1 [3]
The coefficient of x2x^{2} in the expansion of (1−4x)6(1 - 4x)^{6} is 12 times the coefficient of x2x^{2} in the expansion of (2+ax)5(2 + ax)^{5}. Find the value of the positive constant aa.
2 [5]
The curve y=x2y = x^{2} is transformed to the curve y=4(x−3)2−8y = 4(x-3)^{2} - 8. Describe fully a sequence of transformations that have been combined, making clear the order in which the transformations have been applied.
7
The equation of a circle is (x−6)2+(y+a)2=18(x-6)^{2} + (y+a)^{2} = 18. The line with equation y=2a−xy = 2a - x is a tangent to the circle.

The equation of a curve is y=(5−2x)32+5y = (5-2x)^{\frac{3}{2}} + 5 for x<52x < \frac{5}{2}.
10(a) [4]
A point PP is moving along the curve in such a way that the yy-coordinate of point PP is decreasing at 5 units per second. Find the rate at which the xx-coordinate of point PP is increasing when y=32y = 32.
