The value of k is -36, if (x−2) is a factor of 4x3+3x2−4x+k.
To find the value of k, we can use the factor theorem. According to the factor theorem, if (x - 2) is a factor of the polynomial [tex]4x^3 + 3x^2 - 4x + k[/tex], then substituting x = 2 into the polynomial should result in a zero.
Let's substitute x = 2 into the polynomial:
[tex]4(2)^3 + 3(2)^2 - 4(2)[/tex] + k = 0
Simplifying the equation:
32 + 12 - 8 + k = 0
36 + k = 0
k = -36

I want you to make sure that you have learned the basic math used in establishing the existence of Nash equilibria in mixed strategies. Hope that the following questions help! 1. First, please answer the following questions which by and large ask definitions. (a) Write the definition of a correspondence. (b) Write the definition of a fixed point of a correspondence. 1 (c) In normal form games, define the set of (mixed strategy) best replies for a given player i. Then define the "best reply correspondence," denoted by B in class. (d) Formally prove that a mixed strategy profile α∗ is a Nash equilibrium if and only if it is a fixed point of the (mixed strategy) best reply correspondence. 2. Now I ask about Brower's fixed point theorem, a well-known fixed point theorem which we didn't formally cover in class (but can be learned through this problem set!). (a) Formally state Brower's fixed point theorem. Find references by yourself if you don't know the theorem. You can basically copy what you found, but make sure that you define all symbols and concepts so that the statement becomes self-contained and can be understood by readers who do not have access to the reference you used. (b) Prove that Brower's fixed point theorem is a corollary of Kakutani's fixed point theorem. In other words, prove the former theorem using the latter. 3. When we discussed Kakutani's fixed point theorem in class, I stated several conditions and explained that the conclusion of Kakutani's theorem does not hold if one of the conditions are not satisfied, but only gave examples for some of those conditions. Now, in the following questions let us check that other conditions cannot be dispensed with (I use the same notation as in class in the following questions). (a) Provide an example without a fixed point in which the set S is not closed, but all other conditions in Kakutani's theorem are satisfied. Explain why this is a valid counterexample. 21 Recall that the concept of a fixed point is well-defined only under the presumption that a correspondence is defined as a mapping from a set to itself. 2 To be precise, when we require that "the graph of F be closed" in your example, interpret the closedness as being defined with respect to the relative topology in S².
1. Definition of a correspondence: A correspondence is a mathematical concept that defines a relation between two sets, where each element in the first set is associated with one or more elements in the second set. It can be thought of as a rule that assigns elements from one set to elements in another set based on certain criteria or conditions.
2. Definition of a fixed point of a correspondence: In the context of a correspondence, a fixed point is an element in the first set that is associated with itself in the second set. In other words, it is an element that remains unchanged when the correspondence is applied to it.
3. Set of (mixed strategy) best replies in normal form games: In a normal form game, the set of (mixed strategy) best replies for a given player i is the collection of strategies that maximize the player's expected payoff given the strategies chosen by the other players. It represents the optimal response for player i in a game where all players are using mixed strategies.
Best reply correspondence: The "best reply correspondence," denoted by B in class, is a correspondence that assigns to each mixed strategy profile the set of best replies for each player. It maps a mixed strategy profile to the set of best responses for each player.
4. Nash equilibrium and fixed point of best reply correspondence: A mixed strategy profile α∗ is a Nash equilibrium if and only if it is a fixed point of the best reply correspondence. This means that when each player chooses their best response strategy given the strategies chosen by the other players, no player has an incentive to unilaterally change their strategy. The mixed strategy profile remains stable and no player can improve their payoff by deviating from it.
5. Brower's fixed point theorem: Brower's fixed point theorem states that any continuous function from a closed and bounded convex subset of a Euclidean space to itself has at least one fixed point. In other words, if a function satisfies these conditions, there will always be at least one point in the set that remains unchanged when the function is applied to it.
6. Proving Brower's theorem using Kakutani's fixed point theorem: Kakutani's fixed point theorem is a more general version of Brower's fixed point theorem. By using Kakutani's theorem, we can prove Brower's theorem as a corollary.
Kakutani's theorem states that any correspondence from a non-empty, compact, and convex subset of a Euclidean space to itself has at least one fixed point. Since a continuous function can be seen as a special case of a correspondence, Kakutani's theorem can be applied to prove Brower's theorem.
7. Conditions for Kakutani's fixed point theorem: Kakutani's fixed point theorem requires several conditions to hold in order to guarantee the existence of a fixed point. These conditions include non-emptiness, compactness, convexity, and upper semi-continuity of the correspondence.
If any of these conditions are not satisfied, the conclusion of Kakutani's theorem does not hold, and there may not be a fixed point.
8. Example without a fixed point: An example without a fixed point can be a correspondence that does not satisfy the condition of closedness in the relative topology of S², where S is the set where the correspondence is defined. This means that there is a correspondence that maps elements in S to other elements in S, but there is no element in S that remains unchanged when the correspondence is applied.
This is a valid counterexample because it shows that even if all other conditions of Kakutani's theorem are satisfied, the lack of closedness in the relative topology can prevent the existence of a fixed point.

