(A - B) u (A n B) = A is proved using several properties from Theorem 6.2.2. of Set Identities.

To prove (A - B) u (A n B) = A algebraically, we can use the following steps:

(A - B) u (A n B) // Given

[(A n B) U (A - B)] // Definition of union

[(B n A) U (A - B)] // Commutative law of intersection

[(B U (A - B)) n (A U (A n B))] // Distributive law of union over intersection

[(B U (A n B)') n (A U B)] // Complement law of intersection and De Morgan's law

[(B U (A - B)) n (A U B)] // Complement law of A n B

[(B U (A n B)') n (A U B)] // Definition of A - B

[(B U (A n B)') n (B U A')] // De Morgan's law

[(B n (B U A')) U ((A n B)'' n (B U A'))] // Distributive law of intersection over union

[(B n U) U (Ø n (B U A'))] // Complement law of B U A' and B n (B U A')

B U Ø // Identity law of intersection and complement law of B U A'

B // Identity law of union

Therefore, (A - B) u (A n B) = A is proved. We used several properties from Theorem 6.2.2, including the commutative law of intersection, distributive law of union over intersection, complement law of intersection, De Morgan's law, complement law of A n B, definition of A - B, distributive law of intersection over union, complement law of B U A', and identity law of intersection and union.

Answer: 3

Step-by-step explanation:

The standard notation for a point (also called an ordered pair) is (x, y).

And the standard form of writing a function is:

y = f(x).

Where x is the "input" of the function, and y is the "output" of the function.

Then we can see that in the point (x, y)

The input is the first number, and the output is the second number.

Then for the point (3, 18), the fist number will be the input, then:

In the ordered pair (3, 18), the value that represents the input to a function is  3.

Answer:

9 and 135

Step-by-step explanation:

The GCF is 9, and 135 is divisble by 9. The GCF of a standalone number is itself, and the aforementioned divisibility of 135 by 9 rules 9 as one of the numbers. Since 9 is a multiple of 135, and 9 can multiply to be 135, this makes the second number 135.

To find the y-coordinate of point P on the unit circle, given that its x-coordinate is 5/13, we can utilize the Pythagorean identity for points on the unit circle.

The Pythagorean identity states that for any point (x, y) on the unit circle, the following equation holds true:

x^2 + y^2 = 1

Since we are given the x-coordinate as 5/13, we can substitute this value into the equation and solve for y:

(5/13)^2 + y^2 = 1

25/169 + y^2 = 1

To isolate y^2, we subtract 25/169 from both sides:

y^2 = 1 - 25/169

y^2 = 169/169 - 25/169

y^2 = 144/169

Taking the square root of both sides, we find:

y = ±sqrt(144/169)

Since we are dealing with points on the unit circle, the y-coordinate represents the sine value. Therefore, the y-coordinate of point P is:

y = ±12/13

So, the y-coordinate of point P can be either 12/13 or -12/13.

Answer:

x ≥ 3

Step-by-step explanation:

The value of S, which represents the length of each side of the square, is 4 miles.

To find the value of S, we need to determine the length of each side of the square. Given that the perimeter of the square is 16 miles, we can use the formula for the perimeter of a square, which is 4 times the length of a side.

Perimeter = 4 × S

Given that the perimeter is 16 miles, we can substitute this value into the equation:

16 = 4 × S

To solve for S, we divide both sides of the equation by 4:

16 ÷ 4 = S

4 = S

Therefore, S, which stands for the square's side lengths, has a value of 4 miles.

So, S = 4 miles.

This means that each side of the square measures 4 miles, and the square has equal sides and right angles at each corner.

A type II error is a statistical term used to describe the failure to reject a false null hypothesis. It occurs when the null hypothesis is actually false but is not rejected because the statistical test failed to find significant evidence against it.

In other words, it happens when an alternative hypothesis is true, but we fail to reject the null hypothesis.

Types of errors in hypothesis testing

There are two types of errors in hypothesis testing:

Type I error: Rejecting a true null hypothesis

Type II error: Failing to reject a false null hypothesis.Type I error occurs when a true null hypothesis is rejected while Type II error occurs when a false null hypothesis is not rejected. These types of errors are inversely related, meaning that a decrease in one type of error causes an increase in the other.

The inequality is \(115\leq x\leq 495\)

What is inequality?

A connection is termed an inequality if two real numbers or algebraic expressions are connected by the symbols ">", "<", "≥". Inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa. Literal inequalities are relationships between two algebraic expressions that are expressed using the inequality symbols.

The number of electrons in a neutral atom is equal to the number of protons.

