Extra Credit: A theorem states: \( \mathrm{F} \) is a Fibonacci number if and only if either \( 5 F^{2}+4 \) or \( 5 F^{2}-4 \) is a perfect square, test this theorem for the FNs (a) 8 and (b) 13

Answers

The theorem that states F is a Fibonacci number if and only if either 5 F2+4 or 5 F2−4 is a perfect square was tested for FNs 8 and 13. However, the theorem was not valid for either of these numbers.

We know that a sequence of numbers is called a Fibonacci series if the next number in the sequence is the sum of the two previous ones.

The first two numbers of the Fibonacci series are 0 and 1.

Hence, the third number is 0 + 1 = 1,

fourth number is 1 + 1 = 2,

fifth number is 1 + 2 = 3, and so on.

Let's test this theorem for the FNs (a) 8 and (b) 13.

We have to verify whether either 5 F^{2}+4  or 5 F^{2}-4  is a perfect square.

For FN = 8,

5F^{2}+4 = 5(8)^2+4 = 324 and 5 F^{2}-4 = 5(8)^2-4 = 316.

Neither of these is a perfect square.

Hence, the theorem is not valid for FN = 8.

For FN = 13,5

F^{2}+4 = 5(13)2+4 = 876 and 5 F^{2}-4 = 5(13)2-4 = 860.

Neither of these is a perfect square. Hence, the theorem is not valid for FN = 13.

Therefore, the theorem is not valid for FNs 8 and 13.

The theorem that states F is a Fibonacci number if and only if either 5 F2+4 or 5 F2−4 is a perfect square was tested for FNs 8 and 13. However, it was found that the theorem was not valid for either of these numbers.

A triangle is rightangled triangle if ad = 12 bd = dc then find the length of bd and dc

Answers

The length of bd (and dc) is approximately 8.49 units.

To find the length of bd and dc in a right-angled triangle with ad = 12, we can use the Pythagorean theorem. In a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Let's label the sides of the triangle as follows:
- ad is the hypotenuse
- bd is one of the legs
- dc is the other leg

Using the Pythagorean theorem  we have the equation:
(ad)² = (bd)² + (dc)²

Given that ad = 12, we can substitute it into the equation:
(12)² = (bd)² + (dc)²

Simplifying further:
144 = (bd)² + (dc)²

Since bd = dc (as mentioned in the question), we can substitute bd for dc:
144 = (bd)² + (bd)²

Combining like terms:
144 = 2(bd)²

Dividing both sides by 2:
72 = (bd)²

Taking the square root of both sides:
bd = √72
Simplifying:
bd ≈ 8.49
Therefore, the length of bd (and dc) is approximately 8.49 units.

After a \( 80 \% \) reduction, you purchase a new television on sale for \( \$ 184 \). What was the original price of the television? Round your solution to the nearest cent. \( \$ \)

Answers

Percent Discount = 80%. As expected, we obtain the same percentage discount that we were given in the problem.

 Suppose that the original price of the television is x. If you get an 80% discount, then the sale price of the television will be 20% of the original price, which can be expressed as 0.2x. We are given that this sale price is $184, so we can set up the equation:

0.2x = $184

To solve for x, we can divide both sides by 0.2:

x = $920

Therefore, the original price of the television was $920.

This means that the discount on the television was:

Discount = Original Price - Sale Price

Discount = $920 - $184

Discount = $736

The percentage discount can be found by dividing the discount by the original price and multiplying by 100:

Percent Discount = (Discount / Original Price) x 100%

Percent Discount = ($736 / $920) x 100%

Percent Discount = 80%

Answers

The evaluated expression -56.143 / 7.16, rounded to the correct number of significant figures, is -7.84.

To evaluate the expression -56.143 / 7.16 to the correct number of significant figures, we need to follow the rules for significant figures in division.

In division, the result should have the same number of significant figures as the number with the fewest significant figures in the expression.

In this case, the number with the fewest significant figures is 7.16, which has three significant figures.

Performing the division:

-56.143 / 7.16 = -7.84120838...

