What is Integer?

A zero, a positive natural number, or a negative integer with a minus sign is an integer. The negative numbers are the additive inverses of their positive counterparts.

1.(a) ∃x∀y(y > x)

The statement is False

it is impossible to find a single integer x that has the property that all integer y are bigger that it. for any integer x, the integer y =x-1 is smaller

(b) ∀y∃x(y > x)

the statement is true for every integer y, we can find a integer x that is smaller, for example x=y-1

(c) ∃x(x = 0 → x = 1)

The statement is True

there exist x such that (x = 0, x=1). in this statement when we select x =1. this statement is true  regardless of x not equal to 0 therefore this statement is true if x=1 when x=1

2. (a) ∀x∃y(2 < x ≤ y)

we know

∀xP(x)=∃y(P(x))

∃xP(x)=∃y(P(x))

now apply de morgan law

∃x∀(y)=2>x v x>y

(b) ∀y∃x(y > 0 → x ≤ 0)

we know that A-B = A V B

∀y∃x (Y<0 V X< 0)

∀y∃x (Y<0 : X< 0)

3.(a) Given : All people weigh at least 100 pounds.

The negation is : Some people weigh less than 100 pounds. ( All negates to some, at least negates to less than )

(b) The statement is : Somebody did not see any animals in the zoo.

Equivalently : Somebody see no animals in the zoo.

Negation : Everybody saw some animals in the zoo. ( Somebody negates to everybody, No animals negates to some animals )

4. P(x,y): x is friends with y.

Then the given translates to " For all x there is a person y and a person z such that if y and z are not the same people that x and y are friends and x and z are friends."

The given statement is False. For every person x, we can always find two distinct persons y and z such that x is friends with y and y is friends with z. But, we reach a contradiction when we consider the case when x has only one friend. Then for that particular person x, we can find a person y such that P(x,y) but we cannot find a person z such that P(x,z). Hence, in that case, the statement is FALSE.

Answer:

It can sometimes be equal to π. However, it is equal to our central angle.

Step-by-step explanation:

First, recall that arc length is given by:

\(s=r\theta\)

Where s is the arc length, r is the radius, and θ is the central angle of the arc in radians.

So, the ratio of the arc length to the radius is:

\(\displaystyle \frac{r\theta}{r}\)

The radius r cancels. Hence, we are left with:

\(=\theta\)

So, the ratio of the arc length to the radius does not equal π (although it can sometimes if the central angle is π radians (or 180°)). Rather, the ratio is equivalent to the central angle.

So, for example, if we have a circle with radius 7 with a central angle of 3π/2 (this gives us an arc length of 21π/2), then the ratio of the arc length to the radius will be 3π/2 (our central angle).

Answer:

Sometimes it can be equal to π. It is equal to our central angle.

Step-by-step explanation:

Recalling arc length is given by:

Where s is the arc length, r is the radius, and θ is the central angle of the arc in radians.

So, the ratio of the arc length to the radius is:

rθ/θ

The radius r cancels. Hence, we are left with:

= θ

The asymptotes for the given function are y = 1 and x = 4 respectively.

An asymptote to any function can be defined as a line that touches the graph of the function as the coordinates of the graph approaches infinity.

\(\lim_{x \to \infty}\)The given function is R(x) = (x² - 25)/(x² - 8x + 16)

Since, the given function is not defined at  x² - 8x + 16 = 0.

The values of x can be found as below,

x² - 8x + 16 = 0

⇒ (x - 4)² = 0

⇒ x = 4

Now, \(\lim_{x \to \ 4}} R(x)\) = \(\lim_{x \to \ 4}\) (x² - 25)/(x² - 8x + 16)

                              = -9/0

                              = -∞

Hence, at x = 4 the function has a y asymptote.

Again, in order to find x asymptotes compute the following limit,

\(\lim_{x \to \infty} R(x)\) = \(\lim_{x \to \infty}\) (x² - 25)/(x² - 8x + 16)

Apply L' Hospital rule to get,

\(\lim_{x \to \infty}\) (x² - 25)/(x² - 8x + 16) =  \(\lim_{x \to \infty}\) 2x/ (2x - 8)

⇒ \(\lim_{x \to \infty}\) 2/2 = 1

Thus, the x asymptote of the function is at y = 1.

Hence, the horizontal and vertical asymptotes of the given function are  y = 1 and x = 4 respectively.

The distance in the east direction Mr. Jackamonis after Ms Follis walks 5 feet directly north and the distance between them is 13 feet, obtained using Pythagorean Theorem is 12 feet

Pythagorean Theorem states that the square of the length of the hypotenuse side of a right triangle is equivalent to the sum of the squares of the lengths of the other two sides of the right triangle.

Let a represent the length of the hypotenuse side, and let b and c represent the lengths of the other two sides, then according to the Pythagorean Theorem, we get;

a² = b² + c²

The direction Ms. Follis walks = 5 feet directly north

The direction Mr. Jackamonis walks = Directly east

The distance between Ms. Follis and Mr. Jackamonis = 13 feet apart

The distance Mr. Jackamonis walks, d, can  be found using Pythagorean Theorem as follows;

13² = 5² + d²

Therefore;

d² = 13² - 5² = 144

d = √(144) = 12

d = ± 12

The work done in pumping the entire contents of the fuel tank into the tractor is 7,021,796 joules.

