The value Newton's interpolating polynomial P 2(x) of f(x) of f[x0, x1] is -4.

In Newton's interpolating polynomial, the coefficients of the linear terms (x) correspond to divided differences. The divided difference f[x0, x1] represents the difference between the function values f(x0) and f(x1) divided by the difference between x0 and x1.

Since we are given P2(x) = \(x^2 + x + 2\), we can substitute the given x-values into P2(x) to find the corresponding function values.

For x0 = -3, substituting into P2(x) gives f(-3) = \((-3)^2 + (-3) + 2 = 12\).

For x1 = 1, substituting into P2(x) gives f(1) = \((1)^2 + (1) + 2 = 4\).

To calculate f[x0, x1], we need to find the divided difference between these two function values: f[x0, x1] = (f(x1) - f(x0)) / (x1 - x0) = (4 - 12) / (1 - (-3)) = -8 / 4 = -2.

Therefore, f[x0, x1] = -2, and the correct answer choice is b. -4.

The most appropriate choice for unitary method will be given by-

a) Mass of 100 \(cm^3\) of the material = 1000 g

b) Mass of 500 \(cm^3\) of the material = 5000 g

What is unitary method?

Unitary method is the process in which the value of single unit can be calculated from the value of multiple unit and the value of multiple unit can be calculated from the value of single unit.
Sometimes Value of single unit can be less than the value of multiple unit. For example - The relation between the cost of a commodity and the quantity of the commodity

Sometimes Value of single unit can be more than the value of multiple unit. For example - The relation between the number of men and the number of days taken by those men to do a certain job.

Here,

a)Mass of \(9 cm^3\) of samples = 90 g

Mass of 1 \(cm^3\) of sample = \(\frac{90}{9}\) g

Mass of 1 \(cm^3\) of sample = 10 g

Mass of 100 \(cm^3\) of sample = \(10 \times 100 g\) = 1000 g

b) Mass of 500 \(cm^3\) of sample = \(10 \times 500\) g = 5000 g

The required number of children and adults for sitting in the theater are 300 and 50 respectively.

A equation is supposed to be linear equation in two factors in the event that it is written as hatchet + by + c=0, where a, b and c are genuine numbers and the coefficients of x and y, i.e an a and b separately, are not equivalent to nothing. For instance, 10x+4y = 3 and - x+5y = 2 are straight equation in two factors.

Let be consider number of children be x and that of adults is y.

We have,

x + y = 350-------(1)

y = 350 - x

And 5x + 10y = 2000------------------(2)

Put value of y in equation (2)

5x + 10( 350 - x) = 2000

5x + 3500 - 10x = 2000

-5x = -1500

x = 300

Then

y = 350 - x = 350 - 300 = 50

Thus, There will be 300 children and 50 adults in the  theater .

=============================================================

Explanation:

The tree's shadow is 120 ft long, so it's the length of the horizontal side of the triangle. With regard to the reference angle (47 degrees), this 120 ft side is adjacent to the angle because it's as close as possible to the angle. That means the X is the opposite side of the reference angle.

The Y side is the longest side. It's the hypotenuse. The hypotenuse is always the longest side and always opposite the largest angle of a right triangle (so it's always opposite the 90 degree angle).

-------------

To find Y, we'll use the cosine rule

cos(angle) = adjacent/hypotenuse

cos(47) = 120/Y

Y*cos(47) = 120

Y = 120/cos(47)

Y = 175.9535 .... make sure your calc is in degree mode

Y = 176.0

When rounding to the nearest tenth, the second '5' will bump that 9 up to 10, which then carries over and why 175 bumps up to 176.

The distance from the tip of the tree to the tip of the shadow is roughly 176 feet.

-------------

We can use the tangent rule to find X

tan(angle) = opposite/adjacent

tan(47) = X/120

120*tan(47) = X

X = 120*tan(47)

X = 128.6842

X = 128.7

The tree is roughly 128.7 feet tall

This is somewhere between a 12 story and 13 story building assuming each story is 10 ft (since 12 stories = 12*10 = 120 ft, and 13 stories = 130 ft).

Answer: So there are three ways...

$850=150(1)+100(7)

$850=150(3)+100(4)

$850=150(5)+100(1)

Step-by-step explanation:

The equation is 150x+100y=850 where x and y are any whole number of items that she was able to purchase with $850

So there are three ways...

$850=150(1)+100(7)

$850=150(3)+100(4)

$850=150(5)+100(1)

These are the purchases where x is pens and y is pencils

To show the converse of the Pythagorean theorem using side lengths chosen from 5 cm, 9 cm, 12 cm, and 13 cm  the procedure that can be used is : C. Knowing that 52 + 122 = 132, draw the 5 cm side and the 12 cm side with a right angle between them. The 13 cm side will fit to

form a right triangle.

