Answer:

C

Step-by-step explanation:

The correct answers for the given data are (a) b = 6, (b) arg(z - 9) = -π/4, and (c) ||w/w|| = 1.

(a) To determine z/w, we first need to express z and w in terms of their real and imaginary parts. Given 2 = 3 + 6i, we can rewrite it as z = 3 + 6i. Similarly, w = a + bi. Now, let's calculate z/w:

z/w = (3 + 6i)/(a + bi)

To make z/w real, the imaginary part of the denominator should cancel out the imaginary part of the numerator. This means 6/a = 6i/b. Simplifying further, we get ab = 6a + 6bi. Since a and b are real numbers, the only way for the equation to hold is if b = 6 and a = 1. Therefore, b = 6.

(b) To determine arg(z - 9), we need to subtract 9 from z = 3 + 6i:

z - 9 = (3 + 6i) - 9 = -6 + 6i

The argument (or angle) of -6 + 6i can be calculated as:

arg(-6 + 6i) = arctan(6/(-6)) = arctan(-1) = -π/4

(c) To determine ||w/w|| (the magnitude of w divided by the magnitude of w), we need to find the magnitude of w. Given w = a + bi, the magnitude of w is given by:

||w|| = √(a^2 + b^2)

Now, substituting a = 1 and b = 6 (from part a):

||w|| = √(1^2 + 6^2) = √37

Therefore, ||w/w|| = ||w||/||w|| = 1.

Answer:

Cosec <F = 73/55

Step-by-step explanation:

In ΔEFG, the measure of ∠G=90°, GF = 48, EG = 55, and FE = 73. What ratio represents the cosecant of ∠F?

First you must know that;

Cosecant <F = 1/sin<F

Given

∠G=90°, GF = 48, EG = 55, and FE = 73.

ED ,= hyp = 73

EG = opp = 55*side facing <F

Using DOH CAH TOA

Sin theta = opp/hyp

Sin <F= 55/73

Reciprocate both sides

1/sinF = 73/55

Cosec <F = 73/55

The transaction would affect the company's equity accounts by increasing contributed capital by $14,400 and earned capital by $19,200. The correct answer is option C.

Equity accounts are a component of the balance sheet that represents the net worth of a business. The equity accounts include contributed capital and earned capital. Contributed capital, also referred to as paid-in capital, is the value of cash or other assets contributed to a company by investors in exchange for shares of ownership in the company. Contributed capital represents the long-term financial interests of owners in the business.

Earned capital is the amount of money that a business earns through its operations. It is also referred to as retained earnings. The difference between a business's assets and liabilities is its equity. It represents the total value of the assets that a company owns after all liabilities have been settled. According to the question, the owner contributed cash of $14,400 and a delivery truck with a fair value of $19,200 to the company. This transaction will increase contributed capital by $14,400 (the cash contribution) and increase earned capital by $19,200 (the delivery truck contribution).Therefore, option C: Increase contributed capital by $14,400 and earned capital by $19,200 is the correct answer.

Answer:

x = 12

z = 101

Step-by-step explanation:

Hello There!

First lets find z

Well the angle that has a measure of 79 degrees and angle z are supplementary angles meaning that the sum of the two is 180

So we can find the missing angle by subtract the given angle (79 in this case) from 180

180 - 79 = 101 so z = 101

Now lets find x

The angle that has a measure of 79 degrees and the angle labeled (6x+7) are vertical angles

If you didn't know vertical angles are congruent

That being said lets create an equation to solve for x

79 = 6x + 7

now we solve for x

step 1 subtract 7 from each side by

7 - 7 cancels out

79 - 7 = 72

now we have 72 = 6x

step 2 divide each side by 6

72/6=12

6x/6=x

we're left with x = 12

Between the years 1970 and 1976, what percentage change in the rate of exchange occurred in the German mark relative to the United States dollar (to the nearest percent)?

45 %

The percentage change in the rate of exchange occurred in the German mark relative to the United States dollar is 45%

From the chart (table), we have the following rates in Germany:

The percentage change is then calculated using:

Percentage change= (Final - Initial)/Initial * 100%

This gives

Percentage change= (39.74 - 27.42)/27.42* 100%

Evaluate the quotient

Percentage change= 0.45* 100%

Evaluate the product

The borrower would need to make payments of approximately $943.57 per year to pay off the loan in 5 years.

To determine the payment rate required to pay off the loan in 5 years, we can use the continuous compound interest formula:

A = P * [tex]e^{(rt)[/tex],

where A is the final amount, P is the initial principal, e is the base of the natural logarithm (approximately 2.71828), r is the annual interest rate, and t is the time in years.

In this case, the initial principal is $6600, the annual interest rate is 10%, and the time is 5 years. We want to find the payment rate, so let's set A equal to zero, indicating that the loan is fully paid off:

0 = 6600 * [tex]e^{(0.10 * 5)[/tex]- k * 5,

Simplifying the equation, we have:

[tex]e^{(0.5)[/tex] = k / 6600.

