1) Find equations of tangent lines to the circle x² + y² = 49 from the pole F. = (-3,4). 2) For the circles S, : x'+y? - 4x - by + 3 = 0 S2: x+y? + bx + 4y - 7 = 0 a) Find centers and radi. b) Find the radical axis. 3) For the ellipse 24x²+49 4² = 1176, find: a) half- -axes lengths, distance between focal points, equation of directrix, and eccentricity b) two other vertices of equilateral triangle if one vertex is Al-7,0). equation of the sphere if 3x - 2y + 2 2 2 2 = 14 is a tangent plane it at the point to = (2, -1,3). (Do not! multiply plane eq. by 2). 011 4) Find an
