Show that the set of vectors {(−4,1,3),(5,1,6),(6,0,2)} does not span R 3 , but that it does span the subspace of R 3 consisting of all vectors lying in the plane with equation x + 13y − 3z = 0.

Answers

Answer 1
Answer:

Answer:

The vectors does not span R3 and only span a subspace of R3 which satisfies x+13y-3z=0

Explanation:

The vectors are given as

Now if the vectors  would span the , the rank of  the consolidated matrix will be 3 if it is not 3 this indicates that the vectors does not span the .

So the matrix is given as

In order to calculate the rank, the matrix is reduced to the Row Echelon form as

As the Rank is given as number of non-zero rows in the Row echelon form which are 2 so the rank is 2.

Thus this indicates that the vectors does not span

Now for any vector the corresponding equation is formulated by using the combined matrix which is given as  for any arbitrary vector and the coordinate as

Now converting the combined matrix as

From this it is seen that whatever the values of the coordinates does not effect the value of the plane with equation as

So it is verified that the subspace of R3 such that it satisfies x+13y-3z=0 consists of all vectors.

On April 1, 2016, the KB Toy Company purchased equipment to be used in its manufacturing process. The equipment cost $57,200, has an ten-year useful life, and has no residual value. The company uses the straight-line depreciation method for all manufacturing equipment. On January 4, 2018, $14,750 was spent to repair the equipment and to add a feature that increased its operating efficiency. Of the total expenditure, $2,900 represented ordinary repairs and annual maintenance and $11,850 represented the cost of the new feature. In addition to increasing operating efficiency, the total useful life of the equipment was extended to 12 years.

Required:

1. Prepare journal entries for the depreciation for 2016 and 2017.
2. Prepare journal entries for the 2018 expenditure.
3. Prepare journal entries for the depreciation for 2018.

2018 Depreciation

Dr depreciation expense          $4800.83

Cr Accumulated depreciation                     $4800.83

Explanation:

There are two policies for depreciating non-current asset  especially when it is acquired part-way through the year like we have here, namely full year depreciation in the year of purchase and none in the year of disposal or proportional depreciation throughout the useful life,I am adopting the former in this question.

Formula for depreciation=cost-residual value/useful life

Yearly depreciation is ($57200-$0)/10=$5720

However,after two years the book value is calculated thus:

Book value=$57200-($5720*2)=$45760

additional cost incurred in enhancing the capacity of the asset would be added :  $45760 +$11,850=$57610

Since the useful life has also been reviewed up to 12 years, the depreciation from now on is $57610/12=$4800.83

A house was purchased for $350,000 in the year 2010. The value has been increasing by $7,000 per year. Write the function and find the value of the house after 5 years.

Answers

When the original purchase value of the house in the year 2010 was $350,000, and this value has been increasing by $7,000 per year, then the future value of the house after 5 years will be $385,000.

What is the significance of future value?

A future value can be referred to or considered as the value that a good or a commodity will have at the end of said number of periods, which is usually represented in terms of years. This future value is never based on assumptions.

For the above condition, the value increases by $7,000 every year, so after 5 years it would increase by 7000×5 = $35,000. Thus, the future value of the house will be computed as under,

Future Value = Original Value + Increase in Value

Future Value = 350,000 + 35,000

Future Value = $385,000.  

Therefore, the significance regarding a future value has been aforementioned.

Explanation:

In business strategy, first mover advantage (FMA) refers to the competitive advantage that a company can acquire by being the first company to enter a new market or market segment. In order for this first entrance to be considered an advantage, the company must gain some control of resources or hold a significant position in the market.

For example, Microsoft introduced its Surface tablets before Apple introduced the iPad but it never gained a significant position in the market, so it never had a FMA.