Before the fifth house, there is a 75% probability of finding a house with a dog. This is due to the fact that a dog is likely to be present in a home 60% of the time, or in 3 out of every 5 homes.

The likelihood that a dog will be in a house before the sixth house is determined by that likelihood. If there is a 60% chance that a home has a dog, then 3 out of every 5 homes have a dog. There is a 3/5 chance that we will find a home with a dog if we consider 4 houses before the fifth. P(A) = 1 - (1-P(A))n, where P(A) is the probability of finding a house with a dog before the fifth house and n is the number of houses, can be used to determine the likelihood of discovering one before the fifth house (4 in this case). Hence, P(A) is equal to 1 - (1 - 0.6)4 = 0.75, or 75%. This indicates that before the sixth house, there is a 75% chance that you will locate a home with a dog.

Answer:

option D is pretty close but not parallel obviously

Answer: The probability of the first player being the center fielder is 1 out of 9 because there is only one center fielder on the team.

After the center fielder is chosen, there are 8 players remaining, and the probability of the second player being the shortstop is 1 out of 8 because there is only one shortstop on the team.

To calculate the probability of both events occurring in order, we multiply the individual probabilities:

Probability = (1/9) * (1/8) = 1/72

Therefore, the probability that the first two players in the lineup will be the center fielder and the shortstop, in that order, is 1 out of 72.

Answer:

At the beginning of the 11th day, the mass of the radioactive sample was 201.87 grams.

Step-by-step explanation:

Let's call the mass of the substance after n days "m". We can calculate the mass for each day using the formula:

m = 1300 * (1 - 0.14)^n

Plugging in n = 11:

m = 1300 * (1 - 0.14)^11

m = 1300 * 0.15572634

m = 201.87 grams

So at the beginning of the 11th day, the mass of the radioactive sample was 201.87 grams.

(3,0)

Step-by-step explanation:

For any function you can find the x-intercepts by letting y = 0 (and also the y-intercept by letting x = 0 but we don't need this right now)

Here, given:

x - y = 3

and let y = 0

x - 0 = 3

x = 3 So the x-intercept is at 3. Written as a point, it is the point (3,0)

Information is needed to evaluate the project's financial viability, considering factors such as the initial investment, expected cash flows, cost of capital, and project duration.

To calculate the year 1 operating cash flows (OCF), we need to subtract the year 1 costs from the year 1 revenues:

OCF = Year 1 Revenues - Year 1 Costs

OCF = $192,000 - $125,000

OCF = $67,000

To find the depreciation expense in year 3, we need to determine the depreciation method. The provided information is incomplete regarding the depreciation method, so we cannot calculate the depreciation expense in year 3 without knowing the specific method.

The change in Net Working Capital (NWC) in year 2 can be determined by multiplying the Net Working Capital percentage (given as a percentage of t+1 revenues) by the year 1 revenues and subtracting the result from the year 2 revenues:

Change in NWC = (Year 2 Revenues - Net Working Capital percentage * Year 1 Revenues) - Year 1 Revenues

Without the specific Net Working Capital percentage or Year 2 Revenues values, we cannot calculate the exact change in NWC in year 2.

The net cash flow from salvage (ATSV) is calculated by multiplying the Salvage Value percentage by the Initial Cost:

ATSV = Salvage Value percentage * Initial Cost

ATSV = 28% * $390,000

ATSV = $109,200

To calculate the project's NPV, we need the cash flows for each year, the cost of capital, and the project duration. Unfortunately, the information provided does not include the cash flows for each year, so we cannot calculate the project's NPV.

Answer:

Step-by-step explanation:

As per the given data, r'(t) · r''(t) = \(108e^{(2t)} - 72e^{(-2t)} + 72te^{(2t)\).

To discover t(zero), we want to alternative 0 for t inside the given feature r(t). This offers us:

\(r(0) = 3e^{(2(0)}), 3e^{(-2(0)}), 3(0)e^{(2(0)})\\\\= 3e^0, 3e^0, 0\\\\= 3(1), 3(1), 0\\\\= 3, 3, 0\)

Therefore, t(0) = (3, 3, 0).

To find r''(0), we need to locate the second one derivative of the given feature r(t). Taking the by-product two times, we get:

\(r''(t) = (3e^{(2t)})'', (3e^{(-2t)})'', (3te^{(2t)})''= 12e^{(2t)}, 12e^{(-2t)}, 12te^{(2t)} + 12e^{(2t)}\)

Substituting 0 for t in r''(t), we have:

\(r''(0) = 12e^{(2(0)}), 12e^{(-2(0)}), 12(0)e^{(2(0)}) + 12e^{(2(0)})\\\\= 12e^0, 12e^0, 12(0)e^0 + 12e^0\\\\= 12(1), 12(1), 0 + 12(1)\\\\= 12, 12, 12\)

Therefore, r''(0) = (12, 12, 12).