To round the result to the correct number of significant figures, we need to consider the third significant figure from the original number (7.16). The digit that follows the third significant figure is 8, which is greater than 5.

Therefore, we round up the third significant figure, which is 1, by adding 1 to it. The result is -7.842.

Since we are evaluating to the correct number of significant figures, the final answer is -7.84 (option C).

Lizzie cuts of 43 congruent paper squares. she arranges all of them on a table to create a single large rectangle. how many different rectangles could lizzie have made? (two rectangles are considered the same if one can be rotated to look like the other.)

Answers

Lizzie could have made 1 rectangle using 43 congruent paper squares, as the factors of 43 are prime and cannot form a rectangle. Combining pairs of factors yields 43, allowing for rotation.

To determine the number of different rectangles that Lizzie could have made, we need to consider the factors of the total number of squares she has, which is 43. The factors of 43 are 1 and 43, since it is a prime number. However, these factors cannot form a rectangle, as they are both prime numbers.

Since we cannot form a rectangle using the prime factors, we need to consider the factors of the next smallest number, which is 42. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.

Now, we need to find pairs of factors that multiply to give us 43. The pairs of factors are (1, 43) and (43, 1). However, since the problem states that two rectangles are considered the same if one can be rotated to look like the other, these pairs of factors will be counted as one rectangle.

Answers

To find the derivative of the given function \( f(x) = (x^4 - 3x^2 + 4x + 1)(x^3 + x^2 - 4) \), we use the product rule. The derivative of the function can be expressed as \( F' = (x^4 - 3x^2 + 4x + 1)(x^3 + x^2 - 4)' + (x^4 - 3x^2 + 4x + 1)'(x^3 + x^2 - 4) \).

The derivative of a product of two functions can be obtained using the product rule, which states that the derivative of the product of two functions \( u(x) \) and \( v(x) \) is given by \( (u(x)v(x))' = u'(x)v(x) + u(x)v'(x) \).

Applying the product rule to the given function, we have:

\( F' = (x^4 - 3x^2 + 4x + 1)(x^3 + x^2 - 4)' + (x^4 - 3x^2 + 4x + 1)'(x^3 + x^2 - 4) \)

To find the derivative of each term, we can use the power rule and the sum rule. The power rule states that the derivative of \( x^n \) with respect to \( x \) is \( nx^{n-1} \), and the sum rule states that the derivative of the sum of two functions is the sum of their derivatives.

The first term, \( (x^4 - 3x^2 + 4x + 1)(x^3 + x^2 - 4)' \), involves the derivative of \( (x^3 + x^2 - 4) \). Applying the power rule, we have:

\( (x^3 + x^2 - 4)' = 3x^2 + 2x \)

The second term, \( (x^4 - 3x^2 + 4x + 1)'(x^3 + x^2 - 4) \), involves the derivative of \( (x^4 - 3x^2 + 4x + 1) \). Again, applying the power rule, we have:

\( (x^4 - 3x^2 + 4x + 1)' = 4x^3 - 6x + 4 \)

Substituting these derivatives back into the expression, we obtain:

\( F' = (x^4 - 3x^2 + 4x + 1)(3x^2 + 2x) + (4x^3 - 6x + 4)(x^3 + x^2 - 4) \)

Hence, the derivative of the given function is \( F' = (x^4 - 3x^2 + 4x + 1)(3x^2 + 2x) + (4x^3 - 6x + 4)(x^3 + x^2 - 4) \

The solution for this system of equations is x = -1134 and y = 1080.To find the value of each variable in the given equations, we'll equate the corresponding elements on both sides.

