The coordinate of point R after the rotation is determined as = ( - 4, 7).

option A.

What is the rotation of a figure?

A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction.

You can turn a figure 90°, a quarter turn, either clockwise or counterclockwise. When you spin the figure exactly halfway, you have rotated it 180°. Turning it all the way around rotates the figure 360°.

When a figure is rotated 180 degrees, each point of the figure is moved to a new position that is exactly opposite its original position with respect to a fixed center of rotation.

The initial coordinate of point R = ( 4, 7),

The new coordinate of point R after the rotation = ( - 4, 7)

Answers

The likelihood that a customer who purchased more items than planned did not use a shopping list is approximately 0.51.

To determine the likelihood that a customer who purchased more items than planned did not use a shopping list, we need to calculate the conditional probability.

Let's focus on the "Bought more items than expected" column. The probability that a customer did not use a shopping list is given by the ratio of the "Did not have a shopping list" value in that column to the total value in that column.

The probability that a customer did not use a shopping list given that they bought more items than expected is:

0.18 / 0.35 ≈ 0.51 (rounded to two decimal places)

Consequently, the probability that a consumer who spent more money than anticipated did not make a shopping list is roughly 0.51.

Find an equation of a line in a point-slope form passing through the points (2,4) and (3,6) . Then write the answer in a slope-intercept form. Then write the answer in standard form. Graph the line on cartesian plane and upload the image. Show your work (the steps)!

Answers

The equation of the line in point-slope form, slope-intercept form and standard form is y - 4 = 2( x - 2 ), y = 2x and 2x - y = 0 respectively.

What is the equation of line passing through the points (2,4) and (3,6)?

The slope-intercept form is expressed as;

y = mx + b

Where m is slope and b is the y-intercept.

Given that the line passes through points (2,4) and (3,6).

First, we determine the slope:

[tex]Slope\ m = \frac{y_2 - y_1}{x_2 - x_1} \\\\Slope\ m = \frac{6 - 4}{3-2} \\\\Slope\ m = \frac{2}{1} \\\\Slope\ m = 2[/tex]

Now, plug the slope m = 2 and point (2,4) into the point-slope form:

( y - y₁ ) = m( x - x₁ )

y - 4 = 2( x - 2 )

Solve in slope-intercept form:

y - 4 = 2( x - 2 )

y - 4 = 2x - 4

y = 2x - 4 + 4

y = 2x

Solve in standard form:

Ax + Bx = C

y - y  = 2x - y

0 = 2x - y

Reorder:

2x - y = 0

Therefore, the standard form is  2x - y = 0.

(ii) 9.375 months

What is a quadratic function?

A quadratic function is a function that can be expressed in the form; f(x) = a·x² + b·x + c, where a ≠ 0, and a, b, and c are numbers.

The model of the value of the investment in the bank obtained from the amount of his retirement funds David invested in the bank can be presented as follows;

a = 45 + 75·t - 4·t²

Where;

a = The value of the investment in thousand of dollars after t months

t = The number of months of the investment

(i) The initial amount David invested can be found by plugging in t = 0, in the function for the amount David invested in the bank, as follows;

a = 45 + 75 × 0 - 4 × 0² = 45

The initial amount David invested is; a = $45,000

(ii) The number of months it takes for David investment to reach a maximum value can be found from the quadratic function as follows;

The number of months t(max) at the maximum amount is; t(max) = -75/(2 × (-4)) = 9.375

Therefore, it will take 9.375 months for David's investment to reach a maximum value

The five-number summary for the height of 18 sunflowers include:

Minimum (Min) = 40.First quartile (Q₁) = 50.Median (Med) = 55.Third quartile (Q₃) = 55.75.Maximum (Max) = 63.

How to determine the five-number summary for the data?

In order to determine the five-number summary for the height of 18 sunflowers, we would arrange the data set in an ascending order:

40, 45, 47, 50, 50, 51, 51, 51, 55, 55, 55, 55, 55, 55, 58, 58, 62, 63

From the data set above, we can logically deduce that the minimum (Min) is equal to 40.

