The value of x from the given circle is 4
What is intersecting chord theorem?The intersecting chords theorem is a statement in geometry that describes a relation of the four line segments created by two intersecting chords within a circle.
It states that the products of the lengths of the line segments on each chord are equal.
According to the theorem;
x * 3 = 2 * (4 + 2)
3x = 2(6)
3x = 12
Divide both sides by 3
3x/3 = 12/3
x =4

Consider rolling a six-sided die. Let A be the set of outcomes where the roll is an even number. Let B be the set of outcomes where the roll is greater than 3. Calculate and compare the sets on both sides of De Morgan’s law.
1. [tex](A \cup B)^c = A^c \cap B^c[/tex]
2. [tex](A \cap B)^c = A^c \cup B^c[/tex]
Answer:
See below
Step-by-step explanation:
[tex]A = \{2, 4, 6\}[/tex]
[tex]A^c =\{1, 3, 5\}\\B = \{4, 5, 6\}\\B^c = \{ 1,2, 3\}[/tex]
To prove 1 we have
[tex](A \bigcup B) = \{2, 4, 6\} \bigcup \{4, 5, 6\} = \{2, 4, 5, 6\}\\(A \bigcup B) ^c =\bold{\{1,3\}}\\A^c \bigcap B^c = {\{1, 3, 5\} \bigcap \{1, 2, 3\} =\bold{\{1,3\}}\\[/tex]
Hence proved
To prove 2
[tex](A \bigcap B) = \{2, 4, 6\} \bigcap \{4, 5, 6\} = \{4, 6\}\\\\(A \bigcap B)^c = \bold{\{1,2, 3, 5\}}\\A^c \bigcup B^c = \{1, 3, 5\} \bigcup \{1, 2, 3\} = \bold{\{1,2,3,5\}}\[/tex]
Hence proved
Notes
The complement of a set is the set of all elements not in the set
Here the set of all outcomes is {1, 2, 3,4,5, 6}
So if A = {2, 4, 6} then the complement of A s=is the set of outcomes not in A ie the set {1, 3, 5} which is the set of odd numbers on a die throw

To reduce their expected estate tax liability prior to either spouse's death, the Hansens could?
If the Hansens want to reduce their expected estate tax liability prior to the death of either of the spouses, they could initiate a Marital Transfer.
What is a marital transfer?A Marital transfer simply means that the Hansens should bequest their assets to each each other in case either of them die.
If this happens, the surviving spouse will not be charged any estate taxes because bequests to spouses are not subject to taxation.
To do this, the Hansens should put it into both of their wills that they plan to gift/ bequest their assets to their spouse if they die.
The big disadvantage of using a marital transfer however, is that the estate will still be subject to taxes when the surviving spouse dies. All the estate taxes that had been avoided would then be incurred by the estate but only after the death of both spouses.
In conclusion, they should use a marital transfer.

Solve -7(m-1)= -(3m-1)
Please give work
Answer:
m = 3/2
Step-by-step explanation:
-7(m-1)= -(3m-1)
-7m + 7 = -3m + 1
-4m = -6
m = 3/2
Check.
-7(m-1)= -(3m-1)
-7(3/2 - 1) = -(3*3/2 - 1)
-7(1/2) = -(4.5 - 1)
-3.5 = -3.5
Use the distributive property to multiply −7 by m−1.
−7m+7=−(3m−1)To find the opposite of 3m−1, find the opposite of each term.
−7m + 7 = −3m −( − 1 )The opposite of −1 is 1.
−7m + 7= −3m + 1Add 3m to both sides.
−7m + 7 + 3m = 1Combine −7m and 3m to get −4m.
−4m + 7 = 1Subtract 7 from both sides.
−4m = 1 − 7Subtract 7 from 1 to get −6.
−4m = −6Divide both sides by −4.
m = -6/-4Reduce the fraction -6/-4 to its lowest expression by extracting and canceling −2.

Answer: B: (1-5x²)³, all real numbers
Step-by-step explanation:
The notation [tex]f\circ g(x)[/tex] is called function composition, which is where you pass one function in as the value of another function. In other words, [tex]\( f\circ g(x)=f(g(x)) \)[/tex].

The baseball team has a double-header on Saturday. The probability that they will win both games is 34%. The probability that they will win the first game is 75%, What is the probability that the team will win the second game given that they have already won the first game?
Considering the definition of conditional probability, the probability that the team will win the second game given that they have already won the first game is 45.33%.
Definition of probabilityProbability is the greater or lesser chance that a given event will occur.
In other words, the probability establishes a relationship between the number of favorable events and the total number of possible events.
Conditional probabilityConditional probability is the probability that a given event will occur given that another event occurs. The conditional probability operator is the │ sign.
In other words, the conditional probability is the probability of some event A , given the occurrence of some other event B and is denoted by P(A|B) and is read “the probability of A , given B ”.
Then, when an event influences the outcome of a second event, the probability of the second event is said to be a conditional probability and is calculated using the expression:
P(A|B)= P(A∩B) ÷ P(B)
where:
the probability of event B cannot be zero.P(A∩B) is the probability of both events happening.Probability that the team win the second gameIn this case, you know that:
B: The baseball team win the first game.A: The baseball team win the second game.The probability that they will win both games is 34% → P(A∩B)= 0.34The probability that they will win the first game is 75% → P(B)= 0.75Replacing in the definition of conditional probability:
P(A|B)= 0.34 ÷ 0.75
P(A|B)= 0.4533= 45.33%
Finally, the probability that the team will win the second game given that they have already won the first game is 45.33%.

