Consider a study to determine the compressive strength of concrete blocks used for paving Two methods of manufacturing concrete blocks are under investigation-method 1 (which is more expensive) and method 2. Research indicates that the greater the compressive strength of concrete, the greater the durability of a concrete block. Therefore the question is which if either, of the two methods produces greater compressive strength. In addition, the manufacturer considers that an average difference between the methods of less than 500...

Write and equation for each then solve: For a period of time, an island's population 1) grows at a rate proportional to its population. If the growth rate is 3.8% per year and the current population is 1543, what will the population be 5.2 years from now? 2) A savings account balance is compounded continuously. If the interest rate is 3.1% per year and the current balance is S1077.00, in how many years will the balance reach $1486.73?
