The function f(x) = x - 2 has a domain of all real numbers and a range of all real numbers. Its inverse function, f^(-1)(x), also has a domain and range of all real numbers.
The domain of a function represents the set of all possible input values for the function. In the case of f(x) = x - 2, since there are no restrictions or limitations on the input variable x, the domain is all real numbers.
To find the range of the function, we consider the possible output values. The function f(x) = x - 2 is a linear function with a slope of 1. It means that for any input value of x, the output value will be that input value minus 2. Therefore, the range is also all real numbers.
To find the inverse function, we swap the roles of the input and output variables and solve for the new output variable. For the given function, we have f(x) = x - 2. Replacing f(x) with y, we get the equation y = x - 2. To find the inverse, we isolate x:
x = y + 2
Now, we replace x with the inverse function notation f^(-1)(x) and y with x:
f^(-1)(x) = x + 2
The inverse function has the same domain and range as the original function, which is all real numbers.

three line segments have measures of 4 units, 6 units, and 8 units. Will the segments form a triangle?
Given:
Three line segments have measures of 4 units, 6 units, and 8 units.
To find:
Will the segments form a triangle?
Solution:
We know that three line segments can form a triangle if the sum of two smaller sides is greater than the largest side.
Three line segments have measures of 4 units, 6 units, and 8 units. Here, the measure of the largest sides is 8 units.
The sum of two smaller sides is
[tex]4+6=10[/tex]
[tex]4+6>8[/tex]
Since the sum of two smaller sides is greater than the largest side, therefore the segments will form a triangle.

By filling in the elements accordingly and comparing the Venn diagram with the calculated results, the accuracy of the union and intersection can be confirmed i.e. AUB = {1, 2, 3, 4, 5, 6, 7, 8, 9} and An B = {4, 8}.
To find the union (AUB) and intersection (An B) of the sets A = {1, 4, 6, 8, 9} and B = {2, 3, 4, 5, 7, 8}, we compare the elements in the sets. The union (AUB) is the combination of all unique elements from both sets, while the intersection (An B) consists of the elements common to both sets.
(a) The union (AUB) is {1, 2, 3, 4, 5, 6, 7, 8, 9}, which includes all the distinct elements present in both sets.
(b) The intersection (An B) is {4, 8}, representing the elements that are common to both sets A and B.
To verify these results, you can draw a Venn diagram. Draw two overlapping circles representing sets A and B, and fill in the elements accordingly. The overlapping region represents the intersection, and the combination of all elements in both circles represents the union. Comparing the Venn diagram with the calculated results confirms the accuracy of the union and intersection.

