The amount that the jeweler would charge Mrs. Luisa, given the prices of the successive jewelry would be $ 19, 680

The charge for repairing the jewelry pieces is calculated in a geometric progression:

= 6, 63, 63 ², 63 ³, ..., 63 ⁷

The sum of the first n terms in such a progression is:

S = a x (r ⁿ - 1) / ( r - 1 )

Seeing as there are 8 pieces of jewelry, the total cost to Mrs. Luisa would be:

S = 6 x ( 3 ⁸  - 1) / ( 3 - 1 )

S = 6 x ( 6561 - 1 ) / 2

S = 6 x 6560 / 2

S = 3 x 6560

S = $ 19, 680

The solution is, $85,500 are the total cost savings for Leather Stuff.

Explanation:

In this case, we need to calculate the saving per zipper which is external price minus agreed transfer price.

Then, we will multiply the saving per zipper by the quantity of zipper required by Leather Stuff, which is 90,000 zippers.

Cost saving per zipper

= External price - Agreed transfer price

= $3.50 - $3.25

= $0.25

Total cost saving

= $0.95 x 90,000 zippers

= $85,500

complete question:

Quinn Inc. has a number of divisions. One division, Style, makes zippers that are used in the manufacture of boots. Another division, LeatherStuff, makes boots that use the zippers and needs 90,000 zippers per year. Style incurs the following costs for one zipper: Direct materials $0.23 Direct labor 0.20 Variable overhead 0.95 Fixed overhead 1.32 Total $2.70 Quinn has capacity to make 950,000 zippers per year, but due to a soft market, only plans to produce and sell 620,000 zippers next year. LeatherStuff currently buys zippers from an outside supplier for $3.50 each (the same price that Style receives). Assume that Style and LeatherStuff have agreed on a transfer price of $3.25. What are the total cost savings for LeatherStuff?

Answer: To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A is the final amount

P is the initial principal (the amount borrowed)

r is the annual interest rate (as a decimal)

n is the number of times the interest is compounded per year

t is the time period in years

In this case, we have:

P = $21,000

r = 8.75% = 0.0875

n = 1 (interest is compounded annually)

t = 13 years

So, plugging these values into the formula, we get:

A = 21,000(1 + 0.0875/1)^(1*13)

A = 21,000(1.0875)^13

A = $58,150.51

Therefore, if the loan is paid in full at the end of the 13-year period, $58,150.51 must be paid back, which includes the original principal plus the interest accrued over the 13-year period.

The derivative of the function is f' ( x ) = 9 / ( 4 + 3x ) ( ln 2 )

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = log₂ ( 3x + 4 )³

On simplifying , we get

On taking the derivative of the function , we get

f' ( x ) = d/dx ( log₂ ( 3x + 4 )³ )

Answer:

La suma de los cuatro ángulos de un cuadrilátero es igual a 360 grados. Entonces, si dos ángulos miden 60° y 80°, la suma de esos ángulos es de 140 grados.

Los otros dos ángulos están en una proporción de 2:9, lo que significa que la suma de sus medidas es de 11 partes. Si representamos las medidas de estos ángulos como 2x y 9x, respectivamente, entonces podemos escribir la ecuación:

2x + 9x = 11 partes

11x = 11 partes

x = 1 parte

Por lo tanto, el ángulo más pequeño mide 2x = 2 partes o 2 × 1 = 2 grados, y el ángulo más grande mide 9x = 9 partes o 9 × 1 = 9 grados.

En resumen, los dos ángulos faltantes miden 2° y 9°.

Step-by-step explanation:

The angles in the circle are as follows:

The central angle of an arc is the central angle subtended by the arc.

The measure of an arc is the measure of its central angle.Therefore,mBC = 107 degrees

The angle subtended by an arc at the center is twice the angle subtended at the circumference.

Therefore, m∠BAC = 107 / 2 = 53.5 degrees

The inscribed angle is half the intercepted arc angle.

Therefore, to find mBC, we solve:

46 = 1 / 2

Next, we cross multiply mBC  = 46 × 2

Therefore, mBC = 92 degrees

It can be seen that x = (3 ± √(9 + 32√3)) / 8, which can be expressed in surd form as (3 + √(9 + 32√3)) / 8 or (3 - √(9 + 32√3)) / 8.

To find x using the sine rule, we need to solve the equation:

sine(45) / x = sine(30) / (2x + 2√3)

Simplifying this equation, we have:

(2x - 1) / x = 1 / (2x + 2√3)

Cross-multiplying and simplifying further, we get:

(2x - 1)(2x + 2√3) = x

Expanding the brackets, we have:

[tex]4x^2 + 4\sqrt3x - 2x - 2\sqrt3 = x[/tex]

Rearranging the terms and simplifying, we get:

[tex]4x^2 - 3x - 2\sqrt3 = 0[/tex]

Using the quadratic formula, we can solve for x:

x = (-(-3) ± √((-3)^2 - 4(4)(-2√3))) / (2(4))

x = (3 ± √(9 + 32√3)) / 8

Therefore, x = (3 ± √(9 + 32√3)) / 8, which can be expressed in surd form as (3 + √(9 + 32√3)) / 8 or (3 - √(9 + 32√3)) / 8.

