(a). The total mass of the plate is 8g.

(b). Sketch of the plate has been drawn.

(c). The value of bar-x is 3/2.

What is area bounded by the curve?

The length of the appropriate arc of the curve is equal to the area enclosed by a curve, its axis of coordinates, and one of its points.

As given curve is,

y = x² for 0 ≤ x ≤ 2

From the given data,

The constant density of a metal plate is 3 g/cm². The metal plate as a shape bounded by the curve y = x² and the x-axis.

(a). Evaluate the total mass of the plate:

The area of the plate is A = ∫ from (0 to 2) y dx

A = ∫ from (0 to 2) x² dx

A = from (0 to 2) [x³/3]

A = [(2³/3) -(0³/3)]

A = 8/3.

Hence, the area of the plate is A = 8/3 cm².

and also, the mass is = area of the plate × plate density

Mass = 8/3 cm² × 3 g/cm²

Mass = 8g.

(b). The sketch of the required region shown below.

(c). Evaluate the value of bar-x:

Slice the region into vertical strips of width Δx.

Now, the area of strips = Aₓ(x) × Δx

                                      = x²Δx

Now, the required value of bar-x = [∫xδ Aₓ dx]/Mass

bar-x = [∫xδ Aₓ dx]/Mass.

Substitute values,

bar-x = [∫from (0 to 2) xδ Aₓ dx]/Mass

bar-x = [3∫from (0 to 2) x³ dx]/8

bar-x = [3/8 ∫from (0 to 2) x³ dx]

Solve integral,

bar-x = [3/8 {from (0 to 2) x⁴/4}]

bar-x = 3/8 {(2⁴/4) -(0⁴/4)}

bar-x = 3/8 {4 - 0}

bar-x = 3/2.

Hence, the value of all sub-parts has been obtained.

The average value of f(x) = 12 - |x| over the interval [-12, 12] is 12.

To find the average value of a function f(x) over an interval [a, b], we need to calculate the definite integral of the function over that interval and divide it by the width of the interval (b - a).

In this case, the function is f(x) = 12 - |x| and the interval is [12, 12]. However, note that the interval [12, 12] has zero width, so we cannot compute the average value of the function over this interval.

To have a non-zero width interval, we need to choose two distinct endpoints within the range of the function. For example, if we consider the interval [-12, 12], we can proceed with calculating the average value.

First, let's find the definite integral of f(x) = 12 - |x| over the interval [-12, 12]:

∫[-12, 12] (12 - |x|) dx = ∫[-12, 0] (12 - (-x)) dx + ∫[0, 12] (12 - x) dx

= ∫[-12, 0] (12 + x) dx + ∫[0, 12] (12 - x) dx

= [12x + (x^2)/2] from -12 to 0 + [12x - (x^2)/2] from 0 to 12

= (12(0) + (0^2)/2) - (12(-12) + ((-12)^2)/2) + (12(12) - (12^2)/2) - (12(0) + (0^2)/2)

= 0 - (-144) + 144 - 0

= 288

Now, divide the result by the width of the interval: 12 - (-12) = 24.

Average value of f(x) = (1/24) * 288 = 12.

Therefore, the average value of f(x) = 12 - |x| over the interval [-12, 12] is 12.

To find f'(1), the derivative of the function f(x), given the equation f(x) + x * [f(x)] = 8x + 2 and f(1) = 2, we can differentiate both sides of the equation with respect to x.

Differentiating the equation f(x) + x * [f(x)] = 8x + 2:

f'(x) + [f(x) + x * f'(x)] = 8

Combining like terms:

f'(x) + x * f'(x) + f(x) = 8

Now, we substitute x = 1 into the equation and use the given initial condition f(1) = 2:

f'(1) + 1 * f'(1) + f(1) = 8

2f'(1) + f(1) = 8

Plugging in the value of f(1) = 2:

2f'(1) + 2 = 8

Simplifying the equation:

2f'(1) = 6

Dividing both sides by 2:

To find the differential dy for the given expression y = ln(sec(32^2 - 23 + 5)), we can use the chain rule of differentiation.

The chain rule states that if we have a composite function, such as f(g(x)), then the derivative of f(g(x)) with respect to x is given by the derivative of f with respect to g multiplied by the derivative of g with respect to x.

