In each of the following problems, decide whether the given subset W of the vector space V is or is not a subspace of V. If not, identify at least one requirement that is not satisfied. Assume that the standard definitions of addition and scalar multiplication hold.
(a) V = P2, W = {p(t) | degree of p(t) = 2}
(b) V = C[0,1], W = {f(t) | f(0) = f(1) = 0}
(c) V = C[a, b], W = {f(t) | lim(a→b)∫ f(t) dt = 0}
(d) V = C²[0,1], W= {f(t) | f" +2f = 4}

step-by-step explanation:

idk

what are the answer choices given for this problem?

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
