The discount rate Main article: Discount rate The rate used to discount future cash flows to their present values is a key variable of this process. A firm’s weighted average cost of capital (after tax) is often used‚ but many people believe that it is appropriate to use higher discount rates to adjust for risk or other factors. A variable discount rate with higher rates applied to cash flows occurring further along the time span might be used to reflect the yield curve premium for long-term

Resting metabolic rate can vary with age independently from body mass changes in the Colorado potato beetle‚ Leptinotarsa decemlineata. Abstract A study was done by Saija Pironine‚ leena Lindstrom‚ and Anne Lyytinen in the Journal of Insect Physiology‚ to investigate the age dependence of resting metabolic rate in Colorado potato beetle (Leptinotarsadecemlineata) from adult emergence until age 10 days. In their hypothesis they expected to see a bell shaped pattern in metabolic rate with adult age

Initial Investment The desired item is jewelry The cost in 12 years will be about $6000. The average interest rate is 5%. The Present value formula is P =A (1+r)-n where P is the present value that will amount to A dollars in n years at interest rate r compounded annually. Note that the quantity raised to a power has the negative exponent on –n. According to the rules of exponents‚ this means that once the negative is put into effect‚ the base quantity will change position by dropping down

exchange rates‚ which is useful for international finance assignment. Exchange Rate is the price of one country’s currency in terms of another country’s currency; the rate at which two currencies are traded for another. It measures the number of units of one currency which exchange‚ in the foreign exchange market for one unit of another. Exchange rates are important because‚ they establish the relationships between the different currencies or monetary units of the world. Exchange rates have been

Chemical Kinetics Factors Affecting Reaction Rate OVERVIEW Chemical reactions occur at different rates. In this experiment you will consider some of the key factors that influence the rate of a reaction: nature of reactants - particle size temperature concentration catalysts According to the collision theory‚ the rate of a reaction depends on the frequency of collisions between reacting particles. The more frequent the collisions‚ the faster the rate of the reaction. However‚ in order for the

Mortality rate is a measure of the number of deaths (in general‚ or due to a specific cause) in a population‚ scaled to the size of that population‚ per unit of time. Mortality rate is typically expressed in units of deaths per 1000 individuals per year; thus‚ a mortality rate of 9.5 (out of 1000) in a population of 1‚000 would mean 9.5 deaths per year in that entire population‚ or 0.95% out of the total. It is distinct from morbidity rate‚ which refers to the number of individuals in poor health

Discussion The purpose of this experiment was to determine if splitting a bean would affect its rate of respiration. Splitting a bean does not impact its rate of respiration. This is shown in the data‚ while the average rate of respiration for Whole beans is 1.35 and the rate of respiration for 1.16‚ the standard error of the mean is .15. Because the standard error of the mean is so high‚ they overlap in both of the data sets‚ which shows that the data is very similar. This is better shown in the
