Prove that for all scalars: a, b k = that: sigma^n_k = 1 a_k b_k lessthanorequalto [sigma^n_k = 1 a^2_k]^1/2 [sigma^n_k = 1 b^2_k]^1/2 a. prove the parallelogram law: ||u + v||^2 + ||u - v||^2 = 2||u||^2 + 2||v||^2 b. explain why it is called the parallelogram law. prove: = 1/4 ||u + v||^2 - 1/4 ||u - v||^2 write the formula for the euclidean norm in e. show that 1/||v|| v is a unit vector. use the properties of a norm to show that the metric: d(u, v) = ||u - v||

number one is the correct answer

step-by-step explanation: dogs and cats are mentioned, no other animals

sine

step-by-step explanation:

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

there is no points to select.
