A regular hexagon can be divided into six equilateral triangles by drawing lines from the center of the hexagon to each of its vertices.

Each of these equilateral triangles has an area that is one-sixth of the total area of the regular hexagon.

When the midpoints of the sides of the regular hexagon are joined to form a smaller regular hexagon, it can be seen that the smaller hexagon is made up of six equilateral triangles, each of which has half the area of the equilateral triangles in the larger hexagon. This is because the sides of the smaller hexagon are half the length of the sides of the larger hexagon.

Therefore, the fraction of the area of the larger hexagon that is enclosed by the smaller hexagon is:

\(6 * (1/2)^2 = 6 * 1/4 = 3/2\)

This means that the smaller hexagon encloses 3/2 of the area of the larger hexagon.

Step-by-step explanation:

Thus, the area of the region inside the polar curve r = 2cos(θ) is given by 2 [(b + (1/2)sin(2b)) - (a + (1/2)sin(2a))].

The area of the region inside the polar curve r = 2cos(θ) can be found using the formula for the area enclosed by a polar curve:

A = (1/2) ∫[a, b] (r(θ))^2 dθ

In this case, we have r(θ) = 2cos(θ). Therefore, substituting r(θ) into the formula, we get:

A = (1/2) ∫[a, b] (2cos(θ))^2 dθ

Simplifying further:

A = (1/2) ∫[a, b] 4cos^2(θ) dθ

Using the trigonometric identity cos^2(θ) = (1 + cos(2θ))/2, we can rewrite the integral:

A = (1/2) ∫[a, b] 4(1 + cos(2θ))/2 dθ

A = 2 ∫[a, b] (1 + cos(2θ)) dθ

Integrating term by term:

A = 2 [θ + (1/2)sin(2θ)] [a, b]

Evaluating the integral limits:

A = 2 [(b + (1/2)sin(2b)) - (a + (1/2)sin(2a))]

In an introductory engineering course with a total of 420 students, the number of boys can be calculated using the given ratio. There are approximately 270 boys in the course.

According to the given ratio of nine boys to every five girls, we can calculate the number of boys in the course.

To find the number of boys, we need to determine the proportion of boys in the total student population. The total number of students is 420, and the ratio of boys to girls is 9:5.

First, we calculate the total number of parts in the ratio: 9 + 5 = 14 parts.

To find the number of boys, we divide the total number of students by the total number of parts in the ratio and multiply it by the number of parts representing boys: (9/14) * 420 ≈ 270.

Therefore, there are approximately 270 boys in the introductory engineering course.

For confidence interval: support of the association rule A to B is 0.5 and the confidence of the association rule A to B is 0.5.

For Support and confidence of the association rule A - B

To determine the support and the confidence of the association rule A → B, where A = {1, }, B = {1}, we use the formulas given below:

Support(A → B) = frequency of (A, B) / N

Confidence(A → B) = frequency of (A, B) / frequency of A

where N is the number of transactions in the database.

To find the frequency of (A, B) and the frequency of A.

Thus Frequency of (A, B) = 1

Since there is only one transaction in the database where both A and B occur, the frequency of (A, B) is 1.

Step-by-step explanation:

The value of the trigonometric expression sin(20) + tan(10) - 6 is  -5.4817.

To find the value of sin20 + tan10 - 6, we will need to calculate the individual trigonometric values and then perform the addition and subtraction.

1. Start by finding the value of sin(20).

Since we are working in degrees, we can use a scientific calculator to determine the sine of 20 degrees: sin(20) ≈ 0.3420.

2. Next, find the value of tan(10).

Similarly, using a calculator, we can determine the tangent of 10 degrees: tan(10) ≈ 0.1763.

3. Now, we can substitute the calculated values into the expression and perform the arithmetic:

sin(20) + tan(10) - 6 ≈ 0.3420 + 0.1763 - 6 ≈ -5.4817

The key assumption for performing Analysis of Variance (ANOVA) is: All of the population variances are equal.

ANOVA is a statistical technique used to compare the means of two or more groups to determine if there are significant differences between them. The key assumption of ANOVA is known as the homogeneity of variances assumption, which states that the population variances across all groups being compared are equal. This assumption is necessary for valid interpretation of the ANOVA results.
When the population variances are equal, it suggests that the variability within each group is similar. This allows for a fair comparison of the group means and increases the validity of the statistical tests performed in ANOVA, such as the F-test.

