a. The determinant of A is nonzero (-2 ≠ 0), the system of equations has a unique solution for all values of k.

b. For values of k less than 3, the system of equations has no solution.

c. There are no values of k for which the system of equations has infinite solutions.

To determine the values of k for which the given system of simultaneous equations has a unique solution, no solution, or infinite solutions, let's consider each case separately:

a. To find the values of k for which the equations have a unique solution, we need to check if the determinant of the coefficient matrix is nonzero. If the determinant is nonzero, it means that the equations can be uniquely solved.

To compute the determinant, we can write the coefficient matrix A as follows:
A = [[2, 4, -2], [2, 5, -(k+2)], [-1, k-5, 1]]

Expanding the determinant of A, we have:
det(A) = 2(5(1)-(k-5)(-2)) - 4(2(1)-(k+2)(-1)) - 2(2(k-5)-(-1)(2))

Simplifying this expression, we get:
det(A) = 10 + 2k - 10 - 4k - 4 + 2k + 4k - 10

Combining like terms, we have:
det(A) = -2

Since the determinant of A is nonzero (-2 ≠ 0), the system of equations has a unique solution for all values of k.

b. To find the values of k for which the equations have no solution, we can check if the determinant of the augmented matrix, [A|B], is nonzero, where B is the column vector on the right-hand side of the equations.

The augmented matrix is:
[A|B] = [[2, 4, -2, 4], [2, 5, -(k+2), 3], [-1, k-5, 1, 1]]

Expanding the determinant of [A|B], we have:
det([A|B]) = (2(5) - 4(2))(1) - (2(1) - (k+2)(-1))(4) + (-1(2) - (k-5)(-2))(3)

Simplifying this expression, we get:
det([A|B]) = 10 - 8 - 4k + 8 - 2k + 4 + 2 + 6k - 6

Combining like terms, we have:
det([A|B]) = -6k + 18

For the system to have no solution, the determinant of [A|B] must be nonzero. Therefore, for no solution, we must have:
-6k + 18 ≠ 0

Simplifying this inequality, we get:
-6k ≠ -18

Dividing both sides by -6 (and flipping the inequality), we have:
k < 3

Thus, for values of k less than 3, the system of equations has no solution.

c. To find the values of k for which the equations have infinite solutions, we can check if the determinant of A is zero and if the determinant of the augmented matrix, [A|B], is also zero.

From part (a), we know that the determinant of A is -2.

Therefore, to have infinite solutions, we must have:
-2 = 0

However, since -2 is not equal to zero, there are no values of k for which the system of equations has infinite solutions.

The Fourier series of f(t) = 31² is a₀ = 31² and all other coefficients are zero.

For (i)[tex]2x^5[/tex] - 5x³ + 7: even, (ii) x³ + x⁴: odd.

The Fourier series of f(x) = x is Σ(bₙsin(nπx/L)), where b₁ = 4L/π.

To find the Fourier series of the periodic function f(t) = 31² over the interval -1 ≤ t ≤ 1, we need to determine the coefficients of its Fourier series representation. Since f(t) is a constant function, all the coefficients except for the DC component will be zero. The DC component (a₀) is given by the average value of f(t) over one period, which is equal to the constant value of f(t). In this case, a₀ = 31².

For the functions (i)[tex]2x^5[/tex] - 5x³ + 7 and (ii) x³ + x⁴, we can determine their symmetry by examining their even and odd components. A function is even if f(-x) = f(x) and odd if f(-x) = -f(x).

(i) For[tex]2x^5[/tex] - 5x³ + 7, we observe that the even powers of x (x⁰, x², x⁴) are present, while the odd powers (x¹, x³, x⁵) are absent. Thus, the function is even.

(ii) For x³ + x⁴, both even and odd powers of x are present. By testing f(-x), we find that f(-x) = -x³ + x⁴ = -(x³ - x⁴) = -f(x). Hence, the function is odd.

