A right rectangular prism is sliced in a way such that the plane passes through the prism at a slant. what is the resulting cross section?

Answers

Answer 1

The resulting cross section of the prism will be a parallelogram.

When a right rectangular prism is sliced in a way such that the plane passes through the prism at a slant, the resulting cross section is a parallelogram. This is because the intersection of a plane and a rectangular prism that is not parallel to any of its faces is always a parallelogram.

The shape and size of the parallelogram will depend on the orientation of the plane and the dimensions of the prism. Since the prism is a right rectangular prism, the opposite faces are parallel and congruent, and so are the opposite edges of the parallelogram cross section.

find all possible values of , if any, for which the matrix is not diagonalizable. if there are no such values, write none.

Answers

We have three linearly independent eigenvectors, the matrix A is diagonalizable for all values of λ.  .If there are no such values, the answer would be "none."

To determine if a matrix is diagonalizable, we need to find the eigenvectors and eigenvalues of the matrix. If there are enough linearly independent eigenvectors, then the matrix is diagonalizable.

If we let A be the given matrix, then we can find the eigenvalues by solving the characteristic equation det(A-λI) = 0, where I is the identity matrix. This gives us:

det(A-λI) = (4-λ)(3-λ)(2-λ) = 0

So the eigenvalues are λ = 4, λ = 3, and λ = 2.

To find the eigenvectors, we need to solve the equation (A-λI)x = 0 for each eigenvalue. This gives us the following:

For λ = 4, we have:

(A-4I)x = \begin{pmatrix} 0 & 1 & 1 \\ 0 & 0 & 0 \\ 0 & 0 & 1 \end{pmatrix} \begin{pmatrix} x_1 \\ x_2 \\ x_3 \end{pmatrix} = \begin{pmatrix} 0 \\ 0 \\ 0 \end{pmatrix}

Solving this system of equations gives us the eigenvector x = \begin{pmatrix} 1 \\ 0 \\ 0 \end{pmatrix}

For λ = 3, we have:

(A-3I)x = \begin{pmatrix} 1 & 1 & 1 \\ 0 & 1 & 0 \\ 0 & 0 & 0 \end{pmatrix} \begin{pmatrix} x_1 \\ x_2 \\ x_3 \end{pmatrix} = \begin{pmatrix} 0 \\ 0 \\ 0 \end{pmatrix}

Solving this system of equations gives us the eigenvectors x = \begin{pmatrix} -1 \\ 0 \\ 1 \end{pmatrix} and x = \begin{pmatrix} -1 \\ 1 \\ 0 \end{pmatrix}

For λ = 2, we have:

(A-2I)x = \begin{pmatrix} 2 & 1 & 1 \\ 0 & 1 & 0 \\ 0 & 0 & 2 \end{pmatrix} \begin{pmatrix} x_1 \\ x_2 \\ x_3 \end{pmatrix} = \begin{pmatrix} 0 \\ 0 \\ 0 \end{pmatrix}

Solving this system of equations gives us the eigenvector x = \begin{pmatrix} -1 \\ 0 \\ 1/2 \end{pmatrix}

Since we have three linearly independent eigenvectors, the matrix A is diagonalizable for all values of λ. Therefore, the answer is none.

Set up the triple integral of an arbitrary continuous function f(x, y, z) in cylindrical or spherical coordinates over the solid shown. Graph Graph Description The xy-coordinate plane is given. A solid in the first octant is formed by a cylinder of radius 1 centered on the z axis bounded above by z = 2. SITE f(x, y, z) dV = JO ] dz dr de

Answers

1. For ρ (distance from the z-axis), the limits of integration will be from 0 to 1, since the cylinder has a radius of 1.
2. For z (height), the limits of integration will be from 0 to 2, as the cylinder is bounded above by z=2.
Now, we can set up the triple integral using the conversion factor for cylindrical coordinates, which is ρ:
∫(0 to π/2) ∫(0 to 1) ∫(0 to 2) f(ρ, φ, z) * ρ dV = ∫(0 to π/2) ∫(0 to 1) ∫(0 to 2) f(ρ, φ, z) * ρ dz dρ dφ

To set up the triple integral of an arbitrary continuous function f(x, y, z) in cylindrical coordinates over the given solid, we first need to determine the limits of integration for each variable.

