You have to find the equation of a line that is parallel to the line:

And passes through the point (0,4)

Two lines that are parallel have the same slope, in this exercise, in the equation of the line parallel to the one we have to determine we can see that the x-term is "alone". The slope of the line is the coefficient that multiplies the x-term, this value is not written, but the x-term is, in reality, being multiplied by "1", which represents the slope of the line.

So, the slope of the line we are looking for is m=1

Now that we know the slope of the line, using the point-slope form, you can determine the equation of the line:

Where

m represents the slope of the line

(x₁,y₁) represents one point of the line

Replace the expression with m=1 and (x₁,y₁)=(0,4)

Pass "-4" to the right side of the expression by applying the opposite operation to both sides of the equal sign:

The equation of the line, that is parallel to y=x-2 and passes through the point (0,4) is:

Answer:

What is the value of 4p − 2 when P 8?

the answer is 30.

Step-by-step explanation:

Answer:

The answer is most likely A.

The reason why, is because since the earning in 6 hours is $94.50, so the hourly wage would be, $15.75 because:

94.50/6 = 15.75

Graph B, for the first hour, the amount of dollars is correct, but in 11 hours, it says 25.75, which is not correct so Graph B cannot be it.

Graph C, shows that at hour 1, that it is 15.75 dollars, but at hour 2 16.75, as well with hour 3, 17.75. The graph is showing an increase of 1 dollar per hour, which is not correct so graph C is not it.

Graph D shows that at hour 6, there is $94.50, which is correct, but at hour 12, its 100.50. This is not true because , the hour has increased by 6, and when it increased by 6, the amount of pay increased by 6 as well, which is not the right way in which you would do so.

Option A is correct!

The arc length of the curve is 4 units.

What is the arc length of a curve?

The arc length of a curve is the distance along the curve between two points. More specifically, it is the length of the curve segment that connects the two points, as measured by a straight line. In other words, it is the length of the curve that is "covered" when moving from one point to another along the curve.

The formula for finding the arc length of a curve in two or three dimensions involves integrating the magnitude of the derivative of the curve with respect to a parameter that describes the curve. In two dimensions, this parameter is typically denoted by t, while in three dimensions it is often denoted by s. The formula is:

L = ∫_aᵇ ∥r'(t)∥ dt

where r(t) = <x(t), y(t)> or r(t) = <x(t), y(t), z(t)> is the equation of the curve, r'(t) is its derivative with respect to t, and ∥ ∥ denotes the magnitude of a vector. The integral is evaluated from the starting value a to the ending value b of the parameter t or s.

Finding the arc length of a curve is an important problem in mathematics, and has many applications in physics, engineering, and other fields where the length of a curve needs to be calculated.

The given equation represents a curve in 3D space, defined by the function r(t) = <4√2,>, where 0 ≤ t ≤ 1. The missing coordinate indicates that the curve lies in a plane perpendicular to the z-axis, and therefore we can treat the problem as a 2D curve in the xy-plane.

To find the arclength of the curve, we use the formula:

L = ∫_aᵇ ∥r'(t)∥ dt

where r'(t) is the derivative of r(t) with respect to t, and ∥ ∥ denotes the magnitude of a vector.

The derivative of r(t) is:

r'(t) = <0, 4, 0>

and the magnitude of r'(t) is:

∥r'(t)∥ = √(0² + 4²+ 0²) = 4

Therefore, the arclength of the curve is:

L = ∫_0¹ 4 dt = 4t |_0¹ = 4

So the arclength of the curve is 4 units.

Relative interest refers to the comparison of interest rates between different financial instruments or investment opportunities. It allows individuals or investors to assess and evaluate the attractiveness of various options based on their potential returns.

1. Understand the basic concept: Interest is the cost of borrowing money or the return earned on invested funds. Relative interest involves comparing the interest rates of different financial instruments or investments to determine which one offers a more favorable return.

2. Identify the investment options: Start by identifying the different investment opportunities or financial instruments available. These can include savings accounts, certificates of deposit (CDs), bonds, stocks, or other investment vehicles.

