To differentiate the given function f(x) = 10√[tex](10x^8 + 4x^3)[/tex], we can apply the chain rule. The chain rule states that if we have a composition of functions, such as f(g(x)), then the derivative of f(g(x)) with respect to x is given by f'(g(x)) * g'(x), where f'(x) represents the derivative of the outer function and g'(x) represents the derivative of the inner function.

Let's break down the function f(x) = 10√[tex](10x^8 + 4x^3)[/tex] into its component parts. The outer function is f(u) = 10√u, where u = [tex]10x^8 + 4x^3.[/tex] Taking the derivative of the outer function, we have f'(u) = 10/(2√u) = 5/√u.

The Fourier series representation of the function f(x) = x, -π < x < π can be expressed as a sum of sine functions with coefficients given by (-1)^n / n^2. The function can be represented as f(x) = (π/2) - (4/π)Σ[(-1)^n / n^2]sin(nx), where n takes all positive integer values.

To find the Fourier series representation of f(x), we need to calculate the coefficients ao, an, and bn.

The formula for the Fourier series coefficients is as follows:

ao = (1/π) ∫[-π,π] f(x) dx

an = (1/π) ∫[-π,π] f(x) cos(nx) dx

bn = (1/π) ∫[-π,π] f(x) sin(nx) dx

Let's calculate the coefficients one by one:

1. Calculation of ao:

ao = (1/π) ∫[-π,π] x dx

  = (1/π) [x^2/2]∣[-π,π]

  = (1/π) [(π^2/2) - ((-π)^2/2)]

  = (1/π) [(π^2/2) - (π^2/2)]

  = 0

2. Calculation of an:

an = (1/π) ∫[-π,π] x cos(nx) dx

  = (1/π) [x sin(nx)/n]∣[-π,π] - (1/πn) ∫[-π,π] sin(nx) dx

  = (1/πn) [π sin(nπ) - (-π) sin(-nπ)] - (1/πn^2) [cos(nx)]∣[-π,π]

  = (1/πn) [π sin(nπ) - π sin(nπ)] - (1/πn^2) [cos(nπ) - cos(-nπ)]

  = 0 - (1/πn^2) [(-1)^n - 1]

  = (4/πn^2) [(-1)^n - 1]

3. Calculation of bn:

bn = (1/π) ∫[-π,π] x sin(nx) dx

  = (1/π) [-x cos(nx)/n]∣[-π,π] + (1/πn) ∫[-π,π] cos(nx) dx

  = (1/πn) [-π cos(nπ) - (-π) cos(-nπ)] + (1/πn^2) [sin(nx)]∣[-π,π]

  = (1/πn) [-π cos(nπ) + π cos(nπ)] + (1/πn^2) [0 - 0]

  = 0

Therefore, the Fourier series representation of f(x) = x, -π < x < π is:

f(x) = (π/2) - (4/π)Σ[(-1)^n / n^2]sin(nx)

A. Pyramid has 24 lateral faces.

In this case, we have been told that pyramid has 25 faces. Lateral faces are those third dimensional faces that are neither the base face nor the top face. So to calculate the lateral faces of the pyramid, we need to subtract the given number of faces with total number of base and top faces.

In the case of pyramid, there is no top face so only base face will be considered.

Lateral faces = Total faces - Base faces

Lateral faces = 25 - 1

Lateral faces = 24

Therefore, the pyramis has 24 lateral faces out of 25 faces.

B. Pyramid has 406 edges.

In the question, we know that pyramis has 406 faces. So, the number of edges in a pyramid can be calculated using Euler's formula which is given as F + V = E + 2 where F is number of faces, V is the vertices, and E represents the Edges.

For a pyramid which has 406 faces:

E = F + V - 2

F is given as 406 and pyramid has one base and one vertex, so V = 2:

E = 406 + 2 - 2

E = 406

Therefore, pyramid with 406 faces has 406 edges.

The power series representation for f(x) = 1/2 arctan(x/2) is given by (x/4) - (x^3)/24 + (x^5)/160 - (x^7)/1120 + ..., and the radius of convergence is 1 with the interval of convergence -1 < x < 1.

