A boat heading out to sea starts out at point A, a horizontal distance of 1206 feet from the lighthouse/ the shore. from that point, the boat screw measures the angle of elevation to the lighthouse is Beacon light from that point to be 9°. At some later time, the crew measures the angle of elevation from point B to be 4°. Find the distance from point a to point B. Round your answer to the nearest 10th of a foot if necessary.

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?
