1. Solve the equation by completing the square. Round to the nearest hundredth if necessary. x2 + 3x – 5 = 0

A. 1.66, 2.69
B. –8.75, 5.75
C. 1.05, –4.05
D. 1.19, –4.19

Solve for x -2.3(r - 1.2 ) = -9.66 enter you answer as decimal.

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.
