(i) R is not reflexive, symmetric, vacuously antisymmetric, and not transitive.
(ii) It is important that S has at least two different elements because if S had only one element, then the power set P(S) would contain only two sets: the empty set and the set S itself.
(iii) If S was empty, there would be no elements in S, and hence the power set P(S) would only contain the empty set. The answers regarding reflexivity, symmetry, antisymmetry, and transitivity would all change, and the relation R would not possess any of these properties. If S had only one element, the power set P(S) would contain two sets: the empty set and the singleton set containing the one element of S. The relation R would be reflexive, symmetric, antisymmetric, and transitive, as it satisfies all these properties by definition.
(i)Let's analyze the properties of relation R on P(S):
Reflexive: A relation R is reflexive if for every element x in the set S, (x, x) belongs to R. In this case, since the intersection of any set with itself is never empty, the relation R is not reflexive.
Symmetric: A relation R is symmetric if for every pair (x, y) in R, (y, x) also belongs to R. In this case, since the intersection of two sets is commutative, if (X, Y) belongs to R, then (Y, X) also belongs to R. Thus, the relation R is symmetric.
Antisymmetric: A relation R is antisymmetric if for every distinct pair (x, y) in R, (y, x) does not belong to R. Since the relation R is defined by the condition X∩Y = φ, there are no distinct pairs (X, Y) that satisfy the condition. Therefore, the relation R is vacuously antisymmetric.
Transitive: A relation R is transitive if for every three sets X, Y, and Z such that (X, Y) belongs to R and (Y, Z) belongs to R, then (X, Z) also belongs to R. In this case, if X∩Y = φ and Y∩Z = φ, it does not imply that X∩Z = φ. Hence, the relation R is not transitive.
(ii) In this scenario, the relation R would not have any pairs (X, Y) where X and Y are non-empty subsets of S, because the intersection of any two non-empty subsets would never be empty. Thus, the relation R would be trivial and uninteresting.
(iii) In this case, since there are no non-empty subsets in P(S), the relation R would not have any pairs (X, Y) where X and Y are non-empty subsets of S.
In this case, the relation R would have only one possible pair (X, Y) with X and Y being the empty set, and their intersection would indeed be empty.

f(x)=x^2. What is g(x)?
Answer:
D, g(x) = 1/4 x^2
Step-by-step explanation:
You can try plugging in the x and y values into each equation. The answer to this would be D, where if you plug in 2 as the x value, you get 1/4 * 4 which equals 1. This also makes sense because 2x would have a narrower curve while 1/2x would have a wider curve.
A company Charting its profits notices that the relationship between the number of units sold,x, and the profit,P, is a linear. If 170 units sold results in $20 profit and 220 units sold results in $2820 profit, write the profit function for this company.

Find the marginal profit
$
Step-by-step explanation:
a linear relationship or function is described in general as
y = f(x) = ax + b
Because the variable term has the variable x only with the exponent 1, this makes this a straight line - hence the name "linear".
here f(x) is P(x) :
P(x) = ax + b
now we are using both given points (ordered pairs) to calculate a and b :
20 = a×170 + b
2820 = a×220 + b
to eliminate first one variable we subtract equation 1 from equation 2 :
2800 = a×50
a = 2800/50 = 280/5 = 56
now, we use that in any of the 2 original equations to get b :
20 = 56×170 + b
b = 20 - 56×170 = 20 - 9520 = -9500

4. Brooke earns a salary of $38 000 per year as a cook and works part-time in a department
store.
Her part-time job pays $10.25 per hour and she usually works 12 hours per week.
a) Determine her monthly income.
b) She is looking at renting a new apartment. The rent is $975 per month and includes
utilities. If she takes this apartment, will it fall within the guidelines for housing?
a) Brooke's monthly income is $3,166.67 from her full-time job as a cook, and an additional $532.59 from her part-time job, resulting in a total monthly income of $3,699.26.
b) Yes, the rent of $975 per month for the new apartment falls within the housing guideline of spending 30% or less of her monthly income on housing.
a) To determine Brooke's monthly income, we need to calculate her earnings from both her full-time and part-time jobs.
Full-time job income: Brooke earns $38,000 per year as a cook.
To find her monthly income from this job, we divide her annual salary by 12:
Monthly income from full-time job = $38,000 / 12 = $3,166.67
Part-time job income: Brooke earns $10.25 per hour and works 12 hours per week.
To find her weekly income from this job, we multiply her hourly rate by the number of hours she works:
Weekly income from part-time job = $10.25/hour x 12 hours/week = $123
To find her monthly income, we multiply her weekly income by the average number of weeks in a month (approximately 4.33):
Monthly income from part-time job = $123/week x 4.33 weeks/month = $532.59 (rounded to the nearest cent)
To calculate Brooke's total monthly income, we add her full-time and part-time job incomes:
Total monthly income = $3,166.67 + $532.59 = $3,699.26 (rounded to the nearest cent)
b) The rent for the new apartment is $975 per month, including utilities. To determine if it falls within the housing guidelines, we need to compare it to a percentage of Brooke's monthly income.
Typically, a common guideline is to spend no more than 30% of your monthly income on housing.
Percentage of monthly income for housing = 30% of total monthly income
= 30/100 x $3,699.26
= $1,109.78 (rounded to the nearest cent)
Since the rent of $975 is lower than the guideline of $1,109.78, if Brooke takes this apartment, it will fall within the housing guidelines.

