An airline charges $(22x + 20) for a ticket, $(x + 1) to check a bag, $ 2x for food, and $ (15x - 16) to upgrade to first class. write an expression to represent the total cost of flying first class, checking a bag, and buying food on the plane.

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
