In January 2011, Solaris Co. pays $2,750,000 for a tract of land with two buildings on it. It plans to demolish Building 1 and build a new store in its place. Building 2 will be a company office; it is appraised at $531,000, with a useful life of 20 years and an $70,000 salvage value. A lighted parking lot near Building 1 has improvements (Land Improvements 1) valued at $619,500 that are expected to last another 12 years with no salvage value. Without the buildings and improvements, the tract of land is valued at $1,799,500. Solaris also incurs the following additional costs: Cost to demolish Building 1$341,400Cost of additional land grading 191,400Cost to construct new building (Building 3), having a useful life of 25 years and a $398,000 salvage value 2,242,000Cost of new land improvements (Land Improvements 2) near Building 2 having a 20-year useful life and no salvage value 173,000
Convergent boundaries happen when two pieces of Earth’s crust move together. The three types of convergent boundaries are; ocean to continental crust; ocean to ocean crust; and continental to continental crust.
Ocean to Continental Crust: Ocean to continental crust boundaries create a subduction zone where ocean crust is pushed under continental crust. Continental volcanic Arcs are formed on land such as the Andes mountain range.
Ocean to Ocean: Ocean to ocean crust also has one piece of ocean crust pushing under another piece of ocean crust because of density differences (one piece of ocean crust is less dense than the other to cause this).
This action causes Volcanic Island Arcs such as the Aleutian Island chain .
Continent to Continent: Continent to Continent crust occur with the convergence of two continental plates. This causes large folded mountain ranges such at the Alps and the Himalayan mountain ranges. Continental crust can never subduct.
For this assignment you are going to practice some of the data analysis that astronomers have to do to look for evidence of extrasolar planets. You are given six example graphs of data that use three different methods: the astrometry method, the âwobbleâ or spectral method, and the transit method.
I have provided some notes in the reading section on each of these methods, using the same types of diagrams I provide for the assignment. You will also be able to find a lot online about these methods and the discoveries made with them.
There are two examples for each of three methods: Astrometry, Spectral, and Transit methods.
For each example you are to determine if there is sufficient evidence to claim that there is an extrasolar planet orbiting the star. You are going to do this six times, once for each of the graphs. They are not connected to each other.
Part 1 : For each graph answer (15% each) :
Is there evidence of a possible extrasolar planet orbiting this star? (Yes or no)
If there is not sufficient evidence to say there is an orbiting star, you should include a paragraph explaining why there is insufficient evidence of an extrasolar planet. There is no need to try to explain what could cause the patterns you do see in the data, but you have to explain why they are different than what you might see if there were a planet orbiting the star. (about 100 words)
If there IS evidence of an extrasolar planet, you must include a paragraph about the evidence you used to come to that conclusion as well as the orbital period of the planet (how long it takes to make a complete orbit around the star). (about 100 words)
Part 2 (3 pts): Answer the following question (10%)
Are any of these graphs likely from the same star? Explain your answer. Remember to think about the orbit and the way we view the star. (about 100 words)

You need a 30-year, fixed-rate mortgage to buy a new home for $240,000. Your mortgage bank will lend you the money at an APR of 6.53 percent for this 360-month loan. However, you can afford monthly payments of only $1,150; so you offer to pay off any remaining loan balance at the end of the loan in the form of a single balloon payment. How large will this balloon payment have to be for you to keep your monthly payments at $1,150?
