The rule states that if a statement is true of an arbitrary object, then it is true of all objects.

An axiomatization by using and adding a rule of universal generalization is as follows:((∀1∀1) ∀x A→A(y/x) ∀x A→A(y/x), provided yy is free for xx in AA). Axiomatization in a theory is to provide a precise description of the objects, properties, and relationships that are meaningful in the field of study that the theory belongs to. In addition to the axioms, a formal theory may also specify certain rules of inference that allow us to derive new statements from old ones.

The addition of a rule of universal generalization to the system of axioms and rules of inference allows us to infer statements about all objects in a domain from statements about individual objects.  The generalization rule is as follows: If AA is any statement and xx is any variable, then ∀x A is also a statement. The variable xx is said to be bound by the universal quantifier ∀x. The quantifier ∀x binds the variable xx in statement A to the left of it.

The constant of variation is -4/5.

Suppose y varies directly with x, and y=-4 when x=5. What is the constant of variation?

Suppose y varies directly with x. The formula for direct variation is:

y = kx

where

k is the constant of variation.

If y = -4 when x = 5, then we can substitute these values into the formula and solve for k as follows:-

4 = k(5)

Divide both sides by 5 to isolate k:

k = -4/5

Therefore, the constant of variation is -4/5.

Another way to check if the variation is direct is to use a ratio of the two sets of variables given: If the ratio is always the same, the variation is direct. Here is an example with the values given:

y1 / x1 = y2 / x2

where

y1 = -4, x1 = 5,

y2 = y, and

x2 = x.

Substitute the values and simplify:

y1 / x1 = y2 / x2(-4) / 5 = y / xy = (-4 / 5) x

Hence, the constant of variation is -4/5.

The given second-order differential equation is:

y'' − 3y' + 2y = 0

To solve this differential equation, we will first find its characteristic equation by assuming a solution of the form y = e^(rx), where r is a constant. Substituting this into the differential equation, we get:

r²e^(rx) − 3re^(rx) + 2e^(rx) = 0

Factoring out e^(rx), we have:

For this equation to hold true for all values of x, the term in the parentheses must be equal to zero:

r² − 3r + 2 = 0

We can factorize this quadratic equation:

(r - 1)(r - 2) = 0

Setting each factor to zero, we find the roots of the characteristic equation:

r = 1 and r = 2

Therefore, the general solution of the given second-order differential equation is:

The numerical value of x in the measure of the vertical angles is 16.

Vertical angles are simply angles which are opposite of one another when two lines cross.

Vertical angles have the same angle measure, hence, they are congruent.

From the diagram, as the two lines crosses, the two angles are opposite of each other, hence the angles are vertical angles.

Angle 1 = 65 degrees

Angle 2 = ( 4x + 1 ) degrees

Since vertical angles are congruent.

Angle 1 = Angle 2

Hence:

65 = ( 4x + 1 )

To prove that if each of a, b, and c are relatively prime to n, then the product abc is also relatively prime to n, we can use the property that the greatest common divisor (gcd) of two numbers remains the same if one of the numbers is multiplied by a constant.

Let's assume that gcd(a, n) = gcd(b, n) = gcd(c, n) = 1. This means that a, b, and c are all relatively prime to n.
We want to show that gcd(abc, n) = 1.
To do this, we can use the fact that gcd(a, n) = gcd(b, n) = gcd(c, n) = 1. This implies that there exist integers x, y, and z such that ax + ny = 1, bx + ny = 1, and cx + nz = 1.

Now, let's multiply these equations together:
(ax + ny)(bx + ny)(cx + nz) = 1 * 1 * 1

Expanding this expression, we get:
abxcx + abxnz + axnycx + axnynz + nybxcx + nybxnz + nyanycx + nyanynz = 1

Simplifying further, we obtain:
abc(xcx) + ab(nzx) + a(nycx) + a(nynz) + b(nycx) + b(nynz) + n(ybxcx) + n(ybxnz) + n(yanycx) + n(yanynz) = 1

Notice that each term in this equation has at least one factor of n. Therefore, we can rewrite it as:
n[abc(xcx) + ab(nzx) + a(nycx) + a(nynz) + b(nycx) + b(nynz) + ybxcx + ybxnz + yanycx + yanynz] + abc(xcx) + ab(nzx) + a(nycx) + a(nynz) + b(nycx) + b(nynz) + ybxcx + ybxnz + yanycx + yanynz = 1

The left side of the equation contains n as a factor, so the right side must also contain n as a factor. However, the right side is equal to 1, which is not divisible by n. Therefore, the only possibility is that the coefficient of n on the left side is 0:
abc(xcx) + ab(nzx) + a(nycx) + a(nynz) + b(nycx) + b(nynz) + ybxcx + ybxnz + yanycx + yanynz = 0

This implies that abc is relatively prime to n, as gcd(abc, n) = 1.
Therefore, we have proven that if gcd(a, n) = gcd(b, n) = gcd(c, n) = 1, then gcd(abc, n) = 1.

