If the area of the region \(x, y) : 1 - 2x y 4 - x2, x 0, y 0\ is , , N, ( , ) = 1, then the value of ( + ) is:

  1. 73
  2. 85
  3. 67
  4. 91

Answer

(1) 73

Solution

Upper boundary y = 4 - x2 meets y = 0 at x = 2 (for x 0)

1 - 2x 4 - x2 ⇔ (x - 3)(x + 1) 0, true for all x [0, 2]

Lower boundary: y = 1 - 2x for 0 x 12 and y = 0 for 12 x 2

Area = 02 (4 - x2) dx - 01/2 (1 - 2x) dx

= (8 - 83 ) - ( 12 - 14 )

= 163 - 14 = 6112

= 61, = 12

+ = 73