[2x 0] = [y 4 0], Equating the elements: 2x = y, 0 = 4. Since the second equation, 0 = 4, is not true, there is no solution for this system of equations. [x + 261y - 3] = [-561 -4]. Equating the elements: x + 261y = -561

-3 = -4. Again, the second equation, -3 = -4, is not true. Therefore, there is no solution for this system of equations. [1-247 - 32z + 4] = [1y -52x -47 -33z - 1]. Equating the elements: 1 - 247 = 1-32z + 4 = y-52x - 47 = -33z - 1

The first equation simplifies to 1 - 247 = 1, which is not true. Thus, there is no solution for this system of equations. [x 21x + 2y] = [521 - 3]

Equating the elements:x = 5, 21x + 2y = 21, From the first equation, x = 5. Substituting x = 5 into the second equation: 21(5) + 2y = 21, 2y = -84, y = -42. The solution for this system of equations is x = 5 and y = -42. [x+y 1] = [2 1]. Equating the elements: x + y = 2, 1 = 1. The second equation, 1 = 1, is true for all values. From the first equation, we can't determine the exact values of x and y. There are infinitely many solutions for this system of equations. [0 x-y] = [0 8], Equating the elements:0 = 0, x - y = 8. The first equation is true for all values. From the second equation, we can't determine the exact values of x and y.

There are infinitely many solutions for this system of equations. [y 21 x + y] = [x + 2218]. Equating the elements: y = x + 2218, 21(x + y) = x. Simplifying the second equation: 21x + 21y = x, Rearranging the terms:

21x - x = -21y, 20x = -21y, x = (-21/20)y. Substituting x = (-21/20)y into the first equation: y = (-21/20)y + 2218. Multiplying through by 20 to eliminate the fraction: 20y = -21y + 44360, 41y = 44360, y = 1080. Substituting y = 1080 into x = (-21/20)y: x = (-21/20)(1080), x = -1134.

Wally has a $ 500 gift card that he want to spend at the store where he works. he get 25% employee discount , and the sales tax rate is 6.45% how much can wally spend before the discount and tax using only his gift card?

Answers

Wally has a gift card worth $500. Wally plans to spend the gift card at the store where he is employed. In the process, Wally can enjoy a 25% employee discount. Wally can spend up to $625 before applying the discount and tax when using only his gift card.

Let's find out the solution below.Let us assume that the amount spent before the discount and tax = x dollars. As Wally gets a 25% discount on this, he will have to pay 75% of this, which is 0.75x dollars.

This 0.75x dollars will include the sales tax amount too. We know that the sales tax rate is 6.45%.

Hence, the sales tax amount on this purchase of 0.75x dollars will be 6.45/100 × 0.75x dollars = 0.0645 × 0.75x dollars.

We can write an equation to represent the situation as follows:

Amount spent before the discount and tax + Sales Tax = Amount spent after the discount

0.75x + 0.0645 × 0.75x = 500

This can be simplified as 0.75x(1 + 0.0645) = 500. 1.0645 is the total rate with tax.0.75x × 1.0645 = 500.

Therefore, 0.798375x = 500.x = $625.

The equation for the reflected graph of f(x)=x^2 + 1 across the x-axis is f(x)=-x^2 - 1.

To reflect a graph across the x-axis, we need to negate the y-coordinates of all the points on the graph. In the original function f(x)=x^2 + 1, let's take a few sample points and calculate their reflections:

Point A: (0, 1)

Reflection of A: (0, -1)

Point B: (1, 2)

Reflection of B: (1, -2)

Point C: (-1, 2)

Reflection of C: (-1, -2)

By observing the pattern, we can see that reflecting across the x-axis negates the y-coordinate of each point. Therefore, the equation for the reflected graph is f(x)=-x^2 - 1.

Answers

The critical numbers of f(x) = (x^2 + 5)/(x + 2) are -2, -sqrt(5), and sqrt(5). A critical number of a function is a point in the function's domain where the derivative is either equal to zero or undefined.

To find the critical numbers of f(x), we need to find the derivative of f(x). The derivative of f(x) is: f'(x) = ((x + 2)(2x) - (x^2 + 5)) / ((x + 2)^2) = (2x^2 + 4x - 5) / ((x + 2)^2)

f'(x) = 0 when x = -2. f'(x) is also undefined when x = -2, so both of these points are critical numbers.

In addition to -2, the derivative of f(x) is also equal to zero when x = -sqrt(5) and x = sqrt(5). However, these points are not critical numbers because they are not in the domain of f(x). The domain of f(x) is all real numbers except for -2, so the only critical numbers of f(x) are -2, -sqrt(5), and sqrt(5).

