Step-by-step explanation:

The rule that best represents the dilation applied to Circle | to create Circle || is the scale factor. The scale factor determines the ratio of corresponding lengths between the original figure (Circle |) and the dilated figure (Circle ||).

In a dilation, all lengths in the original figure are multiplied by the scale factor to obtain the corresponding lengths in the dilated figure. This includes the radii of the circles.

For example, if the scale factor is 2, it means that every length in the original figure is doubled in the dilated figure. If the scale factor is 1/2, it means that every length is halved. The scale factor can be greater than 1, less than 1 (but greater than 0), or even negative, indicating a reflection.

In the context of the given scenario, since the origin is the center of dilation, the scale factor determines how the distances from the origin to any point on Circle | are scaled to obtain the corresponding distances on Circle ||.

By apply the cylindrical shells method proved that the volume of the cone is V = [tex]\frac{1}{3}[/tex]πr²h.

Given that,

Consider an upright cone that was generated by rotating the triangular plane region shown in the image about the y-axis. It has a base radius of r and a height of h.

We have to apply the cylindrical shells method to confirm that the volume of the cone is V = [tex]\frac{1}{3}[/tex]πr²h

We know that,

By using the disk method,

V = [tex]\int\limits^b_a {\pi [f(x)]^2} \, dx[/tex]

Differentiating on both the sides,

dV = π[f(x)]² dx

Integrating on both sides with the limits 0 to h

[tex]\int\limits^h_0 { dV }= \int\limits^h_0 {\pi[f(x)]^2 }dx[/tex]

V = [tex]\int\limits^h_0 {\pi \frac{r^2x^2}{h^2} } \, dx[/tex]

V = [tex]\pi \frac{r^2}{h^2}\int\limits^h_0 {x^2 } \, dx[/tex]

V = [tex]\pi \frac{r^2}{h^2}[\frac{x^3}{3}]^h_0[/tex]

V = [tex]\pi \frac{r^2}{h^2}[\frac{h^3}{3}][/tex]

V = [tex]\frac{1}{3}[/tex]πr²h

Step-by-step explanation:

x = 5

The value of x in the given angle is 5.

A circle is a particular type of ellipse in mathematics or geometry where the eccentricity is zero and the two foci are congruent. A circle is also known as the location of points that are evenly spaced apart from the centre. The radius of a circle is measured from the centre to the edge.

Labelling the figure,

We have,

Measure of complete angle of circle = 360 degree

∠ABC = 360 - (81 + 74)

          =  205 degree

Now from figure,

∠APE = (205 - 81 )/2

          = 62 degree

Since we know that,

∠APE = 17x - 23

Therefore,

17x - 23 = 62

17x = 85

  x = 5 degree,

An eigenvector corresponding to λ₂ = 2 - i is v₂ = [-1, 1].

To find the eigenvalues of matrix A, we need to solve the characteristic equation det(A - λI) = 0, where I is the identity matrix.

Let's compute the determinant:

det(A - λI) = |[2 - λ -1]|

|[ 1 2 - λ]|

Expanding along the first row, we have:

(2 - λ)(2 - λ) - (-1)(1) = (2 - λ)² + 1 = λ² - 4λ + 5 = 0

To solve this quadratic equation, we can use the quadratic formula:

λ = (-(-4) ± √((-4)² - 4(1)(5))) / (2(1))

= (4 ± √(16 - 20)) / 2

= (4 ± √(-4)) / 2

Since we are working over the complex numbers, the square root of -4 is √(-4) = 2i.

λ₁ = (4 + 2i) / 2 = 2 + i

λ₂ = (4 - 2i) / 2 = 2 - i

Now, let's find the eigenvectors corresponding to each eigenvalue.

For λ₁ = 2 + i, we solve the equation (A - (2 + i)I)v = 0:

[2 - (2 + i) -1] [x] [0]

[ 1 2 - (2 + i)] [y] = [0]

Simplifying, we have:

[0 -1 -1] [x] [0]

[ 1 0 - i] [y] = [0]

From the first equation, we have -x - y = 0, which implies x = -y.

Choosing y = 1, we have x = -1.

Therefore, an eigenvector corresponding to λ₁ = 2 + i is v₁ = [-1, 1].

For λ₂ = 2 - i, we solve the equation (A - (2 - i)I)v = 0:

[2 - (2 - i) -1] [x] [0]

[ 1 2 - (2 - i)] [y] = [0]

Simplifying, we have:

[0 -1 -1] [x] [0]

[ 1 0 i] [y] = [0]

From the first equation, we have -x - y = 0, which implies x = -y.

