Calculate the load, \rm p, that would cause \rm a to be displaced 0.01 inches to the right. the wires \rm ab and \rm ac are a36 steel and ½" in diameter. the wires are 12 inches long before \rm p is applied and both are oriented at 30 degrees from horizontal (i. e., total angle at a is 60 degrees).

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?
