Answer:

n = m - a

Step-by-step explanation:

Given:

a = m − n

Where,

Actual cost of the item = a

Original price of the item = m

Amount of Coupon = n

Solve the formula for the amount of the coupon

Making n the subject

a = m − n

Subtract m from both sides

a - m = m - n - m

a - m = - n

Divide both sides by -1

(a - m) / -1 = -n / -1

- a + m = n

Can also be written as

n = m - a

the proportions are the same the function is linear.

What is a function?

A function is a special form of relation where each input has exactly one output. In other words, for each input value, the function returns exactly one value. A relation rather than a function is depicted in the above graph since one is mapped to two different values. However, if one were instead mapped to a single value, the relationship described above would change into a function. Furthermore, output values could match input values exactly.

The function machine receives the x-values as input. After finishing its operations, the function machine produces the y-values. Any function may be the one within.

Answer: A. It is a straight line that passes through the origin.

The value of cos A in the triangle is 1 / 9.

The triangle is given as ABC. The side lengths are a, b and c. Therefore, cos A of the triangle can be found using cosine rule as follows:

a² = b² + c² - 2bc cos A

a = 4

b = 3

c = 3

Therefore,

4² = 3² + 3² - 2(3)(3) cos A

16  = 9 + 9 - 18 cos A

16 - 18 = - 18 cos A

-2 = - 18 cos A

divide both sides by - 18

cos A = - 2 / - 18

The length of the edge of the square is increasing at a rate of 12/13 cm/min when the area is 169 cm^2, given that the area of the square is increasing at a rate of 24 cm^2/min.

Let's assume that the side length of the square is represented by "x" and the area of square is represented by "A". Then we have:

A = x^2

Differentiating both sides with respect to time "t", we get:

dA/dt = 2x(dx/dt)

Given that dA/dt = 24 cm^2/min, we can find dx/dt when A = 169 cm^2 (which is the area of a square with side length of 13 cm):

24 = 2(13)(dx/dt)

Simplifying this expression, we get:

dx/dt = 24/(26) = 12/13

Therefore, the length of the edge of the square is increasing at a rate of 12/13 cm/min when the area is 169 cm^2.

The estimated local maximums are (0,-2) and (0,π), and the estimated local minimums are (0,0) and (0,2π).

The graph of f consists of two parts: a line increasing to (0,-2) and a curve starting at (0,0) and intercepting the x-axis at (0, π, and 2π). To estimate the local maximum and local minimum of the graph, we need to look for points where the function changes direction.For the line segment, the graph is increasing until it reaches (0,-2). This point can be considered a local maximum because the graph starts decreasing afterward.

For the curve, we have points at (0,0), (0, π), and (0, 2π). At (0,0), the graph is flat and does not change direction, so it is considered a local minimum.

At (0,π), the graph changes direction from increasing to decreasing, making it a local maximum.Similarly, at (0, 2π), the graph changes direction from decreasing to increasing, which means it is also a local minimum.Therefore, the estimated local maximums are (0,-2) and (0,π), and the estimated local minimums are (0,0) and (0,2π).

If you detect the electron passing through the left slit in a double-slit experiment, the probabilities associated with it will depend on the specific setup and conditions of the experiment.

In a basic double-slit experiment, where a beam of electrons or particles is directed towards two slits, the probability of detecting the particle at a particular location on the screen depends on the interference pattern formed by the interaction of the wave-like nature of the particles. When the electron passes through the left slit, it implies that the particle's wavefunction has "collapsed" or "localized" to a specific position associated with the left slit. In this case, the probability of detecting the electron at a specific location on the screen will be concentrated around the corresponding position associated with the left slit. The probability distribution on the screen will generally show a pattern characterized by a central maximum and alternating regions of constructive and destructive interference, depending on the relative distances between the slits, the screen, and the wavelength of the particle. It's important to note that the specific probabilities associated with detecting the electron at different positions on the screen will vary depending on the details of the experimental setup, such as the dimensions of the slits, the distance between the slits and the screen, and the wavelength of the particles. To determine the exact probabilities, one would need to know the specifics of the experiment and apply the principles of quantum mechanics and wave-particle duality to calculate or measure the probabilities associated with the electron passing through the left slit.

Again, cube root is not a number.

As a result, this is not possible.

Case-5: Assume the power of 2 is 5.

2⁵ + x³ = 155

Again, cube root is not a number.

As a result, this is not possible.

Case-6: Assume the power of two is six.

2⁶ + x³ = 155

so,

x³ = 155 - 64 = 91

Again, cube root is not a number.

As a result, this is not possible.

Case-7: Assume the power of 2 is 7.

2⁷ + x³ = 155

The topologies {∅, {x}, {y}, {z}, {x, y, z}} and {∅, {x}, {y}, {z}, {x, y}, {y, z}, {x, z}} satisfy both the Frechet and Hausdorff properties.

To find all possible topologies of the space  = {x, y, z}, we need to consider all the possible subsets of this set. Since the set has three elements, there are 2^3 = 8 possible subsets.
The possible topologies are as follows:
1. {∅, {x, y, z}}: This is the trivial topology, where the whole set and the empty set are the only open sets.
2. {∅, {x}, {y}, {z}, {x, y, z}}: This is the discrete topology, where every subset of the set is open.
3. {∅, {x}, {y}, {z}, {x, y}, {y, z}, {x, z}, {x, y, z}}: This is the indiscrete or trivial topology, where only the whole set and the empty set are open.
4. {∅, {x}, {y}, {z}, {x, y}, {y, z}, {x, z}}: This is a topology that is not discrete or indiscrete.

To determine which of these topologies satisfy the Frechet property and the Hausdorff property, we need to consider the limit points and the ability to separate points, respectively.
The Frechet property states that for every point x in a set A, there exists a sequence of points in A that converges to x. In other words, every point is a limit point.
The Hausdorff property states that for any two distinct points x and y in a set A, there exist disjoint open sets U and V such that x is in U and y is in V. In other words, every pair of distinct points can be separated by open sets.

Let's analyze each topology:
1. {∅, {x, y, z}}: This topology does not satisfy the Frechet or Hausdorff property because it does not have any limit points or allow for the separation of points.
2. {∅, {x}, {y}, {z}, {x, y, z}}: This topology satisfies both the Frechet and Hausdorff properties. Any point x can be approached by the sequence (x), and any two distinct points can be separated by open sets.
3. {∅, {x}, {y}, {z}, {x, y}, {y, z}, {x, z}, {x, y, z}}: This topology does not satisfy the Frechet or Hausdorff property because it does not have any limit points or allow for the separation of points.
4. {∅, {x}, {y}, {z}, {x, y}, {y, z}, {x, z}}: This topology satisfies both the Frechet and Hausdorff properties. Any point x can be approached by the sequence (x), and any two distinct points can be separated by open sets.