Step-by-step explanation:
Calculate the flux of the vector field F (x,y, z) = 6i - 7k through a sphere of radius 5 centered at the origin, oriented outward. Fhux Calculate the flux of the vector field F (x,y, z) = i - 3j + 9K through a cube of side length 5 with sides parallel to the axes: oriented outward.
To calculate the flux of a vector field through a surface, we can use the surface integral of the dot product between the vector field and the outward-pointing normal vector of the surface.
Let's first calculate the flux of the vector field F = 6i - 7k through a sphere of radius 5 centered at the origin, oriented outward.
The equation of the sphere centered at the origin is [tex]x^2 + y^2 + z^2 = 5^2.[/tex]
To find the outward-pointing normal vector at each point on the sphere's surface, we normalize the position vector (x, y, z) by dividing it by the magnitude of the vector.
The outward-pointing normal vector is given by N = (x, y, z) / [tex]\sqrt{(x^2 + y^2 + z^2).}[/tex]
Now, we calculate the flux using the surface integral:
Flux = ∬S F · dS,
where S is the surface of the sphere.
The dot product F · dS can be expanded as F · N dS, where dS represents the differential area vector.
The magnitude of the differential area vector on the sphere's surface is given by dS = [tex]r^2[/tex]sin(θ) dθ dφ, where r is the radius of the sphere, and θ and φ are the spherical coordinates.
Since the sphere is symmetric about the origin, the flux will be the same for all points on the surface, and we can simplify the integral as:
Flux = F · N ∬S dS.
To find the flux, we need to calculate the dot product F · N and evaluate the surface integral over the sphere's surface. Let's calculate it:
F = 6i - 7k
N = (x, y, z) /[tex]\sqrt{(x^2 + y^2 + z^2)}[/tex] = (x, y, z) / 5
F · N = (6i - 7k) · (x/5, y/5, z/5) = (6x/5) - (7z/5)
Now, let's evaluate the surface integral over the sphere's surface:
Flux = ∬S F · dS = ∬S (6x/5 - 7z/5) dS
To evaluate the integral, we can use spherical coordinates. The limits of integration will be:
θ: 0 to 2π (complete rotation around the z-axis)
φ: 0 to π (from the positive z-axis to the negative z-axis)
Flux = ∫(φ=0 to π) ∫(θ=0 to 2π) (6r sin(φ) cos(θ)/5 - 7r sin(φ) sin(θ)/5) [tex]r^2[/tex]sin(φ) dθ dφ
Simplifying and evaluating the integral will give you the flux of the vector field through the sphere.
Now, let's move on to calculating the flux of the vector field F = i - 3j + 9k through a cube of side length 5 with sides parallel to the axes, oriented outward.
Since the sides of the cube are parallel to the coordinate axes, the normal vector to each side will be aligned with the corresponding unit vector.
For example, the normal vector to the side with a normal vector i will be (1, 0, 0), and the normal vector to the side with a normal vector j will be (0, 1, 0), and so on.
To calculate the flux, we need to find the dot product between the vector field F and the outward-pointing normal vectors of each side, and then sum up the flux for all six sides of the cube.
Let's calculate the flux for each side of the cube and then sum them up to get the total flux.
Side 1: Outward normal vector = (1, 0, 0)
Dot product = (i - 3j + 9k) · (1, 0, 0) = 1
Side 2: Outward normal vector = (-1, 0, 0)
Dot product = (i - 3j + 9k) · (-1, 0, 0) = -1
Side 3: Outward normal vector = (0, 1, 0)
Dot product = (i - 3j + 9k) · (0, 1, 0) = -3
Side 4: Outward normal vector = (0, -1, 0)
Dot product = (i - 3j + 9k) · (0, -1, 0) = 3
Side 5: Outward normal vector = (0, 0, 1)
Dot product = (i - 3j + 9k) · (0, 0, 1) = 9
Side 6: Outward normal vector = (0, 0, -1)
Dot product = (i - 3j + 9k) · (0, 0, -1) = -9
Now, sum up all the dot products to get the total flux:
Flux = 1 + (-1) + (-3) + 3 + 9 + (-9) = 0
The total flux of the vector field through the cube is zero.

Damien receives an annual salary of $55,300; he is paid weekly, and his regular workweek is 39.5 hours. a) Calculate his regular pay per payment period. b) Calculate his hourly rate of pay. $ c) If his overtime rate is double the regular pay, calculate the overtime rate of pay. d) What is Damien's gross pay for a pay period in which he worked 8 hours overtime at double regular pay?
Damien's regular pay per payment period is $1,062.50, his hourly rate of pay is $26.87, his overtime rate of pay is $53.74, and his gross pay for a pay period in which he worked 8 hours overtime is $1,492.42.
a) Calculation of Damien's regular pay per payment period: Given, Damien receives an annual salary of $55,300.Damien is paid weekly and his regular workweek is 39.5 hours. Therefore, the regular pay per payment period = 55,300/52 = $1,062.50So, Damien's regular pay per payment period is $1,062.50.
b) Calculation of Damien's hourly rate of pay: Let's calculate the hourly rate of pay for Damien, we will divide the regular pay per payment period by the regular workweek hours. Hourly rate of pay = 1,062.50/39.5 = $26.87Thus, Damien's hourly rate of pay is $26.87.
c) Calculation of Damien's overtime rate of pay: The overtime rate of pay will be double the hourly rate of pay. Hence, Damien's overtime rate of pay will be: Double the hourly rate of pay = 2 × 26.87 = $53.74. Therefore, Damien's overtime rate of pay is $53.74.
d) Calculation of Damien's gross pay for a pay period in which he worked 8 hours overtime at double regular pay: Damien worked 8 hours overtime, so his gross pay for the pay period will be: Regular pay = 39.5 hours × $26.87 per hour = $1,062.50. Overtime pay = 8 hours × $53.74 per hour = $429.92Gross pay = Regular pay + Overtime pay= 1,062.50 + 429.92= $1,492.42Therefore, Damien's gross pay for a pay period in which he worked 8 hours overtime at double the regular pay is $1,492.42.