GH bisects angle FGI. If angle FGH is 43 degrees, what is angle IGH?
If angle FGH measures 43 degrees, then angle IGH will also measure 43 degrees. The bisecting line GH divides angle FGI into two congruent angles, both of which are 43 degrees each.
Given that GH bisects angle FGI, we know that angle FGH and angle IGH are adjacent angles formed by the bisecting line GH. Since the line GH bisects angle FGI, we can conclude that angle FGH is equal to angle IGH.
Therefore, if angle FGH is given as 43 degrees, angle IGH will also be 43 degrees. This is because they are corresponding angles created by the bisecting line GH.
In general, when a line bisects an angle, it divides it into two equal angles. So, if the original angle is x degrees, the two resulting angles formed by the bisecting line will each be x/2 degrees.
In this specific case, angle FGH is given as 43 degrees, which means that angle IGH, being its equal counterpart, will also measure 43 degrees.

Future value of $500 per year for 6 years at 8%: $
Future value of $250 per year for 3 years at 4%: $
Future value of $1,000 per year for 2 years at 0%: $
Alright, let's take this step by step.
First, let's understand what an ordinary annuity is. An ordinary annuity is a series of equal payments made at the end of consecutive periods over a fixed length of time. For example, if you save $100 every year for 5 years, that’s an ordinary annuity.
Now, let’s understand the formula to calculate the future value (FV) of an ordinary annuity:
FV = P x ((1 + r)^n - 1) / r
Where:
- FV is the future value of the annuity.
- P is the payment per period (how much you save each time).
- r is the interest rate per period (in decimal form).
- n is the number of periods (how many times you save).
Let’s solve each part:
a) $500 per year for 6 years at 8%.
P = 500, r = 8% = 0.08, n = 6
FV = 500 x ((1 + 0.08)^6 - 1) / 0.08
≈ 500 x (1.59385 - 1) / 0.08
≈ 500 x (0.59385) / 0.08
≈ 500 x 7.4231
≈ 3701.55
So, the future value of $500 per year for 6 years at 8% is about $3,701.55.
b) $250 per year for 3 years at 4%.
P = 250, r = 4% = 0.04, n = 3
FV = 250 x ((1 + 0.04)^3 - 1) / 0.04
≈ 250 x (1.12486 - 1) / 0.04
≈ 250 x (0.12486) / 0.04
≈ 250 x 3.1215
≈ 780.38
So, the future value of $250 per year for 3 years at 4% is about $780.38.
c) $1,000 per year for 2 years at 0%.
P = 1000, r = 0% = 0.00, n = 2
FV = 1000 x ((1 + 0.00)^2 - 1) / 0.00
= 1000 x (1 - 1) / 0.00
= 1000 x 0
= 0
Wait, something went wrong, because we know that if we save $1000 for 2 years with no interest, we should have $2000. This is a special case, where we just sum the contributions because there's no interest:
FV = 1000 x 2
= 2000
So, the future value of $1,000 per year for 2 years at 0% is $2,000.
Now, for annuities due:An annuity due is similar to an ordinary annuity, but the payments are made at the beginning of each period instead of the end. To convert the future value of an ordinary annuity to an annuity due, you can use the following formula:
FV of Annuity Due = FV of Ordinary Annuity x (1 + r)
a) Reworked
FV of Annuity Due = 3701.55 x (1 + 0.08)
