Step by step
Solved in 3 steps with 3 images
- Which of the following are vector subspaces of R3? all vectors of the form (a, b, c), where b = a + c? all vectors of the form (a, b, c), where b = a + c + 1? Note: In the image the problem is described more clearly, do not skip any step and solve the two parts a and b.The solutions of the equation 2x-y+z=0 define a subspace of dimension two in R3 called a plane that is called P. a) Find a vector in P that is unit b) find a vector in P of norm 100 c) find an orthonogonal basis for PQUESTION 1Show that W = {(a, 0, b)|a, b ∈ R} is a subspace of R3
- The subspace of R3 generated by the vectors u1= (4/5, 0, −3/5) and u2= (1, 0, 1) is a plane through the origin. Express w = (1, 2,3) in the form w = w1+w2, where is w1 in the plane and w2 is perpendicular to the plane. Note: do not skip any step, solve step by step, the image shows the problem more clearly.The sum of the subspaces L{(1,0,−1),(1,1,0)} and L{(2,−1,0),(0,1,1)} in the space R^3 is equal to: (a) L{(1,1,0),(0,-1,1)}. (b) L{(0,1,−1)}. (c) {(x,y,z)∈ R^3 | y=z} (d) R^2 (e) R^3.What is the dimension of the sum of subspaces V and W in R^4, if V=span{(1,−1,0,1),(1,0,−1,1)} and W=span{(1,−2,1,1),(0,1,−1,0)}? (a) 0(b) 1.(c) 2.(d) 3.(e) 4
- Part:b: For matrix A given in the picture attached. Find Column space, Null space and Row space of A Also write Basis for each subspace.I need help for problem (h). Check that the set at (h) is a subspace of Rn or not.I am having troubles understanding intersection of subspaces. For instance, I have these two subspaces, U = {(a,−a,b,c) | a,b,c ∈ ? } and W = {(p,q,-p,r) | p,q,r ∈ ? }. Is U ∩ W = {0}? If it isn't, then what is their intersection?
- (a) Which rules are broken if we keep only the positive numbers x > 0 in R 1 ? Every c must be allowed. The half-line is not a subspace.(b) The positive numbers with x + y and cx redefined to equal the usual xy and xc do satisfy the eight rules. Test rule 7 when c = 3, x = 2, y = 1. (Then x + y = 2 and cx= 8.) Which number acts as the "zero vector"?True or False? 1) if a square matrix B is obtained from A by interchanging two rows, the det(B) = det(A). 2) the set of points on the line represented by x + y = 0 is a subspace of R2Question: Is the subset P(x,y,z) described by 8x-y+2z=0 a subspace of R3? Why or why not? Is my interpretation of subspace correct? Are there any explicit theorems that explain this concept? This is what I came up with: The subset P(x,y,z)described by 8x - y + 2z = 0 is a subspace of R3 because the plane passes through the origin which is used as the positional matrix. Any scalar of x,y, or z will equal 0 and this is an example of a special subspace called the null space. The system is consistent and has infinitely many solutions.
