Let's assume the original length of the rectangle is 'l' cm and the original width is 'w' cm. The area of the original rectangle is given as 48 cm^2. It seems there might be an error or inconsistency in the problem statement or calculation.

1. When both the length and width are increased by 4 cm, the area of the larger rectangle is increased by 12 cm^2. To find the length and width of the original rectangle, we can set up an equation and solve for the unknowns.

2. Let's start by considering the original rectangle with length 'l' cm and width 'w' cm. The area of a rectangle is calculated by multiplying its length and width, so the area of the original rectangle is given by A = l * w.

3. According to the problem, the area of the original rectangle is 48 cm^2. Therefore, we have the equation:

l * w = 48   ----(1)

4. Now, let's consider the larger rectangle, where both the length and width are increased by 4 cm. The new length would be 'l + 4' cm, and the new width would be 'w + 4' cm. The area of the larger rectangle is given by A' = (l + 4)(w + 4).

5. The problem states that the area of the larger rectangle is increased by 12 cm^2 compared to the original rectangle. Therefore, we can set up another equation:

(l + 4)(w + 4) = 48 + 12   ----(2)

6. We now have a system of two equations (equations 1 and 2) with two unknowns (l and w). To solve this system, we can substitute equation 1 into equation 2 and simplify:

(l + 4)(w + 4) = 48 + 12

lw + 4l + 4w + 16 = 60

lw + 4l + 4w = 44

7. Using equation 1, we can substitute lw with 48:

48 + 4l + 4w = 44

4l + 4w = 44 - 48

4l + 4w = -4

Dividing both sides by 4, we get:

l + w = -1

8. Since we are dealing with dimensions, the length and width cannot be negative. Therefore, it seems there might be an error or inconsistency in the problem statement or calculation. Please verify the given information to find a solution.

The  statement is d) Line segments E'F' and G'H' do not intersect and are the same distance apart as EF and GH.

The figure shows a pair of parallel line segments on a coordinate grid: Line segment GH runs from (-1, -1) to (3, -1), and line segment EF runs from (-1, -2) to (3, -2).

To determine the characteristics of line segments E'F' and G'H' after being translated 2 units to the right, we need to apply the translation to the endpoints of the original line segments.

Applying a translation of 2 units to the right:

Endpoint E: (-1, -2) + (2, 0) = (1, -2)

Endpoint F: (3, -2) + (2, 0) = (5, -2)

Endpoint G: (-1, -1) + (2, 0) = (1, -1)

Endpoint H: (3, -1) + (2, 0) = (5, -1)

Now, let's analyze the statements:

a) Line segments E'F' and G'H' do not intersect and are closer together than EF and GH.

  This statement is false. E'F' and G'H' do not intersect, but they are not closer together than EF and GH. They are actually farther apart.

b) Line segments E'F' and G'H' intersect at (-2, 0) and are two times farther apart than EF and GH.

  This statement is false. E'F' and G'H' do not intersect at (-2, 0). They have different coordinates for their endpoints.

c) Line segments E'F' and G'H' intersect at (0, -2) and are two times closer together than EF and GH.

  This statement is false. E'F' and G'H' do not intersect at (0, -2). They have different coordinates for their endpoints.

d) Line segments E'F' and G'H' do not intersect and are the same distance apart as EF and GH.

  This statement is true. E'F' and G'H' do not intersect, and they have the same distance between them as EF and GH.

Therefore, the correct statement is d) Line segments E'F' and G'H' do not intersect and are the same distance apart as EF and GH.

Given the figure, we have to find the value of y.Using the angle sum property of a quadrilateral, we know that the sum of angles in a quadrilateral is 360 degrees.

Therefore:

∠A + ∠B + ∠C + ∠D = 360°

We know that

∠A = 600°,

∠B = 120°, and

∠C = 100°

∠A + ∠B + ∠C + ∠D = 360°

600° + 120° + 100° + ∠D = 360°

820° + ∠D = 360°

∠D = 360° - 820°

∠D = -460°

Since angle D is not possible to be negative, we know that there must be a mistake in the diagram. We need to make sure that the figure is correct before we can find the value of y.

After dilating Triangle ABC with a scale factor of 1/4, the new coordinates of A', B', and C' are A'(2,1), B'(3,1), and C'(4,3), respectively.

To dilate Triangle ABC with a scale factor of 1/4, we need to multiply the coordinates of each vertex by the scale factor.

