Answer:

Below in bold.

Step-by-step explanation:

The right triangle of which ∅ is a part has

Hypotenuse = sqrt(8^2 + 15^2)

=  sqrt289

= 17,

So, sin ∅ = 8/17 and cos ∅ = 15/17

and

sin∅ + cos∅(1- cos∅)

= 8/17 + 15/17(1 - 15/17)

= 8/17 + 15/17 - 225/289

= 166/289.

(b)  tan 30 = h/96      where h is height of the mast

h = 96 tan 30.

12x - 15xy

Answer:

The answer is y=12x ÷ 1+15x

Step-by-step explanation:

Simplify and keep y on the left side

The minimum of x is 15, and the most is infinity, which is the same thing as [15, ∞).

We have given inequality is

–3(6 – 2x) ≥ 4x + 12

The statement of an order relationship greater than, greater than or equal to, less than, or less than or equal to between two numbers or algebraic expressions.

\(-3(6 - 2x) \geq 4x + 12\\-18 + 6x \geq 4x + 12\\6x - 4x \geq 12 + 18\\2x \geq 30\\x \geq 15\)

In this scenario, Ms. Garrett wants to select 10 students randomly from a school population of 1500 to have a lunch meeting . The sample, on the other hand, represents the specific group of 10 students

1. The population for this problem is the entire student body of the school, which consists of 1500 students. It includes all the individuals that Ms. Garrett could potentially select from.

2. The sample for this problem refers to the 10 students that Ms. Garrett will randomly select to participate in the lunch meeting. The sample is a subset of the larger population.

3. No, the sample of three to four student council members from each grade does not represent all the students in the school. It is a biased sample because it is specifically selecting students from a particular group (student council members) and not including students who are not part of the student council.

4. To ensure a truly random sample, Ms. Garrett should assign a unique number to each student in the school and then use a random number table or a random number generator to select 10 numbers.

The students corresponding to those numbers would be the randomly selected sample. This method would eliminate any bias and provide an equal chance for every student in the school to be selected for the lunch meeting, improving the representativeness of the sample.

The total number of apples, oranges, and tangerines in the fruit basket is in the ratio 10 or 10x

In mathematics, a ratio is a comparison of two or more numbers that indicates their sizes in relation to each other.

A ratio compares two quantities by division, with the dividend or number being divided termed the antecedent and the divisor or number that is dividing termed the consequent.

We know that : the ratio of apples : oranges : tangerines = 3 : 2 : 5.

The total number of apples, oranges, and tangerines in the fruit basket is the total number of ratio, that is 3 + 2 + 5 = 10.

Because of the question is not contain information about the number of pieces, we can describe the dividend with x (or unknown value). So, the total number of apples, oranges, and tangerines in the fruit basket with ratio, that is 10 or 10x.

The statements that only apply to C3, C4, and CAM photosynthesis are:

1. C3, C4, and CAM plants all have cells that have chloroplasts which attach CO2 directly to ribulose bisphosphate to produce sugars.

2. CAM plants have one set of cells that harvests CO2 and passes the carbon to another set of cells that builds sugars.

3. Stomata open at night to allow gas exchange and sugars are produced during the day.

The statement that applies to all three types of photosynthesis is: Light energy, CO2, and H20 are needed to make sugars.

C4 and CAM plants have adaptations that prevent the Calvin cycle from shutting down in periods of dryness. These adaptations include C4 plants using a carbon concentrating mechanism that separates the fixation of CO2 from the Calvin cycle and CAM plants using a process called crassulacean acid metabolism (CAM), where CO2 is taken up at night and stored as an acid until the following morning when it is converted into sugars in the Calvin cycle.

The process capability index Cpk for the provided process ≈ 0.7687.

To calculate the process capability index Cpk, we need to use the following formula:

Cpk = min((USL - μ) / (3 * σ), (μ - LSL) / (3 * σ))

where USL is the upper specification limit, LSL is the lower specification limit, μ is the process mean, and σ is the process standard deviation.

