If `|z| =2`, then locus of `-1 + 5z` is a circle whose centre is

Let z=x+iy be a complex number such that |z+i|=2 . Then the locus of z is a circle whose centre and radius are

If |z|=5, then the locus of -1 + 2z is (A) a circle having center (2,0) (B) a circle having center (-1,0) (C) a circle having radius 5 (D) a circle having radius 9

If |z|=5, then the locus of -1 + 2z is (A) a circle having center (2,0) (B) a circle having center (-1,0) (C) a circle having radius 5 (D) a circle having radius 9

If |z-1|=2 then the locus of z is

If |z-1| = 2 then the locus of z is

If z_1=10+6i and z_2=4+2i be two complex numbers and z be a complex number such that a r g((z-z_1)/(z-z_2))=pi/4 , then locus of z is an arc of a circle whose (a) centre is 5+7i (b) centre is 7+5i (c) radius is sqrt(26) (d) radius is sqrt(13)

If z_1=10+6i and z_2=4+2i be two complex numbers and z be a complex number such that a r g((z-z_1)/(z-z_2))=pi/4 , then locus of z is an arc of a circle whose (a) centre is 5+7i (b) centre is 7+5i (c) radius is sqrt(26) (d) radius is sqrt(13)

If |3z-2|=5 then the locus of z is

If z = (lambda + 3) + isqrt( 5 - lambda^(2)) , then the locus of z is a circle with centre at