To find a power series representation for the function f(x) = 1/2 arctan(x/2), we can start by using the power series representation for arctan(x):

arctan(x) = x - (x^3)/3 + (x^5)/5 - (x^7)/7 + ...

Next, we substitute x/2 into the series for arctan(x) and multiply by 1/2:

1/2 arctan(x/2) = (1/2)(x/2) - (1/2)(x^3/2^3)/3 + (1/2)(x^5/2^5)/5 - (1/2)(x^7/2^7)/7 + ...

Simplifying this expression, we have:

1/2 arctan(x/2) = (x/4) - (x^3)/24 + (x^5)/160 - (x^7)/1120 + ...

This is the power series representation for the function f(x) = 1/2 arctan(x/2).

To determine the radius of convergence and interval of convergence for this power series, we can use the ratio test. Applying the ratio test, we have:

lim(n→∞) |a_(n+1)/a_n| = lim(n→∞) |(x^2n+2)/(2^(2n+2)(2n+1)) * (2^(2n)(2n-1))/(x^2n)|

Simplifying and taking the absolute value, we get:

lim(n→∞) |x^2/(4n^2 + 4n)| = |x^2|

Since the limit is |x^2|, the series converges for values of x such that |x^2| < 1. Therefore, the radius of convergence is 1, and the interval of convergence is -1 < x^2 < 1. Taking the square root of the inequality, we have -1 < x < 1.

Adding 8 new comic strips will cause the distribution to be skewed to the positive side.

The correct answer is option B.

To analyze how the skewness of the distribution will be affected by adding 8 new comic strips on the 17th day, let's first calculate the mean and median of the existing data:

Mean = (1 + 1 + 2 + 2 + 2 + 3 + 3 + 3 + 3 + 4 + 4 + 4 + 5 + 5 + 6 + 7) / 16 ≈ 3.25

Median = (3 + 3) / 2 = 3

The existing data has a mean of approximately 3.25 and a median of 3. Now, let's consider the impact of adding 8 new comic strips.

If we add 8 to the existing data, the updated dataset will be:

{1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7, 8}

Since the existing data is sorted in ascending order, adding a higher value (8) will shift the distribution towards the positive side. This means that the values to the right of the median (3) will increase.

Therefore, the correct answer is: B. The distribution will be skewed to the positive side.

In addition, it's important to note that adding a higher value to the dataset will likely affect the mean as well. The new mean will be higher than 3.25 since the added value is greater than the mean. This means that the mean will be pulled towards the higher values, indicating a positive skew.

However, the median will remain the same (3) since it is not influenced by the magnitude of the added value.

The reorder point for bath towels at Chicago's Hard Rock Hotel is approximately 1,494 towels.

To calculate the reorder point, we need to consider the mean demand, lead time, and the desired service level. The mean demand for bath towels is given as 1,200 per day, and the standard deviation is 105 towels per day.

Since the hotel wants to maintain a 98% service level, we need to find the corresponding z-value from the standard normal distribution table. A 98% service level corresponds to a z-value of approximately 2.05.

To calculate the reorder point, we need to consider the lead time. In this case, the lead time is 4 days.

The formula to calculate the reorder point is:

Reorder point = Mean demand during lead time + (Z-value * Standard deviation of demand during lead time)

Calculating the mean demand during lead time:

Mean demand during lead time = Mean demand per day * Lead time

Mean demand during lead time = 1,200 towels/day * 4 days = 4,800 towel

Calculating the standard deviation of demand during lead time:

Standard deviation of demand during lead time = Standard deviation per day * √(Lead time)

Standard deviation of demand during lead time = 105 towels/day * √(4) = 210 towels

Substituting the values into the reorder point formula:

Reorder point = 4,800 towels + (2.05 * 210 towels) = 4,800 towels + 430.5 towels ≈ 1,494 towels

Therefore, the reorder point for bath towels at Chicago's Hard Rock Hotel is approximately 1,494 towels.

b. To find an equation of the line tangent to the graph of `f(x) = 2x² - x - 3` at `(a,  f(a))` where `a = 0`, we use the point-slope form of the equation of a line.