Teresa earns a weekly salary of $825 and a 6% commission on her total sales.
Ramón earns a weekly salary of $1,350 and a 2% commission on sales. What
amount of sales, x, will result in each of them earning the same amount for the
week?
To estimate the amount of sales, x, will result in each of them earning the same amount for the week and we can set up the following equation:
T = R
825 + 0.06x = 1350 + 0.02x
Simplifying the equation, we get
x = 13125
We require a total of 13125 for the number of sales to maintain the same amount for Ramon and Teresa at the end of the week.
How to estimate the number of sales, x, that will result in each of them gaining the exact amount for the week?
For this case, we can assume that the total salary for Teresa T is given by T = 825 + 0.06x
Where x represents the number of sales. And similarly the total salary of Ramon we have:
R = 1350 + 0.02x
We want to estimate the amount of sales, x, will result in each of them earning the same amount for the week and we can set up the following equation:
T= R
825 + 0.06x = 1350 + 0.02x
Multiply both sides by 100
[tex]$825 \cdot 100+0.06 x \cdot 100=1350 \cdot 100+0.02 x \cdot 100$[/tex]
82500 + 6x = 135000 + 2 x
Subtract 82500 from both sides
82500 + 6x - 82500 = 135000 + 2x - 82500
6x = 2x + 52500
Subtract 2x from both sides
6x - 2x = 2x + 52500 - 2x
4x = 52500
Divide both sides by 4
[tex]$\frac{4 x}{4}=\frac{52500}{4}$[/tex]
x = 13125
So then we require a total of 13125 for the number of sales to maintain the same amount for Ramon and Teresa at the end of the week.

How to find an algebraic expression by long division
Long division is an algebraic procedure with which we can find the result of a division of two polynomials. Now we proceed to present the entire procedure explained:
(a) a² - b² + 2 · b · c - c² divided by a + b - c.
1) Multiply a + b - c by a and subtract it from a² - b² + 2 · b · c - c²: Result: a / Remainder: - b² - a · b + 2 · b · c + a · c - c²
2) Multiply a + b - c by - b and subtract it from the result of 1): Result: a - b / Remainder: b · c + a · c - c²
3) Multiply a + b - c by c and subtract it from the result of 2): Result: a - b + c / Remainder: 0
The result of the long division is a - b + c.
(b) 3 · m⁷ - 11 · m⁵ + m⁴ + 18 · m³ - 8 · m + 3 · m² + 4 divided by m⁴ - 3 · m² + 4.
1) Multiply m⁴ - 3 · m² + 4 by 3 · m³ and subtract it from 3 · m⁷ - 11 · m⁵ + m⁴ + 18 · m³ - 8 · m + 3 · m² + 4: Result: 3 · m³ / Remainder: 2 · m⁵ + m⁴ + 6 · m³ - 8 · m + 3 · m² + 4.
2) Multiply m⁴ - 3 · m² + 4 by 2 · m and subtract it from the result of 1): Result: 3 · m³ + 2 · m / Remainder: m⁴ + 12 · m³ - 16 · m + 3 · m² + 4.
3) Multiply m⁴ - 3 · m² + 4 by 2 · m and subtract it from the result of 2): Result: 3 · m² + 2 · m + 1 / Remainder: 12 · m³ - 16 · m + 6 · m².
The result of the long division is 3 · m² + 2 · m + 1 + (12 · m³ - 16 · m + 6 · m²) / (m⁴ - 3 · m² + 4).

Find the value of x in the triangle shown below.
x =
98°
27°
Answer: 55
Step-by-step explanation: There is one simple theorem we need to know in order to solve for this.
Triangle Angle-Sum Property: All three angles interior angles of a triangle add up to 180°.
Thus, we could label the points A, B, and C, and set up an algebraic expression.
Let A = 27, B = 98, and C = x.
A + B + C = 180°.
Substituting A, B, and C we get:
27 + 98 + x = 180°.
Adding, we get:
125 + x = 180°
Subtracting 125 by 180, we get:
x = 55°
Thus, the angle X is 55°.
We could have simply solved this by just doing 180 - 98 - 27 = 55 in the first place, but I wanted to show you how I got such results.

A candle on pauline’s dresser is 10 inches tall and burns at a rate of 0.75 inches per hour. how many hours will it take for the candle to burn down to a height of .25 inches?
Using a linear function, it is found that it will take 13 hours for the candle to burn down to a height of .25 inches.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Considering the situation described, the y-intercept is of 10 while the slope is of -0.75, hence the height of the candle after t hours is given by:
h(t) = 10 - 0.75t
The height will be of 0.25 inches when h(t) = 0.25, hence:
0.25 = 10 - 0.75t
0.75t = 9.75
t = 9.75/0.75
t = 13 hours.