Let's apply the scale factor to each coordinate:

A' = (8 * 1/4, 4 * 1/4)

  = (2, 1)

B' = (12 * 1/4, 4 * 1/4)

  = (3, 1)

C' = (16 * 1/4, 12 * 1/4)

The expected payout is 5.625 cents, and the cost to play the game is 7 cents, it can be concluded that paying 7 cents to play this game is not fair. The expected payout is lower than the cost, resulting in a disadvantage for the player.

In this game, tossing 3 fair coins results in different payouts for the number of heads obtained. The payouts are 12 cents for 3 heads, 7 cents for 2 heads, and 4 cents for 1 head. The question is whether paying 7 cents to play this game is fair.

To determine if the game is fair, we need to compare the expected payout with the cost to play. Let's calculate the probabilities and payouts for each outcome. There are a total of 8 possible outcomes when tossing 3 coins: HHH, HHT, HTH, THH, TTH, THT, HTT, and TTT (H denotes a head, and T denotes a tail).

The probability of getting 3 heads is 1/8, so the payout for this outcome is 12 cents. The probability of getting 2 heads is 3/8 (HHH, HHT, HTH), so the payout for this outcome is 7 cents. The probability of getting 1 head is also 3/8 (TTH, THT, HTT), resulting in a payout of 4 cents. The probability of getting 0 heads (3 tails) is 1/8, resulting in a payout of 0 cents.

Now, let's calculate the expected payout by multiplying each outcome's probability with its corresponding payout and summing them up:

Expected payout = (1/8 * 12) + (3/8 * 7) + (3/8 * 4) + (1/8 * 0) = 1.5 + 2.625 + 1.5 + 0 = 5.625 cents.

Since the expected payout is 5.625 cents, and the cost to play the game is 7 cents, it can be concluded that paying 7 cents to play this game is not fair. The expected payout is lower than the cost, resulting in a disadvantage for the player.

When talking about a limit of a function at a particular point, it's significant to note that this means evaluating the function as the input approaches that point. It's worth noting that the point in question must be a limit point of the domain of the function for the function to have a limit.

An isolated point is one that doesn't have any other points near it in the domain of the function. Because of this, it makes no sense to consider the limit of a function at an isolated point of the domain of the function.

A limit is defined as the value that a function approaches as the input (x) approaches a certain point (c). This definition is simple enough, but it necessitates the function having values near that point in the domain. That is to say, there must be a sufficient number of points near the point c in the domain such that we can talk about the input approaching c without going out of the domain.

The Fahrenheit temperature of the cup of water after 5 minutes is approximately 194°F.

According to Newton's Law of Cooling, the temperature of an object decreases proportionally to the difference between its temperature and the surrounding temperature. The formula is given as:

T = T_a + (T_0 - T_a) * e^(-kt)

In this case, T_a represents the temperature of the room (67°F), T_0 represents the initial temperature of the water (201°F), t represents time in minutes, T represents the temperature of the water at a given time, and k is the decay constant we need to find.

We know that after 3 minutes, the temperature of the water reaches 190°F. Plugging in these values into the equation:

190 = 67 + (201 - 67) * e^(-3k)

Simplifying the equation:

123 = 134 * e^(-3k)

Dividing both sides by 134:

e^(-3k) = 123/134

Taking the natural logarithm of both sides:

-3k = ln(123/134)

Dividing both sides by -3:

k ≈ ln(123/134) / -3 ≈ -0.0104

Now that we have the value of k, we can use the equation to determine the temperature of the water after 5 minutes:

T = 67 + (201 - 67) * e^(-0.0104 * 5)

Calculating the expression:

T ≈ 67 + 134 * e^(-0.052)

T ≈ 67 + 134 * 0.9492

T ≈ 67 + 127.2268

T ≈ 194.23°F

To find the exact value of tangent (19π/12), we can use the trigonometric identity:

tangent (θ) = sin (θ) / cos (θ).

First, let's find the values of sin (19π/12) and cos (19π/12).

Using the unit circle, we can determine that sin (19π/12) = -1/2 and cos (19π/12) = -√3/2.

Now we can substitute these values into the tangent formula:

tangent (19π/12) = sin (19π/12) / cos (19π/12) = (-1/2) / (-√3/2).

Simplifying the expression by multiplying the numerator and denominator by 2/√3:

tangent (19π/12) = (-1/2) * (2/√3) / (-√3/2) = (1/√3).

To rationalize the denominator, we multiply the numerator and denominator by √3:
