Pls brainliest...

Answer: I think there is 1 : -8

Step-by-step explanation: It's because you're CUBE rooting a negative number, so the answer has to be negative, resulting in only 1 answer, as opposed to if you were square rooting.

The correct answer is E) Both A and C are true. In summary, the line integral jĚ.dr of a smooth, positive function f of two variables, where F = Vf, is positive for all smooth paths C and positive for all closed smooth paths C.

Explanation:

The line integral jĚ.dr represents the work done by the vector field F on a particle that moves along the path C. In this case, since F = Vf, we have jĚ.dr = VfĚ.dr. By the fundamental theorem of calculus for line integrals, we have:

jĚ.dr = VfĚ.dr = f(P) - f(Q)

where P and Q are the endpoints of the path C. Since f is positive everywhere, we have f(P) > f(Q), which implies that jĚ.dr is positive for all smooth paths C.

Moreover, since f is positive everywhere, we have f(P) > f(Q) for any two points P and Q on a closed path C. Therefore, jĚ.dr is positive for any closed smooth path C. This means that the vector field F is "circulation-preserving", meaning that the work done by F on a particle that moves around a closed loop is always positive.

In conclusion, both A and C are true, as jĚ.dr is positive for all smooth paths C and positive for all closed smooth paths C.

Answer:

38.2 ft

Step-by-step explanation:

The ladder, the ground, and the wall make a right triangle.

The wall is the opposite leg to the 63° angle.

The ladder is the hypotenuse.

Let x = length of the hypotenuse.

sin Θ = opp/hyp

sin 63° = 34 ft / x

x × sin 63° = 34 ft

x = 34 ft / sin 63°

x = 38.2 ft

1. 1430 people were surveyed.

2. 150 people like fish but not meat.

3. 330 people are vegetarians.

1. 650 (total who like meat) - 250 (who like meat but not fish) = 400 (who like both meat and fish)

Now, we know that 550 people don't like meat, and 480 people don't like fish. Since 400 people like both meat and fish, the total number of people surveyed is:

550 (don't like meat) + 480 (don't like fish) + 400 (like both meat and fish) = 1430

So, 1430 people were surveyed.

2. 550 (don't like meat) - 400 (like both meat and fish) = 150

So, 150 people like fish but not meat.

3. 480 (don't like fish) - 150 (like fish but not meat) = 330

So, 330 people are vegetarians.

In order to write formulae that give the evolution of the concentrations in terms of the extent of reaction, we need to use the stoichiometry of the reaction and the initial concentrations of the reactants.

Let's consider a generic reaction of the form:

a A + b B ⟶ c C + d D

where A and B are the reactants, C and D are the products, and a, b, c, and d are the stoichiometric coefficients. The extent of reaction, denoted by ξ, represents the amount of reaction that has occurred and is related to the change in the concentrations of the reactants and products by the stoichiometry of the reaction:

Δ[A] = -aξ

Δ[B] = -bξ

Δ[C] = cξ

Δ[D] = dξ

where Δ[X] is the change in concentration of species X. Using these relationships, we can write the evolution of the concentrations in terms of the extent of reaction as follows:

[A] = [A]0 - aξ

[B] = [B]0 - bξ

[C] = cξ

[D] = dξ

where [X]0 is the initial concentration of species X. These formulae give the concentrations of the reactants and products as a function of the extent of reaction ξ. Note that the concentrations of the reactants decrease as the reaction proceeds, while the concentrations of the products increase.

The solution to Laplace's equation for the bottom side of the plate is u(x, y) = ∑[n=1 to ∞] 4/(nπ sinh(nπ)) [1 - cos(nπ)] sinh(nπ(T-y)/T) sin(nπx/T)

Let's start with the left side of the plate, where u(0, y) = 1. Since this is a constant potential, the solution to Laplace's equation is simply u(x, y) = 1.

Next, let's consider the right side of the plate, where u(TT, y) = 1. Again, the solution to Laplace's equation is u(x, y) = 1.