For the function f(x) = x over the interval -L ≤ x ≤ L, we can determine its Fourier series by finding the coefficients of its sine terms. The Fourier series representation of f(x) is given by f(x) = a₀/2 + Σ(aₙcos(nπx/L) + bₙsin(nπx/L)), where a₀ = 0 and aₙ = 0 for all n > 0.

Since f(x) = x is an odd function, only the sine terms will be present in its Fourier series. The coefficient b₁ can be determined by integrating f(x) multiplied by sin(πx/L) over the interval -L to L and then dividing by L.

The Fourier series for f(x) = x over -L ≤ x ≤ L is given by f(x) = Σ(bₙsin(nπx/L)), where b₁ = 4L/π.

Solving given equations, we get line of intersection as  t = -11/4, t = -1, and t = 1/4, respectively. The point of intersection between the given lines is (-8, 2, 0). The point of intersection between the two planes is (2, 2, 86/65).

(10.2) To find the line of intersection between the lines, let's set up the equations for the two lines:

Line 1: r1 = <3, -1, 2> + t<1, 1, -1>

Line 2: r2 = <-8, 2, 0> + t<-3, 2, -7>

Now, we equate the two lines to find the point of intersection:

<3, -1, 2> + t<1, 1, -1> = <-8, 2, 0> + t<-3, 2, -7>

By comparing the corresponding components, we get:

3 + t = -8 - 3t   [x-component]

-1 + t = 2 + 2t   [y-component]

2 - t = 0 - 7t    [z-component]

Simplifying these equations, we find:

4t = -11   [from the x-component equation]

-3t = 3     [from the y-component equation]

8t = 2      [from the z-component equation]

Solving these equations, we get t = -11/4, t = -1, and t = 1/4, respectively.

To find the point of intersection, substitute the values of t back into any of the original equations. Taking the y-component equation as an example, we have:

-1 + t = 2 + 2t

Substituting t = -1, we find y = 2.

Therefore, the point of intersection between the given lines is (-8, 2, 0).

(10.3) Let's solve for the point of intersection between the two given planes:

Plane 1: -5x + y - 2z = 3

Plane 2: 2x - 3y + 5z = -7

To find the point of intersection, we need to solve this system of equations simultaneously. We can use the method of substitution or elimination to find the solution.

Let's use the method of elimination:

Multiply the first equation by 2 and the second equation by -5 to eliminate the x term:

-10x + 2y - 4z = 6

-10x + 15y - 25z = 35

Now, subtract the second equation from the first equation:

0x - 13y + 21z = -29

To simplify the equation, divide through by -13:

y - (21/13)z = 29/13

Now, let's solve for y in terms of z:

y = (21/13)z + 29/13

We still need another equation to find the values of z and y. Let's use the y-component equation from the second plane:

y - 3 = -5s

Substituting y = (21/13)z + 29/13, we have:

(21/13)z + 29/13 - 3 = -5s

Simplifying, we get:

(21/13)z - (34/13) = -5s

Now, we can equate the z-components of the two equations:

(21/13)z - (34/13) = 2z + 4

Simplifying further, we have:

(21/13)z - 2z = (34/13) + 4

(5/13)z = (34/13) + 4

(5/13)z = (34 + 52)/13

(5/13)z =

86/13

Solving for z, we find z = 86/65.

Substituting this value back into the y-component equation, we can find the value of y:

y = (21/13)(86/65) + 29/13

Simplifying, we have: y = 2

Therefore, the point of intersection between the two planes is (2, 2, 86/65).

γ > 1/2, (1-2γ)/γ < 0, which means the second derivative is negative. Therefore, the long-run cost function is strictly concave in q.

Part a: To determine whether the production function exhibits increasing returns to scale or decreasing returns to scale, we need to examine how changes in inputs affect output.

In general, a production function exhibits increasing returns to scale if doubling the inputs more than doubles the output, and it exhibits decreasing returns to scale if doubling the inputs less than doubles the output.

Given the production function q = (KL)^γ, where γ > 1/2, let's consider the effect of scaling the inputs by a factor of λ, where λ > 1.

