So, the recursive formula for H(n) is:
H(1) = 2
H(n) = H(n-1) + 12
A recursive formula is one that defines each term in a series by reference to the phrase(s) that came before it. The first term, or firsts, in the series must always be stated in recursive formulae. A recursive algorithm is one that uses "smaller (or simpler)" input values to call itself and gets the result for the current input by performing straightforward operations on the value that was returned for the smaller (or simpler) input.
And the Fibonacci sequence is the most well-known recursive formula. The following is the Fibonacci sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21,… Keep in mind that each number in the series is the product of the two numbers before it. For instance, the total of the two terms before it, 5 and 8, is 13.
Recursive formula for H(n), we need to find the first term and the common difference.
H(1) = -10 + 12(1) = 2
H(2) = -10 + 12(2) = 14
The common difference between H(1) and H(2) is 14 - 2 = 12.

A father and his three children decide on all matters with a vote. Each member of the family gets as many votes as their age. Right now, the family members are 36,13,6, and 4 year old, so the father always wins. How many years will it take for the three children to win a vote if they all agree?
It would take the three children a total of 19 years to have a combined total of 37 votes, assuming they all agree on a particular matter, but this assumes no new family members and the father's age remains constant.
The family's voting system is based on the principle of giving equal representation to each member of the family, with each person getting as many votes as their age. However, in the current situation, the father's age of 36 gives him an overwhelming advantage over the rest of the family. In any vote, he will always win since he has more votes than the three children combined.
To determine how many years it will take for the children to win a vote, we need to examine the age distribution of the family. Currently, the father's age is 36, while the children's ages are 13, 6, and 4. Thus, the father has a total of 36 votes, while the three children have a combined total of 23 votes (13 + 6 + 4).
Assuming that the children all agree on a particular matter, they would need to have a total of 37 votes to win a vote, since this would be a majority of the family's total voting power of 59 (36 + 13 + 6 + 4).
Therefore, we can calculate the number of years it would take for the children to have a total of 37 votes by adding their current ages to the number of years it would take for each child to gain an additional vote. For the 13-year-old, this would be 1 year, for the 6-year-old, this would be 8 years, and for the 4-year-old, this would be 10 years.
Adding up the years required for each child, we get a total of 19 years. Therefore, it would take 19 years for the children to have a combined total of 37 votes, assuming they all agree on a particular matter. However, this assumes that the father's age remains constant, and no new members join the family.

1. An example of a country with a poor foreign exchange rate policy is Argentina during the early 2000s.
From 1991 to 2001, Argentina implemented a currency board system where the Argentine peso was pegged to the US dollar at a fixed exchange rate of 1:1. This policy led to several mistakes and eventually resulted in a financial crisis:
- Mistakes made: The currency board system limited the government's ability to manage the money supply and respond to economic shocks. Also, the overvalued peso made Argentina's exports more expensive, which hurt the competitiveness of its industries.
- What happened as a result: Argentina faced a severe recession, high unemployment, and a massive public debt. In December 2001, the country defaulted on its debt, leading to a currency crisis and the abandonment of the currency board system. The peso depreciated sharply, causing severe economic hardship for the population.

