which statement is true about this argument ?
premises:
If a quadrilateral is a square, then the quadrilateral is a rectangle.
If a quadrilateral is a rectangle then the quadrilateral is a parallelogram.

conclusion:
If a quadrilateral is a square, then the quadrilateral is a parallelogram.

A. the argument is not valid because the premises are not true.
B.the argument is valid by the law of syllogism
C. the argument is valid by the law of detachment
D. the argument is not valid because the conclusion does not follow from the premises.

Answers

Answer 1
It's good to review the laws of syllogism and detachment.

Law of detachment:
Statement 1: If p then q.
Statement 2: p is true.
By the law of detachment, you can conclude "q is true."

Law of syllogism:
Statement 1: If p then q.
Statement 2: If q then r.
By the law of syllogism, you can conclude "If p then r."

Now look at which of the two cases above you have.
Statement 1: If a quadrilateral is a square, then the quadrilateral is a rectangle.
This is "if p then q."

Statement 2:
If a quadrilateral is a rectangle then the quadrilateral is a parallelogram.
This is "if q then r."

You have
If p then q.
If q then r.

This is what you need for the law of syllogism.

That means you can conclude "if p then r", which in this specific case is
"If a quadrilateral is a square, then the quadrilateral is a parallelogram."

The answer is that it is a valid argument by the law of syllogism.
Answer 2

The statement that is true about this argument is B. The argument is valid by the law of syllogism.

The law of syllogism means that an argument can be based on deductive reasoning. In such a case, there are premises and a conclusion.

A quadrilateral is a shape that has four sides. Therefore, based on the premises given, a quadrilateral is a square, then the quadrilateral is a parallelogram.

If ABC XYZ, mA = 50°, and mY = 70°, find mC

Answers

if they are congruent, C is 60

Final answer:

Using the properties of congruent triangles and the fact that the sum of the angles in a triangle is 180°, the measure of angle C (mC) is found to be 60°.

Explanation:

Given that triangle ABC is congruent to triangle XYZ, we know that corresponding angles of congruent triangles are equal. Since the measure of angle A (mA) is given as 50°, and in triangle XYZ, the measure of angle Y (mY) is 70°, we can use the fact that the sum of the angles in a triangle is 180° to find the measure of angle C (mC).

The sum of the angles in triangle ABC would be:

mA + mB + mC = 180°

50° + mB + mC = 180°

Since triangle ABC is congruent to triangle XYZ, mB will be equal to mX, which is the same as mY, that is 70°:

50° + 70° + mC = 180°

Now, we just need to subtract the sum of mA and mB from 180° to find mC:

mC = 180° - (50° + 70°)

mC = 180° - 120°

mC = 60°

a.
$37,500
b.
$87,500
c.
$100,000
d.
$125,000

Answers

Final answer:

In order for Mr. Gonzalez to reach his goal of $60,000, if his base salary is $18,000 and he earns a 4% commission on sales, he would need to make about $87,500 in sales per month.

Explanation:

In this question, Mr. Gonzalez has a base salary of $18,000 and wishes to earn a total of $60,000 for the year. This means he needs to earn an additional $42,000 ($60,000 - $18,000) from sales commission.

The commission rate is 4%, which means for every $100 he sells, he earns $4. Therefore, to find out how much he needs to sell to make the required commission, we require to divide the target commission by the commission percentage.

Therefore, he will need to sell $42,000 / 0.04 = $1,050,000 for the whole year. If this is divided evenly over the year for monthly targets, then it would be $1,050,000 / 12 (months), which results in approximately $87,500 per month.

So, the correct answer option should be b. $87,500 per month.

The bedroom of a house is 1,200 cubic meters. We know that there are 3.4 x 109 particles of dust per cubic meter. How many particles of dust are present in the bedroom of the house

Answers

To find the number of dust particles in a 1200 cubic meter bedroom with 3.4 x 10⁹ particles per cubic meter, multiply the volume by the number of particles per volume, resulting in approximately 4.08 trillion dust particles.

To calculate the number of dust particles in the bedroom, we need to multiply the volume of the bedroom by the number of dust particles per cubic meter. Given that the bedroom is 1200 cubic meters and that there are 3.4 x 10⁹ particles of dust per cubic meter, we can use the following calculation:

Number of particles = Volume of the bedroom x Number of particles per cubic meter

Number of particles = 1200 m³ x 3.4 x 10⁹ particles/m3

Number of particles = 4.08 x 10¹² particles

Therefore, there are approximately 4.08 trillion dust particles in the bedroom of the house.

Answers

1)      The domain is every value of x for which f(x) is a real number.

f(x) = 13 / (10-x)
The only x value that would not produce a real number for f(x) is 10, since you cannot divide a number by zero. Answer is C

2)      F(x) =(x-6)(x+6)/(x2  - 9)
The vertical asymptotes are x=3 and x=-3. Graph the function on a graphing calculator to observe the behavior of the function at these points. There is both a positive and negative vertical asymptote a both x=3 and x=-3. Keep in mind that the denominator approaches zero at these points, and thus f(x) approaches either positive or negative infinite, depending on whether the denominator, however small, is a positive or negative number. Answer is B) 3, -3

3)      F(x) = (x2 + 4x-7) / (x-7)
Although there is a vertical asymptote as x=7, there is no horizontal asymptote. This makes sense. As X gets bigger, there is nothing to hold y back from getting greater and greater. X2 is the dominant term, and it’s only in the numerator. A) none

4)      (x2 + 8x -2) / (x-2)
This function is very similar in structure to the previous one. Same rules apply. Dominant term only in the numerator means no horizontal asymptote. A)None

5)      Our function approaches 0 as x approaches infinite, and has a vertical asymptote at x=2 and x=1.
Here’s an easy example: 10 / ((x-2)*(x-1)). At x=2 and x=1, there is both a positive and negative vertical asymptote. As x approaches infinite, the numerator is dominated by the denominator, which contains x (actually x2 ), and thus y approaches zero.  

