Part A.
To find the average rate of change, we must divide the change in y-values by the change in x-values. Then, by means of the given points, we have
\(\text{ rate of change: }\frac{y_2-y_1}{x_2-x_1}=\frac{3-(-11)}{5-(-2)}=\frac{14}{7}=2\)as we can note the rate of change must be equal to the slope of the given line equation, which is the coefficient of the variable x.
Part B
Lets graph the given equation.
By comparing with the given options, the answer is option C.
On the other hand, the function g(x) is defined for all real numbers, then (as we can see on the picture) function is increasing over all real numvbers. Then, the function increases on the interval:
\(x\in(-\infty,\infty)\)The behavior of a line is always the same, this means that the function never decreases. Therefore, the answer to the last question is: None (the function never decreases)

. In a fort, there were provisions for 400 men for 23 weeks. 60 more men joined them. How long will the provisions
last?
The additional 60 men, the provisions will last for approximately 20 weeks.
To determine how long the provisions will last with the additional 60 men, we need to consider the total number of people and the original duration the provisions were meant to last.
Originally, the provisions were intended to sustain 400 men for 23 weeks. This means that the provisions were estimated to be sufficient for a total of 400 * 23 = 9200 person-weeks.
Now, with the additional 60 men, the total number of men becomes 400 + 60 = 460.
To calculate how long the provisions will last with the increased number of men, we divide the total person-weeks by the new number of men:
Provisions last = Total person-weeks / Number of men
= 9200 / 460
≈ 20 weeks (rounded to the nearest whole number)
The additional 60 men will extend the supply's shelf life to around 20 weeks.

Find the distance between the two points in simplest radical form. ( 3 , − 7 ) and ( − 2 , − 2 ) (3,−7) and (−2,−2)
Answer: We can use the distance formula to find the distance between the two points (3, -7) and (-2, -2):
distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
where (x₁, y₁) = (3, -7) and (x₂, y₂) = (-2, -2)
distance = √[(-2 - 3)² + (-2 - (-7))²]
distance = √[(-5)² + (5)²]
distance = √[25 + 25]
distance = √50
Simplifying the radical, we can factor out a perfect square of 25 from 50:
distance = √(25 x 2)
distance = 5√2
Therefore, the distance between the two points in simplest radical form is 5√2 units.

By using graphical method, find optimal solution of the problem max z = 3x + y s.t 2x - y ≤ 5 -x + 3y ≤ 6 x ≥ 0, y ≥ 0
By analyzing the graph and evaluating the objective function at each vertex of the feasible region, we can find the optimal solution, which is the vertex that maximizes the objective function z = 3x + y.
To find the optimal solution of the given problem using the graphical method, we need to plot the feasible region determined by the given constraints and then identify the point within that region that maximizes the objective function.
Let's start by graphing the constraints:
1. Plot the line 2x - y = 5. To do this, find two points on the line by setting x = 0 and solving for y, and setting y = 0 and solving for x. Connect the two points to draw the line.
2. Plot the line -x + 3y = 6 using a similar process.
3. The x-axis and y-axis represent the constraints x ≥ 0 and y ≥ 0, respectively.
Next, identify the feasible region, which is the region where all the constraints are satisfied. This region will be the intersection of the shaded regions determined by each constraint.
Finally, we need to identify the point within the feasible region that maximizes the objective function z = 3x + y. The optimal solution will be the vertex of the feasible region that gives the highest value for the objective function. This can be determined by evaluating the objective function at each vertex and comparing the values.
Note: Without a specific graph or additional information, it is not possible to provide the precise coordinates of the optimal solution in this case.

3/26/2023, 10:00:31 PM
Once upon a time, in a dense forest, there lived different species of monkeys. The monkeys were known for their mischievous nature and their love for playing games. One day, they decided to organize a game of tug-of-war.
The monkeys gathered on either side of a long rope, eager to show off their strength. The bigger and stronger monkeys, like the gorillas and baboons, stood at one end, while the smaller monkeys, like the macaques and tamarins, stood at the other end.
Everyone was excited to start the game, but as soon as it began, it became clear that something was wrong. The larger monkeys easily pulled the smaller ones towards them, causing them to lose the game every time.
The smaller monkeys started complaining, saying that the game was unfair because the bigger monkeys had an advantage over them. But the bigger monkeys simply laughed and said, "Monkeys play by their sizes!"
The smaller monkeys realized that this saying was true. They understood that everyone has their strengths and weaknesses and that they should not try to compete with others who are stronger or more powerful than them. Instead, they decided to play games among themselves, where they could use their own unique skills and abilities to compete fairly.
And so, the monkeys continued to play games and have fun in their own way, without worrying about competing with those who were bigger and stronger. From that day on, they respected each other's differences and played by their own sizes.