1. 3x + 4y = 12; 2x – 3y = 6
2. x + y = 3; x – y = 5
3. 3x + 2y – z = 4; 2x – y + 3z = 4; x + y + 2z = 4
4. x – y + 5z = -4; 4x – 2y + 3z = 1; 3x – 2y + 6z = 6
5. x2 + y2 = 13; 2x – 3y = -5
6. 5x2 + y2 = 14; 3x2 – 2y2 = -15
7. 2x2 + 5x – 4y = 3; 3x2 – 3x + 2y2 = 2
Answer: Example 2: Solve the system of equations with augmented matrices using the Gauss-Jordan elimination method. x – 3z = – 2. 2x + 2y + z = 4. 3x + y – 2z = 5.
Step-by-step explanation:
Answer:
3x + 4y = 12; 2x – 3y = 6
Multiplying the first equation by 2 and the second equation by 3, we get:
6x + 8y = 24
6x - 9y = 18
Subtracting the second equation from the first, we get:
17y = 6
y = 6/17
Substituting y in the first equation, we get:
3x + 4(6/17) = 12
3x = 180/17 - 24/17
3x = 156/17
x = 52/17
Therefore, the solution of the given system is x = 52/17 and y = 6/17.
x + y = 3; x – y = 5
Adding the two equations, we get:
2x = 8
x = 4
Substituting x in the first equation, we get:
4 + y = 3
y = -1
Therefore, the solution of the given system is x = 4 and y = -1.
3x + 2y – z = 4; 2x – y + 3z = 4; x + y + 2z = 4
Adding the first and second equations, we get:
5x + y + 2z = 8
Subtracting the third equation from the above equation, we get:
4x + z = 4
Substituting z = 4 - 4x in the third equation, we get:
3x + 2y - (4 - 4x) = 4
7x + 2y = 8
Substituting y = (8 - 7x)/2 in the first equation, we get:
9x - z = 8
Substituting z = 4 - 4x, we get:
x = 4/5, y = 2/5, and z = 4/5
Therefore, the solution of the given system is x = 4/5, y = 2/5, and z = 4/5.
x – y + 5z = -4; 4x – 2y + 3z = 1; 3x – 2y + 6z = 6
Multiplying the first equation by -4 and adding it to the second equation, we get:
16x - 6z = 17
Multiplying the first equation by -3 and adding it to the third equation, we get:
9x + 4z = 18
Multiplying the second equation by 2 and subtracting it from the third equation, we get:
x + 6z = 8
Substituting z = (8 - x)/6 in the above equation, we get:
x = 10/3, y = 8/3, and z = 2/3
Therefore, the solution of the given system is x = 10/3, y = 8/3, and z = 2/3.
x2 + y2 = 13; 2x – 3y = -5
Squaring the second equation and simplifying, we get:
4x2 - 12xy + 9y2 = 25
Adding the above equation to the first equation, we get:
5x2 + 10y2 = 38

a closed cylindrical can has a fixed surface area s. find the ratio of its height to the diameter of its base that maximizes its volume.
The ratio of the height to the diameter that maximizes the volume of the cylindrical can is: 0.886 approximately.
Let the radius of the cylindrical can be denoted by r, and its height by h. The surface area of the can is given by:
S = 2π[tex]r^2[/tex]+ 2πrh
Simplifying this expression, we get:
h = (S - 2π[tex]r^2[/tex])/(2πr)
The volume of the cylindrical can is given by:
V = π[tex]r^2[/tex]h
Substituting the expression for h obtained earlier, we get:
V = π[tex]r^2[/tex](S - 2π[tex]r^2[/tex])/(2πr)
Simplifying this expression, we get:
V = (S/2π - [tex]r^2[/tex])πr
To maximize the volume of the cylindrical can, we need to find the value of r that maximizes the above expression. We can do this by differentiating the expression with respect to r, setting it equal to zero, and solving for r:
dV/dr = (S/2π - [tex]2r^2[/tex])π = 0
Solving for r, we get:
r = √(S/4π)
Substituting this value of r back into the expression for h, we get:
h = (S - 4π[tex]r^2[/tex])/(4πr) = (S - S/2)/(2√(S/4π)) = √(Sπ)/2
Therefore, the ratio of the height to the diameter that maximizes the volume of the cylindrical can is:

