Cholesterol Researchers have found that the risk of coronaryheart disease rises as blood cholesterol increases. This risk maybe approximated by the functionR(c) = 3.19(1.006), 100 scs 300,where R is the risk in terms of coronary heart disease incidenceper 1000 per year, and c is the cholesterol in mg/dL. Supposea person's cholesterol is 180 mg/dL and going up at a rate of15 mg/dL per year. At what rate is the person's risk of coronaryheart disease going up? Source: Circulation.

The risk of heart attack and the level of cholesterol are related to each other by the equation…

Jimmy is going to invest $200 into an account where his money will grow 10% each year. If he leaves his money in the account and tracks it's growth, we can model the amount of money he has with the function T(y)=200(1.10)^v, where T represents the amount of money, and y represents the number of year's he invests his money. How much money will he have after investing for 10 years? In other words, evaluate T(10)=200(1.10)^10, rounding the proper decimal place for money.

There is a relationship between perceived corruption and human development in a country that can be modeled by H(x) = 0.3 +0.28 In x. In this formula, x represents the Corruption Perception Index, where 1 is very corrupt and 10 is least corrupt. The output gives the Human Development Index, which is between 0.1 and 1 with 1 being the best for human development. (a) For country A, x = 5. Evaluate H(5) and interpret the result. (b) The Human Development Index is 0.69 for country B. Find the Corruption Perception Index for country B. (a) H(5)~ (Simplify your answer. Round to two decimal places as needed.)
