To derive the interpolating polynomial using the Newton divided difference formula, we can follow these steps:

Step 1: Create a divided difference table

x f(x)

0 -1

1 1

2 9

3 29

5 129

Step 2: Calculate the divided differences

First-order divided differences:

f[x0, x1] = (f(x1) - f(x0)) / (x1 - x0) = (1 - (-1)) / (1 - 0) = 2

f[x1, x2] = (f(x2) - f(x1)) / (x2 - x1) = (9 - 1) / (2 - 1) = 8

f[x2, x3] = (f(x3) - f(x2)) / (x3 - x2) = (29 - 9) / (3 - 2) = 20

f[x3, x4] = (f(x4) - f(x3)) / (x4 - x3) = (129 - 29) / (5 - 3) = 50

Second-order divided differences:

f[x0, x1, x2] = (f[x1, x2] - f[x0, x1]) / (x2 - x0) = (8 - 2) / (2 - 0) = 3

f[x1, x2, x3] = (f[x2, x3] - f[x1, x2]) / (x3 - x1) = (20 - 8) / (3 - 1) = 6.

Third-order divided differences:

f[x0, x1, x2, x3] = (f[x1, x2, x3] - f[x0, x1, x2]) / (x3 - x0) = (6 - 3) / (3 - 0) = 1

Fourth-order divided differences:

f[x0, x1, x2, x3, x4] = (f[x1, x2, x3, x4] - f[x0, x1, x2, x3]) / (x4 - x0) = (50 - 1) / (5 - 0) = 10.2

Step 3: Build the interpolating polynomial

The interpolating polynomial can be written as:

P(x) = f(x0) + f[x0, x1](x - x0) + f[x0, x1, x2](x - x0)(x - x1) + f[x0, x1, x2, x3](x - x0)(x - x1)(x - x2) + ... + f[x0, x1, x2, x3, x4](x - x0)(x - x1)(x - x2)(x - x3)

Using the values from the divided differences table, we have:

P(x) = -1 + 2(x - 0) + 3(x - 0)(x - 1) + 1(x - 0)(x - 1)(x - 2) + 10.2(x - 0)(x - 1)(x - 2)(x - 3)

Simplifying:

[tex]P(x) = -1 + 2x + 3x^2 - 3x + x^3 - 3x^2 + 6x - 2x^3 + 10.2x^4 - 30.6x^3 + 30.6x^2 - 10.2x[/tex]

[tex]P(x) = -1 + 2x + x^3 - 2x^3 + 10.2x^4 - 30.6x^3 + 30.6x^2 - 10.2x\\P(x) = -1 - x^3 + 8.2x^4 - 30.6x^3 + 30.6x^2 - 7.2x[/tex]

Step 4: Compute the value of y(4)

To find the value of y(4), we substitute x = 4 into the interpolating polynomial:

[tex]P(4) = -1 - (4)^3 + 8.2(4)^4 - 30.6(4)^3 + 30.6(4)^2 - 7.2(4)[/tex]

P(4) = -1 - 64 + 8.2(256) - 30.6(64) + 30.6(16) - 28.8

P(4) = -1 - 64 + 2099.2 - 1958.4 + 489.6 - 28.8

P(4) = 636.6

Therefore,

The value of y(4) is 636.6.

In this step, we need to find the x-intercepts where the polynomial function f(x) = (x+4)²(x - 3)³(x - 2) crosses the x-axis. We are asked to select the number of x-intercepts and provide them as ordered pairs.

To find the x-intercepts of the polynomial function f(x) = (x+4)²(x - 3)³(x - 2), we set the function equal to zero and solve for x.

Setting f(x) = 0, we have (x+4)²(x - 3)³(x - 2) = 0. By applying the zero-product property, we can set each factor equal to zero and solve for x separately.

Thus, we set (x+4) = 0, (x - 3) = 0, and (x - 2) = 0. Solving these equations, we find three distinct x-intercepts: x = -4, x = 3, and x = 2.

Therefore, the function f(x) crosses the x-axis at these three points. Expressing them as ordered pairs, the intercepts are (-4, 0), (3, 0), and (2, 0).