Find the metal solution to the linear system of differential equations 937 (b) (2 points) Give a physical description of what the solution curves to this linear system look like. What happens to the solution curves as to 12?
The solution to the system of equations is[tex]X(t) = c_1 * e^{6t} * [37 \ \ -3] + c_2 * e^{-3t} * [-37\ \ 12][/tex]. The solution curves exhibit a combination of exponential growth and decay, and as t approaches infinity, they converge towards the eigenvector associated with the negative eigenvalue.
To find the general solution to the linear system of differential equations:
[tex]X' = \left[\begin{array}{ccc}9&37\\-1&-3\end{array}\right] X[/tex]
We need to find the eigenvalues and eigenvectors of the coefficient matrix [[9 37] [-1 -3]].
Let A be the coefficient matrix.
The characteristic equation is given by:
det(A - λI) = 0, where λ is the eigenvalue and I is the identity matrix.
The coefficient matrix A - λI is:
[tex]X' = \left[\begin{array}{ccc}9-\lambda&37\\-1&-3-\lambda\end{array}\right] X[/tex]
Setting the determinant equal to zero:
[tex]det (\left[\begin{array}{ccc}9-\lambda&37\\-1&-3-\lambda\end{array}\right] )[/tex]
Expanding the determinant, we get:
[tex](9-\lambda)(-3-\lambda) - (-1)(37) = 0[/tex]
Simplifying the equation, we have:
[tex](\lambda-6)(\lambda+3) = 0[/tex]
Solving for λ, we find two eigenvalues:
[tex]\lambda_1 = 6\\\lambda_2 = -3[/tex]
Next, we find the eigenvectors corresponding to each eigenvalue.
For [tex]\lambda_1 = 6[/tex]:
[tex](A - \lambda_1I)v_1 = 0[/tex]
Substituting the values, we have:
[tex]\left[\begin{array}{ccc}3&37\\-1&-9\end{array}\right] v_1 = 0[/tex]
Solving the system of equations, we find v1 = [37 -3].
For [tex]\lambda_2 = -3[/tex]:
[tex](A - \lambda_2I)v_2 = 0[/tex]
Substituting the values, we have:
[tex]\left[\begin{array}{ccc}12&37\\-1&0\end{array}\right] v_2 = 0[/tex]
Solving the system of equations, we find [tex]v_2[/tex] = [-37 12].
Therefore, the general solution to the linear system of differential equations is:
[tex]X(t) = c_1 * e^{6t} * [37 \ \ -3] + c_2 * e^{-3t} * [-37\ \ 12][/tex]
where [tex]c_1\ and\ c_2[/tex] are constants.
b) The solution curves to this linear system represent trajectories in the state space. The behavior of the solution curves depends on the eigenvalues.
Since we have [tex]\lambda_1 = 6[/tex] and [tex]\lambda_2 = -3[/tex], the system has one positive eigenvalue and one negative eigenvalue. This indicates that the solution curves will exhibit a combination of exponential growth and decay.
As t approaches infinity, the exponential term with [tex]e^{-3t}[/tex] will dominate, and the solution curves will converge towards the eigenvector associated with the negative eigenvalue, [-37 12].
On the other hand, as t approaches negative infinity, the exponential term with [tex]e^{6t}[/tex] will dominate, and the solution curves will diverge away from the origin in the direction of the eigenvector associated with the positive eigenvalue, [37 -3].
In summary, the solution curves will either converge or diverge depending on the initial conditions, and as t approaches infinity, they will converge towards the eigenvector associated with the negative eigenvalue.

An airplane is flying in a direction of 75° north of east at a constant flight speed of 300 miles per hour. The wind is blowing due west at a speed of 25 miles per hour. What is the actual direction of the airplane? Round your answer to the nearest tenth. Show your work. PLS PLS PLSPLS HELP URGANT
Answer:
79.7°
Step-by-step explanation:
We resolve the speed of the plane into horizontal and vertical components respectively as 300cos75° and 300sin75° respectively. Since the wind blows due west at a speed of 25 miles per hour, its direction is horizontal and is given by 25cos180° = -25 mph. We now add both horizontal components to get the resultant horizontal component of the airplane's speed.
So 300cos75° mph + (-25 mph) = 77.646 - 25 = 52.646 mph.
The vertical component of its speed is 300sin75° since that's the only horizontal motion of the airplane. So the resultant vertical component of the airplane's speed is 300sin75° = 289.778 mph
The direction of the plane, Ф = tan⁻¹(vertical component of speed/horizontal component of speed)
Ф = tan⁻¹(289.778 mph/52.646 mph)
Ф = tan⁻¹(5.5043)
Ф = 79.7°