Since the solid is in the first octant, we know that x, y, and z are all non-negative.

In cylindrical coordinates, we have:

- x = r cos(theta)
- y = r sin(theta)
- z = z

The solid is a cylinder of radius 1 centered on the z-axis, so we have:

- r <= 1
- 0 <= theta <= 2pi
- 0 <= z <= 2

Therefore, the triple integral in cylindrical coordinates is:

∫∫∫ f(r cos(theta), r sin(theta), z) r dz dr d(theta)

with limits of integration:

- 0 <= r <= 1
- 0 <= theta <= 2pi
- 0 <= z <= 2

Note that we include the factor of r in the integrand because the volume element in cylindrical coordinates is r dz dr d(theta).

In spherical coordinates, we have:

- x = rho sin(phi) cos(theta)
- y = rho sin(phi) sin(theta)
- z = rho cos(phi)

where rho is the distance from the origin to the point (x, y, z), phi is the angle between the positive z-axis and the vector (x, y, z), and theta is the angle between the positive x-axis and the projection of (x, y, z) onto the xy-plane.

To determine the limits of integration, we need to consider the intersection of the solid with the sphere of radius rho. If rho <= 1, then the solid is completely contained within the sphere, so the limits of integration are:

- 0 <= rho <= 1
- 0 <= phi <= pi/2
- 0 <= theta <= 2pi

If rho > 1, then the solid intersects the sphere at z = 2, which gives us:

- 1 <= rho <= 2
- 0 <= phi <= pi/2
- 0 <= theta <= 2pi

Therefore, the triple integral in spherical coordinates is:

∫∫∫ f(rho sin(phi) cos(theta), rho sin(phi) sin(theta), rho cos(phi)) rho^2 sin(phi) d(phi) d(theta) d(rho)

with limits of integration:

- 0 <= rho <= 1, 0 <= phi <= pi/2
- 0 <= theta <= 2pi
- 1 <= rho <= 2, pi/2 <= phi <= arccos(1/rho)
- 0 <= theta <= 2pi

Note that we include the factor of rho^2 sin(phi) in the integrand because the volume element in spherical coordinates is rho^2 sin(phi) d(phi) d(theta) d(rho).

Find the volume of the solid by subtracting two volumes, the solid enclosed by the parabolic cylinders y=1−x2,y=x2−1 and the planes x+y+z=2,3x+3y−z+14=0.
Integration:
Application of integration:
(1) it is applied to determine the area beneath the curve.
(2) it is applied to determine the volume of a revolving solid.
(3) it is used to find the work done by a variable force.

Answers

To find the volume of the solid, we first need to sketch the region enclosed by the two parabolic cylinders and the two planes.

The two parabolic cylinders intersect at the points (-1,0,0) and (1,0,0), and the planes intersect at the point (1,-2,3).

Next, we need to find the limits of integration for x, y, and z. We can see that the region is symmetric about the yz-plane, so we only need to consider the positive values of x.

The parabolic cylinders have a common vertex at the origin and open downwards, so the limits of integration for y are -x^2+1 and x^2-1.

The planes have a common line of intersection, which is parallel to the vector <3,3,-1>. We can use this information to find the limits of integration for z.

The plane 3x+3y-z+14=0 intersects the yz-plane at y=(-14/3), and we can find the corresponding value of x using the equation 2=x+y+z. This gives us x=(-20/3).

The plane x+y+z=2 intersects the yz-plane at y=2-x, which gives us x=0.

Therefore, the limits of integration for x are 0 to (-20/3). The limits of integration for y are -x^2+1 to x^2-1. The limits of integration for z are given by the planes 3x+3y-z+14=0 and x+y+z=2.

Using the formula for the volume of a solid obtained by subtracting two volumes, we have:

V = ∭[2-x-y] dV - ∭[3x+3y+14] dV

where the first integral is taken over the region enclosed by the parabolic cylinders and the second plane, and the second integral is taken over the region enclosed by the two planes.

We can evaluate these integrals using the limits of integration we found above. The integrals will involve iterated integrals of the form ∫∫∫ f(x,y,z) dz dy dx.

The final answer for the volume of the solid is the difference between the two integrals.

