A line contains two distinct points, C and D. Select each correct statement,
Points C and D determine one unique line,
There are infinitely many points between points C and D.
The distance from C to D is equal to the distance from D to C.
O Any line segment that contains point C must also contain point D.

In this step, we need to find the x-intercepts where the polynomial function f(x) = (x+4)²(x - 3)³(x - 2) crosses the x-axis. We are asked to select the number of x-intercepts and provide them as ordered pairs.

To find the x-intercepts of the polynomial function f(x) = (x+4)²(x - 3)³(x - 2), we set the function equal to zero and solve for x.

Setting f(x) = 0, we have (x+4)²(x - 3)³(x - 2) = 0. By applying the zero-product property, we can set each factor equal to zero and solve for x separately.

Thus, we set (x+4) = 0, (x - 3) = 0, and (x - 2) = 0. Solving these equations, we find three distinct x-intercepts: x = -4, x = 3, and x = 2.

Therefore, the function f(x) crosses the x-axis at these three points. Expressing them as ordered pairs, the intercepts are (-4, 0), (3, 0), and (2, 0).

a) Marathon Incorporated can deduct $0 of the dividend payment in determining its taxable income. b)  Guy will pay $4,070 in tax on the $11,000 dividend he received. c) Little Rock Corporation will pay $0 in tax on the $33,000 dividend it received from Marathon Incorporated.

a) Marathon Incorporated can deduct $0 of the dividend payment in determining its taxable income. This is because the dividends distributed to shareholders are not deductible expenses for the corporation. Dividends are paid out of after-tax profits and are not considered a deductible expense for the distributing corporation.

b) Guy will pay $4,070 in tax on the $11,000 dividend he received from Marathon Incorporated, including the net investment income tax. To calculate the tax, we need to consider Guy's marginal ordinary tax rate and the net investment income tax. Assuming Guy's marginal ordinary tax rate is 37 percent, the tax on the dividend would be $4,070 (0.37 * $11,000). The net investment income tax is an additional 3.8 percent tax on investment income for individuals with certain income thresholds, so it would also apply to the dividend income received by Guy.

c) Little Rock Corporation will pay $0 in tax on the $33,000 dividend it received from Marathon Incorporated. This is because C corporations are eligible for a 50 percent dividends-received deduction. The dividends-received deduction allows corporations to exclude 50 percent of the dividends received from taxable income. In this case, Little Rock Corporation would be able to exclude $16,500 (50 percent of $33,000) from its taxable income, resulting in a tax liability of $0 on the dividend income.

The surface area of earth is 514.4million \(Km^{2}\) and the volume of the Earth is 1.1 ×\(10^{12}\) \(Km^{3}\).

Radius of Earth = 6400 (approximately).

Earth is a sphere. So by using the formula of Surface Area of sphere we can calculate the Surface area of earth as follows,

Surface Area of Earth = 4\(\pi r^{2}\) = 4 × (3.14) × \((6400)^{2}\)

                                    =  4 × 3.14 × 40960000

                                    = 514457600 \(Km^{2}\)

                                    = 514.4million \(Km^{2}\)

The surface area of earth is 514.4million \(Km^{2}\) .

Similarly, by using the formula of volume of sphere we can calculate the volume area of earth as follows,

Volume of Earth = (4/3)\(\pi r^{3}\)

                           = (4/3)×(3.14)×\((6400)^{3}\)

                           =(1.3333)(3.14)(2.6214 × \(10^{11}\))

                           = 1.0975 × \(10^{12}\) \(Km^{3}\)

                           = 1.1 ×\(10^{12}\) \(Km^{3}\)

Answer:

16,800 Liters

Step-by-step explanation:

Convert 3/4 into eighths, because it was already 1/8 full before the 10,500 liters were added:

3/4= 6/8

Subtract 1/8 from that (because it was already 1/8 full):

6/8-1/8= 5/8

Divide 10,500 by the 5 (because you want how many liters each part is):

10,500/5= 2,100

You know can say that every eighth is 2,100 Liters of water.

Multiply that by the 8 total parts it can hold:

2,100x8= 16,800 Liters

Answer:

16800

Step-by-step explanation:

1/8 ÷ 3/4 × 10500/1

1/8 × 4/3 × 10500/1

1/5× 10500/1

= 2100× 8

The solution to the 1-dimensional heat equation problem with the given initial and boundary conditions is \(u(x, t) = \sum_{n=1}^\infty \frac{(-1)^n}{n\pi} \sin\left(\frac{n\pi x}{5}\right) e^{-(n\pi)^2 \frac{2t}{25}}\).

We are given the one-dimensional heat equation:

\(\frac{\partial u}{\partial t} = 2 \frac{\partial^2 u}{\partial x^2}\)

We need to find the solution u(x, t) subject to the initial condition u(x, 0) = f(x) and boundary conditions u(0, t) = u(5, t) = 0 for t > 0.

To solve this problem, we use separation of variables:

u(x, t) = X(x)T(t)

Substituting this into the heat equation and dividing by u(x, t), we obtain:

\(\frac{1}{T(t)}\frac{dT}{dt} = \frac{2}{X(x)}\frac{d^2X}{dx^2}\)

Both sides are equal to a constant, which we denote by -λ². We then obtain two ordinary differential equations:

\(\frac{d^2X}{dx^2} + \lambda^2X = 0\)

\(\frac{1}{T} \frac{dT}{dt} = -\frac{\lambda^2}{2}\)

The general solution to the first equation is:

\(X(x) = A \sin\left(\frac{\pi x}{L}\right) + B \cos\left(\frac{\pi x}{L}\right)\)

where L = 5 is the length of the interval and A, B are constants determined by the boundary conditions.

