1. The first step in the top-down approach to investing is assessing the state of the overall economy. Assume the following data for a hypothetical economy.

a) Determine in what stage the economy is in the business cycle. Explain your answer.

b) Give an example of an industry that is good for investment at this stage of the business cycle. Why?

ARE THESE STATEMENTS TRUE OR FALSE:

1. Epigenetic changes to the DNA are passed down to the offspring, however, they do not cause changes to the genes, or alleles. Is this statement true or false?

2.Genes are located on chromosomes. Is this statement true or false?

3.  If someone with type B blood has children with someone who is type A blood, is it possible for them to have a child that is type O? YES OR NO?

Write down the ground configuration of calcium (Z = 20). The line at 610nm in the spectrum
of neutral calcium consists of three components at relative positions 0, 106 and 158 (in units of cm−1). Identify the terms and levels involved in these transitions. The spectrum also contains a multiplet of six lines with wavenumbers 5019, 5033, 5055, 5125, 5139 and 5177 (in units of cm−1). Identify the terms and levels involved. Draw a diagram of the relevant energy levels and the transitions between them. What further experiment could be carried out to check the assignment of quantum numbers?

In the short run, a perfectly competitive firm will shut down and produce nothing if:

A certain property was offered in an instalment basis with no down payment for six years. However, the buyer needs to pay immediately a beginning of a monthly payment for a period of two years starting at an amount of P 4, 500 and succeeding monthly payments increases by P 800 until the last monthly payment. After such, payments become an end of a quarterly payments starting at an amount of P 25, 000 for the remaining period in which quarterly payments decreases by 6% every quarter thereof until the last quarterly payment. Money is 14% effective. (Please draw a cash flow diagram)

a) What was the cash price of the said property?

b) What equivalent uniform end of a semi-annual amounts would the payments be instead of the said condition above?

c) Find the sum of all the payments being made.

d) If after three years of payments, the buyer wishes to pay a single amount in order to settle all of his remaining obligations, how much would it be?

A) Find the area of the region enclosed by the parabola  and the line  

B) Write down an integral to compute the volume of the solid obtained by rotating the region below the curve about the y-axis. You do not need to evaluate the integral.

C) Write down an integral to compute the volume of the solid obtained by rotating the region below the curve  about the x-axis. You do not need to evaluate the integral.