`f(x) = 2x² - x - 3``f'(x) = 4x - 1``f'(0) = 4(0) - 1 = -1`

At `a = 0`, `f(0) = 2(0)² - 0 - 3 = -3`.

Hence, the point of tangency is `(0, -3)` and the slope of the tangent line at that point is `f'(0) = -1`.

Using the point-slope form of the equation of a line, we obtain:`y - y₁ = m(x - x₁)`where `(x₁, y₁) = (0, -3)` and `m = f'(0) = -1`.

y - (-3) = (-1)(x - 0)`

`y + 3 = -x`

`x + y + 3 = 0`

f(x) = xln(x)

f'(x) = ln(x) + 1

To find the critical points, we set f'(x) = 0:

ln(x) + 1 = 0

ln(x) = -1

x = e^(-1) (using the property that ln(x) = y if and only

if x = e^y)

So, the critical point is x = 1/e.

Step 2: Evaluate f(x) at the critical point and endpoints.

f(0) = 0 * ln(0) (Since ln(0) is undefined, we have an endpoint but no function value)

f(1/e) = (1/e) * ln(1/e)

= -1/e * ln(e)

= -1/e

(using the property ln(1/e) = -1)

f(1) = 1 * ln(1)

= 0

f(2) = 2 * ln(2)

Step 3: Compare the function values at the critical point and endpoints to determine the absolute extrema.

From the calculations:

f(0) is not defined.

f(1/e) = -1/e

f(1) = 0

f(2) = 2 * ln(2)

Since f(1/e) is the only function value that is not zero, we can conclude that the absolute minimum occurs at x = 1/e, and

the absolute maximum occurs at x = 2.

Therefore, the absolute extrema of f(x) = xln(x) on the interval [0, 1] are:

Absolute minimum: (-1/e) at x = 1/e

Absolute maximum: 2 at x = 2.

The set V with the defined addition and scalar multiplication operations is a vector space.

To determine if V is a vector space, we need to verify if it satisfies the vector space axioms. Let's check Axioms 7 and 8:

Axiom 7: Scalar multiplication distributes over vector addition.

For any scalar k and vectors u, v in V, we need to check if k(u + v) = ku + kv.

Let's consider:

k(u + v) = k((u1 + v1 + 2, u2 + v2 + 2))

= (k(u1 + v1 + 2), k(u2 + v2 + 2))

= (ku1 + kv1 + 2k, ku2 + kv2 + 2k)

On the other hand:

ku + kv = k(u1, u2) + k(v1, v2)

= (ku1, ku2) + (kv1, kv2)

= (ku1 + kv1, ku2 + kv2)

= (ku1 + kv1 + 2k, ku2 + kv2 + 2k)

Since k(u + v) = ku + kv, Axiom 7 holds.

Axiom 8: Scalar multiplication distributes over scalar addition.

For any scalars k1, k2 and vector u in V, we need to check if (k1 + k2)u = k1u + k2u.

Let's consider:

(k1 + k2)u = (k1 + k2)(u1, u2)

= ((k1 + k2)u1, (k1 + k2)u2)

The representation of y(t) in the compact form shows how the square wave can be decomposed into its sinusoidal components.

To represent a square wave with a 10% duty cycle using the trigonometric method, we can express it as a sum of sinusoidal components.

The square wave has a period of T = 1 and an amplitude of A = 1. The duty cycle is 10%, which means the pulse is "on" for 10% of the period and "off" for the remaining 90% of the period.

Using the trigonometric method, we can write the square wave as:

y(t) = (4A/π) * [sin(2πft) + (1/3)sin(6πft) + (1/5)sin(10πft) + ...]

where f = 1/T is the fundamental frequency.

In this case, f = 1/1 = 1, so the square wave can be represented as:

y(t) = (4/π) * [sin(2πt) + (1/3)sin(6πt) + (1/5)sin(10πt) + ...]