≈ 3701
.55 x 1.08
≈ 3997.67
b) Reworked
FV of Annuity Due = 780.38 x (1 + 0.04)
≈ 780.38 x 1.04
≈ 810.80
c) Reworked
FV of Annuity Due = 2000 x (1 + 0.00)
= 2000 x 1
= 2000 (This doesn't change because there's no interest).
And there you have it! The future values for both ordinary annuities and annuities due!
Complete the following items. For multiple choice items, write the letter of the correct response on your paper. For all other items, show or explain your work.Let f(x)=4/{x-1} ,
b. Find f(f⁻¹(x)) and f⁻¹(f(x)) . Show your work.
For the given function f(x)=4/{x-1}, the values of f(f⁻¹(x)) and f⁻¹(f(x)) is x and 4 + x.
The function f(x) = 4/{x - 1} is a one-to-one function, which means that it has an inverse function. The inverse of f(x) is denoted by f⁻¹(x). We can think of f⁻¹(x) as the "undo" function of f(x). So, if we apply f(x) to a number, then applying f⁻¹(x) to the result will undo the effect of f(x) and return the original number.
The same is true for f(f⁻¹(x)). If we apply f(x) to the inverse of f(x), then the result will be the original number.
To find f(f⁻¹(x)), we can substitute f⁻¹(x) into the function f(x). This gives us:
f(f⁻¹(x)) = 4 / (f⁻¹(x) - 1)
Since f⁻¹(x) is the inverse of f(x), we know that f(f⁻¹(x)) = x. Therefore, we have: x = 4 / (f⁻¹(x) - 1)
We can solve this equation for f⁻¹(x) to get: f⁻¹(x) = 4 + x
Similarly, to find f⁻¹(f(x)), we can substitute f(x) into the function f⁻¹(x). This gives us: f⁻¹(f(x)) = 4 + f(x)
Since f(x) is the function f(x), we know that f⁻¹(f(x)) = x. Therefore, we have: x = 4 + f(x)
This is the same equation that we got for f(f⁻¹(x)), so the answer is the same: f⁻¹(f(x)) = 4 + x

The company is offering a 4% interest rate for 36 months (3 years). What will your monthly payments be? S
a) You can afford a loan of approximately $91,862.33.
b) The total amount of money you will pay the loan company is $288,000.
c) Approximately $196,137.67 of that money is interest.
To determine how big of a loan you can afford, you need to consider your monthly mortgage payment, the loan term, and the interest rate. In this case, you can afford a $800 per month mortgage payment.
Using the formula for calculating the loan amount based on monthly payment, loan term, and interest rate, we can determine the loan amount you can afford. In this scenario, you have a 30-year loan at 8% interest.
Using the loan payment formula, we find that the loan amount you can afford is approximately $91,862.33.
To calculate the total amount of money you will pay the loan company, you multiply the monthly payment by the total number of payments over the loan term. In this case, it's $800 multiplied by 360 (30 years * 12 months). This gives a total payment of $288,000.
To determine how much of that total payment is interest, you subtract the loan amount from the total payment. In this case, it's $288,000 - $91,862.33, which equals approximately $196,137.67.
Therefore, you can afford a loan of approximately $91,862.33, the total amount you will pay the loan company is $288,000, and approximately $196,137.67 of that total is interest.

