Let the length of latus rectum of an ellipse with its major axis along x-axis and center at the origin,be 8. If the distance between the foci of this ellipse is equal to the length of the minor axis,then which of the following points lies on it: (a) (4sqrt(2),2sqrt(2)) (b) (4sqrt(3),2sqrt(2)) (c) (4sqrt(3),2sqrt(3))( d) (4sqrt(2),2sqrt(3))

Check which of the following are solutions of the equation x-2y=4 and which are not ? (sqrt(2),4sqrt(2)) .

Rationalise the denominator of the following : (a)(2)/(3sqrt(3))" "(b)(sqrt(40))/(sqrt(3))(c )" "(3+sqrt(2))/(4sqrt(2))" "(d)(16)/(sqrt(41)-5)" "(e)(2+sqrt(3))/(2-sqrt(3))

4. . simplify (4+sqrt(2))(4-sqrt(2))

Which of the following are G.P.? If they are in G.p . Write next three terms ? 1/(sqrt(2)),-2,4sqrt(2)

Check which of the following are solution of the equation x-2y=4 and which are not : (sqrt(2),4sqrt2)

If p and q are positive real numbers such that p^2+""q^2=""1 , then the maximum value of (p""+""q) is (1) 2 (2) 1/2 (3) 1/(sqrt(2)) (4) sqrt(2)

If p and q are positive real numbers such that p^2+""q^2=""1 , then the maximum value of (p""+""q) is (1) 2 (2) 1/2 (3) 1/(sqrt(2)) (4) sqrt(2)
