Therefore, the solution is: p(x) = Neither. r(n) = Odd. q(t) = Even. w(x) = Neither.

a. p(x) = x² +7:

Algebraically, p(x) is neither even nor odd.

Because it does not satisfy the conditions of even and odd functions. To show that, we let p(-x) = f(x)  Where f(x) is the same as p(x).

Then, p(-x) = (-x)² +7 = x² + 7, which is the same as f(x).

Since p(-x) ≠ -p(x) and p(-x) ≠ p(x), then p(x) is neither even nor odd.

Therefore, it is neither.

b. r(n) = n³:

Algebraically, r(n) is an odd function.

We show that by substituting -n for n and simplify.

Then, r(-n) = (-n)³ = -n³ = - r(n).

Therefore, r(n) is odd.

c. q(t)= (t - 3)² +71:

Algebraically, q(t) is even.

We show that by substituting -t for t and simplify.

Then, q(-t) = (-t - 3)² + 71 = (t + 3)² + 71 = q(t).

Therefore, q(t) is even. d. w(x)= x³ + 5x:

Algebraically, w(x) is neither even nor odd. Because it does not satisfy the conditions of even and odd functions.

To show that, we let w(-x) = f(x). Where f(x) is the same as w(x).Then, w(-x) = (-x)³ + 5(-x) = -x³ - 5x.

And f(x) = x³ + 5x. Since w(-x) ≠ -w(x) and w(-x) ≠ w(x), then w(x) is neither even nor odd.

To determine if (p→q)∨(p→r) and p→(q∨r) are logically equivalent, we construct a truth table that considers all possible combinations of truth values for p, q, and r. The truth table will have columns for p, q, r, (p→q), (p→r), (p→q)∨(p→r), and p→(q∨r).

By evaluating the truth values for each combination of p, q, and r and comparing the resulting truth values for (p→q)∨(p→r) and p→(q∨r), we can determine if they are logically equivalent. If the truth values for both statements are the same for every combination, then the statements are logically equivalent.

The displacement x(t) for overdamped oscillations is given by x(t) = (cosh βt + sin βt) [(A + B) cosh ωt + (A - B) sinh ωt].

The correct expression for the displacement x(t) in terms of hyperbolic functions is:

B. x(t) = (cosh βt + sin βt) [(A + B) cosh ωt + (A - B) sinh ωt]

To show this, let's start with the given expression x(t) = e^(-βt) [A e^(ωt) + B e^(-ωt)] and rewrite it in terms of hyperbolic functions.

Using the relationships e^y = cosh(y) + sinh(y) and e^(-y) = cosh(y) - sinh(y), we can rewrite the expression as:

x(t) = [cosh(βt) - sinh(βt)][A e^(ωt) + B e^(-ωt)]

= [cosh(βt) - sinh(βt)][(A e^(ωt) + B e^(-ωt)) / (cosh(ωt) + sinh(ωt))] * (cosh(ωt) + sinh(ωt))

Simplifying further:

x(t) = [cosh(βt) - sinh(βt)][A cosh(ωt) + B sinh(ωt) + A sinh(ωt) + B cosh(ωt)]

= (cosh(βt) - sinh(βt))[(A + B) cosh(ωt) + (A - B) sinh(ωt)]

Comparing this with the given options, we can see that the correct expression is:

B. x(t) = (cosh βt + sin βt) [(A + B) cosh ωt + (A - B) sinh ωt]

Therefore, option B is the correct answer.

From the given information, we can conclude that option B) Brown and green snakes will generally be faster than black snakes.

The statement "All of the green snakes are faster than most of the black snakes" implies that there is a significant overlap in the speed range of green snakes and black snakes.

However, it does not specify if all green snakes are faster than all black snakes, leaving room for some slower green snakes compared to faster black snakes.

Therefore, we cannot conclude option A) The range of speed was largest amongst the green snakes.

The statement "All of the brown snakes are faster than all of the green snakes" implies that the brown snakes have a higher speed than the green snakes, without any overlap in their speed range.

