Answer:

f(x) = 2x + 6, x < - 1/5

        -8x + 4, -1/5 ≤ x ≤ 5/3

        -2x - 6, x>5/3

Step-by-step explanation:

3x-5 ≥ 0, 5x + 1 ≥ 0

3x ≥ 5, 5x ≥ -1

x ≥ 5/3, x ≥ -1/5

Intervals: x < -1/5, -1/5 ≤ x ≤ 5/3, x>5/3

Equations:

-(3x - 5) + (5x + 1) = -3x + 5 + 5x + 1 = 2x + 6

-(3x - 5) -(5x + 1) = -3x + 5 - 5x - 1 = -8x + 4

3x - 5 -(5x + 1) = 3x - 5 - 5x - 1 = -2x - 6

Piecewise Function:

f(x) = 2x + 6, x < - 1/5

        -8x + 4, -1/5 ≤ x ≤ 5/3

        -2x - 6, x>5/3

The graph of 5(3x) + 4y + 62 = 12 in the first octant is a plane surface.

The equation 5(3x) + 4y + 62 = 12 can be simplified to 15x + 4y + 62 = 12. By rearranging the equation, we get 15x + 4y = -50. This is a linear equation in two variables, x and y, which represents a plane in three-dimensional space.

To determine if the plane lies in the first octant, we need to check if all coordinates in the first octant satisfy the equation. The first octant consists of points with positive x, y, and z coordinates. Since the given equation only involves x and y, we can ignore the z-coordinate.

For any point (x, y) in the first octant, both x and y are positive. Plugging in positive values for x and y into the equation, we can see that the equation holds true. Therefore, the surface represented by the equation 5(3x) + 4y + 62 = 12 is a plane in the first octant.

The number of shopping centers can be calculated by adding the growth rate multiplied by the number of years after 1998 to the initial count of shopping centers in 1998.

The equation expressing the number of shopping centers in terms of the number of years after 1998 can be represented as:

Number of shopping centers = 41,488 + (year - 1998) ˣgrowth rate

In this equation, the growth rate represents the average annual increase in the number of shopping centers.

By multiplying the number of years after 1998 by the growth rate and adding it to the initial count of shopping centers in 1998 (41,488), we can estimate the number of shopping centers for any given year.

This equation assumes a linear growth model, where the number of shopping centers increases at a constant rate over time.

a) The probability that the student chooses itinerary D is 1/3.

b) The probability that the student arrives late is 1/40.

c) The probability that the student chose itinerary C given that they arrived late is 2/15.

a)The probability that the student chooses itinerary D can be calculated by subtracting the probabilities of choosing itineraries A, B, and C from 1, since the student must choose one of the four itineraries:

P(choosing D) = 1 - P(choosing A) - P(choosing B) - P(choosing C)

P(choosing D) = 1 - 1/3 - 1/4 - 1/12

P(choosing D) = 1 - 4/12 - 3/12 - 1/12

P(choosing D) = 1 - 8/12

P(choosing D) = 4/12

P(choosing D) = 1/3

b) The probability that the student arrives late can be calculated by summing the probabilities of choosing each itinerary and being late:

P(arriving late) = P(choosing A) * P(late|A) + P(choosing B) * P(late|B) + P(choosing C) * P(late|C) + P(choosing D) * P(late|D)

P(arriving late) = (1/3) * (1/20) + (1/4) * (1/10) + (1/12) * (1/5) + (1/3) * 0

P(arriving late) = 1/60 + 1/40 + 1/60 + 0

P(arriving late) = 1/40

c) To find the probability that the student chose itinerary C given that they arrived late, we can use Bayes' theorem:

P(C|late) = (P(late|C) * P(C)) / P(late)\

Using the given information, we have P(late|C) = 1/5, P(C) = 1/12, and P(late) = 1/40 (as calculated in part 2).

P(C|late) = (1/5) * (1/12) / (1/40)

P(C|late) = 8/60

P(C|late) = 2/15

Step-by-step explanation:

To find the length of the hypotenuse (c) in a right triangle with an angle A of 34 degrees and a side length b of 22m, we can use the trigonometric function cosine.

By applying the cosine rule, we can determine c to be approximately 25.32m.

In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side length to the hypotenuse. Applying this concept to our triangle, we have cos(A) = b/c. Rearranging the equation, we get c = b / cos(A). Plugging in the values, c = 22 / cos(34°). By evaluating the cosine of 34 degrees (0.829), we can calculate c to be approximately 25.32 meters, rounded to the nearest hundredth. Thus, the length of the hypotenuse (c) in this right triangle is approximately 25.32 meters.

The number of terms required to achieve a desired accuracy in finding the sum of a series depends on the specific series and the level of accuracy desired. In general, as we add more terms to the series, the approximation of the sum improves, leading to a higher level of accuracy.

To understand how many terms are needed to find the sum with a given accuracy, let's consider an example. Suppose we have an infinite series represented as:

S = a + b + c + d + ...

where 'a', 'b', 'c', 'd', and so on are the terms of the series.

To find the sum of this series, we can take partial sums by adding a certain number of terms. For example, if we add only the first two terms, we get S2 = a + b. If we add the first three terms, we get S3 = a + b + c. The more terms we add, the closer the partial sum gets to the actual sum of the series.

The accuracy of our approximation is determined by the difference between the partial sum and the actual um. To specify the desired accuracy, we can define an error tolerance or a maximum allowable difference between the partial sum and the actual sum.

For instance, if we want our approximation to be accurate within a certain threshold, say ε, we need to find the smallest number of terms that make the difference between the partial sum and the actual sum less than ε.

The number of terms required to achieve the desired accuracy will depend on the convergence properties of the series. Some series converge rapidly, meaning that adding a few terms yields a very accurate approximation, while others converge slowly, requiring a larger number of terms for the same level of accuracy.

To determine the number of terms needed, we can use convergence tests specific to the series at hand. These tests include the Ratio Test, the Root Test, and the Comparison Test, among others. These tests help us determine whether a series converges or diverges and provide insights into its convergence rate.

In summary, the number of terms required to find the sum of a series with a given accuracy depends on the specific series and the desired level of accuracy. By using convergence tests and considering the error tolerance, we can estimate the number of terms needed to achieve the desired accuracy in approximating the sum of the series.