The critical numbers of a function can be used to find the intervals where the function is increasing or decreasing. For example, f(x) is increasing on the interval (-sqrt(5), -2) and decreasing on the interval (-2, sqrt(5)).

The critical numbers of a function can also be used to find the relative extrema of the function. A relative maximum of a function is a point in the function's domain where the function changes from increasing to decreasing.

A relative minimum of a function is a point in the function's domain where the function changes from decreasing to increasing. In the case of f(x), the only relative extremum is a relative maximum at x = -sqrt(5).

Given that the radius of the cylinder is 4 feet and the height is 8 feet, substituting these values into the formula, we get

Surface area of the cylinder = 2πrh+2πr²= 2 × π × 4 × 8 + 2 × π × 4²= 64π + 32π= 96π or approximately 301.6 square feet.The surface area of a cylinder can be defined as the area that surrounds the cylinder including the top, bottom, and side. The surface area of a cylinder with a radius of 4 feet and a height of 8 feet is 301.6 square feet.

This is a useful measure as it helps in determining the amount of paint or material required to cover the cylinder. It is essential to note that the surface area of a cylinder is different from its volume as the surface area measures the amount of material needed to cover the cylinder while the volume measures the amount of space inside the cylinder. The surface area of a cylinder is used in several industries, including construction, manufacturing, and engineering.

Therefore, the surface area of a cylinder with radius 4 feet and height 8 feet is 301.6 square feet.

In 1957, a salary cap was introduced in the sports league to limit the amount of money spent on players' salaries. The quadratic model y = 0.2313x^2 + 2.600x + 35.17 provides an approximation of the salary cap in millions of dollars for the years 1997 to 2012. In this model, x represents the number of years after 1997. By plugging in the appropriate values of x into the equation, we can calculate the estimated salary cap for a specific year.

For example, when x = 0 (representing 1997), the equation simplifies to y = 35.17 million dollars, indicating that the estimated salary cap for that year was approximately 35.17 million dollars. Similarly, when x = 1 (representing 1998), the equation yields y = 38.00 million dollars. By following this pattern and substituting the corresponding x-values for each year from 1997 to 2012, we can estimate the salary cap for those years using the given quadratic model.

It is important to note that this model is an approximation and may not perfectly reflect the actual salary cap values. However, it provides a useful tool for estimating the salary cap based on the available data.

Ken's friends came over to share an extra large pizza. John said he ate 1/5 of the pizza, Jane said she ate only 1/6 of the pizza, and Jake ate 1/4 of the pizza. How much of the pizza is left for Ken? (answer should be a fraction) (2 pts )

Answers

The fraction of the pizza that is left for Ken is 23/60.

If John ate 1/5 of the pizza, Jane ate 1/6 of the pizza, and Jake ate 1/4 of the pizza, then the total fraction of the pizza that they ate can be found by adding the individual fractions:

1/5 + 1/6 + 1/4

To add these fractions, we need to find a common denominator. The least common multiple of 5, 6, and 4 is 60. Therefore, we can rewrite the fractions with 60 as the common denominator:

12/60 + 10/60 + 15/60

Adding these fractions, we get:

37/60

Therefore, the fraction of the pizza that was eaten by John, Jane, and Jake is 37/60.

To find the fraction of the pizza that is left for Ken, we can subtract this fraction from 1 (since 1 represents the whole pizza):

1 - 37/60

To subtract these fractions, we need to find a common denominator, which is 60:

60/60 - 37/60

Simplifying the expression, we get:

23/60

Therefore, the fraction of the pizza that is left for Ken is 23/60.

has an absolute maximum value and absolute minimum value subject to the constraint x 2
+xy+y 2
=81. Use Lagrange multipliers to find these values. The absolute maximum is (Type an exact answer in terms of e.)

Answers

The absolute maximum is  [tex]f(x,y) = e^{(18)}[/tex] and the absolute minimum is [tex]f(x,y) = e^{(-6\sqrt3)}.[/tex]

Use the method of Lagrange multipliers.

