Answers
The first three terms of x[n] using the power series expansion are x[0] = 73, x[1] = 2, and x[2] = 13.
We can select the first three terms of x[n] using the power series development by expressing the given articulation X(z) as a polynomial in z. We should modify the articulation as follows to obtain the power series development: By comparing the given expression to the power series form, the coefficients can be identified: X(z) equals 2z3, 13z2, 7z, 73, 722/z, 2/z, and 1: a0 rises to 73, a1 approaches 2, a2 approaches 13, and a3 approaches 7. X(z) = a0, a1z, a2z2, a3*z3, and... Consequently, the following are the first three terms of x[n]:
The initial three terms of x[n] are provided by the power series development: x[0] = a0; x[1] = a1; x[2] = a2; x[0] = a0; The values of x[0] and x[1] are 73, 2, and 13.

Answers
the linear approximation at z = 0 to sin(42) is A + Bz, where A = sin(42) and B is the coefficient of z, which is cos(42).
The linear approximation of a function f(x) at a point x = a is given by the equation f(x) ≈ f(a) + f'(a)(x - a). In this case, we want to approximate sin(42) at z = 0.
The derivative of the sine function is cos(x), so the derivative of sin(42) with respect to z is cos(42). Evaluating the derivative at z = 0, we have cos(42).
To find A in the linear approximation A + Bz, we substitute z = 0 into the original function sin(42) and obtain A = sin(42).
Therefore, the linear approximation at z = 0 to sin(42) is A + Bz, where A = sin(42) and B is the coefficient of z, which is cos(42).

P(M> 19.4) =
Previous question
Answers
(a) The probability that a single randomly selected value is greater than 19.4. P(X> 19.4) = 0.6965.
(b) The probability that a sample of size n = 20 is randomly selected with a mean greater than 19.4. P(M> 19.4) = 0.9883.
To solve these probability questions, we can utilize the properties of the standard normal distribution since we know the mean and standard deviation of the population.
(a) Find the probability that a single randomly selected value is greater than 19.4.
To calculate this probability, we need to standardize the value 19.4 using the formula: z = (x - μ) / σ, where x is the value, μ is the mean, and σ is the standard deviation.
z = (19.4 - 42.3) / 44.6 = -22.9 / 44.6 ≈ -0.51498
Using the standard normal distribution table or a calculator, we can find the corresponding probability for z > -0.51498, which is approximately 0.6965.
Therefore, P(X > 19.4) ≈ 0.6965.
(b) Find the probability that a sample of size n = 20 is randomly selected with a mean greater than 19.4.
For this question, we need to consider the sampling distribution of the sample mean. The mean of the sampling distribution is equal to the population mean (μ = 42.3), and the standard deviation of the sampling distribution, also known as the standard error, is equal to σ / √n, where σ is the population standard deviation and n is the sample size.
Standard error = 44.6 / √20 ≈ 9.9766
To find the probability that the sample mean is greater than 19.4, we need to standardize the sample mean using the formula: z = (x - μ) / (σ / √n), where x is the value (19.4 in this case), μ is the mean, σ is the standard deviation, and n is the sample size.
z = (19.4 - 42.3) / (44.6 / √20) ≈ -22.9 / 9.9766 ≈ -2.2972
Using the standard normal distribution table or a calculator, we can find the corresponding probability for z > -2.2972, which is approximately 0.9883.
Therefore, P(M > 19.4) ≈ 0.9883.

