The interpolating polynomial  is (a) p(t) = 13 - 2.5t +1.5t²

From the question, we have the following parameters that can be used in our computation:

Points =  (1, 13), (2, 14), and (3, 19).

Using the general form of the quadratic formula, we have

a + b + c = 12

5a + b = 5

Subtract the equations to eliminate b

So, we have

2a = 3

So, we have

a = 1.5

Next, we have

3a + b = 2

3(1.5) + b = 2

Evaluate

b = -2.5

Lastly, we have

4a + 2b + c = 14

4(1.5) + 2(-2.5) + c = 14

To find the total cost of office supplies, applying the order of operations (PEMDAS) is crucial. A stapler priced at $8 and 5 pens, each costing $2, are required. By following the correct order, we calculate the cost of the stapler separately, then the pens. Adding the stapler cost ($8) to the pen cost ($10) yields a total of $18. Adhering to the order of operations ensures accurate calculations and determines the correct total cost of the supplies.

To solve the problem, let's demonstrate the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

The correct method to solve the problem is as follows:

1. Calculate the cost of the stapler: $8.

2. Calculate the cost of the pens: 5 pens * $2/pen = $10.

3. Add the cost of the stapler and the pens to find the total cost: $8 + $10 = $18.

Therefore, the total cost of the supplies for the office is $18.

Now, let's demonstrate the incorrect method by not following the order of operations:

1. Add the cost of the stapler and the pens first: $8 + (5 * $2).

2. Perform the multiplication: $8 + (5 * $2) = $8 + $10 = $18.

In this case, the incorrect method led to the same result as the correct method. However, this may not always be the case. If the order of operations is not followed correctly, it can lead to incorrect results.

It is essential to follow the order of operations to ensure accurate calculations. Parentheses should be evaluated first, followed by exponents, multiplication and division (from left to right), and finally addition and subtraction (from left to right).

By correctly following the order of operations, we can obtain the accurate total cost of the supplies for the office, which is $18.

The vector function that represents the curve of intersection between the cone z = sqrt[tex](x^2 + y^2[/tex]) and the plane z = 1 is given by r(t) = [cos(t), sin(t), 1]

To find the vector function that represents the curve of intersection between the cone and the plane, we need to equate the expressions for z in both surfaces and solve for x, y, and z.

The cone is defined by the equation z = sqrt([tex]x^2 + y^2).[/tex]

The plane is defined by the equation z = 1.

Setting these two expressions equal to each other, we have:

sqrt(x^2 + y^2) = 1

To eliminate the square root, we can square both sides of the equation:

[tex]x^2 + y^2 = 1[/tex]

This equation represents a circle in the xy-plane with a radius of 1 centered at the origin.

Now, let's express x and y in terms of a parameter t to obtain a vector function for the curve of intersection. We can choose to parameterize the circle using polar coordinates:

x = cos(t)

y = sin(t)

Substituting these expressions into the equation x^2 + y^2 = 1, we have:

cos^2(t) + sin^2(t) = 1

This is true for any value of t, so the parameterization is valid.

Finally, we can write the vector function for the curve of intersection:

r(t) = [cos(t), sin(t), 1]

Therefore, the vector function that represents the curve of intersection between the cone z = sqrt(x^2 + y^2) and the plane z = 1 is given by r(t) = [cos(t), sin(t), 1], where t is a parameter that varies over the range of values that defines the circle in the xy-plane.

To determine the amount of glycerine needed for the preparation of 96 suppositories, we need to calculate the amount of glycerine used per suppository and then scale it up for the total number of suppositories.

Glycerine: 91g

Sodium stearate: 9g

Purified water: 5g

Since we are making 50 suppositories, we can calculate the amount of glycerine per suppository as:

Amount of glycerine per suppository = Glycerine / Number of suppositories

Amount of glycerine per suppository = 91g / 50

Amount of glycerine per suppository = 1.82g

Now, we can scale this up to find the amount of glycerine needed for 96 suppositories:

Total amount of glycerine = Amount of glycerine per suppository * Number of suppositories

Total amount of glycerine = 1.82g [tex]\times[/tex] 96

Total amount of glycerine = 174.72g

However, we need to convert this weight to volume using the specific gravity of glycerine.

The z-score for a student who earned a 75 on the history test is -5/6.

To calculate the z-score for a student who earned a 75 on the history test, we need to use the formula:

z = (x - μ) / σ

Where:

x is the individual score (75 in this case),

μ is the population mean (average) of the scores (80),

and σ is the standard deviation of the scores (6).

Plugging in the values, we have:

z = (75 - 80) / 6

Simplifying the equation:

z = -5 / 6

Therefore, the z-score for a student who earned a 75 on the history test is -5/6.

The z-score represents the number of standard deviations a particular data point is away from the mean.

In this case, since the z-score is negative (-5/6), it indicates that the student's score of 75 is below the mean score of 80. The magnitude of the z-score (5/6) suggests that the student's score is approximately 0.83 standard deviations below the mean.

Z-scores are useful in comparing individual scores to the distribution of scores.

They provide a standardized measure of how a data point relates to the mean and standard deviation of a dataset. In this case, the negative z-score indicates that the student's score is below average, and the magnitude of the z-score gives a sense of the deviation from the mean.

There is no unique output for the manufacturing sector that can satisfy the given final demand for transportation and manufacturing.

To determine the output for the manufacturing sector, we can set up a system of equations based on the given information. Let's denote the output for the transportation sector as T and the output for the manufacturing sector as M.

From the given information, we know that:

- Production of a dollar's worth of transportation requires an input of $0.20 from transportation and $0.15 from manufacturing.

- Production of a dollar's worth of manufacturing requires an input of $0.40 from transportation and $0.30 from manufacturing.

Using these statements, we can set up the following equations:

0.20T + 0.15M = $60 million (equation 1)

0.40T + 0.30M = $80 million (equation 2)

We can solve this system of equations to find the values of T and M

Multiplying equation 1 by 2, we have:

0.40T + 0.30M = $120 million (equation 3)

Now, subtracting equation 2 from equation 3, we get:

(0.40T + 0.30M) - (0.40T + 0.30M) = $120 million - $80 million

This simplifies to:

0 = $40 million

This means that the left-hand side of the equation is zero, and there is no valid solution that satisfies both equations simultaneously.

Therefore, there is no unique output for the manufacturing sector that can satisfy the given final demand for transportation and manufacturing. The given information seems to be inconsistent or incomplete.

It's important to note that the problem could be resolved by providing additional information or correcting any errors in the given data. Without further clarification, it is not possible to determine the output for the manufacturing sector.

The value of f(g(-2)) - 150 is -138.

To find the value of f(g(-2)), we first need to substitute -2 into the function g(x) and then use the result as the input for the function f(x).

Let's start with g(-2). Plugging -2 into the function g(x) gives us:

g(-2) = (-2)^2 + 2

= 4 + 2

= 6

Now, we have the value of g(-2) as 6. Next, we substitute this value into the function f(x):

f(g(-2)) = f(6) = -1/2(6)^2 + 5(6)

= -1/2(36) + 30

= -18 + 30

= 12

Finally, we have found that f(g(-2)) is equal to 12. To find the value of f(g(-2)) - 150, we subtract 150 from the value we obtained:

f(g(-2)) - 150 = 12 - 150

= -138

Therefore, the value of f(g(-2)) - 150 is -138.
