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)

  = (4, 3)

Therefore, after dilating Triangle ABC with a scale factor of 1/4, the new coordinates of A', B', and C' are (2,1), (3,1), and (4,3) respectively. The scale factor of 1/4 shrinks the original triangle by a factor of 1/4 in both the x and y directions, resulting in a smaller triangle with the new coordinates.

The cost of one cherry pie is $7 and the cost of one pumpkin pie is $13. To find the cost of each cherry pie and each pumpkin pie, we can set up a system of equations based on the given information. Let's represent the cost of a cherry pie as 'c' and the cost of a pumpkin pie as 'p'.

From Lelia's sales, we can write the equation: 12c + 11p = 227.

From Saige's sales, we can write the equation: 2c + 3p = 53.

To solve this system of equations, we can use various methods such as substitution or elimination. Let's use the elimination method in this case.

Multiplying the second equation by 6 to make the coefficients of 'c' the same in both equations, we get:

12c + 18p = 318.

Now, subtracting the first equation from this new equation, we have:

(12c + 18p) - (12c + 11p) = 318 - 227,

7p = 91.

Dividing both sides by 7, we find p = 13.

Substituting this value of p back into either of the original equations, we can solve for c. Let's use the first equation:

12c + 11(13) = 227,

12c + 143 = 227,

12c = 227 - 143,

12c = 84,

c = 7.

Therefore, the cost of one cherry pie is $7 and the cost of one pumpkin pie is $13.

The function being integrated and considering convergence at individual points and behavior at infinity, one can determine whether an integral converges or diverges.

To determine if an integral converges or diverges, one must analyze the behavior of the function being integrated and evaluate certain criteria.

When dealing with improper integrals (integrals with infinite limits or integrals of unbounded functions), there are two key criteria to consider: convergence at a single point and behavior at infinity.

Convergence at a single point: If the function being integrated has a finite value at a particular point within the integration limits, then the integral converges at that point. However, if the function approaches infinity or oscillates without settling on a specific value at that point, the integral diverges.

Behavior at infinity: For integrals with infinite limits, it is crucial to determine the behavior of the function as the variable approaches infinity. If the function approaches zero or a finite value as the variable grows indefinitely, the integral converges. However, if the function approaches infinity or oscillates without settling on a specific value, the integral diverges.

To apply these criteria effectively, it may be necessary to use additional techniques such as comparison tests (e.g., the limit comparison test, integral comparison test), the ratio test, the root test, or other methods tailored to specific functions or situations. These techniques allow for a more rigorous analysis of convergence or divergence.

The box slides along the rough surface for a distance of d meters. At the bottom of the ramp, the box has zero potential energy and maximum kinetic energy.

To determine the distance the box slides along the rough surface, we need to consider the conservation of energy and the effects of friction.

Initially, the box is at a height of 0.25 m and has potential energy given by mgyo, where m is the mass of the box (2.0 kg) and yo is the initial height (0.25 m). As the box slides down the frictionless ramp, the potential energy is converted into kinetic energy. At the bottom of the ramp, the box has zero potential energy and maximum kinetic energy.

Upon reaching the rough horizontal surface, the box encounters friction. The work done by friction results in the conversion of kinetic energy into thermal energy, reducing the box's speed.

To calculate the distance the box slides on the rough surface, we need to determine the work done by friction. The work done by friction is given by the equation work = force × distance. The force of friction can be calculated using the equation force = friction coefficient × normal force, where the normal force is equal to the weight of the box (mg).

Using the given friction coefficient (μ = 0.50) and the mass of the box (m = 2.0 kg), we can calculate the force of friction. Once we have the force of friction, we can calculate the work done by friction.

The work done by friction is equal to the change in kinetic energy of the box. We can equate this work to the initial kinetic energy and solve for the distance traveled (d). The initial kinetic energy is given by (1/2)mv², where v is the velocity of the box at the bottom of the ramp.

