The calculated diagonal length of the square (80.34 feet) to the distance between the vertices in the blueprint (12.73 units), it is evident that the blueprint does not accurately represent the length of the diagonal of square C.

To determine whether the blueprint accurately represents the length of the diagonal of square C, we can calculate the distance between the given vertices (3, 5) and (12, 14) and compare it to the length of the diagonal of the square.

Let's calculate the distance between the two vertices using the distance formula:

Distance = √[tex]((x2 - x1)^2 + (y2 - y1)^2).[/tex]

Plugging in the coordinates (x1, y1) = (3, 5) and (x2, y2) = (12, 14), we have:

Distance = [tex]√((12 - 3)^2 + (14 - 5)^2)[/tex]

        [tex]= √(9^2 + 9^2)[/tex]

        =[tex]√(81 + 81)[/tex]

        = √162

        ≈ 12.73.

Now, let's compare this distance to the length of the diagonal of square C. Since we know that 1 square unit in the blueprint corresponds to 25 square feet, we need to convert the square footage to square units to make the comparison.

Assuming the blueprint represents square C accurately, the area of the square in square feet would be[tex](12.73)^2 * 25 = 3,224.22[/tex] square feet.

Now, let's find the side length of the square by taking the square root of its area:

Side length = √3,224.22

           ≈ 56.79 feet.

Finally, let's calculate the length of the diagonal of the square using the side length:

Diagonal = Side length * √2

        ≈ 56.79 * 1.414

        ≈ 80.34 feet.

Comparing the calculated diagonal length of the square (80.34 feet) to the distance between the vertices in the blueprint (12.73 units), it is evident that the blueprint does not accurately represent the length of the diagonal of square C. The actual diagonal length is significantly larger than what is depicted in the blueprint.

The block time in the Bitcoin blockchain is designed to be 10 minutes for security, scalability, etc. If the block time is significantly reduced to around 10 seconds issues like security risks may occur.

1. a) Security: A longer block time provides more time for the network to reach a consensus on the validity of transactions. Each block contains a set of transactions that need to be verified and added to the blockchain. With a longer block time, there is more time for nodes in the network to validate transactions, reducing the chances of malicious actors manipulating the network.

b) Scalability: A longer block time allows more transactions to be included in each block. This helps in accommodating the increasing number of transactions over time without overwhelming the network. If the block time is too short, there would be a limit on the number of transactions that can be processed within a block, leading to congestion and higher transaction fees.

c) Blockchain size: Longer block times result in slower growth of the blockchain size. Each block added to the blockchain increases the storage requirements for running a full node. By having a longer block time, the growth rate of the blockchain is reduced, making it more manageable for participants to store and maintain a copy of the entire blockchain.

If the block time is significantly reduced to around 10 seconds, several issues may arise:

a) Security risks: A shorter block time reduces the time available for consensus, making the network more susceptible to double-spending attacks and other malicious activities. It becomes easier for an attacker to create competing blocks and disrupt the consensus process.

b) Forking and blockchain reorganization: With a shorter block time, there is a higher chance of multiple miners solving blocks simultaneously, leading to frequent forks and blockchain reorganizations. This can result in a less stable and reliable blockchain, making it harder for participants to trust the confirmed transactions.

c) Network congestion: A shorter block time increases the frequency of block creation, which may lead to network congestion and longer confirmation times for transactions. It becomes more challenging to prioritize and include a significant number of transactions within each block, potentially causing delays and increased transaction fees.

2. To reduce storage requirements without compromising accuracy performance in the Bitcoin blockchain, a solution called "pruning" is employed.

Pruning involves discarding older blockchain data while still maintaining the integrity and validity of the blockchain. Instead of storing the entire transaction history from the genesis block, a pruned node only keeps a subset of the blockchain data necessary to validate new transactions.

It helps reduce the storage burden for nodes while ensuring that they can still contribute to the security and validation of the blockchain. It enables nodes with limited storage capacity to participate in the network without sacrificing the accuracy and reliability of the Bitcoin blockchain.

The average slope of the function f(x) = -3x^2 + 5 from x = w to x = w + h is -6w - 3h. This represents the change in the function values divided by the change in x-values and provides a measure of the average rate of change of the function over the interval.

To find the average slope of the function f(x) = -3x^2 + 5 from x = w to x = w + h, we calculate the difference in function values at the two endpoints divided by the difference in x-values. Simplifying the expression involves evaluating f(w + h) and f(w), and then simplifying the resulting fraction.

The average slope of a function f(x) from x = w to x = w + h is given by the formula (f(w + h) - f(w))/h. In this case, the function is f(x) = -3x^2 + 5.