Since the green snakes are faster than most of the black snakes, and the brown snakes are faster than all of the green snakes, it can be inferred that both brown and green snakes will generally be faster than black snakes. This supports option B).

There is no information provided about the average speeds of the snakes, so we cannot conclude option C) The average speed of black snakes is faster than the average of green snakes.

Similarly, there is no information given regarding the range of speeds amongst black snakes, so we cannot conclude option D) The range of speeds amongst green snakes is larger than the range of speeds amongst black snakes.

The exact value of cos(105°) + cos(15°) can be determined using trigonometric identities. It simplifies to 0.

We can use the cosine sum formula, which states that cos(A + B) = cos(A)cos(B) - sin(A)sin(B). Applying this formula, we have:

cos(105°) + cos(15°) = cos(90° + 15°) + cos(15°)

                = cos(90°)cos(15°) - sin(90°)sin(15°) + cos(15°)

                = 0 * cos(15°) - 1 * sin(15°) + cos(15°)

                = -sin(15°) + cos(15°)

Since the sine and cosine functions of 15° are equal (sin(15°) = cos(15°)), the expression simplifies to:

-sin(15°) + cos(15°) = -1 * sin(15°) + 1 * cos(15°) = 0

The sound of a pin drop is approximately 15 times greater than the threshold sound level.

To determine how many times greater the sound of a pin drop is compared to the threshold sound level, we need to calculate the difference in decibel levels.

The threshold sound level is typically defined as 0 decibels (dB), which represents the faintest sound that can be detected by the human ear. Given that the sound of a pin drop is approximately 15 decibels, we can calculate the difference as follows:

Difference = Pin drop sound level - Threshold sound level

Difference = 15 dB - 0 dB

Difference = 15 dB

Therefore, the sound of a pin drop is 15 times greater than the threshold sound level. Rounded to the nearest whole number, the sound of a pin drop is approximately 15 times greater than the threshold sound level.

The flow rate using a microdrip (megtt) setup would be 780 mL/hr. To calculate the rate at which you will set the pump in question 8, we need to determine the total amount of medication to be infused and the infusion duration.

Given:

Patient's weight = 78 kg

Medication concentration = 5 g in a 0.5 L bag of 0.95% NS

Infusion duration = 90 minutes

Step 1: Calculate the total amount of medication to be infused:

Total amount = Dose per unit area x Patient's body surface area

Patient's body surface area = (height in cm x weight in kg) / 3600

Dose per unit area = 1.8 g/m²/day

Patient's body surface area = (150 cm x 78 kg) / 3600 ≈ 3.25 m²

Total amount = 1.8 g/m²/day x 3.25 m² = 5.85 g

Step 2: Determine the rate of infusion:

Rate of infusion = Total amount / Infusion duration

Rate of infusion = 5.85 g / 90 minutes ≈ 0.065 g/min

Therefore, you would set the pump at a rate of approximately 0.065 g/min.

Now, let's move on to question 9 and calculate the flow rate using a microdrip (megtt) setup.

Given:

Rate of infusion = 0.065 g/min

Medication concentration = 5 g in a 0.5 L bag of 0.9% NS

Step 1: Calculate the flow rate:

Flow rate = Rate of infusion / Medication concentration

Flow rate = 0.065 g/min / 5 g = 0.013 L/min

Step 2: Convert flow rate to mL/hr:

Flow rate in mL/hr = Flow rate in L/min x 60 x 1000

Flow rate in mL/hr = 0.013 L/min x 60 x 1000 = 780 mL/hr

Therefore, the flow rate using a microdrip (megtt) setup would be 780 mL/hr.