When we scale the inputs by a factor of λ, we have K' = λK and L' = λL. Substituting these values into the production function, we get:

q' = (K'L')^γ

  = (λK)(λL)^γ

  = λ^γ * (KL)^γ

  = λ^γ * q

Since λ^γ > 1 (because γ > 1/2 and λ > 1), we can conclude that doubling the inputs (λ = 2) results in more than doubling the output. Therefore, the production function exhibits increasing returns to scale.

Part b: To derive the long-run cost function C(q, γ), we need to determine the cost of producing a given quantity q, taking into account the production function and input prices.

The cost function can be expressed as C(q) = wK + rL, where w is the wage rate and r is the rental rate.

In this case, we are given that (w, r) = (1, 1), so the cost function simplifies to C(q) = K + L.

Using the production function q = (KL)^γ, we can express L in terms of K and q as follows:

q = (KL)^γ

q^(1/γ) = KL

L = (q^(1/γ))/K

Substituting this expression for L into the cost function, we have:

C(q) = K + (q^(1/γ))/K

Therefore, the long-run cost function is C(q, γ) = K + (q^(1/γ))/K.

Part c: To determine whether the long-run cost function is linear, strictly convex, or strictly concave in q, we need to examine the second derivative of the cost function with respect to q.

Taking the second derivative of C(q, γ) with respect to q:

d^2C(q, γ)/[tex]dq^2 = d^2/dq^2[/tex][K + (q^(1/γ))/K]

              = d/dq [(1/γ)(q^((1-γ)/γ))/K]

To join the points (2, 16) and (8, 4), we can use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept.

First, let's calculate the slope (m) using the formula:

m = (y2 - y1) / (x2 - x1)

Substituting the coordinates of the two points:

m = (4 - 16) / (8 - 2)

m = -12 / 6

m = -2

Now that we have the slope, we can choose either of the two points and substitute its coordinates into the slope-intercept form to find the y-intercept (b).

Let's choose the point (2, 16):

16 = -2(2) + b

16 = -4 + b

b = 20

Now we have the slope (m = -2) and the y-intercept (b = 20), we can write the equation of the line:

y = -2x + 20

This equation represents the line passing through the points (2, 16) and (8, 4).

The required coefficient of x^34 is C(20, 17). To determine the coefficient of x^34 in the full expansion of (x² - 2/x)^20, we can use the binomial theorem.

The binomial theorem states that for any positive integer n:
(x + y)^n = C(n, 0) * x^n * y^0 + C(n, 1) * x^(n-1) * y^1 + C(n, 2) * x^(n-2) * y^2 + ... + C(n, n) * x^0 * y^n
Where C(n, k) represents the binomial coefficient, which is calculated using the formula:
C(n, k) = n! / (k! * (n-k)!)
In this case, we have (x² - 2/x)^20, so x is our x term and -2/x is our y term.
To find the coefficient of x^34, we need to determine the value of k such that x^(n-k) = x^34. Since the exponent on x is 2 in the expression, we can rewrite x^(n-k) as x^(2(n-k)).
So, we need to find the value of k such that 2(n-k) = 34. Solving for k, we get k = n - 17.
Therefore, the coefficient of x^34 is C(20, 17).
Now, let's determine the coefficient of x^-17 in the same expansion. Since we have a negative exponent, we can rewrite x^-17 as 1/x^17. Using the binomial theorem, we need to determine the value of k such that x^(n-k) = 1/x^17.
So, we need to find the value of k such that 2(n-k) = -17. Solving for k, we get k = n + 17/2.
Since k must be an integer, n must be odd to have a non-zero coefficient for x^-17. In this case, n is 20, which is even. Therefore, the coefficient of x^-17 is 0.
To summarize:
- The coefficient of x^34 in the full expansion of (x² - 2/x)^20 is C(20, 17).
- The coefficient of x^-17 in the same expansion is 0.

To calculate the future value of a series of deposits, we can use the formula for the future value of an ordinary annuity:

FV = P * [(1 + r)^n - 1] / r

Where:

FV is the future value

P is the periodic payment

r is the interest rate per period

n is the number of periods

In this case, the periodic payment is $1,000, the interest rate is 7% (or 0.07), and the number of periods is 20.