Moving on to the top side of the plate, where u(x, 0) = 0. We can use separation of variables to find the solution to Laplace's equation in terms of a Fourier series:

u(x, y) = ∑[n=1 to ∞] Bn sin(nπx/T) [tex]e^{-n\pi y/T}[/tex]

where T is the length of the side, and Bn are constants that depend on the boundary conditions. Since u(x, 0) = 0, we have:

Bn = 2/T ∫[0 to T] 0 sin(nπx/T) dx = 0

Therefore, the solution to Laplace's equation for the top side of the plate is:

u(x, y) = 0

Finally, let's consider the bottom side of the plate, where u(x, 7) = 1. Using separation of variables again, we find:

u(x, y) = ∑[n=1 to ∞] An sinh(nπ(T-y)/T) sin(nπx/T)

where An are constants that depend on the boundary conditions. Since u(x, 7) = 1, we have:

An = 2/ sinh(nπ) ∫[0 to T] sin(nπx/T) dx

Using trigonometric identities, we can evaluate this integral and obtain:

An = 4/(nπ sinh(nπ)) [1 - cos(nπ)]

Now, we can add these four solutions together to obtain the solution for the entire plate:

u(x, y) = 1 + ∑[n=1 to ∞] 4/(nπ sinh(nπ)) [1 - cos(nπ)] sinh(nπ(T-y)/T) sin(nπx/T)

This is the solution to Laplace's equation for a square plate with the given boundary conditions.

(a) G = N; addition

To show that G = N (the set of natural numbers) under addition is a group, we need to verify the four group axioms:

Closure: For any a, b in N, a + b is also in N.

Associativity: For any a, b, c in N, (a + b) + c = a + (b + c).

Identity element: There exists an element 0 in N such that for any a in N, a + 0 = a.

Inverse element: For any a in N, there exists an element -a in N such that a + (-a) = 0.

Closure and associativity hold for addition on N, so we only need to verify the identity and inverse elements.

Identity element: The only possible identity element is 0, since adding any natural number to 0 gives that number. Thus, 0 is the identity element of (N, +).

Inverse element: For any a in N, there is no element -a in N such that a + (-a) = 0. Therefore, G = N under addition is not a group, because the inverse element axiom fails.

(b) G = R; a · b = a + b + 1

To show that G = R (the set of real numbers) under the given operation is a group, we need to verify the four group axioms:

Closure: For any a, b in R, a + b + 1 is also in R.

Associativity: For any a, b, c in R, (a + b + 1) + c = a + (b + c) + 1.

Identity element: There exists an element e in R such that for any a in R, a + e + 1 = a. Solving for e, we get e = -1, so -1 is the identity element of (R, ·).

Inverse element: For any a in R, there exists an element b in R such that a · b = e. Solving for b, we get b = -a - 2. Thus, for any a in R, -a - 2 is the inverse element of a.

Therefore, G = R under the given operation is a group.

The inverse of the matrix A is:

| -5  2 |

|   3 -1 |

To find the inverse of a matrix using row reduction, we can use the following algorithm:

1. Write the matrix A next to the identity matrix I, separated by a vertical line to obtain the augmented matrix [A|I].

2. Apply row operations to transform the left side of the augmented matrix into the identity matrix I. Perform the same row operations on the right side of the augmented matrix to obtain the inverse matrix A^-1.

3. If the left side of the augmented matrix cannot be transformed into I, then A does not have an inverse.

Let's apply this algorithm to find the inverse of the matrix A:

```

| 1  2 |

| 3  5 |

```

We first write the augmented matrix [A|I]:

```

| 1  2 | 1  0 |

| 3  5 | 0  1 |

```

Next, we perform row operations to transform the left side of the augmented matrix into I:

R2 - 3R1 -> R2

```

| 1  2 | 1   0 |

| 0 -1 | -3  1 |

```

-R2 -> R2

```

| 1  2 | 1    0 |

| 0  1 | 3   -1 |

```

-2R2 + R1 -> R1

```

| 1  0 | -5   2 |

| 0  1 | 3   -1 |

```

We have now transformed the left side of the augmented matrix into I, so the right side is the inverse matrix:

```

| -5  2 |

|  3 -1 |

The individual events of drawing and eating two red pieces of candy in a row from a bag are dependent. The probability of the second event is influenced by the outcome of the first event, since one red candy has already been removed from the bag.

The probability of drawing a red candy from the bag on the first attempt is 6/37. Once the first red candy has been drawn and eaten, there are now 5 red candies left in the bag out of 36 total candies. Therefore, the probability of drawing and eating a second red candy from the bag is now 5/36.

The probability of the combined event of drawing and eating two red candies in a row can be found by multiplying the probability of the first event by the probability of the second event, since the events are dependent:

P(drawing and eating two red candies in a row) = P(drawing a red candy on the first attempt) x P(drawing a red candy on the second attempt, given that a red candy was drawn on the first attempt)

P(drawing and eating two red candies in a row) = (6/37) x (5/36)

P(drawing and eating two red candies in a row) = 5/222

Therefore, the probability of drawing and eating two red candies in a row from the bag is 5/222 or approximately 0.0226.

Using the pair (10, 460) on the graph find the speed per hour:

Find the distance after 13 hours:

The matching choice is D.

The force of friction is equal to the centripetal force, which is given by the formula Fc = mv²/r, where m is the mass of the worker, v is the speed of the worker, and r is the radius of the circle. After plugging in the values, we get a force of friction of 55.97 N.

The problem requires us to calculate the force of friction necessary to keep the merry-go-round worker from falling off the platform. To solve this problem, we need to use the concept of centripetal force. Centripetal force is the force required to keep an object moving in a circular path. In this case, the force of friction is acting as the centripetal force to keep the worker moving in a circular path.

We are given the mass of the worker, which is 65 kg, and her speed, which is 4.1 m/s. We also know that the worker is standing 5.3 meters away from the center of the merry-go-round. To calculate the force of friction, we can use the formula for centripetal force, which is Fc = mv²/r, where Fc is the centripetal force, m is the mass of the worker, v is the speed of the worker, and r is the radius of the circle.

After substituting the given values, we get:

Fc = (65 kg)(4.1 m/s)²/5.3 m

Fc = 55.97 N

Therefore, the force of friction required to keep the worker from falling off the platform is 55.97 N.

To obtain the equivalent integral, we need to rewrite the original integral limits and order of integration.

Starting from the innermost integral, we have ∫x=0^(z) f(x,y,z)dy, where y varies from 0 to z.

Moving to the second integral, we now have ∫z=1^(0) ∫x=0^(z) f(x,y,z)dydx, where z varies from 1 to 0 and x varies from 0 to z.

The partial derivative of z with respect to s is $\frac{\partial z}{\partial s} = \frac{\partial f}{\partial x} r^3 + \frac{\partial f}{\partial y} 2re^{2s}$

The partial derivative of z with respect to s can be found using the chain rule of differentiation as follows:

$\frac{\partial z}{\partial s} = \frac{\partial z}{\partial x} \frac{\partial x}{\partial s} + \frac{\partial z}{\partial y} \frac{\partial y}{\partial s}$

Given that $x = r^3s$ and $y = re^{2s}$, we have:

$\frac{\partial x}{\partial s} = r^3$ and $\frac{\partial y}{\partial s} = 2re^{2s}$

Taking partial derivatives of z with respect to x and y:

$\frac{\partial z}{\partial x} = \frac{\partial f}{\partial x}$ and $\frac{\partial z}{\partial y} = \frac{\partial f}{\partial y}$

Hence, the partial derivative of z with respect to s is:

$\frac{\partial z}{\partial s} = \frac{\partial f}{\partial x} r^3 + \frac{\partial f}{\partial y} 2re^{2s}$

Answer:

"Then I stopped the machine, and saw about me again the old familiar laboratory, my tools, my appliances just as I had left them. I got off the thing very shakily and sat down upon my bench. For several minutes I trembled violently. Then I became calmer. Around me was my old workshop again, exactly as it had been. I might have slept there, and the whole thing have been a dream.