Given equation x²z+y²+z²=cos(yz) is given implicitly as a function of x and y.
Here, we have to find out the partial derivatives of z with respect to x and y.
So, we need to differentiate the given equation partially with respect to x and y.
To find ∂z/∂x,
Differentiating the given equation partially with respect to x, we get:
2xz+0+2zz' = -y zsin(yz)
Using the Chain Rule: z' = dz/dx and dz/dy
Similarly, to find ∂z/∂y, differentiate the given equation partially with respect to y, we get: 0+2y+2zz' = -zsin(yz) ⇒ 2y+2zz' = -zsin(yz)
Again, using the Chain Rule: z' = dz/dx and dz/dy
We can write the above equations as: z'(2xz+2zz') = -yzsin(yz)⇒ ∂z/∂x = -y sin(yz)/(2xz+2zz')
Also, z'(2y+2zz') = -zsin(yz)⇒ ∂z/∂y = [1-zcos(yz)]/(2y+2zz')
Thus, ∂z/∂x = -y sin(yz)/(2xz+2zz') and ∂z/∂y = [1-zcos(yz)]/(2y+2zz')
Hence, the answer is ∂z/∂x = -y sin(yz)/(2xz+2zz') and ∂z/∂y = [1-zcos(yz)]/(2y+2zz')

suppose that you invest $29 per month for 36 years
into an account compounded monthly. At the end of the 36 years of
the investment, you have $25,593.13 how much did you earn in
interest?
A. The interest earned would be $25,593.13 minus the total amount invested, which is $29 per month for 36 years.
B. To calculate the interest earned, we need to subtract the total amount invested from the final amount accumulated.
The total amount invested can be calculated by multiplying the monthly investment of $29 by the number of months in 36 years, which is 36 years × 12 months/year = 432 months.
So the total amount invested is $29 × 432 = $12,528.
Now, to find the interest earned, we subtract the total amount invested from the final amount accumulated.
Therefore, the interest earned is $25,593.13 - $12,528 = $13,065.13.
This means that over the 36 years of investing $29 per month, the account has earned an interest of $13,065.13.

If the surface area of the right rectangular prism is 310 square centimeters, what is the measure of the height h of the prism?
A 5 \mathrm{~cm}
B 5 \frac{1}{6} \mathrm{~cm}
C 10
D 13 \frac{3}{9} \mathrm{~cm}
The height h of the prism measures 5 cm (Option A) based on the given surface area.
To find the measure of the height of the prism, we need to understand the formula for the surface area of a right rectangular prism. The surface area of a prism is given by the formula: SA = 2lw + 2lh + 2wh, where l, w, and h represent the length, width, and height of the prism, respectively.
In this case, we are given that the surface area of the prism is 310 square centimeters. We can set up the equation as follows: 310 = 2lw + 2lh + 2wh.
Since we are asked to find the height, we can isolate the term 2lh and rearrange the equation as follows: 2lh = 310 - 2lw - 2wh.
Simplifying further, we get: lh = 155 - lw - wh.
Since we don't have specific values for the length and width, we cannot solve for the height directly. However, we can analyze the answer choices given.
Option A states that the height h is 5 cm. We can substitute this value into our equation: 5l = 155 - 5w - 5w.
Simplifying, we get: 5l = 155 - 10w.
We can see that this equation does not depend on the specific values of l and w, which means that regardless of their values, the equation holds true. Therefore, the measure of the height h of the prism is indeed 5 cm option A.

Given cosθ=-4/5 and 90°<θ<180° , find the exact value of each expression. tan θ/2
Given expression is cosθ=-4/5 and 90°<θ<180°, the exact value of tan(θ/2) is +3.
Given cosθ = -4/5 and 90° < θ < 180°, we want to find the exact value of tan(θ/2). Using the half-angle identity for tangent, tan(θ/2) = ±√((1 - cosθ) / (1 + cosθ)).
Substituting the given value of cosθ = -4/5 into the half-angle identity, we have: tan(θ/2) = ±√((1 - (-4/5)) / (1 + (-4/5))).
Simplifying this expression, we get: tan(θ/2) = ±√((9/5) / (1/5)).
Further simplifying, we have: tan(θ/2) = ±√(9) = ±3.
Since θ is in the range 90° < θ < 180°, θ/2 will be in the range 45° < θ/2 < 90°. In this range, the tangent function is positive. Therefore, the exact value of tan(θ/2) is +3.

