Quizplus · Accepted Answer

To find the magnitude of u, we need to take the square root of the dot product of u with itself: ||u|| = sqrt(u dot u)
Using the given information, we can find u dot u to be 11eacce6_1efe_2d38_9f49_a1f5f965d222_TB7896_11
Taking the square root of this value gives us 11eacce6_1efe_2d38_9f49_a1f5f965d222_TB7896_11, which is Choice D.