Choosing y = 1, we have x = -1.

In summary:

λ₁ = 2 + i has eigenspace span {[-1, 1]}

λ₂ = 2 - i has eigenspace span {[-1, 1]}

The statement in the question that needs to be proven is :C & F, then X-cef = G is G an open set in C and CnH+ 0 s G for each Hef

We will prove that (i) implies (ii) and (ii) implies (i).

Proof: (i) C & F, then X-cef = G is G an open set in C and CnH+ 0 s G for each Hef

Let X \ {C & F} = U, then U is open, since C & F is closed.

Let H be any point of U.

By hypothesis, there exists an open set G such that CnH+ 0 s G.

Let x in G. If x ∈ C & F, then x ∉ H, so x ∉ U.

Thus, G ⊆ C, and so G ∩ U = ∅.

Hence, U is open(ii) G is G an open set in C and CnH+ 0 s G for each Hef

Let x ∈ X-C & F.

Then x ∉ C & F, so x ∉ C.

Since C is closed, there exists a neighborhood G of x that is disjoint from C.

Let H be any point of X-C & F.

Then H ∈ G and so CnH+ 0 s G.

Thus, C & F is closed.

Therefore, X-C & F is open, since C & F is closed.

Thus, X-C & F = G.

Hence, (ii) implies (i).

If difference scores begin to pile up away from a sample mean difference score of Mp= 0, the null hypothesis will likely be rejected. So, correct option is B.

This suggests that there is a likely effect or relationship between the variables being compared.

Option b. The null hypothesis will likely be rejected is the correct statement in this scenario. When the observed differences are consistently far from zero, it implies that the null hypothesis, which assumes no significant difference or effect, is unlikely to be true.

Thus, based on the evidence provided by the data, we would reject the null hypothesis in favor of an alternative hypothesis that suggests the presence of a difference or effect.

The critical region refers to the region of extreme values that would lead to rejecting the null hypothesis. While the size of the critical region can vary depending on the chosen significance level, it does not directly indicate the likelihood of rejecting the null hypothesis in this context.

Similarly, the sample size (option c) does not provide information about the likelihood of rejecting the null hypothesis in this situation.

So, correct option is B.

B. 5x2 + 7x – 26

Step-by-step explanation:  keeping in mind that the area of a rectangle is simply width * length, if we get the area of the larger rectangle, and then subtract the area of the smaller rectangle, we're in effect making a hole in the larger rectangle's area and thus what's leftover is the shaded area.

.................................................................................................................................

Answer:

Area = 5x^2 +7x -26

Step-by-step explanation:

The area of the shaded region can be found if you substruct the small rectangle from the big one. The area of any rectangle is calculated if you multiply width and height.

In other words:

A_small = (x-3)(x-6) = x^2-9x +18

A_big = (2x+2)(3x-4) = 6x^2 -2x -8

A_big - A_small = (6x^2 -2x -8) - (x^2-9x +18)

= 6x^2 -2x -8 - x^2 + 9x -18

= 5x^2 +7x -26

Step-by-step explanation:

The general solution of the differential equation dy/dt + 4/ty = e raised to power of t/t raised to power of 3:

y = C * e raised to power of t * t raised to power of 4

where C is an arbitrary constant.

To find this solution, we can use the following steps:

First, we can factor out e raised to power of t/t raised to power 3 from the right-hand side of the equation. This gives us:

dy/dt + 4/ty = e raised to power t/t raised to power of 3 * (1/t)

Next, we can multiply both sides of the equation by ty to get:

dy + 4 = e raised to power of t/t raised to power of 2

Now, we can integrate both sides of the equation. This gives us:

y + 4t = C * e raised to power of t

Finally, we can solve for y to get the general solution:

y = C * e raised to power of t * t raised to power of 4

where C is an arbitrary constant.

The first step of the solution is to factor out e raised to power t/t raised to power of 3 from the right-hand side of the equation. This is possible because the derivative of e raised to power of t/t raised to power of 3 is e raised to power of t/t raised to power of 3 * (1/t).

The second step of the solution is to multiply both sides of the equation by ty to get dy + 4 = e raised to power of t/t raised to power of 2. This is possible because the derivative of ty is t + y.

The third step of the solution is to integrate both sides of the equation. This gives us y + 4t = C * e raised to power of t. This is possible because the integral of dy is y and the integral of e raised to power t/t raised to power of 2 is -2e raised to power of t/t + C.

The fourth step of the solution is to solve for y to get the general solution y = C * e raised to power t * t raised to power of 4. This is possible by dividing both sides of the equation by C * e raised to power of t.
