3y- 12x = 18
2y-8x= 12

Identify a1 and r for the geometric sequence an= -256(-1/4) n-1

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.

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.