What is volume of cylinder?

The volume of a cylinder V = πr²h where r is the radius of the tank and h is the height of the tank.

Here given that r = 1.5 meters and h = 3 meters, so:

V = π(1.5)²(3) = 21.2 cubic meters

Next, we can calculate the weight of the gasoline using its density and volume,

W = ρVg

where ρ is the density of gasoline (6600 N/m³), g is the acceleration due to gravity (9.81 m/s²), and W is the weight of the gasoline.

So,

W = (6600)(21.2)(9.81) = 1,404,359.2 newtons

Now we can calculate the work done in lifting this weight from the level of the truck bed to the level of the tractor tank opening. This is given by

Work = Force x Distance

where Force is the weight of the gasoline, and Distance is the vertical distance it is lifted.

The distance is given as 5 meters in the problem,

Work = 1,404,359.2 x 5 = 7,021,796 joules

Therefore, the work done in pumping the entire contents of the fuel tank into the tractor is 7,021,796 joules.

The total cost of Kayla's purchase of 0.1 pounds of medium binder clips and 0.2 pounds of jumbo binder clips is $1.20.

To calculate the total cost, we need to determine the cost of each type of binder clip separately and then sum them up.

The cost of medium binder clips is $5 per pound, and Kayla purchased 0.1 pounds. Therefore, the cost of medium binder clips is 0.1 pounds * $5 per pound = $0.50.

The cost of jumbo binder clips is $6 per pound, and Kayla purchased 0.2 pounds. Thus, the cost of jumbo binder clips is 0.2 pounds * $6 per pound = $1.20.

Finally, to find the total cost, we add the individual costs together: $0.50 + $1.20 = $1.70.

Therefore, the total cost of Kayla's purchase of 0.1 pounds of medium binder clips and 0.2 pounds of jumbo binder clips is $1.70.

Step-by-step explanation:

The truth table shows that whenever the premises (P1 and P2) are true, the conclusion (C) is also true. Therefore, the argument form is valid.

To determine the validity of the argument form, we can construct a truth table that includes columns for the premises and the conclusion.Let's assign truth values to the propositions x, y, and z, and evaluate the truth values of the premises and the conclusion based on the given argument form.

Premises:

P1: x → y

P2: y → z

Conclusion:

C: x → z

Here's the truth table:

x y z P1 (x → y) P2 (y → z) C (x → z)

T T T T T T

T T F T F F

T F T F T T

T F F F T F

F T T T T T

F T F T F T

F F T T T T

F F F T T T

In the truth table, we evaluate the truth values of the premises and the conclusion for all possible combinations of truth values for x, y, and z.

For the argument form to be valid, whenever the premises are true, the conclusion must also be true for all possible combinations. In other words, if we have a row where all premises are true, the conclusion must also be true in that row.

From the truth table, we can see that in every row where both premises (P1 and P2) are true, the conclusion (C) is also true. Therefore, the argument form is valid because the conclusion follows logically from the premises in all possible cases.

This demonstrates that the truth table supports the validity of the argument form.

The sequence's numbers are all multiples of 30. Every number can be divided by 30.

If two integers are divided equally, leaving no remainder, then we say that one integer divides the other (we sometimes say, "with no remainder," but that is not technically correct). Mathematicians express this more explicitly as follows: If a and b are integers (with a not zero), then a divides b if c is an integer such that b = ac. Sequence: 1 51, 2 52,....., n 5n,....n 5n=n(n 4 1)=n(n1)(n1)(n+1)(n 2 +1)

The set of possible values for c that gives equations with no real solutions for x is (10, 20, 30), which is option D.

We can solve for x in terms of c by first rearranging the equation:

4x² + 12x = -c

4x² + 12x + c = 0

We can then use the quadratic formula to find the solutions for x:

x = (-b ± √(b² - 4ac)) / 2a

Here, a = 4, b = 12, and c = c.

Plugging these values into the formula gives:

x = (-12 ± √(12² - 4(4)(c))) / (2(4))

x = (-3 ± √(9 - c)) / 2

For this equation to have no real solutions for x, the discriminant (the expression inside the square root) must be negative:

9 - c < 0

c > 9

Therefore, the set of possible values for c for x is (10, 20, 30), which is option D.

The construction of two congruent angles using a scale and compass can be done by applying the prerequisite knowledge of construction.

What is an angle?

A geometrical figure formed by using two rays, which are known as the sides of angle. These sides share a common vertex. Angle can be of various types including acute, obtuse, reflex,  right, etc.

Explanation of constructing an angle using a scale and compass that is both congruent

Start drawing a line with the scale

Then, using this line or edge of the given angle to construct another corner, with the same vertex, let's call it O

Mark an arc across the sides of the corner using compass

Name the points as A and B, where the arc intersects and extend that arc beyond B

Open the compass to length of AB by setting it to the point B, and then mark an arc that intersects the first arc at point C.

Forthwith, wwe have two congruent components, AB = BC.

As the distance is OA = OB = OC, therefore, ∠AOB and ∠BOC are congruent.

Hence, this is the way of constructing congruent angles using a scale and a compass.
