A small boat leaves the dock at Camp DuNuthin and heads across the Nessie River at 15 miles per hour (this speed is with respect to the water) while maintaining a bearing of S67°W. (Thus we can think of the front of the boat as always pointing toward that heading.) The river is flowing due east at 8 miles per hour. What is the boat's true speed and heading? Express the heading as a bearing. (Hint: Model the boat's speed and course across smooth water by the vector b which has magnitude b = 15 and makes a 67° with the negative y-axis in Quadrant III. The river current is given by r = 8, 0 because we need r = 8 with its direction along the positive x-axis. The true course of the boat is given by b + r. Round your answers to two decimal places.)

The average hourly earnings for a construction worker is projected to be $24.50 in 2012. jason wants to join the construction work force after he graduates in 2012. his friend tells him that average hourly earnings for construction workers will rise by 2% from 2009 to 2012. based on the data below, assuming that the projected hourly earnings are correct, is jason’s friend’s statement accurate? construction industry - average hourly earnings, 2000-2009 a. his friend’s statement is accurate. the average hourly earnings will increase by 2%. b. his friend’s statement is not accurate. the percent increase will be more than 2% c. his friend’s statement is not accurate. the percent increase will be less than 2% d. his friend’s statement is not accurate. the average hourly earnings will decrease