[tex]g(x,y) = x^2 + xy + y^2 - 81,[/tex]

then ∇f = λ∇g or ∇f = λ(2x + y, 2y + x)

= (2xy, 2xe^(2xy)), and ∇g = (2x + y, x + 2y).

Therefore, the system of equations to solve is:

2xy = λ(2x + y)x + 2y = λ(x + 2y) x^2 + xy + y^2 = 81

use the second equation to write y = λx + 2λy, which simplifies to

y(1 - 2λ) = λx, or x/y = (1 - 2λ)/λ.

Substituting this into the first equation yields:

2xy = λ(2x + y) ⇔ 2x^2(1 - 2λ)/λ

= λ(2x + x(1 - 2λ)/λ)⇔ 2x^2(1 - 2λ)

= 2λx(1 + 1 - 2λ)⇔ 2x(1 - 2λ)

= 2λ(2x - x(2λ - 1)/λ)⇔ 2x(1 - 2λ)

= 2λx(3 - 2λ)/λ⇔ (1 - 2λ)

= (3 - 2λ)/λ⇔ λ

= -1/4 or λ = 3

solve for x and y using the system of equations and substitute into f(x,y) to find the maximum and minimum values. When λ = -1/4,

x + 2y = (-1/4)(2x + y)

⇔ 9x + 18y = 0 or

x = -2y2xy = (-1/4)(2x + y)

⇔ -xy = (-1/8)(2x + y)

⇔ 2xy + xy = (x - y)/4

⇔ x - 3y = 0

or x = 3y

Substituting x = -2y into [tex]x^2 + xy + y^2 = 81[/tex]

[tex]4y^2 - 2y^2 + y^2 = 81[/tex]

⇔ y = ±3√3 or y = 3√3/2

The corresponding values of x and f(x,y) are:

x = -2y = ±6√3, f(x,y)

= -2y

= ±3√3,

[tex]f(x,y) = e^{(-27)}[/tex] for y = 3√3/2When λ = 3,

x + 2y = 3(2x + y)

⇔ x - y = 0 or x = y2xy = 3(2x + y)

⇔ 2xy = 6x + 3y

⇔ x = 2y

Substituting x = y into [tex]x^2 + xy + y^2 = 81[/tex]yields:

[tex]3y^2 = 81[/tex]

Solve the system using substitution 4x+9y= -24 -3x-3y= 18 x= _______ y= _______

Answers

To solve the given system of equation, by substituting the value of x from the second equation into the first equation, we can find the values of x and y. The solution to the system is x = -3 and y = 4.

We start by solving one of the equations for a variable in terms of the other variable. Let's solve the second equation for x:

-3x - 3y = 18

Adding 3y to both sides of the equation gives us:

-3x = 18 + 3y

Dividing both sides of the equation by -3, we get:

x = -6 - y

Now we substitute this expression for x into the first equation:

4x + 9y = -24

Substituting -6 - y for x, we have:

4(-6 - y) + 9y = -24

Simplifying the equation, we get:

-24 - 4y + 9y = -24

Combining like terms, we have:

5y = 0

Dividing both sides of the equation by 5, we find:

y = 0

Substituting this value back into the expression we found for x, we get:

x = -6 - 0

x = -6

Therefore, the solution to the system of equations is x = -3 and y = 4.

During the mating season you observe that individuals in the population will only mate with others of the same genotype (for example Dd individuals will only mate with Dd individuals). There are only two alleles at this locus ( D is dominant, d is recessive), and you have determined the frequency of the D allele =0.6 in this population. Selection acts against homozygous dominant individuals and their survivorship per generation is 80%. After one generation the frequency of DD individuals will decrease in the population.

According to the Hardy-Weinberg equilibrium equation p² + 2pq + q² = 1, the frequency of D (p) and d (q) alleles are:p + q = 1Thus, the frequency of q is 0.4. Here are the calculations for the Hardy-Weinberg equilibrium:p² + 2pq + q² = 1(0.6)² + 2(0.6)(0.4) + (0.4)² = 1After simplifying, it becomes:0.36 + 0.48 + 0.16 = 1This means that the population is in Hardy-Weinberg equilibrium.

