did we prove the conclusion true for every isosceles triangle or only for this specific isosceles triangle?
∠A = ∠C for every isosceles triangle and not only for this specific isosceles triangle.
We are given that:
AB = BC
Now, draw a angle bisector from point B to the line AC in a way that it intersects AC at D.
Now, we get that:
∠ABD = ∠CBD ( BD is the angle bisector)
BD = BD ( common line)
So, ΔABD ≅ Δ CBD ( SAS property)
So,
∠A = ∠ C ( CPCT rule)
Also, it will be true for every isosceles triangle.
Therefore, we get that, ∠A = ∠C for every isosceles triangle and not only for this specific isosceles triangle.

Wanda has $3. 55 in dimes and quarters. She has 3 more quarters than dimes. How many quarters does she have?
Wanda has 11 quarters. Let's start by using variables to represent the number of dimes and quarters that Wanda has. Let:
d = the number of dimes Wanda has
q = the number of quarters Wanda has
From the problem, we know that:
Wanda has $3.55 in total, which is the sum of the value of the dimes and the quarters. We can express this as:
0.10d + 0.25q = 3.55
Wanda has 3 more quarters than dimes. We can express this as:
q = d + 3
Now we can use the second equation to substitute q in the first equation:
0.10d + 0.25(q) = 3.55
0.10d + 0.25(d + 3) = 3.55 (substitute q = d + 3)
0.10d + 0.25d + 0.75 = 3.55
0.35d = 2.80
d = 8
So Wanda has 8 dimes. Using the second equation again, we can find how many quarters she has:
q = d + 3 = 8 + 3 = 11
Therefore, Wanda has 11 quarters.

Which one of the following modes of entry offers the highest level of control to the investing firms? a. Contractual Agreements b. Joint Venture c. Equity Participation d. FDI
DI is generally considered to provide the highest level of control to investing firms compared to other modes of entry.
The mode of entry that offers the highest level of control to the investing firms is d. FDI (Foreign Direct Investment).
Foreign Direct Investment refers to when a company establishes operations or invests in a foreign country with the intention of gaining control and ownership over the assets and operations of the foreign entity. With FDI, the investing firm has the highest level of control as they have direct ownership and decision-making authority over the foreign operations. They can control strategic decisions, management, and have the ability to transfer technology, resources, and knowledge to the foreign entity.
In contrast, the other modes of entry mentioned have varying levels of control:
a. Contractual Agreements: This involves entering into contractual agreements such as licensing, franchising, or distribution agreements. While some control can be exercised through these agreements, the level of control is typically lower compared to FDI.
b. Joint Venture: In a joint venture, two or more firms collaborate and share ownership, control, and risks in a new entity. The level of control depends on the terms of the joint venture agreement and the ownership structure. While some control is shared, it may not offer the same level of control as FDI.
c. Equity Participation: Equity participation refers to acquiring a minority or majority stake in a foreign company without gaining full control. The level of control depends on the percentage of equity acquired and the governance structure of the company. While equity participation provides some level of control, it may not offer the same degree of control as FDI.

y = x^4 – 4x^3.
I’ll be thankful if someone answers I’ve a deadline to meet
Answer: (0,0) and (3,-27)
Step-by-step explanation:
Given
Function is \(y=x^4-4x^3\)
The stationary point on the graph are the points where the function is neither increasing nor decreasing i.e.
\(\Rightarrow \dfrac{dy}{dx}=4x^3-4\times 3x^2\\\\\Rightarrow \dfrac{dy}{dx}=4x^3-12x^2=0\\\\\Rightarrow 4x^2(x-3)=0\ \text{i.e.}\\\\\Rightarrow x=0\ \text{or}\ 3\)

Suppose that x is normally distributed with a mean of 50 and a standard deviation of 9. What is P(33.53
If x is normally distributed with a mean of 50 and a standard deviation of 9, then P(33.53 ≤ x ≤ 70.97) = 0.9565
First we find the z-score for P(x ≥ 33.53 ) and P(x ≤ 70.97)
We find that using the following formula :
z = (x – μ) / σ
where μ is the mean
and σ is the standard deviation
here μ = 50 and σ = 9
For P (x ≥ 33.53 ),
z = (33.53 - 50)/9
z = -1.83
So, for this z-score P(x ≥ 33.53 ) = 0.0336
For P (x ≤ 70.97),
z = (70.97 - 50)/9
z = 2.33
So, for this z-score P (x ≤ 70.97) = 0.9901
Now we find P(33.53 ≤ x ≤ 70.97) = 0.9901 - 0.0336
= 0.9565
Therefore, the required probability is 0.9565

