Prove that the curve y= x^{2 }- 3x + 1 and x(y + 3) = 4 intersect at the right angles at their points of intersection.The curve y=Ax^{2}+ bx - 10 passes through the point (2 , 0) and the gradient of the curve at this point is 3. Calculate the values of A and B.hi mam whats d problem with dis servise as i m studng d chapter of circle it is showng maths processng error so plzz hlp m out of dis as i was studng cbse in dissite it is much better than maharastra so plzzzmake dis maharashtra board also better as cbse and plzz hlp m out of dis

^{2}+y^{2}-4y= 0 (b) x^{2}+y^{2}+4x = 0 (c) x^{2}+y^{2}-4y-12= 0 (d) x^{2}+y^{2}+4x= 128. The line 2x-y+6=0 meets the circle x

^{2}+y^{2}+10x+9=0 at A and B. Find the equation of circle on AB as diameter.(A) 4 (B) 1/4 (C) 1 (D) 16

Q17. The radius of the circle passing through the vertices of the triangle ABC, is

(A) $\frac{8\sqrt{15}}{5}$ (B) $\frac{3\sqrt{15}}{5}$

(C) $3\sqrt{5}$ (D) $3\sqrt{2}$

I wanted to know wheather in maths do we have circle & conics

Plez let me know...?