In this case, we have y = ln(sec(32^2 - 23 + 5)), where the inner function is g(x) = sec(32^2 - 23 + 5) and the outer function is f(u) = ln(u).

Let's differentiate step by step:

Find the derivative of the outer function:

The helicoid, or spiral ramp, is a surface defined by the vector equation r(u, v) = u cos(v)i + u sin(v)j + vk, where u ranges from 1 to 3 and v ranges from 0 to 2π.

To find the area of this surface, we can use the formula for surface area of a parametric surface. The surface area element dS is given by the magnitude of the cross product of the partial derivatives of r with respect to u and v, multiplied by du dv.

The partial derivatives of r with respect to u and v are:

∂r/∂u = cos(v)i + sin(v)j + k

∂r/∂v = -u sin(v)i + u cos(v)j

Taking the cross product, we get:

∂r/∂u × ∂r/∂v = (u cos^2(v) + u sin^2(v))i + (u sin(v) cos(v) - u sin(v) cos(v))j + (u cos(v) + u sin(v))k

= u(i + k)

The magnitude of ∂r/∂u × ∂r/∂v is |u|√2.

The surface area element is given by |u|√2 du dv.

Integrating this expression over the given range of u and v, we find the area of the helicoid surface:

Area = ∫∫ |u|√2 du dv

= ∫[0,2π] ∫[1,3] |u|√2 du dv

Evaluating this double integral will give us the area of the helicoid surface.

The answer is [tex]12\sqrt{5} /\pi[/tex] for the spherical coordinates in the given equation.[tex]x^2 + y^2 + z^2 = r^2[/tex]

The given cone's equation is z = [tex]13x^2[/tex] + 3y. Here, x, y, and z are all positive, and the vertex is at the origin (0,0,0). The sphere x² + y² + z² = r² has a radius of r and is centered at the origin. We have two spheres here, one with a radius of 1 and the other with a radius of 4 (since 16 = [tex]4^2[/tex]). In spherical coordinates, the variables r, θ, and φ are used to describe a point (r, θ, φ) in space.

The radius is r, which is the distance from the origin to the point. The angle φ, which is measured from the positive z-axis, is called the polar angle. The azimuth angle θ is measured from the positive x-axis, which lies in the xy-plane. θ varies from 0 to [tex]2\pi[/tex], and φ varies from 0 to π.

According to the problem, the cone's equation is given by z = 13x² + 3y, and the spheres have equations x² + y² + z² = 16 [tex]\pi[/tex]and [tex]x^2 + y^2 + z^2 = 16[/tex].

Using spherical coordinates, we may rewrite these equations as follows:r = 1, 0 ≤ φ ≤ π, 0 ≤ θ ≤ 2πr = 4, 0 ≤ φ ≤ π, 0 ≤ θ ≤[tex]2\pi z = 13r² sin² φ + 3r sin φ cos θ[/tex]

To find the volume of the solid within the cone and between the spheres, we must first integrate over the cone and then over the two spheres.To integrate over the cone, we'll use the following equation:[tex]∫∫∫ f(r, θ, φ) r² sin φ dr dφ dθ[/tex]where the integration limits for r, φ, and θ are as follows:0 ≤ r ≤ [tex][tex]13r² sin² φ + 3r sin φ cos θ0 ≤ φ ≤ π0 ≤ θ ≤ 2π[/tex][/tex]

We can integrate over the two spheres using the following equation:∫∫∫ f(r, θ, φ) r² sin φ dr dφ dθ, where the integration limits for r, φ, and θ are as follows:r =[tex]1, 0 ≤ φ ≤ π, 0 ≤ θ ≤ 2πr = 4, 0 ≤ φ ≤ π, 0 ≤ θ ≤ 2π[/tex]

So the total volume V is given by:V = ∫∫∫ f(r, θ, φ) r² sin φ dr dφ dθ + ∫∫∫ f(r, θ, φ) r² sin φ dr dφ dθ, where f(r, θ, φ) = 1.To solve the integral over the cone, we need to multiply the volume element by the Jacobian, which is r² sin φ.