Harriet Marcus is concerned about the financing of a home. She saw a small cottage that sells for $60,000. Assuming that she puts 25% down, what will be her monthly payment and the total cost of interest over the cost of the loan for each assumption? (Use the Table 15.1(a) and Table 15.1(b)). (Round intermediate calculations to 2 decimal places. Round your final answers to the nearest cent.) e. What is the savings in interest cost between 11% and 14.5%? (Round intermediate calculations to 2 decimal places. Round your answer to the nearest dollar amount.) f. If Harriet uses 30 years instead of 25 for both 11% and 14.5%, what is the difference in interest? (Use 360 days a year. Round intermediate calculations to 2 decimal places. Round your answer to the nearest dollar amount.)
To calculate Harriet Marcus' monthly payment and total cost of interest, we need to use the loan payment formula and the interest rate tables.
a) Monthly payment: Assuming Harriet puts 25% down on a $60,000 cottage, the loan amount is $45,000. Using Table 15.1(a) with a loan term of 25 years and an interest rate of 11%, the factor from the table is 0.008614. The monthly payment can be calculated using the loan payment formula:
[tex]\[ \text{Monthly payment} = \text{Loan amount} \times \text{Loan factor} \]\[ \text{Monthly payment} = \$45,000 \times 0.008614 \]\[ \text{Monthly payment} \approx \$387.63 \][/tex]
b) Total cost of interest: The total cost of interest over the cost of the loan can be calculated by subtracting the loan amount from the total payments made over the loan term. Using the monthly payment calculated in part (a) and the loan term of 25 years, the total payments can be calculated:
[tex]\[ \text{Total payments} = \text{Monthly payment} \times \text{Number of payments} \]\[ \text{Total payments} = \$387.63 \times (25 \times 12) \]\[ \text{Total payments} \approx \$116,289.00 \][/tex]
The total cost of interest can be found by subtracting the loan amount from the total payments:
[tex]\[ \text{Total cost of interest} = \text{Total payments} - \text{Loan amount} \]\[ \text{Total cost of interest} = \$116,289.00 - \$45,000 \]\[ \text{Total cost of interest} \approx \$71,289.00 \][/tex]
e) Savings in interest cost between 11% and 14.5%: To find the savings in interest cost, we need to calculate the total cost of interest for each interest rate and subtract them. Using the loan amount of $45,000 and a loan term of 25 years:
For 11% interest:
Total payments = Monthly payment × Number of payments = \$387.63 × (25 × 12) ≈ \$116,289.00
For 14.5% interest:
Total payments = Monthly payment × Number of payments = \$387.63 × (25 × 12) ≈ \$134,527.20
Savingsin interest cost = Total cost of interest at 11% - Total cost of interest at 14.5% =\$116,289.00 - \$134,527.20 ≈ -\$18,238.20
Therefore, the savings in interest cost between 11% and 14.5% is approximately -$18,238.20.
f) Difference in interest with a 30-year loan term: To calculate the difference in interest, we need to recalculate the total cost of interest for both interest rates using a loan term of 30 years instead of 25. Using the loan amount of $45,000 and 30 years as the loan term:
For 11% interest:
Total payments = Monthly payment × Number of payments =\$387.63 × (30 × 12) ≈ \$139,645.20
For 14.5% interest:
Total payments = Monthly payment × Number of payments =\$387.63 × (30 × 12) ≈ \$162,855.60
Difference in interest = Total cost of interest at 11% - Total cost of interest at 14.5% = \$139,645.20 - \$162,855.60 ≈

The measures of the angles of a triangle are shown in the figure below. Solve for x.
The value of x from the given triangle is approximately 29.
How to find the value of x in the triangle givenWe are asked to solve for x. We are given a triangle and all 2 angles are labeled. We know that the sum of the angles in a triangle must be 180 degrees. Therefore, the given angles: 63 and (4x + 3) must add to 180. We can set up an equation.
[tex]63+(4\text{x}+3)=180[/tex]
Now we can solve for x. Begin by combing like terms on the left side of the equation. All the constants (terms without a variable) can be added.
[tex](63+3)+4\text{x}=180[/tex]
[tex]66+4\text{x}=180[/tex]
We will solve for x by isolating it. 66 is being added to 4x. The inverse operation of addition is subtraction. Subtract 66 from both sides of the equation.
[tex]66-66+4\text{x}=180-66[/tex]
[tex]4\text{x}=180-66[/tex]
[tex]4\text{x}=114[/tex]
x is being multiplied by 4. The inverse operation of multiplication is division. Divide both sides by 4.

