Solve each equation. Approximate answers to four decimal places when appropriate. (a) \(\log x=2\) (b) \(\log x=-3\) (c) \(\log x=1.2\)
Solve each equation. Approximate answers to four decimal places when appropriate. $$2 \log _{4} x=3.4$$
Near New Guinea there is a relationship between the number of bird species found on an island and the size of the island. The table lists the number of species of birds \(y\) found on an island with an area of \(x\) square kilometers. $$\begin{array}{rccccc}x\left(\mathrm{km}^{2}\right) & 0.1 & 1 & 10 & 100 & 1000 \\ \hline y \text { (species) } & 10 & 15 & 20 & 25 & 30\end{array}$$ (a) Find a function \(f\) that models the data. (b) Predict the number of bird species on an island of 5000 square kilometers. (c) Did your answer involve interpolation or extrapolation?
Solve each equation. Use the change of base formula to approximate exact answers to the nearest hundredth when appropriate. $$8-3(2)^{0.5 x}=-40$$
Solve each equation. Use the change of base formula to approximate exact answers to the nearest hundredth when appropriate. $$10^{3 x}=100$$
