Because each foot is 12 inches and 12*7=84 and 84+5=89!

It is proved that if A1, A2,...,An and B are sets, then (A1 −B) ∩(A2 −B) ∩...∩(An−B) = (A1 ∩A2 ∩...∩An) −B.

To prove the given statement using induction, we need to show that it holds true for a base case and then demonstrate that if it holds for an arbitrary value of 'n', it also holds for 'n + 1'.

Base Case (n = 1):

Let's consider the base case where 'n = 1'. We have two sets A1 and B, and we want to prove that (A1 - B) = (A1 - B).

(A1 - B) ∩ (A1 - B) = (A1 - B)  [Using the definition of set difference]

This satisfies the given statement for the base case.

Inductive Step

Assuming that the given statement holds for 'n = k', let's prove that it holds for 'n = k + 1'.

We have sets A1, A2, ..., Ak+1, and B. We want to prove that:

(A1 - B) ∩ (A2 - B) ∩ ... ∩ (Ak+1 - B) = (A1 ∩ A2 ∩ ... ∩ Ak+1) - B

Using the inductive hypothesis, we can rewrite the left-hand side (LHS) as:

[(A1 ∩ A2 ∩ ... ∩ Ak) - B] ∩ (Ak+1 - B)

To prove the equality, we need to show that each side is a subset of the other.

1. LHS ⊆ RHS:

Let x be an arbitrary element in LHS. This means that x belongs to each set in the intersection on the LHS: (A1 - B), (A2 - B), ..., (Ak+1 - B). By the definition of set intersection, x also belongs to (A1 - B), (A2 - B), ..., (Ak - B), and (Ak+1 - B).

Since x belongs to each set in the intersection (A1 - B) ∩ (A2 - B) ∩ ... ∩ (Ak+1 - B), it follows that x belongs to (A1 ∩ A2 ∩ ... ∩ Ak) - B. Therefore, x ∈ RHS.

2. RHS ⊆ LHS:

Now let y be an arbitrary element in RHS. This means that y belongs to (A1 ∩ A2 ∩ ... ∩ Ak+1) - B. By the definition of set difference, y belongs to (A1 ∩ A2 ∩ ... ∩ Ak+1) and y does not belong to B.

Since y belongs to (A1 ∩ A2 ∩ ... ∩ Ak+1), it implies that y belongs to each set A1, A2, ..., Ak+1. By the definition of set difference, y does not belong to B, so y also belongs to each set (A1 - B), (A2 - B), ..., (Ak+1 - B).

Therefore, y ∈ LHS.

Since we have shown that LHS ⊆ RHS and RHS ⊆ LHS, it follows that (A1 - B) ∩ (A2 - B) ∩ ... ∩ (Ak+1 - B) = (A1 ∩ A2 ∩ ... ∩ Ak+1) - B.

By the principle of mathematical induction, the statement holds for all 'n', completing the proof.

Answer:

The angle of elevation is 17°.

Step-by-step explanation:

Let's draw the scenario to better understand the problem:

Focusing on the right triangle formed, it appears that we get measures of the two sides of the right triangles.

Opposite Side = 3 Ft.

Adjacent Side = 10 Ft.

To find the angle of elevation, we will be using the Targent Function:

[tex]targent \: 0 = \frac{opposite \: side}{adjacent \: side} \\ targent \: 0 = \frac{3}{10} \\ 0 = {targent}^{ - 1} ( \frac{3}{10} ) \\ 0 = 16.69924423399 = 17[/tex]

Therefore, the angle of elevation is 17°.

This indicates that vector 2AB has a length of 165.

Given the points A(-2, 0), B(6, 16), C(1, 4), D(5, 4), and E, let's determine the length of the vector 2AB. To begin, we must determine the distance that separates points A and B. The distance formula is as follows: Equation for distance: We can calculate d as [(x2 - x1)2 + (y2 - y1)2] using the distance formula: Spot = [(6 - (- 2))2 + (16 - 0)2] = [(6 + 2)2 + (16)2] = [(8)2 + (16)2] = [(64 + 256) = 320 = 8] Now, we can deduct the directions of point A from guide B toward decide the vector Stomach muscle:

To find 2AB, simply multiply each part of AB by 2: AB = (6 - (-2)i + (16 - 0)j = 8i + 16j 2AB = 2(8i + 16j) = 16i + 32j. Last but not least, we must ascertain the magnitude of 2AB. The extent recipe is as per the following: Size formula: Using the magnitude formula, we get: ||v|| = (v12 + v22). ||2AB|| = (162 + 322) = (256 + 1024) = (1280 + 165). This indicates that vector 2AB has a length of 165.

Answer:

10 feets

Step-by-step explanation:

Given that:

Angle, θ = 4π/3

Radius, r = 2.5 feets

To obtain how Far Reagan traveled, we calculate the Length of the arc, s

s = r*θ

s = 2.5 feets * 4π/3

s = 10π/3

s = 10.4719

To the nearest foot ; distance traveled by Reagan is 10 feets

The linear speed of a point on the circumference is approximately 9895 feet per minute.

