9a. False because rhombuses/kites can have diagonals intersecting at 90 degrees. Should be => (2 marks)
b. False; many examples whereis an integer and
is not, e.g.
so
, which isn't an integer. Should be <= (2 marks)

Agree with all except question 1. Question states r > 0. Thus it should be +square root. -

hmm, ok. So i worked out that i think i may get between: 56-61. I forgot some answer and it also depends on how strict the mark scheme is. I need 82 ums. hmmm, i do hope.

The square root sign already gives the positive root, you don't have to put the + sign.
I might have put it equal first and below that done >r but i doubt it. -

For 10c. I put my answer as a column vector with 0 on top and -36 on the bottom. Is this correct?

If I didn't simplify the coordinates down in question 5 and left them as x=14/16 and y=38/16 i'll still get the marks right?
