Step-by-step explanation:

the average rate of change of f(x) in the closed interval [ a, b ] is

\(\frac{f(b)-f(a)}{b-a}\)

here [ a, b ] = [3, 6 ] , then

f(b) = f(6) = \(3^{6}\) + 17 = 729 + 17 = 746

f(a) = f(3) = 3³ + 17 = 27 + 17 = 44 , then

average rate of change = \(\frac{746-44}{6-3}\) = \(\frac{702}{3}\) = 234

The average value of the function f(x) = (x + 2) on the interval [0, 3] is 7/2.

Calculate the definite integral of the function over the interval [a, b], then divide it by the interval's length (b - a), in order to determine the average value of a function f(x) over the interval.

Given that the interval is [0, 3] and the function f(x) = (x + 2), we have:

= (1/3) × [1/2 x² + 2x] evaluated from x=0 to x=3

= (1/3) × [(1/2 × 3² + 2×3) - (1/20² + 20)]

= (1/3) × [(9/2 + 6) - 0]

= (1/3) × (21/2)

= 7/2

Therefore, the average value of the function f(x) = (x + 2) on the interval [0, 3] is 7/2.

The simplified expression is AD^(-1), where A is a matrix, C^(-1) is the inverse of matrix C, and D^(-1) is the inverse of matrix D.

The given expression is (AC^(-1))^(-1)(AC^(-1))(AC^(-1))^(-1)AD^(-1), and the task is to simplify it using the inverse property of matrix multiplication.

According to the inverse property of matrix multiplication, for any square matrix A, if A^(-1) is the inverse of A, then A^(-1)A = I, where I is the identity matrix.

Using this property, we can simplify the given expression as follows:

(AC^(-1))^(-1)(AC^(-1))(AC^(-1))^(-1)AD^(-1)

= AC^(-1)AC^(-1)(AC^(-1))^(-1)AD^(-1) // Applying the inverse property

= AC^(-1)(I)(AC^(-1))^(-1)AD^(-1) // Since A^(-1)A = I

= AC^(-1)(AC^(-1))^(-1)AD^(-1) // Simplifying (I)(AC^(-1)) = AC^(-1)

= AC^(-1)AC(AD^(-1)) // Since (AC^(-1))^(-1) = AC

= I(AD^(-1)) // Since A^(-1)A = I

= AD^(-1) // Since I(B) = B for any matrix B

Therefore, the simplified expression is AD^(-1), where A is a matrix, C^(-1) is the inverse of matrix C, and D^(-1) is the inverse of matrix D.

The Coase theorem suggests that in situations like this, bargaining between the two parties can lead to an efficient outcome. In this case, the smoker and non-smoker (roommate and you) could negotiate to find a solution that minimizes the total cost to both parties.

For example, the smoker could agree to smoke outside or use an air purifier, while the non-smoker could offer to pay a portion of the cost of these solutions. Ultimately, the Coase theorem suggests that as long as property rights are clearly defined and transaction costs are low, the two parties can negotiate to find a mutually beneficial solution to the problem of smoking in the apartment.

1. Clearly defining property rights: Establish whether the apartment has a non-smoking policy or if you have the right to a smoke-free environment within your living space.

2. Engaging in negotiation: Communicate your concerns to your roommate and discuss the negative effects of their smoking on you.

3. Finding a mutually beneficial solution: Both parties can negotiate and arrive at a compromise. This could include your roommate agreeing to smoke outside, designating a specific area for smoking, or using a smoke-filtering device. In some cases, you may also consider offering compensation or splitting the costs of a smoke-filtering device.

By following these steps, both you and your roommate can reach an efficient solution that reduces the cost imposed on you due to your roommate's smoking.

To find the date when the flu will have reached its peak and the number of people who will have the flu on that date, we need to determine the maximum value of the function N(t).

The function N(t) = 90 + (9/4)t - (1/40)t^2 - 120 is a quadratic function in terms of t. The maximum value of a quadratic function occurs at the vertex of the parabola.

To find the vertex of the parabola, we can use the formula t = -b/(2a), where a, b, and c are the coefficients of the quadratic function in the form ax^2 + bx + c.

In this case, a = -1/40, b = 9/4, and c = -120. Plugging these values into the formula, we have:

t = -(9/4)/(2*(-1/40))

Simplifying, we get:

t = -(9/4) / (-1/20)

t = (9/4) * (20/1)

t = 45

Therefore, the date when the flu will have reached its peak is 45 days from the beginning of December. To find the number of people who will have the flu on that date, we can substitute t = 45 into the equation:

N(45) = 90 + (9/4)(45) - (1/40)(45)^2 - 120

N(45) = 90 + 101.25 - 50.625 - 120

N(45) = 120.625

So, on the date 45 days from the beginning of December, approximately 120,625 people will have the flu.

