Here are some problems from a practice test that I couldn't get(Kept getting weird numbers), if anyone knows help would be appreciated

1. Find a vector V tangent to graph at the point (2, 19)

2. Object A is at

Object B is at

They crash at point (10, 3, 4) when t=2. What is the angle of the crash?

3. Determine the distance from P=(9, 2, 7) to the plane x+2y+3z=6