Finally, to discover r'(t) · r''(t), we need to calculate the dot made of the first derivative of r(t) and the second spinoff r''(t). The first spinoff of r(t) is given by using:

\(r'(t) = (3e^{(2t)})', (3e^{(-2t)})', (3te^{(2t)})'\\\\= 6e^{(2t)}, -6e^{(-2t)}, 3e^{(2t)} + 6te^{(2t)\)

\(r'(t) · r''(t) = (6e^{(2t)}, -6e^{(-2t)}, 3e^{(2t)} + 6te^{(2t)}) · (12, 12, 12)\\\\= 6e^{(2t)} * 12 + (-6e^{(-2t)}) * 12 + (3e^{(2t)} + 6te^{(2t)}) * 12\\\\= 72e^{(2t)} - 72e^{(-2t)} + 36e^{(2t)} + 72te^{(2t)\)

Thus, r'(t) · r''(t) = \(108e^{(2t)} - 72e^{(-2t)} + 72te^{(2t)\).

Answer:

I'll solve 27. To give you a hint.

m2 = 1 + 3x

180 = 1 + 3x

-1       -1

179 = 3x

/3       /3

x = 59.6666667 rounded up

x = 59.67

sorry for the delay.

Step-by-step explanation:

25)

29 + 29 = a

180 - a = x

x = ?

26)

180 - 80 = a

(divide a by two)

a /2 = x

x = ?

27) (I noticed someone did this question, but it's not the right answer)

{m∠2 is the measure of angle two, not 2 degrees just in case you get confused.}

180 - 130 = a

a /2 = m∠ 2

(once you have found out the measure of angle two, use it to plug in the given equation to find the value of x.)

m∠ 2 = 1 + 3x

28)

180 - 90 = a

a /2 = m∠ 2

m∠ 2 = 2x + 21

x = ?

29) {Triangle E will be the left triangle with an angle of 68 degrees. Triangle F will be the right triangle with an angle of x degrees.}

68 + 68 = a

180 - a = b

{since b is part of the right angle, 90 degrees, in Triangle E. remember that the red-colored box-shaped angle is right angle aka measure angle is 90 degrees.}

90 - b = c

{since c is another part of the right angle in Triangle F}

180 - c = d

d /2 = value of x

x = ?

30) again, the same way to solve this like in the previous question.

{Triangle G will be the left triangle with an angle of 68 degrees. Triangle H will be the right triangle with an angle of x degrees.}

77 + 77 = a

180 - a = b

{since b is part of the right angle, 90 degrees, in Triangle G.}

90 - b = c

{since c is another part of the right angle in Triangle H}

180 - c = d

d /2 = value of x degrees

x = ?

31) same way, again. do you remember that we were solving for x in the last two questions? We're doing the same thing again, but this time, we're solving for m∠ 2 {measure of angle two in Triangle K} in order to use the given equation {m∠ 2 = 5x + 14} to find the value of x}

{Triangle J will be the left triangle with an angle of 61 degrees. Triangle K will be the right triangle with m∠2, the measure of angle two }

61 + 61 = a

180 - a = b

{since b is part of an angle 90 degrees in Triangle J, let's find the other part of the right angle in Triangle K}

90 - b = c

180 - c = d

d /2 = m∠ 2

(now use that m∠ 2 and plug it in the equation to find the value of x)

m<2 = 5x + 14

x = ?

32) Triangle L will be the left triangle with an angle of x degrees. Triangle M will be the right triangle with an angle of 38 degrees.

{since 38 degrees is already part of the right angle, 90 degrees in Triangle M. We can use it to find the other part of the right angle in Triangle L.}

90 - 38 = a

(notice that a is equal to m∠ 2 in Triangle L)

a = m∠ 2

m∠ 2 = 9x - 2

x = ?

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

33) "In any triangle, the smallest angle is always across from the shortest side and the largest angle is always across from the longest side."

basically, the longest side of a triangle is opposite to/faces the largest angle. the smallest side of a triangle is opposite to/faces the smallest angle. Always.  

Side JL, 21, is the largest side length and is opposite to angle K, which is the largest angle.

Side JK, 15, is the smallest side length and is opposite to angle L, which is the smallest angle.

The angle J is in between angle K and angle L
