The plane and ship are 7.5 km apart.

Given that the displacement vector from plane to ship is

−3.078i−6.47j+2.20k km

(b) How far apart are the plane and ship

To determine the magnitude of the displacement vector, we will use the distance formula.

Let the components of the displacement vector be:

A = -3.078, B = -6.47, C = 2.20

∴ The magnitude of the displacement vector is

|d| = √(A² + B² + C²)|d|

= √((-3.078)² + (-6.47)² + (2.20)²)|d|

= √9.47 + 41.98 + 4.84|d|

= √56.29|d|

= 7.5 km.

Answer:

d = 13

Step-by-step explanation:

First, the distance formula is needed:

\(d = \sqrt{(x_{2} - x_{1} )^{2} +(y_{2} - y_{1 })^{2} }\)

Next we assign the points

(2,-4) is point 1, (7,8) is point 2

\(d = \sqrt{(7 - 2 )^{2} +(8 - (-4))^{2} } \\d = \sqrt{5^{2} +12^{2} } \\d = \sqrt{25 + 144}\\ d = \sqrt{169} \\d = 13\)

Given two points (2,-4) and (7,8)

To find - The distance between given points.

We know the formula that is used to find the distance is given as

\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

We let P = (2,-4)

and Q = (7,8)

\(x_1=2, y_1=-4\\x_2=7,y_2=8\)

on substituting we get

\(d=\sqrt{(7-2)^2+(8+4)^2}\\ d=\sqrt{(5)^2+(12)^2} \\d=\sqrt{25+144} \\d=\sqrt{169}\\ d=13\)

Hence we get the distance between (2,-4) and (7,8) is 13.

Final answer - The distance is 13.

Answer:

Option c : 32 degree.

Step-by-step explanation:

2x + 2x + 14 + 6x + 6 = 180 degrees

10x = 160

x = 16

2x = 16 *2 = 32 degrees

Answer:

Step-by-step explanation:

Angles in a triangle add up to 180°

You take 2x+2x+14+6x+6=180°

Collect like term and add 2x+2x+6x+14+4=180°

10x+20=180°

10x=180°-20

10x=160÷10

x=16

16*2=32

16*2+14=46

16*6+6=100

A) we would send Order A to Factory 3.

B) we would send both Order B and Order C to Factory 3.

B 7,000 Factory 3

C 30,000 Factory 3

Total number of units produced for the company today: 37,000

Average cost per unit for all production today: $9.00

To make decisions about which factory to send the orders to on Monday and Tuesday, we need to compare the costs per unit for each factory and consider the total number of units to be produced. Let's go through each day's scenario and make the production decisions.

a) Monday: Order A for 15,000 units

To decide which factory to send the order to, we compare the costs per unit for each factory. We select the factory with the lowest cost per unit to minimize the average cost per unit for the company.

Let's assume the costs per unit for each factory are as follows:

Factory 1: $10 per unit

Factory 2: $12 per unit

Factory 3: $9 per unit

To calculate the total cost for each factory, we multiply the cost per unit by the number of units:

Factory 1: $10 * 15,000 = $150,000

Factory 2: $12 * 15,000 = $180,000

Factory 3: $9 * 15,000 = $135,000

Based on the calculations, Factory 3 has the lowest total cost for producing 15,000 units, with a total cost of $135,000. Therefore, we would send Order A to Factory 3.

b) Tuesday: Order B for 7,000 units and Order C for 30,000 units

We have two options: sending each order to a separate factory or sending both orders to the same factory. We need to compare the average cost per unit for each option and select the one that results in the lowest average cost per unit.

Let's assume the costs per unit for each factory remain the same as in the previous example. We will calculate the average cost per unit for each option:

Option 1: Sending orders to separate factories

For Order B (7,000 units):

Average cost per unit = ($10 * 7,000) / 7,000 = $10

For Order C (30,000 units):

Average cost per unit = ($9 * 30,000) / 30,000 = $9

Total number of units produced for the company today = 7,000 + 30,000 = 37,000

Average cost per unit for all production today = ($10 * 7,000 + $9 * 30,000) / 37,000 = $9.43 (rounded to two decimal places)

Option 2: Sending both orders to the same factory (Factory 3)

For Orders B and C (37,000 units):

Average cost per unit = ($9 * 37,000) / 37,000 = $9

Comparing the two options, we see that both options have the same average cost per unit of $9. However, sending both orders to Factory 3 simplifies the production process by consolidating the orders in one factory. Therefore, we would send both Order B and Order C to Factory 3.

