Answer:

it is correct you are right

Answer: x = \(\sqrt{320}, or 17.8885438\)

Step-by-step explanation:

According to the pythagorean theorem, a^2 + b^2 = c^2.

As such, 4^2 + x^2 = (4sqrt5)^2

16 + x^2 = 80

x^2 = 64

x = 8.

Thus, the dashed line in the center is 8.

Simply plug this into the pythagorean theorem as well.

8^2+16^2=p^2

p^2 = 320

p = 17.8885438, or sqrt 320

Step-by-step explanation:

The measure of angle formed from the angle bisector PC- ∠CPD is 70°.

Here the question says that here we have an angle, ∠RPD. Now, there os a line PC from point P that bisects the angle, ∠RPD. Now, the given information states that ∠RPD measures 140°. We need to find the measure of ∠CPD.

According to the question,

the angle ∠RPD is bisected by the line PC.

An angle bisector is that line, line segment or ray, that divides an angle equally into 2 halves.

We know that ∠RPD = 140°

Now,  since PC bisects ∠RPD, the angle ∠CPD resulted from it would be half of that of ∠RPD

Hence ∠CPD = 70°.

Let's start by finding the surface area of the parametric surface given by

To find the surface area, we need to evaluate the integral:

where

The surface area can be expressed in terms of a double integral over the parameter domain of the surface, which is the square [0,1] × [0,1]:

First, we need to compute the partial derivatives:

Then, we can compute the cross product:

Finally, we can compute the magnitude of the cross product:

Thus, the surface area of the parametric surface given by

is

Now, to find the surface area of the parametric surface given by

we can use the same method. The partial derivatives are:

The cross product is:

And the magnitude of the cross product is:

Thus, the surface area of the parametric surface given by

is

Therefore, the surface area of the second parametric surface is 2 times the surface area of the first parametric surface, which is 2.

The given parametric surface has a surface area given by 2π.

To find the surface area of the parametric surface given by  with , we need to use the formula for the surface area of a parametric surface:

A = ∫∫ ||(∂f/∂u) x (∂f/∂v)|| dudv

where ||(∂f/∂u) x (∂f/∂v)|| is the magnitude of the cross product of the partial derivatives of the parametric equations, and dudv is the area element in the u-v plane.

For the given parametric surface, we have:

x = u
y = v
z = uv

So, the partial derivatives are:

∂f/∂u = i + vj
∂f/∂v = ui + uk

Taking the cross product, we get:

(∂f/∂u) x (∂f/∂v) = -vj + uuk - vk

Taking the magnitude, we get:

||(∂f/∂u) x (∂f/∂v)|| = √(1 + u² + v²)

So, the surface area is:

A = ∫∫ √(1 + u² + v²) dudv

To evaluate this integral, we can use a change of variables:

x = u
y = v
z = √(1 + u² + v²)

which gives us a surface that is a hemisphere of radius 1. The surface area of a hemisphere is given by:

A = 2πr²

So, in this case, the surface area is:

A = 2π(1)² = 2π

Therefore, the surface area of the parametric surface given by  with  is 2π.

Option b.) to provide a surface finish is correct answer. For the metal removal process, the metal removal is more (not negligible), and for surface finishing the metal removal is negligible.

Surfacing removes a small amount of material from the surface compared to other metal cutting processes. However, a small amount of material is removed during surface preparation compared to this method. Although there is definitely a removal of material from the surface.

Why surface finishing is required :- Surface finish can affect a part's resistance to wear and fatigue. Promotes or destroys effective lubrication. Increase or decrease friction and/or wear with mating parts. and resist corrosion.

Surface Finishing Work Methods :-

⇒Finishing is the process of modifying the surface of a manufactured part to achieve a desired appearance, facilitate bonding, or increase durability.

⇒ All finishing processes applied to manufactured parts depend on the material of the part (plastic or metal).

⇒Surface finish charts are usually measured in microns or microinches. The surface finish measurement describes the overall texture of a surface, characterized by surface waviness, position, and surface roughness.

The probability that a randomly selected fish is a large, red fish is 0.25 or 25%.

To find the probability that a randomly selected fish is a large, red fish, we need to consider both the probability of selecting a large fish and the probability of selecting a red fish among the large fish.

Assuming an equal number of large and small fish, the probability of selecting a large fish is 0.5 (or 1/2).

Among the large fish, the probability of selecting a red fish is also 0.5 (or 1/2).

To find the overall probability, we multiply the probabilities of the individual events:

Probability of selecting a large, red fish = Probability of selecting a large fish × Probability of selecting a red fish among the large fish

Probability of selecting a large, red fish = 0.5 × 0.5

Probability of selecting a large, red fish = 0.25

Therefore, the probability that a randomly selected fish is a large, red fish is 0.25 or 25%.

The value of a(t) is -1 and b(t) is 55 + \(e^t\)

No, the given equation y' - y = 55 + \(e^t\) is not in the standard form of a first-order linear differential equation.

In the method for solving a first-order linear differential equation, an integrating factor is a function used to transform the equation into a form that can be easily solved.

For an equation in the standard form y' + a(t)y = b(t), the integrating factor is defined as:

μ(t) = e^∫a(t)dt

To solve the equation, you multiply both sides of the equation by the integrating factor μ(t) and then simplify. This multiplication helps to make the left side of the equation integrable and simplifies the process of finding the solution.

To put it in standard form, we need to rewrite it as y' + a(t)y = b(t).

