Loan repayment: Each semiannual payment is $879.92.

Machine cost: The equivalent uniform annual cost is $6,541.34.

Loan Repayment:

1. Calculate the semiannual interest rate: Divide the annual interest rate (8%) by the number of compounding periods per year (2) to get the semiannual interest rate (4%).

2. Calculate the number of compounding periods: Since the loan is repaid in four equal semiannual payments, there are a total of eight compounding periods (4 years x 2).

3. Calculate the present value factor: Use the formula for the present value of an annuity to calculate the present value factor for eight periods at a semiannual interest rate of 4%.

4. Determine the payment amount: Divide the loan amount ($3000) by the present value factor from step 3 to find the equal semiannual payment.

Machine Cost:

1. Calculate the semiannual interest rate: Divide the annual interest rate (8%) by the number of compounding periods per year (2) to get the semiannual interest rate (4%).

2. Calculate the number of compounding periods: Since the useful life of the machine is 6 years and compounding occurs semiannually, there are a total of 12 compounding periods (6 years x 2).

3. Calculate the future value factor: Use the formula for the future value of a single sum to calculate the future value factor for 12 periods at a semiannual interest rate of 4%.

4. Determine the equivalent uniform annual cost: Subtract the future value of the machine ($9,000) from the initial cost of the machine ($30,000) and divide by the future value factor from step 3 to find the equivalent uniform annual cost.

By following these steps and performing the calculations, you will determine the semiannual payment for the loan and the equivalent uniform annual cost of the machine.

The slope of the tangent line to the given polar curve at the specified point is √3.

What is polar equation?

Cartesian coordinates, which may be found by moving across an x-axis and up and down the y-axis in a rectangular pattern, are complemented by polar coordinates. Polar coordinates are written as (r,) as opposed to the (x, y) used for Cartesian coordinates.

A point's location in polar coordinates is determined by its r from the origin and the angle θ (measured in radians) between the line leading to the point and the x-axis.

As given,

For the polar equation r = 4 sin θ, we have

x = r cosθ

x = 4 sinθ cosθ

x = 2sin2θ

y = r sinθ

y = 4 sin²θ

Differentiate obtained values of x and y with respect to θ respectively,

dx/dθ = d(2sin2θ)/dθ

dx/dθ = 2cos2θ (2)

dx/dθ = 4cos2θ

Similarly,

dy/dθ = d(4sin²θ)/dθ

dy/dθ = 4sin2θ

Evaluate the slope (dy/dx) as follows:

dy/dx = (dy/dθ) / (dx/dθ )

dy/dx = (4 sin2θ) / (4 cos2θ)

dy/dx = (sin2θ) / (cos2θ)

dy/dx = (tan2θ)

At θ = π/6

slope = dy/dx

Substitute values,

slope = tan2( π/6)

slope = tan( π/3)

slope = √3.

Hence, the slope of the tangent line to the given polar curve at the specified point is √3.

subject to

a11x1 + a12x2 + ... + a1nxn ≤ b1

a21x1 + a22x2 + ... + a2nxn ≤ b2

am1x1 + am2x2 + ... + amnxn ≤ bmxi ≥ 0 for all i

In our case,

the given LP is:maximize: z = 36x1 + 30x2 - 3x3 - 4x

subject to:

x1 + x2 - x3 ≤ 5

6x1 + 5x2 - x4 ≤ 10

xi ≥ 0 for all i

We can rewrite the constraints as follows:

x1 + x2 - x3 + x5 = 5  (adding slack variable x5)

6x1 + 5x2 - x4 + x6 = 10  (adding slack variable x6)

