Answer:

inverse: \(f^{-1}(x) = \sqrt[5]{x^3 - 5}\)

                                            explanation:

Given: f(x) = \((x^5 +5)^{\frac{1}{3} }\)

let f(x) be y

y =  \((x^5 +5)^{\frac{1}{3} }\)

To find inverse, make x the subject.

\(y^3 = x^5 + 5\)

\(y^3 - 5 = x^5\)

\(x = \sqrt[5]{y^3 - 5}\)

change signs:

\(f^{-1}(x) = \sqrt[5]{x^3 - 5}\)

Given that tanx=10 and sinx is positive, Therefore, `sin(2x) = 20/101`, `cos(2x) = 0`, and `tan(2x) = -1/5`.

We can start by using the identity:

\(tan^2(x) + 1 = sec^2(x)\)

to solve for cos(x) and sec(x)

Since `tan(x) = 10` we have:

\(tan^2(x) = 100\)

Using the identity\(tan^2(x) + 1 = sec^2(x)\) we get:

\(sec^2(x) = tan^2(x) + 1 = 100 + 1 = 101\)

So \(sec(x) = \sqrt{101}\).

Since `sin(x)` is positive and\(sin^2(x) + cos^2(x) = 1\), we can use\(cos(x) =\sqrt{ (1 - sin^2(x))}\)to solve for `cos(x)`.

Using \(tan(x) = sin(x)/cos(x)\)we can solve for `sin(x)`:

\(tan(x) = sin(x)/cos(x)\)

\(10 = sin(x)/\sqrt{101}\)

\(sin(x) = 10 * \sqrt{101} /101\)

Now that we have `sin(x)` and `cos(x)`, we can use the double angle formulas:

sin(2x) = 2sin(x)cos(x)

cos(2x) = cos^2(x) - sin^2(x)

\(tan(2x) =\frac{ (2tan(x))}{(1 - tan^2(x))}\)

Plugging in the values we calculated earlier, we get:

\(sin(2x) = 2(10 *\sqrt{101}/101) * (1/\sqrt{101} ) = 20/101`\)

cos(2x) = (1 - 101/101) = 0

tan(2x) = (2 * 10)/(1 - 100) = -1/5

Therefore, `sin(2x) = 20/101`, `cos(2x) = 0`, and `tan(2x) = -1/5`.

a. The system in this situation is the two marbles.

b. The marbles' momentums before the collision is 100 g cm/s.

c. The momentum of marble C after the collision is 40 g*cm/s.

d. The momentum of marble D after the collision is 160 g*cm/s.

e. The speed of marble D after the collision is 16.0 cm/s.

a. We can sketch the situation as follows:

Before the collision:

Marble C --------------->

Marble D --------------->

After the collision:

Marble C --------------->

Marble D --------------->

The system in this situation is the two marbles. The before and after situations refer to the state of the system before and after the collision. We can set up a coordinate system with the positive direction being the direction in which the marbles are moving.

b. The momentum of marble C before the collision is given by p_C = m_C * v_C = 5.0 g * 20.0 cm/s = 100 gcm/s. The momentum of marble D before the collision is given by p_D = m_D * v_D = 10.0 g * 10.0 cm/s = 100 gcm/s.

c. The momentum of marble C after the collision is given by p_C = m_C * v_C = 5.0 g * 8.0 cm/s = 40 g*cm/s.

d. The total momentum of the system before the collision is p_before = p_C + p_D = 100 gcm/s + 100 gcm/s = 200 gcm/s. The total momentum of the system after the collision is p_after = p_C + p_D = 40 gcm/s + p_D. Since momentum is conserved, p_before = p_after, so 200 gcm/s = 40 gcm/s + p_D. Solving for p_D gives p_D = 160 g*cm/s.

e. The speed of marble D after the collision is given by v_D = p_D / m_D = 160 g*cm/s / 10.0 g = 16.0 cm/s.

The equation of the parabola in the given graph is:

y = 2(x + 3)² + 1

Remember that for a parabola whose vertex is (h, k) and leading coefficient is a can be written as:

y = a(x - h)² + k

Here we can see that the vertex is at (-3, 1), then we can write:

y = a(x + 3)² + 1

Now, notice that the parabola opens upwards, which means that the leading coefficient must be positive.

