Vector v has a direction of (-3,21). find the direction angle for v

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 (:

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