Plugging these values into the formula, we get:

FV = 1000 * [(1 + 0.07)^20 - 1] / 0.07

  = 1000 * [1.07^20 - 1] / 0.07

  ≈ 1000 * [2.6532976 - 1] / 0.07

The given sequence an = 1 (n+4)! (4n+ 1)! is decreasing and bounded. Option 2 is the correct answer.

To determine whether the sequence

[tex]an = 1/(n+4)!(4n+1)![/tex]

is increasing, decreasing, or neither, we can look at the ratio of consecutive terms:

Thus,

[tex]a(n+1)/an = [1/(n+5)!(4n+5)!] / [1/(n+4)!(4n+1)!] \\

= [(n+4)!(4n+1)!] / [(n+5)!(4n+5)!] \\

= (4n+1)/(4n+5)[/tex]

The ratio of consecutive terms is a decreasing function of n, since (4n+1)/(4n+5) < 1 for all n.

Hence, the sequence is decreasing.

To determine whether the sequence is bounded, we need to find an upper bound and a lower bound for the sequence.

Note that all terms of the sequence are positive, since the factorials and the denominator of each term are positive.

We can use the inequality

[tex](4n+1)! < (4n+1)^{4n+1/2}[/tex]

to obtain an upper bound for the sequence:

[tex]an < 1/(n+4)!(4n+1)! \\

< 1/[(n+4)/(4n+1)^{4n+1/2}] \\

To solve the given questions, let's analyze each part one by one:

a) The y-intercept is (0, 0).

Find the x- and y-intercepts of y = f(x):

The x-intercepts are the points where the graph of the function intersects the x-axis, meaning the y-coordinate is zero. To find the x-intercepts, set y = 0 and solve for x:

0 = 4x²(x² - 9)

This equation can be factored as:

0 = 4x²(x + 3)(x - 3)

From this factorization, we can see that there are three possible solutions for x:

x = 0 (gives the x-intercept at the origin, (0, 0))

x = -3 (gives an x-intercept at (-3, 0))

x = 3 (gives an x-intercept at (3, 0))

The y-intercept is the point where the graph intersects the y-axis, meaning the x-coordinate is zero. To find the y-intercept, substitute x = 0 into the equation:

y = 4(0)²(0² - 9)

y = 4(0)(-9)

y = 0

Therefore, the y-intercept is (0, 0).

b) Find the equation of all vertical asymptotes (if they exist):

Vertical asymptotes occur when the function approaches infinity or negative infinity as x approaches a particular value. To find vertical asymptotes, we need to check where the function is undefined.

In this case, the function is undefined when the denominator of a fraction is equal to zero. The denominator in our case is (x² - 9), so we set it equal to zero:

x² - 9 = 0

This equation can be factored as the difference of squares:

(x - 3)(x + 3) = 0

From this factorization, we find that x = 3 and x = -3 are the values that make the denominator zero. These values represent vertical asymptotes.

Therefore, the equations of the vertical asymptotes are x = 3 and x = -3.

c) Find the equation of all horizontal asymptotes (if they exist):

To determine horizontal asymptotes, we need to analyze the behavior of the function as x approaches positive or negative infinity.

Given that the highest power of x in the numerator and denominator is the same (both are x²), we can compare their coefficients to find horizontal asymptotes. In this case, the coefficient of x² in the numerator is 4, and the coefficient of x² in the denominator is 1.

Since the coefficient of the highest power of x is greater in the numerator, there are no horizontal asymptotes in this case.

To maximize the sugar you can gain from street vendors and satisfy your sweet tooth, you can use the following expression:

m[i] = max(m[i-1] + s[i], s[i])

Here, m[i] represents the maximum sugar you can consume so far on the i-th vendor, and s[i] denotes the sugar content of the i-th vendor's offering.

The expression utilizes dynamic programming to calculate the maximum sugar consumption at each step. The variable m[i] stores the maximum sugar you can have up to the i-th vendor.