We have proved that the characteristic spaces associated with different characteristic values are orthogonal.

Given,V is an inner product vector space of finite dimension over C, and there is a self-adjoint linear operator Ton V.

The goal is to prove that the characteristic spaces associated with different characteristic values are orthogonal.

Solution:

Let's suppose λ1 and λ2 are two different eigenvalues of T.

Also, let u1 and u2 be the corresponding eigenvectors. That is,

Tu1 = λ1 u1 and Tu2 = λ2 u2.

Now let's prove that the characteristic spaces corresponding to λ1 and λ2 are orthogonal.

That is,

S(λ1) ⊥ S(λ2)

Let v be an arbitrary vector in S(λ1). That is,Tv = λ1 v

Now we need to show that v is orthogonal to every vector in S(λ2).

Let w be an arbitrary vector in S(λ2). That is,Tw = λ2 w

Taking the inner product of these equations with v, we get:

(Tv, w) = λ2(v, w)    [Since v is in S(λ1) and w is in S(λ2), they are orthogonal]

Now, substituting the values of Tv and Tw in the above equation, we get:

λ1(v, w) = λ2(v, w)

As λ1 and λ2 are different eigenvalues, (λ1 - λ2) ≠ 0.

So we can divide both sides by (λ1 - λ2). Thus,(v, w) = 0

Since w was arbitrary in S(λ2), we can conclude that v is orthogonal to every vector in S(λ2).

That is,S(λ1) ⊥ S(λ2)

Thus, we have proved that the characteristic spaces associated with different characteristic values are orthogonal.

The unique solution to the initial value problem is: y = 1 + x + 6x².

To solve the non-homogeneous problem y" = 12(2x²), let's go through the steps:

1) Homogeneous problem:

The homogeneous equation is y" = 0. The auxiliary equation is ar² + br + c = 0.

2) The roots of the auxiliary equation:

Since the coefficient of the y" term is 0, the auxiliary equation simplifies to just c = 0. Therefore, the root of the auxiliary equation is r = 0.

3) Fundamental set of solutions:

For the homogeneous problem y" = 0, since we have a repeated root r = 0, the fundamental set of solutions is Y₁ = 1 and Y₂ = x. So the complementary solution is Yc = C₁(1) + C₂(x) = C₁ + C₂x, where C₁ and C₂ are arbitrary constants.

4) Particular solution:

To find a particular solution, we can use the method of undetermined coefficients. Since the non-homogeneous term is 12(2x²), we assume a particular solution of the form yp = Ax² + Bx + C, where A, B, and C are constants to be determined.

Taking the derivatives of yp, we have:

yp' = 2Ax + B,

yp" = 2A.

Substituting these into the non-homogeneous equation, we get:

2A = 12(2x²),

A = 12x² / 2,

A = 6x².

Therefore, the particular solution is yp = 6x².

5) General solution and initial value problem:

The general solution is the sum of the complementary solution and the particular solution:

y = Yc + yp = C₁ + C₂x + 6x².

To solve the initial value problem y(0) = 1 and y'(0) = 1, we substitute the initial conditions into the general solution:

y(0) = C₁ + C₂(0) + 6(0)² = C₁ = 1,

y'(0) = C₂ + 12(0) = C₂ = 1.

Therefore, the unique solution to the initial value problem is:

Step-by-step explanation:

let x = missing exponent

x - 2 + 1 = 4

x -1 = 4

x = 5

Part 1: The solution to the inequality -3(x - 2) ≤ 0 is x ≥ 2.

Part 2: The solution to the inequality is any value of x that is greater than or equal to 2.

Part 3: Verifying the solution, we substitute x = 2 and x = 3 into the original inequality and find that both values satisfy the inequality.

Part 1:

To solve the inequality -3(x - 2) ≤ 0, we need to isolate the variable x.

-3(x - 2) ≤ 0

Distribute the -3:

-3x + 6 ≤ 0

To isolate x, we'll subtract 6 from both sides:

-3x ≤ -6

Next, divide both sides by -3. Remember that when dividing or multiplying by a negative number, we flip the inequality sign:

x ≥ 2

Therefore, the solution to the inequality is x ≥ 2.

Part 2:

A verbal statement describing the solution to the inequality is: "The solution to the inequality is any value of x that is greater than or equal to 2."

Part 3:

To verify the solution, we can substitute two elements of the solution set into the original inequality and check if the inequality holds true.

Let's substitute x = 2 into the inequality:

-3(2 - 2) ≤ 0

-3(0) ≤ 0

0 ≤ 0

The inequality holds true.

Now, let's substitute x = 3 into the inequality:

The values of x and y in the given system of equations are x = 4.00 and y = 5.00. These values are obtained by solving the system using the method of substitution.

