MathematicsHard92×since 2002Q4701The equations of two sides of a variable triangle are x=0x=0x=0 and y=3y=3y=3, and its third side is a tangent to the parabola y2=6xy^2=6xy2=6x. The locus of its circumcentre is :A4y2−18y−3x−18=04{y^2} - 18y - 3x - 18 = 04y2−18y−3x−18=0B4y2+18y+3x+18=04{y^2} + 18y + 3x + 18 = 04y2+18y+3x+18=0C4y2−18y+3x+18=04{y^2} - 18y + 3x + 18 = 04y2−18y+3x+18=0D4y2−18y−3x+18=04{y^2} - 18y - 3x + 18 = 04y2−18y−3x+18=0Check answerSkip
