The direction ratios of the line 2y+z-5=0=x-3y-6 are proportional to 3,\ 1,\ -2 b. 2,\ -4,\ 1 c. 3/(sqrt(14)),1/(sqrt(14)),(-2)/(sqrt(14)) d. 2/(sqrt(41)),(-4)/(sqrt(41)),1/(sqrt(41))

If x+y=2 is a tangent to the ellipse foci are (2,3)&(3,5) is A) length of minor axis is 6 B) length of minor axis is 3 C) length of major axis is (sqrt(41))/(2) D) eccentricity of ellipse is (sqrt(5))/(sqrt(41))

If any point on a hyperbola has the coordinates (5tan phi,4sec phi) then the eccentricity of the hyperbola is: (A)(5)/(4) (B) (sqrt(41))/(5) (C) (25)/(16) (D) (sqrt(41))/(4)

If P and Q are two points on the line joining A(-2,5),B(3,1) such that AP=PQ=QB then PB= sqrt(41) (2sqrt(41))/(3) (sqrt(41))/(3) (4sqrt(41))/(3)

If sqrt(2)=1.41 and sqrt(5)=2.24, find the value of (3)/(8sqrt(2)+5sqrt(5))+(2)/(8sqrt(2)-5sqrt(5))

If sqrt(2) = 1.41 then (1)/(sqrt(2))'= ?

If a=sqrt(17)-sqrt(16) and b=sqrt(16)-sqrt(15) then