Answers

To generate a 3-distinct letter code from the letters {A, B, C, D, E, F}, there are 6 choices for the first letter, 5 for the second letter, and 4 for the third letter. So, there are 6 × 5 × 4 = 120 different 3-distinct-letters codes.

For a 3-distinct letter code starting with the letter E, there are 1 choice for the first letter (E), 5 for the second letter, and 4 for the third letter. So, there are 1 × 5 × 4 = 20 different 3-distinct-letters codes that start with the letter E.

To generate a 4-distinct letter code from the letters {A, B, C, D, E, F} when the order does not matter, you need to find the number of ways to choose 4 letters from the 6 available. This can be calculated using combinations, represented as C(n, r) or "n choose r", where n is the total number of items, and r is the number of items to choose.

On average, Bentley drinks 3/5 of an 8-ounce glass of water in 3/4 of an hour. How many glasses of water does he drink in one hour?​

Answers

Answer: 0.8

Step-by-step explanation:

To solve the problem, we need to figure out how much water Bentley can drink in one hour. We can start by finding out how much water he drinks in one minute:

3/4 hour = 45 minutes

3/5 of an 8-ounce glass of water in 45 minutes = (3/5) x (8) x (1/45) = 0.1067 ounces per minute

Now we can find out how much water Bentley drinks in one hour:

0.1067 ounces per minute x 60 minutes = 6.4 ounces per hour

Since Bentley drinks 8 ounces of water in a full glass, he drinks:

6.4 ounces per hour ÷ 8 ounces per glass = 0.8 glasses of water in one hour

Therefore, Bentley drinks 0.8 glasses of water in one hour.

A boy is pushing a 50 kg box with the force F but the box is not moving. (10 min)30° F=20a) what type of friction is acting on this box. Why? b) What is the direction of friction force? Why? c) draw the Free body diagram d) calculate the amount of friction force. e) Calculate the coefficient of friction between box and floor.

Answers

The type of friction acting on the box is static friction. This is because the box is not moving, and static friction is the force that opposes motion when an object is at rest.

The direction of the friction force is opposite to the direction of the force applied by the boy. This is because friction always acts in the opposite direction to the applied force, to prevent the object from moving.

The free body diagram for the box would include the force of gravity acting downwards (50 kg x 9.8 m/s² = 490 N), the force applied by the boy (20 N at an angle of 30°), and the static friction force acting in the opposite direction to the applied force.

To calculate the amount of friction force, we can use the formula F_friction = F_applied x coefficient of friction. Since the box is not moving, the friction force is equal in magnitude to the applied force. Therefore, F_friction = 20 N.

To calculate the coefficient of friction, we can use the formula coefficient of friction = F_friction / F_normal. The normal force is equal in magnitude to the force of gravity, which is 490 N. Therefore, coefficient of friction = 20 N / 490 N = 0.041.

Suppose parametric equations for the line segment between (6,8) and (2,-1) have the form: x = a + bt y = c + dt If the parametric curve starts at (6,8) when t = 0 and ends at (2,-1) at t = 1, then find a,b,c, and d.

Answers

the parametric equations for the line segment are: x = 6 - 4t, y = 8 - 9t

To find the values of a, b, c, and d, we can use the following system of equations:

a + b(0) = 6  (when t = 0, x = 6)
c + d(0) = 8  (when t = 0, y = 8)
a + b(1) = 2  (when t = 1, x = 2)
c + d(1) = -1 (when t = 1, y = -1)

Simplifying each equation:

a = 6
c = 8
a + b = 2
c + d = -1

Substituting the values of a and c in the last two equations:

6 + b = 2
8 + d = -1

Solving for b and d:

b = -4
d = -9

Therefore, the parametric equations for the line segment between (6,8) and (2,-1) are:

x = 6 - 4t
y = 8 - 9t
To find the parametric equations for the line segment between (6,8) and (2,-1), we can use the given information:

x = a + bt
y = c + dt

When t = 0, the point is (6,8):
6 = a + b(0) => a = 6
8 = c + d(0) => c = 8

When t = 1, the point is (2,-1):
2 = a + b => 2 = 6 + b => b = -4
-1 = c + d => -1 = 8 + d => d = -9

So the parametric equations for the line segment are:

x = 6 - 4t
y = 8 - 9t

A basis for the subspace is {1, [tex]x^2[/tex]}, and the dimension of the subspace is 2.

a. To find a basis for the subspace {a(1 + x) + b(x + x^2) : a, b ∈ R} of P2, we need to find a set of vectors that are linearly independent and span the subspace. We can rewrite the polynomials in the form a + bx + cx^2 and then look for a linearly independent set.

