Step-by-step explanation:

The sketched region enclosed by the given curves, y = 2/x, y = 8x, and y = x/8 is given below.

To sketch the region enclosed by the given curves, we'll first plot each curve separately and then identify the region between them. The curves are:

y = 2/x

y = 8x

y = x/8

Let's start by plotting these curves one by one:

y = 2/x:

Since x > 0, the curve y = 2/x is a hyperbola with the y-axis as an asymptote and passes through the point (1, 2).

y = 8x:

This is a straight line passing through the origin (0, 0) with a slope of 8. The line goes through the first quadrant.

y = x/8:

This is another straight line with a slope of 1/8. It passes through the origin (0, 0) and also goes through the first quadrant.

Therefore, the final graph is given below.

There are \(72^{16\) valid passwords that can be created with the given constraints.

To calculate the total number of valid passwords, we need to consider the number of options for each character in the password.

1. Digits (0-9): There are 10 digits.

2. Uppercase letters (A-Z): There are 26 uppercase letters.

3. Lowercase letters (a-z): There are 26 lowercase letters.

4. Special characters: There are 10 special characters.

In total, there are 10 + 26 + 26 + 10 = 72 possible characters for each position in the password.

Since the password must consist of 16 characters, we have 72 choices for each character. We can calculate the total

number of valid passwords using the formula

Total passwords = (number of choices per character)^(number of characters)

Total passwords = \(72^{16\)

So, there are\(72^{16\) valid passwords that can be created with the given constraints.

The method applied for determining the density of a solid (regular and irregular) and a liquid is based on the concept of mass and volume.

For solids (regular and irregular):

Determining the mass: The mass of the solid can be measured using a balance or scale. The unit of mass is typically grams (g) or kilograms (kg).

Determining the volume:

Regular solids: The volume of regular solids, such as cubes or rectangular prisms, can be calculated using their geometric formulas. For example, the volume of a cube is calculated by cubing the length of one of its sides: Volume = side length^3.

Irregular solids: The volume of irregular solids can be determined using various methods such as water displacement. The solid is immersed in a known volume of liquid (e.g., water), and the increase in the volume of the liquid is measured. This increase represents the volume of the solid.

Calculating the density: The density of a solid is calculated by dividing its mass by its volume. The unit of density is typically grams per cubic centimeter (g/cm^3) or kilograms per cubic meter (kg/m^3).

For liquids:

Determining the mass: Similar to solids, the mass of the liquid can be measured using a balance or scale.

Determining the volume: The volume of a liquid can be measured directly using a graduated cylinder or other volumetric measuring devices. The unit of volume is typically milliliters (mL) or liters (L).

Calculating the density: The density of a liquid is calculated by dividing its mass by its volume. The unit of density is typically grams per milliliter (g/mL) or kilograms per liter (kg/L).

The method for determining the density of a solid (regular and irregular) involves measuring the mass and volume of the solid and calculating the density by dividing the mass by the volume. For liquids, the density is determined similarly by measuring the mass and volume.

Both are correct because after substituting the same value into both expressions, the result is the same. Therefore, the option C is the correct answer.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is 1/6 (6x+12)-1/2 (4x+2)=-x+1.

Here, 1/6 (6x+12)-1/2 (4x+2)=-x+1

Multiply 1/6 into (6x+12), we get 2x+2 and multiply 1/2 into (4x+2), we get 2x+1.

2x+2-(2x+1)= -x+1

2x+2-2x-1=-x+1

2x-2x+2-1=-x+1 (Group the like terms and simplify)

1=-x+1

x=1-1 (Transpose 1 to RHS of the equation and x to the LHS of the equation).

The interest rate for the savings account is 5% after 4 years, $20,000 deposited in a savings account with simple interest earned $800 in interest.

We can use the formula for simple interest to solve the problem:

Simple interest = (Principal * Rate * Time) / 100

where Principal is the initial amount deposited, Rate is the interest rate, and Time is the time period for which the interest is calculated.

We know that the Principal is $20,000 and the time period is 4 years. We are also given that the interest earned is $800. So we can plug in these values and solve for the interest rate:

$800 = (20,000 * Rate * 4) / 100

Multiplying both sides by 100 and dividing by 20,000 * 4, we get:

Rate = $800 / (20,000 * 4 / 100) = 0.05 or 5%

Therefore, the interest rate for the savings account is 5%.

The probability that X is between 57 and 105 is 0.8914.

Given:

* X is normally distributed with mean=90 and standard deviation=12

* P(57 < X < 105)

Solution:

* Convert the given values to z-scores:

   * z = (X - μ) / σ

   * z = (57 - 90) / 12 = -2.50

   * z = (105 - 90) / 12 = 1.25

* Use the z-table to find the probability:

   * P(Z < -2.50) = 0.0062

   * P(Z < 1.25) = 0.8944

* Add the probabilities to find the total probability:

   * P(57 < X < 105) = 0.0062 + 0.8944 = 0.8914

Therefore, the probability that X is between 57 and 105 is 0.8914.

Answer:

The median height of Sam and his brothers is 135.

Step-by-step explanation:

First, let's find the age of Sam's brothers:

\( B_{1} = 140 cm - 5 cm = 135 cm \)

\( B_{2} = 140 cm - 7 cm = 133 cm \)

The median height of Sam and his brothers is given by the middle number of the three values arranged from lowest to highest:

133   135   140                      

Since the middle number is 135, then the median height is 135.

Therefore, the median height of Sam and his brothers is 135.

The measurement of angles are given as  20.92°, 40.83°,  57.76°, 71.17°, 26.21° and 44.7°respectively.

The trigonometric ratios are defined for a right angled triangle.

The example of these ratios are sin, cos, tan, cosec, sec and cot.

The trigonometric ratios are useful in determining the heights and distances of the large objects.

The given problem can be solved by applying the trigonometric ratios to all of the triangle as follows,

(11) In the given triangle,

Sinθ = 5/14

=> θ = Sin⁻¹(5/14) = 20.92°

Tanθ = 7/8.1

=> θ = Tan⁻¹(7/8.1) = 40.83°

(13)  In the given triangle,

Cosθ = 8/15

=> θ = Cos⁻¹(8/15) = 57.76°

(14) In the given triangle,

Tanθ = 8.8/3

=> θ = Tan⁻¹(8.8/3) = 71.17°

(15) In the given triangle,

Tanθ = 6.4/13

=> θ = Tan⁻¹( 6.4/13) = 26.21°

(16) In the given triangle,

Tanθ =9.4/9.5

=> θ = Tan⁻¹( 9.4/9.5) = 44.7°

Hence, the measures of the angles indicated in the triangles are obtained as 20.92°, 40.83°,  57.76°, 71.17°, 26.21° and 44.7°respectively.