The expression considers two options: either including the sugar content of the current vendor (s[i]) or starting a new consumption from the current vendor.

To calculate m[i], we compare the sum of the maximum sugar consumption until the previous vendor (m[i-1]) and the sugar content of the current vendor (s[i]) with just the sugar content of the current vendor (s[i]). Taking the maximum of these two options ensures that m[i] stores the highest sugar consumption achieved so far.

By iterating through all the vendors and applying this expression, you can determine the maximum sugar you can gain from the street vendors and satisfy your sweet tooth.

To find the median in a continuous series, the lower limit and frequency of the median class are important. The correct answer is option (b). For the given continuous data distribution, the value of Q3 is 30.

To find the median in a continuous series, the lower limit and frequency of the median class are important. Therefore, the correct answer is option (b).

To find Q3 in a continuous data distribution, we need to first find the median (Q2). The total frequency is 3+5+7+1 = 16, which is even. Therefore, the median is the average of the 8th and 9th values.

The 8th value is in the class 30-40, which has a cumulative frequency of 3+5 = 8. The lower limit of this class is 30. The class width is 10.

The 9th value is also in the class 30-40, so the median is in this class. The particular frequency of this class is 7. Therefore, the median is:

Q2 = lower limit of median class + [(n/2 - cumulative frequency of the class before median class) / particular frequency of median class] * class width

Q2 = 30 + [(8 - 8) / 7] * 10 = 30

To find Q3, we need to find the median of the upper half of the data. The upper half of the data consists of the classes 30-40 and 40-50. The total frequency of these classes is 7+1 = 8, which is even. Therefore, the median of the upper half is the average of the 4th and 5th values.

The 4th value is in the class 40-50, which has a cumulative frequency of 8. The lower limit of this class is 40. The class width is 10.

The 5th value is also in the class 40-50, so the median of the upper half is in this class. The particular frequency of this class is 1. Therefore, the median of the upper half is:

Q3 = lower limit of median class + [(n/2 - cumulative frequency of the class before median class) / particular frequency of median class] * class width

Q3 = 40 + [(4 - 8) / 1] * 10 = 0

Therefore, the correct answer is option (b): 30.

The absolute maximum and absolute minimum of the function () = 12 9 − 32 − 3 over the interval [0, 3], we need to evaluate the function at critical points and endpoints. The absolute maximum is -3 at x = 0, and the absolute minimum is approximately -3.73 at x ≈ 0.183.

Step 1: Find the critical points by setting the derivative equal to zero and solving for x.

() = 12 9 − 32 − 3

() = 27 − 96x² − 3x²

Setting the derivative equal to zero, we have:

27 − 96x² − 3x² = 0

-99x² + 27 = 0

x² = 27/99

x = ±√(27/99)

x ≈ ±0.183

Step 2: Evaluate the function at the critical points and endpoints.

() = 12 9 − 32 − 3

() = 12(0)² − 9(0) − 32(0) − 3 = -3 (endpoint)

() ≈ 12(0.183)² − 9(0.183) − 32(0.183) − 3 ≈ -3.73 (critical point)

Step 3: Compare the values to determine the absolute maximum and minimum.

The absolute maximum occurs at x = 0 with a value of -3.

The absolute minimum occurs at x ≈ 0.183 with a value of approximately -3.73.

Therefore, the absolute maximum is -3 at x = 0, and the absolute minimum is approximately -3.73 at x ≈ 0.183.

The standard matrix of the linear transformation T: R² -> R⁴ is A = [5 -9; 1 3; 5 0; 1 0].

To find the standard matrix of the linear transformation T, we need to determine the images of the standard basis vectors e₁ = (1, 0) and e₂ = (0, 1) under T.

Given that T(e₁) = (5, 1, 5, 1) and T(e₂) = (-9, 3, 0, 0), we can represent these image vectors as column vectors.

The standard matrix A of T is formed by arranging these column vectors side by side. Therefore, A = [T(e₁) T(e₂)].