3/26/2023, 10:01:10 PM
(a) To calculate the change in length of the rod, we can use the formula:
ΔL = αLΔT
where:
α = coefficient of linear expansion
L = initial length of the rod
ΔT = change in temperature
Substituting the given values, we get:
ΔL = (2.40 ✕ 10^-5 (°C)^-1) x (1.6 m) x (25°C - 0.0°C)
ΔL = 0.0096 m
Converting meters to millimeters, we get:
ΔL = 9.6 mm
Therefore, the change in length of the rod is 9.6 mm.
(b) The rod shrinks with lower temperature.
(c) The absolute value of the fraction by which the rod's length changes between the two temperatures can be calculated using the formula:
ΔL
L0
where:
ΔL = change in length of the rod
L0 = initial length of the rod

3/26/2023, 10:02:05 PM
We can disprove the statement "If power set A = power set B, then A = B" using a counterexample.
Let A = {1}, and B = {2}. Then:
Power set of A = {{}, {1}}
Power set of B = {{}, {2}}
Both power sets have two elements: an empty set and a singleton set. Therefore, power set of A is equal to power set of B.
However, A and B themselves are not equal. A contains the element 1 while B contains the element 2. Therefore, we can say that "power set of A = power set of B" does not imply "A = B".
Hence, the statement "If power set A = power set B, then A = B" is false.

3/26/2023, 10:04:27 PM
To simplify the expression 5(3/10)x - 1/5(x - y), we can first distribute the 5 and the -1/5 to get:
(3/2)x - 1/5x + 1/5y
Then, we can combine like terms by adding the coefficients of x and y:
(3/2 - 1/5)x + (1/5)y
To simplify further, we need to find a common denominator for the fractions:
(15/10 - 2/10)x + (2/10)y
Simplifying the numerators, we get:
(13/10)x + (2/10)y
Finally, we can reduce the fractions by dividing both terms by their greatest common factor (GCF) of 1/10:
(130/100)x + (20/100)y
Simplifying further, we get:
(13/10)x + (1/5)y
Therefore, the simplified expression is (13/10)x + (1/5)y.

Previous question
The limit of each function at the given point i n the question 10 to 14, is explained below.
Limit Of A function:A function may get close to two distinct limits. There are two scenarios: one in which the variable approaches its limit by values larger than the limit, and the other by values smaller than the limit. Although the right- and left-hand limits are present in this scenario, the limit is not defined.
When a variable approaches its limit from the right, the function's right-hand limit is the value that approaches.a
10). The limit of f(z) = Arg z as z approaches Zo = 1 does not exist. This is because the argument function is not continuous at the point z = 1, where there is a branch cut.
11). The limit of f(z) = \((1 - lm z)^{-1}\) as z approaches z0 = -8 does not exist. This is because the function approaches infinity as z approaches -8 from the left, and negative infinity as z approaches -8 from the right.
However, if we consider the limit of f(z) as z approaches z0 = -8 + i from both the left and the right, the limit exists and is equal to 0. This is because in the complex plane, the value of Im z cannot exceed 1, so as z approaches -8 + i, the denominator (1 - Im z) approaches 0, and the function approaches infinity. However, the numerator approaches a finite value of 1, which cancels out the denominator, and the overall limit is equal to 0.
12). The limit of f(z) = (z - 2) log(z - 2) as z approaches z0 = 2 is 0. This is because the term (z - 2) approaches 0 as z approaches 2, and log(z - 2) approaches 0 as well because log(z - 2) is continuous at z = 2. Therefore, the limit is equal to 0.
13). The limit of f(z) = -1/z as z approaches z0 = 0 does not exist. This is because as z approaches 0, the magnitude of 1/z approaches infinity, but the direction of approach depends on which quadrant the limit is approached from. Since the limit does not approach a unique value from all directions, the limit does not exist.
14). The limit of f(z) = 2 + \(2^{1/z}\) as z approaches infinity does not exist. This is because as z approaches infinity, the term \(2^{1/z}\) approaches 1, and the limit approaches 2 + 1 = 3. However, if we approach infinity along the real axis, the limit of \(2^{1/z}\) approaches 1, but if we approach infinity along the imaginary axis, the limit of \(2^{1/z}\) approaches infinity. Therefore, the limit of f(z) does not exist.

