(B) A whole number
(c) A real number
(D) A natural number
ans:-(c)real number
2. 1. Which one is not a polynomial
(a) 4x2 + 2x – 1
(b) y+3/y
(c) x3 – 1
(d) y2 + 5y + 1
ans:-b
3. Which point lies in the IV quadrant :
(A)(-2,-5)
(B) (3. -4)
(C) (-2, 6)
(D) (0, 4)
ans:- c
4. If p(x) = 5x - 4x² + 3. then p(-1) is
(A) 2
(B) -2
(C)6
(D) -6
5. The equation of y-axis is
(A) x = 0 (B) y = 0
(C) x=y (D) x + y = 0
ans:-The equation of y-axis is x = 0, since, y-axis is a parallel to itself at a distance 0 from it. Let P (x, y) be any point on the y-axis.
6. In AABC, AB - AC and 2 B = 50°, then ZC is equal to
(A)402