A bag has purple, pink and yellow marbles.
The probability of selecting a purple marble is 1/6
and the probability of selecting a pink marble is
3/4
Find the probability of selecting a yellow
marble.
Answer:
1/12
Step-by-step explanation:
P(yellow) + P(purple) + P(pink) = 1, because all probabilities have to add up to 1 (100%).
P(yellow) = 1 - P(purple) - P(pink)
= 1 - 1/6 - 3/4
= 1/12.
so, the probability of selecting a yellow marble is 1/12

The average age of 6 men is 35 years and the average age of four of them is 32 year.
Find the ages of the remaining two ment one is 3 years older than the other.
Let's denote the ages of the two remaining men as x and x + 3 (since one is 3 years older than the other).
We know that the average age of 6 men is 35 years. So, the sum of their ages is 6 * 35 = 210 years.
We also know that the average age of four of them is 32 years. So, the sum of their ages is 4 * 32 = 128 years.
To find the sum of the ages of the two remaining men, we subtract the sum of the ages of the four men from the sum of the ages of all six men:
210 - 128 = 82 years.
Now, we can set up an equation to solve for the ages of the remaining two men:
x + (x + 3) = 82.
Combining like terms, we get:
2x + 3 = 82.
Subtracting 3 from both sides:
2x = 79.
Dividing both sides by 2:
x = 39.5.
So, one of the remaining men is 39.5 years old, and the other is 39.5 + 3 = 42.5 years old.

F. 192 centimeters anf 0.19 meters
(suggested by my sister plz help her ty)
Answer:
The answer is letter A and letter F.
Step-by-step explanation:
The question is asking if any of these choices are less than 300 centimeters. To find this out, first, you have to convert the meters to centimeters, to make it easier. (1 centimeter is equal to 0.01 meters) Multiply the meters by 100. For example 1.8m x 100 = 180cm. Do the rest for the other meters and then add them to the centimeters. Example: 180cm + 110cm = 290cm, which is less than 300cm.

Using an integrating factor, solve y-y-5 CD- in the method for solving a first-order linear differential equation, the first step is to put the equation in the standard form y alty bit). is the given equation in the standard form? No Yes Identify a(t) and bit)
The value of a(t) is -1 and b(t) is 55 + \(e^t\)
No, the given equation y' - y = 55 + \(e^t\) is not in the standard form of a first-order linear differential equation.
In the method for solving a first-order linear differential equation, an integrating factor is a function used to transform the equation into a form that can be easily solved.
For an equation in the standard form y' + a(t)y = b(t), the integrating factor is defined as:
μ(t) = e^∫a(t)dt
To solve the equation, you multiply both sides of the equation by the integrating factor μ(t) and then simplify. This multiplication helps to make the left side of the equation integrable and simplifies the process of finding the solution.
To put it in standard form, we need to rewrite it as y' + a(t)y = b(t).
Comparing the given equation with the standard form, we can identify:
a(t) = -1
b(t) = 55 + \(e^t\)
Therefore, The value of a(t) is -1 and b(t) is 55 + \(e^t\)

What is directrix of parabola?The directrix of a parabola is a line that is perpendicular to the axis of the parabola. The directrix of the parabola helps in defining the parabola. A parabola represents the locus of a point which is equidistant from a fixed point called the focus and the fixed line called the directrix. The directrix and the focus are equidistant from the vertex of the parabola. Here we define the directrix for the standard equations of a parabola.
The directrix of the parabola y^2 = 4ax, having x-axis as its axis, passes through (-a, 0), and has the equation x + a = 0.The directrix of the parabola y^2 = -4ax, having x-axis, passes through (a, 0), and has the equation x - a = 0.The directrix of the parabola x^2 = 4ay, having y-axis as its axis, passes through (0, -a), and has the equation y + a = 0.The focus of the parabola x^2 = -4ay, having y-axis as its axis, passes through (0, a), and has the equation y - a = 0.Given:
