Alright children what the answer?? ;)

I'm confused on this could anyone me and show me what i need to do to solve it.

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.

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585