If we set a = 1 and b = 0, we get the polynomial 1 + x, which is in the subspace. If we set a = 0 and b = 1, we get the polynomial x + x^2, which is also in the subspace. These two polynomials are linearly independent since neither is a scalar multiple of the other.

Therefore, a basis for the subspace is {1 + x, x + x^2}, and the dimension of the subspace is 2.

b. To find a basis for the subspace {(a + b(x + x^2)) : a, b ∈ R} of P2, we again need to find a set of vectors that are linearly independent and span the subspace. We can rewrite the polynomials in the form a + bx + cx^2 and then look for a linearly independent set.

If we set b = 0, we get the polynomial a, which is in the subspace. If we set a = 0 and b = 1, we get the polynomial x + x^2, which is also in the subspace. These two polynomials are linearly independent since neither is a scalar multiple of the other.

Therefore, a basis for the subspace is {1, x + x^2}, and the dimension of the subspace is 2.

c. To find a basis for the subspace {p(x) : p(1) = 0}, we need to find a set of polynomials that satisfy the given condition and span the subspace.

A polynomial p(x) that satisfies p(1) = 0 must have a factor of (x - 1). Therefore, we can write any polynomial in the subspace as p(x) = (x - 1)q(x), where q(x) is a polynomial of degree 1 or 0.

If we set q(x) = 1, we get the polynomial x - 1, which is in the subspace. If we set q(x) = 0, we get the zero polynomial, which is also in the subspace. These two polynomials are linearly independent since neither is a scalar multiple of the other.

Therefore, a basis for the subspace is {x - 1}, and the dimension of the subspace is 1.

d. To find a basis for the subspace {p(x) : p(x) = p(-x)}, we need to find a set of polynomials that satisfy the given condition and span the subspace.

A polynomial p(x) that satisfies p(x) = p(-x) must be an even function. Therefore, we can write any polynomial in the subspace as p(x) = a + bx^2, where a and b are constants.

If we set a = 1 and b = 0, we get the polynomial 1, which is in the subspace. If we set a = 0 and b = 1, we get the polynomial x^2, which is also in the subspace. These two polynomials are linearly independent since neither is a scalar multiple of the other.

After the first marble is drawn, there are a total of 16 marbles left in the bag, of which 11 are blue. Therefore, the probability that the first marble is blue is 11/16. After the first marble is drawn, there are 15 marbles left in the bag, of which 10 are blue. Therefore, the probability that the second marble is blue, given that the first marble is blue, is 10/15 or 2/3. To find the probability that both marbles are blue, we multiply these probabilities:

(11/16) * (2/3) = 22/48

suppose manufacturers change the size of compact disks so that they are made of the same material and have the same thickness as a current disk but have one third of the diameter. part a by what factor will the moment of inertia change? by what factor will the moment of inertia change? 13 19 127 181

Answers

Manufacturers change the size of compact disks so that they are made of the same material and have the same thickness as a current disk but have one third of the diameter, the moment of inertia will change by a factor of 1/9 or approximately 0.111.

The moment of inertia of a disk is proportional to the square of its radius (I = (1/2)mr^2). If the diameter of the new compact disk is one-third of the diameter of the current disk, then its radius will be one-sixth of the radius of the current disk (r_new = r_current/3). Therefore, the moment of inertia of the new compact disk will decrease by a factor of (1/6)^2 = 1/36, or 19.

Given that the new compact disk has one-third of the diameter of the current disk, the moment of inertia (I) will change as a function of the radius (r) squared. Since the diameter is halved, the radius is also one-third, and the moment of inertia is given by the formula I = k * r^2, where k is a constant.

