Suppose that you are the power company and must provide power to a lighthouse on a rock one mile off shore. The nearest pole to run the line from is 2 miles up the shore from the line
straight out to the lighthouse. If the line costs $1000/mile on land and $1500/mile on water, find
the path for the line that minimizes the total cost. Your answer should state how far from the
pole your line leaves the shore and goes to the lighthouse. Show that this is a minimum and find
the cost for the path you have chosen

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