The given system of linear equations is:

0.50x + 0.20y = 3.00 ...(Equation 1)

x + y = 9.00 ...(Equation 2)

To solve this system of equations, we can use the method of substitution or elimination. Let's solve it using the method of substitution:

From Equation 2, we can express x in terms of y:

x = 9.00 - y

Substituting this expression for x in Equation 1, we have:

0.50(9.00 - y) + 0.20y = 3.00

Expanding and simplifying:

4.50 - 0.50y + 0.20y = 3.00

-0.30y = -1.50

Dividing both sides by -0.30:

y = -1.50 / -0.30

y = 5.00

Now, substitute this value of y back into Equation 2 to find x:

x + 5.00 = 9.00

x = 9.00 - 5.00

x = 4.00

To solve for m in the equation 5am = 15, we can isolate the variable m by dividing both sides of the equation by 5a:

5am = 15

Divide both sides by 5a:

(5am)/(5a) = 15/(5a)

Simplify:

m = 15/(5a)

Therefore, the solution for m is m = 15/(5a).

The average angular speed of the hand is ω = 1800 / t rad/s and 103140 / t degrees/s and the average linear speed of the hand is 5D / t m/s.  The answers to A and B are not the same as they refer to different quantities with different units and different values.

A) To find the average angular speed of the hand, we need to use the formula:

angular speed (ω) = (angular displacement (θ) /time taken(t))

= 5 × 360 / t

Here, t is the time for 5 rotations

So, average angular speed of the hand is ω = 1800 / trad/s

To convert this into degrees/s, we can use the conversion:

1 rad/s = 57.3 degrees/s

Therefore, ω in degrees/s = (ω in rad/s) × 57.3

= (1800 / t) × 57.3

= 103140 / t degrees/s

B) To find the average linear speed of the hand, we need to use the formula:linear speed (v) = distance (d) /time taken(t)

Here, the distance of the hand is the length of the arm.

Distance from shoulder to middle of hand = D

Similarly, the time taken to complete 5 rotations is t

Thus, the total distance covered by the hand in 5 rotations is D × 5

Therefore, average linear speed of the hand = (D × 5) / t

= 5D / t

= 5 × distance of hand / time for 5 rotations

C) No, the answers to A and B are not the same. This is because angular speed and linear speed are different quantities. Angular speed refers to the rate of change of angular displacement with respect to time whereas linear speed refers to the rate of change of linear displacement with respect to time. Therefore, they have different units and different values.

The given compound logical proposition is a tautology.

To prove that the given compound logical proposition is a tautology, we need to show that it is always true regardless of the truth values of its individual propositions.

The given compound proposition is:

(asp) →→→ (r^-p)

Let's break it down and analyze it step by step:

The expression "asp" represents the conjunction of the propositions "a" and "sp". We don't have the exact definitions of "a" and "sp," so we cannot make any specific deductions about them.

The expression "(r^-p)" represents the implication of "r" and the negation of "p". This means that if "r" is true, then "p" must be false.

Now, let's consider different scenarios:

Scenario 1: If "r" is true:

In this case, "(r^-p)" is true because if "r" is true, then "p" must be false. Therefore, the compound proposition evaluates to true, regardless of the truth values of "asp".

Scenario 2: If "r" is false:

In this case, "(r^-p)" is also true because the implication "r → ¬p" is true when the antecedent is false. Again, the compound proposition evaluates to true, regardless of the truth values of "asp".

Since the compound proposition is true in both scenarios, regardless of the truth values of its individual propositions, we can conclude that it is a tautology.

Note: It's important to have the exact definitions of the individual propositions and their logical relationships to provide a more precise analysis.

The correct answer is d) 2π / 5.

The period of a Ferris wheel is the time it takes to complete one full revolution or loop.

In this case, the Ferris wheel made 5 loops in a total time of 12 seconds.

To find the period, we need to divide the total time by the number of loops. In this case, 12 seconds divided by 5 loops gives us a period of 2.4 seconds per loop.

However, the question asks for the period, k, in terms of π. To convert the period to π, we divide the period (2.4 seconds) by the value of π.

So, k = 2.4 / π.

Now, we need to find the answer choice that matches the value of k.

Therefore, the correct answer is d) 2π / 5.

The probability of rolling a 6 on a 6-sided die is 1/6.

Rolling a 6-sided die gives us six possible outcomes: 1, 2, 3, 4, 5, or 6. Since we're interested in the event of rolling a 6, there is only one favorable outcome, which is rolling a 6. The total number of outcomes is six (one for each face of the die). Therefore, the probability of rolling a 6 is calculated by dividing the number of favorable outcomes (1) by the total number of outcomes (6), resulting in 1/6.

Probability is a measure of how likely an event is to occur. In this case, we have a fair 6-sided die, which means each face has an equal chance of landing face-up. The probability of rolling a specific number, such as 6, is determined by dividing the number of ways that event can occur (1 in this case) by the total number of equally likely outcomes (6 in this case). So, in a single roll of the die, there is a 1/6 chance of rolling a 6.