The value of the trigonometric function sin(θ/2) is 7/√85.

To find sin(θ/2), we can use the half-angle formula for sine:

sin(θ/2) = ±√((1 - cosθ) / 2)

Given that tanθ = 84/13 and π < θ < 3π/2, we can use the given information to determine the value of cosθ.

Using the identity tanθ = sinθ / cosθ, we can rewrite the given equation:

tanθ = 84/13

sinθ / cosθ = 84/13

sinθ = (84/13)cosθ

Now, let's use the Pythagorean identity sin²θ + cos²θ = 1 to solve for cosθ:

(84/13)cosθ = sinθ

(84/13)²cos²θ + cos²θ = 1

(7056/169)cos²θ + cos²θ = 1

[(7056 + 169) / 169]cos²θ = 1

(7225/169)cos²θ = 1

cos²θ = 169/7225

cosθ = ±√(169/7225)

cosθ = ±(13/85)

Since π < θ < 3π/2, we are in the fourth quadrant, where the cosine is negative. Therefore, cosθ = -13/85.

Substituting the value of cosθ into the half-angle formula for sine:

sin(θ/2) = ±√((1 - cosθ) / 2)

= ±√((1 - (-13/85)) / 2)

= ±√((85 + 13) / (2 * 85))

= ±√(98/170)

= ±√(49/85)

= ±(7/√85)

Since θ is in the fourth quadrant, sin(θ/2) is positive.

Therefore, sin(θ/2) = 7/√85.

b. f(0.6) ≈ 0.6, maximum error is approximately 0.02352.

Consider the following common approximation when x is near zero: sin(x) ≈ x when x is near 0.

Using this approximation, we need to estimate f(0.2) and f(0.6) and find the maximum error in the approximation using n = 2.

a. To estimate f(0.2), we substitute x = 0.2 in the approximation: sin(0.2) ≈ 0.2

We need to find the maximum error in the approximation using n = 2.

For this, we use the formula for the error term in the Taylor series expansion of

sin(x): |R2(x)| ≤ M|x|³/3!

where M is a bound for the third derivative of sin(x) in the interval [0, 0.2].

The third derivative of sin(x) is cos(x), and its absolute value is less than or equal to 1 in the given interval.

Thus, we can take M = 1.

Substituting x = 0.2 and n = 2 in the above formula, we get:

|R2(0.2)| ≤ 1 × (0.2)³/(3!)≈ 0.00022 (rounded to five decimal places)

Therefore, the maximum error is approximately 0.00022.

b. To estimate f(0.6), we substitute x = 0.6 in the approximation:

sin(0.6) ≈ 0.6

We need to find the maximum error in the approximation using n = 2.

For this, we use the same formula for the error term as before:

|R2(x)| ≤ M|x|³/3!

where M is a bound for the third derivative of sin(x) in the interval [0, 0.6].

The third derivative of sin(x) is cos(x), and its absolute value is less than or equal to 1 in the given interval.

Thus, we can take M = 1.

Substituting x = 0.6 and

n = 2 in the above formula, we get:

|R2(0.6)| ≤ 1 × (0.6)³/(3!)≈ 0.02352 (rounded to five decimal places)

The instantaneous velocity of the object at time t = 2 is -5. we have used the formula `ds/dt` to find the instantaneous velocity at time t=2. The instantaneous velocity of an object is the rate of change of its displacement with respect to time and is given by the derivative of the displacement function with respect to time.

Given, the position of an object moving in a straight line is given by s(t)=21²-5t-9.

To find the instantaneous velocity at time t = 2,

we have to differentiate the given position function with respect to t.

Let's differentiate the given position function s(t) using the power rule of differentiation below: `s(t) = 21t² - 5t - 9`Differentiate s(t) with respect to t.` ds/dt = d/dt(21t²) - d/dt(5t) - d/dt(9)`

a. The standard deviation of a random variable is a measure of how spread out its values are. For a random variable X with distribution (µ, σ), where µ is the mean and σ is the standard deviation, the standard deviation of X is equal to σ.

