Find a vector that has the opposite direction of u = (1,-2,4), but which has length square root of 3.

Normalize by dividing by its magnitude:

Multiply by -1 to reverse its direction, and again by to ensure this new vector has the magnitude we want. Notice that .

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