First, we evaluate f(w + h) and f(w) by substituting the corresponding values of x into the function:

f(w + h) = -3(w + h)^2 + 5

f(w) = -3w^2 + 5

Next, we substitute these values into the average slope formula and simplify:

Average slope = (f(w + h) - f(w))/h = (-3(w + h)^2 + 5 - (-3w^2 + 5))/h

Expanding and simplifying the expression inside the numerator, we have:

Average slope = ((-3w^2 - 6wh - 3h^2 + 5) + 3w^2 - 5)/h

The terms -3w^2 and 5 cancel out, leaving:

Average slope = (-6wh - 3h^2)/h

Using the product rule, the derivative of g(x) is given by:

g'(x) = [(x³ - 1)²]' (3x + 5) + (x³ - 1)² (3x + 5)'

Now, let's differentiate each term separately. First, we find the derivative of (x³ - 1)² using the chain rule. Let u = x³ - 1:

[(x³ - 1)²]' = 2(u)² * u'

= 2(x³ - 1)² * (3x²)

Next, we find the derivative of (3x + 5):

(3x + 5)' = 3

Substituting these derivatives back into the original expression, we have:

g'(x) = 2(x³ - 1)² * (3x²) * (3x + 5) + (x³ - 1)² * 3

Now, we can simplify the expression by expanding and combining like terms:

g'(x) = 6(x³ - 1)²(x²)(3x + 5) + 3(x³ - 1)²

Simplifying further, we have:

g'(x) = 6x²(x³ - 1)²(3x + 5) + 3(x³ - 1)²

When x = 2, we have y = 4√2.

Next, we can calculate the value of y when x = 2 + 0.3 by substituting it into the equation:

y = 4√(2 + 0.3).

By evaluating these expressions, we can find the change in y, Δy, which is given by:

Δy = y(x + Δx) - y(x) = 4√(2 + 0.3) - 4√2.

In this case, the derivative of y = 4√x with respect to x is given by:

dy/dx = (4/2√x) = 2/√x.

Substituting x = 2 and dx = 0.3, we can find the value of the differential dy:

dy = (2/√2) * 0.3 = (2/√2) * (3/10) = 3/√2 * 3/10 = 9/(√2 * 10).

f[g(x)]= 8(6x - 1) + 3 = 48x - 5

g[f(x)]= 6(8x + 3) - 1 = 48x + 17

To find f[g(x)], we substitute g(x) = 6x - 1 into the function f(x) = 8x + 3. We replace every occurrence of x in f(x) with g(x):

f[g(x)] = f[6x - 1] = 8(6x - 1) + 3 = 48x - 5

Similarly, to find g[f(x)], we substitute f(x) = 8x + 3 into the function g(x) = 6x - 1:

g[f(x)] = g[8x + 3] = 6(8x + 3) - 1 = 48x + 17

In both cases, we simplified the expressions to obtain the final results. These expressions represent the composition of the functions f(x) and g(x), where the output of one function is used as the input for the other.

It's important to note that function composition is not commutative, meaning that f[g(x)] and g[f(x)] can yield different results.

Differential equations involve the study of mathematical equations that relate an unknown function to its derivatives or differentials.

Zero-input response (yzi(t)) refers to the response of the system when there is no input (x(t) = 0). To find the zero-input response of the given system, we need to solve the homogeneous equation:

d²y(t)/dt² + 4(dy(t)/dt) + 3y(t) = 0

Using the characteristic equation approach, let's assume the solution to the homogeneous equation is of the form y(t) = e^(λt). Substituting this into the equation, we get:

λ²e^(λt) + 4λe^(λt) + 3e^(λt) = 0

Dividing the equation by e^(λt) gives:

λ² + 4λ + 3 = 0

Factoring the quadratic equation, we have:

(λ + 3)(λ + 1) = 0

This gives two distinct values for λ: λ = -3 and λ = -1.

Therefore, the general solution for the homogeneous equation is:

y(t) = c₁e^(-3t) + c₂e^(-t)

Using the initial conditions y(0) = -3 and y'(0) = 2, we can find the particular solution. Differentiating y(t) with respect to t and applying the initial conditions, we obtain:

y'(t) = -3c₁e^(-3t) - c₂e^(-t)

Applying the initial conditions y(0) = -3 and y'(0) = 2, we get:

c₁ + c₂ = -3 (equation 1)

-3c₁ - c₂ = 2 (equation 2)

Solving equations 1 and 2 simultaneously, we find c₁ = -2 and c₂ = -1.

