How do you solve this? me (i will give you 14 points)

Of four points are collinear, they are also coplanar

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.

The equation of a parabola is given. y=18x2+4x+20 what are the coordinates of the focus of the parabola?
