The function S(x) = 4(x - 2x) for x > 0 is increasing on the open interval (0, +∞) and does not have any relative maxima or minima.

To determine the intervals on which S(x) is increasing or decreasing, we need to examine the derivative of S(x). Taking the derivative of S(x) with respect to x, we get:

S'(x) = 4(1 - 2) = -4

Since the derivative is a constant (-4) and negative, it means that S(x) is decreasing for all values of x. Therefore, S(x) does not have any relative maxima or minima.

In terms of intervals, the function S(x) is decreasing on the entire domain of x > 0, which means it is decreasing on the open interval (0, +∞). Since it is always decreasing and does not have any turning points, there are no relative maxima or minima to be found.

The hollow sphere must have an angular speed of ω1 in order to have the same kinetic energy (k1) as the uniform sphere.

The kinetic energy (K) of a rotating object can be calculated using the formula K = (1/2) I ω², where I is the moment of inertia and ω is the angular speed. For a hollow sphere, the moment of inertia (I) is given by I = (2/3) m R², where m is the mass and R is the radius.

If the kinetic energy of the hollow sphere is k1, we can set up the equation (1/2)(2/3) m R² ω1² = k1. Simplifying this equation, we get (1/3) m R² ω1² = k1.

Now, let's consider a uniform sphere with the same mass and radius as the hollow sphere. The moment of inertia for a uniform sphere is given by I = (2/5) m R². Since the kinetic energy (k1) is the same for both the hollow and uniform spheres, we can set up another equation: (1/2)(2/5) m R² ω2² = k1. Simplifying this equation, we get (1/5) m R² ω2² = k1.

Since k1 is the same in both equations, we can equate the right sides: (1/3) m R² ω1² = (1/5) m R² ω2². Canceling out the mass and radius terms, we have (1/3) ω1² = (1/5) ω2².

Therefore, in order for the hollow sphere to have the same kinetic energy as the uniform sphere, it must have an angular speed of ω1, which is related to the angular speed of the uniform sphere (ω2) by the equation ω1² = (3/5) ω2².

The distance is:

√(x - 9)² + (y - 3)² = √(x - 7)² + (y + 1)² = √(x + 1)² + (y - 3)²

√(x - 9)² + (y - 3)² = √(x + 1)² + (y - 3)²

(x - 9)² + (y - 3)² = (x + 1)² + (y - 3)²

(x - 9)² =  (x + 1)²

x² - 18x + 81 = x² + 2x + 1

Therefore, the probability that more than 50% of the people in the sample are married is approximately 0.115 (rounded to three decimal places).

To solve this problem, we can use the normal approximation to the binomial distribution since the sample size is large (n = 1000) and the proportion of married persons (p) is not too close to 0 or 1.

The mean of the sample proportion can be calculated as:

μ = p = 0.482

The standard deviation of the sample proportion can be calculated as:

σ = sqrt((p * (1 - p)) / n) = sqrt((0.482 * (1 - 0.482)) / 1000) ≈ 0.015

To find the probability that more than 50% of the people in the sample are married, we need to calculate the z-score and find the area under the normal curve to the right of this z-score.

The z-score can be calculated as:

z = (x - μ) / σ = (0.5 - 0.482) / 0.015 ≈ 1.200

When the company has 5 workers and the average salary per worker is $35000, then increasing the number of workers by one will increase the average payroll by $45000.

a) We need to find dA/dw when w = 5 and S(5) = 35000 and S'(5) = 2000.

We know that A(w) = wS(w).

By product rule, dA/dw = wdS/dw + S.

We need to find dA/dw when w = 5.So, dA/dw = 5dS/dw + S  ...............................(1)

Given, S(5) = 35000.

So, we know the value of S at w = 5.

Given, S'(5) = 2000.

So, dS/dw at w = 5 is 2000.

Now, putting w = 5, dS/dw = 2000 and S = 35000 in equation (1), we get

dA/dw = 5dS/dw + S= 5 × 2000 + 35000= 45000

Therefore, the value of dA/dw at w = 5 when S(5) = 35000 and S'(5) = 2000 is 45000.b) In part (a), we found that dA/dw = 45000 when w = 5. Therefore, when the company has 5 workers and the average salary per worker is $35000, then increasing the number of workers by one will increase the average payroll by $45000.

The Fourier series and the Fourier cosine series of f(x) = -x on the given intervals are identically zero.

