/dx [x / (1 - x²)]
= [(1 - x²)(1) - (x)(-2x)] / (1 - x²)²
= (1 + x²) / (1 - x²)².
When dy/dx = 1, (1 + x²) / (1 - x²)² = 1.
=> 1 + x² = 1 - x² 
=> 2x² = 0, x = 0.
Also when x = 0, y = (0) / [1 - (0)²] = 0.
Hence the coodinates is (0, 0).

#5,
it says that the angle on top is 221, so you subtract that from 360,
360-221= the rest..... 139
 Now in that 139, you can see that there is a triangle with a right angle. so you can subtract 90 degrees from 139
139-90= 49
49 is the number you use to solve the rest.
3x + 4x = 7x
so 7x = 49
and then you divide 7 from both sides to isolate x, and you get your answer

Answer:
126.5
Step-by-step explanation:
Divide the shape into two, so you have a triangle and a rectangle. 
Area of Rectangle:
A = bh
   = (11)(8)
   = 88
Area of Triangle:
A = 1/2bh
    = 1/2(11)(7)
    = 38.5
Add the two areas and the answer is 126.5