In this scenario, a six-sided die is rolled 120 times, and we need to conduct a hypothesis test to determine if the die is fair. We will calculate the expected frequencies for each face value, perform the chi-square goodness-of-fit test, find the test statistic and p-value, and determine whether we reject the null hypothesis at a significance level of 0.05.

a) To calculate the expected frequency, we divide the total number of rolls (120) by the number of faces on the die (6), resulting in an expected frequency of 20 for each face value.

b) The degrees of freedom (df) in this test are equal to the number of categories (number of faces on the die) minus 1. In this case, df = 6 - 1 = 5.

c) To calculate the chi-square test statistic, we use the formula:

χ^2 = Σ((O - E)^2 / E), where O is the observed frequency and E is the expected frequency.

d) Once we have the test statistic, we can find the p-value associated with it. The p-value represents the probability of obtaining a test statistic as extreme as, or more extreme than, the observed value, assuming the null hypothesis is true. We compare this p-value to the chosen significance level (α = 0.05) to determine whether we reject or fail to reject the null hypothesis.

If the p-value is less than 0.05, we reject the null hypothesis, indicating that the die is not fair. If the p-value is greater than or equal to 0.05, we fail to reject the null hypothesis, suggesting that the die is fair.

By following these steps, we can perform the hypothesis test and determine whether the die is fair or not.

The percentage of the tip is 20%.If Daphne left a 20% tip, then the percentage of the tip is 20% of the cost of her meal.

Daphne left a 20% tip. The percentage of the tip is 20%. The cost of Daphne's meal is not provided in the question. However, we can use the fact that the tip is a percentage of the cost of the meal to determine the cost of the meal.

Let C be the cost of Daphne's meal. Then, the tip she left would be 0.20C, since it is 20% of the cost of the meal. Therefore, the total cost of Daphne's meal including the tip would be:C + 0.20C = 1.20C.

We can see from this model that adding the tip and the cost of the meal results in a total cost of 1.20 times the original cost. This means that the tip is 20% of the total cost of the meal plus tip, which is equivalent to 1.20C. We can use the fact that the tip is a percentage of the cost of the meal to determine the cost of the meal.

Penelope would pay a total interest of $3,630 at 5.5% simple interest over 6 years.

At 5.5% simple interest, the total interest Penelope would pay can be calculated using the formula: Total Interest = Principal x Rate x Time

Here, the principal (P) is $11,000, the rate (R) is 5.5% (or 0.055), and the time (T) is 6 years.

Total Interest = $11,000 x 0.055 x 6 = $3,630

Therefore, Penelope would pay a total interest of $3,630 at 5.5% simple interest over 6 years.

In simple interest, the interest remains constant over the loan period, and it is calculated only on the original principal. So, regardless of the time passed, the interest remains the same.

It's worth noting that this calculation assumes that the interest is paid annually and does not take compounding into account.

(a) The falsity of p can be justified by providing evidence or logical reasoning that disproves the statement.(b) The statement is false if there is no integer k that satisfies m = kn - 1. (c) The equation x²= 0 has solutions if and only if x is equal to 0. d)  if p is stated to be prime, it means that p is a positive integer greater than 1 that has no divisors other than 1 and itself.

(a) To determine the falsity of a statement, we need to examine the logical reasoning or evidence provided. If the statement contradicts established facts, theories, or logical principles, then it can be considered false. Justifying the falsity involves presenting arguments or counterexamples that disprove the statement's validity.

(b) When evaluating the truthfulness of the statement "If m is an integer belonging to N with -1 modulo n," we must assess whether there exists an integer k that satisfies the given condition. If we can find at least one counterexample where no such integer k exists, the statement is considered false. Providing a counterexample involves demonstrating specific values for m and n that do not satisfy the equation m = kn - 1, thus disproving the statement.

(c) The equation x^2 = 0 has solutions if and only if x is equal to 0.

To understand this, let's consider the quadratic equation x^2 = 0. To find its solutions, we need to determine the values of x that satisfy the equation.

If we take the square root of both sides of the equation, we get x = sqrt(0). The square root of 0 is 0, so x = 0 is a solution to the equation.

Now, let's examine the "if and only if" statement. It means that the equation x^2 = 0 has solutions only when x is equal to 0, and it has no other solutions. In other words, 0 is the only value that satisfies the equation.

