If you really want an expert to help you, be sure to follow directions and type your <u>subject</u> in the <b>School Subject</b> box. Any other words, <u>including obscure abbreviations</u>, are likely to delay responses from a teacher who knows that subject well.

Why do you write asu for the subject? Are you going to Arizona State U?
The DOT product of those two vectors, u*v, would be +28, a scalar. The CROSS product u x v would be a vector. You have not said what the question is. You have only defined two vectors.

I get -134 for the dot product.

Damon is correct. I missed a dangling - sign in front of a 9 in the v vector.
