The domains amortized expense be after one year is $27.80, the correct option is C

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given that;

The expenditure of sami= $250

Now,

To calculate the amortized expense of the domain name, we need to divide the total cost by the number of years before it needs to be renewed or sold. In this case, Sami spent $250 and has nine years before renewal, so the annual amortized expense will be:

$250 / 9 = $27.78

Rounding this to the nearest cent

Therefore, by algebra the answer will be $27.78.

The x-intercepts of R(x) are (-3,0), (1,0), and (-2,0), and the y-intercept is (0,-24).

To find the x-intercepts of R(x) = (2x+6)(x-1)(4-2)(x+2), we need to set R(x) equal to 0 and solve for x:
0 = (2x+6)(x-1)(4-2)(x+2)
This equation can be simplified to:
0 = (2x+6)(x-1)(2)(x+2)
We can use the zero product property to find the x-intercepts:
2x+6 = 0, x-1 = 0, 2 = 0, x+2 = 0
Solving for x, we get:
x = -3, x = 1, x = -2
So, the x-intercepts are (-3,0), (1,0), and (-2,0).
To find the y-intercepts, we need to set x equal to 0 and solve for R(x):
R(0) = (2(0)+6)(0-1)(4-2)(0+2)
R(0) = (6)(-1)(2)(2)
R(0) = -24
So, the y-intercept is (0,-24).

Therefore , the solution of the given problem of percentage comes out to be 38 years old is the median age.

In statistics, a "a%" is a figure or statistic that is expressed as a percentage of 100. The words "pct," "pct," but instead "pc" are also not frequently used. However, the sign "%" is frequently used to represent it. The percentage sum is flat; there are no dimensions. Percentages are truly integers because their numerator almost always equals 100. Either the % symbol (%) or the additional term "fraction" must come before a number to denote that it is a percentage.

Here,

The following algorithm must be used to determine the mean age:

=> mean = (all years added together) / (total number of persons)

The representative age for each age group is the age that falls in the middle of the range. With this approach, we can determine the total age as follows:

=>18(9) + 23(28) + 28(33) + 33(90) + 38(122) + 56(48) + 48(24) + 76(20) + 1089(0.25)

=> 162 + 644 + 924 + 2970 + 4636 + 2688 + 1152 + 1520 + 272.25

=>18(9) + 23(28) + 28(33) + 33(90) + 38(122) + 56(48) + 48(24) + 76(20) + 1089(0.25)

According to the information provided, there are 460 people in total.

=> mean = 17745.25 / 460

=> mean = 17745.25 / 460

As a result, the average lifespan is roughly 38.552 years.

The age category in this instance with the highest frequency has a midpoint of 38 and a frequency of 122. As a result, 38 years old is the median age.

The proportional equation for p in terms of s which matches the given context is p = 34s.

What is a proportional equation?

A proportional equation is written as y = kx. The equation's variables are the letters y and x. The proportionality constant, which never changes, is symbolised by the letter k.

We are given that a store buys 10 sweaters for $50 and sells them for $390.

Cost of one sweater = $50 / 10 = $5

Sale price of one sweater = $390 / 10 = $39

We know that total profit = Sale price - Cost price.

So, we get

p = 39s - 5s

p = 34s

Hence, the proportional equation for p in terms of s which matches the given context is p = 34s.

The distance between the x and y intercepts of that line is √13/2. The correct answer is (B).

To find the distance between the x and y intercepts of a line, we can use the distance formula:
d = √((x₂ - x₁)² + (y₂ - y₁)²)

First, we need to find the x and y intercepts of the line. The x intercept is where the line crosses the x-axis, so we can set y to 0 and solve for x. Similarly, the y intercept is where the line crosses the y-axis, so we can set x to 0 and solve for y.

Using the point-slope form of a line, we can find the equation of the line passing through the points (1,2) and (−0.5,1):
y - 1 = (1 - 2)/(−0.5 - 1)(x - (-0.5))
y - 1 = -2(x + 0.5)
y = -2x - 1

Now we can find the x and y intercepts:
For the x intercept, set y to 0:
0 = -2x - 1
2x = -1
x = -1/2

For the y intercept, set x to 0:
y = -2(0) - 1
y = -1

So the x intercept is (-1/2, 0) and the y intercept is (0, -1). Now we can use the distance formula to find the distance between these two points:
d = √((-1/2 - 0)² + (0 - (-1))²)
d = √((-1/2)² + (1)²)
d = √(1/4 + 1)
d = √(5/4)
d = √13/2

Therefore, the distance between the x and y intercepts of the line is √13/2.

The greatest common factor of 8m2 and 7b3 is the largest monomial that can divide both 8m2 and 7b3. So, the greatest common factor of 8m^(2) and 7b^(3) is 1.


