Complete the area model to identify the quadratic expression it represents. a) 6x2 − 8x − 5 b) 6x2 − 8x + 6 c) 8x2 − 16x − 5 d) 8x2 − 16x + 6

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.