The second equation has the solution:

\(T(t) = Ce^{-\lambda^2t/2}\)

where C is a constant determined by the initial condition.

The general solution to the heat equation is then:

\(u(x,t)=\sum\limits_{n=1}^{\infty}\left(A_n\sin\left(\frac{n\pi x}{5}\right) + B_n\cos\left(\frac{n\pi x}{5}\right)\right)e^{-\frac{n^2\pi^2t}{5^2}}\)

where the sum is taken over all positive integers n.

Using the initial condition, we can determine the coefficients A_n and B_n as:

A_n = \((-1)^n \frac{(4n\pi\sin(n\pi) - 3\sin(2n\pi))}{n^3\pi^3}\)

B_n = 0

Therefore, the solution to the given problem is:

\(u(x, t) = \sum_{n=1}^\infty \frac{(-1)^n}{n\pi} \sin\left(\frac{n\pi x}{5}\right) e^{-(n\pi)^2 \frac{2t}{25}}\)

If $550 is deposited in an acount paying 8.6% annual interest, compounded semiannually the account will take approximately 5.2 years to increase to $850.

To calculate the time it takes for the account to increase to $850, we can use the formula for compound interest:

\(A = P(1 + r/n)^{(nt)\)

Where:

A is the final amount ($850),

P is the initial deposit ($550),

r is the annual interest rate (8.6% or 0.086),

n is the number of times the interest is compounded per year (semiannually, so n = 2),

and t is the time in years.

Rearranging the formula to solve for t, we have:

t = (1/n) * log(A/P) / log(1 + r/n)

Plugging in the values, we get:

t = (1/2) * log(850/550) / log(1 + 0.086/2)

Calculating this expression gives us approximately 5.2 years, rounded to the nearest tenth. Therefore, it will take around 5.2 years for the account to increase to $850.

According to Euclidean geometry, a square is an equilateral quadrilateral with four equal sides and four equal angles. It is also referred to as a rectangle with two neighbouring sides of equal length. A square is an equilateral quadrilateral because it has four equal sides and four equal angles. Square angles are 90-degree or straight angles. Furthermore, the diagonals of the square are evenly spaced and split at a 90-degree angle. a neighbouring rectangle with two equal sides. a quadrilateral with four equal-length sides and four right angles. A parallelogram with two adjacent, equal sides forming a right angle. A rhombus with straight sides.

The Pythagorean theorem can be used to find the square's diagonal:

2x2 = diagonal2 = x2 + x2 = 2x2\(x * \sqrt = diagonal = sqrt(2x2) (2)\)

Because the diagonal equals the circle's diameter, the radius is half of the diagonal:

x * \sqrt(2) / 2 = radius

We can now use the formula for the area of a circle to calculate x:

\(\pi * radius2 = area\)

\(\Pi * (x * sqrt(2) / 2)2 = 56\)

\(56 = pi * (x^2 / 2)\)

\(x^2 = 112 / pi\)

Step-by-step explanation:

If on a turn, the player moves forward the number of spaces equal to the first number rolled and then moves backward the number of spaces equal to the second number rolled. Then the probability that a player ends up 2 spaces ahead of where he started on a turn is 11%.

To end up 2 spaces ahead of where the player started, the number of spaces forward should be more than the number of spaces backward by 2.

⇒ First number - Second number = 2

All satisfied outcomes = (3,1), (4,2), (5,3) and (6,4).

Total possible outcomes = 36(6 outcomes for the first roll multiplied by 6 outcomes for the second roll)

\(Probability = \frac{All \ satisfied \ outcomes}{Total \ possible \ outcomes} = \frac{4}{36} = \frac{1}{9}\)

So this inequality is of the form
x ≤ 2

We can eliminate answer choices 2 and 4 which has y≤ 2

That leaves only the first and third choices

The smallest number a such that A + BB is regular for all B > a can be determined by finding the eigenvalues of the matrix A. The value of a will be greater than or equal to the largest eigenvalue of A.

A matrix A is regular if it is non-singular, meaning it has a non-zero determinant. We can consider the expression A + BB as a sum of two matrices. To ensure A + BB is regular for all B > a, we need to find the smallest value of a such that A + BB remains non-singular. One way to check for singularity is by examining the eigenvalues of the matrix A. If the eigenvalues of A are all positive, it means that A is positive definite and A + BB will remain non-singular for all B. In this case, the smallest number a can be taken as zero. However, if A has negative eigenvalues, we need to choose a value of a greater than or equal to the absolute value of the largest eigenvalue of A. This ensures that A + BB remains non-singular for all B > a.

Answer:

D) y = -5x + 5

Step-by-step explanation:

If two lines are perpendicular to each other, they have opposite slopes.

The first line is y = 1/5x + 5. Its slope is 1/5. A line parallel/perpendicular to this one will have a slope of -5.

Plug this value (#) into your standard point-slope equation of y = mx + b.

y = -5x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (2, -5). Plug in the x and y values into the x and y of the standard equation.

-5 = -5(2) + b

To find b, multiply the slope and the input of x (2)

-5 = -10 + b

Now, add 10 to both sides to isolate b.

5 = b

Plug this into your standard equation.

y = -5x + 5

This equation is parallel/perpendicular to your given equation (y = 1/5x + 5) and contains point (2, -5)