The greatest common factor (GCF) of two monomials is the product of the greatest common factor of their coefficients and the greatest common factor of their variables. In this case, the greatest common factor of the coefficients is 1, since 8 and 7 have no common factors other than 1. The GCF of the variables is 1, since m and b have no common factors. Therefore, the GCF of 8m^(2) and 7b^(3) is 1*1 = 1.

Here is a step-by-step explanation:
1. Find the GCF of the coefficients: GCF(8,7) = 1
2. Find the GCF of the variables: GCF(m^(2),b^(3)) = 1

The given equation is z = 1 + iβ/β + 2i. We need to determine the value(s) for β such that the equation holds true.

First, we can multiply both sides of the equation by β + 2i to get rid of the denominator:

z(β + 2i) = 1 + iβ

Next, we can distribute the z on the left-hand side of the equation:

zβ + 2iz = 1 + iβ

Now we can rearrange the equation to get all the β terms on one side:

zβ - iβ = 1 - 2iz

We can factor out the β on the left-hand side:

β(z - i) = 1 - 2iz

Finally, we can divide both sides of the equation by z - i to get the value of β:

β = (1 - 2iz)/(z - i)

This is the value of β that satisfies the given equation. None of the given options match this value, so the correct answer is "None of the given options."

Answer: -sqrt(3)/4

Step-by-step explanation:

To solve this trigonometric expression, we can use the following trigonometric identities:

sin (180 + x) = -sin x

cos (180 + x) = -cos x

Using these identities, we can rewrite the expression as:

sin(200°)cos(80°) - cos(200°)sin(80°)

= sin(180° + 20°)cos(80°) - cos(180° + 20°)sin(80°)

= -sin(20°)cos(80°) + cos(20°)sin(80°)

= (cos(20°) - sin(20°))sin(80°)

= sin(70°)sin(80°)

= (cos(20°) - cos(150°))/2

= (-sqrt(3)/2 - sqrt(3)/2)/2

= -sqrt(3)/4

Therefore, sin(200°)cos(80°) - cos(200°)sin(80°) = -sqrt(3)/4.

What is system of linear equations?

A system of linear equations is a set of two or more equations with two or more variables that are to be solved simultaneously. Each equation in the system is linear, meaning it can be written in the form of ax + by + cz + ... = d, where a, b, c, and d are constants and x, y, z, and other variables are unknowns.

The goal of solving a system of linear equations is to find the values of the variables that satisfy all of the equations in the system. The solution of a system of linear equations is a set of values for the variables that make all of the equations true.

There are different methods to solve systems of linear equations, such as substitution method, elimination method, and matrix method. These methods involve manipulating the equations in the system to isolate one variable, substitute its value into another equation, and eventually find the values of all the variables.

Systems of linear equations are used in many areas of mathematics, science, engineering, and economics to model real-world situations and solve practical problems.

To find the solution to the set of equations, we need to determine the values of x and y that satisfy both equations simultaneously. One way to do this is to use substitution or elimination methods.

However, the given answer choices do not seem to be the steps of a solution process. We need to use both equations to find a solution. Here is one possible way to do it:

Equation S: y = x + 9

Equation T: y = 2x + 1

Since both equations equal to y, we can set them equal to each other:

x + 9 = 2x + 1

Simplifying this equation, we get:

x = 8

Now that we know the value of x, we can substitute it into either Equation S or Equation T to find the value of y. Let's use Equation S:

y = x + 9

y = 8 + 9

y = 17

Therefore, the solution to the set of equations is (x, y) = (8, 17).

None of the given answer choices matches this solution process.

Answer:

isosceles triangle.

Step-by-step explanation:

To classify triangle WXY by its sides, we need to determine whether all three sides are equal, two sides are equal, or all three sides are different. We can do this by calculating the lengths of the sides using the distance formula:

Side WX:

sqrt[(x2 - x1)^2 + (y2 - y1)^2] = sqrt[(-1 - 4)^2 + (-3 - (-10))^2] = sqrt[5^2 + 7^2] = sqrt(74)

Side WY:

sqrt[(x2 - x1)^2 + (y2 - y1)^2] = sqrt[(11 - 4)^2 + (-5 - (-10))^2] = sqrt[7^2 + 5^2] = sqrt(74)

Side XY:

sqrt[(x2 - x1)^2 + (y2 - y1)^2] = sqrt[(11 - (-1))^2 + (-5 - (-3))^2] = sqrt[12^2 + 2^2] = sqrt(148)

Since the lengths of sides WX and WY are equal, but the length of side XY is different, we can classify triangle WXY as an isosceles triangle. Specifically, it is an isosceles triangle with sides WX and WY equal.
