Question 7 [10 points] Let L; be the line passing through the point P;=(6, -2, 0) with direction vector #=[-1. -3, Z]T' and let L; be the line passing through the point P,=(~7. =5. 10) with direction vector @>=[-3. -1, 72]T. Find the shortest distance d between these two lines, and find a point Q7 on Ly and a point Q5 on Lj so that d(Q7,Q5) = d. Use the square root symbol 'v' where needed to give an exact value for your answer. a-0 Q7=(0.0,0) Q2=(0.0,0)
