to 4 places after the decimal point using the binomial theorem.

6. Compute e0.1 to 4 places after the decimal point. Show your work.

7. Graph

x2 + y2 - 2x = 8

8. Graph

x2 - y2 = 4

9. Graph

4x2 + 9y2 - 16x + 18y = 11

10. Solve

2x + 3y + z = 10

x - y + z = 4

4x - y - 5z = -8

using

11. Express

as a sum of rational functions with linear denominators.
