How to determine the inventory cost by the average cost methods for FIFO and LIFO?

For sin the expression [tex]Qiv sin(A)/(2)[/tex] can be simplified using trigonometric identities.

Trigonometric identities are equations involving trigonometric functions that are true for all values of the variables within their domains. These identities are useful in simplifying trigonometric expressions and solving trigonometric equations. Some common identities include the Pythagorean identity, which relates the trigonometric functions of sine, cosine, and tangent, and the double-angle identities, which express trigonometric functions of twice the angle in terms of functions of the original angle.

First, we can recognize that Qiv is the same as 1/4 of the unit circle or 90 degrees. Therefore, [tex]Qiv sin(A)[/tex] can be simplified to sin(A + 90).

Using the identity [tex]sin(A + B) = sin(A)cos(B) + cos(A)sin(B)[/tex], we can rewrite [tex]sin(A + 90)[/tex] as:

[tex]sin(A)cos(90) + cos(A)sin(90)[/tex]

Since [tex]cos(90) = 0 \\sin(90) = 1[/tex], this:

[tex]sin(A) * 0 + cos(A) * 1[/tex]

Which simplifies to just cos(A).

Therefore, the expression [tex]Qiv sin(A)/(2)[/tex] is equivalent to cos(A)/2.

∠ B = 82°

Step-by-step explanation:

complementary angles sum to 90° , then

x - 19 + 3x + 1 = 90

4x - 18 = 90 ( add 18 to both sides )

4x = 108 ( divide both sides by 4 )

x = 27

The coordinates of the image after the translation are:

A′(−1, 1), B′(7, 1), C′(3, 5)

So the answer is (D) A′(−1, 1), B′(7, 1), C′(3, 5).

What are coordinates ?

Coordinates are pairs of numbers that locate a point in a space or on a plane. In two-dimensional space, or the Cartesian plane, a point is located by an ordered pair of real numbers (x, y), where x represents the horizontal distance and y represents the vertical distance. These numbers are called the coordinates of the point.

The horizontal line is called the x-axis, and the vertical line is called the y-axis. The point where the x-axis and y-axis intersect is called the origin, and it is assigned the coordinates (0, 0).

According to the question:
To translate a figure, we add or subtract a constant value to the x and/or y coordinates of each vertex. In this case, we want to translate triangle ABC 7 units to the right. So, we will add 7 to the x-coordinate of each vertex.

The coordinates of A are (-8, 1). Adding 7 to the x-coordinate gives:

A′ = (-8 + 7, 1) = (-1, 1)

The coordinates of B are (0, 1). Adding 7 to the x-coordinate gives:

B′ = (0 + 7, 1) = (7, 1)

The coordinates of C are (-4, 5). Adding 7 to the x-coordinate gives:

C′ = (-4 + 7, 5) = (3, 5)

Therefore, the coordinates of the image after the translation are:

A′(−1, 1), B′(7, 1), C′(3, 5)

So the answer is (D) A′(−1, 1), B′(7, 1), C′(3, 5).

Thus, A = -16/3

It displays a regular pentagon with centre point A. From each point, a line is traced to the centre point A. Triangles ABC are made. One of the regular pentagon's central angles measures 72°. In triangle ABC, one of the congruent base angles has a measure of 54.

In a regular pentagon, each of the five central angles has the same measure, which can be found using the formula:

[tex]Central angle = 360° / Number of sides[/tex]

Since we have a regular pentagon, the number of sides is 5, so:

[tex]Central angle = 360[/tex]°/5

central angle = 72°

Therefore, each central angle in the regular pentagon measures 72°.

Now let's look at triangle ABC. Since the pentagon is regular, all the line segments from the vertices to the centre are of equal length, so triangle ABC is an isosceles triangle with base angles that are congruent. Give one of these basic angles a measure of x.

Since the sum of the interior angles in any triangle is 180°, we can write:

x + x + angle at vertex = 180°

But we know that the angle at the vertex is a central angle of the pentagon, and so it measures 72°. Thus, we can substitute 72° for the angle at the vertex, and we have:

2x + 72° = 180°

Subtracting 72° from both sides, we get:2x = 108°

Dividing by 2, we find:

x = 54°

Therefore, each of the congruent base angles in triangle ABC measures 54°.

Answer:

the area of the sector in grey is 100.48 square feet.

Step-by-step explanation:

Area of a circle = radius × radius × π

(π ≌ 3.14)

So

the area of the circle in the picture = 16 × 16 × π = 803.84

As the angle in the grey sector is 45°, so the proportion of the grey sector in the circle is

45°/360° = 1/8

Hence why

the area of the grey sector is 1/8 of the area of the circle, which is

803.84 × 1/8 = 100.48

The box with the most volume has 20 centimetres of side length and 20 centimetres of height. The box has a volume of: 8000 cubic centimetres.