Comparing the given equation with the standard form, we can identify:

a(t) = -1

b(t) = 55 + \(e^t\)

The derivative function is dy/dx = (1 - t) / (\(6t^3\)) and \(d^2y/dx^2\) = \((-1 / (6t^3))\)- (3 / \((2t^4)\)

To find dy/dx, we need to differentiate y with respect to t and x with respect to t, and then divide the two derivatives.

Given:

\(x = 3t^4 + 7\)

\(y = 2t - t^2\)

Differentiating y with respect to t:

dy/dt = 2 - 2t

Differentiating x with respect to t:

\(dx/dt = 12t^3\)

Now, to find dy/dx, we divide dy/dt by dx/dt:

\(dy/dx = (2 - 2t) / (12t^3)\)

To simplify this expression further, we can divide both the numerator and denominator by 2:

\(dy/dx = (1 - t) / (6t^3)\)

The second derivative \(d^2y/dx^2\)represents the rate of change of the derivative dy/dx with respect to x. To find \(d^2y/dx^2\), we differentiate dy/dx with respect to t and then divide by dx/dt.

Differentiating dy/dx with respect to t:

\(d^2y/dx^2 = d/dt((1 - t) / (6t^3))\)

To simplify further, we can expand the differentiation:

\(d^2y/dx^2 = (-1 / (6t^3)) - (3 / (2t^4))\)

The function \(\(f(x, y) = 4xy - x^2 - 6y^2 + 5x + 5\)\) has a local maximum at \(\(\left(\frac{15}{2}, \frac{5}{2}\right)\)\).

To find the local maxima, local minima, and saddle points of the function \(\(f(x, y) = 4xy - x^2 - 6y^2 + 5x + 5\)\), we need to calculate its partial derivatives and analyze their critical points.

Step 1: Calculate the partial derivatives:

\(\(\frac{{\partial f}}{{\partial x}} = 4y - 2x + 5\)\)

\(\(\frac{{\partial f}}{{\partial y}} = 4x - 12y\)\)

Step 2: Set the partial derivatives equal to zero and solve for x and y to find the critical points:

For \(\(\frac{{\partial f}}{{\partial x}} = 0\)\):

4y - 2x + 5 = 0

For \(\(\frac{{\partial f}}{{\partial y}} = 0\)\):

4x - 12y = 0

Solving these two equations simultaneously, we get:

4y - 2x + 5 = 0

4x - 12y = 0

From the second equation, we have (x = 3y). Substituting this into the first equation:

\(\(4y - 2(3y) + 5 = 0\)\)

\(\(4y - 6y + 5 = 0\)\)

\(\(-2y + 5 = 0\)\)

\(\(2y = 5\)\)

\(\(y = \frac{5}{2}\)\)

Substituting the value of (y) back into (x = 3y):

\(\(x = 3 \left(\frac{5}{2}\right)\)\)

\(\(x = \frac{15}{2}\)\)

So, the critical point is \(\(\left(\frac{15}{2}, \frac{5}{2}\right)\)\).

Step 3: Analyze the critical points to determine if they are local maxima, local minima, or saddle points.

To classify the critical points, we need to calculate the second-order partial derivatives and evaluate the determinant and the discriminant of the Hessian matrix.

The Hessian matrix is given by:

\(\(H(x, y) = \begin{bmatrix} \frac{{\partial^2 f}}{{\partial x^2}} & \frac{{\partial^2 f}}{{\partial x \partial y}} \\ \frac{{\partial^2 f}}{{\partial y \partial x}} & \frac{{\partial^2 f}}{{\partial y^2}} \end{bmatrix}\)\)

Calculating the second-order partial derivatives:

\(\(\frac{{\partial^2 f}}{{\partial x^2}} = -2\)\)

\(\(\frac{{\partial^2 f}}{{\partial x \partial y}} = 4\)\)

\(\(\frac{{\partial^2 f}}{{\partial y \partial x}} = 4\)\)

\(\(\frac{{\partial^2 f}}{{\partial y^2}} = -12\)\)

Evaluating the Hessian matrix at the critical point \(\(\left(\frac{15}{2}, \frac{5}{2}\right)\)\):

\(\(H\left(\frac{15}{2}, \frac{5}{2}\right) = \begin{bmatrix} -2 & 4 \\ 4 & -12 \end{bmatrix}\)\)

The determinant of the Hessian matrix is:

\(\(\Delta = \frac{{\partial^2 f}}{{\partial x^2}} \cdot \frac{{\partial^2 f}}{{\partial y^2}} - \left(\frac{{\partial^2 f}}{{\partial x \partial y}}\right)^2 = (-2) \cdot (-12) - (4)^2 = 24 - 16 = 8\)\)

The discriminant of the Hessian matrix is:

\(\(D = \frac{{\partial^2 f}}{{\partial x^2}} = -2\)\)

Based on the determinant and discriminant, we can determine the nature of the critical point:

1. If \(\(\Delta > 0\)\) and \(\(D > 0\)\), then the critical point is a local minimum.

2. If \(\(\Delta > 0\)\) and \(\(D < 0\)\), then the critical point is a local maximum.

3. If \(\(\Delta < 0\)\), then the critical point is a saddle point.

4. If \(\(\Delta = 0\)\), further analysis is required (such as higher-order derivatives or other methods).

In this case, we have \(\(\Delta = 8\)\) and \(\(D = -2\)\).

Since \(\(\Delta > 0\)\) and \(\(D < 0\)\), we conclude that the critical point \(\(\left(\frac{15}{2}, \frac{5}{2}\right)\)\) is a local maximum.
