4. Expand (x - 2)^{5}.

5. Compute

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

6. Compute
e^{0.1} to 4 places after the decimal point. Show your work.

7. Graph

x^{2} + y^{2} - 2x = 8
8. Graph

x^{2} - y^{2} = 4
9. Graph

4x^{2} + 9y^{2} - 16x + 18y = 11
10. Solve

2x + 3y + z = 10
