**1-**The parabola shown has equation "y= 4x - x2 and intersects the x-axis at the Origin and the Point P.

*It has a Max T.P. as -x2 and on right part of parabola when falling down and cuts x-axis, is point P. In paraobla on top left has point Q. And if you follow line it cuts y-axis which is R.*

**(a)**Find the Co-ords of P

**(b)**R is the point (0, 2)

Find the equation of PR

**©**The line and the parabola intersect at Q.

Find the Co-ords of Q

**2-**The 2 lines AB and ED cross at the point T.

A is (0, 2), B(11, 7), E(4, 1) and D(7, 8).

**(a)**Wrtie down the gradients of the lines AB and ED.

**(b)**

*Hence*find the size of the acute angle DTB between the 2 lines.