We get:[tex]∫∫∫ r² sin φ dr dφ dθ[/tex]= [tex]∫₀^π ∫₀^(2π) ∫₀^(13r² sin² φ + 3r sin φ cos θ) r² sin φ dr dφ dθ[/tex]

Here is the process of simplification:[tex]∫₀^π sin φ dφ = 2∫₀^(2π) dθ = 2π∫₀^π (13r⁴ sin⁴ φ + 6r³ sin³ φ cos θ[/tex]+ [tex]9r² sin² φ cos² θ) dφ = 2π[13/5 r⁵/5 sin⁵ φ + 3/4 r⁴/4 sin⁴ φ cos θ + 9/2 r³/3 sin³ φ cos² θ][/tex] from 0 to [tex]\pi[/tex] and from 0 to [tex]2\pi[/tex].

Using this same method, we may now solve the integral over the two spheres[tex]:∫∫∫ r² sin φ dr dφ dθ[/tex]=  [tex]∫₀^π ∫₀^(2π) ∫₀¹  r² sin φ dr dφ dθ + ∫₀^π ∫₀^(2π) ∫₀⁴ r² sin φ dr dφ dθ[/tex]

By integrating with respect to r, φ, and θ, we may get:[tex]∫₀^π sin φ dφ = 2∫₀^(2π) dθ = 2π∫₀¹ r² dr = 1/3 ∫₀^π sin φ dφ[/tex] = [tex]2π/3∫₀^π sin φ dφ = 2∫₀^(2π) dθ = 4π/3∫₀⁴ r² dr = 64π/3[/tex]

Thus, the total volume V is:V = [tex][2\pi (13/5 + 27/2) + 4\pi (1/3 - 4/3)] - 4\pi /3 = 60/5\pi[/tex] = [tex]12\sqrt{5} /\pi[/tex]. So, the answer is [tex]12\sqrt{5} /\pi[/tex].

The exact length of the curve x=(1/3)√y(y-3), where y ranges from 4 to 16, is approximately 4.728 units.

To find the exact length of the curve defined by the equation x = (1/3)√y(y - 3), where y ranges from 4 to 16, we can use the arc length formula for a curve in Cartesian coordinates.

The arc length formula for a curve defined by the equation y = f(x) over the interval [a, b] is:

L =[tex]\int\limits^a_b[/tex]√(1 + (f'(x))²) dx

In this case, we need to find f'(x) and substitute it into the arc length formula.

Given x = (1/3)√y(y - 3), we can solve for y as a function of x:

x = (1/3)√y(y - 3)

3x = √y(y - 3)

9x² = y(y - 3)

y² - 3y - 9x = 0

Using the quadratic formula, we find:

y = (3 ± √(9 + 36x²)) / 2

Since y is non-negative, we take the positive square root:

y = (3 + √(9 + 36x²)) / 2

Differentiating with respect to x, we get:

dy/dx = 18x / (2√(9 + 36x²))

= 9x / √(9 + 36x²)

Now, substitute this expression for dy/dx into the arc length formula:

L = ∫[4,16] √(1 + (9x / √(9 + 36x²))²) dx

Simplifying, we have

L = ∫[4,16] √(1 + (81x² / (9 + 36x²))) dx

L = ∫[4,16] √((9 + 36x² + 81x²) / (9 + 36x²)) dx

L = ∫[4,16] √((9 + 117x²) / (9 + 36x²)) dx

we can use the substitution method.

Let's set u = 9 + 36x², then du = 72x dx.

Rearranging the equation, we have x² = (u - 9) / 36.

Now, substitute these values into the integral

∫[4,16] √((9 + 117x²) / (9 + 36x²)) dx = ∫[4,16] √(u/u) * (1/6) * (1/√6) * (1/√u) du

Simplifying further, we get

(1/6√6) * ∫[4,16] (1/u) du

Taking the integral, we have

(1/6√6) * ln|u| |[4,16]

Substituting back u = 9 + 36x²:

(1/6√6) * ln|9 + 36x²| |[4,16]

Evaluating the integral from x = 4 to x = 16, we have

(1/6√6) * [ln|9 + 36(16)| - ln|9 + 36(4)^2|]

Simplifying further:

L = (1/6√6) * [ln|9 + 9216| - ln|9 + 576|]

Simplifying further, we have:

L = (1/6√6) * [ln(9225) - ln(585)]

Calculating the numerical value of the expression, we find

L ≈ 4.728 units (rounded to three decimal places)

The maximum value of f(x, y) on the ellipse x^2 + 9y^2 = 1 is 443/71√3, and the minimum value is -443/71√3.