Now, we can solve for k by multiplying both sides of the equation by 6600:

k = 6600 * [tex]e^{(0.5)[/tex],

Using a calculator or software, we find that k is approximately $943.57 per year.

The lengths of the sides of the triangle ABC are √14, √26, and √26, and the triangle is neither a right triangle nor an isosceles triangle.

To find the lengths of the sides of the triangle with vertices A(3, 4, 1), B(0, 6, 2), and C(3, 5, 6), we can use the distance formula.

The distance formula between two points (x₁, y₁, z₁) and (x₂, y₂, z₂) in three-dimensional space is given by:

d = √((x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²)

Let's calculate the lengths of the sides of the triangle:

Side AB:

d₁ = √((0 - 3)² + (6 - 4)² + (2 - 1)²)

= √((-3)² + 2² + 1²)

= √(9 + 4 + 1)

= √14

Side BC:

d₂ = √((3 - 0)² + (5 - 6)² + (6 - 2)²)

= √(3² + (-1)² + 4²)

= √(9 + 1 + 16)

= √26

Side AC:

d₃ = √((3 - 3)² + (5 - 4)² + (6 - 1)²)

= √(0² + 1² + 5²)

= √(0 + 1 + 25)

= √26

Now, let's analyze the triangle based on the lengths of its sides:

Since all three sides have different lengths (√14, √26, and √26), the triangle is neither an isosceles triangle (which has at least two sides of equal length) nor a right triangle (which satisfies the Pythagorean theorem).

In summary, the lengths of the sides of the triangle ABC are √14, √26, and √26, and the triangle is neither a right triangle nor an isosceles triangle.

Using the Successive Over-Relaxation (SOR) method with a relaxation factor of w = 1.2 and a tolerance of TOL = 10^-3 in the l2 norm, the linear system of equations can be solved iteratively. The solution will converge to the desired tolerance level.

The SOR method is an iterative technique used to solve linear systems of equations. It requires an initial guess for the solution and iteratively updates the values until the desired tolerance is reached.

To apply the SOR method, the given linear system can be rewritten as a matrix equation: AX = B, where A is the coefficient matrix, X is the solution vector, and B is the constant vector. The system can be solved by iterating through the equations and updating the values of X until convergence is achieved.

In this case, the SOR method is performed with a relaxation factor of w = 1.2, which helps to accelerate convergence. The tolerance is set to TOL = 10^-3, indicating the desired level of accuracy.

The SOR algorithm is then applied iteratively until the solution converges within the specified tolerance. The updated values of X are calculated using the SOR formula, and the process is repeated until the difference between consecutive iterations falls below the tolerance level.

By following this iterative process with the given parameters, the SOR method will yield the solution to the linear system of equations.

Step-by-step explanation:

Let us assume that he would received the first payment after t years

So

The following formula should be used

PV = P ÷ (1 + r)^t + P ÷ (1 + r)^t+5

$2,606 = $2,500 ÷ (1 + 0.05)^t + $2,500 ÷ (1 + 0.05)^t + 5

$2,606 = $2,500 ÷ 1.05^t (1 + 1 ÷ (1.05)^5)

1.05^t = $2,500 ÷ $2,606 (1.7835) = 1.71098

The magnetic field using the unit vector notation B = Bx i= [(μ₀ / 4π) * (q * (-1.0 x 10⁷ m/s) / 10^-16 m²)] i.

To determine the strength and direction of the magnetic field at the (1 cm, 0 cm, 0 cm) position caused by a moving proton, we can use the formula for the magnetic field produced by a moving charge:

B = (μ₀ / 4π) * (qv × r / r³)

where B is the magnetic field, μ₀ is the permeability of free space (constant), q is the charge of the proton, v is its velocity, × denotes the cross product, r is the position vector, and r³ represents the magnitude cubed of the position vector.

Given information:

u = -1.0 x 10⁷ m/s (velocity of the proton)

Position vector r = 1 cm i

Let's calculate the magnetic field at the given position:

First, we convert the position vector from centimeters to meters:

r = (1 cm, 0 cm, 0 cm) = (0.01 m, 0 m, 0 m)

Next, we substitute the values into the formula and simplify:

B = (μ₀ / 4π) * (qv × r / r³)

= (μ₀ / 4π) * (q * (-1.0 x 10⁷ m/s) × (0.01 m i) / (0.01 m)³)

= (μ₀ / 4π) * (q * (-1.0 x 10⁷ m/s) × (0.01 m i) / 0.000001 m³)

= (μ₀ / 4π) * (q * (-1.0 x 10⁷ m/s) × (0.01 m i) / 10^-18 m³)

= (μ₀ / 4π) * (q * (-1.0 x 10⁷ m/s) / 10^-16 m²) i

Now, we can express the magnetic field using the unit vector notation:

B = Bx i

= [(μ₀ / 4π) * (q * (-1.0 x 10⁷ m/s) / 10^-16 m²)] i

where Bx represents the magnitude of the magnetic field in the x-direction.

Please note that the direction of the magnetic field will depend on the orientation of the velocity vector of the proton.
