Solve: \(8-6 x>4 x-12\)
Use a vertical format to find each product. $$\begin{array}{r} 9 y^{3}-7 y^{2}+5 y \\ 3 y^{2}+5 y \\ \hline \end{array}$$
We have seen that in \(2009,\) the United States government spent more than it had collected in taxes, resulting in a budget deficit of \(\$ 1.35\) trillion. If there are approximately \(3.2 \times 10^{7}\) seconds in a year, approximately how many years is 1.35 trillion seconds? (Note: 1.35 trillion seconds would take us back in time to a period when Neanderthals were using stones to make tools.)

We have seen that in \(2009,\) the United States government spent more than it had collected in taxes, resulting in a budget deficit of \(\$ 1.35\) trillion. a. Express 1.35 trillion in scientific notation. b. A trip around the world at the Equator is approximately \(25,000\) miles. Express this number in scientific notation. c. Use your scientific notation answers from parts (a) and (b) to answer this question: How many times can you circle the world at the Equator by traveling 1.35 trillion miles?
