THE ONE-EYED JACK MINE INVESTIGATION
The abandoned One-Eyed Jack Mine is about 31 miles off the main road adjacent to the Salmon River Wilderness area. There is only a rutted dirt track left where the access road used to run. It is so steep that when we hiked up it we had to pause every fifty feet or so to catch our breath. It seemed impossible but 3- 5 miles further we found remnants of the old wagons, the mineshaft, and the mill. The gold ore found in this mine was embedded in quartz and prospectors used the mill to grind up the quartz and rinse it with acid in huge shallow vats that were agitated so that the gold would sink to the bottom and the quartz could be washed away.
One arrangement of equipment we noticed included a circular vat about 18 feet in diameter which must have been connected by a huge belt to a smaller circular drive wheel 10 feet in diameter. The distance between the wheel and the vat was 8 feet. The equipment had been partially pre-fabricated then carried up the hill piece by piece to be re-assembled on the spot. Just the belt to connect the vat to the drive wheel would have been a major burden. We wondered how many times they had to carry new ones up to replace it. Calculate the length of belt needed to go around the drive wheel and the vat.

Step-by-step explanation:

5 minutes is the outlier. It sticks out from the rest.

The value of the missing side length x in the right triangle is 15 inches.

Pythagorean theorem states that the "square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides.

It is expressed as;

( hypotenuse )² = ( leg 1 )² + ( leg 2 )²

The image in the diagram is a right triangle:

Hypotenuse = 17 inches

Leg 1 = 8 inches

Leg 2 = x

To solve for x, we use the pythagorean theorem.

( hypotenuse )² = ( leg 1 )² + ( leg 2 )²

( leg 2 )² = ( hypotenuse )² - ( leg 1 )²

( leg 2 )² = ( 17 )² - ( 8 )²

( leg 2 )² = 289 - 64

( leg 2 )² = 225

Take the square roots

Leg 2 = √225

Leg 2 = 15 inches.

Therefore, the value of x is 15 inches.

Answer:

Hope this helps ^^

Step-by-step explanation:

Let's define the variables:

Let's call the cost of a burger "B" (in dollars).

Let's call the cost of a hotdog "H" (in dollars).

Now, we can set up a system of equations based on the given information:

Equation 1: 2B + H = 4.82 (Two burgers and one hotdog cost $4.82)

Equation 2: B + 2H = 3.70 (One burger and two hotdogs cost $3.70)

To solve this system of equations, we can use the method of substitution or elimination.

Using the method of elimination, we can multiply Equation 2 by 2 to eliminate the "B" term:

2(B + 2H) = 2(3.70)

2B + 4H = 7.40

Now, we can subtract Equation 1 from this new equation to eliminate the "2B" term:

(2B + 4H) - (2B + H) = 7.40 - 4.82

2H - H = 2.58

H = 2.58

Therefore, the cost of a hotdog is $2.58.

Labeling the answer: The cost of a hotdog is $2.58.

Okay, let's break this down step-by-step:

In the beginning of BS 2077, Dolma deposited B? 120,000 in her account.

The interest rate is 9% per annum.

So in the first year (BS 2077), she earned 9% of 120,000 = B? 10,800 in interest.

Her principal amount increased to 120,000 + 10,800 = B? 130,800

In BS 2078, she earned 9% of 130,800 = B? 11,772 in interest.

Her principal now was 130,800 + 11,772 = B? 142,572

In BS 2079, she earned 9% of 142,572 = B? 12,781 in interest.

Her principal now was 142,572 + 12,781 = B? 155,353

In the beginning of BS 2080, her total balance was B? 155,353.

She paid 6% of her interest as income tax.

9% of 155,353 is 13,991.

6% of 13,991 is 839.

So her total interest received in BS 2080 after paying tax was 13,991 - 839 = B? 13,152.

Her total amount received in BS 2080 was:

Principal (155,353) + Interest (13,152) = B? 168,505

So the total amount Dolma received in the beginning of BS 2080 was B? 168,505

Find the quotient and remainder using synthetic division.

The remainder is

Answer:

Step-by-step explanation:

To use synthetic division, we need to set up the coefficients of the dividend polynomial in decreasing order of powers of x, including any missing terms with zero coefficients.

So we have:

Dividend: x^4 - 3x^3 + 9x + 6

Divisor: x + 1

We can represent the divisor as (x + 1) and set up the synthetic division table as follows:

-1 | 1 -3 9 0 6

| -1 4 -13 13

|___________________

| 1 -4 13 -13 19

The numbers on the first row of the table are the coefficients of the dividend polynomial in decreasing order of powers of x. The -1 on the left of the table is the opposite of the divisor, x + 1.

The first number in the second row is always 0, and we get it by bringing down the first coefficient, which is 1. To get the next number in the second row, we multiply the divisor, -1, by 1, and add the result to the second coefficient, which is -3. This gives us -1 x -3 = 3, which we write under -3 in the first row.