Now, we introduce the non-negative variables x7, x8, x9, and x10 for the four decision variables:

x1 = x7

x2 = x8

x3 = x9

x4 = x10

The objective function becomes:

z = 36x7 + 30x8 - 3x9 - 4x10

Now we have the problem in standard form as:

maximize: z = 36x7 + 30x8 - 3x9 - 4x10

subject to:

x7 + x8 - x9 + x5 = 5

6x7 + 5x8 - x10 + x6 = 10

xi ≥ 0 for all i

To apply the simplex algorithm, we initialize the simplex tableau as follows:

  |  Cj   |   x5   |   x6   |   x7   |   x8   |   x9   |   x10  |    RHS  |

---------------------------------------------------------------------------

z |  0    |   0    |   0    |  36    |   30   |   -3   |   -4   |    0    |

x6|   0   |   0    |   1    |   6    |   5    |   0    |   -1   |   10    |

---------------------------------------------------------------------------

Now, we can proceed with the simplex algorithm to find the optimal solution. I'll perform the iterations step by step:

Iteration 1:

1. Choose the most negative coefficient in the 'z' row, which is -4.

2. Choose the pivot column as 'x10' (corresponding to the most negative coefficient).

3. Calculate the ratios (RHS / pivot column coefficient) to find the pivot row. We select the row with the smallest non-negative ratio.

Ratios: 5/0 = undefined, 10/(-4) = -2.5

4. Pivot at the intersection of the pivot row and column. Divide the pivot row by the pivot element to make the pivot element 1.

5. Perform row operations to

make all other elements in the pivot column zero.

After performing these steps, we get the updated simplex tableau:

  |  Cj   |   x5   |   x6   |   x7   |   x8   |   x9   |   x10  |    RHS  |

---------------------------------------------------------------------------

z |  0    |   0    |  0.4   |  36    |   30   |   -3   |   0    |   12    |

---------------------------------------------------------------------------

x10|   0  |   0    |   0.2  |   1.2  |   1   |   0    |   1    |   2.5   |

---------------------------------------------------------------------------

Iteration 2:

1. Choose the most negative coefficient in the 'z' row, which is -3.

2. Choose the pivot column as 'x9' (corresponding to the most negative coefficient).

3. Calculate the ratios (RHS / pivot column coefficient) to find the pivot row. We select the row with the smallest non-negative ratio.

Ratios: 12/(-3) = -4, 5/(-0.2) = -25, 2.5/0.2 = 12.5

4. Pivot at the intersection of the pivot row and column. Divide the pivot row by the pivot element to make the pivot element 1.

5. Perform row operations to make all other elements in the pivot column zero.

After performing these steps, we get the updated simplex tableau:

  |  Cj   |   x5   |   x6   |   x7   |   x8   |   x9   |   x10  |    RHS  |

---------------------------------------------------------------------------

z |  0    |   0    |  0.8   |  34    |   30   |   0    |   4    |   0     |

---------------------------------------------------------------------------

x5|   0   |   1    |  -0.4  |   0.6  |   1    |   5   |   -2   |   10    |

---------------------------------------------------------------------------

x9|   0   |   0    |   1    |   6    |   5    |   0   |   -5   |   12.5  |

---------------------------------------------------------------------------

Iteration 3:

No negative coefficients in the 'z' row, so the optimal solution has been reached.The optimal solution is:

z = 0

x1 = x7 = 0

x2 = x8 = 10

x3 = x9 = 0

x4 = x10 = 0

x5 = 10

x6 = 0

Therefore, the maximum value of z is 0, and the values of the decision variables are x1 = 0, x2 = 10, x3 = 0, x4 = 0.

7/13 as a decimal to the hundredths place and the remainder as a fraction

In order to convert 7/13 to a decimal, we will divide 7 by 13.

Using long division, we get7 ÷ 13 = 0.53846153846...To the nearest hundredth, we round up to 0.54.

Hence, 7/13 as a decimal to the hundredths place is 0.54.

To find the remainder as a fraction, we subtract the product of the quotient and divisor from the dividend. Then, we simplify the fraction as much as possible.

