Show that the set is linearly dependent by finding a nontrivial linear combination of vectors in the set whose sum is the zero vector. (Use s1, S2, and s3, respectively, for the vectors in the set.) S = {(1, 2, 3, 4), (1, 0, 1, 2), (1, 4, 5, 6)} (0, 0, 0, 0) = Express the vector s3 in the set as a linear combination of the vectors s, and s2. S3 =
Let V be the set of all ordered pairs of real numbers (x1, u) with u > 0. Consider the following addition and scalar multiplication operations on u = (41, u2) and v= (v1, v2): %3D u+v = Using the above operations, if the set V satisfies Axiom 4 of a vector space (the existence of a zero vector), what would be the zero vector? Enter the components of the zero vector (in order) into the answer box below, separated with a comma. e.g., 142,322

Suppose V1, V2, V3, V4, V5 are distinct, nonzero vectors in R³ and suppose that span(V1, V2, V3, V4, V5) = span (V4, V5) and that v4 and v5 are not scalar multiples. Which of the following statement MUST be TRUE? Select all that apply. Each of the vectors 4, 5 is a linear combination of the vectors V1, V2, and v3. span(V1, V2, V3) = span (v4, 25). ✔ If we form a matrix A, with the vectors V₁, V2, V3, V4, V5 as columns, then the system Ax 0 has a nonzero solution. = There are more vectors than elements in each vector. So if we set up a system of equations we will have more variables than equations (more columns than rows in the matrix A). From this we can conclude that the equation Ax=0 will have a non- trivial solution. Each of the vectors ₁, 2, 3 is a linear combination of the vectors, and us. span(v1, v2, U3, U4, U5) is a plane.

Show that the set is linearly dependent by finding a nontrivial linear combination of vectors in the set whose sum is the zero vector. (Use s,, S2, and s3, respectively, for the vectors in the set.)

Select all statements which are TRUE. For statements with cross products, assume the vectors are in space, i.e., they have 3 components. Note on notation: A is a vector while A is a scalar. The magnitude of A is|A|. The dot product of two unit vectors is a unit vector. If c is a number between 0 and 1, then cA rotates A by 180 degrees. If A x B = 0 and both vectors are nonzero, then A and B are parallel. If A x B= 0, then at least one of A or B is the zero vector. If the nonzero vectors A and B make an angle of between them, then A. B > 0.
