The area of the composite figure is approximately 57.51 square centimeters.

By calculating the area of the triangle and the sector, and then adding them together, we may determine the area of the composite figure.

The following formula can be used to determine the sector's area:

Sector area is equal to (central angle / 360) x r2.

The sector's radius is 8 cm, and its central angle is 60°, resulting in:

Sector area equals (60/360) x 3.14 x 82

Sector size: 33.51

The following formula can be used to get the triangle's area:

Area of triangle Equals base x height x half.

The Pythagorean theorem can be used to determine the triangle's height given that its base is 8 cm:

a² + b² = c²

8² + h² = 10²

64 + h² = 100

h² = 36

h = 6

As a result, given that the triangle's height is 6 cm, we have:

Triangle's area equals 1/2 x 8 x 6.

Triangle has a 24 area.

By combining the areas of the triangle and the sector, we can determine the area of the composite figure.

33.51 + 24 times the composite figure's area

The composite figure's area is 57.51.

Hence, the composite figure has a surface area of roughly 57.51 square centimetres.

Answer:

See below.

Step-by-step explanation:

We are asked to find the measure of ∠CEB.

We already know that the 3 angles combined have a total sum of 163°.

Let's set the 3 angles equal to 163°.

[tex]x-10+4x +2x+5=163[/tex]

Now, we should Combine Like Terms.

Combining Like Terms is adding, or subtracting together 2 or more numbers or variables that are alike.

For example, if we were given the expression;

[tex]5x + 3 - 2x + 9[/tex]

We should combine 5x and 2x, 3 and 9 since they are like terms.

For our equation;

[tex]x-10+4x +2x+5=163[/tex]

We should combine x, 4x, and 2x. We also should combine -10, 5, and 163.

Afterwards, we should have:

[tex]7x=168[/tex]

Simplify:

[tex]x= 24[/tex]

Substitute 24 within the value of x in the given expression for ∠CEB.

Substitute:

[tex]-10 + 4(24) = 86[/tex]

The measure of ∠CEB = 86°

The value of z in the circle is 2.3 units

In the question, the following statements represents the given parameters

2 * (z + 3.6) = 11 4/5

Express as decimal

2 * (z + 3.6) = 11.8

So, we have

z + 3.6 = 5.9

Evaluate the like terms

So the area of the shaded part of the rectangle is 125 square meters.

Area is the measure of the size of a two-dimensional surface or region. It is typically measured in square units, such as square meters or square feet. The area of a shape is the amount of space that it occupies within a defined boundary. The formula for the area of a shape varies depending on the shape, but for common shapes like rectangles, triangles, and circles, there are specific formulas that can be used to calculate the area. Knowing the area of a shape is important for many practical purposes, such as calculating the amount of paint needed to cover a wall or the amount of carpet needed to cover a floor.

Here,

To find the area of the shaded part of the rectangle, we need to subtract the area of the unshaded triangle from the total area of the rectangle. The rectangle has a length of 16 meters and a width of 10 meters, so its total area is:

Area of rectangle = length x width

= 16 m x 10 m

= 160 m²

The unshaded triangle has a base of 9 meters and a height of 10 meters, so its area is:

Area of triangle = 1/2 x base x height

= 1/2 x 7 m x 10 m

= 35 m²

Therefore, the area of the shaded part of the rectangle is:

Area of shaded part = Area of rectangle - Area of triangle

= 160 m² - 35 m²

= 125 m²

The Venn diagram for (D ⋃ E) ⋃ F will be the ovarlapped region of D,E and F.

A Venn diagram is a graphical representation of set theory that uses circles or other closed shapes to show the relationships between sets of objects. In a Venn diagram, each set is represented by a circle or other shape, and the area of the circle represents the total number of objects in that set.

The circles are usually drawn so that they overlap, with the overlapping region representing the objects that belong to both sets. Venn diagrams can be used to illustrate set operations such as union, intersection, and complement.

Now,

As i can not draw here

so i will explain it

To create the Venn diagram, we first draw three overlapping circles to represent the sets D, E, and F. We then shade the regions corresponding to the set operations in the expression, starting from the innermost operation and working our way out.

The expression (D ⋃ E) represents the union of sets D and E, so we shade the region where the circles for D and E overlap. This region represents all the elements that are in D or E or both.

Next, we take the union of (D ⋃ E) with F. This means we shade the region where the circle for F overlaps with the region we shaded in the previous step. This region represents all the elements that are in D or E or F or any combination of these sets.

The final Venn diagram should have three overlapping circles, with the region where all three circles overlap shaded to represent (D ⋃ E) ⋃ F.

The required probability that the mean height of a sample of sixteen men falls between 66 and 68 inches is approximately 0.6827.

We know that the sample size n = 16, the population mean μ = 67 inches, and the population standard deviation σ = 4 inches.

The sampling distribution of the sample mean can be approximated by a normal distribution with mean μ and standard deviation σ/√n.