The centroid of the region bounded by the curves y = 12x and y = √x is (72,1.88).

To find the centroid of the region bounded by the given curves y = 12x and y = √x, the following steps should be followed.

Step 1: Sketch the region bounded by the two curves to have an idea of what the region looks like.

Step 2: Determine the area of the region bounded by the two curves. The area A can be computed by evaluating the definite integral of the difference between the two functions. \(\[\int\limits_{0}^{144} (\sqrt{x}-12x)dx\]\)  We solve for this integral below.\(\[\int\limits_{0}^{144} (\sqrt{x}-12x)dx = 64 - 1728 + \frac{2}{3}\sqrt{6}\] \[\int\limits_{0}^{144} (\sqrt{x}-12x)dx = -1663.30\]\)

Step 3: To find the centroid of the region, we need to determine the x and y coordinates of the centroid. The x-coordinate of the centroid is given by the formula below.

\(\[x = \frac{1}{A}\int\limits_{a}^{b} \frac{1}{2}(y_1^2-y_2^2)dx\]\)

where A is the area of the region, and y1 and y2 are the upper and lower functions, respectively. Substituting values, we obtain

\(\[x = \frac{1}{-1663.30}\int\limits_{0}^{144} \frac{1}{2}((\sqrt{x})^2-(12x)^2)dx\]  \[x = 72\]\)

 The y-coordinate of the centroid is given by the formula below.

\(\[y = \frac{1}{2A}\int\limits_{a}^{b}(y_1+y_2)\sqrt{(y_1-y_2)^2+4dx}\]\)

 Substituting values, we obtain \(\[y = \frac{1}{2(-1663.30)}\int\limits_{0}^{144}(12x+\sqrt{x})\sqrt{(\sqrt{x}-12x)^2+4dx}\]  \[y = 1.88\]\)

Step-by-step explanation:

Relative humidity tends to be highest during the early morning hours, shortly before sunrise.

To determine the Wet-Bulb Temperature (WBT) and Wet-Bulb Depression (WBD), we need the dry-bulb temperature (DBT) and relative humidity (RH) values.

The Wet-Bulb Temperature (WBT) is the lowest temperature that can be achieved by evaporating water into the air at constant pressure, while the Wet-Bulb Depression (WBD) is the difference between the dry-bulb temperature (DBT) and the wet-bulb temperature (WBT). These values are useful in determining the potential for evaporative cooling and assessing heat stress conditions.

Day 1: Air Temperature= 86°F and RH= 60%

To calculate the WBT and WBD for Day 1, we would need additional information such as the barometric pressure or the dew point temperature. Without these values, we cannot determine the specific WBT or WBD for this day.

Day 2: Air Temperature= 41°F and RH= 90%

Similarly, without the necessary additional information, we cannot calculate the WBT or WBD for Day 2.

Regarding your question about the point during the day with the lowest and highest outside relative humidity values, it is generally observed that the relative humidity tends to be highest during the early morning hours, shortly before sunrise. This is because the air temperature often reaches its lowest point overnight, and as the air cools, its capacity to hold moisture decreases, leading to higher relative humidity values.

Conversely, the outside relative humidity tends to be lowest during the late afternoon, typically around the hottest time of the day. As the air temperature rises, its capacity to hold moisture increases, resulting in lower relative humidity values.

It's important to note that these patterns can vary depending on the local climate, weather conditions, and geographical location. Other factors such as wind patterns and nearby bodies of water can also influence relative humidity throughout the day.

The value of the line integral ∮C (2y - e sin(x))dx + (9x - sin(y^3 + y))dy over the circle C of radius 7 centered at (5,2) is 630π.

To evaluate the line integral ∮C (2y - e sin(x))dx + (9x - sin(y^3 + y))dy, where C is a circle of radius 7 centered at the point (5,2)

we can parameterize the circle and then compute the integral using the parameterization.

Let's use the parameterization:

x = 5 + 7cos(t)

y = 2 + 7sin(t)

where t ranges from 0 to 2π to cover the entire circle.

