Find an explicit formula for Fibonacci numbers, where the recurrence relation for In = {n-1 + fn-2, where fo = 0, fi = 1. 11. Solve the following recurrence relations (a) On=7an-1 -10am-2. (b) Qn=2

Answers

Answer 1

The solution to the recurrence relation is:

[tex]Qn = (1/2)(2^n) - (1/2)[/tex]

To find an explicit formula for the Fibonacci sequence, we first write out the first few terms:

[tex]f0 = 0[/tex]

[tex]f1 = 1[/tex]

[tex]f2 = 1[/tex]

[tex]f3 = 2[/tex]

[tex]f4 = 3[/tex]

[tex]f5 = 5[/tex]

[tex]f6 = 8[/tex]

...

We notice that each term is the sum of the two preceding terms. Therefore, we can write:

[tex]fn = fn-1 + fn-2[/tex]

Let's solve this recurrence relation to find an explicit formula for the nth term. First, we write out the first few terms in terms of f1 and f0:

[tex]f2 = f1 + f0[/tex]

[tex]f3 = f2 + f1 = f1 + f0 + f1 = 2f1 + f0[/tex]

[tex]f4 = f3 + f2 = 3f1 + 2f0[/tex]

[tex]f5 = f4 + f3 = 5f1 + 3f0[/tex]

[tex]f6 = f5 + f4 = 8f1 + 5f0[/tex]

We can see that the coefficients of f1 and f0 are the Fibonacci numbers themselves (1, 1, 2, 3, 5, 8, ...). Therefore, we can write the explicit formula:

[tex]fn = (1/√5) [(1+√5)/2]^n - (1/√5) [(1-√5)/2]^n[/tex]

(a) To solve the recurrence relation [tex]On = 7On-1 - 10On-2[/tex], we first find the roots of the characteristic equation:

[tex]r^2 = 7r - 10[/tex]

[tex]r = (7 ± √(7^2 + 40))/2[/tex]

[tex]r1 = 5, r2 = -2[/tex]

Therefore, the general solution to the recurrence relation is:

[tex]On = c1(5^n) + c2(-2^n)[/tex]

We can find the values of c1 and c2 by using the initial conditions:

[tex]O0 = 1, O1 = 5[/tex]

[tex]c1 + c2 = 1[/tex]

[tex]5c1 - 2c2 = 5[/tex]

Solving these equations, we get:

[tex]c1 = 1, c2 = -1/3[/tex]

Therefore, the solution to the recurrence relation is:

On = 5^n - (1/3)(-2)^n

(b) To solve the recurrence relation Qn [tex]= 2Qn-1 + 1[/tex], we first find the root of the characteristic equation:

[tex]r - 2 = 0[/tex]

[tex]r = 2[/tex]

Therefore, the general solution to the recurrence relation is:

Qn = c(2^n) + d

We can find the values of c and d using the initial conditions:

[tex]Q0 = 0, Q1 = 1[/tex]

[tex]c + d = 0[/tex]

[tex]2c + d = 1[/tex]

Solving these equations, we get:

[tex]c = 1/2, d = -1/2[/tex]

Therefore, the solution to the recurrence relation is:

Qn [tex]= (1/2)(2^n) - (1/2)[/tex]

Larry has 25 goldfish and 15 minnows. He wants to put them in tanks so that there is the same number of goldfish and the same number of minnows in each tank. He wants to have the greatest amount of tanks possible. How many goldfish and how many willows will be in each tank?

Answers

Larry can have 5 tanks of goldfish and 3 tanks of minnows, with 5 goldfish and 5 minnows in each tank.

To find out how many goldfish and how many minnows will be in each tank, we need to find the greatest common divisor (GCD) of 25 and 15, which represents the largest number of fish that can be evenly divided into both groups.

The prime factorization of 25 is 55, and the prime factorization of 15 is 35, so the GCD of 25 and 15 is 5.

