Find the coordinates of the point dividing the line segment joiningA(2,-4,3) and B(7,1,-2) in the ratio 2:3.
1b) Find the shortest distance between the planes
1c) Determine the value(s) of k so that the vectors u=(2k,-1,7) andv=(k,k,-3) are perpendicular
1d)Find the volume of the parallelepiped determined by thevectors
u = 2i - 3j k,
v = -i 3k and
w = 2i - j - k
(The AND or - signs are not appearing when the question is postedfor
equation u it has 2i,-3j, k
equation v it has -i, 3k
equation w it has 2i, -j,-k)
(the letters also have a little right arrow on each one of them,but I do not know how to put it using my computer)

For 1d), I got the Volume= 8, but people gave me answer for volumeas V=10
