Figure ABCD is rotated clockwise about the origin through 90°. Identify the coordinates for the given figure after 90° rotation

nydimaria [60]

Answer:

D[3, 3], C[1, 4], B[0, 1], A[4, -1]

Step-by-step explanation:

Whenever you are doing a 90° clockwise rotation ABOUT THE ORIGIN, it is in the form of [y, -x], meaning you take the y and make it your x, then take your original x and put its OPPOSITE.

90° counterclockwise rotation → [-y, x]

90° clockwise rotation → [y, -x]

I hope this helps, and as always, I am joyous to assist anyone at any time.

A force F1 of magnitude 6.00 units acts at the origin in a direction 30.0 above the positive x axis. A second force F2 of magnit

kumpel [21]

F1 = 6*cos(30) i + 6*sin(30) j = 5.20 i + 3 j
F2 = 0 i + 5 j 

R = F1 + F2 
Add the 'i's together (x direction) and the 'j's together (y direction) 
R = (5.20 + 0) i + (3 + 5) j = 5.2 i + 8 j 

Magnitude: 
||R|| = √(5.2^2 + 8 ^2) = √91 = 9.54 

Direction: 
Θ = atan ( Rj / Ri ) = atan( 8 / 5.2 ) = 57.0⁰