In this case, the random variable 1 has a distribution (10,4). Therefore, the standard deviation of 1 is 4.

b. To find the mean of a random variable, we simply use the value of µ from the distribution. In this case, the random variable 1 has a distribution (10,4), so the mean is 10.

c. If n = 20, we have a sum of 20 independent and identically distributed random variables with distribution (10,4). The sum of independent and identically distributed random variables follows a normal distribution with mean equal to the sum of the means of the individual variables, and standard deviation equal to the square root of the sum of the variances of the individual variables.

Since each variable has mean 10 and standard deviation 4, the mean of the sum is 20 * 10 = 200. The standard deviation of the sum is √(20 * 4^2) = √(320) ≈ 17.89.

Therefore, () is approximately N(200, 17.89).

d. To compute the probability that  will be between 9.6 and 10.4 for n = 20, we need to find the probability that the sum of 20 independent and identically distributed random variables with distribution (10,4) falls within that range.

Since the sum of independent and identically distributed random variables follows a normal distribution, we can use the properties of the normal distribution to calculate this probability.

First, we need to standardize the range 9.6 to 10.4. We subtract the mean (200) and divide by the standard deviation (17.89) to get the z-scores for the lower and upper bounds:

Lower z-score: (9.6 - 200) / 17.89 ≈ -10.03
Upper z-score: (10.4 - 200) / 17.89 ≈ -9.96

Using a standard normal distribution table or a calculator, we can find the probabilities associated with these z-scores:

P(Z < -10.03) ≈ 0
P(Z < -9.96) ≈ 0

The probability that  will be between 9.6 and 10.4 for n = 20 is the difference between these probabilities:

P(9.6 <  < 10.4) ≈ P(Z < -9.96) - P(Z < -10.03) ≈ 0 - 0 ≈ 0

Therefore, the probability that  will be between 9.6 and 10.4 for n = 20 is approximately 0.

a. The graph of g(x) is a curve that starts at (0, 4), approaches negative infinity as x approaches negative infinity, and approaches positive infinity as x approaches positive infinity. b. Domain: [0, +∞); Range: (-∞, +∞). c. Increasing: (0, +∞); Decreasing: [-2, 0). d. Concave up: [-2, 0) and (0, +∞).

a. To sketch the graph of the function g(x) = x²√x - x + 4, we can start by analyzing its behavior and key points.

First, let's find the x-intercepts by setting g(x) = 0:

0 = x²√x - x + 4

Unfortunately, this equation cannot be easily solved analytically. However, we can still determine the behavior of the function by analyzing the leading terms. As x approaches negative infinity, x²√x dominates the other terms, and since x²√x approaches negative infinity, we can infer that the graph will approach negative infinity as x approaches negative infinity.

Similarly, as x approaches positive infinity, x²√x dominates the other terms, and since x²√x approaches positive infinity, we can infer that the graph will approach positive infinity as x approaches positive infinity.

Next, let's find the y-intercept by setting x = 0:

g(0) = 0²√0 - 0 + 4 = 4

Therefore, the function g(x) has a y-intercept at (0, 4).

Now, let's find the critical points by taking the derivative of g(x) and setting it equal to zero:

g'(x) = d/dx (x²√x - x + 4)

      = 2x√x + x^(3/2) - 1

Setting g'(x) = 0:

0 = 2x√x + x^(3/2) - 1

Unfortunately, this equation also cannot be easily solved analytically. However, we can still determine the behavior of the function by analyzing the leading terms. As x approaches negative infinity, x^(3/2) dominates the other terms, and since x^(3/2) approaches negative infinity, we can infer that the graph will be decreasing as x approaches negative infinity.

Similarly, as x approaches positive infinity, x^(3/2) dominates the other terms, and since x^(3/2) approaches positive infinity, we can infer that the graph will be increasing as x approaches positive infinity.

From this analysis, we can sketch a rough graph of g(x) as follows:

    +---|---+

    |   |   |

    |   |   |

    |   |   |

-----|---|---|---|--->

    |   |   |

    +---|---+

        |

        v

b. Domain: The domain of g(x) is determined by the values of x for which the function is defined. In this case, the function involves square roots, so the radicand (x) must be non-negative.

Therefore, the domain of g(x) is [0, +∞).