The compact form of the square wave with a 10% duty cycle using the trigonometric method is given by the summation of the harmonics of the fundamental frequency, with appropriate coefficients.

The derivative \(y'\) for the function \(y = \cos^k(kx)\) is: \[y' = -k^2\cos^{k-1}(kx)\sin(kx)\]

To find \(y'\) for the function \(y = \frac{x - x^k}{x + x^k}\), where \(k > 0\) is an integer constant, we can apply the quotient rule of differentiation. The quotient rule states that if we have a function \(y = \frac{u}{v}\), then its derivative is given by:

\[y' = \frac{u'v - uv'}{v^2}\]

In our case, let's define \(u = x - x^k\) and \(v = x + x^k\). We need to find the derivatives \(u'\) and \(v'\) and substitute them into the quotient rule formula.

First, let's find \(u'\):

\[u' = \frac{d}{dx}(x - x^k)\]

The derivative of \(x\) with respect to \(x\) is 1, and the derivative of \(x^k\) with respect to \(x\) can be found using the power rule:

\[u' = 1 - kx^{k-1}\]

Next, let's find \(v'\):

\[v' = \frac{d}{dx}(x + x^k)\]

Again, the derivative of \(x\) with respect to \(x\) is 1, and the derivative of \(x^k\) with respect to \(x\) is \(kx^{k-1}\):

\[v' = 1 + kx^{k-1}\]

Now we can substitute \(u'\) and \(v'\) into the quotient rule formula:

\[y' = \frac{(1 - kx^{k-1})(x + x^k) - (x - x^k)(1 + kx^{k-1})}{(x + x^k)^2}\]

Expanding and simplifying the expression:

\[y' = \frac{x + x^k - kx^{k} - kx^{k+1} - x + x^k + kx^{k} - kx^{k+1}}{(x + x^k)^2}\]

Combining like terms:

\[y' = \frac{2x^k - 2kx^{k+1}}{(x + x^k)^2}\]

Therefore, the derivative \(y'\) for the function \(y = \frac{x - x^k}{x + x^k}\) is:

\[y' = \frac{2x^k - 2kx^{k+1}}{(x + x^k)^2}\]

Now let's find \(y'\) for the function \(y = \cos^k(kx)\), where \(k > 0\) is an integer constant.

To find the derivative of \(y\), we can use the chain rule. The chain rule states that if we have a composition of functions \(y = f(g(x))\), then its derivative is given by:

\[y' = f'(g(x)) \cdot g'(x)\]

In our case, let's define \(f(u) = u^k\) and \(g(x) = \cos(kx)\). The derivative \(y'\) can be found by applying the chain rule to these functions.

First, let's find \(f'(u)\):

\[f'(u) = \frac{d}{du}(u^k)\]

Using the power rule, the derivative of \(u^k\) with respect to \(u\) is:

\[f'(u) = ku^{k-1}\]

Next, let's find \(g'(x)\):

\[g'(x) = \frac{d}{

dx}(\cos(kx))\]

The derivative of \(\cos(kx)\) with respect to \(x\) can be found using the chain rule and the derivative of \(\cos(x)\):

\[g'(x) = -k\sin(kx)\]

Now we can substitute \(f'(u)\) and \(g'(x)\) into the chain rule formula:

\[y' = f'(g(x)) \cdot g'(x)\]

\[y' = ku^{k-1} \cdot (-k\sin(kx))\]

Since \(u = \cos(kx)\), we can rewrite \(ku^{k-1}\) as \(k\cos^{k-1}(kx)\):

\[y' = k\cos^{k-1}(kx) \cdot (-k\sin(kx))\]

Combining the terms:

\[y' = -k^2\cos^{k-1}(kx)\sin(kx)\]

b. The distance between the library and high school to the nearest tenth of a kilometre is 1.2 km

c.  The total distance walked by Chaeli is 5 km.

b) The distance between the library and the high school is found by using the Cosine rule.

Cosine rule:

In any triangle ABC, cos A=  b² + c² - a²/ 2bcWhere a, b, and c are the sides of the triangle and A, B, and C are the angles of the triangle. Here A is 125°, b is 1.7 km and c is 3.1 km.

