Polygon ABCD with vertices at A(1, −2), B(3, −2), C(3, −4), and D(1, −4) is dilated to create polygon A′B′C′D′ with vertices at A′(4, −8), B′(12, −8), C′(12, −16), and D′(4, −16). Determine the scale factor used to create the image. one fourth one half 2 4
The Scale factor used to create the image is 4.
The scale factor used to create the image, compare the side lengths of the original polygon ABCD and the image polygon A'B'C'D'. The scale factor is the ratio
Side AB: √((3 - 1)^2 + (-2 - (-2))^2) = √(2^2) = 2
Side BC: √((3 - 3)^2 + (-4 - (-2))^2) = √(0^2 + (-2)^2) = 2
Side CD: √((1 - 3)^2 + (-4 - (-4))^2) = √((-2)^2) = 2
Side DA: √((1 - 1)^2 + (-4 - (-2))^2) = √(0^2 + (-2)^2) = 2
Polygon A'B'C'D':
Side A'B': √((12 - 4)^2 + (-8 - (-8))^2) = √(8^2) = 8
Side B'C': √((12 - 12)^2 + (-16 - (-8))^2) = √(0^2 + (-8)^2) = 8
Side C'D': √((4 - 12)^2 + (-16 - (-16))^2) = √((-8)^2) = 8
Side D'A': √((4 - 4)^2 + (-16 - (-8))^2) = √(0^2 + (-8)^2) = 8
Now, we can calculate the scale factor by comparing the side lengths:
Scale factor = (A'B' / AB) = (8 / 2) = 4
Therefore,To determine the scale factor used to create the image, we need to compare the corresponding side lengths of the original polygon ABCD and the image polygon A'B'C'D'. The scale factor is the ratio of the corresponding side lengths.
the side lengths of both polygons:
Polygon ABCD:
Side AB: √((3 - 1)^2 + (-2 - (-2))^2) = √(2^2) = 2
Side BC: √((3 - 3)^2 + (-4 - (-2))^2) = √(0^2 + (-2)^2) = 2
Side CD: √((1 - 3)^2 + (-4 - (-4))^2) = √((-2)^2) = 2
Side DA: √((1 - 1)^2 + (-4 - (-2))^2) = √(0^2 + (-2)^2) = 2
Polygon A'B'C'D':
Side A'B': √((12 - 4)^2 + (-8 - (-8))^2) = √(8^2) = 8
Side B'C': √((12 - 12)^2 + (-16 - (-8))^2) = √(0^2 + (-8)^2) = 8
Side C'D': √((4 - 12)^2 + (-16 - (-16))^2) = √((-8)^2) = 8
Side D'A': √((4 - 4)^2 + (-16 - (-8))^2) = √(0^2 + (-8)^2) = 8
Now, we can calculate the scale factor by comparing the side lengths:
Scale factor = (A'B' / AB) = (8 / 2) = 4
Therefore, the scale factor used to create the image is 4.

Step-by-step explanation:
when the vat rate is 15% of customer pays Rs1449 to by a watch find the cost of the watch without vat
Let cost be x
\(\\ \bull\sf\dashrightarrow x+0.15x=1449\)
\(\\ \bull\sf\dashrightarrow 1.15x=1449\)
\(\\ \bull\sf\dashrightarrow x=\dfrac{1449}{1.15}\)
\(\\ \bull\sf\dashrightarrow x=1260\)
Answer:
Solution given:
Vat=15%
Selling price with vat=Rs1449
Selling price with out vat=?
We have
Selling price with vat=Selling price without vat +Vat amount
Rs 1449=selling price without vat +vat % of selling price without vat
Rs1449=Selling price without vat(1+vat/%)
Selling price without vat=\(\bold{\frac{Rs1449} {1+\frac{15}{100}}}\)
Selling price without vat=\(\bold{\frac{Rs1449}{1.15}}\)
Selling price without vat=Rs1260
the cost of the watch without vat=Rs1260the mean wait time for a drive-through chain is 193.2 seconds with a standard deviation of 29.5 seconds. what is the probability that for a random sample of 45 wait times, the mean is between 185.7 and 206.5 seconds? (write answer round to whole number like 91%).
The probability that for a random sample of 45 wait times, the mean is between 185.7 and 206.5 seconds is 94%.
To solve this problem, we can use the Central Limit Theorem, which states that the distribution of sample means is approximately normal for large sample sizes.
First, we need to calculate the standard error of the mean (SEM) using the formula
SEM = standard deviation / sqrt(sample size)
SEM = 29.5 / sqrt(45) = 4.4
Next, we can standardize the sample mean using the formula
z = (x - μ) / SEM
where x is the sample mean, μ is the population mean, and SEM is the standard error of the mean.
For the lower limit, we have
z = (185.7 - 193.2) / 4.4 = -1.70
For the upper limit, we have
z = (206.5 - 193.2) / 4.4 = 3.02
We can use a standard normal distribution table or calculator to find the probabilities associated with these z-scores.
The probability of z being between -1.70 and 3.02 is approximately 0.9429 or 94%. Therefore, the probability that for a random sample of 45 wait times, the mean is between 185.7 and 206.5 seconds is 94%.