For the first quartile (Q₁), we have:

Q₁ = [(n + 1)/4]th term

Q₁ = (18 + 1)/4

Q₁ = 4.75th term

Q₁ = 4th term + 0.75(5th term - 4th term)

Q₁ = 50 + 0.75(50 - 50)

Q₁ = 50 + 0.75(0)

Q₁ = 50.

From the data set above, we can logically deduce that the median (Med) is given by:

Median = (9th term + 10th term)/2

Median = (55 + 55)/2

Median = 55

For the third quartile (Q₃), we have:

Q₃ = [3(n + 1)/4]th term

Q₃ = 3 × 4.75

Q₃ = 14.25th term

Q₃ = 14th term + 0.25(15th term - 14th term)

Q₃ = 55 + 0.25(58 - 55)

Q₃ = 55 + 0.25(3)

Q₃ = 55.75

In conclusion, the maximum height is equal to 63.

Question 4 A ladder 12 m long leans against a vertical wall with its foot 4.5 m away from the base of the wall as shown. What height does the ladder reach up the wall? (Leave your answer in 2 decimal places).​

Answers

To find the height that the ladder reaches up the wall, we can use the Pythagorean theorem.

which relates the lengths of the sides of a right triangle. In this case, the ladder forms the hypotenuse, the distance from the base of the wall to the foot of the ladder is one side (4.5 m), and the height we want to find is the other side.

In this case, the ladder forms the hypotenuse, and the distance from the foot of the ladder to the base of the wall is one of the sides.

Let's denote the height of the ladder on the wall as 'h'. According to the problem, the length of the ladder is 12 m, and the distance from the foot of the ladder to the base of the wall is 4.5 m.

Using the Pythagorean theorem, we have:

a^2 + b^2 = c^2

where a represents the height, b represents the distance from the base of the wall, and c represents the length of the ladder.

Substituting the given values, we have:

a^2 + (4.5)^2 = (12)^2

Simplifying:

a^2 + 20.25 = 144

a^2 = 144 - 20.25

a^2 = 123.75

Taking the square root of both sides:

a ≈ 11.11

Therefore, the ladder reaches a height of approximately 11.11 meters up the wall.

The front desk realizes they miss-charged the men, so the bell boy takes a $20 bill change to
the room. The men realize that you can’t split the $20 bill evenly 3 ways so they add it onto
the tip. The bell boy is happy but then thinks to himself: ”If the room is $270 and they had
this extra $20 that’s only $290, where did the other $10 go?”
Explain what is wrong with the Bell Boy’s thoughts, and what is the correct math here.

Answers

Answer:

Step-by-step explanation:

The bell boy added $270 and $20 incorrectly. The $20 bill was something that was returned due to overcharching. On the other hand, $270 was the amount that they paid for their room. This only means that $20 should be deducted from $270 and that's the amount that they paid for their room while $30 and $20 are the amount that the bell boy received as a tip

Total money of the three men: 3($100) = $300

They paid $270 for the room: $300 - $270 = $30

Tip for the bell boy: $30 - $30 = $0

Amount overcharged to them: $0 + $20 = $20

Tip to the bell boy: $20 - $20 = $0

They were left with no more money from the original $300.

How many minutes would you have to exercise each day to have a resting heart rate of 60 beats per minute? Equation

Answers

To determine the number of minutes you would have to exercise each day to have a resting heart rate of 60 beats per minute, we need to consider the relationship between exercise and heart rate.

Regular exercise can help lower resting heart rate as it strengthens the cardiovascular system. The American Heart Association recommends engaging in moderate-intensity aerobic exercise for at least 150 minutes per week to maintain cardiovascular health.

If we assume that you exercise evenly throughout the week, we can calculate the daily exercise time as follows:

150 minutes per week ÷ 7 days = approximately 21.43 minutes per day.

Therefore, if you exercise for approximately 21.43 minutes per day, it can contribute to maintaining a healthy resting heart rate. It's important to note that individual results may vary, and consulting with a healthcare professional is always recommended before starting or modifying an exercise routine.

