Answers

Answer 1

To solve the triangle with angle B = 65° 45', side c = 32 m, and side a = 70 m, we can use the Law of Sines.

The Law of Sines states that for any triangle, the ratio of the length of a side to the sine of the angle opposite that side is constant.

We can use the Law of Sines to find the length of side b:

sin(B) / b = sin(A) / a

sin(65° 45') / b = sin(A) / 70

To find the length of side b, we rearrange the equation:

b = (sin(65° 45') * 70) / sin(A)

Now, we need to find angle A. Since the sum of angles in a triangle is 180°, we can find angle A using:

A = 180° - B - C

A = 180° - 65° 45' - 90°

Now, we can substitute the given values into the equations:

A ≈ 24° 15'

Finally, we can substitute the values of angle A and side a into the equation to find the length of side b:

b = (sin(65° 45') * 70) / sin(24° 15')

b ≈ 48 m

Therefore, the length of side b is approximately 48 m and the measure of angle A is approximately 24° 15'.

Michelle has $8 and wants to buy a combination of dog food to feed at least two dogs at the animal shelter. A serving of dry food costs $1, and a serving of wet food costs $3. This system of inequalities models the scenario: x + 3y ≤ 8 x + y ≥ 2 Part A: Describe the graph of the system of inequalities, including shading and the types of lines graphed. Provide a description of the solution set. (4 points) Part B: Is the point (8, 2) included in the solution area for the system? Justify your answer mathematically. (3 points) Part C: Choose a point in the solution set and interpret what it means in terms of the real-world context. (3 points)

Answers

Part A: The shaded region represents the feasible region where both inequalities are satisfied simultaneously. It is below the line x + 3y = 8 and above the line x + y = 2.

Part B: The point (8, 2) is not included in the solution area.

Part C: The point (3, 1) represents one feasible solution that meets the constraints of the problem.

Part A: The graph of the system of inequalities consists of two lines and a shaded region. The line x + 3y = 8 is a solid line because it includes the equality symbol, indicating that points on the line are included in the solution set. The line x + y = 2 is also a solid line. The shaded region represents the feasible region where both inequalities are satisfied simultaneously. It is below the line x + 3y = 8 and above the line x + y = 2.

Part B: To determine if the point (8, 2) is included in the solution area, we substitute the x and y values into the inequalities:

8 + 3(2) ≤ 8

8 + 6 ≤ 8

14 ≤ 8 (False)

Since the inequality is not satisfied, the point (8, 2) is not included in the solution area.

Part C: Let's choose a point in the solution set, such as (3, 1). This point satisfies both inequalities: x + 3y ≤ 8 and x + y ≥ 2. In the context of the real-world scenario, this means that Michelle can buy 3 servings of dry food (x = 3) and 1 serving of wet food (y = 1) with her $8 budget. This combination of dog food allows her to feed at least two dogs at the animal shelter while staying within her budget. The point (3, 1) represents one feasible solution that meets the constraints of the problem.

solve the system u=2x-3y, v=x+5y for x and y in terms of u and v. then find the value of the jacobian

Answers

the Jacobian matrix J for the system is: J = [ 1/2 0 ] [ -1/13 2/13 ]

To solve the system of equations:

u = 2x - 3y,

v = x + 5y,

We can use the method of substitution.

1. Solve the first equation for x in terms of u and y:

  u = 2x - 3y

  Rearrange the equation:

  2x = u + 3y

  Divide both sides by 2:

  x = (u + 3y) / 2

2. Substitute the expression for x in the second equation:

  v = x + 5y

  Replace x with (u + 3y) / 2:

  v = (u + 3y) / 2 + 5y

  Simplify:

  v = (u + 3y + 10y) / 2

  v = (u + 13y) / 2

Now we have x = (u + 3y) / 2 and y = (2v - u) / 13.

To find the Jacobian, we need to compute the partial derivatives of x and y with respect to u and v.

Partial derivative of x with respect to u:

∂x/∂u = 1/2

Partial derivative of x with respect to v:

∂x/∂v = 0

Partial derivative of y with respect to u:

∂y/∂u = -1/13

Partial derivative of y with respect to v:

∂y/∂v = 2/13

The Jacobian matrix J is given by:

J = [ ∂x/∂u   ∂x/∂v ]

   [ ∂y/∂u   ∂y/∂v ]

Substituting the partial derivatives:

J = [ 1/2   0 ]

   [ -1/13   2/13 ]

Therefore, the Jacobian matrix J for the system is:

J = [ 1/2   0 ]

   [ -1/13   2/13 ]

Answers

To find the constants m and b in the linear function f(x) = mx + b, we can use the given conditions f(7) = 9 and a slope of -3.

The value of f(7) represents the y-coordinate of the point on the line when x = 7. So, substituting x = 7 into the equation, we get 9 = 7m + b.

The slope of a linear function is given by the coefficient of x, which in this case is -3. So, we have m = -3.