By using the above formula:cos 125° = (3.1)² + (1.7)² - 2 × 3.1 × 1.7 cos 125°= 10.3  cos 125°= - 0.597

Cosine function value is negative in the 2nd quadrant of a unit circle. This means the angle of 125° lies in the 2nd quadrant. Hence we need to subtract this angle from 180° to get the acute angle between the lines.55° = 180° - 125°Again using the cosine rule,cos 55°= (b)² + (1.7)² - 2(b)(1.7)cos 55° = 3.13 - 3.4b + b²0 = b² - 3.4b + 3.13

Using the quadratic formula, the solutions for b can be found as

b = 1.153 km or b = 2.247 km

Since b represents the distance between the library and the high school and should be shorter than both given distances, the distance between the library and high school to the nearest tenth of a kilometre is 1.2 km.

c) Chaeli walks from his house to the high school and then walks to the library and finally returns home.From the cosine rule in part b, we know that distance between the library and high school is 1.2 km.

Therefore, Chaeli walks 3.1 km + 1.2 km + 1.7 km = 5 km in total to the nearest tenth of a kilometre. So, the total distance walked by Chaeli is 5 km.

The sketch of the region is given below: Sketch of the region

Then, we need to rotate this region around the y-axis to obtain a solid. When we do so, we get a solid as shown below:

Solid obtained by rotating the region

We need to find the volume of this solid. To do so, we can use the washer method.

According to the washer method, the volume of the solid obtained by rotating a region bounded by

y = f(x), y = g(x), x = a, and x = b about the y-axis is given by:

[tex]$$\begin{aligned}\pi \int_{a}^{b} (R^2 - r^2) dx\end{aligned}$$[/tex]

where R is the outer radius (distance from the y-axis to the outer edge of the solid), and r is the inner radius (distance from the y-axis to the inner edge of the solid).

Here, R = 10 (distance from the y-axis to the top of the solid) and r = 3x² (distance from the y-axis to the bottom of the solid).Since we are rotating the region about the y-axis, the limits of integration are from y = 0 to y = 10 (the height of the solid).

Therefore, we need to express x in terms of y and then integrate.

To do so, we can solve y = 3x²  for x:

[tex]$$\begin{aligned}y = 3x^2\\x^2 = \frac{y}{3}\\x = \sqrt{\frac{y}{3}}\end{aligned}$$[/tex]

Therefore, the volume of the solid is:

[tex]$$\begin{aligned}\pi \int_{0}^{10} (10^2 - (3x^2)^2) dy &= \pi \int_{0}^{10} (10^2 - 9y^2/4) dy\\&= \pi \left[10^2y - 3y^3/4\right]_{0}^{10}\\&= \pi (1000 - 750)\\&= \boxed{250 \pi}\end{aligned}$$[/tex]

Therefore, the volume of the solid obtained by rotating the region bounded by y = 3x² , y = 10, and x = 0 about the y-axis is 250π cubic units.

We can see that the region is a shape with a height of 10 and the bottom of the shape is bounded by y = 3x². We may now calculate the volume of the solid using the formula for the volume of a solid obtained by rotating a region bounded by curves about the y-axis as follows:V = ∫aᵇA(y) dywhere A(y) is the area of a cross-section and a and b are the bounds of integration.

In this instance, the bounds of integration are 0 and 10, and A(y) is the area of a cross-section perpendicular to the y-axis. It will be a circular area with radius x and thickness dy, rotating around the y-axis.  The formula to be used is A(y) = π x².

By using the equation x = √(y/3), we can write A(y) in terms of y as A(y) = π (y/3). Hence,V = π ∫0¹⁰ [(y/3)]² dy = π ∫0¹⁰ [(y²)/9] dyV = π [(y³)/27] ₀¹⁰ = π [(10³)/27] = (1000π)/27

Therefore, the volume of the solid obtained by rotating the region bounded by y = 3x², y = 10, and x = 0 about the y-axis is (1000π)/27 cubic units.
