Answer: cage  I

Step-by-step explanation:

Given

43 gm of copper and 7 gram of other metal

Another cage has 83 gram of copper and 17 gm of other metals

Here, the percentage of copper is

For the first case

\Rightarrow \dfrac{43}{43+7}\times 100=86\%

For the second case

\Rightarrow \dfrac{83}{83+17}\times 100=83\%

So, the cage-I has more percentage of copper

The correct options for the linear combinations of the vectors are given by:

A, B, C, D, E and F.

<h3>What is a span between two vectors?</h3>

The span between two vectors is the set that contains all linear combinations between these two vectors.

Supposing we have two vectors u1 and u2, as is the case in this problem, the infinitely many linear combinations have the following format:

k1u1 + k2u2

In which k1 and k2 are real numbers.

With k1 = 4 and k2 = -7, we get that option A is correct.

For option B, the vector 0 will always be a part of the span, as it can be formed with constants 0, hence it is correct.

The dimension of the span is of 3, as the vectors have 3 elements, hence option C is correct.

The underlying vectors will always also be part of the span, as they can be formed with their constant 1 and the others at 0, hence options D and F are correct.

The size of the span of any vectors is of infinity, hence option E is correct while option G is not.
