Answer:
Part 1)
Projection of vector A on vector B equals 19 units
Part 2)
Projection of vector B' on vector A' equals 35 units
Step-by-step explanation:
For 2 vectors A and B the projection of A on B is given by the vector dot product of vector A and B
Given
Similarly vector B is written as
Thus the vector dot product of the 2 vectors is obtained as
Part 2)
Given vector A' as
Similarly vector B' is written as
Thus the vector dot product of the 2 vectors is obtained as
Honestly? Just review your notes and try to work out the problems yourself before taking a look at the answer. You can also google specific topics that the test will cover and try the practice problems.
To compare these fractions, bring them to the same denominator. Expand the fractions to bring them to the common denominator (LCM):
7/8 = (2 * 7) / (2 * 8) = 14/16
13/16 = (1 * 13) / (1 * 16) = 13/16
Same denominator fractions sorted ascending:
13/16 < 14/16
Initial fractions in ascending order:
13/16 < 7/8