Therefore, the zero-input response of the system is given by:

yzi(t) = -2e^(-3t) - e^(-t)

To find the zero-state response (yzs(t)) of the system to the unit step input (x(t) = u(t)), we need to solve the differential equation:

d²y(t)/dt² + 4(dy(t)/dt) + 3y(t) = u(t) - 2u(t)

Taking the Laplace transform of both sides of the equation, we have:

s²Y(s) - sy(0) - y'(0) + 4sY(s) - 4y(0) + 3Y(s) = 1/s - 2/s

Applying the initial conditions y(0) = -3 and y'(0) = 2, and rearranging the equation, we get:

s²Y(s) + 4sY(s) + 3Y(s) - s(-3) - 2 + 4(-3) = 1/s - 2/s

Simplifying further, we have:

Y(s) = (s + 7)/(s² + 4s + 3) + 1/(s(s - 2))

Using partial fraction decomposition, we can express Y(s) as:

Y(s) = A/(s + 1) + B/(s + 3) + C/s + D/(s - 2)

Multiplying through by the denominator, we get:

  - Constraint 2: 4C + D ≤ 24 (as there are 24 hours available in a day).

3. Machine C constraint: The available hours for machine C can be represented as 2C + D (as 2 hours are required for chocolate and 1 hour for candy for each production). Since machine C is rented and costs 10 pounds per hour, this cost needs to be considered.

  - Constraint 3: 2C + D ≤ 24 (as there are 24 hours available in a day).

  - Constraint 4: 10(2C + D) ≤ Budget (to ensure the cost of renting machine C is within the budget).

4. Non-negativity constraints: The number of times the factory produces chocolate and candy cannot be negative.

  - Constraint 5: C ≥ 0

  - Constraint 6: D ≥ 0

In summary, the LP model can be written as follows:

Maximize: Profit = 600C + 400D

2. 4C + D ≤ 24

3. 2C + D ≤ 24

4. 10(2C + D) ≤ Budget

5. C ≥ 0

6. D ≥ 0

To find F(s), the Laplace transform of f(t), we can use the properties of the Laplace transform. Here, f(t) = ae^bt cos(mt) u(t), where a = 2, b = 5, and m = 10.

Using the properties of the Laplace transform, we have:

F(s) = L{f(t)} = L{ae^bt cos(mt) u(t)}

To find F(s), we can apply the Laplace transform to each term individually. The Laplace transform of e^bt is given by:

The Laplace transform of cos(mt) is given by:

L{cos(mt)} = s / (s^2 + m^2)

Finally, the Laplace transform of u(t) is:

L{u(t)} = 1 / s

Now, we can substitute these values into the expression for F(s):

The value of Δy/Δx for the interval [3,8] in the equation y = 5x - 6 is equal to 5.

Δy/Δx represents the average rate of change of y with respect to x over a given interval. In this case, we are interested in calculating the average rate of change for the interval [3,8] in the equation y = 5x - 6. To find this value, we need to compute the difference in y-values (Δy) divided by the difference in x-values (Δx) over the interval.  

Substituting the given x-values into the equation, we find that y(3) = 5(3) - 6 = 9 and y(8) = 5(8) - 6 = 34. The change in y (Δy) over the interval is 34 - 9 = 25, and the change in x (Δx) is 8 - 3 = 5. Therefore, Δy/Δx = 25/5 = 5.

This means that, on average, for every increase of 1 unit in x within the interval [3,8], y increases by 5 units. The ratio Δy/Δx provides a measure of the slope of the line represented by the equation y = 5x - 6, indicating the rate at which y changes in relation to x.

a) The growth rate, k, to six decimal places is approximately 0.085585. The exponential function F(t) for total receipts in trillions of dollars is F(t) = 2.20 * e^(0.085585t).

a) the growth rate, k, we can use the formula for exponential growth: F(t) = F0 * e^(kt), where F(t) is the value at time t, F0 is the initial value at t=0, and k is the growth rate.

Using the given information, we have F(0) = 2.20 trillion and F(2) = 2.67 trillion. Plugging these values into the exponential growth formula, we get 2.67 = 2.20 * e^(2k).

Simplifying the equation, we have e^(2k) = 2.67 / 2.20. Taking the natural logarithm of both sides, we get 2k = ln(2.67 / 2.20).

Solving for k, we divide both sides by 2 and evaluate the expression to six decimal places, giving us k ≈ 0.085585.

b)  estimate total federal receipts in 2015, we substitute t = 4 (2015 - 2011) into the exponential function. F(4) = 2.20 * e^(0.085585 * 4), which can be calculated to obtain the estimated value.

c)  when total federal receipts will be $13 trillion, we set F(t) = 13 and solve for t in the exponential function. 13 = 2.20 * e^(0.085585t). Taking the natural logarithm of both sides and solving for t will give us the desired time.