what is (0.3)0 in binominal distribution
Answer:
When p, the probability of success, is zero in a binomial distribution, the probability of getting exactly k successes in n trials is also zero for all values of k except when k is zero (i.e., when there are no successes).
So, in the case of (0.3)^0, the result would be 1, because any number raised to the power of 0 is equal to 1. Therefore, the probability of getting zero successes in a binomial distribution when the probability of success is 0.3 is 1.

The length of a rectangle is six times its width. If the area of the rectangle is 600 in2, find its perimeter.
The perimeter of the rectangle is 140 inches.
Let's denote the width of the rectangle as w. According to the given information, the length of the rectangle is six times its width, so we can express the length as 6w.
The area of a rectangle is given by the formula A = length × width. Substituting the values we have:
A = (6w) × w
600 = 6w^2
To solve for w, we divide both sides of the equation by 6:
w^2 = 100
Taking the square root of both sides:
w = ±10
Since width cannot be negative in this context, we discard the negative value and consider the positive value, w = 10.
Now that we have the width, we can find the length of the rectangle:
Length = 6w = 6 × 10 = 60
The perimeter of a rectangle is given by the formula P = 2(length + width). Substituting the values:
P = 2(60 + 10)
P = 2(70)
P = 140
Therefore, the perimeter of the rectangle is 140 inches.

Ralph chase plans to sell a piece of property for $145000. He wants the money to be paid off in two ways-short term note at 10% interest and a long term note at 8% interest. Find the amount of each note if the total annual interest paid is $13100.
10%:
8%:
To solve this problem, we can set up a system of equations based on the given information.
Let's assume the amount of money Ralph Chase will receive through the short-term note is represented by "x" and the amount through the long-term note is represented by "y".
According to the problem, the total amount Ralph plans to sell the property for is $145,000. Therefore, we have the equation:
[tex]\displaystyle x+y=145000[/tex] ...(1)
Now let's consider the interest paid annually. The interest paid on the short-term note at 10% is calculated as [tex]\displaystyle 0.10x[/tex], and the interest paid on the long-term note at 8% is [tex]\displaystyle 0.08y[/tex]. The total annual interest paid is given as $13,100. Therefore, we have the equation:
[tex]\displaystyle 0.10x+0.08y=13100[/tex] ...(2)
We now have a system of two equations (1) and (2). We can solve this system to find the values of "x" and "y".
Multiplying equation (2) by 100 to eliminate decimals, we get:
[tex]\displaystyle 10x+8y=1310000[/tex] ...(3)
Now we can solve equations (1) and (3) simultaneously using any method such as substitution or elimination.
Multiplying equation (1) by 10, we get:
[tex]\displaystyle 10x+10y=1450000[/tex] ...(4)
Subtracting equation (3) from equation (4), we can eliminate "x" and solve for "y":
[tex]\displaystyle 2y=140000[/tex]
Dividing both sides by 2, we find:
[tex]\displaystyle y=70000[/tex]
Now substituting the value of "y" back into equation (1), we can solve for "x":
[tex]\displaystyle x+70000=145000[/tex]
Subtracting 70000 from both sides, we have:
[tex]\displaystyle x=75000[/tex]
Therefore, the amount of money Ralph Chase will receive through the short-term note is 75,000 and through the long-term note is $70,000.

The correct answer choice is: A. all three countries had the same population of 7 thousand in the year 2011.
How to solve this system of equations and interpret the answer?Based on the information provided above, the population (y) in the year (x) of the countries listed are approximated by the following system of equations:
-x + 20y = 129
-x + 10y = 59
y = 7
where:
y is in thousands.x = 10 corresponds to 2010.By solving the system of equations simultaneously, we have the following solution:
-x + 20(7) = 129
x = 140 - 129
x = 11
-x + 10(7) = 59
x = 70 - 59
x = 11
Therefore, the system of equations has only one solution (11, 7).

Step-by-step explanation:
Let's revisit the equation and the solution using the values x = -4, 0, and 5.
The given equation is: 5 + x - 12 = x - 7
Let's go through the steps again to solve it:
5 + x - 12 = x - 7
Combine like terms:
x - 7 = x - 7
Now, subtract x from both sides:
x - x - 7 = x - x - 7
Simplify:
-7 = -7
The equation simplifies to -7 = -7, which is true.
Now, let's use the values x = -4, 0, and 5 to verify the solution.
For x = -4:
5 + (-4) - 12 = (-4) - 7
-11 = -11
The equation is satisfied for x = -4.
For x = 0:
5 + 0 - 12 = 0 - 7
-7 = -7
The equation is satisfied for x = 0.
For x = 5:
5 + 5 - 12 = 5 - 7
-2 = -2
The equation is satisfied for x = 5.
Therefore, the solution x = 0 is correct, and it satisfies the equation for the given values. My earlier statement that x = -4 and x = 5 do not satisfy the equation was incorrect. I apologize for the confusion caused.

