`x lt 8 - 4y`

IF 4lt x lt 8 then the value of - 7x^2+8x -9 is

If 4 lt x lt 8 then the value of 12x -x^(2) - 32 is

If 4 lt x lt 8 then the value of 12x -x^(2) - 32 is

The number of terms in expansion of (4y + x)^8 - (4y - x)^8

If 0 lt x lt 1 and y = x - x^(2) + x^(3) - x^(4) + ....... infty then y + y^(2) + y^(3) + ......... infty is equal to

The function f(x) = sin^(4)x + cos^(4) x increases if a) 0 lt x lt pi//8 b) pi//4 lt x lt 3 pi//8 c) 3 pi//8 lt x lt 5pi//8 d) 5 pi//8 lt x lt 3 pi//4

The circle x^2 +y^2=4x+8y+ 5 intersects the line 3x-4y= m at two distinct points, if (a)-85 lt m lt-35 (c) 15 lt m lt 65 (b)-35 lt m lt 15 (d) 35 lt m lt 85

Let U = { x|x = 2^n . N in W , n lt 8} be the universal set . A = {y|y= 4^2, n in W , n lt 4} , B = {z|z = 8^n , n in W , n lt 2 } . Then find : (A uu B)