Answer:

9³

Step-by-step explanation:

We need to find the value of \(\dfrac{9^5}{9^2}\).

We know that,

\(\dfrac{x^a}{x^b}=x^{a-b}\)

Here, a = 5 and b = 2.

So,

\(\dfrac{9^5}{9^2}=9^{5-2}\\\\=9^3\)

So, the answer to the given expression is 9³.

The probability of having a girl in the family is also 1/2 since there are only two potential outcomes.

The probability that a family with two children has a boy and a girl is 1/2 because there are two potential birth orders: boy then girl or girl then boy.

Since the order does not matter in this case, the probability is 1/2 + 1/2 = 1.

However, since the question specifies that the family has at least one boy, we can eliminate the girl-boy birth order and conclude that the probability that the family has a boy and a girl is 1/2.

Therefore, the probability of having a girl in the family is also 1/2 since there are only two potential outcomes.

The scale factor of the dilation is approximately 0.49.

To find the scale factor of the dilation, we need to compare the distances between the origin and any two points on the original line with the distances between the origin and their corresponding points on the dilated line.

Let's rearrange the equation of the original line to solve for y:

-17x + 8y = -16

8y = 17x - 16

y = (17/8)x - 2

So the slope of the original line is 17/8, which means that the angle between the original line and the positive x-axis is the arctan(17/8).

Now let's find two points on the original line. We can choose any x values and plug them into the equation to get the corresponding y values. Let's choose x = 0 and x = 8:

When x = 0, y = (17/8)(0) - 2 = -2, so one point is (0,-2).

When x = 8, y = (17/8)(8) - 2 = 14, so another point is (8,14).

The distance from the origin to the first point is √(0²+ (-2)²) = 2, and the distance from the origin to the second point is √(8² + 14²) ≈ 16.49.

Now let's find the corresponding points on the dilated line. The equation of the dilated line is -17x + 8y = -64, which can be rearranged to solve for y:

8y = 17x - 64

y = (17/8)x - 8

We can use the same x values as before:

When x = 0, y = (17/8)(0) - 8 = -8, so the corresponding point on the dilated line is (0,-8).

When x = 8, y = (17/8)(8) - 8 = 0.5, so the corresponding point on the dilated line is (8,0.5).

The distance from the origin to the first point on the dilated line is sqrt(0²+ (-8)²) = 8, and the distance from the origin to the second point on the dilated line is sqrt(8²+ 0.5²) ≈ 8.06.

To find the scale factor of the dilation, we can divide the distances between the origin and the two sets of corresponding points:

scale factor = (distance between corresponding points on dilated line) / (distance between corresponding points on original line)

Using the distances we calculated earlier, we get:

scale factor = (8.06) / (16.49) ≈ 0.49

Therefore, the scale factor of the dilation is approximately 0.49.

The predictor variable is normally distributed is not required for the validity of standard linear regression modeling.

The assumptions that the residuals are normally distributed, the response variable is linearly related to the predictor variable, the response variable is normally distributed, and the variance in the residuals is the same for all values of the predictor variable are required assumptions for the validity of standard linear regression modeling. Additionally, the assumption that the intercept is not zero is not a required assumption, but rather a consideration for the interpretation of the model. In standard linear regression modeling, the following are not required assumptions for validity:
1. The predictor variable is normally distributed.
2. The intercept is not zero.
3. The response variable is normally distributed.
Required assumptions include:
1. The residuals are normally distributed.
2. The response variable is linearly related to the predictor variable.

In Mathematics and Geometry, a parallelogram is a geometrical figure (shape) and it can be defined as a type of quadrilateral and two-dimensional geometrical figure that has two (2) equal and parallel opposite sides.

In order for any quadrilateral to be considered as a parallelogram, two pairs of its parallel opposite sides must be equal (congruent). This ultimately implies that, the diagonals of a parallelogram would bisect one another only when their midpoints are the same:

Answer:

since the equation of the line is perpendicular to y (m2= -1/m1)

using the formula y=mx+c

m1=1/9

since m2 = -1/m1

m2= -1/1/9

m2 = -9

The other line passing through (3,7) has a slope of -9

using the formula

y-y1 = m(x-x1)