USL = 11.61 cm (upper specification limit)

LSL = 9.87 cm (lower specification limit)

μ = 10.85 cm (process mean)

σ = 0.33 cm (process standard deviation)

Substituting these values into the formula, we can calculate Cpk:

Cpk = min((11.61 - 10.85) / (3 * 0.33), (10.85 - 9.87) / (3 * 0.33))

Cpk = min(0.76 / 0.99, 0.98 / 0.99)

Cpk = min(0.7687, 0.9899)

Cpk = 0.7687 (rounded to four decimal places)

The solution to the system of equations is x = -22/35, y = 10/7, and z = 0.The system of equations represents three planes in three-dimensional space. It is found that the planes intersect at a unique point, resulting in a single solution.

We can solve the given system of equations using various methods, such as substitution or elimination. Let's use the method of elimination to find the solution.

First, we'll eliminate the variable x. We can do this by multiplying the second equation by 5 and the third equation by -5, then adding all three equations together. This results in the new system of equations:

5x - 2y - z = -6

5x - 5y - 10z = 0

-5x + 5y + 5z = 10

Simplifying the second and third equations, we have:

5x - 2y - z = -6

0x - 7y - 9z = -10

0x + 7y + 7z = 10

Next, we'll eliminate the variable y by multiplying the second equation by -1 and adding it to the third equation. This yields:

5x - 2y - z = -6

0x - 7y - 9z = -10

0x + 0y - 2z = 0

Now, we have a simplified system of equations:

5x - 2y - z = -6

-7y - 9z = -10

-2z = 0

From the third equation, we find that z = 0. Substituting this value back into the second equation, we can solve for y:

-7y = -10

y = 10/7

Finally, substituting the values of y and z into the first equation, we can solve for x:

5x - 2(10/7) - 0 = -6

5x - 20/7 = -6

5x = -6 + 20/7

5x = -42/7 + 20/7

5x = -22/7

x = -22/35

Therefore, the solution to the system of equations is x = -22/35, y = 10/7, and z = 0. These values represent the intersection point of the three planes in three-dimensional space.

Samuel's opportunity cost of going to the ball game is $15.To calculate Samuel's opportunity cost of going to the ball game, we need to consider the value of the next best alternative he is giving up,

which in this case is working at his job.

Given:

Time off from work: 4 hours

Ticket cost: $20

Parking cost: $5

Hourly wage: $10

The opportunity cost can be calculated by considering the earnings Samuel would have made if he had worked instead of going to the baseball game.

The earnings from working for 4 hours would be:

Earnings = Hourly wage * Time

Earnings = $10 * 4

Earnings = $40

In addition to the lost earnings, we need to consider the expenses related to attending the game. The total expenses are:

Expenses = Ticket cost + Parking cost

Expenses = $20 + $5

Expenses = $25

Therefore, Samuel's opportunity cost of going to the ball game is the combination of lost earnings and expenses by formula:

Opportunity cost = Earnings - Expenses

Opportunity cost = $40 - $25

Opportunity cost = $15

Thus, Samuel's opportunity cost of going to the ball game is $15.

The student covers a total distance of 22.05 kilometers in a week's time, walking between the park and the house each day.

To find the total distance covered by the student in a week's time, we need to calculate the distance covered in one round trip (from the house to the park and back) and then multiply it by the number of round trips in a week.

Given that the difference between the park and house is 1 kilometer and 575 meters, we can convert it to a total distance of 1.575 kilometers.

In a round trip, the student covers twice the distance between the park and the house, which is 1.575 kilometers * 2 = 3.15 kilometers.

Now, we need to determine how many round trips the student makes in a week. Let's assume the student makes one round trip each day.

Since there are 7 days in a week, the total distance covered by the student in a week's time is 3.15 kilometers * 7 = 22.05 kilometers.

The binomial that is required for the two polynomials is 4r - 19

To find the binomial that must be added to (2r+12) so that the sum of two polynomials is (6r-7), we can subtract (2r+12) from (6r-7) and see what we get.

(6r-7) - (2r+12) = 4r - 19

This tells us that the binomial that must be added to (2r+12) is (4r-19).

To check our answer, we can add (4r-19) to (2r+12) and see if we get (6r-7).

(2r+12) + (4r-19) = 6r - 7