We can verify this by substituting any other value for x into the equation. For example, if we substitute x = 1, we get 1^2 = 1, which does not satisfy the equation x^2 = 0.

Therefore, the equation x^2 = 0 has solutions if and only if x is equal to 0.

(d)When discussing the primality of p, we typically consider its divisibility by other numbers. A prime number has only two divisors, 1 and itself. If any other divisor exists, then p is not prime.

To determine if p is prime, we can check for divisibility by numbers less than p. If we find a divisor other than 1 and p, then p is not prime. On the other hand, if no such divisor is found, then p is considered prime.

To calculate the inverse temperature, follow these three steps:

Step 1: Convert the average temperature from Celsius to Kelvin.

Step 2: Divide 1 by the converted temperature.

Step 3: Round the inverse temperature to the desired precision.

An example of a statement that represents classical probability is the following: "The probability of rolling a fair six-sided die and obtaining a 4 is 1/6."

The statement exemplifies classical probability by considering a fair and equally likely scenario and calculating the probability based on the favorable outcome (rolling a 4) and the total number of outcomes (six).

Classical probability is based on equally likely outcomes in a sample space. It assumes that all outcomes have an equal chance of occurring.

In this example, rolling a fair six-sided die has six possible outcomes: 1, 2, 3, 4, 5, and 6. Each outcome is equally likely to occur since the die is fair.

The statement specifies that the probability of obtaining a 4 is 1/6, which means that out of the six equally likely outcomes, one of them corresponds to rolling a 4.

Classical probability assigns probabilities based on the ratio of favorable outcomes to the total number of possible outcomes, assuming each outcome has an equal chance of occurring.

The value of (-1+√3i)[tex]^12[/tex] is -4096-4096√3i.

To find the value of (-1+√3[tex]i)^12[/tex]using DeMoivre's Theorem, we can follow these steps:

Convert the complex number to polar form.

The given complex number (-1+√3i) can be represented in polar form as r(cosθ + isinθ), where r is the magnitude and θ is the argument. To find r and θ, we can use the formulas:

r = √((-[tex]1)^2[/tex] + (√3[tex])^2[/tex]) = 2

θ = arctan(√3/(-1)) = -π/3

So, (-1+√3i) in polar form is 2(cos(-π/3) + isin(-π/3)).

Apply DeMoivre's Theorem.

DeMoivre's Theorem states that (cosθ + isinθ)^n = cos(nθ) + isin(nθ). We can use this theorem to find the value of our complex number raised to the power of 12.

(cos(-π/3) +[tex]isin(-π/3))^12[/tex] = cos(-12π/3) + isin(-12π/3)

= cos(-4π) + isin(-4π)

= cos(0) + isin(0)

= 1 + 0i

= 1

Step 3: Convert the result back to rectangular form.

Since the result of step 2 is 1, we can convert it back to rectangular form.

1 = 1 + 0i

Therefore, (-1+√3[tex]i)^12[/tex]= -4096 - 4096√3i.

The nature of the data in the table, such as the variables involved and their relationships, is crucial for understanding and visualizing the corresponding graph. Graphs can take various forms, including line graphs, bar graphs, scatter plots, and more, depending on the data being represented.

For example, if the table consists of two columns with numerical values, it may indicate a relationship between two variables, such as time and temperature. In this case, a line graph might be appropriate to show how the temperature changes over time. On the other hand, if the table contains categories or discrete values, a bar graph might be more suitable to compare different quantities or frequencies.

Without specific details about the table's content and structure, it is impossible to generate an accurate graph. Therefore, a specific table of values is needed to determine the corresponding graph accurately.

The distance between the boats after 1 hour is equal to 27.055 miles.

In order to determine the distance between the boats after 1 hour, we would have to apply the law of cosine:

C² = A² + B² - 2(A)(B)cosθ

Where:

A, B, and C represent the side lengths of a triangle.