Now, we can substitute the value of m into the equation obtained from f(7). We get 9 = 7(-3) + b, which simplifies to 9 = -21 + b.

Solving for b, we find b = 30.

Therefore, the constants for the linear function f(x) = mx + b that satisfy the given conditions are m = -3 and b = 30.

Answers

Answer:

1) Kansas

2) X = 2

3) Y = 6

Step-by-step explanation:

1) To determine the state where you would find yourself at the halfway point between Fairfield, California (-10, 1), and Montgomery, Alabama (5, -3), we need to find the coordinates of the halfway point.

The coordinates of the halfway point can be found by taking the average of the x-coordinates and the average of the y-coordinates.

Average x-coordinate = (-10 + 5) / 2 = -5/2 = -2.5

Average y-coordinate = (1 + (-3)) / 2 = -2 / 2 = -1

Therefore, the coordinates of the halfway point are approximately (-2.5, -1).

Using these coordinates, we can determine the state by referring to a map.

Based on the approximate coordinates, the halfway point falls within the state of Kansas.

2) To find the x-coordinate of the endpoint of the line segment with one endpoint at (10, 12) and a midpoint at (6, 9), we can use the midpoint formula.

The midpoint formula states that the coordinates of the midpoint between two points (x₁, y₁) and (x₂, y₂) are given by:

Midpoint = ((x₁ + x₂) / 2, (y₁ + y₂) / 2)

We are given the coordinates of the midpoint (6, 9) and one endpoint (10, 12). Let's denote the x-coordinate of the other endpoint as x.

Using the midpoint formula, we can set up the following equation:

((10 + x) / 2, (12 + y) / 2) = (6, 9)

To find the x-coordinate of the endpoint, we can equate the x-values:

(10 + x) / 2 = 6

Simplifying the equation:

10 + x = 12

x = 12 - 10

x = 2

Therefore, the x-coordinate of the endpoint of the line segment is 2.

3) To find the y-coordinate of the endpoint of the line segment with one endpoint at (10, 12) and a midpoint at (6, 9), we can use the midpoint formula.

The midpoint formula states that the coordinates of the midpoint between two points (x₁, y₁) and (x₂, y₂) are given by:

Midpoint = ((x₁ + x₂) / 2, (y₁ + y₂) / 2)

We are given the coordinates of the midpoint (6, 9) and one endpoint (10, 12). Let's denote the y-coordinate of the other endpoint as y.

Using the midpoint formula, we can set up the following equation:

((10 + x) / 2, (12 + y) / 2) = (6, 9)

To find the y-coordinate of the endpoint, we can equate the y-values:

(12 + y) / 2 = 9

Simplifying the equation:

12 + y = 18

y = 18 - 12

y = 6

Therefore, the y-coordinate of the endpoint of the line segment is 6.

when the second hand moves from halfway between the 1 and the 2 to 4/5 of the way from the 1 to the 2 what is the measure of the arc

Answers

The second hand moves 6 degrees in one second, it will take it: 294/6 = 49 seconds to move from halfway between 1 and 2 to 4/5 of the way from 1 to 2.

The measure of the arc is 144 degrees.

When the second hand of the clock moves from halfway between the 1 and the 2 to 4/5 of the way from the 1 to the 2, it moves a total of 144 degrees.

This can be calculated as follows: The second hand of a clock completes one full revolution every 60 seconds or 1 minute.

This means that in 1 second, it moves 360/60

= 6 degrees.

To find the measure of the arc when the second hand moves from halfway between the 1 and the 2 to 4/5 of the way from the 1 to the 2, we need to find the difference between the two positions in degrees.

The position halfway between the 1 and the 2 is 1.5 on the clock face.

This is equivalent to 45 degrees (since the clock face is divided into 12 hours, each hour marking is 30 degrees apart, so halfway between 1 and 2 is 30+15 = 45 degrees).

4/5 of the way from the 1 to the 2 is 4/5 x 30 = 24 degrees from the 1 mark.

Therefore, the total angle between halfway between 1 and 2 and 4/5 of the way from 1 to 2 is:

24 + (360 - 45)

= 339 degrees.

However, we need to find the difference between these two positions, not the total angle.

Therefore, we need to subtract the position of the second hand at halfway between 1 and 2 from the position at 4/5 of the way from 1 to 2:

339 - 45

= 294 degrees.

Since the second hand moves 6 degrees in one second, it will take it:

294/6 = 49 seconds to move from halfway between 1 and 2 to 4/5 of the way from 1 to 2.

The initial amount a is 1250 and the rate of decay r is 0.865 (86.5%). When t = 3, the function h(t) = 1250(0.865)3 = 587.356. Rounded to the nearest tenth, the answer is 587.4.

To solve this exercise, you need to use the equation

h(t) = a(r)^t,

Where a is the initial amount and r is the rate of decay.

In this example,

a = 1250 and r = 0.865 (86.5%).

Plugging in t = 3 into the equation gives

h(t) = 1250(0.865)^3 = 587.356.