This means that Larry can put 5 goldfish and 5 minnows in each tank, and he will have:

25 / 5 = 5 tanks of goldfish

15 / 5 = 3 tanks of minnows

So Larry can have 5 tanks of goldfish and 3 tanks of minnows, with 5 goldfish and 5 minnows in each tank.

recall the equation for a circle with center (h,k)and radius r. at what point in the first quadrant does the line with equation y

Answers

The equation for a circle with centre (h,k) and radius r is (x-h)^2 + (y-k)^2 = r^2. To find the point where the line with equation y = mx intersects the circle in the first quadrant, we can substitute y = mx into the equation for the circle.

(x-h)^2 + (mx-k)^2 = r^2
Expanding and simplifying:
x^2 - 2hx + h^2 + m^2x^2 - 2kmx + k^2 = r^2
Grouping the x terms:
(1 + m^2)x^2 - 2(h+km)x + h^2 + k^2 - r^2 = 0
This is a quadratic equation in x, which we can solve using the quadratic formula:
x = [2(h+km) ± sqrt(4(h+km)^2 - 4(1+m^2)(h^2+k^2-r^2))] / 2(1+m^2)
Simplifying:
x = (h+km) ± sqrt[(h+km)^2 - (h^2+k^2-r^2)m^2] / (1+m^2)
Since we're looking for a point in the first quadrant, we want the positive solution for x. Once we find x, we can plug it back into y = mx to get the y-coordinate of the point.
Note that there may be 0, 1, or 2 solutions depending on the specific values of h, k, r, and m. If there are 2 solutions, one will be in the first quadrant and the other in the fourth quadrant. If there is 1 solution, it will be on the border between the first and fourth quadrants. If there are 0 solutions, the line does not intersect the circle in the first quadrant.

Calculate the RDA for protein for a 187# man. If he consumes one serving of Fattoush, How many more grams of protein should he have during the rest of the day? (Round to tenth) RDA = Rest of Day = 3. Topping one serving of Fattoush with 3 oz of grilled chicken adds 130 calories, 25g of protein, 1g of carbohydrates, and 3g of fat. How does that change the percents you calculated in #1? What is he percent increase in total calories? (Round to tenth of a percent.) Fat = Carbs =

Answers

According to the given information :

(1) 2% of the calories in one serving of Fattoush come from carbohydrates.

(2) If the man consumes one serving of Fattoush, which contains 21.39g of protein, he still needs to consume an additional 46.45g of protein during the rest of the day.

1. To calculate the percent of Fattoush calories that comes from fat and carbohydrates, we need to know the total number of calories in one serving of Fattoush. Let's assume that the total number of calories in one serving of Fattoush is 200.

To calculate the percent of calories from fat:
- We know that 1g of fat = 9 calories, so if there are 21.39g of fat in one serving of Fattoush, we can multiply that by 9 to get the total number of calories from fat: 21.39g x 9 = 192.51 calories from fat.
- To calculate the percent of calories from fat, we can divide the total calories from fat (192.51) by the total number of calories in one serving of Fattoush (200) and then multiply by 100: (192.51 / 200) x 100 = 96.3%.

So, 96.3% of the calories in one serving of Fattoush come from fat.

To calculate the percent of calories from carbohydrates:
- We know that 1g of carbohydrates = 4 calories, so if there are 1g of carbohydrates in one serving of Fattoush, we can multiply that by 4 to get the total number of calories from carbohydrates: 1g x 4 = 4 calories from carbohydrates.
- To calculate the percent of calories from carbohydrates, we can divide the total calories from carbohydrates (4) by the total number of calories in one serving of Fattoush (200) and then multiply by 100: (4 / 200) x 100 = 2%.

So, 2% of the calories in one serving of Fattoush come from carbohydrates.

2. To calculate the RDA for protein for a 187# man, we need to convert his weight from pounds to kilograms:
- 187# / 2.205 = 84.8 kg
- RDA = 0.8g protein per kg of body weight
- RDA = 0.8 x 84.8 = 67.84g of protein

If the man consumes one serving of Fattoush, which contains 21.39g of protein, he still needs to consume an additional:
- 67.84g - 21.39g = 46.45g of protein during the rest of the day.

