If the Set W Is a Vector Space, Find a Set

question 1

Multiple Choice

If the set W is a vector space, find a set S of vectors that spans it. Otherwise, state that W is not a vector space.
-Let $\mathrm { H }$ be the set of all points in the $\mathrm { xy }$ -plane having at least one nonzero coordinate: $\mathrm { H } = \left\{ \left[ \begin{array} { l } \mathrm { x } \\ \mathrm { y } \end{array} \right] : \mathrm { x } , \mathrm { y } \right.$ not both zero $\}$ . Determine whether $\mathrm { H }$ is a vector space. If it is not a vector space, determine which of the following properties it fails to satisfy:
A: Contains zero vector
B: Closed under vector addition
C: Closed under multiplication by scalars

• A) \(\mathrm { H }\) is not a vector space; not closed under vector addition
• B) \(\mathrm { H }\) is not a vector space; does not contain zero vector
• C) \(\mathrm { H }\) is not a vector space; fails to satisfy all three properties
• D) \(\mathrm { H }\) is not a vector space; does not contain zero vector and not closed under multiplication by scalars

Cumulative interest in goods and services within an economic structure, evaluated at a particular comprehensive price level over a specific duration.

Short Run

A timeframe in which a company has at least one input that remains constant and is unable to be altered.

Short-Run Equilibrium

A state in economics where demand equals supply, resulting in market stability over a temporary period.

Long-Run Aggregate-Supply Curve
