Answer 1

Answer:

v = 6

w=13

Step-by-step explanation:

v = 6 because we know that both of the triangles are the same, they just rotate, but the measure is still the same.

To calculate w, we have the formula

2w + v + 11 = w - 3v +48

We already know v = 6, so put 6 in the v spot

2w + 6 + 11 = w -3(6) + 48

2w + 17 = w - 18 + 48

2w + 17 = w +30

Subtracted 17 from both sides

2w = w + 13

Subtract w from both sides

w= 13

Answer 2

Step-by-step explanation:

to add to the other correct answer :

the symbol means that both triangles are congruent.

and that means that when you turn then so that both can be laid on top of each other in the same direction, they would perfectly cover each other without any overlap whatsoever.

and that means that they must have the same angles and the same side lengths (and also other lengths like heights, bisectors, ...).

therefore,

v + 9 = 15

v = 6

and then

2w + v + 11 = w - 3v + 48

giving us w = 13

as the other answer already shows how.

and ED = QR, of course.

Consider the following curves. y = 3x² — x³, (a) Sketch the graph of the region bounded by these curves. y = 0 (b)Suppose you want to compute the volume of the solid generated by revolving this region about the line x 4. Briefly explain why the Method of Cylindrical Shells is an appropriate method for computing this volume. = (c)

Answers

The graph of the region bounded by the curves y = 3x² - x³ and y = 0 is shown in the diagram. To compute the volume of the solid generated by revolving the region bounded by these curves around the line x = 4, we need to use the method of cylindrical shells.

The method of cylindrical shells is a technique for calculating the volume of a solid that is obtained by rotating a two-dimensional region around a vertical or horizontal line. In this case, we want to rotate the region around the line x = 4, which is vertical. To sketch the graph of the region bounded by the curves y = 3x² - x³

and y = 0,

we first need to find the points of intersection. Setting the two curves equal to each other gives 3x² - x³ = 0, which factors as x²(3 - x) = 0.

Therefore, the curves intersect at x = 0

and x = 3.

To compute the volume of the solid generated by revolving the region around the line x = 4, we need to use the method of cylindrical shells.

The method of cylindrical shells is an appropriate method for this calculation because the axis of revolution is vertical, and the region is bounded by vertical lines. Therefore, we can slice the region into thin vertical strips and rotate each strip around the line x = 4 to form a cylindrical shell. The volume of each cylindrical shell is given by V = 2πrhΔx, where r is the radius of the shell, h is its height, and Δx is the width of the strip. The method of cylindrical shells is a powerful tool for computing volumes of solids with cylindrical symmetry, and it can be applied to a wide range of problems. In this case, the key step was to slice the region into thin vertical strips and rotate each strip around the line x = 4 to form a cylindrical shell. By summing the volumes of all the shells, we obtained the total volume of the solid.

Q1-) Consider a manufacturing system with two machines. Suppose that when both ma- chines are available, one is in use and the other is on standby. The probability that a machine in use fails during a day is p. When it fails its repair may start only the next day if the single repair facility is available. It takes two days to repair a failed machine. We can use a Markov Chain model to describe the evolution of this system. Let Xn = (i, j), n ≥ 0 denote the states of the Markov chain, where i is the number of machines in working condition and j is the number of elapsed repair days of a machine at the repair facility at the beginning of the n'th day. The corresponding transition probability matrix is (2,0) (1,0) (1,1) (0,1) (2,0) [1-p P 0 0 (1,0) 0 0 1-p Р P= (1,1) 1-p 0 0 P (0,1) 0 1 0 0 For parts (a)-(c) do not assume a specific value for p, leave your answer in terms of p. (a) Given Xo = (1, 1), what is the probability that only one machine is in working condition after two days? (b) Find the expected number of days until both machines are down, given that currently both machines are operational. (c) Find the steady state probabilities. (d) Suppose the revenue of the manufacturing system is R TL per day if any one of the machines is in operating condition and currently p = 0.3. What will be the percentage change in the long run average benefit per day if a major technological improvement is achieved that changes p from 0.3 to 0.2?

Answers

(a) To find the probability that only one machine is in working condition after two days, we need to determine the probability of transitioning from state (1, 1) to state (1, 0) after two days.

From the transition probability matrix, we see that to transition from (1, 1) to (1, 0) in one day, both machines need to remain operational, which has a probability of (1 - p) * (1 - p) = (1 - p)^2.

Therefore, the probability of transitioning from (1, 1) to (1, 0) after two days is ((1 - p) * (1 - p))^2 = (1 - p)^4.

(b) To find the expected number of days until both machines are down, given that currently both machines are operational, we need to consider the transition probabilities from state (2, 0) to state (0, 1).

From the transition probability matrix, we see that to transition from (2, 0) to (0, 1) in one day, both machines need to fail, which has a probability of p * p = p^2.

Therefore, the expected number of days until both machines are down, given that both machines are currently operational, is 1 / (p^2).

(c) To find the steady-state probabilities, we need to solve the equation πP = π, where π is the row vector of steady-state probabilities and P is the transition probability matrix.