3. If we add 3 oz of grilled chicken to one serving of Fattoush, the new total calories would be:
- 200 (calories in one serving of Fattoush) + 130 (calories from 3 oz of grilled chicken) = 330 total calories

To calculate the new percentages of calories from fat and carbohydrates:
- We know that 1g of fat = 9 calories, so if there are now 24.39g of fat in the dish (21.39g from the Fattoush and 3g from the chicken), we can multiply that by 9 to get the total number of calories from fat: 24.39g x 9 = 219.51 calories from fat.
- To calculate the percent of calories from fat, we can divide the total calories from fat (219.51) by the total number of calories in the dish (330) and then multiply by 100: (219.51 / 330) x 100 = 66.5%.

So, the percent of calories from fat has decreased from 96.3% to 66.5%.

- We know that there is 1g of carbohydrates in one serving of Fattoush and 1g of carbohydrates in the chicken, so the total number of calories from carbohydrates is: 1g x 4 = 4 calories from carbohydrates.
- To calculate the percent of calories from carbohydrates, we can divide the total calories from carbohydrates (4) by the total number of calories in the dish (330) and then multiply by 100: (4 / 330) x 100 = 1.2%.

So, the percent of calories from carbohydrates has slightly decreased from 2% to 1.2%.

The percent increase in total calories is:
- We know that the original total number of calories in one serving of Fattoush was 200.
- We added 130 calories from the chicken.
- The percent increase in total calories is (130 / 200) x 100 = 65%.

b. (15 pts.) Consider the following proposal of an outside consultant: The first partner is to

partners) accept this proposal and initiate the project?

Answers

a)  the risk-neutral partner wishes to initiate the project, but the risk-averse partner uses their veto power to block it.

b) with the proposed compensation of 50, both partners would accept the proposal and initiate the project.

a. We can calculate the expected payoff of the project as follows:

E(Payoff) = πH - C(1-π)

Substituting the given values, we get:

E(Payoff) = (1/2)(2000) - 900

E(Payoff) = 100

The risk-neutral partner would initiate the project because the expected payoff is positive. However, the risk-averse partner would use their veto power to block the project because they are risk-averse and the expected payoff is not guaranteed.

b. Let's calculate the expected payoff for each partner with the proposed compensation:

For the risk-neutral partner, the expected payoff becomes:

E(Payoff1) = π(H - 50) - C(1 - π)

Substituting the given values, we get:

E(Payoff1) = (1/2)(1950) - 900

E(Payoff1) = 75

For the risk-averse partner, the expected payoff becomes:

E(Payoff2) = πH - C(1 - π) + 50(1 - π)

Substituting the given values, we get:

E(Payoff2) = (1/2)(2000) - 900 + 50(1/2)

E(Payoff2) = 125

Both partners would accept the proposal and initiate the project because the expected payoff for each partner is positive. The risk-averse partner is willing to accept the proposal because the compensation of 50 in case of failure reduces their risk, resulting in a positive expected payoff.

To calculate the total amount Karl will pay to the bank, we need to find the monthly payment and then multiply it by the total number of payments over three years.

First, we need to calculate the monthly interest rate. Since the loan is compounded monthly, we divide the annual interest rate by 12:

Monthly interest rate = 7.25% / 12 = 0.006041667

Next, we need to calculate the total number of payments Karl will make over the course of the loan. Since he will be making monthly payments for three years, there will be a total of:

Total number of payments = 3 years x 12 months/year = 36 payments

To calculate the monthly payment, we can use the formula for the present value of an annuity:

Monthly payment = P * (r / (1 - (1 + r)^(-n)))

where P is the principal amount (in this case, $5000), r is the monthly interest rate, and n is the total number of payments.

