Please help. will give brainliest if I can. Identify the transformation that was applied to this letter.

A. Translation
B. Reflecting over the x-axis
C. Rotation about the orgin
D. Reflection over the y-axis

Explain how you can use the associative property to evaluate (7x50)x4.

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.

Solve the following pair of equations for x and y: ax/b_ by /a= a +b; ax - by = 2ab
