The value of `x^0` is:
a) 0
b) 2
c) 1
d) 3

If x-a is a factor of x^3-3x^2a+2a^2x+b , then the value of b is (a) 0 (b) 2 (c) 1 (d) 3

If x lies in the interval [0,\ 1] , then the least value of x^2+x+1 is (a) 3 (b) 3//4 (c) 1 (d) none of these

In Figure, if A B||C D , then the value of x is (a) 20^0 (b) 30^0 (c) 45^0 (d) 60^0

Let A B C be a triangle. Let A be the point (1,2),y=x be the perpendicular bisector of A B , and x-2y+1=0 be the angle bisector of /_C . If the equation of B C is given by a x+b y-5=0 , then the value of a+b is (a) 1 (b) 2 (c) 3 (d) 4

If the focus of the parabola x^2-k y+3=0 is (0,2), then a values of k is (are) (a) 4 (b) 6 (c) 3 (d) 2

The value of 3/(25) is (a)1.2 (b) 0.12 (c) 0.012 (d) None of these

In Figure, if l_1||l_2, what is the value of x ? (a) 90^0 (b) 85^0 (c) 75^0 (d) 70^0

If x=(7+5sqrt(2))^(1/3) -1/((7+5sqrt(2))^(1/3) , then the value of x^3+3x-14 is equal to 1 (b) 0 (c) 2 (d) 4

If the focus of the parabola x^2-k y+3=0 is (0,2), then a values of k is (are) 4 (b) 6 (c) 3 (d) 2