We can use the method of Lagrange multipliers. Let's define the Lagrangian function L(x, y, λ) as:

L(x, y, λ) = f(x, y) - λ(g(x, y)), where g(x, y) represents the constraint equation x^2 + 9y^2 = 1.

The partial derivatives of L with respect to x, y, and λ are:

∂L/∂x = 7 - 2λx,

∂L/∂y = 1 - 18λy,

∂L/∂λ = -(x^2 + 9y^2 - 1).

Setting these partial derivatives equal to zero, we have the following system of equations:

7 - 2λx = 0,

1 - 18λy = 0,

x^2 + 9y^2 - 1 = 0.

From the second equation, we get λ = 1/(18y), and substituting this into the first equation, we have:

7 - (2/18y)x = 0,

x = (63/2)y.

Substituting this value of x into the third equation, we get:

(63/2y)^2 + 9y^2 - 1 = 0,

(3969/4)y^2 + 9y^2 - 1 = 0,

(5049/4)y^2 = 1,

y^2 = 4/5049,

y = ±√(4/5049) = ±(2/√5049) = ±(2/71√3).

Substituting these values of y into x = (63/2)y, we get the corresponding values of x:

x = (63/2)(2/71√3) = 63/71√3, or

x = (63/2)(-2/71√3) = -63/71√3.

Therefore, the critical points on the ellipse are:

(63/71√3, 2/71√3) and (-63/71√3, -2/71√3).

To find the maximum and minimum values of f(x, y) on the ellipse, we substitute these critical points and the endpoints of the ellipse into the function f(x, y) = 7x + y, and compare the values.

Considering the function at the critical points:

f(63/71√3, 2/71√3) = 7(63/71√3) + 2/71√3 = 441/71√3 + 2/71√3 = (441 + 2)/71√3 = 443/71√3,

f(-63/71√3, -2/71√3) = 7(-63/71√3) - 2/71√3 = -441/71√3 - 2/71√3 = (-441 - 2)/71√3 = -443/71√3.

Now, we consider the function at the endpoints of the ellipse:

When x = 1, we have y = 0 from the equation of the ellipse. Substituting these values into f(x, y), we get:

f(1, 0) = 7(1) + 0 = 7.

f(-1, 0) = 7(-1) + 0 = -7.

Therefore, the maximum value of f(x, y) on the ellipse x^2 + 9y^2 = 1 is 443/71√3, and the minimum value is -443/71√3.

To convert the angle a = 12.3699 degrees to degrees, minutes, and seconds form, we need to separate the whole number of degrees, minutes, and seconds.

First, we take the whole number of degrees, which is 12.

Next, we focus on the decimal part, 0.3699, which represents the remaining minutes and seconds.

To convert the decimal part to minutes, we multiply it by 60. So, 0.3699 * 60 = 22.194.

The whole number part of 22.194 represents the minutes, which is 22.

Finally, we need to convert the remaining decimal part, 0.194, to seconds. We multiply it by 60, which gives us 0.194 * 60 = 11.64.

Therefore, the angle a = 12.3699 degrees can be expressed as 12 degrees, 22 minutes, and 11.64 seconds when written in degrees, minutes, and seconds form.

Zeno covered a total distance of (1.75^k - 1) miles by the end of week k in his training regimen, where k represents the number of weeks.



In Zeno's training regimen, he starts by running one mile in the first week. From there, each subsequent week, Zeno increases the distance he runs by 1.75 times the previous week's distance. This can be represented as a geometric sequence, where the common ratio is 1.75.

To calculate the total distance covered by the end of week k, we need to find the sum of the terms in this geometric sequence up to the kth term. The formula to calculate the sum of a geometric sequence is S = a * (r^k - 1) / (r - 1), where S is the sum, a is the first term, r is the common ratio, and k is the number of terms.

In this case, Zeno's first term (a) is 1 mile, the common ratio (r) is 1.75, and the number of terms (k) is the number of weeks. So, the total distance covered by the end of week k is given by (1.75^k - 1) miles.For example, if Zeno trains for 5 weeks, the total distance covered would be (1.75^5 - 1) = (7.59375 - 1) = 6.59375 miles.

Therefore, with a 90% confidence level, we estimate that the proportion of the voting population that prefers candidate A is between 0.252 and 0.328, rounded to three decimal places.