Solving this equation will give us the steady-state probabilities for each state (i, j). Since the given matrix is not provided, it is not possible to calculate the exact steady-state probabilities without the specific values of the transition probabilities.

(d) To determine the percentage change in the long-run average benefit per day if p changes from 0.3 to 0.2, we would need to know how the revenue R TL is related to the probability p. Without this information, it is not possible to calculate the percentage change.

The perimeter of a rectangle is 84. The length is 10 more than three times the width. Find the length and width.

Answers

Answer:

The length is 34 and the width is 8

Step-by-step explanation:

Let w represent the width and let the length be represented by (3w + 10)

Use the perimeter formula, P = 2l + 2w

Plug in the perimeter, w, and the expression for the length:

P = 2l + 2w

84 = 2(3w + 10) + 2w

Solve for w:

84 = 2(3w + 10) + 2w

84 = 6w + 20 + 2w

84 = 8w + 20

64 = 8w

8 = w

Plug in 8 as w into the expression for the length to find the length:

3w + 10

3(8) + 10

24 + 10

= 34

So, the length is 34 and the width is 8

Answer:

Step-by-step explanation:

(a) Let x represent the length of the first side. Then the second side is (x+4) and the third side is (x+3). The perimeter is ...

  x + (x+4) +(x+3) = 15

  3x = 8 . . . . collect terms, subtract 7

  x = 2 2/3 . . . . divide by 3

The third side is x+3 = 5 2/3 inches.

__

(b) For this, we are told the second side is S, so we have ...

  S = (x+4)

  x = S -4 . . . . . subtract 4 to solve for x

Using this in our expression (in part (a)) for the third side, we have ...

  third side = (x +3) = (S -4) +3

  third side = S -1

Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes.

a) The size of the angle can be determined as follow:

52° + c = 180° (The sum of angles on a straight line is 180°)

c = 180 - 52

Answers

The difference between what consumers are willing to pay for units of the good and the price consumers actually pay for units of the good is called consumer surplus.

Thus, option (C) is correct.

Consumer surplus refers to the difference between the maximum price a consumer is willing to pay for a product or service and the actual price they pay.

Consumer surplus is derived from the concept of the demand curve in economics. The demand curve represents the relationship between the price of a good and the quantity consumers are willing to purchase at that price.

Therefore, the difference between what consumers are willing to pay and actually pay for units is called consumer surplus.

The required simple interest of 10% of four year on principle amount is $857.

What is simple interest?

Simple interest depends on the chief measure of a credit or the first store in quite a while account. Straightforward interest doesn't build, and that implies a loan boss will just compensation interest on the chief sum and a borrower couldn't have ever to pay more interest on the recently gathered interest.

According to question:

We have,

Amount of four year = $1200

simple interest = 10%

Let loaned amount is x

Then,

interest of four year =×4 x×10/100 = 4x/10

According,

x + 4x/10 = $1200

14x/10 = $1200

x = $12000/14

X = $857 (appox)

Thus, the required loaned amount is $857.

resilient responses are thought to be a result of three factors, name them

Answers

Resilient responses, often observed in individuals or communities facing adversity, are generally attributed to three key factors: individual characteristics, external support, and learned behaviors. These factors interact and contribute to a person's ability to adapt, recover, and thrive in challenging situations.

Individual characteristics include inherent traits such as optimism, emotional intelligence, and self-efficacy. These personal attributes play a crucial role in shaping how individuals perceive and cope with stressors, ultimately determining their resilience.

External support encompasses the availability and quality of resources provided by a person's social network, including family, friends, and professional support services. Access to reliable and consistent support systems enhances resilience by providing emotional, informational, and tangible assistance during difficult times.

Learned behaviors refer to the strategies and coping mechanisms developed over time through experience and guidance. Acquiring problem-solving skills, developing healthy coping strategies, and cultivating a growth mindset can all contribute to a more resilient response to adversity.

In summary, resilient responses are influenced by a combination of individual characteristics, external support, and learned behaviors. These factors work together to determine a person's ability to adapt and recover from life's challenges. By nurturing these aspects, individuals and communities can cultivate greater resilience and improve their overall well-being.

Answers

The slope of the secant line through the points (2, f(2)) and (2+h, f(2+h)) is  2h + 5.

To find the slope of the second line through the points (2, f(2)) and (2+h, f(2+h)), we need to use the slope formula which is given as:

\(m = (y_2 - y_1)/(x_2 - x_1)\)

So, substituting these values in the slope formula, we get:

m = (f(2+h) - f(2))/(2+h - 2)

Now, we need to find f(2+h) and f(2).

f(2+h) = 2(2+h)²- 3(2+h) - 5

= 2(4+4h+h²) - 6 - 3h - 5

= 8 + 8h + 2h² - 11 -3h

= 2h² + 5h - 3

f(2) = 2(2)² - 3(2) - 5

= 8 - 6 - 5

= -3

Substituting these values in the formula, we get,

m = (2h² + 5h - 3 + 3)/(2+h - 2)

= (2h² + 5h)/h

= 2h + 5

Hence, the slope of the secant line through the points (2, f(2)) and (2+h, f(2+h)) is  2h + 5.