The function y=0.4409 x²-5.1724 x+99.0321 models the emissions of carbon monoxide in the United States since 1987, where y represents the amount of carbon monoxide released in a year in millions of tons, and x=0 represents the year 1987.


b. How can you use the Quadratic Formula to estimate the year in which more than 100 million tons of carbon monoxide were released into the air?

Answers

The estimated year in which more than 100 million tons of carbon monoxide were released into the air is approximately 10.1311 years after 1987, which is around the year 1997.

To estimate the year in which more than 100 million tons of carbon monoxide were released into the air using the quadratic formula, we need to set up an equation.

Since y represents the amount of carbon monoxide released in millions of tons, we can set up the equation

[tex]0.4409x^2 - 5.1724x + 99.0321 = 100[/tex].

To solve this equation, we can rearrange it to match the quadratic formula:

[tex]0.4409x^2 - 5.1724x + 99.0321 - 100 = 0[/tex].

Now, we can use the quadratic formula, which states that for an equation of the form [tex]ax^2 + bx + c = 0[/tex], the solutions for x are given by [tex]x = (-b \pm \sqrt{(b^2 - 4ac)} / (2a)[/tex].

In our equation, a = 0.4409, b = -5.1724, and c = -0.9679.

Substituting these values into the quadratic formula, we get:
[tex]x = (-(-5.1724) \pm \sqrt{((-5.1724)^2 - 4(0.4409)(-0.9679))) / (2(0.4409))[/tex].

Simplifying this expression, we find two possible solutions for x:

[tex]0.4409x^2 - 5.1724x + 99.0321 = 100.[/tex]

x ≈ 10.1311 and x ≈ -0.0681.

Since x represents years, we can disregard the negative solution.

Therefore, the estimated year in which more than 100 million tons of carbon monoxide were released into the air is approximately 10.1311 years after 1987, which is around the year 1997.

This estimation is based on the quadratic model, so it's important to consider other factors that may affect carbon monoxide emissions in reality.

Additionally, please note that the quadratic model may not perfectly capture the actual emissions trend.

The solution to the given differential equation y" - cos x = 0 with y(0) = 2 and y'(0) = 1 is y = 3e^[-sin(x)].

The given differential equation is:

y"- cos x = 0

Given y(0) = 2 and y'(0) = 1. We need to find the integrating factor.

Let's find the complementary function first.

y" = cos x

=> y' = sin x

=> y = -cos x + c1

Since y(0) = 2, we get:-2 + c1 = 2 => c1 = 4

Let's find the particular integral. Using the integrating factor method, we get

y" - cos x = 0=> y" - cos x y = 0

The integrating factor is:

e^[int(-cos(x)dx)] = e^[sin(x)]

Multiplying the given differential equation with the integrating factor, we get:

[e^[sin(x)] y]" = 0

Integrating both sides, we get:

e^[sin(x)] y = c2

Since y'(0) = 1, we get:

c2 = e^[sin(0)]

y(0) + y'(0) = 2 + 1

= 3

Therefore, the solution to the given differential equation is: e^[sin(x)] y = 3

=> y = 3e^[-sin(x)]

Evaluate the following integral using power series. ∫ x2/6+x 5 dx

Answers

Answer:

Step-by-step explanation:

To evaluate the integral ∫(x^2/(6+x^5)) dx using power series, we can first express the integrand as a power series expansion.

We know that the geometric series formula is given by 1/(1-r) = 1 + r + r^2 + r^3 + ..., where |r| < 1.

Let's rewrite the integrand as x^2 * (1/(6+x^5)). We can rewrite the denominator as (1+x^5/6) and use the geometric series formula with r = -x^5/6:

1/(1+x^5/6) = 1 - x^5/6 + (x^5/6)^2 - (x^5/6)^3 + ...

Now, we can rewrite the integrand as:

x^2 * (1/(6+x^5)) = x^2 * (1 - x^5/6 + (x^5/6)^2 - (x^5/6)^3 + ...)

Now, we can integrate the power series term by term.

