Question
Solve. log 3x = 1 Select the correct choice below and, if necessary, fill in the answer box within your choice. The solution set is {x} (Simplify your answer. Type an integer or a fraction. Use a comma to separate answers as needed.) The solution is the empty set. Solve the following logarithmic equation. Be sure to reject any value of x that is not in the domain of the original logarithmic expression. Give the exact answer. Then, use a calculator to obtain a decimal approximation, correct to two decimal places, for the solution. 9 + 3 In x = 33 What is the solution in terms of e x = Solve the following logarithmic equation. 3+ In (27x) = 18 - 2 In (x) (Do not round until the final answer. Then round to three decimal places as needed.) Solve the logarithmic equation. 2 log x = log (10x -250) + 1 x = (Simplify your answer.) During a 5-year period of constant inflation, the value of a $111, 000 property increases according to the equation v = 111, 000 e 0.03t dollars. In how many years will the value of this building be double its current value? It years the value of the building will double its current value. (Type an integer or a decimal rounded to two decimal places as needed.) Based on data for the years 1910-2007, the expected life span of people in Country A can be described by the function f(x) = 10.965 + 14.324 lnx, where x is the number of years from 1900 to the person's birth year. Estimate the birth year for which the expected life span is 77 years. Use graphical methods to determine the birth year for which the expected life span is 77 years. Does this agree with the solution in part (a)? The birth year is approximately for which the expected life span is 77 years. (Round to the nearest whole number as needed.)Explanation / Answer