By solving the equation for the work done by friction and equating it to the initial kinetic energy, we can determine the distance the box slides along the rough surface (d).

Let's break down the equation step by step. The total amount Patty paid for the 12 vests after the discount was $132. This means that the reduced price of each vest is $132 divided by 12, which is $11.

Now, let's consider the original price Festive Features charges for a vest, denoted as "v." Since the price was reduced by $6 for the bulk order, the reduced price is v - $6. According to the information given, the reduced price of each vest is $11.

Therefore, we can set up the equation: 12(v - 6) = 132. Here, 12 represents the number of vests Patty ordered, and (v - 6) represents the reduced price of each vest. By multiplying the reduced price by the quantity, we should get the total amount Patty paid, which is $132.

Simplifying the equation: 12v - 72 = 132. Adding 72 to both sides of the equation gives us 12v = 204. Finally, dividing both sides by 12, we find that v = 17. Hence, Festive Features normally charges $17 for a vest before the bulk order discount.

The length of the scale model of the football field is 15 inches.

The length of the scale model of the football field is 4.5 inches. The scale of 3 inches: 20 yards means that for every 3 inches on the model, it represents 20 yards in real life.

To find the length of the model, we can set up a proportion. Let x represent the length of the model in inches. Then, we have the proportion:

3 inches / 20 yards = x inches / 100 yards

Cross-multiplying gives us:

20 yards * x inches = 3 inches * 100 yards

Simplifying further:

20x = 300

Dividing both sides by 20:

x = 15

Therefore, the length of the model of the field is 15 inches.

The line of best fit equation in slope-intercept form is y = -4x + 120.

The line of best fit is used in mathematics, it is also known as a trend line or regression line. It is a straight line that is most likely to represent the given data and is used to summarize or describe a relationship between two variables.In order to get the equation of the line of best fit in slope-intercept form from the given data, we need to calculate the slope and the y-intercept.Using the given data, we can plot a scatter plot as shown below: scatter plot.

Therefore, we can see that there is a negative correlation between the variables. This means that as one variable increases, the other variable decreases.

Thus, the slope of the line of best fit can be calculated as:

Slope = rise/run = Δy/Δx

where Δy is the change in y (vertical change) and Δx is the change in x (horizontal change).

Let's choose two points on the line of best fit: (0,120) and (30,0).

Then, we can calculate the slope as:

Slope = Δy/Δx = (0 - 120)/(30 - 0) = -4

Therefore, the slope of the line of best fit is -4.

Now, let's find the y-intercept by using one point on the line of best fit: (0,120).

Then, we can use the point-slope form of a line:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is a point on the line of best fit.

Substituting

m = -4, x1 = 0, and y1 = 120

y - 120 = -4(x - 0)y - 120 = -4xy = -4x + 120

Thus, the equation of the line of best fit in slope-intercept form is: y = -4x + 120.

The function between the given functions f(x) = x² + 5x and

g(x) = 8x² - 1 can be found by adding the two functions together.

The function between f(x) and g(x) is,

f(x) + g(x) = x² + 5x + 8x² - 1

= 8x² + x² + 5x - 1

= 9x² + 5x - 1

Given,

f(x) = x² + 5x

and

g(x) = 8x² - 1

We need to find the function between the given functions.

Since f(x) and g(x) are polynomials, we can find their greatest common factor.

f(x) can be written as x(x + 5), and g(x) can be written as (2x)²- 1.

The greatest common factor of the two polynomials is,

x(x + 5) + (2x - 1)(2x + 1)

= x² + 5x + 4x - 1

= x² + 9x - 1

Therefore, the function between f(x) and g(x) is,

f(x) + g(x) = x² + 5x + 8x² - 1

= 8x² + x² + 5x - 1

= 9x² + 5x - 1

In conclusion, the function between the given functions f(x) = x² + 5x

and g(x) = 8x² - 1 is represented by the equation