We have T(e₁) = (5, 1, 5, 1) and T(e₂) = (-9, 3, 0, 0), so the standard matrix A becomes:

A = [5 -9; 1 3; 5 0; 1 0].

This matrix A represents the linear transformation T from R² to R⁴.

The function that models the inverse variation between variables a and b is given by b = k/a, where k is the constant of variation.

In inverse variation, two variables are inversely proportional to each other. This can be represented by the equation b = k/a, where b and a are the variables and k is the constant of variation.

To Find the specific function that models the inverse variation between a and b, we can use the given information. When a = 9, b = 5/3.

Plugging these values into the inverse variation equation, we have:

5/3 = k/9

To solve for k, we can cross-multiply:

5 * 9 = 3 * k

45 = 3k

Dividing both sides by 3:

k = 45/3

Simplifying:

k = 15

Therefore, the function that models the inverse variation between a and b is:

b = 15/a

This equation demonstrates that as the value of a increases, the value of b decreases, and vice versa. The constant of variation, k, determines the specific relationship between the two variables.

Answer:

218 cm²

Step-by-step explanation:

The lateral surface area (LSA) is the area of the sides excluding the top and botton part

LSA formula: 2h(l+b)

For the larger(green) cuboid, h = 4, l = 10, b =5

For the smaller(pink) cuboid, h = 6, l = 2, b =2

Total area = LSA(green) + top part of green + LSA(pink) + top of pink

LSA of green :

2h(l+b) = 2(4)(10+5)

= 8*15

= 120  -----eq(1)

Top part of green:

The area of green cuboid's top- area of pink cuboid's base

= (10*5) - (2*2)

= 50 - 4

= 46  -----eq(2)

LSA of pink:

2h(l+b) = 2(6)(2+2)

= 12*4

= 48  -----eq(3)

Top part of pink:

2*2 = 4  -----eq(3)

Total area:

eq(1) + eq(2) + eq(3) + eq(4)

= 120 + 45 + 48 + 4

The general solution to the nonhomogeneous ODE is y(x) = y_c(x) + y_p(x), where y_c(x) is the complementary solution from step 1 and y_p(x) is the particular solution obtained in step 2.

Step 1: Find the Complementary Solution

First, we find the complementary solution to the homogeneous equation y'' + 25y = 0. The characteristic equation is[tex]r^2 + 25 = 0,[/tex] which yields the solutions r = ±5i. Therefore, the complementary solution is y_c(x) = c1*cos(5x) + c2*sin(5x), where c1 and c2 are arbitrary constants.

Step 2: Find Particular Solutions

We assume the particular solution to the nonhomogeneous equation in the form of y_p(x) = u1(x)*cos(5x) + u2(x)*sin(5x), where u1(x) and u2(x) are functions to be determined.

Step 3: Determine u1'(x) and u2'(x)

Differentiate y_p(x) to find u1'(x) and u2'(x):

u1'(x) = -A(x)*cos(5x),

u2'(x) = -A(x)*sin(5x),

where[tex]A(x) = ∫[cos(5x)csc^2(5x)]dx.[/tex]

Step 4: Substitute y_p(x), y_p'(x), and y_p''(x) into the ODE

Substitute y_p(x), y_p'(x), and y_p''(x) into the original nonhomogeneous ODE and simplify to obtain:

-u1'(x)*cos(5x) - u2'(x)*sin(5x) + 25[u1(x)*cos(5x) + u2(x)*sin(5x)] = cos(5x)csc^2(5x).

Step 5: Solve for u1'(x) and u2'(x)

Equating coefficients of cos(5x) and sin(5x) on both sides of the equation, we can solve for u1'(x) and u2'(x). This involves integrating A(x) and performing algebraic manipulations.

Step 6: Integrate u1'(x) and u2'(x) to find u1(x) and u2(x)

Once u1'(x) and u2'(x) are determined, integrate them with respect to x to obtain u1(x) and u2(x), respectively.

Step 7: Determine the General Solution

The general solution to the nonhomogeneous ODE is y(x) = y_c(x) + y_p(x), where y_c(x) is the complementary solution from step 1 and y_p(x) is the particular solution obtained in step 2.