Plugging in the values, we get:

Monthly payment = [tex]5000 * \frac{0.006041667}{(1-(1+0.006041667^{-36} )} = $154.96[/tex]

Finally, we can calculate the total amount Karl will pay to the bank by multiplying the monthly payment by the total number of payments:

Total amount paid = Monthly payment x Total number of payments = $154.96 x 36 = $5,578.56

Therefore, the total amount Karl will pay to the bank is $5,578.56

Triangle DEF has vertices at D(−3, 5), E(−10, 4), and F(−2, 2). Triangle D′E′F′ is the image of triangle DEF after a reflection. Determine the line of reflection if F′ is located at (2, 2).

x = 2
y = 1
y-axis
x-axis

Answers

Answer:

Step-by-step explanation:To determine the line of reflection, we need to find the equation of the line that is equidistant from each vertex of the original triangle and the corresponding vertex of the reflected triangle.

First, let's find the coordinates of the image of each vertex under the reflection. Since F' is given as (2, 2), we can reflect F across the unknown line of reflection to find the image of D and E. The line of reflection must be equidistant from each of these pairs of corresponding points.

To reflect F across a vertical line, the x-coordinate of F' must be the same as that of F but with the opposite sign. The x-coordinate of F is -2, so the x-coordinate of its image F' must be 2. Similarly, the y-coordinate of F' is 2, which means that the line of reflection must pass through the point (2, 2).

To reflect D across the same line, we can draw a perpendicular bisector between D and its image D', which must intersect the line of reflection at a right angle. The midpoint of DD' lies on the line of reflection, and it is equidistant from D and D'. Using the midpoint formula, we find the midpoint of DD' to be ((-3+2)/2, (5+2)/2) = (-0.5, 3.5). Since this point lies on the line of reflection, we can use the point-slope form of a line to find the equation of the line passing through (2, 2) and (-0.5, 3.5):

(y - 2) = m(x - 2) (where m is the slope of the line of reflection)

Simplifying:

y - 2 = m(x - 2)

y = mx - 2m + 2

To find the value of m, we can use the fact that the midpoint of DE lies on the line of reflection as well. The midpoint of DE is ((-3-10)/2, (5+4)/2) = (-6.5, 4.5). Substituting these values into the equation of the line, we get:

4.5 = m(-6.5) - 2m + 2

2.5 = -8.5m

m = -0.294

Therefore, the equation of the line of reflection is:

y = -0.294x + 2.588

This line is not the x-axis, y-axis or the line y=x. Therefore, the line of reflection is neither the x-axis nor the y-axis, and it is not the line y = x.

Bruce Lovegren was born on September 27, 1950. On April 14, 1977, he purchased a $15,000 10-year term life insurance policy. What was the annual premium he paid?

Answers

Bruce Lovegren paid a monthly annual premium of $125 for his $15,000 10-year term life insurance policy.

The monthly premium can be calculated by dividing the total cost of the policy by the number of months in the policy term:

monthly premium = total cost of policy / number of months in policy term

The total cost of the policy can be calculated by multiplying the annual premium by the number of years in the policy term:

total cost of policy = annual premium * number of years in policy term

The number of months in a year is 12.

Bruce Lovegren purchased the policy on April 14, 1977, so the policy was in effect for 10 years and 8 months, or 128 months.

The annual premium as follows:

total cost of policy = $15,000

number of years in policy term = 10

annual premium = total cost of policy / number of years in policy term

annual premium = $15,000 / 10

annual premium = $1,500

monthly premium = annual premium / 12

monthly premium = $1,500 / 12

monthly premium = $125

Answers

The maximum profit occurs when 34 offices are painted per month, and the maximum profit is R13500.

Based on the given information, Brush Pro is an one-man paint business owned by Banele and their monthly profit, P, depends on the number of offices painted per month, x. The profit function is given as P(x) = -x + 27x^2 + 132x + 2970, where 0 < x < 34.

To find the maximum profit, we need to find the vertex of the parabolic function. The vertex is located at x = -b/2a, where a = 27, b = 132.

x = -132/(2*27) = -2.44

Since x must be between 0 and 34, the maximum profit will occur at x = 0 or x = 34. We need to evaluate P(0) and P(34) to determine which one is the maximum.

P(0) = -0 + 27(0)^2 + 132(0) + 2970 = 2970
P(34) = -34 + 27(34)^2 + 132(34) + 2970 = 13500

Therefore, the maximum profit occurs when 34 offices are painted per month, and the maximum profit is R13500.

