Answer question 10b showing fully all the steps. Solution should be simplified and easy to undertand as much as possible!

9 Given that 2x +ty 4t is a tangent to the rectangular hyperbola xy = 4 at the point P (2t,-), find the
real value(s) of 2.
The tangent meet the x-azis at A and y - azis at B. The line through A parallel to the y- axis meets
the hyperbola at C, while the line through B parallel to the z – axis meets the hyperbola at D. Show that
as P varies, the locus of the midpoint of CD is the perpendicular hyperbola 4xy = 25
10. (a) The figure shows a square lamina of side a with its vertex inclined at an angle 0,0 SOS pla
a line AB,
A.
Show that the centre of the lamina is at a distance
sin (9+) from AB.
2.
The lamina is rotated completely about the lipe AB, shows that the volume of the solid generated is
VZna? sin (9+)
(b) Find the greatest common divisor (gcd), t, of 427 and 1037. Hence find the integers and such that
427r+1037s =t.
Deduce that 7r+ 17s