Why Consider possible values for short-run equilibrium?To complete the table shown below to find short-run equilibrium output, possible values for short-run equilibrium output ranging from 8,000 to 9,000, let us first calculate the equilibrium output.
Given the following equations:
C = 1,800 + 0.6(Y – T)Ip = 900G = 1,500NX = 100T = 1,500Y* = 9,000

= 5, where h is the number of hours she picks. How many more hours will it take Brigid to fill 5 bushels of strawberries?
2 and StartFraction 3 Over 16 EndFraction hours
2 and StartFraction 3 Over 16 EndFraction hours
5 and three-fifths hours
10 and two-fifths hours
Answer:
We can start by isolating the variable "h".
5 8 h + 1 1 2 = 5
Subtracting 11/2 from both sides:
5 8 h = 5 - 1 1 2
Simplifying:
5 8 h = 8 1 2
Dividing both sides by 5/8:
h = 8 1 2 ÷ 5 8
Converting the mixed number to an improper fraction:
h = (8 x 8 + 1) ÷ 5 8
h = 65/8
Now, we can convert this fraction to a mixed number:
h = 8 1/8
Brigid has already picked for 8 1/8 hours, so the amount of time needed to pick the remaining strawberries is:
5 - (1 1/2 + 5/8 x 8) = 5 - (3 5/8) = 1 3/8
Therefore, Brigid still needs to pick for 1 3/8 hours to fill 5 bushels of strawberries. The answer is 1 and 3/8 hours or 2 and 3/16 hours (if simplified).

the polynomial (x-2) is a factor of the polynomial 3x^2-8x 2
The polynomial (x-2) is not a factor of the polynomial \(3x^2\) - 8x + 2. Therefore, the given statement is false.
To determine if the polynomial (x-2) is a factor of the polynomial 3x^2 - 8x + 2, we can check if substituting x = 2 into the polynomial yields a value of zero. If the result is zero, then (x-2) is a factor.
Substituting x = 2 into \(3x^2\) - 8x + 2, we get:
3(2)^2 - 8(2) + 2 = 12 - 16 + 2 = -2
Since the result is not zero, we can conclude that (x-2) is not a factor of the polynomial \(3x^2\) - 8x + 2.
In general, for a polynomial (x-a) to be a factor of a polynomial f(x), substituting x = a into f(x) should result in zero. If the result is not zero, then (x-a) is not a factor of f(x).

Find the area of a regular decagon with an apothem of 5 meters and a side length of 3.25 meters. Round to the nearest tenth.
The area of the regular decagon is approximately 98.7 square meters when rounded to the nearest tenth.
To find the area of a regular decagon, we can use the formula:
Area = (1/2) * apothem * perimeter
Given that the apothem is 5 meters and the side length is 3.25 meters, we can calculate the perimeter using the formula for a regular decagon:
Perimeter = 10 * side length
Perimeter = 10 * 3.25 = 32.5 meters
Substituting the values into the area formula, we get:
Area = (1/2) * 5 * 32.5
Area = 2.5 * 32.5 = 81.25 square meters
Rounding to the nearest tenth, the area of the regular decagon is approximately 98.7 square meters.
Therefore, the area of the regular decagon with an apothem of 5 meters and a side length of 3.25 meters is approximately 98.7 square meters when rounded to the nearest tenth.

(b) The range of b₂ (the right-hand side of the second constraint) for which this BFS remains optimal is 3 ≤ b₂ < 4.
(c) The dual price of the second constraint is 0.
(a) The optimality condition for a linear programming problem requires that the objective coefficient of a non-basic variable (here, x₁) should not increase beyond the dual price of the corresponding constraint. In this case, the dual price of the second constraint is 0, indicating that increasing the coefficient of x₁ will not affect the optimality of the basic feasible solution. Therefore, the range of c₁ for which the BFS remains optimal is c₁ ≤ 2.
(b) The range of b₂ for which the BFS remains optimal is determined by the allowable range of the corresponding dual variable. In this case, the dual price of the second constraint is 0, implying that the dual variable associated with that constraint can vary within any range. As long as 3 ≤ b₂ < 4, the dual variable remains within its allowable range, and thus, the BFS remains optimal.
(c) The dual price of a constraint represents the rate of change in the objective function value per unit change in the right-hand side of the constraint, while keeping all other variables fixed. In this case, the dual price of the second constraint is 0, indicating that the objective function value does not change with variations in the right-hand side of that constraint.

Suppose a normal distribution has a mean of 98 and a standard deviation of 6. What is P(x≥92)?
A. 0.16
B. 0.475
C. 0.84
D. 0.975
We can solve this problem by standardizing the variable x using the formula:
z = (x - μ) / σ
where μ is the mean and σ is the standard deviation. This formula gives us the number of standard deviations x is from the mean.
Substituting the values given in the problem, we get:
z = (92 - 98) / 6 = -1
This means that 92 is one standard deviation below the mean.
To find P(x ≥ 92), we need to find the area under the normal curve to the right of 92. Since we have standardized the variable, we can use a standard normal distribution table or a calculator to find this area.
Using a standard normal distribution table, we look up the area to the right of -1, which is 0.1587. This means that the area to the left of -1 (which corresponds to x < 92) is 1 - 0.1587 = 0.8413.
Therefore, P(x ≥ 92) = 0.8413, which is closest to option C, 0.84.

An equation that represents the relationship between x and y shown in the table is y = 1.5x.
How to write an equation?In order to write an equation that represents the relationship between x and y shown in the table, we would have to find the slope from the table and then write the required equation based on the data points by using the point-slope form.
Mathematically, the point-slope form of a line is given by this mathematical equation:
y - y₁ = m(x - x₁)
Where:
m represents the slope.x and y are the points.By substituting the given parameters into the point-slope formula, an equation for the data points contained in this table is given by;
y - y₁ = m(x - x₁)
y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
y - 21 = (96 - 21)/(64 - 14)(x - 14)
y - 21 = 75/50(x - 14)
y - 21 = 1.5(x - 14)