Production Report for Tuesday:

Order # of Units Factory

B   7,000      Factory 3

C  30,000    Factory 3

Total number of units produced for the company today: 37,000

Average cost per unit for all production today: $9.00

The most appropriate choice for trigonometry will be given by -

Angle between beam and road is 0.33°

What is Trigonometry?

Trigonometry shows the relationship between sides and angles of a right angled triangle.

There are six trigonometrical functions. They are \(sin\theta, cos\theta, tan\theta, cos\theta, sec\theta, cosec\theta\)

\(sin\theta = \frac{perpendicular}{hypotenuse}\\\\cos\theta = \frac{base}{hypotenuse}\\\\tan\theta = \frac{perpendicular}{base}\\\\cot\theta = \frac{base}{perpendicular}\\\\sec\theta = \frac{hypotenuse}{base}\\\\cosec\theta = \frac{hypotenuse}{perpendicular}\\\)

Trigonometry is a very important tool in mathematics.

Here,

The headlights of an automobile are set such that the beam drops 2.00 in. for each 28.0 ft in front of the car.

According to the figure attached here, 2.0 inch forms the height of the triangle and 28.0 ft forms the base of the triangle

Let the angle be \(\theta\). Now trigonometry is applied here

\(tan\theta = \frac{\frac{2}{12}}{28}\\tan\theta = \frac{1}{6 \times 28}\\tan\theta = \frac{1}{168}\\\theta = tan^{-1}\frac{1}{168}\\\theta = 0.33^{\circ}\)

Angle between beam and road is 0.33°

Answer:

fourth option

Step-by-step explanation:

Given f(x) then f(x + a) represents a horizontal translation of f(x)

• If a > 0 then a shift left of a units

• If a < 0 then a shift right of a units

Thus

f(x) = (x - 11)³ ← has been translated right by 11 units

Given f(x) then f(x) + c represents a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Thus

f(x) = (x - 11)³ + 4

represents a translation 11 units right and 4 units up

Answer:

Option c

Step-by-step explanation:

-7 + (19 + 5) = (-7 + 19) + 5

Less than half of the surveyed internet users have posted photos or videos online. To determine if less than half of internet users have posted photos or videos online based on the poll, we can follow these steps:

1. Calculate the proportion of users surveyed who have posted photos or videos online.
2. Compare the proportion to 0.5 (which represents half).

Step 1: Calculate the proportion
The poll surveyed 1,765 internet users, and 865 of them posted a photo or video online. To calculate the proportion, we can divide the number of users who posted (865) by the total number of users surveyed (1,765):

Proportion = 865 / 1,765 ≈ 0.49

Step 2: Compare the proportion to 0.5
Since 0.49 is less than 0.5, it appears that less than half of the surveyed internet users have posted photos or videos online.

However, we cannot conclude that this is true for all internet users, as the poll surveyed a limited sample size of 1,765 users. A larger, more representative sample may be needed to draw a more accurate conclusion.

According to the given statement comparing the two loans, we can see that the second loan(I2 = $9,324.00) with a higher principal but a lower interest rate has a slightly higher cost of credit.

To compare the cost of credit for the two loans, we can calculate the total interest paid for each loan.

For the first loan:

Principal (P1) = $12,000.00

Interest rate (r1) = 25.8% = 0.258

Time (t1) = 3 years

The total interest (I1) can be calculated using the formula:

I1 = P1 × r1 × t1

I1 = $12,000.00 × 0.258 × 3

I1 = $9,288.00

Therefore, the total interest paid for the first loan is $9,288.00.

For the second loan:

Principal (P2) = $24,000.00

Interest rate (r2) = 12.9% = 0.129

Time (t2) = 3 years

The total interest (I2) can be calculated using the same formula:

I2 = P2 × r2 × t2

I2 = $24,000.00 × 0.129 × 3

I2 = $9,324.00

Therefore, the total interest paid for the second loan is $9,324.00.

Comparing the two loans, we can see that the second loan with a higher principal but a lower interest rate has a slightly higher cost of credit. The $24,000.00 loan for 3 years at 12.9% interest has a cost of credit of $9,324.00, which is higher than the $9,288.00 cost of credit for the $12,000.00 loan for 3 years at 25.8% interest.

Your total vacation budget would be $280, considering the $160 spent on groceries and the estimated cost of eating out 3 times at $40 per meal from linear equation concept.

For your vacation at the beach, you have already spent $160 on groceries for the week. In addition, you anticipate spending $40 each time you eat out.

To determine your overall budget for the vacation, you need to consider how many times you plan to eat out during the week. Let's say you plan to eat out 'x' number of times.

