What is the greatest common factor of 20y^9+5y^6?

Ineed solving this problem h/8=-25 solve for h idk how to this can someone show me and also give an answer you

What is the measure of angle tvu shown in the diagram below

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.
