An example of a linear function table is y=3x

A linear function is used to relate an independent variable and a dependent variable by introducing a rate of change(function) of which the independent variable is equated to find the dependent variable. Linear functions are those whose graph is a straight line. The following is the form of a linear function. a + bx = y = f(x). One independent variable and one dependent variable make up a linear function. X and Y are the independent and dependent variables, respectively.

for example:

y=3x hence is the dependent variable as it depends on the change of x and 3 is the rate of change which is a constant and is determined by the division of the values of y/x hence to make a table of y over x of which y is determined by the rate of change the unrelated variable x, 3.

Answer:

y = 3x - 5  

Step-by-step explanation:

1) First, place the given equation in slope-intercept form, represented by the formula \(y = mx +b\), to find the slope. Whatever \(m\) or the coefficient of x-term is will be the slope. Isolate y in the equation:

\(x + 3y = -6\\3y = -x -6\\y = -\frac{1}{3}x-2\)

So, the slope of that line is \(-\frac{1}{3}\). Lines that are perpendicular have slopes that are opposite reciprocals, thus the slope of the new line will be 3.

2) Now, use the point-slope formula \(y-y_1 = m (x-x_1)\) to find the equation of the new line. Substitute real values for the \(m\), \(x_1\) and \(y_1\) in the equation.

Since \(m\) represents the slope, substitute \(-\frac{1}{3}\) in its place. Since \(x_1\) and \(y_1\) represents the x and y values of one point the line passes through, substitute the x and y values of (-1,-8) into the formula as well. Then, isolate the y in the resulting equation to put the equation in slope-intercept form and find an answer:

\(y-(-8) = 3 (x-(-1))\\y + 8 = 3(x+1)\\y + 8=3x + 3\\y = 3x -5\)

The expression for the power delivered to a resistance in terms of csc^2 2 pi ft is P = I^2_0 R (csc^2 2 pi ft).

According to the given information, the power delivered to a resistance R when an alternating current of frequency f and peak current I_0 passes through it is represented by the equation P = I^2_0 R sin^2 2 pi ft.

To express this equation in terms of csc^2 2 pi ft, we can use the trigonometric identity csc^2 x = 1/sin^2 x. Substituting this identity into the equation, we get P = I^2_0 R (1/sin^2 2 pi ft).

Since csc^2 x is the reciprocal of sin^2 x, we can rewrite the equation as P = I^2_0 R (csc^2 2 pi ft). This expression represents the power delivered to the resistance in terms of csc^2 2 pi ft.

Therefore, the correct expression for the power delivered to the resistance in terms of csc^2 2 pi ft is P = I^2_0 R (csc^2 2 pi ft).

The magnitude of the electric field at (0, 0, 3 m) is equal to the magnitude of the electric field at (0, 0, 1 m).

To determine the magnitude of the electric field at the given points, we can use the principle of superposition. The electric field at a point due to multiple charges is the vector sum of the electric fields produced by each individual charge.

Let's consider the three sheets of charge separately:

1. Infinite sheet with charge density +2 C/m² (located at the xy-plane):

Since this sheet is symmetric with respect to the origin and passes through it, the electric field it produces at the point (0, 0, z) will be directed along the z-axis. The magnitude of the electric field at (0, 0, z) due to this sheet can be calculated using Gauss's law and is given by:

E₁ = σ / (2ε₀),

where σ is the charge density (+2 C/m²) and ε₀ is the permittivity of free space.

2. Infinite sheet with charge density -1 C/m² (located at z = -2 m):

The electric field produced by this sheet at the point (0, 0, z) can be obtained in a similar manner. However, since this sheet is parallel to the xy-plane, the electric field it produces will be directed along the negative z-axis. The magnitude of the electric field at (0, 0, z) due to this sheet is:

E₂ = -σ / (2ε₀),

where σ is the charge density (-1 C/m²).

3. Infinite sheet with charge density -1 C/m² (located at z = +2 m):

This sheet also produces an electric field directed along the positive z-axis. The magnitude of the electric field at (0, 0, z) due to this sheet is the same as E₂:

E₃ = -σ / (2ε₀).

