Answer:

146 m²

Area of triangle:

Area of upper rectangle:

Area of bottom rectangle:

Total area:

Answer:

146 m²

Step-by-step explanation:

Divide the figure into a triangle and 2 rectangles (see attached diagram)

Formulae

Triangle 1

⇒ area = 1/2 x 16 x (6 + 9 - 4 - 4)

            = 1/2 x 16 x 7

            = 56 m²

Rectangle 2

⇒ area = 3 x (6 + 9)

            = 3 x 15

            = 45 m²

Rectangle 3

⇒ area = 5 x 9

            = 45 m²

Total area

⇒ Total area = triangle 1 + rectangle 2 + rectangle 3

                      = 56 + 45 + 45

                      = 146 m²

A structural break occurs when we see A. an unexpected shift in time-series data.

It is the change in a time series's data-generating mechanism, it is a phenomenon that occurs when a significant event or structural shift in the economy alters the underlying data-generating mechanism. A structural break can happen for several reasons, including natural catastrophes, changes in economic policy, new inventions, and other reasons that alter the way the data is generated.

In the presence of a structural break, we can't assume that the relationships between variables before and after the break are the same. The primary objective of identifying structural breaks in the time-series is to detect changes in the behavior of the series over time, such as changes in the variance of the series, changes in the mean of the series, and changes in the covariance of the series. So therefore the correct answer is A. an unexpected shift in time-series data, the structural break occurs.

The solution to the equation 3cos(4θ) = -2 in the interval from 0 to 2π is θ ≈ 0.2955 (rounded to the nearest hundredth).

To solve the equation 3cos(4θ) = -2 in the interval from 0 to 2π, we can follow these steps:

Divide both sides of the equation by 3 to isolate the cosine term:

cos(4θ) = -2/3

Take the inverse cosine (cos^(-1)) of both sides to eliminate the cosine function:

4θ = cos^(-1)(-2/3)

To solve for θ, divide both sides by 4:

θ = (1/4) * cos^(-1)(-2/3)

Using a calculator, we can evaluate the inverse cosine of -2/3 and divide it by 4 to find the approximate value of θ in the interval from 0 to 2π.

θ ≈ 0.2955

Therefore, the solution to the equation 3cos(4θ) = -2 in the interval from 0 to 2π is θ ≈ 0.2955 (rounded to the nearest hundredth).

The expression that represents the depth reached by the sea lion, relative to the sea level is the option;

An expression consists of a combination of variables and numbers that are arranged according to the rules with which the operators joining the variables and numbers operate.

The depth reached by the seal = 25 feet

The depth of the seal in relation to the sea level = -25 feet

The depth reached by the sea lion to catch a larger fish = 10 feet less than three times as deep as the seal.

Three times as deep as reached by the seal = 3 × -25 = -75 feet

10 feet less than three times as deep as reached by the seal = -75 feet + 10 feet = -65 feet

The probability that a random sample of 4 of the articles will contain a defective article is approximately 0.2916, or about 29.16%.

To find the probability that a random sample of 4 articles will contain a certain number of defective articles, we can use the binomial probability formula:

P(X = k) = (nCk) * (p^k) * (1-p)^(n-k)

where:
- n is the total number of articles in the sample (4 in this case)
- k is the number of defective articles we want to find the probability for
- p is the probability of an article being defective (1/10)
- 1-p is the probability of an article not being defective (9/10)
- nCk represents the number of combinations of n items taken k at a time

It appears that you haven't mentioned the specific number of defective articles you want in the sample of 4. However, you can use the formula above and plug in the values for k (0, 1, 2, 3, or 4) to find the probability for any desired number of defective articles in the sample.

Step-by-step explanation:

There are 0.538 moles of oxygen gas in 17.23 g of oxygen gas.

Given: Mass of oxygen gas = 17.23 g

Now, we have to calculate the moles of oxygen gas in 17.23 g.

We can use the formula below to calculate the same; Number of moles = Mass of substance/Molecular mass of substance

Since the substance is oxygen gas, we can use the molecular formula, O₂

Molecular mass of O₂ = 2 × Atomic mass of oxygen

= 2 × 16

= 32 g/mol

Using the above values in the formula:

Number of moles = 17.23 g/32 g/mol

= 0.538 moles

Therefore, there are 0.538 moles of oxygen gas in 17.23 g of oxygen gas.

The statement is true. If we take any two distinct prime numbers, and the number "1", these numbers will always be pairwise relatively prime.

Two numbers are said to be pairwise relatively prime if their greatest common divisor (GCD) is equal to 1. In this case, since we are considering distinct prime numbers, their GCD will always be 1 since prime numbers have no common factors other than 1 and themselves. Therefore, any two distinct prime numbers will be relatively prime.

Similarly, when we consider the number "1", it is relatively prime to any other number because its only divisor is 1. Hence, when "1" is paired with any prime number, the GCD will be 1.

In summary, whether we consider two distinct prime numbers or pair them with the number "1", the resulting numbers will always be pairwise relatively prime.

Answer: 2000

Step-by-step explanation:

Percentage supporting home team = 65%

Percentage supporting visiting team = 35%

Number of people supporting home team = 1300

Let the total number of people attending the game be represented by x.

Therefore, 65% of x = 1300

65/100 × x = 1300

0.65 × x = 1300

0.65x = 1300

x = 1300 / 0.65

x = 2000

Therefore 2000 people attended the game.

What is Trigonometric Functions?

Trigonometry uses six fundamental trigonometric operations. Trigonometric ratios describe these operations. The sine function, cosine function, secant function, co-secant function, tangent function, and co-tangent function are the six fundamental trigonometric functions. The ratio of sides of a right-angled triangle is the basis for trigonometric functions and identities. Using trigonometric formulas, the sine, cosine, tangent, secant, and cotangent values are calculated for the perpendicular side, hypotenuse, and base of a right triangle.

F(x) = 1 + cos(1/X)

Let's use the angle addition postulate to find the value of m(BAD) + m(DAC):

The angle addition postulate states that if you have an angle formed by two rays, say ∠BAD, and  another angle formed by two rays, say ∠DAC, then the sum of their measures is equal to the measure of the angle formed by the original rays extended to meet the rays of the second angle.

Step-by-step explanation:

To find the new coordinates of the points after Louis multiplied each x-coordinate and y-coordinate of triangle ABC by -2, we can use the following formulas:

New x-coordinate = -2 * old x-coordinate

New y-coordinate = -2 * old y-coordinate

Let's apply these formulas to each point in triangle ABC:

Point A: (-3, 4)

New x-coordinate of A = -2 * (-3) = 6

New y-coordinate of A = -2 * 4 = -8

New coordinates of A: (6, -8)

Point B: (1, 1)

New x-coordinate of B = -2 * 1 = -2

New y-coordinate of B = -2 * 1 = -2

New coordinates of B: (-2, -2)

Point C: (5, -2)

New x-coordinate of C = -2 * 5 = -10

New y-coordinate of C = -2 * (-2) = 4

New coordinates of C: (-10, 4)

Therefore, the new coordinates of the points after Louis multiplied each x-coordinate and y-coordinate of triangle ABC by -2 are:

A: (6, -8)

B: (-2, -2)

C: (-10, 4)
