i had k=2/9. for the matrices/area one i hadd 11/2 and 7/2. what did people get for w and z (complex numbers ones), and the coordinates for A and B on the hyperbola question coz mine was crazy like 16+8root34 which i highly doubt is right but i was rushing it

I don’t remember for sure but I think I got A (4c, c/4) and B ( -2c/3, -3c/2) or something like that

For the area one was it 7/2 or -7/2

for that matrices question where it asked what is c^39, did you have to calculate it or did you describe it?

My Answers (some are probably wrong):
1a) 2z^2-2z+13, so a = -2 and b = 13
1b) Z = 1, 1/2 +/- 5i/2

2a) SHOW THAT
2b) -2.712
2c) -2.680

3i) CAN'T REMEMBER
3iia) Rotation 90' clockwise about origin
3iib) BELOW:
0 1
-1 0

4a) n/3(n+5)(n-5)
4b) n = 5
4c) k= 2/9

5a) SHOW THAT
5b) I can't really remember... I want to say:
( 4c, c/4 ) and ( -2c/3 , -3c/2)

6a) detM = 12
6b) k= -3.5 OR 5.5

7a) SHOW THAT
7b) P(25a,10a)

8) PROOF

9a) w =(3p-10)/6 +(p-12)i/6
9b) p =10/3
9c) Z = 0.6 - 0.4i

If questions in wrong order... Oops.