Range: To determine the range of g(x), we need to analyze the behavior of the function. As x approaches negative infinity, the function approaches negative infinity, and as x approaches positive infinity, the function approaches positive infinity.

Hence, the range of g(x) is (-∞, +∞).

c. Increasing and Decreasing Intervals: To determine the intervals on which g(x) is increasing or decreasing, we need to analyze the behavior of the derivative g'(x).

For -2 ≤ x < 0:

g'(x) < 0 for all x in this interval, indicating that g(x) is decreasing on the interval [-2, 0).

For 0 < x < 4:

g'(x) > 0 for all x in this interval, indicating that g(x) is increasing on the interval (0

, 4).

For x > 4:

Since we know g(x) approaches positive infinity as x approaches positive infinity, we can infer that g(x) continues to increase on this interval.

Therefore, g(x) is decreasing on the interval [-2, 0) and increasing on the interval (0, +∞).

d. Concave Up and Concave Down: To determine the intervals on which g(x) is concave up or concave down, we need to analyze the behavior of the second derivative g''(x).

g''(x) = d/dx (2x√x + x^(3/2) - 1)

      = 2√x + (3/2)x^(1/2)

For -2 ≤ x < 0:

Since x is negative in this interval, the term 2√x is undefined. However, the term (3/2)x^(1/2) is well-defined and positive, indicating that g(x) is concave up on the interval [-2, 0).

For 0 < x < 4:

Both terms 2√x and (3/2)x^(1/2) are well-defined and positive, indicating that g(x) is concave up on the interval (0, 4).

For x > 4:

Since we know g(x) is increasing on this interval, we can infer that g(x) continues to be concave up.

Therefore, g(x) is concave up on the intervals [-2, 0) and (0, +∞).

e. To solve g(x) = 0, we need to find the x-values where the graph of g(x) intersects the x-axis. From the graph, we can see that there are two such points, which correspond to the x-intercepts:

x ≈ -1.7 and x ≈ 0.9

f. To determine the number of solutions to the equation g(x) = 2, we need to examine the graph of g(x) and see how many times it intersects the horizontal line y = 2. From the given information, we don't have enough details to accurately determine the number of solutions without the graph or additional information.

g. To calculate the average rate of change of g(x) on the interval [1, 4], we can use the formula:

Average Rate of Change = (g(4) - g(1)) / (4 - 1)

Calculate g(4) and g(1) by substituting the values into the function:

We see that there is only one 36, so the third smallest value is 36. Thus, the answer is D, 2600.

The third smallest value can be found by scanning the plot from left to right, which shows the leaf units in ascending order. To get the smallest value, we look for the smallest leaf unit in the plot.

2 is the smallest leaf unit in this plot.

The first and second smallest values are determined in the same manner as the smallest value, however, in order to determine the third smallest value, we have to skip past two values to arrive at the third smallest value.

The stem-and-leaf plot provided shows the values of the data in ascending order, with the smallest values on the left and the largest on the right.

To determine the smallest value in the plot, look for the smallest leaf unit, which in this case is 2. The smallest value, then, is 21. To determine the second smallest value, we must look for the next smallest leaf unit after 2, which is 4.

We see from the plot that there are two 34s, so the second smallest value is 34.

To determine the third smallest value, we must skip the two values that we have already found and look for the next smallest leaf unit after 4, which is 6.

We see that there is only one 36, so the third smallest value is 36. Thus, the answer is D, 2600.

(a) The semiannual payment to amortize this loan is $517.42

(b) total amount of the payments is $1813.56

(c) total payment from the amortization table is $9313.56, and the total interest paid is $1813.56.