The domain is the set with the first values of each pair, the range is the set with the second value of each pair.

A relation maps elements from a set, the domain, into another set, the range.

Such thar a relation is represented by pairs (a, b), where it means that the element a is being mapped into the element b. (So, a is in the domain, and b in the range)

In this case, our relation is represented by:

{(-3, 2), (-2, 1), (-1,0), (0, -1)}

The domain is the set with the first values of each pair, the range is the set with the second value of each pair.

To find the expected number of times Joan rolls a 3, we use the formula for mean of a binomial distribution.

The correct option is, option (C) 6.

The probability of rolling a number 3 on any given roll is 1/4

If Joan rolls the die 20 times, the number of times she rolls a 3 will follow a binomial distribution with n = 20 (number of trials) and p = 1/4 (probability of success).

The formula for the probability mass function of a binomial distribution is:

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

where X is the random variable representing the number of successes (the number of times Joan rolls a 3), k is the number of successes, n is the number of trials, p is the probability of success, and (n choose k) is the binomial coefficient, which represents the number of ways to choose k items from a set of n items.

Using this formula, we can calculate the probability of rolling a 3 exactly k times out of 20 rolls:

P(X=k) = (20 choose k) * (1/4)^k * (3/4)^(20-k)

To find the expected number of times Joan rolls a 3, we can use the formula for the mean of a binomial distribution:

E(X) = n * p

In this case, E(X) = 20 * 1/4 = 5

Therefore, the expected number of times Joan rolls a 3 is 5.

Since the possible answers are integers, the closest answer to 5 is 6. Therefore, the answer is (C) 6.

the partial regression coefficients in a multiple regression model represent the expected change in the dependent variable associated with a unit change in the corresponding independent variable, holding other variables constant.

In the context of the three-variable model Yt = α1 + α2x2+ a3x3 where α2 and α3 are partial regression coefficients, the coefficients represent the changes in Y associated with a unit change in x2 and x3, respectively. The partial regression coefficient represents the expected change in Y when x2 or x3 increases by one unit, while keeping other variables constant.
The partial regression coefficient for α2, α2, measures the effect of the variable x2 on Y. It tells us how much Y is expected to change for every unit increase in x2, holding the other variables constant. Similarly, the partial regression coefficient for α3, α3, measures the effect of the variable x3 on Y, and tells us how much Y is expected to change for every unit increase in x3, holding the other variables constant.
It is important to note that the regression coefficients are estimates obtained from sample data, and are subject to sampling variability. Therefore, it is important to consider the uncertainty associated with the estimates when interpreting the results.

False, The eigenvalues of a matrix A are not same as the eigenvalues of the reduced row echelon form of A.

A matrix's eigenvalues are not the same as those of the matrix's reduced row echelon form, contrary to what is claimed.

This is due to the fact that when a matrix is reduced to its echelon form via row operations, its eigenvalues may not always stay the same. The eigenvalues of a matrix may be different in the reduced row echelon form than they are in the original matrix as a result.

Think about these matrices as an illustration:

Likewise, B's reduced row echelon form is B, and B's eigenvalues are both 1.

A = [1 2; 2 1]

and

B = [1 0; 0 1].

The eigenvalues of a matrix and its reduced row echelon form are thus typically not the same.

FALSE. The eigenvalues of a matrix A are NOT the same as the eigenvalues of the reduced row echelon form of A.

Explanation:

Eigenvalues are scalar values that, when multiplied by an eigenvector, produce the same effect as the original matrix A on that eigenvector. Mathematically, for a matrix A and its eigenvector v, Av = λv, where λ is the eigenvalue.

Row echelon form is a matrix transformation using elementary row operations to obtain a triangular form. The reduced row echelon form (RREF) is a further simplified version of the row echelon form.

However, transforming a matrix A to its RREF changes the properties of the matrix, and therefore the eigenvalues of matrix A and its RREF are generally not the same. The eigenvalues are preserved only under specific matrix transformations, such as similarity transformations, which row echelon form is not one of them.