However, it's crucial to understand that exercise alone may not be the sole factor affecting resting heart rate. Other factors, such as genetics, overall health, stress levels, and lifestyle choices, can also influence heart rate. Additionally, achieving a resting heart rate of 60 beats per minute may not be feasible or suitable for everyone, as the ideal range can vary based on individual circumstances.

Therefore, while regular exercise can be beneficial for cardiovascular health, it's essential to consider personalized factors and consult with a healthcare professional for tailored advice on achieving and maintaining a healthy resting heart rate.

[tex]\sf A[/tex] = the future value of the investment

[tex]\sf P[/tex] = the initial principal (amount invested)

[tex]\sf r[/tex] = the interest rate (as a decimal)

[tex]\sf n[/tex] = the number of times interest is compounded per year

[tex]\sf t[/tex] = the number of years

A man walks up 800m road AB which slopes at 10.2 to the horizon. He then walks 300m down road BC, which is at 6.3 to the horizon. The horizon is parallel to AD and BF perpendicular to AD. Find the length of CD​

Answers

The length of CD is approximately 27.931 meters.

To find the length of CD, we can use the concept of similar triangles and trigonometric ratios.

Let's start by drawing a diagram to visualize the situation:

      A----------B

     /           /

    /           /

   /           /

  D----------C

  |

  |

  |

  F

We are given that road AB slopes at 10.2 degrees to the horizon and road BC slopes at 6.3 degrees to the horizon. From the diagram, we can see that angle DAF is the same as the slope angle of road AB (10.2 degrees), and angle DCF is the same as the slope angle of road BC (6.3 degrees).

Now, we can set up the following trigonometric equations using the given information:

tan(10.2 degrees) = CD / AD (equation 1)

tan(6.3 degrees) = CD / BF (equation 2)

Since AD and BF are perpendicular, we can consider them as vertical heights. Let's calculate the lengths of AD and BF.

For road AB, we can use the definition of tangent:

tan(10.2 degrees) = height AB / length AB

Solving for the height AB, we have:

height AB = tan(10.2 degrees) * length AB

height AB = tan(10.2 degrees) * 800m

height AB ≈ 147.294m

Similarly, for road BC:

height BC = tan(6.3 degrees) * length BC

height BC = tan(6.3 degrees) * 300m

height BC ≈ 33.706m

Now, we can substitute these values into equations 1 and 2:

tan(10.2 degrees) = CD / 147.294m (equation 1)

tan(6.3 degrees) = CD / 33.706m (equation 2)

Solving equation 1 for CD:

CD = tan(10.2 degrees) * 147.294m

CD ≈ 27.931m

Therefore, the length of CD is approximately 27.931 meters.

To find the value of 'x', we can use the property of parallel lines that states when a transversal intersects two parallel lines, the corresponding angles are equal.

In triangle ABC, we have DE parallel to BC. Therefore, we can conclude that triangle ADE is similar to triangle ABC.

Using the property of similar triangles, we can set up the following proportion:

[tex]\displaystyle\sf \dfrac{AD}{DB} = \dfrac{AE}{EC}[/tex]

Substituting the given values:

[tex]\displaystyle\sf \dfrac{6x - 7}{4x - 3} = \dfrac{3x - 3}{2x - 1}[/tex]

To solve this proportion for 'x', we can cross-multiply:

[tex]\displaystyle\sf (6x - 7)(2x - 1) = (4x - 3)(3x - 3)[/tex]

Expanding both sides:

[tex]\displaystyle\sf 12x^{2} - 6x - 14x + 7 = 12x^{2} - 9x - 12x + 9[/tex]

Combining like terms:

[tex]\displaystyle\sf 12x^{2} - 20x + 7 = 12x^{2} - 21x + 9[/tex]

Moving all terms to one side:

[tex]\displaystyle\sf 12x^{2} - 12x^{2} - 20x + 21x = 9 - 7[/tex]

if the standard deviation of 3,6,x,7,5 is square root 2 find the positive value of x​

Answers

Using the formula for the standard deviation and solving for x, we will get:

x = 7.6

How to find the value of x?

