The inverse function, given the function f(x) = 5(x+4) - 6, can be found to be A. 1.

First, we need to find the inverse function of f(x). To do this, we'll switch the roles of x and y (we'll use y to represent f(x)) and then solve for y.

Given the function f(x) = 5(x + 4) - 6, let's replace f(x) with y:

y = 5(x + 4) - 6

x = 5(y + 4) - 6

x = 5y + 20 - 6

x = 5y + 14

x - 14 = 5y

y = (x - 14) / 5

Now we have the inverse function, f^(-1)(x) = (x - 14) / 5. To find the value of the inverse function when x = 19, plug in 19 for x:

f^(-1)(19) = (19 - 14) / 5

f^(-1)(19) = 5 / 5

f^(-1)(19) = 1

\( \sf \longrightarrow \: {x}^{2} + 3x - 4\)

\( \sf \longrightarrow \: {x}^{2} + 4x - 1x - 4\)

\( \sf \longrightarrow \: x(x + 4) \: - 1(x + 4)\)

\( \sf \longrightarrow \: (x + 4) \: (x - 1) \\ \)

Option C) (x + 4) (x - 1)

The factors of the expression x² + 3x - 4 are (x + 4) and (x - 1).

Option C is the correct answer.

We have,

To find the factors of the quadratic expression x² + 3x - 4, we can use either factoring by grouping or the quadratic formula.

In this case, we can factor it by splitting the middle term.

The expression is x² + 3x - 4.

Step 1:

Split the middle term (3x) into two terms whose product is equal to the product of the first and last coefficients (x² * -4 = -4x²) and whose sum is equal to the middle coefficient (3x).

The two terms are 4x and -x because 4x * -x = -4x² and 4x + (-x) = 3x.

Step 2:

Now, we rewrite the expression using the split terms:

x² + 4x - x - 4

Step 3:

Factor by grouping:

(x² + 4x) + (-x - 4)

Step 4:

Factor out the common terms from each group:

x(x + 4) - 1(x + 4)

Step 5:

Notice that both terms have a common factor of (x + 4):

(x + 4)(x - 1)

Thus,

The factors of the expression x² + 3x - 4 are (x + 4) and (x - 1).

The equations of the tangents to the graph at the points where the tangents to the graph have a slope of 9 are:x - y + 9 = 0 9x - y - 48 = 0,  9y + x + 60 = 0 x + y + 70 = 0

Let us consider the graph of the equation y = x³ + 3x²n - 15x - 20. The derivative of the given equation is:y = x³ + 3x²n - 15x - 20 y' = 3x² + 6xn - 15We can put this equation in the form of y = m(x - a) + b, where m is the slope of the tangent line and (a, b) is the point of tangency.

Therefore, we can equate y = m(x - a) + b and y = x³ + 3x²n - 15x - 20 to find the coordinates of the point of tangency:

For a slope of 9:3x² + 6xn - 15 = 9Solving for x, we get:x = n - 1, x = -n - 5Substituting the first value of x, we get:y = (9(n - 1))x - 2n² + 21n - 19Substituting the second value of x, we get:y = (9(-n - 5))x + 46n + 55

Therefore, the equations of the tangents to the graph at the points where the tangents to the graph have a slope of 9 are:x - y + 9 = 0 9x - y - 48 = 0 9y + x + 60 = 0 x + y + 70 = 0

The reason why product rule works is because the derivative of a product is not simply the product of the derivatives of the two functions as one might initially think.

In calculus, the rule helps to find derivative of the product of two functions and states derivative of product of 2 functions is = [First function * derivative of the second function} +  [Second function * derivative of the first function}.

When we have 2 functions f(x) and g(x) and need find the derivative of their product, we use the product rule. Its takes into account the fact that when we differentiate a product, we need to account for both functions changing at the same time.

By breaking the product down into two parts and taking the derivative of each part separately, we can then add them together using the product rule to get the overall derivative of the product.

False. The statement is not necessarily true. While it is possible to have word embeddings that are 10000 dimensional for a vocabulary of 10000 words.

It is not a requirement to capture the full range of variation and meaning in those words. The dimensionality of word embeddings is not solely determined by the size of the vocabulary, but rather by various factors such as the complexity of the underlying semantic relationships and the specific modeling techniques used.