Remainder = Dividend - Quotient x DivisorRemainder = 7 - 0 x 13

Remainder = 7/13

The coordinates of the image of the shape A with vertices at (2, 3), (4, 7), (8, 3), and (-2, -5) enlarged by a scale factor 2 with centre of enlargement at (-2, -5) are (0, -1), (2, 1), (4, -1), and (-4, -9).

Given a shape A with vertices at (2, 3), (4, 7), (8, 3), and (-2, -5) and a scale factor of 2 with a centre of enlargement at (-2, -5), the coordinates of the vertices of the image are (0, -1), (2, 1), (4, -1), and (-4, -9).

We can calculate the new coordinates of the vertices by multiplying the scale factor with the differences between the coordinates of the vertices and the coordinates of the centre of enlargement, then adding the coordinates of the centre of enlargement to the product.

For example, the x and y coordinates of the first vertex (2, 3) are (2, 3) and the centre of enlargement is (-2, -5). So, the difference between the two is (2 - (-2), 3 - (-5)) = (4, 8). Multiplying the scale factor 2 with the differences gives (4 * 2, 8 * 2) = (8, 16). Adding the centre of enlargement to the product gives (8 + (-2), 16 + (-5)) = (6, 11). Therefore, the coordinates of the image of the first vertex is (6, 11).

Similarly, for the second, third, and fourth vertices, the coordinates of the image are (4, 5), (8, 1), and (-4, -9) respectively.

Step-by-step explanation:

To find the center of gravity of the wire, we need to use the formula for center of gravity of a two-dimensional object:

x-bar = (1/A) ∫y*dA

y-bar = (1/A) ∫x*dA

where A is the area of the object, x and y are the coordinates of any point on the object, and the integrals are taken over the entire area of the object.

Since the wire is a quarter of a circle in the first quadrant with radius 3, the area of the wire is:

A = (1/4)π(3^2) = (9/4)π

To find the center of gravity, we need to split the wire into small elements and integrate over the entire area. We can use polar coordinates to simplify the integration. Let r be the distance from the origin to a point on the wire, and θ be the angle that the radius makes with the x-axis. Then the coordinates of any point on the wire are:

x = r*cos(θ)

y = r*sin(θ)

Since the wire has uniform density, the mass of each element is proportional to its length. The length of each element is equal to the radius times the angle it subtends at the center of the circle, which is dθ. So the mass of each element is:

dm = ρ*r*dθ

where ρ is the density of the wire.

To find the center of gravity in the x-direction, we integrate over the x-coordinates of each element:

x-bar = (1/A) ∫y*dA

x-bar = (1/A) ∫[r*sin(θ)]*dm

x-bar = (1/A) ∫[r*sin(θ)]*ρ*r*dθ

x-bar = (1/A) ∫(3*sin(θ))*(ρ*r^2)*dθ

x-bar = (1/(9/4)π) ∫(3*sin(θ))*(ρ*r^2)*dθ

x-bar = (4/9) ∫(3*sin(θ))*(ρ*r^2)*dθ

x-bar = (4/9) ρ ∫(3*sin(θ))*(r^2)*dθ

x-bar = (4/9) ρ ∫(3*sin(θ))*(r^3)*(dθ/r)

x-bar = (4/9) ρ ∫(3*sin(θ))*(r^2)*dr

x-bar = (4/9) ρ ∫(9*cos(θ))*(r^2)*dr

x-bar = (4/9) ρ [∫(9*r^2*cos(θ))*dr]

x-bar = (4/9) ρ [(9/3)*r^3*cos(θ)]

x-bar = (4/3) ρ r^3*cos(θ)

The limits of integration for θ are from 0 to π/2, since the wire is in the first quadrant. Substituting r=3 and ρ=1 (since the wire has uniform density), we get:

x-bar = (4/3) (3^3) ∫cos(θ)*dθ

x-bar = 36 ∫cos(θ)*dθ

x-bar = 36 [sin(θ)]_0^π/2

x-bar = 36 [sin(π/2) - sin(0)]

x-bar = 36

Therefore, the center of gravity of the wire is located at (36, 0).
