Under certain water​ conditions, the free chlorine​ (hypochlorous acid,​ HOCl) in a swimming pool decomposes according to the law of uninhibited decay. After shocking a​ pool, the pool​ boy, Geoff, tested the water and found the amount of free chlorine to be 2.4 parts per million​ (ppm). ​ Twenty-four hours​ later, Geoff tested the water again and found the amount of free chlorine to be 2.1 ppm. What will be the reading after 2 days​ (that is, 48 ​hours)? When the chlorine level reaches 1.0​ ppm, Geoff must shock the pool again. How long can Geoff go before he must shock the pool​ again?

BTS corporation has two investment plans A,B and expected to get $1200 of cash flow in 1 year. The investment plan A's β is 1.0 and plan b β is 1.5. If the risk-free interest rate is 10% and market risk premium is 10%, please answer the following question.

question. explain why the statement is regarded as value additivity principle

A real estate development firm is looking to invest in a new apartment complex that requires an initial investment of $8 million today. This project will yield free cash flows of $1 million each year for the next 15 years (from t=1 to t=15). The firm is financed half with equity and half with bonds (assume no cash). The firm's beta is 1.5, the yield to maturity on its debt is 6.0%, and its tax rate is 20%. If the expected return on the S&P500 Index is 7.0% and the risk-free rate is 1.0%, what is the NPV of this project (in millions)?

A) $4.67 million

B) -$1.12 million

C) 0

D) $.88 million

E) 1.75 million

Suppose the spot exchange rate between Brazilian real and euros is S0BRL∕EUR= BRL 2.9488∕EUR. Calculate forward exchange rates at 1-year,2-year, and 3-year horizons under these two scenarios. a. Yield curves in euros and real are flat. Annual Eurocurrency interest rates are iBRL= 5 percent and iEUR= 1 percent for the next several years.

b. The euro yield curve is flat at iEUR= 1.0 percent per year. Brazilian real interest rates are 5.5 percent per year at a 1-year horizon, 5.0 percent at a2-year horizon, and 4.8 percent at a 3-year horizon.

Consider a Solow economy with the following production function

F(K,N) = zK^(1/3)N^(2/3)

and parameters d = 0.05, s = 0.2, N0 = 100 and z = 1.0. Suppose K = 300 in period 0 and the

unit period is one year. In contrast to the standard Solow model, we assume that the population

growth rate n is no longer exogenous but rather endogenous and determined by

(1 + n) = N’/N = g(C/N) = (C/N)^3 as it is the case in the Malthusian model.

Question: Find k* the steady state per-capita capital stock, consumption per capita (c*) and output

per capita (y*).

When answering the following questions, assume all dilutions are in even power of 10, unless told otherwise, and that 0.1 mL (100uL) or 1.0 mL (1,000 uL) volumes were plated. Also, cell density and cell concentration are used interchangeably, as are CFU and colonies, depending on how the term is being used.

Please answer the question using the formula V₁D₁ = V₂D₂.....Please show details
