So here are some answers for Maths 12
They are in order but some r missing (don't remember all the question numbers)
1 (a)6/35 (b)15/16
2 (a)8/23 (b)11:12
3 4160
4 (a)1/3 (b)-1
5 (a)F (b)E
6 (a)Reflection image somewhere on right side (b)Rotation image vertices (-1,6),(-1,4),(-2,6)
(a)-1.3 (b)3.2 (c)-15
(a)64 (b)13 (c)underoot any number between 1 and 4,pi/2
(a)0.0041 (b)11,12
(a)3 (b)1
Sets: (a-Venn diagram) 3,2,1 (b)6 (c)1,5,7
(a)12 (b)3x/25
Matrix: (a)(4 -1 1 -1) (b)(0 -1/2 -1/3) ratio was 36/25 or 1.44
(a)62.7 (b)35
10
(b)3x^-1y^2
(a)5pi/8 (b)3
12.1
7x+3/something don't remember
(a)-1.1 (b)18
(a)AO common, BA and DA tangents, BO and DO radius (b)Kite (c)44
Distance-time graph:From 12 to 0 on y-axis, don't remember the x-axis Varun's speed:18 Speed-time Graph:Rectangle height 18 and then 0 for some time,rectangle height 20
Locus:Arc and something else Shaded region:upper left corner
Last question: (d)(i) 3x^2-6 (ii)3 +-underroot6
Mean median question:Letters received=34
