The second and third image will be congruent to the pre-image. The solution has been obtained by applying the concept of transformations.

What is transformation?

Any action that moves a polygon or other two-dimensional object on a plane or coordinate system is referred to as a transformation.

Pre-image or "inverse image" refers to the two-dimensional shape that exists before any change. The transformed shape is represented by the image.

1. This is not congruent because both the coordinates are dilated and after dilation the size of the image is not the same as of original figure.

2. This is congruent because there is only translation which means it is same as the original figure but the position is different.

3. This is congruent because only translation has taken place which means it is same as the original figure but the position is different.

4. This is not congruent because one coordinate i.e. x has been dilated and after dilation the size of the image is not the same as of original figure.

Hence, second and third are congruent to the pre-image.

The shape is a triangular prism and the volume of the shape is 45 ft^3.

A triangular prism is a 3-dimensional shape with two parallel triangular bases and three rectangular sides connecting the bases. It has six faces and nine edges in total.

The volume of the triangular prism is;

V = 1/2(b * h * l)

b = base

h = height

l = length

V = 0.5 (6 * 3 * 5)

By applying standard equation of a circle concept, it can be concluded that the equation that defines the circle is  (x + 4)² + (y - 3)² = 50.

Circle is a collection of points on a plane line that are all the same distance (the radius) from a given point (the center).

Standard equation of a circle can be written as:

(x - h)² + (y - k)² = r²   , where:

(h,k) = center of the circle

r = radius

We know that the radius of the circle has endpoints (-4,3) and (1,-2), which means that one of these points is the center of the circle.

Since we know that its center is in the second quadrant, we can conclude that (-4,3) is the center.

Now we can substitute these values into the equation:

   (x - h)² + (y - k)² = r²

(1 - (-4))² + (-2 - 3)² = r²

              5² + (-5)² = r²

                25 + 25 = r²

                        50 = r²

As we know the r, now we can have the standard equation of the circle:

   (x - h)² + (y - k)² = r²

(x - (-4))² + (y - 3)² = 50

 (x + 4)² + (y - 3)² = 50

Thus the equation that defines the circle is  (x + 4)² + (y - 3)² = 50.

A triangle is a three-sided polygon that is sometimes (but not always) referred to as the trigon. Every triangle has three sides and three angles, which may or may not be the same. A triangle is a three-sided polygon with three edges and three vertices in geometry. The total of a triangle's interior angles equals 180 degrees, which is its most essential feature. This is known as the angle sum property of a triangle.

Here,

To translate a triangle, you need to add the same value to each x-coordinate and each y-coordinate. In this case, the translation moves each point 2 units to the left and 3 units down, so the new coordinates of Y and Z would be:

Y'(3 - 2, -1 - 3) = Y'(1, -4)

Z'(0 - 2, 2 - 3) = Z'(-2, -1)

When x = 0 and y = 0, we get 0 = -1a + 4b + c + d, so d = 0. When x = 1 and y = -2, we get -2 = -1a + 4b + c, so c = -1. When x = 2 and y = -26, we get -26 = -1a + 4b, so b = 4. Finally, when x = 3 and y = -54, we get -54 = -1a, so a = -1.

A country's population in 1995 was 23 million. In 2001 it was 25 million, the population in 2013 using the exponential growth formula in 2013 will be around 30 million.

For this problem, we have the final population P, the starting population A, and the time passed t.

We still need to determine the value of the growth factor k.

This can be done using the information for the years 1995 and 2001.

In this case, A will be 23 million (the population in 1995), P will be 25 million (the population in 2001), and t will be 6 years (the number of years between 1995 and2001):

[tex]P=Ae^{kt}[/tex]

[tex]25=23e^{k 6}[/tex]

[tex]e^{6k} =\frac{25}{23}[/tex]

[tex]k = \frac{ln(25) - ln(23)}{6}[/tex]

k = 0.013897

Now, let's use this information to determine P in 2013.

A will still be 23 million, but t will be 18 years.

[tex]P= 23e^{0.013897*18} \\P= 23e^{0.250146} \\P=23 * 1.28421\\P=29.5368\\[/tex]

Answer:

62

Step-by-step explanation:

Use the Law of Sines: sinA/a = sinB/b = sinC/c, where A, B, and C are the angles and a, b, and c are the sidelengths opposite of their corresponding angles.

If angle G = 66 and angle H = 30, then angle F = 180-66-30 = 84 degrees.

Therefore sin84/67 = sin66/g.

Multiple both sides by g and divde by sin84/7 to get

g = sin66/(sin84/67) = 61.5... which is about 62 inches.

The value of x in the system of equations is: x = 11.2.

The value of x can be found by solving the system of equations.

One method is to substitute the value of x from one equation into the other equation, solve for y, then use the value of y to find x.

Starting with the second equation: 5x + 2y = 48

Solve for y: y = (48 - 5x) / 2

Now substitute this expression for y into the first equation:

-5x - 12((48 - 5x) / 2) = -8

-5x - 6(48 - 5x) = -8

-5x - 288 + 30x = -8

25x - 288 = - 8

25x = -8 + 288

25x = 280

x = 280/25

x = 11.2

(bonus) prove the equation ∃x(a(x) ∧ ¬b(x)) ∀x(a(x) −→ c(x)) ∴ ∃x(c(x) ∧ ¬b(x))

Proof by Contradiction:Assume that ∃x(c(x) ∧ ¬b(x)) is false.

Therefore, we can conclude that ∀x(c(x) ∧ ¬b(x)) is true.

This implies that for all x, either c(x) is false or b(x) is true.

But, from our assumption, we know that ∃x(a(x) ∧ ¬b(x)) is true.

Therefore, there must exist an x such that a(x) is true and b(x) is false.

Since a(x) is true, we can conclude from ∀x(a(x) −→ c(x)) that c(x) must also be true.

But this is a contradiction since we previously assumed that the equation ∀x(c(x) ∧ ¬b(x)) is true, which implies that c(x) must be false.

The required measure of an angle is 73 degrees which supplement is 253.

The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.

The supplement of an angle is equal to 180 degrees minus the angle.

So if we call the angle "x", we can set up an equation as follows:

2x + (180 - x) = 253

Using unitary method, turkey's temperature after 55 minutes is 120.815° Also, it will take approximately 68 minutes for the turkey to cool down to 105°.

Now, According to the question:

What is unitary method?

The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.

Reduction in temperature after 30 minutes = 185° - 150° = 35°

Reduction in temperature after 1 minute = 35/30 = 1.167°

Reduction in temperature after 55 minutes = 55 × 1.167 = 64.185°

Temperature after 50 minutes = 185° - 64.185° = 120.815°

Decrease in temperature when the turkey has cooled down to 105° = 185° - 105° = 80°

Time taken by the turkey to cool down 80° = 80/1.167 = 68.55 minutes.

The number of complete days that 4 packs of treats will last, we need to determine the total number of packs each day and divide it into the total number of packs Mrs. Mills has bought.

Let's call the number of days the treats will last "d".

Then, the number of packs Fluff eats in "d" days is d * (1/6 of a pack per day) = (1/6)d.

Similarly, the number of packs Tigger eats in "d" days is d * (1/5 of a pack per day) = (1/5)d.

The total number of packs they eat in "d" days is (1/6)d + (1/5)d = (11/30)d.

Since Mrs. Mills has bought 4 packs, we have 4 = (11/30)d.

Finally, solving for "d", we have d = (30/11) * 4 = 120/11 days.

Since "d" must be a whole number, we round down to get 10 complete days that the 4 packs of treats will last.