A = 10000(1 + 0.055/12)^(12*7)
A ≈ $13,794.60
d) Compounded Continuously:
The formula is A = Pert, where:
P = principal amount ($10,000)
r = annual interest rate (5.5% or 0.055)
t = number of years (7)
A = 10000e^(0.055*7)

Let A be an upper trangular matrix with main diagonal: \( \{1,5,-7,11,13,101\} \). Then \( 5 A^{2} \) is not defined a singular matrix an invertible matrix None of the mentioned
The determinant of 5A² is nonzero, 5A² is invertible. Thus, the correct option is that 5A² is invertible.
Let A be an upper triangular matrix with the main diagonal: {1, 5, -7, 11, 13, 101}. We need to determine whether 5A² is singular or invertible.
An n × n matrix is singular if its determinant is zero, while it is invertible if the determinant is nonzero.
The product of two upper (or lower) triangular matrices is also an upper (or lower) triangular matrix. Therefore, the matrix A² is an upper triangular matrix with a main diagonal of {(1)², (5)², (-7)², (11)², (13)², (101)²}.
Hence, 5A² will have a main diagonal with entries 5(1)², 5(5)², 5(-7)², 5(11)², 5(13)², and 5(101)², which simplifies to {5, 625, 1225, 3025, 4225, 255025}.
Therefore, the determinant of 5A² is equal to the product of its main diagonal elements:
5(1)² × 5(5)² × 5(-7)² × 5(11)² × 5(13)² × 5(101)² = (5)⁶ (1)² (13)² (11)² (5)² (101)² (-7)².
Since the determinant of 5A² is nonzero, 5A² is invertible. Thus, the correct option is that 5A² is invertible.

For Question 11: Find the time when the object is traveling up as well as down. Separate answers with a comma. A cannon ball is launched into the air with an upward velocity of 327 feet per second, from a 13-foot tall cannon. The height h of the cannon ball after t seconds can be found using the equation h = 16t² + 327t + 13. Approximately how long will it take for the cannon ball to be 1321 feet high? Round answers to the nearest tenth if necessary.
How long long will it take to hit the ground?
It takes approximately 13.3 seconds for the cannon ball to reach a height of 1321 feet and The time taken to hit the ground is approximately 0.2 seconds, after rounding to the nearest tenth.
. The height h of a cannon ball can be found using the equation `h = -16t² + Vt + h0` where V is the initial upward velocity and h0 is the initial height.
It is given that:V = 327 feet per second
h0 = 13 feet
The equation is h = -16t² + 327t + 13.
At 1321 feet high:1321 = -16t² + 327t + 13
Subtracting 1321 from both sides, we have:
-16t² + 327t - 1308 = 0
Dividing by -1 gives:16t² - 327t + 1308 = 0
This is a quadratic equation with a = 16, b = -327 and c = 1308.
Applying the quadratic formula gives:
t = (-b ± √(b² - 4ac)) / (2a)t = (-(-327) ± √((-327)² - 4(16)(1308))) / (2(16))t = (327 ± √(107169 - 83904)) / 32t = (327 ± √23265) / 32t = (327 ± 152.5) / 32t = 13.3438 seconds or t = 19.5938 seconds.
.To find the time when the object is traveling up as well as down, we need to find the time at which the cannonball reaches its maximum height which can be obtained using the formula:
-b/2a = -327/32= 10.21875 s
Thus, the object is traveling up and down after 10.2 seconds. The answer is 10.2 seconds. The time taken to hit the ground can be determined by equating h to 0 and solving the quadratic equation obtained.
This is given by:16t² + 327t + 13 = 0
Using the quadratic formula:
t = (-b ± √(b² - 4ac)) / (2a)
t = (-327 ± √(327² - 4(16)(13))) / (2(16))
t = (-327 ± √104329) / 32
t = (-327 ± 322.8) / 32
