Carter must go north to get back to City Hall.

First carter needs to travel 5 blocks north and 2 blocks west from his current position.

Let's imagine that Carter's starting point (City Hall) is at the center of a coordinate system, where the positive x-axis points east and the positive y-axis points north. Carter's movements can then be represented as vectors in this coordinate system:

We can add up all of these vectors to find Carter's final position relative to City Hall:

(0, 5) + (5, 0) + (-7, 0) + (0, -5) = (-2, 0)

This means that Carter is now 2 blocks west of City Hall (since the x-coordinate is negative), and he needs to travel 5 blocks north to get back to City Hall.

Therefore, Carter must go north to get back to City Hall.

The subsets Ar = {(x, y) ∈ R² | y = x² + r} form a partition of R². Geometrically, this partition consists of a family of parabolas, each representing a distinct subset of points, obtained by shifting the basic parabola y = x² along the y-axis by an amount determined by the parameter r.

a. To prove that the family of subsets Ar = {(x, y) ∈ R² | y = x² + r} is a partition of R², we need to show two things: (i) the subsets are non-empty, and (ii) the subsets are pairwise disjoint and their union covers R².

(i) Non-emptiness: For any r ∈ R, there exists at least one point (x, y) ∈ Ar, since we can choose x = 0 and y = r, which satisfies the equation y = x² + r.

(ii) Pairwise disjoint and covering R²: Let Ar and As be two subsets with r ≠ s. We need to show that Ar ∩ As = ∅. Suppose there exists a point (x, y) ∈ Ar ∩ As. Then, y = x² + r and y = x² + s. Subtracting these equations, we get r - s = 0, which implies r = s. This contradicts our assumption that r ≠ s. Therefore, Ar and As are disjoint.

Furthermore, for any point (x, y) ∈ R², we can assign it to a specific subset Ar such that y = x² + r, for some r ∈ R. Thus, the union of all Ar covers R².

Therefore, the family of subsets Ar = {(x, y) ∈ R² | y = x² + r} forms a partition of R².

b. Geometrically, the partition described by the subsets Ar = {(x, y) ∈ R² | y = x² + r} represents a family of parabolas in the xy-plane. Each parabola is obtained by shifting the vertex of the basic parabola y = x² along the y-axis by an amount determined by the parameter r.

The partition covers the entire plane, with each parabola representing a distinct subset of points. The parabolas open upwards and become steeper as the absolute value of r increases.

The array A after the first PARTITION() call is ⟨8, 7, 3, 5, 9, 10, 30, 18, 15, 25⟩ and after the second PARTITION() call is {3, 5, 7, 8, 9, 10, 18, 15, 25, 30}.

The Quicksort algorithm partitions an array into two sub-arrays and sort them recursively.

The partitioning method is the core part of Quicksort. In this problem, we are running the Quicksort algorithm on the array A=⟨25,8,30,9,7,15,3,18,5,10⟩.

We will use the PARTITION() call to split the elements into sub-arrays and sort them.

The first PARTITION() call selects a pivot element and partitions the array such that all the elements less than pivot are on the left, and all the elements greater than pivot are on the right.

This pivot position is the correct position of the element in the sorted array.

Here, the pivot element is 10.

We select it as the pivot and partition the array.

We will now write the array A after the first PARTITION() call:⟨8, 7, 3, 5, 9, 10, 30, 18, 15, 25⟩.

The second PARTITION() call will partition the left and right sub-arrays.

Here, the left sub-array is {8, 7, 3, 5, 9} and the right sub-array is {30, 18, 15, 25}.

For the left sub-array, the pivot element is 9, and for the right sub-array, the pivot element is 18.

We will now write the array A after the second PARTITION() call:{3, 5, 7, 8, 9, 10, 18, 15, 25, 30}.

Hence, the array A after the first PARTITION() call is ⟨8, 7, 3, 5, 9, 10, 30, 18, 15, 25⟩ and after the second PARTITION() call is {3, 5, 7, 8, 9, 10, 18, 15, 25, 30}.

The coordinates in the first question is in planar format and is using the SPCS coordinate system. The second set of coordinates in the second question is in planar format , but it is using the UTM coordinate system.

In the first question, the coordinates provided are in the format of feet, indicating a planar coordinate system. Additionally, the mention of SPCS (State Plane Coordinate System) confirms that the coordinates are using this system.

The SPCS divides the United States into multiple zones, each with its own coordinate system for accurate mapping and surveying.

To convert the top set of coordinates into decimal degrees and degrees, minutes, and seconds, we would need to know the specific SPCS zone used. Without that information, it is not possible to accurately convert the coordinates.

In the second question, the coordinates collected by Dr. Eversole from Lake Titicaca in Bolivia are mentioned. These coordinates are in planar format as well, but they are using the UTM (Universal Transverse Mercator) coordinate system.

