Problem 1
---------

1. b, c
2. a
3. b
4. e
5. c
6. d
7. Uniform scale by 2 followed by a 90-degree rotation.
8. A 45-degree rotation followed by a nonuniform scale by 2 in x and 4 in y followed by a -45-degree rotation.

Problem 2
---------

1. 0
2. 1*(10-8)*(10-8)/100 = 4/100
3.
1*f(12/10)*f(12/10) + 1*f(2/10)*f(18/10) + 1*f(8/10)*f(8/10) + 1*f(18/10)*f(2/10)
= (512*512 + 5832*8 + 1728*1728 + 8*5832)/36000000
= (262144 + 46656 + 2985984 + 46656)/36000000
= 3341440/36000000
= 5221/56250
= 0.0928