To find the critical value for a confidence level of 95%, we use the standard normal distribution.

Since the sample size is large (600 people sampled), we can use the normal approximation to the binomial distribution. The formula for the confidence interval is:

Estimate ± (Critical Value) * (Standard Error)

In this case, we have 174 out of 600 people who preferred candidate A, so the proportion is 174/600 = 0.29.

To find the critical value, we need to determine the z-score corresponding to a 95% confidence level. Using a standard normal distribution table or a calculator, we find that the z-score for a 95% confidence level is approximately 1.96.

Next, we need to calculate the standard error. The formula for the standard error in this case is:

Standard Error = sqrt((p * (1 - p)) / n)

where p is the sample proportion (0.29) and n is the sample size (600).

Plugging in the values, we have:

Standard Error = sqrt((0.29 * (1 - 0.29)) / 600) ≈ 0.0195

Now, we can calculate the confidence interval:

0.29 ± (1.96 * 0.0195)

The lower bound of the confidence interval is 0.29 - (1.96 * 0.0195) ≈ 0.2519, and the upper bound is 0.29 + (1.96 * 0.0195) ≈ 0.3281.

In 1948:

Total overall cost = 124 × 66

Total overall cost = $8,184.

In 1967:

Total overall cost = $15,787.25 × 66

Total overall cost = $1,041,958.5.

Mark up price = 1,041,958.5 - 8184.

Mark up price = 1,033,774.5

1,033,774.5/8,184 = x/100

x = 1,033,77450/8,184

x = 12,631.65%

The solution to the system of inequalities is option C: (1, 1). The system of inequalities typically consists of multiple equations with inequality signs. However, the given options are not in the form of inequalities.

In the given system of inequalities, option d) satisfies all the given conditions. Let's analyze the system of inequalities and understand why option d) is the solution.

The inequalities are not explicitly mentioned, so we'll assume a general form. Let's consider two inequalities:

x > 0

y > x + 2

In option d), we have x = 2 and y = 4.

For the first inequality, x = 2 satisfies the condition x > 0 since 2 is greater than 0.

For the second inequality, y = 4 satisfies the condition y > x + 2. When we substitute x = 2 into the inequality, we get 4 > 2 + 2, which is true.

Therefore, option d) 2,4 satisfies both inequalities and is the solution to the given system.

The exact area enclosed by the curve y = x^2(4 - x)^2 and the x-axis is approximately 34.1333 square units.

Let's integrate the function y = x^2(4 - x)^2 with respect to x over the interval [0, 4] to find the area:

A = ∫[0 to 4] x^2(4 - x)^2 dx

To simplify the calculation, we can expand the squared term:

A = ∫[0 to 4] x^2(16 - 8x + x^2) dx

Now, let's distribute and integrate each term separately:

A = ∫[0 to 4] (16x^2 - 8x^3 + x^4) dx

Integrating term by term:

A = [16/3 * x^3 - 2x^4 + 1/5 * x^5] evaluated from 0 to 4

Now, let's substitute the values of x into the expression:

A = [16/3 * (4)^3 - 2(4)^4 + 1/5 * (4)^5] - [16/3 * (0)^3 - 2(0)^4 + 1/5 * (0)^5]

Simplifying further:

A = [16/3 * 64 - 2 * 256 + 1/5 * 1024] - [0 - 0 + 0]

A = [341.333 - 512 + 204.8] - [0]

A = 34.1333 - 0

A = 34.1333

Using implicit differentiation the value of y' is 2.

To find the derivative of y with respect to x (y'), we'll use implicit differentiation on the equation y - 2x + 7 = 0.

Differentiating both sides of the equation with respect to x:

d/dx(y) - d/dx(2x) + d/dx(7) = 0

y' - 2 + 0 = 0

Simplifying:

y' = 2

So the derivative of y with respect to x, y', is equal to 2.

To evaluate y' at the point (2,1), substitute x = 2 and y = 1 into the derived expression for y':

y' (2,1) = 2

The marginal cost function (MC) for the given cost function C(x) = 200 + 15x + 0.04x² is MC(x) = 15 + 0.08x.

The marginal cost (MC) represents the additional cost incurred when producing one more unit of a product. To find the marginal cost function, we need to differentiate the given cost function, C(x), with respect to the number of units (x).

