The relation R defined as R = {(x,x) : 1 € Z} on Z, where Z is the set of integers, is a relation where an element in Z is related to itself if and only if it is equal to 1.

To determine whether the relation R is reflexive, symmetric, and transitive, we need to consider the properties of relations.

A relation is reflexive if every element in the set is related to itself. In this case, since R contains only pairs of the form (x,x), we can say that R is reflexive if and only if 1 € Z. That is, if and only if 1 is an integer, then R is reflexive. Since 1 is an integer, R is reflexive.

A relation is symmetric if for any two elements (a, b) in the relation, (b, a) is also in the relation. Since R only contains pairs of the form (x,x), it is symmetric if and only if for any integer x, (x,x) is in the relation, then (x,x) is also in the relation. Therefore, R is symmetric.

A relation is transitive if for any three elements (a, b), (b, c) in the relation, (a, c) is also in the relation. In this case, since R only contains pairs of the form (x,x), we can say that R is transitive if and only if for any integers x, y, z such that (x, y) and (y, z) are in R, then (x, z) is also in R. However, since there are no pairs (x, y) and (y, z) in R except for when x=y=z=1, there are no pairs (x, z) in R for which transitivity needs to be checked. Therefore, we can say that R is transitive vacuously.

In conclusion, the relation R defined as R = {(x,x) : 1 € Z} on Z is reflexive, symmetric, and transitive.

a) To calculate the missing values, we first need to find the 2018 turnover value. That is, 290.62 M Ft.

b) Average Relative Change =  5.18% and Average Absolute Change = 13.54 M Ft.

c) The ratios for 2016 indicate that the firm experienced a 4% increase in turnover compared to the previous year (2015).

a) To calculate the missing values, we first need to find the 2018 turnover value. We know that the 2015 turnover is 100% of the previous year, so 2015 and 2014 turnover values are the same (250 M Ft). Now we can use the ratios given for the subsequent years:

2016 Turnover = 2015 Turnover * (100% + Ratio)
260 M Ft = 250 M Ft * (100% + Ratio)
Ratio = (260 / 250) - 1 = 0.04 or 4%

2017 Turnover = 2016 Turnover * (100% + Ratio)
275 M Ft = 260 M Ft * (100% + Ratio)
Ratio = (275 / 260) - 1 ≈ 0.0577 or 5.77%

2018 Turnover = 2017 Turnover * (100% + Ratio)
2018 Turnover = 275 M Ft * (100% + 0.0577) ≈ 290.62 M Ft

b) Now, we can calculate the average relative and absolute change:
Average Relative Change = (4% + 5.77% + 5.77%)/3 ≈ 5.18%

Absolute Change (2016) = 260 - 250 = 10 M Ft
Absolute Change (2017) = 275 - 260 = 15 M Ft
Absolute Change (2018) = 290.62 - 275 ≈ 15.62 M Ft
Average Absolute Change = (10 + 15 + 15.62) / 3 ≈ 13.54 M Ft

c) The ratios for 2016 indicate that the firm experienced a 4% increase in turnover compared to the previous year (2015). This means the firm was successful in generating more revenue in 2016 as compared to 2015, which could be attributed to various factors such as improved marketing strategies, expansion in the market, or better product offerings.

a. This is a combination because the order in which the students are chosen does not matter, only the group of four students is selected.
b. There are 4845 different ways that 4 students can be chosen from a group of 20.

a. This is a combination because the order of the chosen students does not matter. In a permutation, the order matters, whereas in a combination, it does not.

b. To find the number of different ways 4 students can be chosen from a group of 20, use the combination formula:

C(n, k) = n! / (k!(n-k)!)

Where n = the total number of students (20), k = the number of students to be chosen (4), and ! denotes factorial.
The number of different ways 4 students can be chosen from a group of 20 can be calculated using the combination formula:

nCr = n! / r!(n-r)!

Where n is the total number of students (20) and r is the number of students being chosen (4).

So,

20C4 = 20! / 4!(20-4)!
C(20, 4) = 20! / (4!(20-4)!)
C(20, 4) = 20! / (4! * 16!)
C(20, 4) = 2,432,902,008,176,640,000 / (24 * 20,922,789,888,000)

The distance from y to W is sqrt(10), which is the exact answer using radicals.

Let's start by finding the projection of y onto the subspace W spanned by v1 and v2. The projection of y onto W is given by:

projW(y) = ((y · v1)/||v1||^2)v1 + ((y · v2)/||v2||^2)v2

where · denotes the dot product and || || denotes the norm or length of a vector.

