Answers
Answer:
The actual diameter of Venus is 12,100 kilometers.
Step-by-step explanation:
Since William is building a planetary path for people to walk through, and the planetary path will have a model of the sun and model of the planet, and William uses two different scales, he uses 1 cm to 1000 km for the diameter of each planet and 1m to 1000000km for the distance of the sun to each planet, if William makes a model of planet Venus and the model has a diameter of 12.1, to work out the real diameter of Venus the following calculation must be performed:
1 cm = 1000 km
12.1 cm = X km
1 = 1000
12.1 = X
12.1 x 1000/1 = X
12,100 = X
Thus, the actual diameter of Venus is 12,100 kilometers.

3x+5⁰ 2x-25⁰ supplementary angles
Answers
Answer:
x=40, ∠ACB=125, ∠ACD= 55
Step-by-step explanation:
In order to solve this, you have to find the x-value. We know that these angles are supplementary, which means that the angles, ∠ACB and ∠ACD, both add up to 180°.
With this information, we can conclude 3x+5+2x-25=180.
To solve this equation for x,
1. Combine like terms
5x-20=180
2. Add 20 to both sides
5x=200
3. Divide both sides by 5.
x=40
Now we have the x-value. All we have left to do is plug that in to both of the equations for the angles.
1. ∠ACB: 3(40)+5
120+5
∠ACB = 125
2. ∠ACD: 2(40)-25
80-25
∠ACD = 55
Answer:x=40
Step-by-step explanation:
5x-20=180
5x=200

(Beautiful Mind) There is an interesting scene in A Beautiful Mind in which John Nash's character discovers his equilibrium concept. The setup is that there are four men and five women at a bar, and each man must simultaneously walk over to a woman. One of the women, who is blonde, is considered to be more desirable than the other four, who are all brunettes. Although the men all prefer the blonde to the brunettes, if they all go for the blonde they will "block each other" (according to the logic of the movie) and end up unsuccessful; moreover, after going for the blonde, they cannot then go to a brunette because the brunette would be offended at being someone's second choice and would turn down the man. Nash's character then realizes that what ought to happen is for each of the four men to choose a brunette. Let's try to put this situation in a game theoretic model by using a to denote the payoff a man would receive if another man goes for the same woman he does (here there are assumptions that it is possible to "block each other" on brunettes and that being "blocked" on a brunette gives the same payoff as being "blocked" on a blonde, although this is not important for the problem). We'll use b to refer to a man's payoff if he is the only man to go for a woman and that woman is a brunette. We'll use c to refer to a man's payoff if he is the only man to go for a woman and that woman is blonde. The natural restrictions on payoffs are a < b < c. Is there a pure strategy Nash equilibrium where each man ends up with a brunette? What are the pure strategy Nash equilbria? How do these answers change if the blonde turns down everyone (meaning that the payoff to going to the blonde is a, regardless of how many men choose her)? [Hint: classify situations based on how many men go to the blond woman.]
Answers
In the absence of the blonde turning down everyone, the pure strategy Nash equilibrium is for all men to choose brunettes. If the blonde turns down everyone, the pure strategy Nash equilibrium remains the same: all men choosing brunettes.
How to explain the Nash equillbriumIn this case, all four men choose brunettes. Since no man is going for the blonde, their payoff is b if they are the only man going for a brunette. This scenario is a pure strategy Nash equilibrium because no man has an incentive to deviate.
If one man goes for the blonde, his payoff is c. The other three men choose brunettes, resulting in a payoff of b. This situation is not a Nash equilibrium because the man going for the blonde has an incentive to deviate and choose a brunette instead, increasing his payoff to b.
Since the payoffs are the same for any number of men going for the blonde, the pure strategy Nash equilibrium is for all men to choose brunettes. Each man's payoff will be b, regardless of whether they choose the blonde or a brunette.