To find the positive value of 'x' in the given set of numbers (3, 6, x, 7, 5) when the standard deviation is √2, we can use the formula for standard deviation.

The formula for calculating the sample standard deviation is as follows:

σ = √[(Σ(xi - m)²) / (n - 1)]

Where:

σ is the standard deviationΣ is the summation symbolxi represents each value in the datasetm is the mean of the datasetn is the number of values in the dataset

First, let's calculate the mean (m) of the given set of numbers:

Mean (m) = (3 + 6 + x + 7 + 5) / 5 = (21 + x) / 5

Next, let's substitute the values into the standard deviation formula:

√2 = √[( (3 - (21 + x) / 5)² + (6 - (21 + x) / 5)² + (x - (21 + x) / 5)² + (7 - (21 + x) / 5)² + (5 - (21 + x) / 5)² ) / 4]

Simplifying the equation:

2 = [( (3 - (21 + x) / 5)² + (6 - (21 + x) / 5)² + (x - (21 + x) / 5)² + (7 - (21 + x) / 5)² + (5 - (21 + x) / 5)² ) / 4]

Multiplying both sides of the equation by 4:

8 = (3 - (21 + x) / 5)² + (6 - (21 + x) / 5)² + (x - (21 + x) / 5)² + (7 - (21 + x) / 5)² + (5 - (21 + x) / 5)²

Expanding and simplifying:

8 = (15 - (21 + x) / 5)² + (30 - (21 + x) / 5)² + (5x/5)² + (35 - (21 + x) / 5)² + (25 - (21 + x) / 5)²

8 = (15 - (21 + x) / 5)² + (30 - (21 + x) / 5)² + x² + (35 - (21 + x) / 5)² + (25 - (21 + x) / 5)²

Expanding and simplifying further:

8 = (225 - 2(21 + x) + (21 + x)² / 25) + (900 - 2(21 + x) + (21 + x)² / 25) + x² + (1225 - 2(21 + x) + (21 + x)² / 25) + (625 - 2(21 + x) + (21 + x)² / 25)

Combining like terms:

8 = (225 + 900 + 1225 + 625) / 25 - 10(21 + x) + 5(21 + x)² / 25 + x²

8 = 2975 / 25 - 10(21 + x) + 5(21 + x)² / 25 + x²

Simplifying:

8 = 119 - 10(21 + x) + (21 + x)² / 5 + x²

Rearranging the terms:

8 - 119 = -10(21 + x) + (21 + x)² / 5 + x²

-111 = -10(21 + x) + (21 + x)² / 5 + x²

Multiplying through by 5 to eliminate the fraction:

-555 = -50(21 + x) + (21 + x)² + 5x²

Expanding and simplifying:

-555 = -1050 - 50x + x² + 441 + 42x + x² + 5x²

Combining like terms:

0 = 7x² - 8x - 114

Now, we can solve this quadratic equation to find the value of 'x'.

Using the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

In this case, a = 7, b = -8, and c = -114.

Plugging the values into the formula:

x = (-(-8) ± √((-8)² - 4(7)(-114))) / (2(7))

Simplifying:

x = (8 ± √(64 + 3192)) / 14

x = (8 ± 2√(814)) / 14

x = (4 ± √(814)) / 7

Therefore, the values of 'x' that satisfy the given equation are approximately:

x ≈ (4 + √(814)) / 7 ≈ 7.62

x ≈ (4 - √(814)) / 7 ≈ -0.29

Since we are looking for the positive value of 'x', the solution is:

x ≈ 7.6

Two buildings are 18 m part. The shorter building is 12 m high while the taller one is 19 m high. Find the distance, x m between the top of the buildings. ​

Answers

The distance between the tops of the buildings is 28.5 meters.

To find the distance between the top of the buildings, we can use the concept of similar triangles.

Let's denote the height of the shorter building as "a" (12 m) and the height of the taller building as "b" (19 m). The distance between the buildings can be denoted as "c" (18 m), and the distance between the top of the buildings as "x" (which we need to find).