Given that C(x) = 200 + 15x + 0.04x², let's differentiate it with respect to x:

MC(x) = dC(x)/dx

Differentiating each term separately, we get:

MC(x) = d/dx (200) + d/dx (15x) + d/dx (0.04x²)

Since the derivative of a constant is zero, the first term becomes:

MC(x) = 0 + 15 + d/dx (0.04x²)

Now, we differentiate the third term using the power rule:

MC(x) = 15 + d/dx (0.04 * 2x)

Simplifying further:

MC(x) = 15 + 0.08x

Answer:

Step-by-step explanation:

The statement "A $30 maximum charge on an automobile inspection is an example of a price ceiling" is true.

A price ceiling is a government-imposed restriction on the maximum price that can be charged for a particular good or service. It is designed to protect consumers and ensure affordability. In the case of the $30 maximum charge on an automobile inspection, it represents a price ceiling because it sets a limit on the amount that can be charged for this service.

By implementing a price ceiling of $30, the government aims to prevent inspection service providers from charging excessively high prices that could be burdensome for consumers. This measure helps to maintain affordability and accessibility to automobile inspections for a wider population.

Therefore, the statement is true, as a $30 maximum charge on an automobile inspection aligns with the concept of a price ceiling

The series (ii) 4n³-2n +1 is the one that diverges, while the series (-1)-1 Sn (+1) and (i) 4n³-2n +1 are alternating series.

(a) The series (-1)-1 Sn (+1) and (i) 4n³-2n +1 are alternating series because the signs of their terms alternate between positive and negative. The series (-1)-1 Sn (+1) has a negative term followed by a positive term, while the series (i) 4n³-2n +1 has terms that alternate between positive and negative values.

(b) The series (ii) 4n³-2n +1 diverges. To determine this, we can look at the behavior of the terms as n approaches infinity.

In the series (ii), as n approaches infinity, the dominant term becomes 4n³. Since the leading term has a non-zero coefficient (4) and an exponent greater than 1, the series will diverge. The other terms (-2n + 1) become insignificant compared to the dominant term as n becomes large.

When a series diverges, it means that the sum of the terms does not approach a finite value as n goes to infinity. In the case of (ii) 4n³-2n +1, the terms keep growing without bound as n increases, leading to divergence.

Answer:

The position function of the particle moving along the s-axis is s(t) = (1/12) * t^4 + (1/6) * t^3 - 3t^2.

Step-by-step explanation:

To find the position function of the particle, we'll need to integrate the given acceleration function, a(t), twice.

Given:

a(t) = t^2 + t - 6, v(0) = 0, s(0) = 0

First, let's integrate the acceleration function, a(t), to obtain the velocity function, v(t):

∫ a(t) dt = ∫ (t^2 + t - 6) dt

Integrating term by term:

v(t) = (1/3) * t^3 + (1/2) * t^2 - 6t + C₁

Using the initial condition v(0) = 0, we can find the value of the constant C₁:

0 = (1/3) * (0)^3 + (1/2) * (0)^2 - 6(0) + C₁

0 = 0 + 0 + 0 + C₁

C₁ = 0

Thus, the velocity function becomes:

v(t) = (1/3) * t^3 + (1/2) * t^2 - 6t

Next, let's integrate the velocity function, v(t), to obtain the position function, s(t):

∫ v(t) dt = ∫ [(1/3) * t^3 + (1/2) * t^2 - 6t] dt

Integrating term by term:

s(t) = (1/12) * t^4 + (1/6) * t^3 - 3t^2 + C₂

Using the initial condition s(0) = 0, we can find the value of the constant C₂:

0 = (1/12) * (0)^4 + (1/6) * (0)^3 - 3(0)^2 + C₂

0 = 0 + 0 + 0 + C₂

C₂ = 0

Thus, the position function becomes:

s(t) = (1/12) * t^4 + (1/6) * t^3 - 3t^2

Therefore, the position function of the particle moving along the s-axis is s(t) = (1/12) * t^4 + (1/6) * t^3 - 3t^2.

To find the probability, we need to determine the total number of possible committee combinations and the number of combinations with at least one man. There are 9 people (6 women + 3 men) to choose from, and we want to choose a committee of 4.