To calculate the semiannual payment, total payments, total interest paid, and the amortization table for the given loan, use the formula for calculating the payment amount on an amortizing loan:

Payment = Principal × (r × (1 + r)ⁿ) / ((1 + r)ⁿ - 1)

Where:

Principal = $7500 (loan amount)

r = interest rate per compounding period = 6.9% / 2 = 0.069 / 2 = 0.0345 (since the interest is compounded semiannually)

n = total number of compounding periods = 18

(a) Calculate the semiannual payment:

Payment = $7500 × (0.0345 × (1 + 0.0345)¹⁸) / ((1 + 0.0345)¹⁸ - 1)

Payment ≈ $517.42

(b) Calculate the total payments:

Total payments = Payment × n

Total payments ≈ $517.42 × 18

Total payments ≈ $9313.56

To calculate the total amount of interest paid, subtract the loan amount from the total payments:

Total interest paid = Total payments - Principal

Total interest paid ≈ $9313.56 - $7500

Total interest paid ≈ $1813.56

(c) To create an amortization table, calculate the payment schedule for each compounding period and track the remaining balance. Here is the amortization table:

Answer:

Let's use the following variables to represent the length and width of the rectangle:

L = length

W = width

We know that the length is three times the width, so we can write:

L = 3W

We also know that the perimeter of a rectangle is given by:

P = 2L + 2W

We're given that the perimeter of this rectangle is 44 cm, so we can write:

44 = 2L + 2W

Now we can substitute the expression for L in terms of W:

44 = 2(3W) + 2W

Simplifying the right side:

44 = 6W + 2W

44 = 8W

Dividing both sides by 8:

W = 5.5

So the width of the rectangle is 5.5 cm. To find the length, we can use the expression we derived earlier for L in terms of W:

L = 3W = 3(5.5) = 16.5

So the length of the rectangle is 16.5 cm.

To find the area of the rectangle, we can use the formula:

A = L * W

Substituting the values we found:

A = 16.5 * 5.5 = 90.75

So the area of the rectangle is 90.75 square centimeters.

hope it helps you

Answer:

the width of the rectangle is 5.5 cm and its area is 90.75 cm².

Step-by-step explanation:

The formula for the perimeter of a rectangle is given by:

Perimeter = 2(length + width)

44 = 2(3w + w)

Now, we can solve for the width "w" by simplifying and solving the equation:

44 = 2(4w)

44 = 8w

w = 44/8

w = 5.5 cm

Length = 3w = 3(5.5) = 16.5 cm

Area = length × width

Substituting the values, we have:

Area = 16.5 × 5.5 = 90.75 cm²

If LO≅LM and OP≅ PM, then the correct conclusion would be ΔLMP ≅ ΔLOP by SSS.

In the given statement, it is clear that LO and LM are congruent while OP and PM are congruent.

Here, by Side-Side-Side (SSS) congruency theorem, ΔLMP and ΔLOP are congruent as all the three sides of these two triangles are equal.

Therefore, the correct conclusion would be ΔLMP ≅ ΔLOP by SSS.
SSS congruency theorem is one of the congruency theorems which states that if three sides of one triangle are congruent to the three sides of the other triangle, then the two triangles are congruent.

In this theorem, all the three sides and corresponding angles of both the triangles must be congruent for the two triangles to be congruent.
Thus, by the above explanation, it can be concluded that ΔLMP ≅ ΔLOP by SSS.

The probability p(-0.44 ≤ Z ≤ -0.09) is approximately 0.1341.

To find the probability p(-0.44 ≤ Z ≤ -0.09) for the standard normal random variable Z, we can use a standard normal distribution table or a calculator.

Using a standard normal distribution table, we can look up the probabilities corresponding to -0.44 and -0.09 and then subtract the two probabilities to find the desired probability.

From the table,

Z    |     0.00    |     0.01    |     0.02    |     0.03    |     0.04

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

-2.8  |  0.0026  |  0.0025  |  0.0023  |  0.0022  |  0.0021

-2.7  |  0.0035  |  0.0034  |  0.0032  |  0.0031  |  0.0030

-2.6  |  0.0047  |  0.0045  |  0.0043  |  0.0041  |  0.0040

-2.5  |  0.0062  |  0.0060  |  0.0059  |  0.0057  |  0.0055

the probability corresponding to -0.44 is approximately 0.3300, and the probability corresponding to -0.09 is approximately 0.4641.

Therefore, p(-0.44 ≤ Z ≤ -0.09) = 0.4641 - 0.3300 = 0.1341.

So, the probability p(-0.44 ≤ Z ≤ -0.09) is 0.1341.

