1.      Identify     the type of conic and find centre, foci, vertices, and directrices

9x2 – y2 – 36x – 6y + 18 = 0

2.      Find the equations of tangent and normal to the parabola x2 + 6x + 4y + 5 = 0 at (1 , -3 )

3.      A bridge has a parabolic arch that is 10m high in the centre and 30m wide at the bottom. Find the height of the arch 6m from the centre, on either sides.        

4.      At a water fountain, water attains a maximum height of 4m at horizontal distance of 0.50 m from       its origin. If the path of water is a parabola,        find the          height of water at a horizontal distance of 0.75 m from the point of origin.

5.      On lighting a rocket cracker it gets projected in a parabolic path and reaches a maximum height of 4m when it is 6m away from the point of projection. Finally it reaches the ground 12m away from the starting point. Find the angle of projection.
