The correct option that describes the vertical asymptote is; B: There is a vertical asymptote at x = 4 because Limit of g (x) as x approaches 4 minus = infinity and limit of g (x) as x approaches 4 plus = infinity

A vertical asymptote of a graph is defined as a vertical line x = a where the graph tends toward positive or negative infinity as the inputs approach a.

A vertical asymptote is a value of x for which the function is not defined, that is, it is a point which is outside the domain of a function;

In a graph, these vertical asymptotes are given by dashed vertical lines.

An example is a value of x for which the denominator of the function is 0, and the function approaches infinity for these values of x.

We are given the function;

g(x) = 2(x + 4)²/(x² - 16)

Simplifying the denominator gives;

(x² - 16) = (x + 4)(x - 4)

Thus, our function is;

g(x) = 2(x + 4)²/[(x + 4)(x - 4)]

(x + 4 ) will cancel out to give;

g(x) = 2(x + 4)/(x - 4)

The supplement of BIE equals the supplement of GMD is a false assertion if lines BG and CF are parallel.

Angles with a supplementary sum are those whose sum is 180 degrees. For instance, the total of angle 130° and angle 50° is 180°, hence they are supplementary angles.

Lines BG and CF are parallel, as shown in the figure.

If BIE = X, then its supplement of BIE will be 180 - X;

similarly, if GMD = Y, then its supplement of GMD will be 180 - Y.

Since BG and CF are parallel, the supplements of BIE and GMD are interior angles on the same side ( as shown in figure)

and for parallel line the interior angle on the same side is 180

so 180 - X and 180 -Y there sum should be 180

They cannot be equal

The matrix equation Ax=b with one unique solution says that column A is linearly independent.

Two vectors are linearly dependent if at least one of them can be expressed as a linear combination of the others. If no vector can be expressed as a linear combination of the others, then two or more vectors are said to be linearly independent.

Given the matrix equation is Ax=b. And this equation has one unique solution. Then, let us assume this unique solution is x₁.  Let the column values of A be A₁, A₂, A₃, .... Aₙ.

If there is only one solution to the equation Ax = b for all b, then assume b = 0 and come to the conclusion that there is only one solution to the equation Ax = 0 as well. Consequently, the only solution is straightforward, and the columns of A are linearly independent.

Answer:

Your answer is x = 47.

Step-by-step explanation:

First, you need to move the constant to the right-hand side and change its sign.

4x = 180 + 8

Now, you need to add the numbers.

4x = 188

Last but not least, you need to divide both sides of the equation by 4, which gets you to:

x = 47

The total amount paid during the lease period is £45,665.64.

To find the total amount paid during the lease period, we need to add the initial payment of £10,000 to the present value of the four equal payments, which can be calculated using the present value formula:

PV = FV / (1 + r)^n

Where PV is the present value, FV is the future value, r is the discount rate, and n is the number of periods. In this case, the present value of the four equal payments is £26,496, the discount rate is 8%, and the number of periods is 4. We can solve for the future value by rearranging the formula:

FV = PV × (1 + r)^n

Plugging in the given values, we get:

FV = £26,496 × (1 + 0.08)^4

FV = £26,496 × 1.34

FV = £35,664.64

This is the total future value of the four payments. To find the total amount paid during the lease period, we need to add this to the initial payment of £10,000. Therefore, the total amount paid during the lease period is:

£35,664.64 + £10,000 = £45,665.64

Therefore the total amount paid during the lease period is £45,665.64.

The four integers say a,b,c and d. If a and b are congruent to moulo m and c ,d are congruent to modulo m then ac and bd are must be congruent to modulo m .

Two integers a and b are "congruent modulo n" if their difference is a multiple of n or in other words we say n/(b-a) . For example, 17 and 5 are congruent modulo 3 because 17 - 5 = 12 = 4×3

We have, a ≡ b mod m => m/(a - b)

and c ≡ d mod m => m/(c-d)

Now, a + c - b - d = (a-b) + (c-d)

because, m/( a - b) and m/(c-d)

=> m/( a-b+ c-d )

=> m/(a+c)-(b+d)

=> a+c ≡ b+d mod m

We have to prove that ac ≡ bd mod m.

ac - bd = c(a-b) + b(c- d)

Now, as we see, m/(a-b) => m/c(a-b)

and m/(c-d) => m/b(c-d)

=> m/(c(a-b) + b(c-d))

=> m/(ac - bc + bc - bd)

=> m/(ac - bd)

=> ac ≡ bd mod m

When a user accesses a website through HTTPS and the browser initially starts to enquire about the website's origin server, a TLS handshake occurs

Together, the client and server will perform the following during a TLS handshake:

Indicate the TLS version (TLS 1.0, 1.2, 1.3, etc.) they'll be using.

Select the cipher suites they'll employ (see list below).

Using the server's public key and the SSL certificate authority's digital signature, confirm the server's identity.

For instance, a matrix contains two rows and three columns. a group of integers organized in a rectangular array in rows and columns. Matrix elements or entries refer to numbers. In several disciplines of engineering, physics, economics, statistics, and mathematics, matrices have a wide range of applications.

The eigenvalues and eigenvectors of the sum of two matrices are typically not the same as the sums of the eigenvalues and eigenvectors of the individual matrices. In actuality, there is no way to separate the eigenvalues of A and B from one another.

When a vector v is an eigenvector of both A and B, it is also an eigenvector of A+B, with an eigenvalue equal to the sum of its eigenvalues for A and B, respectively. There is, however, no reason to anticipate that two matrices will share an eigenvector in general. There is no method to create an eigenvector of A+B from two random eigenvectors of A and B alone.

When the matrices A and B commute, or when they fulfill AB=BA, this is a significant exception.

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (0, 4) and (8, 0).

Now,

Since, The equation of line passes through the points (0, 4) and (8, 0)

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (0 - 4) / (8 - 0)

m = - 4 / 8

m = -1/2

We know that, The slopes of parallel lines are equal.

Thus, The equation of line with slope -1/2 is,