Integral can be defined as the reverse process of differentiation. Integration is the process of finding the integral of a function. The integral of a function is represented by the symbol ‘∫’.

The anti-derivative or primitive function is a function whose derivative is the given function.

Here, we are given that:

∫X4x2−16dxWe can re-write the given function as:

∫X^4 (x^2 - 16) dx= ∫ X^4 (x + 4) (x - 4) dx

We will now use integration by substitution to solve the above integral:

Let u = x^2 - 16 => du/dx = 2x => dx = du/2x= (1/2) ∫ X^4 (x + 4) (x - 4) dx

Now, substitute the value of u and dx:=(1/2) ∫X^4 (x + 4) (x - 4)

dx= (1/2) ∫(u+16) (u)1/2 du= (1/2) ∫(u3/2 + 16u1/2)

du= (1/2) [2/5 u5/2 + 32/3 u3/2] + C= (1/2) [2/5 (x^2 - 16)5/2 + 32/3 (x^2 - 16)3/2] + C

The quality of water at 28 bar and with an internal energy of 2602.1 kJ/kg cannot be determined as it does not fall within the saturated region.

The quality of water, also known as the vapor fraction or dryness fraction, is a parameter used to determine the ratio of vapor mass to the total mass of a mixture of vapor and liquid water. It is typically defined for saturated or two-phase states where both vapor and liquid coexist. In these cases, the quality can range from 0 to 1, where 0 represents a completely liquid state and 1 represents a completely vapor state.

However, in the given scenario, the water exists at 28 bar and has an internal energy of 2602.1 kJ/kg. This specific condition does not fall within the saturated region of water. The saturated region is where the phase transition from liquid to vapor or vice versa occurs at a specific pressure and temperature. Since the given condition does not fall within this region, the quality value cannot be determined.

Therefore, the answer is that the quality of water at 28 bar and 2602.1 kJ/kg is undetermined as it does not fall within the saturated region.

To evaluate the following definite integral, use integration by substitution. The given definite integral is given by;[tex]$$\int_{1}^{2}((2-t) \sqrt{t})[/tex] d t

Using the u-substitution method, let u be equal to the inner function i.e.,[tex]$$ u = t$$[/tex]

Thus;[tex]$$ du = d t$$[/tex]

Now substitute the values of u and du in the integral equation;[tex]$$ \int_{1}^{2}((2-t) \sqrt{t}) d t = -\int (2-u)\sqrt{u}du$$[/tex]

Distribute the integral across the brackets;[tex]$$ -\int (2-u)\sqrt{u}du = -\int (2\sqrt{u}-u\sqrt{u})du$$[/tex]

Integrate the resulting function;[tex]$$ -\int (2\sqrt{u}-u\sqrt{u})du = -2\frac{2}{3}u^{\frac{3}{2}}-\frac{1}{3}u^{\frac{3}{2}}$$[/tex]

Substitute the value of u into the equation;[tex]$$ -2\frac{2}{3}u^{\frac{3}{2}}-\frac{1}{3}u^{\frac{3}{2}} = \frac{-4}{3}t^{\frac{3}{2}}-\frac{1}{3}t^{\frac{3}{2}}$$[/tex]

Now, substitute the limits of integration in the equation;[tex]$$\int_{1}^{2}((2-t) \sqrt{t}) d t = [\frac{-4}{3}t^{\frac{3}{2}}-\frac{1}{3}t^{\frac{3}{2}}]_{1}^{2}$$[/tex]

Substitute the values of t;[tex]$$[\frac{-4}{3}(2)^{\frac{3}{2}}-\frac{1}{3}(2)^{\frac{3}{2}}]-[\frac{-4}{3}(1)^{\frac{3}{2}}-\frac{1}{3}(1)^{\frac{3}{2}}] = \frac{2}{3} - \frac{-2}{3} = \frac{4}{3}$$[/tex]

Therefore, the main answer is:[tex]$$\int_{1}^{2}((2-t) \sqrt{t}) d t = \frac{4}{3}$$[/tex]

Integration by substitution is an integration method that involves substitution of variables. The aim is to simplify the integral equation so that it can be easily evaluated.