Using the given information, we have:

v1 = [1 0 1 0], v2 = [0 1 0 1], and y = [2 4 0 0]

We can calculate the dot products and norms as follows:

||v1||^2 = 1^2 + 0^2 + 1^2 + 0^2 = 2

||v2||^2 = 0^2 + 1^2 + 0^2 + 1^2 = 2

y · v1 = 2(1) + 4(0) + 0(1) + 0(0) = 2

y · v2 = 2(0) + 4(1) + 0(0) + 0(1) = 4

Therefore, the projection of y onto W is:

projW(y) = ((2/2)[1 0 1 0]) + ((4/2)[0 1 0 1])

= [1 0 1 0] + [0 2 0 2]

= [1 2 1 2]

The closest point to y in W is the projection projW(y), so we have:

v = [1 2 1 2]

The distance from y to W is the length of the vector y - v, which we can calculate as:

||y - v|| = ||[2 4 0 0] - [1 2 1 2]||

= ||[1 2 -1 -2]||

= sqrt(1^2 + 2^2 + (-1)^2 + (-2)^2)

= sqrt(10)

Therefore, the distance from y to W is sqrt(10), which is the exact answer using radicals.

To calculate the standard deviation of X, we first need to find the mean or expected value of X. We can do this by integrating the given pdf over the range 0.90 to 1.80:

E(X) = ∫[0.90,1.80] x*f(x) dx

= ∫[0.90,1.80] x*(265/652)*x^3 dx

= (265/652) * ∫[0.90,1.80] x^4 dx

= (265/652) * [x^5/5] from x=0.90 to x=1.80

≈ 1.315

Next, we can calculate the variance of X using the formula:

Var(X) = E(X^2) - [E(X)]^2

To find E(X^2), we integrate the pdf squared over the same range:

E(X^2) = ∫[0.90,1.80] x^2*f(x) dx

= ∫[0.90,1.80] x^2*(265/652)*x^3 dx

= (265/652) * ∫[0.90,1.80] x^5 dx

= (265/652) * [x^6/6] from x=0.90 to x=1.80

≈ 1.464

Var(X) = E(X^2) - [E(X)]^2

≈ 1.464 - 1.315^2

≈ 0.024

Finally, we take the square root of the variance to obtain the standard deviation:

The probability P(56< X ≤ 6) is 0.0398. ​To draw a normal curve with the area corresponding to the probability shaded we would shade the area to the right of 56 and to the left of 6 on the curve.

To compute the probability P(56< X ≤ 6), we first need to standardize the values using the formula:
z = (x - μ) / σ
where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

For 56:
z = (56 - 45) / 10 = 1.1

For 6:
z = (6 - 45) / 10 = -3.9

Now, we can look up the probabilities for these values of z in a standard normal distribution table or use a calculator to find the area under the curve between these two values:
P(56< X ≤ 6) = P(1.1 < Z ≤ -3.9)

Using a standard normal distribution table or a calculator, we find that:
P(56< X ≤ 6) = 0.0398 (rounded to four decimal places)

To draw the normal curve with the shaded area corresponding to this probability, we can use a graphing calculator or a standard normal distribution table. The area between 56 and 6 corresponds to the area to the right of 56 minus the area to the right of 6.

Where:
PV = Present Value (cash payment)
PMT = Monthly payment ($1074)
r = Monthly interest rate
n = Number of payments (5 years * 12 months = 60)

First, we need to find the monthly interest rate. Since the interest is compounded semi-annually, we'll divide the annual interest rate by 2, and then convert it to a monthly rate:

Semi-annual interest rate = 11% / 2 = 5.5% = 0.055

To orthogonally diagonalize the matrix A, we will follow these steps:
1. Find the eigenvalues of matrix A.
2. Find the eigenvectors corresponding to each eigenvalue.
3. Normalize the eigenvectors to form an orthogonal basis.
4. Construct the orthogonal matrix Q and the diagonal matrix D.

To orthogonally diagonalize the matrix A, we need to find the eigenvalues and eigenvectors of A.

A = [[3, -1], [-1, 3]]

The characteristic polynomial of A is:

det(A - λI) = det([[3-λ, -1], [-1, 3-λ]]) = (3-λ)² - 1 = λ² - 6λ + 8 = (λ-2)(λ-4)

So the eigenvalues are λ₁ = 2 and λ₂ = 4.

To find the eigenvectors, we need to solve the system of equations:

(A - λ₁I)x = 0 and (A - λ₂I)x = 0

For λ₁ = 2, we have:

(A - 2I)x = [[1, -1], [-1, 1]]x = 0

This system has two linearly independent solutions:

v₁ = [1, 1] and v₂ = [-1, 1]

For λ₂ = 4, we have:

(A - 4I)x = [[-1, -1], [-1, -1]]x = 0

This system has one linearly independent solution:

v₃ = [1, -1]

To orthogonalize the eigenvectors, we need to normalize them and put them as columns of an orthogonal matrix Q.

Q = [[1/√2, -1/√2, 0], [1/√2, 1/√2, 0], [0, 0, 1]]

The diagonal matrix D has the eigenvalues on the diagonal:

D = [[2, 0], [0, 4]]

Finally, we can check that QTAQ = D:

QTAQ = [[1/√2, -1/√2, 0], [1/√2, 1/√2, 0], [0, 0, 1]]T[[3, -1], [-1, 3]][[1/√2, -1/√2, 0], [1/√2, 1/√2, 0], [0, 0, 1]] = [[2, 0, 0], [0, 4, 0], [0, 0, 4]] = D

(a) Since / is the perpendicular bisector of AC, it passes through the midpoint M of AC. The coordinates of M can be found by taking the average of the x-coordinates and the average of the y-coordinates of A and C, respectively:

x-coordinate of M = (-3 + 5)/2 = 1

y-coordinate of M = (4 + 2)/2 = 3

Therefore, the coordinates of M are (1, 3). Since / is perpendicular to AC, its slope is the negative reciprocal of the slope of AC:

slope of AC = (2 - 4)/(5 - (-3)) = -1/2

slope of / = 2 (negative reciprocal of -1/2)

Using the point-slope form of the equation of a line with the point M, we get:

y - 3 = 2(x - 1)

Simplifying and rearranging, we get:

y = 2x + 1

Therefore, an equation of / is y = 2x + 1.

