A water well drilling rig has dug to a height of -40 feet after one full day of continuous use. Assuming the rig drilled at a constant rate, what was the height of the drill after 15 hours?

Find the solution of this system of equation -7x+y=-20 9x-3y=36

What are the values of each variable in the diagram below?

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.