(a) To find the angular speed in radians per minute, we need to convert the given rotational speed from rpm (revolutions per minute) to radians per minute. Since there are 2π radians in one revolution, we can use the conversion factor:

Angular speed (in radians per minute) = Rotational speed (in rpm) * 2π

Given that the rotational speed is 2100 rpm, we can calculate the angular speed:

Angular speed = 2100 rpm * 2π ≈ 13194 radians per minute

Therefore, the angular speed of the wheel is approximately 13194 radians per minute.

(b) To find the linear speed of a point on the circumference in feet per minute, we can use the formula:

Linear speed = Angular speed * Radius

Given that the radius of the wheel is 9 inches, we need to convert it to feet:

Radius = 9 inches * (1 foot / 12 inches) = 0.75 feet

Now, we can calculate the linear speed:

Linear speed = 13194 radians per minute * 0.75 feet ≈ 9895 feet per minute

Therefore, the linear speed of a point on the circumference is approximately 9895 feet per minute.

The given functions f(n) = 11 and g(n) = (3/4)^(n-1) can be combined to create a geometric sequence. The nth term of a geometric sequence is given by a_n = a_1 * r^(n-1), where a_1 is the first term and r is the common ratio.

In a geometric sequence, each term is obtained by multiplying the previous term by a constant ratio. In this case, the first term is given as 11, and the common ratio is (3/4).

The nth term of a geometric sequence is calculated using the formula a_n = a_1 * r^(n-1), where a_1 is the first term, r is the common ratio, and n is the position of the term. By substituting the values into the formula, we can find the 9th term.

The percent tip is 13.2%.

To find out what percentage Patrick gave as tip, we need to divide the tip amount by the total bill amount and then convert the result into a percentage.

For this question:

Patrick left an $7 tip on a $53 restaurant bill. What percent tip is that?

Solution:The percentage of tip can be found using the following formula:

% = (Tip amount / Total bill amount) x 100

Plugging in the given values we get:

% = (7 / 53) x 100% = 0.132 x 100% = 13.2 %

One faces a tradeoff between the number of courses and hours of work due to limited available time. Taking X courses while working X hours per week is impossible as it exceeds the time constraint.

The tradeoff between the number of courses and hours of work arises due to the finite number of hours available in a week. Assuming an individual has X hours per week, this time must be divided between courses and work.

To achieve a B or better in a course, it is necessary to dedicate at least X hours per course per week. Therefore, taking X courses while working X hours per week would require dedicating X hours per course, resulting in a total time commitment exceeding the available X hours.

Conversely, if only one class is taken while working X hours per week, the time commitment for a single course is less than X hours. This scenario leaves a significant amount of free time remaining, as the total time dedicated to the course and work does not exhaust the available X hours.

In summary, the tradeoff occurs because the time available is limited, and the minimum time requirement per course restricts the number of courses that can be taken while maintaining a specific work schedule.

1) The solutions to the equation system are x₁ = 11/39 and x₂ = -7/39.

2) The difference quotient as a function of Δr is -4.

3)  f'(-1) = -4 and f'(5) = -4.

To solve the equation system using Cramer's rule, we need to find the determinant of the coefficient matrix A and the determinants of the matrices obtained by replacing each column of A with the column on the right-hand side.

The given equation system is:

8x₁ + 9x₂ = 2

11x₁ + 2x₂ = 3

7x₁ + 6x₂ = 1

Step 1: Calculate the determinant of the coefficient matrix A.

A = |8 9|

|11 2|

|7 6|

|A| = (8 * 2) - (9 * 11)

    = -78

Step 2: Calculate the determinant of the matrix obtained by replacing the first column of A with the column on the right-hand side.

A₁ = |2 9|

|3 2|

|1 6|

|A₁| = (2 * 2) - (9 * 3)

     = -22

Step 3: Calculate the determinant of the matrix obtained by replacing the second column of A with the column on the right-hand side.

A₂ = |8 2|

|11 3|

|7 1|

|A₂| = (8 * 3) - (2 * 11)

     = 14

Step 4: Calculate the solutions x₁ and x₂ using Cramer's rule.

x₁ = |A₁| / |A|

   = -22 / -78

   = 11/39

x₂ = |A₂| / |A|

    = 14 / -78

    = -7/39

Therefore, the solutions to the equation system are x₁ = 11/39 and x₂ = -7/39.

Now, let's move on to the second part of your question regarding the function f(r) = 57 - 4r.

(a) To find the difference quotient as a function of Δr (Δr represents the change in r):

Difference quotient = (f(r + Δr) - f(r)) / Δr

Expanding and simplifying the expression:

Difference quotient = (57 - 4(r + Δr) - (57 - 4r)) / Δr

                                = (57 - 4r - 4Δr - 57 + 4r) / Δr

                                = -4Δr / Δr

                                = -4

Therefore, the difference quotient as a function of Δr is -4.

(b) To find f'(-1) and f'(5), we need to find the derivative of f(r) with respect to r.

f'(r) = d/dx (57 - 4r)

     = -4

Substituting r = -1 and r = 5 into f'(r), we get:

f'(-1) = -4

f'(5) = -4

Therefore, f'(-1) = -4 and f'(5) = -4.
