Answers
Answer:
Perimeter of triangle = 14.82 approx.
Step-by-step explanation:
Given:
D(5, 6)
E (10, 9)
F(7, 11)
Find:
Perimeter of triangle
Computation:
Distance = √(x1-x2)² + (y1-y2)²
Perimeter of triangle = DE + EF + FD
Perimeter of triangle = √(5-10)² + (6-9)² + √(10-7)² + (9-11)² + √(7-5)² + (11-6)²
Perimeter of triangle = √25 + 9 + √9 + 4 + √4 + 25
Perimeter of triangle = √34 + √13 + √29
Perimeter of triangle = 5.83 + 3.6 + 5.3851
Perimeter of triangle = 14.8151
Perimeter of triangle = 14.82 approx.

CNN reported in early 2018 that higher-income shoppers are the biggest bargain shoppers searching Amazon, clicking on their mobile devices and even querying Alexa looking for the best deals. If Rebecca Johnson purchased a state-of-the-art Biologique Recherche facial machine for her home business for $123,000, with a useful life of 4 years and a residual value of $42,500.
What would be the book value of the machine after the first year using the straight-line depreciation method?
Answers
To calculate the book value of the Biologique Recherche facial machine after the first year using the straight-line depreciation method, we can use the following formula:
Book Value = Cost - (Depreciation Expense * Number of Years Depreciated)
In this case, the cost of the machine is $123,000, the useful life is 4 years, and the residual value is $42,500. We can use these values to calculate the annual depreciation expense as follows:
Annual Depreciation Expense = (Cost - Residual Value) / Useful Life
= ($123,000 - $42,500) / 4
= $30,375
To calculate the book value of the machine after the first year, we can plug these values into the formula above:
Book Value = $123,000 - ($30,375 * 1)
= $123,000 - $30,375
= $92,625
Therefore, the book value of the Biologique Recherche facial machine after the first year using the straight-line depreciation method would be $92,625.
Answer:
$92,875
Step-by-step explanation:
To calculate the book value of the machine after the first year using the straight-line depreciation method, you would need to subtract the annual depreciation expense from the original cost of the machine. The annual depreciation expense is calculated by subtracting the residual value of the machine from the original cost and dividing that amount by the useful life of the machine in years.
In this case, the annual depreciation expense would be calculated as follows:
Annual depreciation expense = ($123,000 - $42,500) / 4 years = $30,125 per year
Therefore, the book value of the machine after the first year would be:
Book value = $123,000 - $30,125 = $92,875
This means that the machine would be recorded on Rebecca's balance sheet as having a value of $92,875 after the first year of use.

Answers
Given:
The function are:
\(f(x)=2x^3+5x^2-6x-7\)
\(g(x)=2x-3\)
To find:
The function (f-g)(x).
Solution:
We have,
\(f(x)=2x^3+5x^2-6x-7\)
\(g(x)=2x-3\)
We need find (f-g)(x).
\((f-g)(x)=f(x)-g(x)\)
\((f-g)(x)=2x^3+5x^2-6x-7-(2x-3)\)
\((f-g)(x)=2x^3+5x^2-6x-7-2x+3\)
On combining like terms, we get
\((f-g)(x)=2x^3+5x^2+(-6x-2x)+(-7+3)\)
\((f-g)(x)=2x^3+5x^2-8x-4\)

Your answers should be exact numerical values.
The mean of the data is
The median of the data is
The mode of the data is
The midrange of the data is
Answers
The Mean is 17, Median is 18, Mode is 18 and, Midrange is 17.
The Mean is defined as the ratio of sum of numbers present in the data to the total numbers present in the data. Median is defined as the ratio of sum of middle numbers present in the data. Mode is defined as the most recurring number present in the data. Midrange is the ratio of the largest and smallest number in the data to 2.
Let's see how to calculate Mean, Median, Mode and Midrange.
Mean = 13 + 15 + 18 + 18 + 21 / 5
Mean = 85 / 5
Mean = 17
Median = 18 (as it is the middle term of the data)
Mode = 18 (as it is most recurring number)
Midrange = 21 + 13 / 2
Midrange = 34 / 2
Midrange = 17
Therefore, The Mean is 17, Median is 18, Mode is 18 and, Midrange is 17.

A and 112 are opposite interior angles so they have to add up to 180.

What is 4 1/4 as a decimal number ?
Answers
Answer: It took me a long time to write this. Can i have brainliest if it is alright? =3
Step-by-step explanation: To start off, note that 4 1/4 is a mixed number, also known as a mixed fraction. It has a whole number and a fractional number. We have labeled the parts of the mixed number below so it is easier to follow along.
4 = Whole number
1 = Numerator
4 = Denominator
To get 4 1/4 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction.
Here are the detailed math steps we use to convert 4 1/4 mixed number to decimal form:
Step 1: Multiply the whole number by the denominator:
4 × 4 = 16
Step 2: Add the product you got in Step 1 to the numerator:
16 + 1 = 17
Step 3: Divide the sum from Step 2 by the denominator:
17 ÷ 4 = 4.25
That's it folks! The answer to 4 1/4 in decimal form is displayed below:
4 1/4 = 4.25

Answer: D
Step-by-step explanation:
The given expression is 2w3 + 7w2 - 4w.
The power of the expression is the highest exponent of the variable w, which is 3. However, this is not one of the options given.
A factor of the expression is a term or expression that divides the given expression completely. -4w is not a factor of the given expression.
The coefficient of a term is the numerical factor that is multiplied by the variable. The coefficient of the first term 2w3 is 2, and the coefficient of the second term 7w2 is 7. The coefficient of the last term -4w is -4. Therefore, the statement "The coefficient of the expression is w" is false.
The given expression has three terms: 2w3, 7w2, and -4w. Therefore, the statement "The expression has 3 terms" is true.

Ben is 9 years younger than his brother Jeff. in 10 years, the sum of their ages will be 67 how old are they now
Answers
Ten years later, Jeff would be x + 10 years old and Ben would be (x - 9) + 10 years old.
x + 10 + (x - 9) + 10 = 67

2x = 56
x = 28
Jeff is 28 right now and Ben is 19 right now.
Let Jeff's age = x and Ben's age = x - 9.
(x + 10) + (x -9 + 10) = 67
x + 10 + x + 1 = 67
2x + 11 = 67
2x = 56
x = 28
x - 9 = 28 - 9 = 19
Jeff is 28 years old, and Ben is 19 years old.