In one (1) hour, one of the boats traveled 28 miles in the direction N50°E while the other boat traveled 26 miles in te direction S70°E. Therefore, the angle between their directions of travel can be calculated as follows;

θ = 180° - (50° + 70°)

θ = 60°

Now, we can determine the distance between the boats;

C² = 28² +26² -2(28)(26)cos(60°)

C = √732

C = 27.055 miles.

The value of tan^(-1)(tan m) where m=17pi/2 is undefined, In one sentence, the inverse tangent function is undefined when its argument is a multiple of pi plus pi/2.

In more than 100 words, the inverse tangent function is defined as the angle whose tangent is the given number. However, there are infinitely many angles whose tangent is the same number,

so the inverse tangent function is not uniquely defined. In the case of m=17pi/2, the tangent of this angle is 0, and there are infinitely many angles whose tangent is 0. Therefore, the inverse tangent function is undefined for this input.

Here is a Python code that demonstrates this:

Python

import math

def tan_inverse(x):

 return math.atan(x)

m = 17 * math.pi / 2

tan_m = math.tan(m)

tan_inverse_tan_m = tan_inverse(tan_m)

if tan_inverse_tan_m is None:

 print("undefined")

else:

 print(tan_inverse_tan_m)

This code prints the following output:

The quarterly deposit required by the local Dunkin' Donuts franchise to buy a new piece of equipment in 4 years that will cost $81,000 if the fund earns 16% interest is $3,587.63.

Given that a local Dunkin' Donuts franchise must buy a new piece of equipment in 4 years that will cost $81,000. The company is setting up a sinking fund to finance the purchase, and they want to know what will be the quarterly deposit if the fund earns 16% interest.

A sinking fund is an account that helps investors save money over time to meet a specific target amount. It is a means of saving and investing money to meet future needs. The formula for the periodic deposit into a sinking fund is as follows:

[tex]P=\frac{A[(1+r)^n-1]}{r(1+r)^n}$$[/tex]

Where P = periodic deposit,

A = future amount,

r = interest rate, and

n = number of payments per year.

To find the quarterly deposit, we need to find out the periodic deposit (P), and the future amount (A).

Here, the future amount (A) is $81,000 and the interest rate (r) is 16%.

We need to find out the number of quarterly periods as the interest rate is given as 16% per annum. Therefore, the number of periods per quarter would be 16/4 = 4.

So, the future amount after 4 years will be, $81,000. Now, we will use the formula mentioned above to calculate the quarterly deposit.

[tex]P=\frac{81,000[(1+\frac{0.16}{4})^{4*4}-1]}{\frac{0.16}{4}(1+\frac{0.16}{4})^{4*4}}$$[/tex]

[tex]\Rightarrow P=\frac{81,000[(1.04)^{16}-1]}{\frac{0.16}{4}(1.04)^{16}}$$[/tex]

Therefore, the quarterly deposit should be $3,587.63.

Hence, the required answer is $3,587.63.

For a loan amount of $50,000 at an interest rate of 6% compounded quarterly for 3 years, the loan amount at the end of 3 years can be calculated using the formula for compound interest.

In a class of 8 boys and 9 girls, the sample space of selecting two students at random can be determined. The probability of selecting two girls can also be calculated by considering the total number of possible outcomes and the number of favorable outcomes.

To calculate the loan amount at the end of 3 years with quarterly compounding, we can use the compound interest formula: A = P(1 + r/n)^(nt), where A is the loan amount at the end of the period, P is the initial loan amount, r is the interest rate, n is the number of compounding periods per year, and t is the number of years. Plugging in the values, we get A = $50,000(1 + 0.06/4)^(4*3) = $56,504.25. Therefore, the loan amount at the end of 3 years, compounded quarterly, is $56,504.25.

The sample space for selecting two students at random from a class of 8 boys and 9 girls can be determined by considering all possible combinations of two students. Since we are selecting without replacement, the total number of possible outcomes is C(17, 2) = 136. The number of favorable outcomes, i.e., selecting two girls, is C(9, 2) = 36. Therefore, the probability of selecting two girls is 36/136 = 0.2647, or approximately 26.47%.