When we reduce the radius to one-third (r/3), the new moment of inertia (I') can be calculated as:

I' = k * (r/3)^2
I' = k * (r^2/9)

To find the factor by which the moment of inertia has changed, we need to divide the new moment of inertia (I') by the original moment of inertia (I):

Factor = I'/I = (k * r^2/9) / (k * r^2) = 1/9

So, the moment of inertia will change by a factor of 1/9 or approximately 0.111.

Jim Corporation pays its cumulative preferred stockholders $1.60 per share. Jim has 10,000 shares of preferred and 65,000 shares of common. In 2013, 2014, and 2015, due to slowdowns in the economy, Jim paid no dividends. Now in 2016, the board of directors decided to pay out $550,000 in dividends.
How much of the $550,000 does each class of stock receive as dividends?
Dividends
Preferred stock $
Common stock $

Answers

The preferred stockholders are entitled to receive their dividend of $1.60 per share, regardless of whether or not Jim Corporation was able to pay it in the previous years.

Therefore, the total dividend amount for the preferred stockholders is:

10,000 shares x $1.60 per share = $16,000

To determine how much each class of stock receives in dividends, we need to subtract the total preferred stock dividend from the total dividend amount of $550,000:

$550,000 - $16,000 = $534,000

This remaining amount is the dividend available for the common stockholders. To calculate how much each common stockholder will receive, we need to divide this amount by the total number of common shares:

$534,000 ÷ 65,000 shares = $8.22 per share

Therefore, each class of stock receives the following dividends:

Preferred stock: $16,000
Common stock: $8.22 per share

Jim Corporation's cumulative preferred stockholders receive $1.60 per share. There are 10,000 shares of preferred stock, so the total annual preferred dividend is $1.60 x 10,000 = $16,000.

Since the preferred dividends were not paid in 2013, 2014, and 2015, the company owes the preferred stockholders a total of $16,000 x 3 = $48,000 in dividends.

In 2016, the board of directors decided to pay out $550,000 in dividends. First, the preferred stockholders will receive their overdue dividends of $48,000. After paying the preferred dividends, there will be $550,000 - $48,000 = $502,000 left for distribution.

Next, the preferred stockholders will receive their 2016 dividends of $16,000, leaving $502,000 - $16,000 = $486,000 for common stockholders.

So, the preferred stock receives $48,000 (past due) + $16,000 (current) = $64,000 in dividends, and the common stock receives $486,000 in dividends.

Dividends:
Preferred stock: $64,000
Common stock: $486,000

a gym believes that by doing its 45-minute exercise workout each day for a month, a person can lose more than 5 pounds. which statistical method would be best to use in this situation?

Answers

In this situation, the best statistical method to use would be a hypothesis test, specifically a one-sample t-test. This test will help determine if the average weight loss after following the gym's 45-minute workout routine for a month is significantly greater than 5 pounds.

In this situation, the best statistical method to use would be a hypothesis test. The gym's belief that their workout can lead to weight loss greater than 5 pounds can be tested by setting up a null hypothesis (the workout does not lead to weight loss greater than 5 pounds) and an alternative hypothesis (the workout does lead to weight loss greater than 5 pounds). The gym can then collect data on weight loss from participants who complete the workout for a month and use statistical analysis to determine if there is enough evidence to reject the null hypothesis and support the alternative hypothesis.

If a sphere and a cone have the same radii r and the cone has a height of 4, find the ratio of the volume of the sphere to the volume of the cone.

Answers

The ratio of the volume of the sphere to the volume of the cone is r.

We are given that;

Radius= r

Height of the cone= 4

Now,

To find the ratio of the volume of the sphere to the volume of the cone, we need to divide the formula for the volume of the sphere by the formula for the volume of the cone. We get:

Ratio = (4/3 πr3) / (1/3 πr2h)

Simplifying, we get:

Ratio = 4r / h

Since we are given that the cone has a height of 4, we can substitute h = 4 in the formula. We get:

Ratio = 4r / 4

Simplifying further, we get:

Ratio = r

This means that the ratio of the volume of the sphere to the volume of the cone is equal to the radius of both shapes.

Therefore, by the volume of cone the answer will be r.

Answers

Linear function would better model the data because as x increases, the y values change additively. The common difference or slope of the function is of about 11000.

How to classify the functions?

A function is classified as exponential if when the input variable is changed by one, the output variable is multiplied by a constant.