(b) The length of AC can be found using the distance formula:

AC = √[(5 - (-3))^2 + (2 - 4)^2] = √64 + 4 = √68 = 2√17

Therefore, the exact length of AC is 2√17.

(c) Since BM is a median of triangle ABC, it divides AC into two equal parts. Therefore, BM has length half of AC:

BM = AC/2 = (1/2)(2√17) = √17

Therefore, the exact length of BM is √17.

(d) Since B lies on line /, its x-coordinate is 5 (since / passes through point (5, 2)). To find the y-coordinate, we can substitute x = 5 into the equation of /:

y = 2x + 1 = 2(5) + 1 = 11

Therefore, the coordinates of B are (5, 11).

Alternatively, we can use the fact that B lies on the circumcircle of triangle ABC (since angle ABC is a right angle) to find its coordinates. The circumcenter of triangle ABC is the midpoint of AC (which is also the intersection of the perpendicular bisectors of AC), so the coordinates of the circumcenter are (1, 3). The radius of the circumcircle is half of AC, so it is √17. Therefore, the equation of the circumcircle is:

(x - 1)^2 + (y - 3)^2 = 17

Since B lies on the circumcircle, its coordinates satisfy this equation. Substituting x = 5, we get:

(5 - 1)^2 + (y - 3)^2 = 17

16 + (y - 3)^2 = 17

(y - 3)^2 = 1

y - 3 = ±1

Solving for y, we get y = 2 or y = 4. Since B lies on line /, its y-coordinate must be greater than 2, so y = 4. Therefore, the coordinates of B are (5, 4).

(e) There are two possible positions of B, which are reflections of each other across the line /. One position has coordinates (5, 11), as found in part (d), and the other has coordinates (-3, 2). To find the coordinates of the second position, we can reflect point A across line / to get the point B':

B' has the same x-coordinate as A, which is -3. To find its y-coordinate, we can use the equation

The given equation is a constant function with a horizontal line passing through (0, 1). Here option E is the correct answer.

The given equation, f(x) = 1, represents a constant function, where the output or value of the function is always equal to 1 for any input value of x. This is a special case of a linear function, where the slope is zero and the y-intercept is a non-zero constant value.

Among the four given options, none of them is a constant function. A reciprocal function, y = 1/x, has a variable slope and a vertical asymptote at x = 0. A square root function, y = √x, has a non-linear shape and a domain of x ≥ 0. An absolute value function, y = |x|, has a V-shaped graph and is symmetric around the y-axis. A cube root function, y = ∛x, is also non-linear and has a domain of all real numbers.

Therefore, the correct answer is not listed among the options, and the function f(x) = 1 does not belong to any of the parent functions mentioned. It is a simple constant function with a horizontal line as its graph, passing through the point (0, 1) on the y-axis.

I beleive c. i had the same question last year, and i believe i got the answer right. so sorry if its wrong. hope this helps.

Step-by-step explanation:

The area of the triangles are: (a) 8.4 square units. (b) 526.1 square units. (c) 96.7 square units.

(a) Area = (1/2)ab*sin(y)

where y is the angle opposite to side c.

using the law of sines:

b/sin(B) = a/sin(a)

b/sin(16°) = 6/sin(16°)

b = 6*sin(16°)/sin(16°) = 6 units

Now, the sum of the angles in a triangle is 180°:

y = 180° - a - B

y = 180° - 16° - 16°

y = 148°

Finally,

Area = (1/2)66*sin(148°)

Area ≈ 8.4 square units

Therefore, the area of the triangle is approximately 8.4 square units.

(b) using the law of sines:

b/sin(B) = c/sin(y)

b/sin(180°-a-B) = 27.55/sin(56°)

b/sin(76°) = 27.55/sin(56°)

b ≈ 21.94 units

Now,

Area = (1/2)48sin(56°)*21.94/sin(76°)

Area ≈ 526.1 square units (rounded to the nearest tenth)

Therefore, the area of the triangle is approximately 526.1 square units.

(c) using the law of cosines:

b^2 = a^2 + c^2 - 2accos(B)

12.5^2 = 14^2 + c^2 - 214ccos(53°)

c ≈ 13.3 units

Now, the sum of the angles in a triangle is 180°:

y = 180° - a - B

y = 180° - 53° - arcsin(c*sin(53°)/14)

y ≈ 74.8°

Finally,

Area = (1/2)1413.3*sin(74.8°)

Area ≈ 96.7 square units

Therefore, the area of the triangle is approximately 96.7 square units.