The number of students who have a cat is 2 (those who have a dog and a cat) + 3 (those who have a cat but do not have a dog) = 5.
The total number of students in the class is the sum of all four categories: 2 (has a cat and a dog) + 3 (has a cat, does not have a dog) + 12 (does not have a cat, has a dog) + 10 (does not have a cat, does not have a dog) = 27.

x²+6x+8 = x²+2x+4x+8
x(x+2)+4(x+2) = (x+4)(x+2)
Putting numerator back,
\(f(x) = \frac{(x+4)(x+2)}{x+4}\)
Cancelling factor (x+4) from numerator and denominator
\(f(x) = x+2\)
Putting x+2 = 0
\(x +2 = 0\\x = -2\)
range = (-∞,-2)∪(-2,∞) and f(x) ≠ -2

Peanut allergies are becoming increasingly common in Western countries. Some evidence points to the timing of peanuts! first introduction in the diet as an influential factor, raising the question of whether pediatricians should recommend early exposure or avoidance. A study enrolled infants with a diagnosed peanut allergy and randomly assigned them to either completely avoid peanuts or consume peanuts in small amounts regularly until they reached 60 months of age. At the end of the study, 18 of the 51 infants who had avoided peanuts were still allergic to peanuts. In contrast, 5 of the 47 infants who had consumed peanuts were still allergic to peanuts. Do the data indicate that one approach is more beneficial? Follow the four‑step process.
STATE: What is the question we are asking?
A. Does early exposure to peanuts better reduce peanut allergy in children with a known allergy to peanuts?
B. Does early exposure to peanuts in small amounts or complete avoidance of peanuts better reduce peanut allergy in children with a known allergy to peanuts?
C. Should all children under the age of 60 months avoid peanuts or only eat them in small amounts?
D. Should all children under 60 months eat peanuts regularly in small amounts?
Answer:
B. Does early exposure to peanuts in small amounts or complete avoidance of peanuts better reduce peanut allergy in children with a known allergy to peanuts?
Step-by-step explanation:
Remember we are told there's already a question whether pediatricians should recommend early exposure or avoidance. Thus, the research question should answer these two issues (early exposure or avoidance).
Hence, the question we are asking is: Does early exposure to peanuts in small amounts or complete avoidance of peanuts better reduce peanut allergy in children with a known allergy to peanuts?

Solve this equation.
Answer:
\(\dfrac{4a^6b^5}{c^3}\)
Step-by-step explanation:
Given expression:
\(\dfrac{8a^4b^{-3}c^{12}}{2a^{-2}b^{-8}c^{15}}\)
Separate like terms:
\(\dfrac{8}{2} \cdot \dfrac{a^4}{a^{-2}}\cdot \dfrac{b^{-3}}{b^{-8}} \cdot \dfrac{c^{12}}{c^{15}}\)
Divide the numbers:
\(4\cdot \dfrac{a^4}{a^{-2}}\cdot \dfrac{b^{-3}}{b^{-8}} \cdot \dfrac{c^{12}}{c^{15}}\)
\(\textsf{Apply the exponent rule} \quad \dfrac{a^b}{a^c}=a^{b-c}:\)
\(4 \cdot a^{4-(-2)} \cdot b^{-3-(-8)} \cdot c^{12-15}\)
Simplify the exponents:
\(4 \cdot a^6 \cdot b^5 \cdot c^{-3}\)
\(\textsf{Apply the exponent rule} \quad a^{-n}=\dfrac{1}{a^n}:\)
\(4 \cdot a^6 \cdot b^5 \cdot \dfrac{1}{c^3}\)
Simplify:
\(\dfrac{4a^6b^5}{c^3}\)
