Consider the vector 7 between (4,-1,-5) and (6,8,-2). 1. The vector is 2. The length of is 3. If the tail of is at (2, 4, 5), then the tip is at 4. If the tip of is at (3,-3,3) then its tail is at 5. What vector has the same length as . but points in the opposite direction? 6. What vector has the same direction as v, but is twice as long?