3. Research interest rates: Research and gather information about the current interest rates offered by each investment option. This information can usually be found on financial websites, through financial institutions, or by consulting with a financial advisor.

4. Compare interest rates: Once you have the interest rates for each investment option, compare them side by side. Look for the differences in rates and identify which options offer higher or lower returns.

5. Assess risk and return: Consider the level of risk associated with each investment option. Higher returns often come with higher risk, so it's essential to evaluate the risk-reward tradeoff.

6. Make an informed decision: Based on the comparison of interest rates and the risk-reward assessment, make an informed decision on which investment option aligns with your financial goals and risk tolerance.

Always remember to consider your financial goals, risk tolerance, and consult with a financial advisor if needed.

Answer:

Where is the problem??

Step-by-step explanation:

Using the system of equation and determinant given, the value of k is any real number except -1/3

The determinant is a scalar value that can be computed from the elements of a square matrix. It is a useful tool in linear algebra and is used in many applications, including solving systems of linear equations, finding the inverse of a matrix, and calculating the volume of a parallelepiped.

Given the system of equations 3x + y + 2 = 0, -4x + 2y = k and 3x - y - 3k = 0.

We can write these equations in matrix form as AX = B, where A is the coefficient matrix, X is the variable matrix and B is the constant matrix.

A = [3 1 2]

[-4 2 k]

[3 -1 -3k]

X = [x]

[y]

[k]

B = [0]

[0]

[0]

To find the value of k for which the system is consistent, we need to find the determinant of the coefficient matrix.

|A| = (3)(2k) - (1)(-4) + (2)(3) = 6k + 2

For the system of equations to be consistent, the determinant of the coefficient matrix should not be equal to zero.

So, |A| = 6k + 2 ≠ 0

Therefore, the value of k can be any real number except -1/3.

So, the value of k can be any real number except -1/3. The system of equations is consistent for all real numbers except -1/3.

Answer:

The standard error of your estimate of the average height in the city is 0.5 inches.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \(\mu\) and standard deviation \(\sigma\), the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

You begin by collecting the heights of a random sample of 196 people from the city.

This means that \(n = 196\)

The standard deviation of the heights in your sample is 7 inches.

This means that \(\sigma = 7\)

The standard error of your estimate of the average height in the city is

\(s = \frac{\sigma}{\sqrt{n}} = \frac{7}{\sqrt{196}} = 0.5\)

The standard error of your estimate of the average height in the city is 0.5 inches.

The expression simplifies to |2x| = -2x, when x<0 by definition of absolute value

If x<0, then the expression |2x| simplifies to -2x.

The absolute value of a number is the distance of the number from zero on the number line.

Since x is negative in this case, 2x will be negative as well.

Taking the absolute value of -2x will give us the opposite of -2x, which is 2x.

However, since we know that x<0, this means that -2x will always be a positive number.

Hence, the expression simplifies to |2x| = -2x, when x<0.

Answer:

-80

Step-by-step explanation:

To find x, set the equation equal to zero

4x-20=0

the next step is to isolate the variable, you can do this by adding 20 to both sides, remember when you change one side of the equal sign you must do the same to both

4x=20

now you can divide by 4 to get x by itself, again divide both sides of the equation

4x/4=20/4

x=5

After doing the division we see that x is equal to 5, and you can always check to see if your answer is correct by plugging it back into the equation:

4(5)-20=0

20-20=0

Answer:

  x -y = -5

  3x +y = -11

Step-by-step explanation:

We assume you want two linear equations. Since you know a point on each line, the only thing you need to choose is the slope of the two lines through that point. We can make the slopes be +1 and -3, for example. Then the point-slope equations are ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

 y -1 = +1(x +4)

  y -1 = -3(x +4)

We can use these equations "as is", or put them in whatever form you like. I personally prefer "standard form:" ax+by=c.

First equation:

  y -1 = x +4 . . . . . . eliminate parentheses

  -5 = x -y . . . . . . . keep positive x term, put x and y together, separate from the constant

  x - y = -5 . . . . . . standard form

Second equation:

  y -1 = -3x -12 . . . . eliminate parentheses

  3x +y = -11 . . . . . . add 3x+1 to both sides
