Suppose that v = (v1, v2, ..., vn) and û = (u₁, U2, ..., Un) are a pair of n-dimensional vectors. Assume that each component of the vector is a real number, so 7 and u are both members of the set R¹. We will say that and u are "almost the same" when every component of is close to every component of ū. That is, v₁ is close to u₁, v2 is close to u2, etc (practically speaking, "close" means that their absolute difference is small). Assume that we are given the predefined predicate CloseTo(x, y) and the integer constant n. Use them to write a formal definition of the new predicate Almost The Same (7, u) which asserts that n dimensional vector is almost the same as ū. Tip: It is not legal to say i v to refer to a component of v, because is not a set. Instead, use vi to refer to the ith component of v. What set would i belong to in this case?

Give a step by step proof with as much detail as possible.
Prove that in a given vector space V, the zero vector is unique. Suppose, by way of contradiction, that there are two distinct additive identities 0 and un. Which of the following statements are then true about the vectors 0 and u.? (Select all that apply ) O The vector 0 + u, is not equal to u, +0 O The vector 0 + u, does not exist in the vector space V. O The vector 0 + u, is not equal to 0. O The vector 0 + u, is equal to un O The vector 0 + u, is equal.to 0 O The vector 0 + u, is not equal to u,. Which of the following is a result of the true statements that were chosen and what contradiction then occurs? O The statement u, + 0 # 0, which contradicts that u, must have an additive inverse. O The statement u, + 0 + 0 + u, which contradicts the commutative property. O The statement u, = 0, which contradicts that there are two distinct additive identities. O The statement u, + 0 + 0, which contradicts that u, is an additive identity. The statement u, + 0 + u. which contradicts that 0…