Since each time you eat out costs $40, the total amount spent on eating out can be represented by the equation:

Total spent on eating out = $40 * x

Adding this to the amount spent on groceries, the total vacation budget can be calculated as:

Total budget = Amount spent on groceries + Total spent on eating out

Total budget = $160 + ($40 * x)

For example, if you plan to eat out 3 times during the week, the calculation would be:

Total budget = $160 + ($40 * 3)

Total budget = $160 + $120

Total budget = $280

In this case, your total vacation budget would be $280, considering the $160 spent on groceries and the estimated cost of eating out 3 times at $40 per meal.

The total budget will vary depending on the number of times you plan to eat out. By adjusting the value of 'x', you can calculate the specific total budget for your vacation.

The 40th percentile of the given data set is 3, which means that 40% of the data points are less than or equal to 3. The quartiles are Q1 = 3, median (Q2) = 7, and Q3 = 9.

To answer the questions, let's analyze the given data set step by step:

Find the 40th percentile:

To find the 40th percentile, we first need to arrange the data set in ascending order: 3, 3, 6, 8, 9, a+1, b+2, a+b. Since the values for 'a' and 'b' are not provided, we cannot determine their specific values. However, we can still find the 40th percentile by considering the given data points.

The 40th percentile represents the value below which 40% of the data falls. In this case, 40% of the data is (40/100) * 8 = 3.2. Since we have 8 data points, the 40th percentile falls between the second and third data points: 3 and 3. Therefore, the 40th percentile is 3.

Interpretation: The 40th percentile indicates that 40% of the data points in the set are less than or equal to 3.

Find the first quartile (Q1), median (Q2), and third quartile (Q3):

To find these quartiles, we still consider the same ordered data set: 3, 3, 6, 8, 9, a+1, b+2, a+b.

Q1 (first quartile): It represents the value below which 25% of the data falls. Since we have 8 data points, 25% of the data is (25/100) * 8 = 2. We can see that the second data point is 3, which is greater than 2. Therefore, Q1 is 3.

Q2 (median): It represents the middle value of the data set. Since we have an even number of data points, we take the average of the two middle values. In this case, the two middle values are 6 and 8. Therefore, the median is (6 + 8) / 2 = 7.

Q3 (third quartile): It represents the value below which 75% of the data falls. Similar to Q1, 75% of the data is (75/100) * 8 = 6. The sixth data point is 9, which is greater than 6. Therefore, Q3 is 9.

Sketch a boxplot for the data set:

To create a boxplot, we use the minimum value (3), Q1 (3), median (7), Q3 (9), and the maximum value (a+b). However, since the specific values of 'a' and 'b' are not provided, we cannot determine the exact position of the maximum value. Thus, we represent it as a+b on the boxplot. The boxplot will have a line across the box at the median (7), a box representing the interquartile range (Q1 to Q3), and "whiskers" extending from the box to the minimum value (3) and the maximum value (a+b).

b) 3-year subscriptions is approximately 29.56%.

c) 5-year subscriptions is approximately 41.33%.

To compute the rate of return on the investment for purchasers of different subscription lengths, we need to calculate the average annual cost of each subscription option.

a) 2-year subscriptions:

The cost of a 2-year subscription is $12.00. To find the average annual cost, we divide the total cost by the number of years:

Average annual cost = $12.00 / 2 = $6.00

b) 3-year subscriptions:

The cost of a 3-year subscription is $16.00. To find the average annual cost, we divide the total cost by the number of years:

Average annual cost = $16.00 / 3 = $5.33 (rounded to two decimal places)

c) 5-year subscriptions:

The cost of a 5-year subscription is $22.00. To find the average annual cost, we divide the total cost by the number of years:

Average annual cost = $22.00 / 5 = $4.40

Now, to calculate the rate of return on the investment, we need to compare the average annual cost to the regular 1-year subscription rate of $7.50.

a) For 2-year subscriptions:

Rate of return = (1 - Average annual cost / 1-year subscription rate) * 100%

Rate of return = (1 - $6.00 / $7.50) * 100% ≈ 20%

b) For 3-year subscriptions:

Rate of return = (1 - Average annual cost / 1-year subscription rate) * 100%

Rate of return = (1 - $5.33 / $7.50) * 100% ≈ 29.56%

c) For 5-year subscriptions:

Rate of return = (1 - Average annual cost / 1-year subscription rate) * 100%

Rate of return = (1 - $4.40 / $7.50) * 100% ≈ 41.33%

Therefore, the rate of return on the investment for purchasers of:

a) 2-year subscriptions is approximately 20%.
