General Electric (GE) is considering a new energy project that requires an initial investment of $20,000,000. The project is expected to generate the following annual cash inflows:

Year	1	2	3	4	5	6	7	8	9	10
Cash Inflows ($)	2,500,000	2,600,000	2,700,000	2,800,000	2,900,000	3,000,000	3,100,000	3,200,000	3,300,000	3,400,000

The discount rate for the project is 9%. The project has a residual value of $2,000,000 at the end of its 10-year life. The corporate tax rate is 30%.

Required:

1. Calculate the net present value (NPV) of the project.
2. Compute the internal rate of return (IRR).
3. Determine the payback period for the project.
4. Assess the impact of the residual value on the project's NPV.
5. Evaluate the sensitivity of the project's NPV to changes in the discount rate.