b) F(s)= s/s²+4s+5
c) F(s)=e^-3s s/(s-2)^2 +81
Answers
a) The solution to the given problem isL(F) = f(t) = 0 + (-(10 + 7C)/6)[tex]e^{-2t}[/tex]) + C[tex]e^{-3t}[/tex]+ D[tex]e^{-3t}[/tex]
b) The solution to the given problem isL(F) = [tex]e^{-2t}[/tex] [sin t + cos t](c)
c) The solution to the given problem is L(F) = 1/9 [[tex]e^{2t}[/tex] sin 9t - 3[tex]e^{2t}[/tex]) cos 9t]
(a)The inverse Laplace transform of F(s) = 10/s(s + 2)(s + 3)² can be found as follows:
L(F) = L{10/[s(s + 2)(s + 3)²]}
= 10 ∫∞₀[tex]e^{-st}[/tex]) /[s(s + 2)(s + 3)²] dt
L{F} = L⁻¹{10/[s(s + 2)(s + 3)²]}
By using partial fractions, we can simplify the equation and get it in a form that can be integrated easily.
L(F) = 10 ∫∞₀ {1/s - 2/(s + 2) + 3/(s + 3) - 2/(s + 3)² + 1/(s + 2)(s + 3)} [tex]e^{-st}[/tex]dt
L{F} = L⁻¹{1/s} - 2L⁻¹{1/(s + 2)} + 3L⁻¹{1/(s + 3)} - 2L⁻¹{d/ds[1/(s + 3)]} + L⁻¹{1/(s + 2)}
As the inverse Laplace transform of L{F} is given by L(F)
= L⁻¹{1/s} - 2L⁻¹{1/(s + 2)} + 3L⁻¹{1/(s + 3)} - 2L⁻¹{d/ds[1/(s + 3)]} + L⁻¹{1/(s + 2)}
Thus, the solution to the given problem isL(F) = f(t) = 0 + (-(10 + 7C)/6)[tex]e^{-2t}[/tex]) + C[tex]e^{-3t}[/tex]+ D[tex]e^{-3t}[/tex]
(b)
The inverse Laplace transform of F(s) = s/[s² + 4s + 5] can be found as follows:
L(F) = L{s/[s² + 4s + 5]}
= ∫∞₀ s e^(–st) / (s² + 4s + 5) dt
L{F} = L⁻¹{s/[s² + 4s + 5]}
By using partial fractions, we can simplify the equation and get it in a form that can be integrated easily. L(F) = ∫∞₀ [s/(s² + 4s + 5)] [tex]e^{-st}[/tex]) dt
L{F} = L⁻¹{s/(s² + 4s + 5)}
The solution to the given problem isL(F) = [tex]e^{-2t}[/tex] [sin t + cos t](c)
c) The inverse Laplace transform of F(s) = ([tex]e^{-3s}[/tex]) s/[(s - 2)² + 81] can be found as follows:
L(F) = L{([tex]e^{-3s}[/tex]) s/[(s - 2)² + 81]}= ∫∞₀ ([tex]e^{-st}[/tex]) s/[(s - 2)² + 81] dt
L{F} = L⁻¹{([tex]e^{-3s}[/tex])) s/[(s - 2)² + 81]}
So, The solution to the given problem is L(F) = 1/9 [([tex]e^{2t}[/tex]) sin 9t - 3([tex]e^{2t}[/tex]) cos 9t]

How would I find the arc of WTV
Answers
To find the arc of circle WTV, you need the arc length or central angle. Use formulas: Arc Length = (Arc Angle / 360) × (2πr) or Arc Length = (Central Angle / 360) × (2πr).
To find the arc of a circle, WTV, you would need to know either the length of the arc or the measure of the central angle subtended by the arc. If you have the length of the arc, you can use the formula:
Arc Length = (Arc Angle / 360 degrees) × (2πr),
where r is the radius of the circle. Rearranging the formula, you can solve for the Arc Angle:
Arc Angle = (Arc Length / (2πr)) × 360 degrees.
If you know the measure of the central angle, you can calculate the arc length using a similar formula:
Arc Length = (Central Angle / 360 degrees) × (2πr).
To find the radius, you would need additional information such as the diameter or circumference of the circle. Once you have the radius, you can substitute the values into the appropriate formula to find either the arc length or the central angle of the circle.