(4) Show that there is a nonabelian group of order 63. (Hint: Re- view the example of a group of order 21 from class and see if a you can modify that to find a nonabelian group of order 63 €
(1,0) has order 1 in C7 and order 1 in C3, and (0,1) has order 7 in C7 and order 1 in C3, we see that ((1,0),(0,1)) has order 7 in G and ((1,0),(1,0)) has order 3 in G. Similarly, ((1,1),(0,1)) has order 7 in G and ((1,1),(1,1)) has order 3 in G.
The group of order 21 is isomorphic to the cyclic group C7 x C3. We can use this group to construct a nonabelian group of order 63 as follows:
Consider the direct product of two groups of order 21: G = (C7 x C3) x (C7 x C3). Since the direct product of two abelian groups is also abelian, we know that G is not abelian if and only if it contains non-commuting elements.
Define two elements a = ((1,0),(0,1)) and b = ((1,1),(0,1)) in G. It can be shown that a and b have orders 3 and 7, respectively, and that they do not commute. Therefore, G is nonabelian.
To see why a and b have orders 3 and 7, respectively, note that the order of (g,h) in G is equal to the least common multiple of the orders of g and h in their respective groups. Since (1,0) has order 1 in C7 and order 1 in C3, and (0,1) has order 7 in C7 and order 1 in C3, we see that ((1,0),(0,1)) has order 7 in G and ((1,0),(1,0)) has order 3 in G. Similarly, ((1,1),(0,1)) has order 7 in G and ((1,1),(1,1)) has order 3 in G.

(5) Solve the IVP dY dt - [] 70- = [3] [10 -1 5 8 Y, Y(0) =
The solution to the IVP is Y(t) = [ -5e^(4t) - 5e^(-t); 3e^(4t) - e^(-t)] with initial condition Y(0) = [5; 3].
To solve the IVP dY/dt - [3 10; -1 5] Y = [8; 0] with initial condition Y(0) = [5; 3], we can use the matrix exponential method.
First, we need to find the eigenvalues and eigenvectors of the matrix A = [3 10; -1 5]. We can do this by solving the characteristic equation det(A - λI) = 0, where I is the identity matrix and λ is the eigenvalue.
det(A - λI) = (3-λ)(5-λ) + 10 = λ^2 - 8λ + 25 = (λ-4)^2
So, the eigenvalue is λ = 4 with multiplicity 2. To find the eigenvectors, we need to solve (A - λI)x = 0 for each eigenvalue.
For λ = 4, we have
(A - λI)x = [3 10; -1 5 - 4] [x1; x2] = [0; 0]
which gives us the equation 3x1 + 10x2 = 0 and -x1 + x2 = 0. Solving these equations, we get x1 = -10/3 and x2 = 1. So, the eigenvector corresponding to λ = 4 is [ -10/3; 1].
Since we have repeated eigenvalues, we need to find the generalized eigenvector. We can do this by solving (A - λI)x = v, where v is any vector that is not an eigenvector.
Let v = [1; 0], then (A - 4I)x = [1; 0] gives us 3x1 + 10x2 = 1 and -x1 + x2 = 0. Solving these equations, we get x1 = -2/3 and x2 = 1/3. So, the generalized eigenvector corresponding to λ = 4 is [ -2/3; 1/3].
Now, we can form the matrix P = [ -10/3 -2/3; 1 1/3] and the diagonal matrix D = [4 1; 0 4], where the diagonal entries are the eigenvalues.
Using the formula Y(t) = e^(At) Y(0), we can write Y(t) as
Y(t) = P e^(Dt) P^(-1) Y(0)
= [ -10/3 -2/3; 1 1/3] [ e^(4t) 0; 0 e^(4t)] [ -1/2 1/2; 2 1] [5; 3]
= [ -5e^(4t) - 5e^(-t); 3e^(4t) - e^(-t)]
Therefore, the solution to the IVP is Y(t) = [ -5e^(4t) - 5e^(-t); 3e^(4t) - e^(-t)] with initial condition Y(0) = [5; 3].

