The formula for a directed line segment is A = (x2 - x1, y2 - y1). It is a vector equation, meaning that it describes the direction and magnitude of a line segment, rather than its endpoint coordinates.  

A directed line segment is a line segment with a starting point and an ending point, where the direction of the line can be described in terms of its magnitude and direction. To calculate the directed line segment, first calculate the difference between the x-coordinates of the start and end points, and then calculate the difference between the y-coordinates of the start and end points. The result is the vector A, which describes the magnitude and direction of the line segment.

For example, consider a line segment with start point (1, 2) and end point (4, 6). To calculate the directed line segment, first calculate the difference between the x-coordinates of the start and end points (4 - 1 = 3). Then, calculate the difference between the y-coordinates of the start and end points (6 - 2 = 4). The result is the vector A = (3, 4). This vector describes the magnitude and direction of the line segment, with the magnitude being the length of the line segment, and the direction being the direction from the start point to the end point.

Jara has 2 alternatives: -2 and -1 A number line is a diagram that depicts numbers,

As we walk along the line from left to right, the numbers rise. Positive numbers are often to the right and negative numbers to the left of zero, which is typically in the middle of the line.

Jara wants to choose a negative number that, in this instance, is closer to zero than -3. This suggests that instead of choosing -3, she should choose a negative integer that is situated nearer to zero on the number line.

Step-by-step explanation:

The expression to represent how much more Elena spent is 4.1 + p.

Two friends shop for fresh fruit. Elena buys a watermelon for ​$8.55 and 5 pounds of cherries. Taniya buys a pineapple for ​$4.45 and 4 pounds of cherries.

Therefore, the expression to represent how much more Elena spent can be represented as follows:

hence,

p = price in​ dollars, per pound of cherries.

Hence,

amount Elena spent more = 8.55 + 5p - (4.45 + 4p)

amount Elena spent more = 8.55 + 5p - 4.45 - 4p

amount Elena spent more = 8.55 - 4.45 + 5p - 4p

Therefore,

amount Elena spent more = 4.1 + p

Step-by-step explanation:

Step-by-step explanation:

By using differentials, we can estimate the maximum error in the calculated area of a rectangle with measurements of 20 cm for length and 50 cm for width, each with a maximum measurement error of 0.1 cm.

The area of a rectangle is given by the formula A = length × width. In this case, the length is 20 cm and the width is 50 cm. To estimate the maximum error in the calculated area, we need to consider the effect of the maximum measurement error in both the length and the width.

Let's first calculate the differential of the area with respect to the length and width. The differential of the area dA is given by dA = (d(length) × width) + (length × d(width)). Here, d(length) and d(width) represent the maximum measurement errors in length and width, respectively. Since each measurement error is at most 0.1 cm, we can substitute d(length) = 0.1 cm and d(width) = 0.1 cm into the equation.

Now, let's plug in the values: dA = (0.1 cm × 50 cm) + (20 cm × 0.1 cm). Simplifying this equation, we get dA = 5 cm² + 2 cm² = 7 cm².

Therefore, the estimated maximum error in the calculated area of the rectangle is 7 cm². This means that the actual area of the rectangle could be up to 7 cm² higher or lower than the calculated value due to the measurement errors in length and width.

Hey there!

From the given figure;

An exterior angle is 127°.

To find: value of"X"

Now;

x+127° = 180°. [Being linear pair]

or, X = 180° - 127°

or, X = 53°

Therefore, the value of "X" is 53°.

Hope it helps!

Answer:

53°

Step-by-step explanation:

the extended line(the base and the line that extends past the triangle) is 180°. With an extended line that is 180°, the inside angle must be 180° - the outside angle, and the outside angle must be 180° - the inside angle. if the angle on the outside is 127°, then the inside angle(x) should be 180° - 127° or 53°.

to verify: all the inside angles must equal to 180°

the angle on the top is 90°( when there is that square thing on an angle it means it is 90°) and the angle on the right is 53°, so the remaining angle is 180 - (90° + 53°) or 37°.

90° + 53° + 37° = 180 °

In the given expressions (f x g)(-4) is -8a³ - 8a² + 12a + 12.

The Retail Positioning Matrix is a tool used in retail marketing that helps to visualize and evaluate potential positioning strategies. It is composed of two main dimensions: price and quality.

While quality relates to the perceived value of a product or service in terms of its features, advantages, and performance, price is the amount of money consumers are prepared to pay for a good or service.

High price/high quality, high price/poor quality, low price/high quality, and low price/low quality are the four quadrants that the matrix divides price and quality into.

Retailers can choose which positioning approach will work best in a particular market by looking at each of these four quadrants, which each feature a different positioning strategy.

A 95% confidence interval for percent of american adults who believe in aliens:  (0.6578, 0.7822)

In this question we have been given that in a survey conducted on an srs of 200 american adults, 72% of them said they believed in aliens

We need to find the 95% confidence interval for percent of american adults who believe in aliens.

95% confidence interval = (p ± z√[p(1 - p)/n])

Here, n = 200

p = 72%

p = 0.72

And the z-score for 95% confidence interval is 1.960

The upper limit of interval would be,

(p + z√[p(1 - p)/n])

= 0.72 + 1.960 √[0.72(1 - 0.72)/200]

= 0.72 + 1.960 √[(0.72 * 0.28)/200]

= 0.72 + 1.960 √0.001008

= 0.72 + 0.0622

= 0.7822

The lower limit of interval would be,

(p - z√[p(1 - p)/n])

= 0.72 - 1.960 √[0.72(1 - 0.72)/200]

= 0.72 - 1.960 √[(0.72 * 0.28)/200]

= 0.72 - 1.960 √0.001008

= 0.72 - 0.0622

= 0.6578

Therefore, a 95% confidence interval = (0.6578, 0.7822)

Option third is correct enlarged by a factor of 4 because the distance between two dots is 1.

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

We have a star showing in the picture.

We are considering the small star as the original image.

And the big star is the pre-image.

As we know,

The scale factor =

(length of the big star in the x-direction from the origin)/(length of the small star in the x-direction from the origin)

The distance between two dots is 1.

Scale factor = 8/3

As the scale factor is greater than 1 it means the image will be enlarged.

Thus, option third is correct, enlarged by a factor of 4 because the distance between two dots is 1.

Answer:

see explanation

Step-by-step explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6 , then

sum = 180° × 4 = 720°

sum the 6 angles and equate to 720

6x + 5x + 26.5 + 7x - 8 + 4x + 21.5 + 5x + 19 + 10x + 13.5 = 720 , that is

37x + 72.5 = 720 ( subtract 72.5 from both sides )

37x = 647.5 ( divide both sides by 37 )

x = 17.5

then

∠ A = 6x = 6(17.5) = 105°

∠ B = 5x + 26.5 = 5(17.5) + 26.5 = 87.5 + 26.5 = 114°

∠ C = 7x - 8 = 7(17.5) - 8 = 122.5 - 8 = 114.5°

∠ D = 4x + 21.5 = 4(17.5) + 21.5 = 70 + 21.5 = 91.5°

∠ E = 5x + 19 = 5(17.5) + 19 = 87.5 + 19 = 106.5°

∠ F = 10x + 13.5 = 10(17.5) + 13.5 = 175 + 13.5 = 188.5°