Thus, the distribution of the sample mean can be expressed as:

[tex]$\bar{X} \sim \mathcal{N}(\mu, \frac{\sigma}{\sqrt{n}})$$[/tex]

Substituting the given values, we have:

[tex]$\bar{X} \sim \mathcal{N}(67, \frac{4}{\sqrt{16}})$$[/tex]

[tex]$\bar{X} \sim \mathcal{N}(67, 1)$$[/tex]

To find the probability that the sample mean falls between 66 and 68 inches, we need to find the z-scores corresponding to these values and calculate the area under the normal curve between these z-scores.

The z-score corresponding to a sample mean of 66 inches is:

[tex]$z = \frac{66 - 67}{1} = -1$$[/tex]

The z-score corresponding to a sample mean of 68 inches is:

[tex]$z = \frac{68 - 67}{1} = 1$$[/tex]

Thus, we need to find the probability that the z-score falls between -1 and 1. Using a standard normal distribution table or calculator, we can find that this probability is approximately 0.6827.

Therefore, the probability that the mean height of a sample of sixteen men falls between 66 and 68 inches is approximately 0.6827.

"The graph of f(x) has exactly two x-intercepts" -  For a linear function whose domain is the set of all real numbers, this assertion cannot be accurate.

Any function with the formula f(x) = mx + b is referred to as linear.

Setting f(x) = 0, we get:

mx + b = 0

Solving for x, we get:

x = -b/m

Depending on the slope m and y-intercept b values, there are an unlimited number of x-intercepts.

A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph. If the function has more variables, they should all be constants or known variables in order for the function to continue to function as a linear function. A linear function is a function that, when plotted, creates a straight line. Typically, it is a polynomial function with a maximum degree of 1 or 0. Nonetheless, calculus and linear algebra are also used to represent linear functions. The function notation is the only distinction. It is also important to understand an ordered pair written in function notation.

from the questions:

A function with the formula f(x) = mx + b, where m and b are constants, is referred to as a linear function. When f(x) = 0, the point where a linear function intersects the x-axis is known as the x-intercept.

Setting f(x) = 0, we get:

mx + b = 0

Solving for x, we get:

x = -b/m

As a result, the x-intercept of a linear function is a single point, (-b/m, 0), and depending on the slope m and y-intercept b values, there may only be zero, one, or infinitely many x-intercepts.

As a result, for a linear function whose domain is the set of all real numbers, it is not possible for the statement "The graph of f(x) has precisely two x-intercepts" to be true.

Part D: the absolute value of -1.8 is the same as the absolute value of 1.8, we have shown that you hiked the same distance in both directions.

It can be measured in various units such as meters, kilometers, feet, miles, etc. In mathematics, the distance between two points in a coordinate plane can be calculated using the distance formula, which is derived from the Pythagorean theorem. The distance formula is:

d = √[(x2 - x1)² + (y2 - y1)²]

Where (x1, y1) and (x2, y2) are the coordinates of the two points and d is the distance between them

Part A: The distance from the top of the waterfall to the place where you eat lunch is 1.3 miles, so the drone would need to fly up 1.3 miles

Part B: The distance from the top of the waterfall to the place where you go swimming is 1.8 miles, so the drone would need to fly up 1.8 miles

Part C: In this problem, the value of zero represents the top of the waterfall where you and your friend are currently located.

Part D: Let x be the distance you hiked to go swimming, and let y be the distance you hiked to go back to the top to meet your friend. Then, the total distance you hiked is the sum of the absolute values of x and y, which can be written as |x| + |y|. Since you hiked down 1.8 miles to go swimming and then hiked back up 1.8 miles to the top, x = -1.8 and y = 1.8. Substituting these values, we get |(-1.8)| + |1.8| = 1.8 + 1.8 = 3.6. Since the absolute value of -1.8 is the same as the absolute value of 1.8, we have shown that you hiked the same distance in both directions.

Answer:

Step-by-step explanation:

The trigonometric function that does not have a period of 2π is the tangent function, denoted by tan(x).

The period of a trigonometric function is the length of one complete cycle of the function. For the sine and cosine functions, the period is always 2π, which means that the function repeats itself every 2π units.

However, the tangent function has a period of π, which means that it repeats itself every π units. This is because the tangent function has vertical asymptotes at x = (n + 1/2)π, where n is an integer, and the function changes sign between these asymptotes. Therefore, the tangent function does not have a period of 2π.

What is a good example of a line's slope?

The proportion of the increase in the y-value to the increase in the x-value may also be used to determine slope. For instance: We can get the slope of a line given two locations, P = (0, -1) & Q = (4,1) on the line.

A. Since the line's slope is 2, it follows that the y-variable, which is most likely distance, grows by 2 units for every increment in the x-variable, which is most likely time. The accurate statement is thus: speed is increased by Two miles per hour.

B. Since the line's slope is 2, it follows that the y-variable will drop by 2 units for every unit rise in the x-variable, which is most likely time. The accurate description is thus: speed drops by Two miles per hour.

C. If the line's slope is 1/2, the y-variable will rise by 1/2 unit for every increment in the x-variable, which is probably time. The precise description is that the distance grows by a mile every two hours.

D. If indeed the line's slope is 1/2, the y-variable will drop by 1/2 unit for every unit rise in the x-variable, which is probably time. The precise description is: distance shrinks by a mile every two hours.