We can set up a proportion based on the similar triangles formed by the buildings:

a/c = b/x

Substituting the known values:

12/18 = 19/x

To find "x," we can cross-multiply and solve for "x":

12x = 18 * 19

12x = 342

x = 342/12

x = 28.5 m

Therefore, the distance between the tops of the buildings is 28.5 meters.

The population of a town increased from 3700 in 2005 to 5900 in 2009. Find the absolute and relative (percent) increase.

Absolute increase:


Relative increase:
%

Answers

The absolute increase in population is 2200, and the relative increase is approximately 59.46%.

To find the absolute and relative increase in population, we can use the following formulas:

Absolute increase = Final value - Initial value

Relative increase = (Absolute increase / Initial value) * 100%

Given the population in 2005 is 3700 and the population in 2009 is 5900, we can calculate the absolute and relative increase as follows:

Absolute increase = 5900 - 3700 = 2200

To calculate the relative increase, we need to divide the absolute increase by the initial value and then multiply by 100:

Relative increase = (2200 / 3700) * 100% ≈ 59.46%

Therefore, the absolute increase in population is 2200, and the relative increase is approximately 59.46%.

The absolute increase represents the actual difference in population count between the two years, while the relative increase gives us the percentage change relative to the initial value. In this case, the population increased by 2200 individuals, and the relative increase indicates that the population grew by approximately 59.46% over the given period.

Note that the relative increase is expressed as a percentage, which makes it easier to compare changes across different populations or time periods.

Using the Pythagorean Theorem, prove whether or not the following triangle is a right
triangle. Remember to show your work.
A triangle with side lengths of 13m, 5m and 10m
A) Is it a right triangle (1 point)
B) Explain and show your work (4 points)

Answers

A) The triangle is not a right triangle.

B) Based on the calculations, the square of the longest side is not equal to the sum of the squares of the other two sides, indicating that the triangle does not meet the criteria of a right triangle according to the Pythagorean Theorem.

To determine if the triangle with side lengths 13m, 5m, and 10m is a right triangle, we can apply the Pythagorean Theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Let's calculate the squares of the side lengths:

13^2 = 169

5^2 = 25

10^2 = 100

According to the Pythagorean Theorem, if this triangle is a right triangle, the square of the longest side (13^2 = 169) should be equal to the sum of the squares of the other two sides (5^2 + 10^2 = 25 + 100 = 125).

Since 169 is not equal to 125, we can conclude that the triangle with side lengths 13m, 5m, and 10m is not a right triangle. The sum of the squares of the shorter sides is less than the square of the longest side, which does not satisfy the condition for a right triangle.

George Kasey, the CEO of Kasey Food, a Canadian chain of meat production, raised concerns that business is slow due to the lack of focus on innovation.While Kasey Food had been very successful in marketing their products in the past, it is currently seeing a decline in sales. George K. had previously challenged his leadership team to come up with innovative ideas to drive continued success, but results have not yet improved. The chain suffers especially because of the unexpected rise in demand for vegan food. Therefore George K. started looking for a potential business partner to expedite the company's involvement in vegan products.In addition to the possibility of acquiring knowledge and skills around vegan nutrition, Kasey Food is evaluating a merger with an innovative company that is based in Southern America. This would also provide an opportunity to (at least partially) transfer production to save on costs and to secure access to the continent's market after Pandemic. Concerning this possible merger, the business development manager has already started looking into potential legal issues.As a next step, the business development manager worked on an analysis to identify where the company currently stands and what it wants to achieve in a new combined post- merger organization. Based on the findings, a decision was made to limit potential merger partners to companies that have similar target customers, i.e. a focus on retailers and restaurants, to build a sustainable combined business model.However, the company cultures of potential partners investigated could not be more different. Kasey Food's employees benefit from long-term employment, working in a highly process-driven and structured environment. In contrast, the staff of companies that are rising stars in the vegan food space are usually very young teams, living in a company culture that is driven by flat hierarchies, pragmatism, and fast pace.While George K. is close to deciding regarding the merger, managers are reporting that morale amongst workers is declining. Employees are sensing upcoming changes but have not been informed officially. Therefore, many rumors exist, and a general anxiety is building up.
