- ProofProve in full detail that M2,2, with the standard operations, is a vector space.arrow_forwardProof In Exercises 6568, complete the proof of the remaining properties of theorem 4.3 by supplying the justification for each step. Use the properties of vector addition and scalar multiplication from theorem 4.2. Property 6: (v)=v (v)+(v)=0andv+(v)=0a.(v)+(v)=v+(v)b.(v)+(v)+v=v+(v)+vc.(v)+((v)+v)=v+((v)+v)d. (v)+0=v+0e.(v)=vf.arrow_forwardVector Operations In Exercises 2932, find a uv, b 2(u+3v), c 2vu. u=(6,5,4,3),v=(2,53,43,1)arrow_forward
- Let A = [[3,1,1,2,2],[-3,-2,4,2,2],[-5,5,4,-1,-2]] Give a nonzero vector x in the nullspace of A.arrow_forwardUsing the 10 properties:(a) Show that the set of strictly positive reals: R+ = {a E R | a > 0}, provided with the operations defined below is a vector space:- Addition: a + b = ab for all a, b E R+- Multiplication by a scalar: k*a=ak, for all k E R and a E R+ (b) Why is the set of positive reals { a E R | a ⩾ 0}, endowed with the same operations, not a vector space?arrow_forwardfind all the scalars k such that || kv || = 3, Where v = (-1, 2, 0, 3)arrow_forward
- Determine whether each statement is true or false. If a statement is true, give a reason or cite an appropriate statement from the text. If a statement is false, provide an example that shows the statement is not true in all cases or cite an appropriate statement from the text.(a) The dot product is the only inner product that can be defined in Rn. (b) A nonzero vector in an inner product can have a norm of zero.arrow_forwardA vector u for which || u || = 1 is called a(n)_______ vector.arrow_forward2. Determine whether the expression is defined or undefined. If it is defined, then determine whether it is a vector or a scalar. If it is undefined, explain why. a xỉ a. b. ||à × ī|| c.