Now, let's compare the magnitude of the electric field at (0, 0, 3 m) to the magnitude of the electric field at (0, 0, 1 m):

At (0, 0, 3 m):

The total electric field E_total at this point is the sum of the electric fields produced by each sheet:

E_total = E₁ + E₂ + E₃ = σ / (2ε₀) - σ / (2ε₀) - σ / (2ε₀) = 0.

At (0, 0, 1 m):

The total electric field E_total at this point is:

E_total = E₁ + E₂ + E₃ = σ / (2ε₀) - σ / (2ε₀) - σ / (2ε₀) = 0.

Therefore, the magnitude of the electric field at (0, 0, 3 m) is equal to the magnitude of the electric field at (0, 0, 1 m).

Based on this analysis, none of the given options accurately describes the relationship between the electric fields at the specified points.

Answer:The sample mean used when computing the interval is 931.0 Dhs.

Step-by-step explanation:

In a confidence interval, the range of values is constructed around a point estimate, which is the sample mean in this case. The confidence interval provides an estimate of the population parameter, which is the mean claim payment.

In this scenario, Oman Insurance company took a random sample of 71 insurance claims paid out during a 1-year period. The resulting 95% confidence interval for the mean claim payment was (540 Dhs, 1,322 Dhs).

The midpoint of the confidence interval represents the sample mean. To find it, we take the average of the lower and upper bounds of the interval:

Sample Mean = (Lower Bound + Upper Bound) / 2

Sample Mean = (540 + 1,322) / 2

Sample Mean = 1,862 / 2

(a) Probability that both numbers are odd = 0.4932

(b) Probability that both numbers are less than 12 = 0.4545

(c) Probability that the same number is chosen twice = 1/60

(a) To find the probability that both numbers are odd, we need to count the number of ways to choose two odd numbers between 1 and 60, and divide by the total number of possible outcomes.

There are 30 odd numbers between 1 and 60, so there are 30 choices for the first number and 29 choices for the second number (since the two numbers can be the same). The total number of possible outcomes is 60 choose 2, which is

60 choose 2 = (60 × 59) / 2 = 1770

So the probability that both numbers are odd is

(30 × 29) / 1770 = 0.4932

(b) To find the probability that both numbers are less than 12, we need to count the number of ways to choose two numbers between 1 and 11, and divide by the total number of possible outcomes.

There are 11 choices for each number, so there are 11 × 11 = 121 possible outcomes. The number of ways to choose two numbers less than 12 is

11 choose 2 = (11 × 10) / 2 = 55

So the probability that both numbers are less than 12 is

55 / 121 = 0.4545

(c) To find the probability that the same number is chosen twice, we need to count the number of ways to choose a number, and then multiply by the probability that the same number is chosen again.

There are 60 choices for the first number, and only 1 choice for the second number if we want it to be the same as the first. So the probability that the same number is chosen twice is

1/60

So the probability that the same number is chosen twice is

(1/60) × 60 = 1/60

Step-by-step explanation:

The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.

The image of (-6, -1) over x axis is (-6, 1)

By graphing y=f(-x), we may reflect the graph of any function f about the x-axis, and by graphing y=f (-x), we can reflect the graph about the y-axis

Given:

As, The x-coordinate remains constant when a point is reflected across the x-axis, but the y-coordinate is assumed to be the additive inverse. Point (x, y) is reflected across the x-axis as (x, -y).

So, The rule for reflecting over the x axis is to negate the value of the y-coordinate of each point and leaving the x-value the same.

Hence, the image of (-6, -1) over x axis is (-6, 1)

According to the given rule of dilation, D subscript Q, two-thirds, the triangle ABC will be dilated with a scale factor of two-thirds centered at point Q.

Since point Q is the center of dilation and the distance from triangle ABC to point Q is 6 units, the image of vertex A will be 2/3 times the distance from A to Q. Therefore, the distance from A' (image of A) to Q will be (2/3) x 6 = 4 units.

f(0.5) = 4 [0.5] = 4 x 0 = 0

f(x) = 0 for 0 ≤ x < 1

f(1) = 4 [1] = 4

f(1.5) = 4 [1.5] = 4 x 1 = 4
