At x=0,y=x^(3)-25 is:

If x+y=25 and x^(2)y^(3)+y^(2)x^(3)=25 , what is the value of xy?

If y=(2x^(9))/(3)-(5)/(7)x^(7)+6x^(3)-x find (dy)/(dx)atx=1

If y=|cos x|+|sin x|, then (dy)/(dx)atx=(2 pi)/(3) is (1-sqrt(3))/(2)(b)0(c)(1)/(2)(sqrt(3)-1) (d) none of these

The equation to the circle which touches the axis of y at the origin and passes through (3, 4) is 2(x^2+y^2)-3x=0 3(x^2+y^2)-25 x=0 4(x^2+y^2)-25y=0 4(x^2+y^2)-25 x+10=0

If (2.5)^(x)=(0.025)^(y)=10^(3) , then the value of (1)/(x)-(1)/(y) is

The point of contact 4x-5y+25=0 with the ellipse 9x^(2)+25y^(2)=225 is

The point of contact of the line 3x-4y-25=0 with the circle x^(2)+y^2=25 is