The domain of f(x) is (0, +∞), and the range is (0, +∞). The graph of the function will have a vertical asymptote at x = 0 and will continuously increase as x approaches positive infinity.
To graph the given logarithmic function f(x) based on the table, we can use the information provided. The table presents pairs of values (x, y), where x represents the input and y represents the output of the function.
From the table, we can observe that the input values (x) are positive and non-zero. This indicates that the domain of the function is x > 0, meaning x is greater than zero. In interval notation, the domain would be written as (0, +∞).
Looking at the output values (y) in the table, we see that they are all positive. This suggests that the range of the function is y > 0, meaning y is greater than zero. In interval notation, the range would be expressed as (0, +∞).
Graphically, the function f(x) is logarithmic and will have a vertical asymptote at x = 0. As x approaches positive infinity, the function increases without bound. The graph starts at y = 125 when x = 1, and it intersects the y-axis at y = 5 when x = 1.5. The graph of the function will resemble a curve that approaches but never touches the x-axis.

[tex]\displaystyle{x^2-1\neq 0}[/tex]
Solve the inequality; factor the expression:
[tex]\displaystyle{(x-1)(x+1) \neq 0}[/tex]
Hence,
[tex]\displaystyle{x \neq 1,-1}[/tex]
Therefore, x = -1, 1 both are not in the domain of h.
Darla, Ellie, and Fran ate a whole container of ice cream. Darla ate half as much as Ellie ate, and Fran ate 5 times as much as Darla ate. If the container of ice cream cost $4.00, how much, in dollars, should each person pay?
Jana entered the following group of values into the TVM Solver of her
graphing calculator. N=48; 1% = 0.6; PV = ; PMT=-290; FV = 0; P/Y = 12; C/Y
= 12; PMT:END. Which of these problems could she be trying to solve?
OA. A person can afford a $290-per-month loan payment. If he is being
offered a 48-year loan with an APR of 7.2%, compounded monthly,
what is the mosioney that he can borrow?
B. A person can afford a $290-per-month loan payment. If he is being
offered a 4-year loan with an APR of 0.6%, compounded monthly,
what is the most money that he can borrow?
C. A person can afford a $290-per-month loan payment. If he is being
offered a 48-year loan with an APR of 0.6%, compounded monthly,
what is the most money that he can borrow?
D. A person can afford a $290-per-month loan payment. If he is being
offered a 4-year loan with an APR of 7.2%, compounded monthly,
what is the most money that he can borrow?
Answer:
Jana is likely trying to solve option B:
"A person can afford a $290-per-month loan payment. If he is being offered a 4-year loan with an APR of 0.6%, compounded monthly, what is the most money that he can borrow?"
Step-by-step explanation:
Option B is the correct choice because it aligns with the values entered by Jana into the TVM Solver. Jana set the loan term (N) to 48, which represents 48 months (4 years). The APR value of 0.6% also matches what Jana inputted.
By selecting option B, Jana is attempting to find out the maximum amount of money she can borrow given that she can afford a $290-per-month loan payment and is offered a 4-year loan with an APR of 0.6%, compounded monthly.
This calculation will help Jana determine the loan amount that corresponds to her desired monthly payment and the given loan terms.

Select the correct answer.
The length, l, of a rectangle is modeled by the equation l = w + 4, where w is the width of the rectangle in centimeters.
Two equations have been determined that represent the area of the rectangle, A, in square centimeters:
The first equation was created using the formula for the area of a rectangle: A = w2 + 4w.
The second equation models the relationship between the rectangle's area and width: A = 4w + 45.
Which statement describes the solution(s) of the system?
A.
There are two solutions, and neither are viable.
B.
There are two solutions, but only one is viable.
C.
There are two solutions, and both are viable.
D.
There is only one solution, and it is viable.
Answer:
B) There are two solutions, but only one is viable.
Step-by-step explanation:
Given system of equations:
[tex]\begin{cases}A=w^2+4w\\A=4w+45\end{cases}[/tex]
To solve the system of equations, substitute the first equation into the second equation:
[tex]w^2+4w=4w+45[/tex]
Solve for w using algebraic operations:
[tex]\begin{aligned}w^2+4w&=4w+45\\w^2+4w-4w&=4w+45-4w\\w^2&=45\\\sqrt{w^2}&=\sqrt{45}\\w&=\pm \sqrt{45}\\w &\approx \pm 6.71\; \sf cm\end{aligned}[/tex]
Therefore, there are two solutions to the given system of equations.
However, as length cannot be negative, the only viable solution is w ≈ 6.71 cm.
