Question 1 of 10

Archy [21]

Answer:

A. y = 7(x + 1)²-3

Step-by-step explanation:

Parabola:

$y = 7x^{2} + 14x + 4$

$y = 7(x^{2} + 2x) + 4$

Putting into vertex form, remember that:

$(x + a)^{2} = x^{2} + 2ax + a^{2}$

In this question:

$x^{2} + 2x$ , to put into this format:

$x^{2} + 2x + 1 = (x + 1)^{2}$

We add one inside the parenthesis to do this. The parenthesis is multiplied by 7, so for the equivalent, we also have to subtract 7. Then

Vertex form:

$y = 7(x^{2} + 2x + 1) + 4 - 7$

$y = 7(x + 1)^{2} - 3$

So the correct answer is:

A. y = 7(x + 1)²-3

At a football match, there were 250 more men than women. The number of children was twice the number of women and the number of

zlopas [31]

Answer:

450 people were at the match

Step-by-step explanation:

So let's make equation :

W = women

M = Men

C = Children

First equation :

M = W + 250

Second equation :

C = 2W

Third equation :

M = 2(W+C)

Let's substitute the second equation into the third :

M = 2(W + 2W)

M = 2W + 4W

M = 6W

Let's substitute this equation into the first one :

6W = W + 250

5W = 250

W = 50

Now we know that that there were 50 women at the match and can substitute this value for the first equation and then the second :

M = 50 + 250

M = 300

This means that there must have been 300 men at the match.

C = 2(50)

C = 100

This means that there must have been 100 children at the match.

Adding all values together gives us :

50 + 300 + 100 =

450 people were at the match

Hope this helped and have a good day

Calvin purchased a new office desk on July 23 2018 at a cost of 2373 he did not claim the bonus depreciation deduction using hal

earnstyle [38]

Calvin may claim 2018 depreciation in the amount of $339.

<u> Solution: </u>

The following are the given details,

Cost of the new desk = $2373
The recovery period of the new office desk is 7 years.

We have to find the amount that has to be claimed on 2018 depreciation

We know, the rate of MACRS(Modified Accelerated Cost Recovery System) depreciation is 14.29% (Using the half-year convention)

$\Rightarrow \$2373\times14.29\%=\$2373\times\frac{14.29}{100}=\$339$

Half-year convention is used to evaluate depreciation for tax purposes and denotes that the fixed assests will be considered to be in service for one-half of its first year, irrespective of actual purchase date.

The half-year convention in tax accounting, is generally used for federal income tax purposes. It influences the depreciation deduction computation in the fiscal year in which the property like machinery, plant, etc was placed into the service.
