Answer:

5, 144°

Step-by-step explanation:

A vector with magnitude v and angle θ can be split into x and y components as:

vx = v cos θ

vy = v sin θ

Here, we're given the components and asked to find the magnitude and direction.  By matching, we can see the magnitude is 5 and the angle is 144°.

So the answer is 5, 144°.

Answer: I just took the test and got 100%

1. C, The vector will not change direction but will increase in magnitude.

2. C, 56 ft lbs

3. C, (-2,-3)

4. A, u = -4 sqrt 41/41 i - 5 sqrt 41/41 j

5. A, 56

6. C, 11.4 ft/sec

7. Do not copy my exact answer please (: They are equal. You know because if you take the points of each segment and subtract them, you will get the same points for both segments.

8a. A, (-10,-16)

8b. D, 2 sqrt 89

9a. C, (-14,-21)

9b. B, 7 sqrt 13

10a. C, (-18,-26)

10b. B, 10 sqrt 10

11. B, 5,144 degrees

12. A, 173 degrees

13. C, (1/6, -1/5)

14. D, 163 mph

15. C, 10j

16. D, 2 sqrt 3

17. A, 98.1 degrees

18. Do not copy my exact answer please (: The angle between the two vectors is 26.75 degrees.

Feel free to mark as brainliest (:

Answer:

Step-by-step explanation:

A, B and C must be real numbers, and A and B are not both zero (which would cause division by zero in the calculation of the slope).