To determine the Fourier series of the function f(x) = -x on the interval [-1, 1], we can use the general formulas for the Fourier coefficients.

The Fourier series representation of f(x) on the interval [-1, 1] is given by:

F(x) = a₀/2 + Σ(aₙcos(nπx/L) + bₙsin(nπx/L)), where L is the period (2 in this case).

To find the Fourier coefficients, we need to compute the values of a₀, aₙ, and bₙ.

A₀ = (1/L) ∫[−L,L] f(x) dx = (1/2) ∫[−1,1] -x dx = 0

Aₙ = (1/L) ∫[−L,L] f(x) cos(nπx/L) dx = (1/2) ∫[−1,1] -x cos(nπx) dx = 0 (due to symmetry)

Bₙ = (1/L) ∫[−L,L] f(x) sin(nπx/L) dx = (1/2) ∫[−1,1] -x sin(nπx) dx

Using integration by parts, we find:

Bₙ = (1/2) [x (1/nπ) cos(nπx) + (1/nπ) ∫[−1,1] cos(nπx) dx]

    = -(1/2) (1/(nπ)) [x sin(nπx) - ∫[−1,1] sin(nπx) dx]

    = (1/2nπ²) [cos(nπx)]├[−1,1]

    = (1/2nπ²) [cos(nπ) – cos(-nπ)]

    = 0 (since cos(nπ) = cos(-nπ))

Therefore, all the Fourier coefficients a₀, aₙ, and bₙ are zero. This means that the Fourier series of f(x) = -x on the interval [-1, 1] is identically zero.

For the Fourier cosine series on [0, 1], we only consider the cosine terms:

F(x) = a₀/2 + Σ(aₙcos(nπx/L))

Since all the Fourier coefficients are zero, the Fourier cosine series of f(x) on [0, 1] is also zero.

The correct relationship between a and b that must be true in the given system of inequalities is ∣a∣ > ∣b∣. The answer is C

What is a system of inequalities?

A system of inequalities refers to a set of multiple inequalities that are considered simultaneously. The solution to the system consists of all the values that satisfy each inequality in the system. It represents a region in the coordinate plane where the shaded area encompasses all the valid solutions for the given set of inequalities.

Given the inequalities y < -x + a and y > x + b, we know that the point (0,0) satisfies both of these inequalities. Plugging in x = 0 and y = 0 into the inequalities, we get:

0 < a   (from y < -x + a)

0 > b   (from y > x + b)

From these equations, we can conclude that a must be greater than 0 (since 0 < a) and b must be less than 0 (since 0 > b). To compare their magnitudes, we take the absolute values:

∣a∣ > 0   (since a > 0)

∣b∣ < 0   (since b < 0)

Since the magnitude of a (∣a∣) is greater than the magnitude of b (∣b∣), the correct relationship is ∣a∣ > ∣b∣, which is option C.

The class boundaries for the given class are 14.2-18.6. The midpoint of the given class is 16.4. The width of the given class is 3.4 units.

The class boundaries, midpoint, and width for the class 14.7-18.1 are as follows:

Class Boundaries

For the given class, we must first identify the upper and lower boundaries.

The lower boundary is calculated by subtracting 0.5 from the lower class limit, and the upper boundary is calculated by adding 0.5 to the upper class limit.

Lower boundary = Lower class limit - 0.5 = 14.7 - 0.5 = 14.2

Upper boundary = Upper class limit + 0.5 = 18.1 + 0.5 = 18.6

Thus, the class boundaries for the given class are 14.2-18.6.

MidpointTo find the midpoint of a class, we add the upper and lower class limits and divide by 2.

Therefore, the midpoint of the class 14.7-18.1 can be calculated as follows:

Midpoint = (Lower class limit + Upper class limit) / 2= (14.7 + 18.1) / 2= 16.4

Therefore, the midpoint of the given class is 16.4.

Width

The width of the class is obtained by subtracting the lower class limit from the upper class limit.

Hence, the width of the given class is:

Width = Upper class limit - Lower class limit= 18.1 - 14.7= 3.4

In the given differential equation, if F(x, y) = C is a solution, the task is to determine the value of F(0, 2). The options provided are a) 4, b) 0, c) 8, and d) 1.

To find the value of F(0, 2), we substitute the values x = 0 and y = 2 into the equation F(x, y) = C, which is a solution of the given differential equation.