Recall the following definition of an Geometric Sequence. A sequence do, 21, 22, ... is called an geometric sequence if, and only if there is a constant r such that ak = r.24-1 where k> 1. Also recall that we "claimed" the explicit formula for the nth term of the geometric sequence is given by an = no pot where n > 0. Use mathematical induction to prove that our claim is true.
Answers
To prove that the explicit formula for the nth term of a geometric sequence is given by an = a₀.rⁿ, we will use mathematical induction. Mathematical induction is a proof technique used to establish a statement or property for all natural numbers or integers greater than or equal to a starting value.
Step 1: Base Case
For n = 0, the formula gives a₀.r⁰ = a₀, which is the first term of the sequence. So, the formula holds true for the initial value.
Step 2: Inductive Hypothesis
Assume that the formula holds for some arbitrary value k, i.e., ak = a₀.rᵏ.
Step 3: Inductive Step
We need to prove that the formula also holds for k+1, i.e., a(k+1) = a₀.r^(k+1).
Using the definition of a geometric sequence, we have:
a(k+1) = r.aₖ
Now substitute the inductive hypothesis into the above equation:
a(k+1) = r.(a₀.rᵏ) = (r.a₀).rᵏ = a₀.r^(k+1)
Therefore, we have shown that if the formula holds for k, then it also holds for k+1.
Step 4: Conclusion
By the principle of mathematical induction, the explicit formula for the nth term of a geometric sequence, given by an = a₀.rⁿ, is true for all non-negative integers n.
Thus, we have proved the claim using mathematical induction.
The question should be:
Recall the following definition of an Geometric Sequence.
A sequence a₀, a₁, a₂, ... is called an geometric sequence if, and only if there is a constant r such that
ak = r.a_k_-1 where k≥ 1.

If f(x) is irreducible over R. then f(x²) is irreducible over R. True / False
Answers
The statement "If f(x) is irreducible over R, then f(x²) is irreducible over R" is false. The irreducibility of f(x) does not guarantee the irreducibility of f(x²) over R.
Does the irreducibility of f(x) over R imply the irreducibility of f(x²) over R? True / FalseThe statement "If f(x) is irreducible over R, then f(x²) is irreducible over R" is actually false. In other words, just because a polynomial, f(x), is irreducible over the real numbers (R), it does not necessarily mean that its square, f(x²), will also be irreducible over R.
To understand why, let's first clarify the concept of irreducibility.
A polynomial is considered irreducible if it cannot be factored into a product of two or more non-constant polynomials with coefficients in the same field. In this case, we are considering the field of real numbers (R).
Now, when we square a polynomial, such as f(x)² or f(x²), it can lead to changes in its factorization.
The squared polynomial may introduce new factors or change the multiplicity of existing factors.
This means that the irreducibility of the original polynomial, f(x), does not necessarily carry over to the squared polynomial, f(x²).
To illustrate this, let's consider an example. Suppose we have a polynomial f(x) = x² + 1, which is irreducible over R. If we square this polynomial, we get f(x²) = (x² + 1)² = x⁴ + 2x² + 1.
The squared polynomial, in this case, is no longer irreducible over R because it can be factored as (x² + 1)(x² + 1).
This example shows that the irreducibility of f(x) does not imply the irreducibility of f(x²). It's important to carefully analyze the specific factors and properties of each polynomial to determine its irreducibility.

b. conditionally convergent

Answers
The given series Σ (bnₙⁿ cos nπ)/n is conditionally convergent.
To determine the convergence of the series, we need to examine the behavior of the terms and apply the convergence tests. Given that {bₙ} is a sequence of positive numbers that converges to 1/2, we can conclude that bnₙⁿ approaches 1/2 as n approaches infinity.
Considering the term (bnₙⁿ cos nπ)/n, we have the alternating factor cos nπ which oscillates between -1 and 1 as n varies. The absolute values of the terms bnₙⁿ/n decrease monotonically to zero.
By the Alternating Series Test, if a series has alternating signs and the absolute values of its terms decrease monotonically to zero, then the series is conditionally convergent. Therefore, the given series Σ (bnₙⁿ cos nπ)/n is conditionally convergent.

Step-by-step explanation:
First, you need to find the equation.
f(x) = -3x + b
Now we need to find the y-intercept.
f(x) = -3x + b
f(-9) = -3(1) + b
-9 = -3 + b
-6 = b
f(x) = -3x - 6
The zero of f means that f(x) = 0
f(0) = -3x - 6
f(6) = -3x

The expression for a(t) is 8(1-t)/(1+t)² and A(2) = -8/9.
What is the expression of a(t)?An expression is a combination of numbers, variables, and operations. Expressions can be used to represent quantities, relationships, and functions. While there are different types of expression such as arithmetic expression, algebraic expression and function, this as an algebraic expression.
To determine the expression that represents a(t); we have to factor the expression 8t/(1+t²).
8t/(1+t²) = 8t/(1+t)(1-t)
Dividing by 1 - t
a(t) = 8t/(1+t)
Simplifying further;
a(t) = 8(1-t)/(1+t)²
To solve for A(2), we need to plug t = 2 into the expression;
A(2) = 8(1-2)/(1+2)²
