[7, 2] + ([-3, 6] - [2, -4]) = [2, 12]
Answer:
Step-by-step explanation:
i believe this is multiplication so. just multiply 12 3/4 x 2/5. The answer to that would be 12 6/20. Now let's simplify. you can divide this fraction to the fraction 2/2. 12 6/20 divided by 2/2 equals to 12 3/4. I hope this right, and I really hope you get an A on your test.
If it's division than here's the steps. KCFM (keep, change, flip, multiply) keep 12 3/4, change the division symbol to multiplication, and flip the fraction 2/5 to 5/2. last step multiply. 12 15/8. If you can simplify that then simplify it. I don't see anyone to simplify it so your okay.
Answer:
1.8 or 1 4/5 should be the answer!

Answer:
22.8 m/s at 17.4°
Step-by-step explanation:
You want to find the resultant of ...
3 cis 0° +20 cis 20° = (3, 0) +(18.794, 6.840) = (21.794, 6.840)
The magnitude is the root of the sum of the squares of the velocities in the horizontal and vertical directions:
s = √(21.794² +6.840²) ≈ 22.8
The direction is found from the fact that the tangent of the angle is the ratio of vertical to horizontal coordinates:
angle = arctan(6.840/21.794) ≈ 17.4°
The resultant velocity is 22.8∠17.4° meters per second.