Plugging in x = 0 and y = 2 into the differential equation, we have:

[2(2cos0 + 1) + 4(2)cos(z)]dy + [2(2 - 0) + 2]dx = 0.

Simplifying, we get:

[2(3) + 8cos(z)]dy + 4dx = 0.

Integrating both sides of the equation, we have:

2(3y + 8sin(z)) + 4x = K,

where K is a constant of integration.

Since F(x, y) = C, we have K = C.

Substituting x = 0 and y = 2 into the equation, we get:

2(3(2) + 8sin(z)) + 4(0) = C.

Simplifying, we have:

12 + 16sin(z) = C.

The Taylor series is the power series of a function f(x) that is represented as the sum of its derivative values evaluated at a single point, multiplied by the corresponding powers of x − a. If you need to find the Taylor series for f(x) = x - 3 centered at c = 1, then the answer is given below.Taylor series for f(x) = x - 3 centered at c = 1:It can be obtained by the following steps:First, we need to find the n-th derivative of the function f(x) using the formula:dn/dxⁿ (f(x)) = dⁿ-¹/dxⁿ-¹ (df(x)/dx)Now, let us differentiate the given function f(x) = x - 3:df(x)/dx = 1dn/dx (f(x)) = 0dn/dx² (f(x)) = 0dn/dx³ (f(x)) = 0dn/dx⁴ (f(x)) = 0...We can see that all higher derivatives are zero for the given function f(x) = x - 3. Therefore, the nth term of the Taylor series for the given function is: fⁿ(c) (x - c)ⁿ/n!The Taylor series for f(x) = x - 3 centered at c = 1 can be represented as follows:f(x) = f(1) + f'(1)(x - 1) + f''(1)(x - 1)²/2! + f'''(1)(x - 1)³/3! + ...= -2 + (x - 1)

Therefore, (0.101101101...)2 can be expressed as 1410 / 99 for the given binomial expansion.

The solution to the given question is as follows(a) To obtain the binomial expansion of (1 - x)-1 up to and including the term in x2, we use the following formula:

(1 + x)n = 1 + nx + n(n - 1) / 2! x2 + n(n - 1)(n - 2) / 3! x3 + ...The formula applies when n is a positive integer. When n is negative or fractional, we obtain a more general formula that applies to any value of n, such as(1 + x)n = 1 / (1 - x) n = 1 - nx + (n(n + 1) / 2!) x2 - (n(n + 1)(n + 2) / 3!) x3 + ...where the expansion is valid when |x| < 1.Substituting -x for x in the second formula gives us(1 - x)-1 = 1 + x + x2 + x3 + ...

The binomial expansion of (1 - x)-1 up to and including the term in x2 is therefore:1 + x + x2.To solve for (1 – x)(2 – 3x) in the form A + - X B 2-3x, we expand the expression (1 - x)(2 - 3x) = 2 - 5x + 3x2.

The required expression can be expressed as follows:A - BX 2-3x = A + BX (2 - 3x)Setting (2 - 3x) equal to 1, we get B = -1.Substituting 2 for x in the original equation gives us 3. Hence A - B(3) = 3, which implies A = 0.Thus, (1 – x)(2 – 3x) can be expressed in the form 0 + 1X(2 - 3x).

Therefore, (1 – x)(2 – 3x) in the form A + - X B 2-3x is equal to X - 6.(b) (i) To express 1 / 3 in terms of powers of 2, we proceed as follows:1 / 3 = 2k(0.a1a2a3...)2-1 = 2k a1. a2a3...where 0.a1a2a3... represents the binary expansion of 1 / 3, and k is an integer that can be determined as follows:2k > 1 / 3 > 2k+1

Dividing all sides of the above inequality by 2k+1, we get1 / 2 < (1 / 3) / 2k+1 < 1 / 4This implies that k = 1, and the binary expansion of 1 / 3 is therefore 0.01010101....Therefore, 1 / 3 can be expressed as a sum of a geometric series as follows:1 / 3 = (0.01010101...)2= (0.01)2 + (0.0001)2 + (0.000001)2 + ...= (1 / 4) + (1 / 16) + (1 / 256) + ...= 1 / 3(ii)

To convert (0.101101101...)2 to a rational number, we use the fact that any repeating binary expansion can be expressed as a rational number of the form p / q, where p is an integer and q is a positive integer with no factor of 2 or 5. Let x = (0.101101101...)2. Multiplying both sides by 8 gives8x = (101.101101101...)2. Subtracting x from 8x gives7x = (101.101)2. Multiplying both sides by 111 gives777x = 111(101.101)2= 11101.1101 - 111.01

Thus, x = (11101.1101 - 111.01) / 777= (10950.8 - 7) / 777= 10943.8 / 777= 1410 / 99 Therefore, (0.101101101...)2 can be expressed as 1410 / 99.