To round this to the nearest tenth, you need to look at the number to the right of the decimal point, which is the 6 in 587.356. Since the 6 is 5 or greater, you need to round the 587.356 up to 587.4.

Using the Pythagorean Theorem, we can find the length of side VW:

VW² = UW² - VU²

VW² = 72² - 97²

VW² = 5184 - 9409

VW² = 4225

VW = 65

A) greater than E0
B) equal to E0
C) less than E0
D) cannot be determined without knowing F

Answers

When horizontal and vertical forces of magnitude F are exerted on the block as it slides down the frictionless ramp, the mechanical energy of the Earth-block system at the bottom will be less than E0.

The mechanical energy of a system is the sum of its kinetic energy and potential energy. In this case, as the block slides down the ramp, its potential energy decreases and is converted into kinetic energy. The presence of the horizontal and vertical forces implies that work is done on the block, adding additional energy to the system. This extra energy increases the block's kinetic energy, resulting in a higher speed at the bottom of the ramp. Since kinetic energy is directly proportional to the square of the velocity, a higher speed means a greater kinetic energy.

Therefore, with the additional forces applied, the mechanical energy of the Earth-block system at the bottom will be greater than the mechanical energy E0, making option A) "greater than E0" the correct choice.

If the answer is 8.55%, enter 8.55)

Answers

The risk premium for Idaho Bakery stock is 8.97%.To calculate the risk premium for Idaho Bakery stock, we need to subtract the risk-free rate from the expected return on the market.

The risk premium represents the additional return expected from an investment above the risk-free rate to compensate for the additional risk.

The formula for the risk premium is:

Risk Premium = Expected Market Return - Risk-Free Rate

Given:

Beta (β) = 2.71

Expected Return on Market = 11.09%

Risk-Free Rate = 4.65%

Inflation = 2.53%

To calculate the risk premium, we first need to adjust the Risk-Free Rate for inflation:

Real Risk-Free Rate = Risk-Free Rate - Inflation

Real Risk-Free Rate = 4.65% - 2.53% = 2.12%

Now, we can calculate the Risk Premium:

Risk Premium = Expected Market Return - Real Risk-Free Rate

Risk Premium = 11.09% - 2.12% = 8.97%

Therefore, the risk premium for Idaho Bakery stock is 8.97%.

To build your own capacitor, you have cut your sheets of wax paper and aluminum foil to a length of L = 0.8 m and you are rolling them on a pipe of diameter D = 5 cm. What is the number of turns? -n = 2.6 -n = 20.4 -n = 5.1 -n=10.2

Answers

The number of turns in the capacitor is approximately 5.1.

How we get the number of turns (n)?

The number of turns in the capacitor can be calculated using the formula:

n = L / [π(D + t)]

where L is the length of the sheets, D is the diameter of the pipe, and t is the thickness of the sheets.

Using the provided values, we can calculate the number of turns as follows:

L = 0.8 mD = 5 cm = 0.05 mt = negligible (assumed to be much smaller than D)

n = 0.8 / [π(0.05)]

= 5.092 (rounded to one decimal place)

In this problem, we are asked to calculate the number of turns in a capacitor made from sheets of wax paper and aluminum foil that are rolled on a pipe of diameter 5 cm. We are given the length of the sheets as 0.8 m.

To calculate the number of turns, we can use the formula that relates the length of the sheets, diameter of the pipe, and thickness of the sheets to the number of turns in the capacitor. Assuming the thickness of the sheets is much smaller than the diameter of the pipe, we can ignore the thickness in the calculation.

Using the provided values and this formula, we find that the number of turns is approximately 5.1. This means that the sheets need to be rolled around the pipe about 5 times to create the capacitor.

A recent survey in the company found that employees have low levels of job satisfaction and motivation, although the basic wage levels (minimum wage) are considered particularly satisfactory compared to the competition. At the same time, an important finding of this research was the fact that a large part of junior and medium-sized managers and production workers stated that their jobs are characterized by low autonomy (inability to plan and plan work, inability to make decisions on relevant issues, etc.), a limited variety of tasks, and a lack of an integrated performance evaluation system that will provide detailed information on the results and critical behaviors to successfully perform their work. As a possible consequence of these factors, the last year has seen an increase in the rate of departures while at the same time inability to attract new capable workers.At the same time, the company is implementing a series of technological changes by automating a large part of its production process and adopting a new business resource management information system (ERP system). In these initiatives, too, however, there is significant inertia with the limited presence and lack of support from the top management, the lack of training programs in the new processes and systems, and the inability to communicate the benefits of the changes to the executives and employees involved. Also, and as a potential result of these shortcomings, many employees appear reluctant to use the new systems, preferring previous processes that continue to create a sense of job security and protection of their role and specialized experience within the business.Identify and analyze the characteristics and types of pay that a new pay plan may include with the aim of enhancing job satisfaction and motivation of the company's employees.