We need to employ optimization strategies to determine the box with the highest feasible volume, which has a square base and an open top. Call the box's height h and the square base's side length x, respectively.

V = [tex]x^(2h)[/tex] gives the volume of the box.

The box's overall surface area will be 1600 square centimetres since the material used to create it has a surface area of 1600 square centimetres.

The box's surface area is made up of the areas of its four sides and base (x2) (4xh). We thus have:

[tex]x^2[/tex]+ 4xh = 1600

The volume of the box, which is given by V = [tex]x^(2h)[/tex], is what we wish to maximise.

We can determine h in terms of x using the equation above:

h = (1600 - [tex]x^2[/tex]) / (4x) (4x)

This result is obtained by replacing h with this equation in the volume formula:

V = [tex]x^2[/tex](1600 - [tex]x^2[/tex]) / (4x) (4x)

If we simplify this expression, we get:

V = 400x - [tex]0.25x^3[/tex]

Now, in order to determine the crucial places, we can take the derivative of V with respect to x and put it equal to zero:

[tex]dV/dx = 400 - 0.75x^2 = 0[/tex]

As a result of solving this equation for x,

x = 20

The result of replacing h in the equation with x = 20 is:

h = (1600 - 400) / (4 * 20) = 20

As a result, the box with the maximum volume has 20 centimetres of height and 20 centimetres of side length. The box has a volume of:

8000 cubic centimetres are equal to V = 202 * 20.

Answer:

To evaluate the integral over the region R, we can use the change of variables:

u = 4x

v = 2y

This gives us:

x = u/4

y = v/2

The Jacobian of this transformation is:

| ∂x/∂u ∂x/∂v | = | 1/4 0 |

| ∂y/∂u ∂y/∂v | | 0 1/2 |

So the Jacobian determinant is |J| = (1/4)(1/2) = 1/8.

Using this transformation, the region R is mapped onto the unit circle in the uv-plane, and the equation of the ellipse becomes:

u^2 + v^2/4 = 1/16

The integral becomes:

∫∫R 4x^2 e^(4xy) dA

= 2∫∫S u^2 e^uv/2 (1/8) dA

= (1/4) ∫∫S u^2 e^v/2 dA

where S is the unit circle in the uv-plane.

Now we can use polar coordinates in the uv-plane, with u = r cosθ and v = r sinθ. The integral becomes:

(1/4) ∫∫S r^2 cos^2θ e^(r sinθ/2) r dr dθ

= (1/4) ∫0^2π ∫0^1 r^3 cos^2θ e^(r sinθ/2) dr dθ

The inner integral can be evaluated by integration by parts, letting u = r^2 cos^2θ and dv = e^(r sinθ/2) r dr. This gives:

∫ r^3 cos^2θ e^(r sinθ/2) dr

= r^3 cos^2θ (-2/θ) e^(r sinθ/2) + 2/θ ∫ r^2 cos^2θ e^(r sinθ/2) dr

The integral on the right-hand side can be evaluated by another integration by parts, letting u = r^2 cos^2θ and dv = e^(r sinθ/2) dr, which gives:

∫ r^2 cos^2θ e^(r sinθ/2) dr

= r^2 cos^2θ (-2/θ) e^(r sinθ/2) + 4/θ^2 ∫ r cos^2θ e^(r sinθ/2) dr

We can substitute these results back into the original integral and simplify to get:

∫∫R 4x^2 e^(4xy) dA

= (1/4) ∫0^2π ∫0^1 r^3 cos^2θ e^(r sinθ/2) dr dθ

= (1/2π) ∫0^π ∫0^1 r^3 cos^2θ e^(r sinθ/2) dr dθ

Now we can evaluate the inner integral:

∫0^1 r^3 cos^2θ e^(r sinθ/2) dr = (1/2) ∫0^1 r^2 e^(r sinθ/2) d(r^2)

= (1/2) ∫0^1 u^(1/2) e^(u sinθ/2) du

Letting t = u sin(θ/2) and using the identity sin(θ/2) = 2

Answer:

Step-by-step explanation:

Let's assume Kylie's current age to be x.

According to the problem, Laila is 10 years older than Kylie, so her current age would be (x + 10).

Seventeen years ago, Laila's age would have been (x + 10 - 17) = (x - 7), and Kylie's age would have been (x - 17).

The problem also states that Laila's age 17 years ago was triple Kylie's age 17 years ago, so we can set up the equation:

(x - 7) = 3(x - 17)

Solving for x, we get:

x - 7 = 3x - 51

2x = 44

x = 22

Therefore, Kylie's current age is x = 22, and Laila's current age is (x + 10) = 32.

So, Laila is currently 32 years old and Kylie is currently 22 years old.

Answer:

Laila is currently 32 years old.

Kylie is currently 22 years old.