The range of the piecewise function is [4, ∞), the correct option is the first one.

Here we have function g(x), which is a piecewise function, so it behaves differently in different parts of its domain.

Now, we can see that when x < 2, the function is quadratic with positive leading coefficient, so it will tend to infinity as x → -∞

Then we have g(x) = 2x when x ≥ 2, this line also tends to infinity.

Now let's find the minimum of the range.

When x = 0, we will have:

g(0) = 0² + 5 = 5

That is the minimum (because if x ≠ 0 we will have a larger value)

And when x = 2 we use the other part:

g(2) = 2*2 = 4

That is the minimum value of the line.

Then the range is [4, ∞)

The correct option is the first one.

Answer:

Step-by-step explanation:

Functions are not differentiable at sharp corners.  For an absolute value function, a sharp corner happens at the vertex.

f(x) = a |x -h| + k  where (h, k) is the vertex

For your function:

g(x) = |x-6| + 2     the vertex is at (6, 2) so the function is not differentiable at (6,2)

b) There are 2 ways to solve this.  You can break down the derivative or know the slope.  We will take a look at slope.  The derivative is the slope of the function at that point. We know that there is no stretch to your g(x) function so the slope left of (6,2) is -1 and the slope right of (6,2) is +1  

Knowing this your g' will all be -1 or +1

g'(0) = -1

g'(1) = -1

g'(7) = 1

g'(14) = 1

Given data: A bus that holds a maximum of 94 people Profit function: P(x) = x(47 - 0.5x) - 94where x represents the number of people taken on the toura. To find out how many people the guide should take on the tour to maximize the profit, we need to find the derivative of the profit function and equate it to zero.

P(x) = x(47 - 0.5x) - 94Let's differentiate P(x) with respect to x using the product rule. P(x) = x(47 - 0.5x) - 94P'(x) = (47 - x) - 0.5x = 47 - 1.5xNow, we equate P'(x) = 0 to find the critical point.47 - 1.5x = 0- 1.5x = -47x = 47/1.5x = 31.33Since we cannot have 0.33 of a person, the maximum number of people the guide should take on the tour is 31 people to maximize the profit.b. Suppose the bus holds a maximum of 41 people. To find the number of people who should go on the tour to maximize the profit, we repeat the above process. We use 41 instead of 94 as the maximum capacity of the bus.P(x) = x(47 - 0.5x) - 41Let's differentiate P(x) with respect to x using the product rule. P(x) = x(47 - 0.5x) - 41P'(x) = (47 - x) - 0.5x = 47 - 1.5xNow, we equate P'(x) = 0 to find the critical point.47 - 1.5x = 0- 1.5x = -47x = 47/1.5x = 31.33Since we cannot have 0.33 of a person, the maximum number of people the guide should take on the tour is 31 people to maximize the profit.c. To find the derivative of the given function P(x) = x(47 - 0.5x) - 94, let's use the product rule. P(x) = x(47 - 0.5x) - 94P'(x) = (47 - x) - 0.5x = 47 - 1.5xThus, the derivative of the function P(x) = x(47 - 0.5x) - 94 is P'(x) = 47 - 1.5x.

To solve the given differential equation using Laplace transforms, we apply the Laplace transform to both sides of the equation. By transforming the differential equation into an algebraic equation in the Laplace domain and using the initial conditions, we find the Laplace transform of the unknown function. Then, by taking the inverse Laplace transform, we obtain the solution in the time domain.

Let's denote the unknown function as Y(s) and its derivative as Y'(s). Applying the Laplace transform to the given differential equation, we have sY(s) - y(0) = 3s/(s^2 + 9) - 11/(s^2 + 9). Using the initial conditions y(0) = 0 and y'(0) = 6, we substitute these values into the Laplace transformed equation. After rearranging the equation, we solve for Y(s) in terms of s. Next, we take the inverse Laplace transform of Y(s) to obtain the solution y(t) in the time domain.