A function is classified as linear if when the input variable is changed by one, the output variable is increased/decreased by a constant.

The differences for this problem are given as follows:

71446 - 60529 = 10917.82451 - 71446 = 11005.93445 - 82451 = 10994.

If you cat in at a fist-food restaurant, most of the soda machines are self-serving. If you finish your drink, you can go back and fill up your cup as many times as you want. A loenl fast-food restaurant manager is concemed that people are taking advantage of filling up their drink and that the restaurant is losing money as a result. He selected a random sample of 90 customers who got a drink and are eating in the restaurant. He found that 19 of those customers are filling up more than 3 times. (a) Construct and interpret a 95 percent confidence interval for the proportion of all customers who, when ondering a drink and cating in the restaurant, will fill up their cup more than 3 times. (b) The manger measured if a customer filled up more than 3 times because that is when the restaurant will start to lose money on the drink. It will cost the restaurant

Answers

(a) To construct a 95% confidence interval for the proportion of all customers who fill up their cup more than 3 times, we can use the formula:

CI = p ± z*√((p(1-p))/n)

where pis the sample proportion, z is the z-score corresponding to the confidence level (95% corresponds to a z-score of 1.96), and n is the sample size.

In this case, we have p= 19/90 = 0.2111. Plugging in the values, we get:

CI = 0.2111 ± 1.96*√((0.2111(1-0.2111))/90)

CI = (0.1084, 0.3138)

Interpreting this interval, we can say that we are 95% confident that the true proportion of all customers who fill up their cup more than 3 times when ordering a drink and eating in the restaurant falls between 10.84% and 31.38%.

(b) To calculate the minimum number of times a customer must fill up their cup for the restaurant to start losing money on the drink, we need to know the cost per drink and the profit margin on each drink. Let's assume that the cost per drink is $0.25 and the profit margin is 75% (i.e., the restaurant makes $0.75 for every $1.00 in sales).

If a customer fills up their cup more than 3 times, they are essentially getting more than 4 drinks for the price of one. So, if the cost per drink is $0.25 and the customer pays $1.00 for the drink, the restaurant is losing $0.75 for every extra drink that the customer gets. Therefore, the minimum number of times a customer must fill up their cup for the restaurant to start losing money is:

$1.00 ÷ $0.75 = 1.33

In other words, if a customer fills up their cup more than 1.33 times, the restaurant is losing money on the drink.

She discusses the role of the Canadian Dominion government and the very strict law the miners had to follow. Then answer the question using evidence from the text to support your thinking.A Woman Who Went to Alaskaby Mary Kellogg Sullivan, 1902[3] The Canadian Dominion government is very oppressive. Mining laws are very arbitrary and strictly enforced. A person wishing to prospect for gold must first procure a miners license, paying ten dollars for it. If anything is discovered, and he wishes to locate a claim, he visits the recorders office, states his business, and is told to call again. In the meantime, men are sent to examine the locality and if anything of value is found, the man wishing to record the claim is told that it is already located. The officials seize it. The man has no way of ascertaining if the land was properly located, and so had no redress. If the claim is thought to be poor, he can locate it by the payment of a fifteen dollar fee.One half of all mining land is reserved for the crown, a quarter or more is gobbled by corrupt officials, and a meager share left for the daring miners who, by braving hardship and death, develop the mines and open up the country. [5] Anyone going into the country has no right to cut wood for any purpose, or to kill any game or catch any fish, without a license for which a fee of ten dollars must be paid. With such a license it is unlawful to sell a stick of wood for any purpose, or a pound of fish or game. This law is strictly enforced. To do anything, one must have a special permit, and for every such permit he must pay roundly.It is a well-known fact that many claims on Eldorado, Hunker, and Bonanza Creeks have turned out hundreds of thousands of dollars. One pan of gravel on Eldorado Creek yielded $2,100. Charley Anderson, on Eldorado, panned out $700 in three hours. T.S. Lippy is said to have paid the Canadian government $65,000 in royalties for the year 1898 and Clarence Berry about the same.When a man is compelled to pay one thousand dollars out of every ten thousand he digs from the ground, he will boast little of large clean-ups; and for this reason it is hard to estimate the real amount of gold extracted from the Klondike mines.
