Which ordered pair is a solution to this equation? 3x + 7y = 13 (4, 1) (3, 1) (13, 2) (2, 1)

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.

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.

Calculate the missing value. round the answer to on decimal place. start with 70, increase it by 21%, and end up with