Problem 4 * (15 pts): Salty "Game" You are given 100 cups of water, each labeled from 1 to 100. Unfortunately, one of those cups is actually really salty water! You will be given cups to drink in the order they are labeled. Afterwards, the cup is discarded and the process repeats. Once you drink the really salty water, this "game" stops.
i. What is the probability that the ith cup you are given has really salty water? Either show the work to calculate your probability or explain why that is the case? ii. Suppose you are to be given 47 cups. On average, will you end up drinking the really salty water? (Hint: Define X to be the number of cups of water you drink, including the really salty water that ends the "game".)
i.the probability that the ith cup you are given has really salty water is 1/(101-i).
ii.on average, you will end up drinking the really salty water when given 47 cups of water.
i. The probability that the ith cup you are given has really salty water depends on the total number of cups and the position of the salty cup. Since there is only one salty cup, the probability that the first cup is salty is 1/100. The probability that the second cup is salty is 1/99 since there are now only 99 cups remaining and still only one salty cup. Similarly, the probability that the ith cup is salty is 1/(101-i). Therefore, i
ii. Let X be the number of cups of water you drink, including the really salty water that ends the "game". Since the probability that the ith cup is salty is 1/(101-i), the expected value of X can be calculated as:
E(X) = 1/100 + 1/99 + 1/98 + ... + 1/55 + 48
where 48 is added because you are guaranteed to drink the really salty water on the 48th cup.
the expected value of X is approximately 49.19 cups. Therefore, on average, you will end up drinking the really salty water when given 47 cups of water.

A research group developed the following mathematical model relating systolic blood pressure and age: P(x)=a+ bln(x+1). Where P(x) is pressure, measured in millimeters of mercury, and x is age in years. By examining Guilford County hospital records, they estimate the values for Guilford County to be a=43 and b=25. Using this model, estimate the rate oI change of pressure with respect to time after 31 years. Round to the nearest hundredth ( 2 decimal places). ____ millimeters per year
Rounding to two decimal places, the rate of change of blood pressure with respect to time after 31 years is approximately 0.81 millimeters per year.
The mathematical model relating systolic blood pressure and age is given as P(x)=a+b*ln(x+1), we can differentiate it with respect to time (t) to find the rate of change of pressure with respect to time:
dP/dt = dP/dx * dx/dt
Here dx/dt is the rate of change of age with respect to time, which is simply 1 year per year or 1.
Taking the derivative of P(x) with respect to x, we get:
dP/dx = b/(x+1)
Substituting the given values for a and b, we have:
P(x) = 43 + 25ln(x+1)
dP/dx = 25/(x+1)
Therefore, the rate of change of pressure with respect to time after 31 years is:
dP/dt = dP/dx * dx/dt = (25/(31+1)) * 1 = 0.8065

(b) Determine the mean of this distribution:
(c) Determine the standard deviation of this distribution:
(d) Probability of (x > 227) =
(e) Probability of (202 <= x <= 219) =
(f) Probability of (x <= 222) =
a) The value of f(x) is 1/51, for 193 ≤ x ≤ 244
b) The mean is 218.5
c) σ = = 17.65
d) P(x > 227) = 0.333
e) P(202 ≤ x ≤ 219) = 0.333
f) P(x ≤ 222) = 0.569
We have,
a)
Since the distribution is uniform, the probability density function (PDF) is constant within the range [193, 244] and zero elsewhere.
The PDF is given by:
f(x) = 1 / (244 - 193) = 1/51, for 193 ≤ x ≤ 244
b)
The mean of a uniform distribution is the average of the minimum and maximum values, so we have:
mean = (193 + 244) / 2 = 218.5
c)
The standard deviation of a uniform distribution is given by:
σ = (b - a) / √12
where a and b are the minimum and maximum values, respectively. Substituting in the values given, we get:
σ = (244 - 193) / √12 = 17.65
d)
The probability of x > 227 is the area under the PDF to the right of x = 227. Since the PDF is constant, this is simply the proportion of the total range that lies to the right of 227:
P(x > 227) = (244 - 227) / (244 - 193) = 17 / 51 ≈ 0.333
e)
The probability of 202 ≤ x ≤ 219 is the area under the PDF between x = 202 and x = 219. This is:
P(202 ≤ x ≤ 219) = (219 - 202) / (244 - 193) = 17 / 51 ≈ 0.333
f)
The probability of x ≤ 222 is the area under the PDF to the left of x = 222. This is:
P(x ≤ 222) = (222 - 193) / (244 - 193) = 29 / 51 ≈ 0.569
Thus,
a) f(x) = 1/51, for 193 ≤ x ≤ 244
b) mean = 218.5
c) σ = = 17.65
d) P(x > 227) = 0.333
