Which matrix represents the rotation of the vector 1,4 by 2pi/3 radians

Option B is correct.

Rotation matrix =

Step-by-step explanation:

Given a vector : , rotation by radian.

A rotation matrix is a matrix that is used to perform a rotation in Euclidean space.

The standard rotation matrix is given by;

R =

Then, the matrix of rotation by radian  is:

=

Then; substitute

or

or

Simplify:

Therefore, the rotation matrix of a given vector is,

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w