Step-by-step explanation:

To find the current ages of Laila and Kylie, create and solve a system of linear equations using the given information.

Define the variables:

Given Laila is 10 years older than Kylie:

Given 17 years ago, Laila was triple Kylie's age:

Substitute the first equation into the second equation and solve for K:

⇒ (K + 10) - 17 = 3(K - 17)

⇒ K - 7 = 3K - 51

⇒ K - 7 - K = 3K - 51 - K

⇒ -7 = 2K - 51

⇒ -7 + 51 = 2K - 51 + 51

⇒ 44 = 2K

⇒ 44 ÷ 2 = 2K ÷ 2

⇒ K = 22

Substitute the found value of K into the first equation and solve for L:

⇒ L = K + 10

⇒ L = 22 + 10

⇒ L = 32

Therefore, Laila is currently 32 years old and Kylie is currently 22 years old.

Answer:

Step-by-step explanation: Derivatives are used to find the rate of changes of a quantity with respect to the other quantity. By using the application of derivatives we can find the approximate change in one quantity with respect to the change in the other quantity. Assume we have a function y = f(x), which is defined in the interval [a, a+h], then the average rate of change in the function in the given interval is

(f(a + h)-f(a))/h

Now using the definition of derivative, we can write

f

'

(

a

)

=

lim

h

→

0

f

(

a

+

h

)

−

f

(

a

)

h

which is also the instantaneous rate of change of the function f(x) at a.

Now, for a very small value of h, we can write

f'(a) ≈ (f(a+h) − f(a))/h

or

f(a+h) ≈ f(a) + f'(a)h

This means, if we want to find the small change in a function, we just have to find the derivative of the function at the given point, and using the given equation we can calculate the change. Hence the derivative gives the instantaneous rate of change of a function within the given limits and can be used to find the estimated change in the function f(x) for the small change in the other variable(x).

Approximation Value

Derivative of a function can be used to find the linear approximation of a function at a given value. The linear approximation method was given by Newton and he suggested finding the value of the function at the given point and then finding the equation of the tangent line to find the approximately close value to the function. The equation of the function of the tangent is

L(x) = f(a) + f'(a)(x−a)

The tangent will be a very good approximation to the function's graph and will give the closest value of the function. Let us understand this with an example, we can estimate the value of √9.1 using the linear approximation. Here we have the function: f(x) = y = √x. We will find the value of √9 and using linear approximation, we will find the value of √9.1.

We have f(x) = √x, then f'(x) = 1/(2√x)

Putting a = 9 in L(x) = f(a) + f'(a)(x−a), we get,

L(x) = f(9) + f'(9)(9.1−9)

L(x) = 3 + (1/6)0.1

L(x) ≈ 3.0167.

This value is very close to the actual value of √(9.1)

Hence by using derivatives, we can find the linear approximation of function to get the value near to the function.

To get the given probabilities of the event we can use a spinner with 20 green, 25 blue, 40 yellow, and 15 orange parts.

Probability is a way to gauge how likely or unlikely something is to happen. A number between 0 and 1, where 0 denotes an improbable event and 1 denotes a certain event, is used to convey it. The likelihood of an occurrence may be determined by dividing the positive outcomes by the entire number of possible outcomes. For instance, the likelihood of receiving heads on a fair coin flip is 50% since there is only one positive event (heads) out of two possible possibilities (heads or tails). The general probability calculation formula is:

Number of likely outcomes divided by the total number of possible outcomes is how you calculate an event's probability.

b) The time is 2.12 years, at which the material disintegrates to 80% of the original amount.

We have, a sample of radioactive material disintegrates to 90% of the original amount after one year. The term half-life is defined as the time it takes for one-half of the atoms of a radioactive material to disintegrate. Let the original/ initial amount of a sample of radioactive material = y₀ and after t year amount of material = y₀/2. After one year, amount of sample of radioactive material = 90% of y₀. Now, radioactive decay equation form is y(t) = y₀( 0.90)ᵗ ,

We have to calculate value of t when y = y₀/2.

=> [tex]\frac{ y_0}{2} = y_0( 0.90)^t[/tex]

=> 1/2 = (0.90)ᵗ

Taking natural logarithm both sides

=> ln( 1/2) = ln ( 0.90)ᵗ

=> ln( 1/2) = t ln ( 0.90)

=> t = ln(1/2)/ln(0.90)

=> t = 6.579 ~ 6.58 years

b) Now, we have to determine value of t when material disintegrates to 80% of the original amount. Let t years be required time here. So, 80% of y₀ = y₀ ( 0.90)ᵗ

=> 0.80y₀ = y₀( 0.90)ᵗ

Taking natural logarithm both sides

=> ln( 0.80 ) = ln( 0.90)ᵗ

=> ln( 1/2) = t ln( 0.90)
