From 1985 to 2003, the number BB of federally insured banks could be approximated by B(t)=−323.4t+13794B(t)=-323.4t+13794 where t is the year and t=0 corresponds to 1985.How many federally insured banks were there in 1990?   Find the slope of the graph of B. Interpret this slope as a rate of change. Choose the correct answer below. The number of banks decreased by 323.4 banks per year The number of banks increased by 12177 banks per year The number of banks increased by 323.4 banks per year The number of banks decreased by 12177 banks per year The number of banks decreased by 13794 banks per year The number of banks increased by 13794 banks per year Find the y-intercept of the graph of B.The y-intercept is Interpret the y-intercept. Choose the correct answer below. The y-intercept is the number of banks in 1985 The y-intercept is the number of banks in 2003 The y-intercept is the number of banks in 1990 The y-intercept is the minimum number of banks allowed in the country The…

When driving down a mountain road, you notice warning signs indicating that it is a "11% grade." This means that the slope of the road is −11/100. Approximate the amount of horizontal change in your position if you note from elevation markers that you have descended 2000 feet vertically. (Round your answer to one decimal place.)
