solving the inequality

Inequalities of the type | x | < a always have a solution of the form

- a < x < a

For | 2x - 6 | < 4  then solution is

- 4 < 2x - 6 < 4 ( add 6 to all 3  intervals )

2 < 2x < 10 ( divide all 3 intervals by 2 )

Answer:

1,000,000 / 1.03 = 970,873.79 After 1st Year

970,873.79 / 1.03 = 942,595.91 After 2nd Year

Step-by-step explanation:

Answer:

Two thirds rounded would be 66.67%. I’m uncertain whether you were asking about a straight line depreciation or some sort of degressive depreciation.

Basically, in a straight-line depreciation, you would calculate each depreciation as a fraction of your asset’s original value. A machine worth $1000 in year 0 would depreciate annually with a constant amount of $100.

Your machine would be worth less than 66.67% of its original value after at least 4 years (4 x 10%). More precisely, 3 years and (33.3% x 365 days) 122 days.

Applying a degressive depreciation method, you would calculate the depreciation in each year as a fraction of your asset’s residual value. This implies your depreciations would decrease each year (hence “degressive”). As soon as your depreciations fall below the amount you would depreciate in a straight line depreciation, you switch to the latter. The reason for this is that it does not really make sense for a company to depreciate it’s assets with a lesser amount, given the tax benefits of depreciations and the time value of money.

Assuming the duration of the asset’s useful life is 10 years, you would switch to the straight-line depreciations after the first year. This scenario would be equal to the straight-line depreciation: 3 years and 122 days.

In case the duration of the asset’s useful life is shorter or longer than 10 years, the amount of time required for the asset to have less than two-thirds of its initial value depends on the duration of is life.

so basically the answer is

1,000,000 / 1.03 = 970,873.79 After 1st Year

970,873.79 / 1.03 = 942,595.91 After 2nd Year

Answer:

48,000. Look at the tens place, If the number is 5 or higher then you round up, if its 4 or lower the hundreds place stays the same. Since the number in the tens place is higher than 4 you round up, meaning you would add 1 to 9 which give you ten. You would carry that ten over, giving you 48,000

The correct answer is 48,000.

To round the number 47,963 to the nearest hundreds:

Identify the digit in the tens place, which is 6.

Since the digit in the tens place is greater than or equal to 5, round up the hundreds place.

The current digit in the hundreds place is 9.

Rounding up the hundreds place from 9 results in increasing it to the next number, which is 10.

When the hundreds place increases to 10, it affects the thousands place as well:

The 7 in the thousands place becomes 8, because adding 1 to 9 in hundreds place essentially adds 1,000 to the overall number.

Set all digits to the right of the hundreds place to zero.

Thus, 47,963 rounded to the nearest hundreds becomes 48,000.

This process ensures accurate rounding based on standard rounding rules.

Hoped I helped <3

Step-by-step explanation:

We can multiply 336 by 2/3 to find out.

2/3(336)

To make this easier, we can change 336 to 336/1, which does not change it's value.

Multiply 336 by 2.

336 * 2 = 672

Multiply 1 by 3.

1 * 3 = 3

Our new value is 672/3

Evaluate, divide both sides of the fraction by 3.

672/3 = 224.

3/3 = 1

224/1

224/1 = 224

Answer:

A = $6567.29

Step-by-step explanation:

A = P(1+r)^t

Where A = amount in account

P = principal

r = interest rate in decimal form

t= time

We know that P =5500

r = .03

t =6

Substitute these values into the equation.

A = 5500(1+.03)^6

A = 5500(1.03)^6

A = 5500(1.194052297)

A=6567.287631

Since this is money we round to the nearest cent

A = $6567.29

-Charlie

The equation of the line for the given case is obtained as y = -1/2x - 2.

A straight line can be written in the slope-intercept form as, y = mx + c.

In order to obtain the slope, the ratio of the difference of the coordinates are taken and c is the y-intercept which can be found by substituting x = 0 in the equation.

The slope and y-intercept are given as -1/2 and -2 respectively.

The general form of the slope-intercept equation is y = mx + c.

Substitute m = -1/2 and c = -2 in the above equation to get,

y = -1/2x + (-2)

⇒ y = -1/2x - 2

Hence, the equation of line is given as y = -1/2x - 2.

Answer:

(x - 5i)(x + 5i)

Step-by-step explanation:

Find the roots by solving x² + 25 = 0

hence x² = - 25 ( take the square root of both sides )

x = ± 5i

x² + 25 = (x - 5i)(x + 5i)

width = perimeter/2 - length

w = 74/2 - 5 = 32

32/4 = 8 - 3 = 5

The length of the rectangle is 5.

The width of the triangle is 32

As per the given values, the length of the rectangle is 29 meters and the width is 8 meters.

To find the length and width of the rectangle, we can use the information given: the length is 3 meters less than four times the width, and the perimeter is 74 meters. Let's assume the width is 'w' meters. So, the length would be '4w - 3' meters. The perimeter of a rectangle is found by adding the lengths of all its sides, which in this case is twice the length plus twice the width.

We can set up an equation to solve for 'w': 2(4w - 3) + 2w = 74. Solving this equation will give us the width of the rectangle, and we can substitute that value back to find the length.

Step 1: Set up the equation:

2(4w - 3) + 2w

= 74.

Step 2: Simplify the equation:

8w - 6 + 2w

= 74.

Step 3: Simplify further:

10w - 6 = 74.

Add 6 to both sides.

Step 4: Continue to simplify:

10w = 80.

Divide both sides by 10.

Step 5: Solve for 'w':

w = 8.

The width of the rectangle is 8 meters.

Step 6: Find the length

= 4w - 3

= 4(8) - 3 = 32 - 3

= 29 meters.

Answer:

The 52nd term is -125

Step-by-step explanation:

The formula for an arithmetic sequence is

an = a1+d(n-1)

where a1 is the first term and d is the common difference.

a1 = 28

d = 25-28 = -3

Let's check  19-22 = -3  so the common difference is correct

an = 28 - 3(n-1)

We want to find the 52 term  so n = 52

a52 = 28 -3 (52-1)

a52 = 28 -3(51)

a52 = 28 -153

a52 = -125

Answer:

The correct answer option is dependent.

Step-by-step explanation:

We are given the following two equations and we are to determine whether these are independent, dependent or inconsistent:

[tex]y = 3x + 6[/tex] --- (1)

[tex]6x - 2y = -12[/tex] --- (2)

To compare these equations with each other, it is a good idea to write them in the same format with y being the subject. So rearranging equation (2) to get:

6x - 2y = -12

6x + 12 = 2y

2y = 6x + 12

y = 3x + 6

A system of equations is said to be dependent when the same line is written in two different forms so that there are infinite solutions.

Hence, this system of equations is dependent having infinite solutions.

The system of equations are classified as independent

To classify the system of equations as independent, dependent, or inconsistent, we can analyze their coefficients.

The given system of equations is:

y = 3x + 6

6x - 2y = -12

Comparing the coefficients, we can see that the slopes of the equations are equal (-2/-6 )

Reduce the fraction to smaller forms, we get;

1/3

Now, since the slopes are different, the system is consistent and has a unique solution, indicating an independent system.

Thus, the equations are independent.

Let use synthetic division

First we write all the coefficients of x^3 - 5x^2 + 4x + 7 inside

we need to divide by x-1. x-1=0 so x= 1

so we put 1 outside

The coefficients of x^3 - 5x^2 + 4x + 7  is 1, -5, 4, 7

    1                       1            -5           4            7

                                            1             -4         0