Total combinations = C(9,4) = 9! / (4!(9-4)!) = 126
Combinations of only women = C(6,4) = 6! / (4!(6-4)!) = 15

To find the probability of at least one man, we'll subtract the probability of selecting only women from 1:

P(at least one man) = 1 - (15/126) = 1 - 0.119 = 0.881

The triangle AABC can be visualized in three-dimensional space using the given points A(3, 1, 4), B(0, 2, 2), and C(1, 2, 6).

To determine if the triangle is equilateral, isosceles, or scalene, we need to calculate the lengths of the three sides of the triangle. The lengths of the sides can be found using the distance formula, which measures the distance between two points in space.

Calculating the lengths of the sides:

Side AB: √[(3-0)² + (1-2)² + (4-2)²] = √(9 + 1 + 4) = √14

Side AC: √[(3-1)² + (1-2)² + (4-6)²] = √(4 + 1 + 4) = √9 = 3

Side BC: √[(0-1)² + (2-2)² + (2-6)²] = √(1 + 0 + 16) = √17

By comparing the lengths of the three sides, we can determine the nature of the triangle:

- If all three sides are equal, i.e., AB = AC = BC, then the triangle is equilateral.

- If any two sides are equal, but the third side is different, then the triangle is isosceles.

- If all three sides have different lengths, then the triangle is scalene.

In this case, AB = √14, AC = 3, and BC = √17. Since all three sides have different lengths, the triangle AABC is a scalene triangle.

To determine the intervals of continuity for the function f(x) = (x - 3) / (x^2 + 3x - 18), we first need to identify any discontinuities. Discontinuities occur when the denominator is equal to zero. We can factor the denominator as follows:

x^2 + 3x - 18 = (x - 3)(x + 6)

The denominator is equal to zero when x = 3 or x = -6. Therefore, the function has discontinuities at x = 3 and x = -6.

Now, we can describe the intervals of continuity using interval notation:

(-∞, -6) ∪ (-6, 3) ∪ (3, ∞)

For the identified discontinuities, the conditions of continuity that are not satisfied are:

A. There is a discontinuity at x = c where f(c) is not defined.
C. There is a discontinuity at x = c where lim x→c f(x) does not exist.

In summary, the function f(x) is continuous on the intervals (-∞, -6) ∪ (-6, 3) ∪ (3, ∞) and has discontinuities at x = 3 and x = -6, with conditions A and C not being satisfied.

The answer is:

The interval on which the function is continuous is (-∞, -6) U (-6, 3) U (3, +∞).

The discontinuities are x = -6 and x = 3.

The conditions of continuity that are not satisfied are B and C.

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

To determine the intervals on which the function is continuous, we need to check for any potential discontinuities. The function is continuous for all values of x except where the denominator is equal to zero, since division by zero is undefined.

To find the discontinuities, we set the denominator equal to zero and solve for x:

x² + 3x - 18 = 0

Factoring the quadratic equation, we have:

(x + 6)(x - 3) = 0

Setting each factor equal to zero, we find two possible values for x:

x + 6 = 0 --> x = -6

x - 3 = 0 --> x = 3

Therefore, the function has two potential discontinuities at x = -6 and x = 3.

Now, we can analyze the conditions of continuity for these potential discontinuities:

A. There is a discontinuity at x = c where f(c) is not defined.

Since f(c) is defined for all values of x, this condition is not met.

B. There is a discontinuity at x = c where lim x→c f(x) ≠ f(c).

To determine this condition, we need to evaluate the limit of the function as x approaches the potential discontinuity points:

lim x→-6 (x - 3) / (x² + 3x - 18) = (-6 - 3) / ((-6)² + 3(-6) - 18) = -9 / 0

Similarly,

lim x→3 (x - 3) / (x^2 + 3x - 18) = (3 - 3) / (3^2 + 3(3) - 18) = 0 / 0

From the calculations, we can see that the limit at x = -6 is undefined (not equal to -9) and the limit at x = 3 is also undefined (not equal to 0).

C. There is a discontinuity at x = c where lim x→c f(x) does not exist.

Since the limits at x = -6 and x = 3 do not exist, this condition is met.

D. There are no discontinuities; f(x) is continuous.

Since we found that there are two potential discontinuities, this choice is not applicable.

Therefore, the answer is:

The interval on which the function is continuous is (-∞, -6) U (-6, 3) U (3, +∞).

The discontinuities are x = -6 and x = 3.

The conditions of continuity that are not satisfied are B and C.