Step-by-step explanation:

Answer:

x = 0 and x = 4/3

Step 1:  First, we must find the derivative of f(x), noted by f'(x)

When you have a polynomial in the form x^n, we take the derivative of each polynomial using the following formula:

[tex]f'(x)=nx^n^-^1[/tex]

This means that the exponent becomes a coefficient and we subtract from the exponent.

We can do take the derivatives of x^3 and -2x^2 separately and combine them at the end:

x^3:

[tex]x^3\\3x^3^-^1\\3x^2[/tex]

-2x^2

[tex]-2x^2\\-2(2x^2^-^1)\\-4x[/tex]

Thus, f'(x) is 3x^2 - 4x

Step 2:  Critical points are found when f'(x) = 0 or when f'(x) = undefined.  There are no values for x which would make 3x^2 - 4x undefined, so we can set the function equal to 0 and solving will give us our critical points

We see that we can factor out x from 3x^2 - 4x to get

x(3x - 4) = 0

Now, we can set the two expressions equal to 0 to solve for x:

Setting x equal to 0:

x = 0

Setting 3x - 4 equal to 0:

3x - 4 = 0

3x = 4

x = 4/3

Therefore, the two critical points of the function are x = 0 and x = 4/3

To write the given expression as a single integral, we can apply the linearity property of integration, which states that the integral of the sum of two functions is equal to the sum of their integrals.

Using this property, we get:

a^2 f(x) dx - 5 + 3 f(x) dx / 2 - (-3 f(x) dx / 5)

Now, we can simplify each term by multiplying and dividing by appropriate constants to get a common denominator of 10:

= (2a^2 f(x) - 50) / 10 + (15 f(x) - 6 f(x)) / 10 + (30 f(x) - (-3) f(x)) / 10

= (2a^2 f(x) + 9 f(x) + 33 f(x) - 50) / 10

= (2a^2 + 42) / 10

Therefore, the given expression can be written as the single integral:

∫ [(2a^2 f(x) + 9 f(x) + 33 f(x) - 50) / 10] dx

which simplifies to:

(2a^2 + 42) / 10 ∫ f(x) dx

Answer: Around 2.46 cm.

Step-by-step explanation:

The volume for a cylinder is volume = πr^2 x h

Substitute the variables
158 = 3.14 x r^2 x 8.3

Simplify the right side (multiple 3.14 x 8.3) to get 158 = r^2 x 26.062

Divide both sides by 26.062 to get approximately 6.06 = r^2

To get rid of the exponent, take the square root of 6.06, which is around 2.46.

The surface area of the given prism is 386 square inches.

To find the surface area of a prism, we need to find the area of all its faces and add them up.

The given prism has a rectangular base with dimensions of 7 inches by 15 inches, and a height of 4 inches.

The two rectangular faces (front and back) have dimensions of 7 inches by 4 inches,

so each has an area of 7 x 4 = 28 square inches.

The two rectangular faces (sides) have dimensions of 15 inches by 4 inches,

so each has an area of 15 x 4 = 60 square inches.

The top and bottom faces are both rectangles with dimensions of 7 inches by 15 inches,

so each has an area of 7 x 15 = 105 square inches.

Therefore, the total surface area of the prism is:

2(28 sq in) + 2(60 sq in) + 2(105 sq in) = 56 sq in + 120 sq in + 210 sq in

                                                               = 386 sq in.

The density of the cube is 0.08343 grams per cubic centimeter

The side of cube is 8 inches

and, We know that :

The formula of Density is :

D = mass/ volume

The weight of a cube is 700 gm.

First, we convert the side inches into cm

For conversion, We have to multiply by 2.54

=> 8 × 2.54

=> 20.32cm

Now, For finding the density

We have to calculate the volume of cube :

Volume of cube = [tex](side)^3[/tex]

Volume of cube = 8390.18[tex]cm^3[/tex]

And, plug all the values in the formula of density.

Density = 700/8390.18[tex]cm^3[/tex]

Density = 0.08343 grams per cubic centimeter

Answer:

-infinity < x < infinity

Step-by-step explanation:

it has none.

Answer:

A

Step-by-step explanation:

[tex]\lim_{x \to -2} \frac{x^{2}-4 }{x+2} \\\lim_{x \to -2} \frac{(x+2)(x-2)}{x+2}\\ \lim_{x \to -2} x-2\\= -4[/tex]

Answer:

First answer choice

[tex]- 4[/tex]

Step-by-step explanation:

[tex]\lim _{x\to \:-2}\left(\dfrac{x^2-4}{x+2}\right)\\\\\\\mathrm{Simplify}\:\dfrac{x^2-4}{x+2}\\\\\\\mathrm{Factor}\:x^2-4:\quad (x + 2)(x - 2)\\\\\lim _{x\to \:-2}\left(\dfrac{x^2-4}{x+2}\right) \\\\= \lim _{x\to \:-2}\left(\dfrac{x+2)(x-2)}{x+2}\right)[/tex]

The x+2 common factor cancels out

[tex]= \lim _{x\to \:-2}\left(x-2\right)\\\\\text{Plug in the value x= -2}\\\\= -2 - 2\\= -4[/tex]