Now, we can calculate the differentials dx and dy in terms of dt:

dx = -7sin(t) dt

dy = 7cos(t) dt

Substituting these differentials and the parameterization into the line integral expression, we have:

∮C (2y - e sin(x))dx + (9x - sin(y^3 + y))dy

= ∮[0, 2π] (2(2 + 7sin(t)) - e sin(5 + 7cos(t))) (-7sin(t) dt) + (9(5 + 7cos(t)) - sin((2 + 7sin(t))^3 + (2 + 7sin(t)))) (7cos(t) dt)

Simplifying, we get:

= -14∮[0, 2π] sin(t)(2 + 7sin(t)) dt + 63∮[0, 2π] cos(t)(5 + 7cos(t)) dt

Integrating term by term, we have:

= -14∫[0, 2π] (2sin(t) + 7sin^2(t)) dt + 63∫[0, 2π] (5cos(t) + 7cos^2(t)) dt

Evaluating the integrals, we find:

= -14(0) + 63(10π) = 630π

Therefore, the value of the line integral ∮C (2y - e sin(x))dx + (9x - sin(y^3 + y))dy over the circle C of radius 7 centered at (5,2) is 630π.

Let x be the first term in the geometric sequence. Then the next two terms in the sequence are xr and xr ², where r is some constant. (This is the defining characteristic of geometric sequences.)

The sum of the first three terms is 42, so

x + xr + xr ² = 42

x (1 + r + r ²) = 42

The third term is 3.2 times the sum of the other two, so that

xr ² = 3.2 (x + xr )

Solve the second equation for r :

xr ² = 3.2 x (1 + r )

We can divide both sides by x since x ≠ 0. (This is obvious, since if x was zero, then all three terms in the sequence would be 0.)

r ² = 3.2 (1 + r )

r ² = 3.2 + 3.2r

r ² - 3.2r - 3.2 = 0

r ² - 16/5 r - 16/5 = 0

5r ² - 16r - 16 = 0

(5r + 4) (r - 4) = 0

==>   r = -4/5 or r = 4

Since there are two possible values of r that might work, there are two possible sequences that meet the criteria.

Plug either of these solutions into the first equation:

r = -4/5   ==>   x (1 + (-4/5) + (-4/5)²) = 42

… … … … … …   21/25 x = 42

… … … … … …   x = 50

r = 4   ==>   x (1 + 4 + 4²) = 42

… … … … …  21x = 42

… … … … …  x = 2

Then the two possible answers would be

• if r = -4/5, then the three terms are {50, -40, 32}

• if r = 4, then they are {2, 8, 32}

Answer:

Step-by-step explanation:

A geometric series means that we multiply one number by a common ratio to get the second number. Let's say our first number is x, and our common ratio is y. We can write the first term is x, and to get the second number, we multiply x by our common ratio, y. For example, if 5 was the first number and 2 was the common ratio, the second number would be 5*2 = 10, and the third would be 10 * 2 = 20.

For our question, the first number is x, the second is x*y, and the third is x*y*y = x*y²

The sum of these three terms is 42, so we can say

x + x*y + x*y² = 42

Next, the third term is equal to 3.2 times the sum of the other two. First, we have 3.2 times something. That something is the sum of the other two, so we must prioritize calculating the sum of the first two numbers, and then multiply that by 3.2 to get the third. We can write this as

(x + x*y) * 3.2 = x*y²

factor out x

x * 3.2(1 +y) = x*y²

divide both sides by x

3.2(1+y) = y²

expand

3.2 + 3.2y = y²

subtract (3.2 + 3.2y) from both sides to make this a quadratic equation

y²-3.2y-3.2 = 0

use the quadratic formula to solve for y  (note that +- here stands for "plus or minus")

\(y = \frac{-(-3.2) +- \sqrt{3.2^{2}-4(-3.2)(1)} }{2} \\= \frac{3.2+-\sqrt{10.24+12.8} }{2} \\= \frac{3.2+- 4.8}{2}\)

=  -0.8 or 4

With these two possibilities, we can try each in our other equation to see what works.

x + x*y + x*y² = 42

for y = -0.8

x + -0.8x + 0.64x = 42

x - 0.16x = 42

0.84x = 42

multiply both sides by 1/0.84 to isolate the x

x=50

This works, with x (the first number) =50, the second number being 50 * -0.8 = -40, and the third being -40 * -0.8 = 32. 50+(-40) = 10, 10*3.2=32, and 50-40+32 = 42

Next, for y=4, we have

x+4x + 16x= 42

21x = 42

divide both sides by 21 to isolate the x

This works as well, with x=2, the second value being 2*4 = 8, and the third value being 8*4 =32. 2+8=10, 10*3.2 = 32, and 2+8+32 = 42