The instantaneous growth rate of an investment represents the rate at which its value is increasing at any given moment. In this case, the interest rate is 5%, which means that the investment grows by 5% each year.

In the first step, to calculate the instantaneous growth rate, we simply take the given interest rate, which is 5%.

In the second step, to find the amount of the investment after 5 years when compounded continuously, we use the continuous compounding formula: A = P * e^(rt), where A is the final amount, P is the principal (initial investment), e is the base of the natural logarithm, r is the interest rate, and t is the time in years. Plugging in the values, we have A = 12000 * e^(0.05 * 5) ≈ $16,283.19.

In the third step, to find the amount of the investment after 5 years when compounded quarterly, we use the compound interest formula: A = P * (1 + r/n)^(nt), where n is the number of compounding periods per year. In this case, n is 4 since the investment is compounded quarterly. Plugging in the values, we have A = 12000 * (1 + 0.05/4)^(4 * 5) ≈ $16,209.62.

The approximate price of a 12oz box of Kellogg's Corn Flakes in 2008, with an initial price of $0.89 in 1984 and two subsequent increases of 235% and 105%, would be approximately $6.12

To calculate the price of a 12oz box of Kellogg's Corn Flakes in 2008, considering an increase of 235% and an additional increase of 105% from the initial price in 1984, we can follow these steps:

Step 1: Calculate the first increase of 235%:

First, we need to find the price after the first increase. To do this, we multiply the initial price in 1984 by 235% and add it to the initial price:

First increase = $0.89 * (235/100) = $2.09315

New price after the first increase = $0.89 + $2.09315 = $2.98315 (rounded to 5 decimal places)

Step 2: Calculate the additional increase of 105%:

Next, we need to calculate the second increase based on the price after the first increase. To do this, we multiply the price after the first increase by 105% and add it to the price:

Second increase = $2.98315 * (105/100) = $3.13231

New price after the additional increase = $2.98315 + $3.13231 = $6.11546 (rounded to 5 decimal places)

Therefore, the approximate price of a 12oz box of Kellogg's Corn Flakes in 2008, with an initial price of $0.89 in 1984 and two subsequent increases of 235% and 105%, would be approximately $6.12.

Answer: A. 6n-11

Step-by-step explanation:

First, ignore the parenthesis because it is addition and subtraction so they are commutative. 10n-4n = 6n and -8-3 is the same as -8+-3 which is -11. Combining the answer gives 6n-11.

(a) The general solution to the ODE is S * y = -x + C.

(b) The particular solution is y = -(1/S) * x + (1 + 1/S).

(c) The solution exists and is unique for all x as long as S is a non-zero constant.

(a) To find the general solution to the given initial value problem (IVP), we need to solve the ordinary differential equation (ODE) and express the solution in implicit form.

The ODE is:

S * 3x^2 * dy/dx = -1

To solve the ODE, we can separate the variables and integrate:

S * 3x^2 * dy = -dx

Integrating both sides:

∫ (S * 3x^2 * dy) = ∫ (-dx)

S * ∫ 3x^2 * dy = ∫ -dx

S * y = -x + C

Here, C is the constant of integration.

Therefore, the general solution to the ODE is:

S * y = -x + C

(b) Now, let's use the initial data in the IVP to find a particular solution.

The initial data is y(1) = 1.

Substituting x = 1 and y = 1 into the general solution:

S * 1 = -1 + C

Simplifying:

S = -1 + C

Solving for C, we have:

C = S + 1

Substituting the value of C back into the general solution, we get the particular solution:

S * y = -x + (S + 1)

Simplifying further:

y = -(1/S) * x + (1 + 1/S)

Therefore, the particular solution, written in explicit form, is:

y = -(1/S) * x + (1 + 1/S)

(c) The largest open interval containing the initial data (where a solution exists and is unique) depends on the specific value of S. Without knowing the value of S, we cannot determine the exact interval. However, as long as S is a non-zero constant, the solution is valid for all x.