A cubical container is 4/5 filled with water. It contains 2.7l of water. Find the base area of the container

Answers

Answer:

225 cm²

Step-by-step explanation:

The container has 2.7L of water in it but it is only 4/5 full

Therefore if the container were to be filled entirely with water  it would contain
2.7 x 5/4 = 3.375 Liters

This, therefore is the volume of the container is 3.375 L
3.375 L = 3.375 x 1000 cm³
             =  3, 375 cm³

The volume of a cube of side a is given by
V = a³

The base area of a cube of side a is given by
A = a²

We have calculated the volume of the cube as 3.375 cm³

Therefore each side of the cubical container
[tex]a = \sqrt[3]{3375} = 15[/tex] cm

The base area is
a² = 15²

Answers

a) A nonzero element X in W is:

X = [ -10  -4 ]
       [   8    6 ]

b) The matrix Y is in V because it's a symmetric 2x2 matrix, but it's not in W since it can't be formed by any linear combination of matrix A.



a. To find a nonzero element X in W, we need to find a linear combination of the given matrix in the span of W. Let's denote the given matrix as A:

A = [ -5  -2 ]
       [  4    3 ]

Since W = span{A}, a linear combination of A would be:

X = k * A

where k is any scalar value. Let's choose k = 2:

X = 2 * A = [ -10  -4 ]
                [   8    6 ]

So, a nonzero element X in W is:

X = [ -10  -4 ]
       [   8    6 ]

b. To find an element Y in V (the vector space of symmetric 2x2 matrices) that is not in W, we need a matrix that cannot be formed by any linear combination of the given matrix A.

A symmetric 2x2 matrix has the form:

Y = [ a  b ]
       [ b  c ]

Let's choose a symmetric matrix that doesn't have the same pattern as A. For example:

Y = [ 1  2 ]
       [ 2  1 ]

This matrix Y is in V because it's a symmetric 2x2 matrix, but it's not in W since it can't be formed by any linear combination of matrix A.

Based on the Normal model N( 100, 15) describing IQ scores, what percent of people's IQs would you expect to be a) over 80? b) under 90? c) between 112 and 132?

Answers

The percentage of people's IQ over 80 is 9.18%, the percentage of people's IQ under 90 is 25.14% and the percentage of people's IQ between 112 and 132 is 8.23%
Then,
a) Over 80:
The z-score for 80 is (80-100)/15 = -1.33
Using a standard normal distribution table , we can evaluate that the area under the normal curve to the right of -1.33 is approximately 0.9082.
Therefore, the percentage of people's IQs that will be over 80 is approximately
(1-0.9082) x 100%
= 9.18%.

b) Under 90:
The z-score for 90 is (90-100)/15 = -0.67
Using a standard normal distribution table, we can evaluate that the area under the normal curve to the left of -0.67 is approximately 0.2514.
Therefore, the percentage of people's IQs that will be under 90 is approximately
0.2514 x 100%
= 25.14%.
c) Between 112 and 132:
The z-score for 112 is (112-100)/15 = 0.8
The z-score for 132 is (132-100)/15 = 2.13
Using a standard normal distribution table, we can calculate that the area under the normal curve between these two z-scores is approximately 0.0823.
Therefore, the percentage of people's IQs that will be between 112 and 132 is approximately
0.0823 x 100%

The tables are completed as follows:

Table 1: f(x) = 30.Table 2: f(x) = 1.301.

How to complete the table?

For Table 1, we have an exponential function defined as follows:

f(x) = b^x.

We have that when x = 0.699, f(x) = 5, hence the base b is obtained as follows:

b^0.699 = 5

b = 5^(1/0.699)

b = 10.

Hence, when x = 1.477, the value of f(x) is given as follows:

f(x) = 10^1.477

f(x) = 30.

Table 2 is the inverse of table 1. For Table I, we have that when x = 1.301, f(x) = 20, hence for table 2, we have that f(x) = 1.301 when x = 20.
