Answer:
n = 1
Step-by-step explanation:
1/2 (-3/2n + 1) = 3/4 - n
-3/4n + 1/2 = 3/4 - n
n - 3/4n = 3/4 - 1/2
1/4n = 1/4
n = 1
1/2 (-3/2(1) + 1) = 3/4 - (1)
1/2 ( -3/2 + 1) = -1/4
1/2 ( -1/2) = - 1/4
-1/4 = -1/4
For 12:
Since the line y = mx + c is a tangent, then the distance from the centre of the circle to the line is equal to the radius.
Using perpendicular distance:


Squaring both sides, we get:


, as required.
