A weight of 100 pounds is suspended by two ropes A and B. Rope A makes an angle of 30 degrees with the ceiling and rope B makes an angle of 45 degrees with the ceiling. What are the magnitudes of...

The position vectors of A and B relative to an origin O are (p, q) and (q, r) respectively where q≠0. Find an equation connecting p, q, and r in each of the cases: (i). O, A and B are collinear...

If not, when would linear dependency imply coplanarity?

if a=i+2j+3k, b= -i+k , c= j+k and d= -2i+j+k, then d equals.. A.a+3b-c B.-2a+c C.-3a-b+5c D.-a+b+3c E.5a-7b-9c
