The area of the shaded region, to the nearest hundredth can be calculated as approximately: 1,195.71 mm².

The area of the shaded region can be found using the area of circle, which is: Area = πr²

Therefore, area of the shaded region = area of larger circle - area of smaller circle.

Area of larger circle:

radius (r) = 14 + 6.6 = 20.6 mm

Area of larger circle = 3.14 * 20.6² = 1,332.4904 mm²

Area of smaller circle:

radius (r) = 6.6 mm

Area of larger circle = 3.14 * 6.6² = 136.7784 mm²

I did this a year ago but I forgot my work sorry!

The length of the other two sides of triangle B are determined as:

9 cm and 12 cm.

When solving for the length of the side of triangles that are are similar, note that their sides have lengths that are proportional to each other.

Thus, since triangles A and B are similar, it means they will have side corresponding side lengths that are proportional, therefore:

Let x represent the length of the longest side of triangle B and y represent the medium side.

Therefore, we have:

4/6 = 6/y

4y = 36

4y/4 = 36/4

y = 9 cm

The mean score of the test is 7.13.

The median score of the test is 7.

To get mean score, we have to multiply each test score by its corresponding frequency, sum up products and then divide by the total frequency.

Mean score = EF/ n

Mean score = (34 + 41 + 50 + 63 + 73 + 85 + 91 + 106) / (4 + 1 + 0 + 3 + 3 + 5 + 1 + 6)

= (12 + 4 + 0 + 18 + 21 + 40 + 9 + 60) / 23

= 164 / 23

= 7.13

To find the median score, we will arrange the scores in ascending order: [tex]3, 4, 4, 4, 4, 6, 6, 6, 7, 7, 7, 8, 8, 8, 8, 8, 9, 10, 10, 10, 10, 10, 10.[/tex]

1: The required table is described below.

2: The range is (0,36)

3: X-intercepts are (-6,0) and (6,0) and the Y-intercept is (0,36)

A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that can be stretched indefinitely in opposing directions. Two points in a two-dimensional plane determine it.

We are given that,

y = -x² + 36

The equation of the rainbow is represented by the parabola,

Now, we are required to find a linear equation which cuts the graph of the parabola at two points.

Let us consider the equation joining the points (-6,0) and (0,36), given by .

y = 6x + 36

So, the corresponding table for the linear equation is given by,

x            y = 6x + 36

-6                      0

0                       36

1                        42

6                       72

Now, we will answer the questions corresponding the functions.

1. Domain and Range of the rainbow.

Since, the equation of the rainbow is

y = -x² + 36

So, from the figure, we get that,

Domain is the set of all real numbers.

Range is the set {y | y ≤ 36}

Here, domain represents the points which are used to plot the path of the rainbow and range represents the points which are form the rainbow.

Not all points make sense in the range as the parabola is opening downwards having maximum point as (0,36).

2. X and Y-intercepts of the rainbow.

As, the 'x and y-intercepts are the points where the graph of the function cuts x-axis and y-axis respectively i.e. where y=0 and x=0 receptively'.

We see that from the figure below,

X-intercepts are (-6,0) and (6,0) and the Y-intercept is (0,36)

Here, these intercepts represents the point where the parabola intersects the individual axis.

3. Is the linear function positive or negative.

As the linear function is  represented by the upward flight of the drone.

So, the linear function is a positive function.

y = 6x + 36

4. The solution of the system of equations is the intersection points of their graphs.

So, from the figure, we see that the equations intersect at the points (-6,0) and (0,36).

Thus, the solution represents the position when both the drone and rainbow intersect each other.

The total area of the regions between the curves is 389.0 square units

From the question, we have the following parameters that can be used in our computation:

f(x) = x⁴ - 12x³ + 48x²

g(x) = 44x + 105

With the use of graphs, the curves intersect ar

x = -1 and x = 5

So, the area of the regions between the curves is

Area = ∫x⁴ - 12x³ + 48x² - 44x - 105

This gives

Area = ∫x⁴ - 12x³ + 48x² - 44x - 105

Integrate the expression

Area =  x * (x⁴ - 15x³ + 80x² - 110x - 525)/5

Recall that x = -1 and x = 5

So, we have

Area =  (-1) * ((-1)⁴ - 15(-1)³ + 80(-1)² - 110(-1) - 525)/5  - (5) * ((5)⁴ - 15(5)³ + 80(5)² - 110(5) - 525)/5

The probability that Rebecka and Aaron both select a poodle is 0.09 or 9/100.

We have,

There are 3 poodles out of 10 puppies, so the probability that Rebecka selects a poodle is 3/10.

After Rebecka selects a poodle and it is replaced with another poodle, there are still 3 poodles out of 10 puppies.

This means,

The probability that Aaron selects a poodle, given that Rebecka selected a poodle, is also 3/10.

Now,

P(both select a poodle) = P(Rebecka selects a poodle) × P(Aaron selects a poodle | Rebecka selected a poodle)

= (3/10) × (3/10)

The weights of equity, debt, and preferred stock, based on the market value of each component, of Linge burger Cheese Corporation, are as follows:

Firstly, we calculate the market value of each capital component and divide the result by the total market value of the firm.  This process determines the weights of equity, debt, and preferred stock.

The market value of equity is the number of shares outstanding multiplied by the current share price.

Number of shares outstanding = 6.4 million

Market value per share = $54

Common stock beta = 1.08

Market value = $345.6 million (6.4 million × $54)

Number of shares outstanding at $100 par value = 200,000

Market value per share  = $103

Market value = $20.6 million (200,000 × $103)

Number of bonds outstanding, par value $1,000 each = 120,000

Maturity period of bonds = 15 years

Market value per bond = 107 percent of par

Market value of debt = $128.4 million (120,000 × 1.07 × $1,000)

T-bill yields = 2.4%

Corporate tax rate = 22%

Total market value = $494.6 million ($345.6 million + $20.6 million + $128.4 million)

Weight of equity = 0.6987 or 69.87% ($345.6 million ÷ $494.6 million)

Weight of preferred stock = 0.0417 or 4.17% ($20.6 million ÷ $494.6 million)

Given is a blueprint we need to find area that be covered and then the cost of covering the area,

So, we will find the area by splitting the figure into different shapes,

So the area =

Ar(rectangle) + Ar(semicircle) + Ar(triangle) + Ar(square)

= 9×3 + 3.14×2²/2 + 1/2×3×1 + 3³

= 27 + 6.28 + 1.5 + 27

Since 1 unit = 7 ft

So, 1 unit² = 49 ft²

therefore, 61.78 units² = 61.78 × 49 = 3027.22 ft²

Since our budget is $7500

Costing of covering the area = 3027.22 × x = 7500

Point K is located at 3.5 on the number line.

To find point K on the number line, we need to apply the ratio LK to KM, which is 6:3. First, we can simplify this ratio to 2:1.

Next, we will find the total distance between points L and M. The distance LM = 6.5 - (-2.5) = 9 units.

Now, we can divide this distance into 3 equal parts, as per the simplified ratio 2:1. Each part will be 9/3 = 3 units long.

Since LK is 2 parts of the ratio, we will multiply the length of one part (3 units) by 2. LK = 3 * 2 = 6 units.
