In Exercises 33 - 38, complete the table for the radioactive isotope. Isotope \( ^{14} C \) Half-life (years) \( 5715 \) Initial Quantity \( 6.5 g \) Amount After 1000 Years
The populations (in thousands) of Orlando, Florida from \( 2000 \) through \( 2007 \) can be modeled by \( P = 1656.2e^{kt} \), where \( t \) represents the year,with \( t = 0 \) corresponding to \( 2000 \). In \( 2005 \), the population of Orlando was about \( 1,940,000 \).(Source:U.S. Census Bureau) (a) Find the value of \( k \) Is the population increasing or decreasing? Explain. (b) Use the model to find the populations of Orlando in \( 2010 \) and \( 2015 \). Are the results reasonable?Explain. (c) According to the model, during what year will the population reach \( 2.2 \) million?
In Exercises 113 - 116, use a graphing utility to graph and solve the equation. Approximate the result to three decimal places. Verify your result algebraically. \( \ln\left(x + 1\right) = 2 - \ln x \)
In Exercises 81 - 112, solve the logarithmic equation algebraically. Approximate the result to three decimal places. \( 2 - 6 \ln x = 10 \)
In Exercises 117 - 120, \( \$2500 \) is invested in an account at interest rate \( r \), compounded continuously. Find the time required for the amount to (a) double and (b) triple. \( r = 0.0375 \)