We repeat this process for the next numbers in the second row, always multiplying the divisor by the last number in the second row, and adding the result to the next coefficient in the first row. We continue until we reach the last coefficient in the first row.

The last number in the second row, 13, is the remainder of the division. The other numbers in the second row are the coefficients of the quotient polynomial in decreasing order of powers of x. So the quotient is:

x^3 - 4x^2 + 13x - 13

And the remainder is:

13

Therefore, the quotient is x^3 - 4x^2 + 13x - 13, and the remainder is 13.

The graph of the translations are attached

The red is the preimage while the blue is the image

The absolute value graph has equation f(x) = |2x| and the translation we want to obtain is y = f(x) + 4 and this is a translation 4 units up

This results to a graph of equation  y = f(x) + 4 = |2x| + 4

For the parabolic graph, the equation is written as

y = a(x - 2)² - 3

solving for a using (0, -5)

-5 = a(0 - 2)² - 3

-2 = 4a

a = -1/2, then the equation is g(x) = -1/2 (x - 2)² - 3

Applying the translation, the equation will be

Answer:

x=58.74

Step-by-step explanation:

4x+5(-42)=25

4x+-210=25

4x=25+210

4x=235

x=235/4

x=58.75

The solutions to the original equation are:

x = π - 3π/2 = -π/2

x = 3π/2 - 3π/2 = 0

So the values of x that satisfy the equation are -π/2 and 0.

To solve the given equation, we can use the following             trigonometric identity:

sin(A) + sin(B) = 2*sin((A+B)/2)*cos((A-B)/2)

Applying this identity to sin(3π/2+x) + sin(3π/2+x), we get:

sin(3π/2+x) + sin(3π/2+x) = 2*sin((3π/2+x + 3π/2+x)/2)cos((3π/2+x - 3π/2+x)/2)

= 2sin(3π/2+x)cos(0)

= 2(-cos(x))

Therefore, the equation can be simplified to:

-2*cos(x) = 2

Dividing both sides by -2, we get:

cos(x) = -1

This means that x is either π or 3π/2, since those are the values where cos(x) = -1.

The end behavior of [tex]g(x) = -3e^x[/tex] is As x approaches positive infinity, g(x) approaches negative infinity, As x approaches negative infinity, g(x) approaches 0.

To determine the end behavior of the function g(x) = -3e^x, we need to consider what happens to the output of the function as x gets very large (approaches positive infinity) or very small (approaches negative infinity).

As x approaches positive infinity, e^x also approaches positive infinity, since e is a positive number greater than 1. Therefore, -3e^x approaches negative infinity as x approaches positive infinity. We can write this as:

lim x → ∞ (-3[tex]e^x[/tex]) = -∞

This means that the function g(x) approaches negative infinity as x approaches positive infinity.

Similarly, as x approaches negative infinity, e^x approaches 0, since e to a negative power is equal to 1 divided by e raised to the absolute value of that power. Therefore, -3e^x approaches 0 as x approaches negative infinity. We can write this as:

lim x → -∞ (-3[tex]e^x[/tex]) = 0

This means that the function g(x) approaches 0 as x approaches negative infinity.

So, in summary, the end behavior of g(x) = -3[tex]e^x[/tex] is:

As x approaches positive infinity, g(x) approaches negative infinity.

As x approaches negative infinity, g(x) approaches 0.

Answer:

17.7 degree

Step-by-step explanation:

We can begin by drawing a diagram:

```

C

/|

/ |

/α | 10.5 mi```

A------β------B

\ /

\ /

\/

8.8 mi

```

We can label angles β and α as shown, where β represents the angle from point C to point B and α```

A ------- 9.2 mi -------- B

```

Let's label some angles in the diagram:

- Angle A: the angle between the line from A to C and the line from A to B

- Angle B: the angle between the line from C to A and the line from C to B

- Angle α: the angle at the buoy C

We want to find the measure of angle α. To do that, we can use the law of cosines to find the length of the side opposite angle α:

```

c^2 = a^2 + b^2 - 2ab cos(C)

```

where a = 8.8, b = 10.5, and C = angle B. We can solve for cos(C):

```

cos(C) = (a^2 + b^2 - c^2) / 2ab

```

Since we know a, b, and c (8.8, 10.5, and 9.2 respectively), we can calculate cos(C):

```

cos(C) = (8.8^2 + 10.5^2 - 9.2^2) / (2 * 8.8 * 10.5) ≈ 0.701

```

Now we can find angle B using the inverse cosine function:

```

B = cos^-1(cos(C)) ≈ 45.4°

```

Finally, we can find angle α by subtracting angle A from angle B:

```

α = B - A ≈ 17.7°

```

So the measure of the turn that the ship has to make at the buoy is approximately 17.7 degrees.

The required perimeter of the equilateral triangle is 12.72 cm.

An equilateral triangle has all three sides equal in length. Therefore, if the edge of an equilateral triangle is 4.24 cm, then all three sides are 4.24 cm.

Perimeter = 4.24 cm + 4.24 cm + 4.24 cm

Perimeter = 12.72 cm