In Option C, we are given the lengths 5 cm, 9 cm, 12 cm, and 13 cm. The converse of the Pythagorean theorem states that if the square of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.

In this case, we have 52 + 122 = 132, which satisfies the condition for a right triangle according to the Pythagorean theorem.

By drawing the 5 cm side and the 12 cm side with a right angle between them, we can see that the 13 cm side will fit perfectly to form a right triangle. This demonstrates the converse of the Pythagorean theorem.

Option C is the correct procedure to show the converse of the Pythagorean theorem using the given side lengths.

To determine the probability that an ADA will earn between $50 and $60 per hour, we can use the standard normal distribution and the z-score.

Given:

Mean (μ) = $52

Standard deviation (σ) = $5.50

To find the probability, we need to calculate the z-scores for the lower and upper limits, and then use the z-table or a calculator to find the corresponding probabilities.

Step 1: Calculate the z-scores

For the lower limit of $50:

z_lower = (X_lower - μ) / σ = (50 - 52) / 5.50

For the upper limit of $60:

z_upper = (X_upper - μ) / σ = (60 - 52) / 5.50

Step 2: Look up the probabilities from the z-table or use a calculator

Using the z-table or a calculator, we can find the probabilities corresponding to the z-scores.

Let's denote the probability for the lower limit as P1 and the probability for the upper limit as P2.

Step 3: Calculate the final probability

The probability that an ADA will earn between $50 and $60 per hour is the difference between P2 and P1.

P(X_lower < X < X_upper) = P2 - P1

Note: Make sure to use the cumulative probabilities (area under the curve) from the z-table or calculator.

Now the value of m will be,

→ (2m - 27)/3 = 5m

→ 2m - 27 = 5m × 3

Hence, value of m is -27/13.

No, the lines cannot ever match up perfectly because there is always some sort of difference between them. The lines can have the same slope if they have the same change in y-values for a given change in x-values. The lines can also have the same y-intercept if they cross the y-axis at the same point.

No, there will never be a perfect alignment between the lines since there will always be a discrepancy of some kind. However, the lines can have the same slope and y-intercept. This is possible because the slope and y-intercept are determined by the equation of the line, and if two lines have the same equation, then they will have the same slope and y-intercept.

If the lines intersect the y-axis at the same location, they can also have the same y-intercept. This means that the two lines have the same value of b in the equation y = mx + b. This means that the two lines have the same slope and the same y-intercept.

(f - g)(x) = f(x) - g(x)

(f - g)(x) = ( f(x) ) -  ( g(x) )

(f - g)(x) = (4x^2 - 6) - ( x^2 - 4x - 8)

(f - g)(x) = 4x^2 - 6 - x^2 + 4x + 8

The height of right cone is roughly 60.58 units .

We can use the formula for a cone's volume and play around with it to solve for the height in order to determine a right cone's height given its volume and diameter. V = (1/3) * * r2 * h, where V is the volume, r is the radius (half the diameter), and h is the height, is the formula for a cone's volume.

By dividing the cone's 18-unit diameter by 2, we can determine the radius, which comes out to r = 18/2 = 9 units.

Now that we know the quantities, we can enter them into the volume formula: \(5137 = (1/3) * * 9^2 * h.\)

We can rewrite the equation as follows to find h:

\(h = (3 * V) / (\pi * r^2)\)

If we substitute the values provided, we get:h =\((3 * 5137) / (\pi * 9^2)\)

When we evaluate the expression using the approximation of 3.14159 for, we get the following result: h (3 * 5137) / (3.14159 * 81)

h ≈ 15411 / 254.469

h=60.58 units

Main answer will be |A| = 9 and |B| = 0.

From the given facts, we can deduce the following:

|P(A × B)| = 1,048,576: The cardinality of the power set of the Cartesian product of A and B is 1,048,576. This means that the total number of subsets of A × B is 1,048,576.

|A| > |B|: The cardinality of set A is greater than the cardinality of set B. In other words, there are more elements in set A than in set B.

|A ∪ B| = 9: The cardinality of the union of sets A and B is 9. This means that there are a total of 9 unique elements in the combined set A ∪ B.

A ∩ B = ∅: The intersection of sets A and B is empty, indicating that they have no common elements.

Based on these facts, we can determine that |A| = 9 because the cardinality of the union of A and B is 9. This means that set A has 9 elements.

Since A ∩ B = ∅ (empty set), it implies that set B has no elements in common with set A. Therefore, |B| = 0, indicating that set B is an empty set.