∫ (x^2 * (1/(6+x^5))) dx = ∫ (x^2 - (x^7/6) + (x^12/6^2) - (x^17/6^3) + ...) dx

Integrating each term of the power series individually, we get:

∫ x^2 dx - ∫ (x^7/6) dx + ∫ (x^12/6^2) dx - ∫ (x^17/6^3) dx + ...

= (x^3/3) - (x^8/48) + (x^13/(6^2 * 13)) - (x^18/(6^3 * 18)) + ...

The integral of the power series expansion is:

(x^3/3) - (x^8/48) + (x^13/(6^2 * 13)) - (x^18/(6^3 * 18)) + ... + C

where C is the constant of integration.

Answers

The solution to the Laplace equation is:  u(x, y) =Σ[Ansin(nπx)cos(nπy)] where An are coefficients determined by the initial condition f(x) for u(x, 0), and the summation is taken over positive integers n.

To solve the given Laplace equation, we can use the method of separation of variables. We assume a separable solution u(x, y) = X(x)Y(y) and substitute it into the equation, resulting in X''(x)Y(y) + X(x)Y''(y) = 0. Dividing by XY gives (1/X(x))X''(x) = -(1/Y(y))Y''(y) = constant.

This leads to two separate ordinary differential equations: X''(x) + λX(x) = 0 and Y''(y) + λY(y) = 0, where λ is the separation constant. The boundary conditions u(0, y) = 0 and u(1, y) = 0 imply X(0) = 0 and X(1) = 0. The solution to the X equation is given by X(x) = sin(nπx), where n is a positive integer.

Applying the boundary condition uy(x, 1) = 0, we obtain Y'(1) = 0. The solution to the Y equation is given by Y(y) = C cos(nπy), where C is a constant determined by the initial condition f(x) for u(x, 0).

The general solution is then expressed as u(x, y) = Σ[An sin(nπx)cos(nπy)], where An are coefficients determined by the initial condition f(x). The double series represents the superposition of the eigenfunctions sin(nπx)cos(nπy), and the specific solution depends on the choice of f(x).

To express the integral [tex]\(\iiint_E f(x, y, z) \, dV\)[/tex] as an iterated integral, we need to determine the limits of integration for each variable ((x), (y), and (z)).

The solid E is bounded by [tex]\(z = 0\), \(z = 4y\)[/tex], and [tex]\(x^2 = 49 - y\)[/tex].

Let's start with the first iterated integral with respect to \(x\):

1. [tex]\(\int_a^b \left( \int_c^d \left( \int_{g(x, y)}^{h(x, y)} f(x, y, z) \, dz \right) \, dy \right) \, dx\)[/tex]

To determine the limits of integration for (x), we need to find the range of (x) values that satisfy the condition \(x^2 = 49 - y\). Solving for \(x\), we have [tex]\(x = \pm \sqrt{49 - y}\)[/tex]. So, the limits of integration for \(x\) are \[tex]\sqrt{49 - y}\) to \(\sqrt{49 - y}\)[/tex].

For the limits of integration with respect to \(y\), we need to consider the bounds of \(y\) based on the given solid. We know that [tex]\(0 \leq z \leq 4y\)[/tex], so the lower bound for \(y\) is 0. For the upper bound, we need to determine where \(4y\) intersects with the parabolic surface

[tex](x^2 = 49 - y\)[/tex].

Substituting (4y) for (z) in the equation [tex]\(x^2 = 49 - y\)[/tex], we get

[tex](x^2 = 49 - 4y\)[/tex].

Solving for \(y\), we find [tex]\(y = \frac{49 - x^2}{4}\)[/tex].

Therefore, the upper bound for \(y\) is [tex]\(\frac{49 - x^2}{4}\)[/tex].

Finally, for the limits of integration with respect to \(z\), we know that (0) [tex]\leq z \leq 4y\)[/tex], so the lower bound for \(z\) is 0, and the upper bound is \(4y\).

Putting it all together, the first iterated integral is:

[tex]\(\int_a^b \left( \int_0^{\frac{49 - x^2}{4}} \left( \int_0^{4y} f(x, y, z) \, dz \right) \, dy \right) \, dx\)[/tex]