There are 58 Adventure Scouts slept outside on the camping trip.

Let's denote the number of scouts who slept in a cabin, tent, and outside as c, t, and o, respectively. We know that the total number of scouts is 115, so:

c + t + o = 115

We also know that twice as many scouts slept in a cabin as slept in a tent, so:

c = 2t

And we know that the same number of scouts slept outside as slept in a cabin, so:

o = c

We can use these equations to solve for the number of scouts who slept outside:

c + t + o = 115

2t + t + t = 115 (substituting c = 2t and o = c)

4t = 115

t ≈ 28.75

Since we can't have a fractional number of scouts, we need to round this up or down. However, we also know that the number of scouts who slept outside is the same as the number who slept in a cabin, which means that either c or o must be even (since c is twice t). Therefore, we'll round t up to 29 and use that to solve for c and o:

c = 2t ≈ 58

o = c ≈ 58

So, we can conclude that 58 Adventure Scouts slept outside on the camping trip.

The vertex is at (1, 4).

The vertex is at (-1, -4).

The axis of symmetry is x = 1.

The axis of symmetry is x = -1.

The x-intercepts are (3, 0) and (-1, 0).

The x-intercepts are approximately (-2.3, 0) and (0.3, 0).

The y-intercept is (0, 3).

The y-intercept is (0, -6).

We have,

To solve the equations using the quadratic formula, we need to rewrite them in the standard form ax² + bx + c = 0.

-x² + 2x + 3 = 0 can be rewritten as -1x² + 2x + 3 = 0

Here, a = -1, b = 2, and c = 3

Using the quadratic formula, we have:

x = (-b ± √(b² - 4ac)) / 2a

x = (-2 ± √(2² - 4(-1)(3))) / 2(-1)

x = (-2 ± √(16)) / -2

x = 1 ± 2

So, x = 3 or x = -1

2x² + 4x - 6 = 0 is already in the standard form with a = 2, b = 4, and c = -6

Using the quadratic formula, we have:

x = (-4 ± √(4² - 4(2)(-6))) / 2(2)

x = (-4 ± √(52)) / 4

x = (-2 ± √(13)) / 2

To find the vertex of each parabola, we can use the formula x = -b / 2a and then substitute the value of x into the equation to find y.

For -x² + 2x + 3 = 0

We have a = -1 and b = 2, so the vertex is at

x = -b / 2a = -2 / (2(-1)) = 1.

Substitute x = 1 into the equation to find y:

y = -1(1)² + 2(1) + 3 = 4.

So the vertex is at (1, 4).

For 2x² + 4x - 6 = 0,

We have a = 2 and b = 4, so the vertex is at x = -b / 2a = -4 / (2(2)) = -1. Substitute x = -1 into the equation to find y: y = 2(-1)² + 4(-1) - 6 = -4.

So the vertex is at (-1, -4).

The axis of symmetry is a vertical line that passes through the vertex.

For -x² + 2x + 3 = 0, the axis of symmetry is x = 1.

For 2x² + 4x - 6 = 0, the axis of symmetry is x = -1.

To find the x-intercepts, we can set y = 0 in each equation and solve for x using the quadratic formula.

For -x² + 2x + 3 = 0, we have:

x = (-2 ± √(2² - 4(-1)(3))) / 2(-1)

x = (-2 ± √(16)) / -2

x = 1 ± 2

So the x-intercepts are (3, 0) and (-1, 0).

For 2x² + 4x - 6 = 0, we have:

x = (-4 ± √(4² - 4(2)(-6))) / 2(2)

x = (-4 ± √(52)) / 4

x = (-2 ± √(13)) / 2

So the x-intercepts are approximately (-2.3, 0) and (0.3, 0).

To find the y-intercept, we need to set x = 0 and solve for y.

Setting x = 0 in -x² + 2x + 3 = 0.

-0 + 0 + 3 = 3

Therefore, the y-intercept is (0, 3).

Setting x=0 in 2x² + 4x - 6.

2(0)² + 4(0) - 6 = -6

Therefore, the y-intercept is (0, -6).

Thus,

The vertex is at (1, 4).

The vertex is at (-1, -4).

The axis of symmetry is x = 1.

The axis of symmetry is x = -1.

The x-intercepts are (3, 0) and (-1, 0).

The x-intercepts are approximately (-2.3, 0) and (0.3, 0).

The y-intercept is (0, 3).