Danny is in a 90 m high watchtower. Lily and Bryan are out searching for clues in regards to a route taken by an escaped prisoner. Lily radios to Danny that she has found some evidence and estimates that she is 350 m from the base of the watchtower. Danny radios this information to Bryan, who estimates that from his location, the angle of elevation to the top of the watchtower is 20°. Danny estimates that the angle from Bryan to the base of the watchtower to Lily is 85°.
a) To the nearest meter, how far is Bryan from the base of the watchtower?
b) To the nearest meter, how apart are Bryan and Lily?
Answers
a) Bryan is 1,168 meters away from the base of the watchtower
b) The nearest meter, Bryan and Lily are 315
a) To the nearest meter, Bryan is 1,168 meters away from the base of the watchtower.
Let AB be the watchtower. From B, the angle of elevation to the top of the tower is 20°.
We have to find BC.
BC/AB = tan 20°
BC = AB tan 20°
BC = 90 tan 20°
BC = 32.3
Therefore, BC = 32 meters
Now we have to find AC. AC is the distance between the foot of the watchtower and Bryan's position.
To do that, let BD = h be the height of the tower and AD = x be the distance between A and D.
From the information given, we know that tan 85° = h/x.
Rearranging the formula, x = h/tan 85°
x = 90/tan 85°
x = 418.55 meters
Therefore, AC = x + BC
AC = 418.55 + 32.3
AC = 450.85 meters
So, to the nearest meter, Bryan is 1,168 meters away from the base of the watchtower.
b) To the nearest meter, Bryan and Lily are 315 meters apart.
Let E be the position of Lily and AD be the distance from the foot of the watchtower to the position of Bryan. We have already found that AD = 418.55 meters.
Bryan and Lily are along the same horizontal line.
So, BE is the distance between them. We have to find BE.
From triangle AEB, tan 20° = h/AE.
Rearranging the formula, AE = h/tan 20°
AE = 90/tan 20°
AE = 267.9 meters
From triangle DEC, tan 85° = h/DE.
Rearranging the formula, DE = h/tan 85°
DE = 90/tan 85°
DE = 3,442.97 meters
Therefore, EC = DE - DC = 3,442.97 - 350 = 3,092.97 meters
Now, BE = AC - EC
BE = 450.85 - 3,092.97
BE = -2,642.12 meters (negative value means Bryan is to the left of Lily)So, to the nearest meter,
Bryan and Lily are 315 meters apart. Answer: (a) 1168m and (b) 315m

How many zeros appear at the end of 115!? Do not compute 115!.
Your argument must come from prime factorizations to receive
credit.
Answers
there will be 27 zeros at the end of 115!.
To determine the number of zeros at the end of 115!, we need to consider the prime factorization of the number and examine how many factors of 5 are present.
A zero at the end of a factorial occurs when there is a factor of 10 present, which is equivalent to having both factors of 2 and 5. Since the number of factors of 2 is usually abundant, the crucial factor is the number of factors of 5.
In the prime factorization of 115!, the factors of 5 arise from the multiples of 5 (5, 10, 15, 20, ...) as well as higher powers of 5 (25, 50, 75, ...). We need to determine how many multiples of 5, multiples of 25, multiples of 125, and so on are present.
1. Multiples of 5: The number of multiples of 5 in 115! is given by ⌊115/5⌋ = 23.
2. Multiples of 25: The number of multiples of 25 in 115! is given by ⌊115/25⌋ = 4.
3. Multiples of 125: The number of multiples of 125 in 115! is given by ⌊115/125⌋ = 0 since there are no numbers in the range 1 to 115 that are multiples of 125.
Adding up these counts, we have 23 + 4 = 27 factors of 5.
Therefore, there will be 27 zeros at the end of 115!.

Answers
The sum of the mean and the median of the given dataset, which consists of the scores 7, 4, 9, 6, 10, 9, 5, and 4, is 13.25.
To find the sum of the mean and the median, we first need to calculate the mean and median of the given dataset.
The dataset is: 7, 4, 9, 6, 10, 9, 5, 4
To find the mean, we sum up all the numbers in the dataset and divide by the total number of data points:
Mean = (7 + 4 + 9 + 6 + 10 + 9 + 5 + 4) / 8 = 54 / 8 = 6.75
To find the median, we arrange the numbers in ascending order:
4, 4, 5, 6, 7, 9, 9, 10
Since we have 8 data points, the median will be the average of the two middle numbers:
Median = (6 + 7) / 2 = 6.5
Now we can find the sum of the mean and the median:
Sum of mean and median = 6.75 + 6.5 = 13.25
Therefore, the sum of the mean and the median of the given dataset is 13.25.
