Question

if two vectors 3i+3j+9k and i+aj+3k are parallel the value of a is​

Answer 1

3i+ 3j+ 9k and I+ aj + 3k are parallel the value of a is 15

Answer 2

Answer:

Mark as brainliest

Explanation:

Thus For two vectors to be parallel, the components of the vector should be known as each other. ... Yes these are parallel vectors because if we multiple in second with 3, we get b= 3i+6j+9k which is Vector a=2i+3j+4k, and vector b=3i+4j+5k