UTM divides the Earth into 60 zones, each representing a longitudinal strip of the Earth's surface. It is a widely used coordinate system for mapping and navigation purposes.

To convert the given UTM coordinates into decimal degrees or degrees, minutes, and seconds, we would need to know the UTM zone and the hemisphere (Northern or Southern). Without this information, a precise conversion is not possible.

Answer:

\(P =5x-260\)

Step-by-step explanation:

Given

\(R = 3x^2 + 4x - 60\) --- Revenue

\(C = 3x^2 - x + 200\) --- Cost

Required

The expression for profit (P)

This is calculated as:

\(P =R - C\)

So, we have:

\(P =3x^2 + 4x - 60 - (3x^2 -x+200)\)

Open bracket

\(P =3x^2 + 4x - 60 - 3x^2 +x-200\)

Collect like terms

\(P =3x^2 - 3x^2+ 4x +x- 60-200\)

\(P =5x-260\)

If the profit is the difference between the revenue and the cost, 5x – 260  expression represents the profit. Correct option is 3.

The profit is calculated by subtracting the cost from the revenue. In mathematical terms, the profit (P) can be represented as:

Profit (P) = Revenue - Cost

Among the given options:

1. 3x - 260

2. 3x + 140

3. 5x - 260

4. 5x + 140

We need an expression where the first term represents the revenue and the second term represents the cost, so that when we subtract the cost from the revenue, we get the profit.

Option 3, 5x - 260, fits this pattern:

- Revenue: 5x

- Cost: 260

When we subtract the cost from the revenue:

Profit (P) = Revenue - Cost = 5x - 260

So, option 3, 5x - 260, is the expression that represents the profit.

Answer:

Option (D)

Step-by-step explanation:

If the two points \((x_1,y_1)\) and \((x_2,y_2)\) are lying of the line.

Slope of the line represented by the function 'f' = \(\frac{y_2-y_1}{x_2-x_1}\)

Two points are lying on the line are (-2, 4) and (0, -2).

Slope of the line passing through these points 'm' = \(\frac{4+2}{-2-0}\)

m = -3

Y-intercept of the line 'b' = -2 [From the graph]

Therefore, equation of the function will be,

f(x)  = (-3)x - 2

f(x) = -3x - 2

Similarly, for other function represented by the line in red,

Slope of the line passing through (-6, 0) and (0, 6) = \(\frac{6-0}{0+6}\)

m' = 1

Y-intercept of g(x) = 5 [From the graph]

Equation that represents the function g(x) = 1.x + 5

g(x) = x + 5

For g(x) = f(x)

-3x - 2 = x + 6

-3x - x = 2 + 6

-4x = 8

x = -2

Therefore, for x = -2 both the functions will have the value.

f(-2) = g(-2)

Solutions: x = 7, y = 9;  or (7, 9)

Step-by-step explanation:

Given the following systems of linear equations:

7x - 8y = -23

7x - 7y = -14

Since the coefficients of x in the given system have the same sign, we could use the process of elimination by subtracting the two equations.

    7x - 8y = -23

-   7x - 7y = -14    

             -y = -9  

Divide both sides by -1 to solve for y:

\(\frac{-y}{-1} = \frac{-9}{-1}\)

y = 9

Substitute the value of y into either one of the given equations to solve for x:

7x - 7y = -14

7x - 7(9) = -14

7x - 63 = -14

Add 63 to both sides:

7x - 63 + 63 = -14 + 63

7x = 49

Divide both sides by 7 to solve for x:

\(\frac{7x}{7} = \frac{49}{7}\)

x = 7

Double-check whether x = 7 and y = 9 are valid solutions to the given system:

x = 7, y = 9:

7(7) - 8(9) = -23

49 - 72 = -23

-23 = -23 (True statement).

7(7) - 7(9) = -14

49 - 63 = -14

-14 = -14 (True statement).

Therefore, the solution to the given systems of linear equations are x = 7, and y = 9, or (7, 9).

Therefore, the packages of buns and hotdogs will work evenly for 5 groups of 40 people each, which is a total of 200 people.

To plan a party for more than 200 people, the number of guests for which both packages of buns and hotdogs will work evenly is 40 people. Here's an explanation of how to get this answer: First, we need to find the common multiple of 8 and 10 since buns come in packs of 8 while hotdogs come in packs of 10. The common multiple of 8 and 10 is 40. Next, we need to divide the total number of people by the common multiple of 8 and 10, which is 40. So, 200 divided by 40 equals 5. Therefore, the packages of buns and hotdogs will work evenly for 5 groups of 40 people each, which is a total of 200 people. Any additional guests can be accommodated by purchasing extra packages of buns and hotdogs. So, the answer is 40 guests.