In practice, word embeddings are often created using techniques like Word2Vec or GloVe, which typically produce lower-dimensional embeddings (e.g., 100 to 300 dimensions). These lower-dimensional embeddings have been shown to effectively capture important semantic relationships and patterns in language, while also reducing the computational complexity and memory requirements. The choice of dimensionality depends on the specific application and the trade-off between capturing sufficient information and computational efficiency.

To calculate an augmented matrix, first write the coefficients of the variables in the equation in one matrix. Then, add the constants on the right side of the equation to the end of the matrix. This will form the augmented matrix.

An augmented matrix is a matrix composed of a coefficient matrix and a constant vector. It is used to represent a system of linear equations. To calculate an augmented matrix, first write the coefficients of the variables in the equation in one matrix. For example, in the equation 2x + 3y = 5, the coefficients are 2 and 3. The matrix would look like [2 3]. Then, add the constants on the right side of the equation to the end of the matrix. In this example, the constant is 5, so the augmented matrix would look like [2 3 5]. This augmented matrix can then be used to solve the linear equation. It can be used to row reduce the matrix to find the solutions of the variables, or it can be used with other methods such as Cramer's Rule or Gaussian Elimination.

Answer:

  C.  142°

Step-by-step explanation:

You want the angle between vectors u=3i+√3j and v=-2i-5j.

There are a number of ways the angle between the vectors can be found. For example, the dot-product relation can give you the cosine of the angle:

  u•v = |u|·|v|·cos(θ) . . . . . . where θ is the angle of interest

You can find the angles of the vectors individually, and subtract those:

  u = |u|∠α

  v = |v|∠β

  θ = α - β

When the vectors are expressed as complex numbers, the angle between them is the angle of their quotient:

  \(\dfrac{\vec{u}}{\vec{v}}=\dfrac{|\vec{u}|\angle\alpha}{|\vec{v}|\angle\beta}=\dfrac{|\vec{u}|}{|\vec{v}|}\angle(\alpha-\beta)=\dfrac{|\vec{u}|}{|\vec{v}|}\angle\theta\)

This method is used in the calculation shown in the first attachment. The angle between u and v is about 142°.

A graphing program can draw the vectors and measure the angle between them. This is shown in the second attachment.

Additional comment

The approach using the quotient of the vectors written as complex numbers is simply computed using a calculator with appropriate complex number functions. There doesn't seem to be any 3D equivalent.

The dot-product relation will work with 3D vectors as well as 2D vectors.

To find a possible equation of the inverse log function, we can use the properties of exponential functions and logarithms.

We know that the given exponential function has a base of 3, an asymptote at y = -6, and passes through the point (2, 3).

The general form of an exponential function with base 3 is:

y = a * \(3^x\)

Since the exponential function has an asymptote at y = -6, we can set the limit as x approaches negative infinity to determine the value of "a":

lim(x->-∞) \(a * 3^x = -6\)

As x approaches negative infinity, the value of\(3^x\) becomes very close to 0, and the equation simplifies to:

a * 0 = -6

Since any value multiplied by 0 is 0, we can conclude that "a" must be 0 in this case.

Thus, the equation of the exponential function with base 3 becomes:

y = 0 * \(3^x\) = 0

The inverse function of y = 0 is x = 0.

Therefore, a possible equation for the inverse logarithmic function is:

x = log₃(y)

This equation represents the inverse relationship between the original exponential function and the logarithmic function.

The probability that exactly three out of two hundred randomly chosen individuals will have the disease is approximately 0.1668 or 16.68%.

To solve this problem, we need to use the binomial distribution formula. The binomial distribution is a probability distribution that describes the number of successes in a fixed number of independent trials, where each trial has only two possible outcomes (success or failure) and the probability of success is constant.

In this case, the probability of success is 1.2%, which is equivalent to 0.012. The number of trials is 200, and we want to know the probability of exactly three successes.

The formula for the probability of exactly k successes in n trials is:

P(k) = (n choose k) * p^k * (1-p)^(n-k)

where "n choose k" represents the number of ways to choose k items from a set of n items, and p is the probability of success.

Using this formula and plugging in the values we have, we get:

P(3) = (200 choose 3) * 0.012^3 * (1-0.012)^(200-3)

P(3) = (200! / (3! * 197!)) * 0.012^3 * 0.988^197

P(3) = 0.1668

Therefore, the probability that exactly three out of two hundred randomly chosen individuals will have the disease is approximately 0.1668 or 16.68%. This means that if we were to repeat this experiment many times, we would expect to see about 16.68% of the time that exactly three people out of two hundred have the disease.