1. Considering f(x) = [tex] \frac{13}{10-x} [/tex]
c) All real numbers except 10
Compare the denominator to zero and it will give you the point where there is no f(x) because it is impossible to divide anything by 0.
10-x=0 ⇔ x=10
The function has a domain containing all real numbers except 10 → x<10 or x<10.

2. Considering f(x)=[tex] \frac{(x-6)(x+6)}{x^{2}-9 } [/tex]
b) x = 3, x = -3
Once more, compare the denominator to zero and it will give you the point/points where there is no f(x) because it is impossible to divide anything by 0, and there is where you can find the vertical asymptotes. 
x²-9=0 ⇔ x=-3, x=3
The vertical asymptotes are x=3 and x=-3.

3. Considering [tex] \frac{x^{2}+4x-7}{x-7} [/tex]
a) None (of those presented)
Apply long division on the function. 
The horizontal asymptote is y=x+11.

4. Considering [tex] \frac{x^{2}+8x-2}{x-2} [/tex]
a) None (of those presented)
Once more, apply long division on the function.
The horizontal asymptote is y=x+10.

5. The polynomial in the numerator has to have a smaller degree than the polynomial in the denominator. The polynomial in the denominator needs to have factors of x-1 and x-2. This factors should not be part of the polynomial in the numerator. An example of such a function could be: f(x)=[tex] \frac{8x-2}{ x^{2} -3x+2} [/tex]

Carrie is an American teaching English in Mexico, and she currently has 45,000 pesos in her bank account. If the exchange rate changes from 1 U.S. dollar = 12.94 Mexican pesos to 1 U.S. dollar = 13.09 Mexican pesos, what happens to the value in U.S. dollars of the money in Carrie's bank account?

Answers

it decreases by 39.85

Answer:

Because of change in conversion rates, the value in Carrie's account decreases by $39.85.

Step-by-step explanation:

Total money in Carrie's bank account = 45000 pesos.

If exchange rate is 1 USD = 12.94 pesos, then in dollars the money in account is :

[tex]\frac{45000}{12.94}[/tex] = $3477.588 ≈ $3477.59

If exchange rate is 1 USD = 13.09 pesos, then in dollars the money in account is :

[tex]\frac{45000}{13.09}[/tex] = $3437.738 ≈ $3437.74

Now, if the conversion rate is 12.94 pesos then the amount in dollars is more, than when the conversion rate is 13.09 pesos.

The difference is [tex]3477.59-3437.74=39.85[/tex] dollars.

So, because of change in conversion rates, the value in Carrie's account decreases by $39.85.

The number of bacteria's in petri dish 'A' are 30 times more than the bacteria's in petri dish 'B'.

What is bacteria?

Bacteria are small single-celled organisms. Bacteria are found almost everywhere on Earth and are vital to the planet's ecosystems.

Given is a culture of 2.4 × 10¹¹ bacteria is in petri dish 'A' and a culture of

8 × 10⁹ bacteria is in petri dish B.

Number of bacteria's in petri dish A = n[A] = 2.4 × 10¹¹ bacteria

Number of bacteria's in petri dish B = n[B] = 8 × 10⁹ bacteria

For comparison, lets assume that -

k = n[A]/n[B]

k = 2.4 × 10¹¹ / 8 × 10⁹

k = 240 / 8

k = 30

n[A] = 30 n[B]

What is the value of the expression when n=3?

–2n(5 + n – 8 – 3n)

Answers

Final answer:

When n=3, the value of the expression is 54.

Explanation:

To find the value of the expression when n=3, we substitute n=3 into the expression: –2n(5 + n – 8 – 3n).

First, we simplify the expression:

–2n(5 + n – 8 – 3n) = –2(3)(5 + 3 – 8 – 3(3))

= –2(3)(5 + 3 – 8 – 9)

= –2(3)(-9)

= –2(-27)

= 54.

Therefore, when n=3, the value of the expression is 54.

Which of the following is a solution of x2 − 6x = –22?
A. -6-i√52
B. -6+i√13
C. 3-i√13
D. -3+i√52

Answers

There are many ways in which we can find for the zeros of the problem. We can use the quadratic formula, completing the square, using a graphing calculator, etc.

For this problem, I'll be completing the square.

x² - 6x = -22

Since the constant has been moved to the right side already, we can move on to the next step which is adding (b/2)² to both sides of the equation.

x² - 6x + (-6/2)² = -22 + (-6/2)²

x² - 6x + 9 = -22 + 9

Factor the left side of the equation into a perfect square and simplify the right side.

(x - 3)(x - 3) = -13

Take the square of both sides.

x - 3 = ± √-13

Take out the negative from the square root as the letter "i"

x - 3 = ± i√13

Add 3 to both sides of the equation to let x be by itself.

x = 3 ± i√13

So your two roots will be:

x = 3 + i√13 and x = 3 - i√13

Solution: C. 3 - i√13
