Two out of the three given existential quantifications are true, while one is false.

In mathematics, quantifiers are used to describe the properties of a set or a domain. One such quantifier is the existential quantifier, which is used to indicate the existence of at least one element in a set that satisfies a given property. In this case, we are interested in finding out which of the given existential quantifications are true, where the domain of x is restricted to positive integers. Let's explore this in more detail.

The domain of x is the set of positive integers, which means that x can only take on values such as 1, 2, 3, 4, and so on. The given existential quantifications are as follows:

∃x(x²=9)

∃x(x+3=5)

∃x(x²=2)

Let's examine each of these in turn.

∃x(x²=9)

This existential quantification is true. To see why, we need to find an integer value of x such that x² equals 9. We can easily see that x=3 satisfies this property, since 3² = 9. As 3 is an integer and satisfies the condition, the statement is true.

∃x(x+3=5)

This existential quantification is also true. We need to find an integer value of x such that x+3 equals 5. This can be easily done by subtracting 3 from both sides of the equation to get x=2. As 2 is an integer and satisfies the condition, the statement is true.

∃x(x²=2)

This existential quantification is false. We need to find an integer value of x such that x² equals 2. However, there is no such integer value of x. This can be proven using the fact that the square of any integer is always a non-negative integer. Therefore, the statement is false.

The burgers is sold each for 3.75 dollars , while the fries is solde for 1.25 dollars each

We would have to solve for the price of each of the items using the simultaneous linear equation method

2 burgers and 3 fries for $11.25

we would have:

Use the elimination method to solve the system of equations:

2 x+ 3 y = 11.25

7 x + 5 y = 32.50

Step 1 - Multiply Equation 1 by 7:

7 * (2x+3y=11.25) --> 14x + 21y = 78.75

Step 2 - Multiply Equation 2 by 2:

2 * (7x+5y=32.50) --> 14x + 10y = 65

Step 3 - s

14x + 21y = 78.75

-(14x + 10y = 65)

------------------------------

21y - 10y = 78.75 - 65

Step 4 - simplify and solve for y:

11y = 13.75

y  = 13.75 / 11

y = 1.25

Step 5 - now that we have solved for y, let's rearrange Equation 1 to solve for x:

2x = 11.25 - 3y

Divide each side by 2

2x / 2 = 11.25 - 3y / 2

x  =  11.25 - 3y / 2

Step 6 - we determined y = 1.25. Plug it into our Rearranged equation 1:

x  =  11.25 - 3(1.25) / 2

x  =  11.25 - 3.75 / 2

x  =  7.5 / 2

x = 3.75

Since x is the burgers which is 3.75 dollars while y is the fries which is 1.25 dollars

Answer: The commutative property of addition states that changing the order of the terms being added does not change the sum. Therefore, we can rearrange the terms in an expression in any order we choose without changing the result.

For example, if we have the expression:

3x + 2y + 4x + 5y

We can use the commutative property of addition to rearrange the terms as:

3x + 4x + 2y + 5y

Then, we can collect the like terms (terms with the same variable and exponent) by combining the coefficients:

7x + 7y

So the simplified expression is 7x + 7y.

Step-by-step explanation:

The area of the triangle will be 1 square foot.

Pythagorean theorem states that in the right angle triangle, the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Calculate the value of x of the small right-angle triangle.

4² = ( 3 + x )² + (2 / 3 )²

16 + 9 + 6x + x² + 4 / 9

7 = x² + 6x + 4 / 9

9x² + 54x - 59 = 0

x = 0.9 ft

The area of the triangle will be calculated as:-

Area = ( 1/2 ) x 3.9 x ( 2 / 3 ) - (1/2 ) x 0.9 x ( 2 / 3 )

Area = ( 1 / 2 x 2 / 3 ) ( 3.9 - 0.9 )

Area = ( 1 / 3 ) x 3

Area = 1 square ft

Therefore, the triangle's area will be one square foot.

The required probability that events A and B both occur is 0.15.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

The probability that events A and B both occur is given by the product of their individual probabilities if they are independent. Independence means that the occurrence of one event does not affect the probability of the other event.

In this case, the probability that events A and B both occur is given by:

0.3 × 0.5 = 0.15

So, the probability that events A and B both occur is 0.15.

It's important to note that without further information, we cannot determine if events A and B are independent. The probabilities of 0.3 and 0.5 are the individual probabilities of each event, but we would need to know if their occurrence affects each other to determine if they are independent.

The perimeter of the rectangular bedroom is: A. 116 feet.

Perimeter of a rectangle = 2(length + width)

To find the perimeter of the rectangular bedroom, we need to calculate the sum of the lengths of its four sides.

Let's start by finding the length of the horizontal sides of the rectangle. The two horizontal sides are defined by the points (21, 18) and (21, −7), which are 25 feet apart in the vertical direction (18 − (−7) = 25). Therefore, the length of each horizontal side is 25 feet.

Next, let's find the length of the vertical sides of the rectangle. The two vertical sides are defined by the points (21, 18) and (−12, 18), which are 33 feet apart in the horizontal direction (21 − (−12) = 33). Therefore, the length of each vertical side is 33 feet.

Now we can add up the four side lengths to get the perimeter:

Perimeter = 2(Length of horizontal sides) + 2(Length of vertical sides)

= 2(25 feet) + 2(33 feet)

= 50 feet + 66 feet

M * [0, 1]T = [-1, 1]

Similarly, for the point (1 + i, i):

M * [1 + i, i]T = [-1 + i, -1 + i]

Therefore, we get the linear mapping:

The distance from the pitching rubber to first base is 98.7ft, B - the distance from the pitching rubber to first base is 96.6ft and C - A pitcher must pivot to face in a 45-degree angle if he is facing home plate.

(a) To find the distance from the pitching rubber to first base, we can use the Pythagorean theorem, since the distance forms the hypotenuse of a right triangle with legs of length 80ft (the length of a side of the square) and 55.5ft (the distance from the pitching rubber to home plate along a diagonal line). Thus, we have:

distance to first base = [tex]\sqrt{ 80^{2} + 55.5^{2}[/tex] =  98.7ft

(b) To find the distance from the pitching rubber to second base, we can use the fact that second base is located at a distance of 80ft from home plate along a line perpendicular to the line connecting the pitching rubber and home plate. Using the Pythagorean theorem, we have:

distance to second base = [tex]\sqrt{55.5^{2} + 80^{2} }[/tex] = 96.6ft

(c) If a pitcher faces home plate, he needs to turn through an angle of 45 degrees to face second base. This is because second base is located at one corner of the square, and the angle formed by the lines connecting the pitching rubber to home plate and second base is a right angle (since the sides of the square are perpendicular).
