3. In R4 , does the set {(1, 1, 1, 0,(1, 0, 0, 0),(0,
1, 0, 0),(0, 0, 1, 1)}, span R4? In other words, can you
write down any vector (a, b, c, d) ∈ R4 as a linear
combination of vectors in the given set ? Is the above set of
vectors linearly independent ?

What does it means for a set of vectors a1; a2; : : : ; ; an to
be linearly independent?
What is the span of the set?
This question is about linear algebra
Prove the follwing statements
Suppose that S is a linearly independent set of vectors in the
vector space V and let w be a vector of V that is
not in S. Then the set obtained from S by adding w
to S is linearly independent in V.
If U is a subspace of a vector space V and dim(U)=dim(V), then
U=V.
1: Let X be the set of all ordered
triples of 0’s and 1’s. Show that X consists of 8 elements
and that a metric d on X can be defined by

Let A be some m*n matrix. Consider the set S = {z : Az = 0}.
First show that this is a vector space. Now show that n = p+q where
p = rank(A) and q = dim(S). Here is how to do it. Let the vectors
x1, . . . , xp be such that Ax1, .
. . ,Axp form a basis of the column space of A (thus
each x can be chosen to be some unit...
Consider the set of integer numbers from 0 to 9, that is {0, 1,
2, 3, 4, 5, 6, 7, 8, 9}. Bob wishes to use these numbers to create
a 7-digit password to secure his new laptop. Note that each number
can appear in any position (for example, 0 can be the first number
in the password). (a) Find the number of 7-digit passwords that are
possible. (b) Find the number of 7-digit passwords with distinct
digits. (c) Find...