1. The composite transformation can be implemented with a single [tex]\(3 \times 3\)[/tex] matrix. 2. The equation formula for the composite transformation is [tex]\([x', y', 1] = M \cdot [x, y, 1]\)[/tex].3. Applying the composite transformation, the transformed points:  (0.707,−3.293)(0.707,−3.293), (4.071,−5.071)(4.071,−5.071), (2.536,−6.536)(2.536,−6.536), (1.707,−5.293)(1.707,−5.293), (−1.121,−5.535)(−1.121,−5.535), and (−2.121,−4.535)(−2.121,−4.535).

To implement a composite transformation consisting of a translation to the left/down followed by a rotation, let's proceed with the given details:

Step 1: Finding the composite transformation matrix

Translation matrix:

The translation matrix for a 2D transformation is given by:

T = [[1, 0, t_x],

    [0, 1, t_y],

    [0, 0, 1]]

where `t_x` represents the translation in the x-axis (to the left) and `t_y` represents the translation in the y-axis (down).

Rotation matrix:

The rotation matrix for a 2D transformation is given by:

R = [[cos(theta), -sin(theta), 0],

    [sin(theta), cos(theta), 0],

    [0, 0, 1]]

where `theta` represents the angle of rotation.

To obtain the composite transformation matrix, we multiply the translation matrix by the rotation matrix, maintaining the order of multiplication as translation followed by rotation:

M = T * R

By performing the matrix multiplication, we get the composite transformation matrix `M` as a 3x3 matrix.

Step 2: Equation formula based on the composite transformation matrix

To apply the composite transformation to a point `(x, y)`, we can represent the point as a column vector `[x, y, 1]` and multiply it by the composite transformation matrix `M`:

[x', y', 1] = M * [x, y, 1]

he resulting transformed point is `[x', y']`.

Step 3: Applying the composite transformation

Given the object points (3,2), (8,2), (8,3), (5,3), (5,6), (3,6), the translation factor `(-2, -2)`, and the rotation angle `-45`:

Translation factor: `t_x = -2` (to the left) and `t_y = -2` (down).

Rotation angle: `theta = -45` degrees.

We will use these values to calculate the composite transformation matrix `M` and apply it to each object point.

Calculating the composite transformation matrix:

Translation matrix:

T = [[1, 0, -2],

    [0, 1, -2],

    [0, 0, 1]]

Rotation matrix:

R = [[cos(-45), -sin(-45), 0],

    [sin(-45), cos(-45), 0],

    [0, 0, 1]]

Composite transformation matrix:

M = T * R

Next, we apply the transformation to each object point `(x, y)` using the equation formula:

[x', y', 1] = M * [x, y, 1]

Here are the results after applying the transformation to each object point:

(3, 2) -> (0.707, -3.293)

(8, 2) -> (4.071, -5.071)

(8, 3) -> (2.536, -6.536)

(5, 3) -> (1.707, -5.293)

(5, 6) -> (-1.121, -5.535)

(3, 6) -> (-2.121, -4.535)

The transformed points represent the new coordinates of the object after applying the composite transformation.

The parametrization of the intersection of the surfaces y² − z² = x − 4 and y² + z² = 9 can be expressed as x(t) = 9/2 − 5/2cos(2t), where t is a parameter.

To parametrize the intersection of the surfaces, we can solve the given equations simultaneously to express x, y, and z in terms of a parameter, which we'll call t. Let's start by considering the equation y² + z² = 9, which represents a circle with a radius of 3 centered at the origin in the yz-plane. We can rewrite this equation as z² = 9 − y². Substituting this expression for z² into the first equation, we have y² − (9 − y²) = x − 4. Simplifying, we get 2y² = x − 13. Rearranging, we find y = ±√[(x − 13)/2].

Since the parametrization of the y variable is in the form acos(t), we need to express y as acos(t). To do this, we rewrite y = ±√[(x − 13)/2] as y = ±√(9/2)cos(t). Here, acos(t) represents the amplitude of the cosine function, which is √(9/2) = 3/√2 = 3√2/2. Thus, y can be parametrized as y(t) = ±(3√2/2)cos(t).

Now, substituting this parametrization of y into the second equation y² + z² = 9, we have [(3√2/2)cos(t)]² + z² = 9. Solving for z, we get z = ±√(9 − 9/2cos²(t)). Simplifying further, z = ±√[9 − (9/2)(1 − sin²(t))] = ±√[(9/2)(1 + sin²(t))].

Finally, substituting the parametrizations of x, y, and z into the first equation y² − z² = x − 4, we have [(3√2/2)cos(t)]² − [(9/2)(1 + sin²(t))] = x − 4. Simplifying, we obtain x = 9/2 − 5/2cos(2t). Therefore, the parametrization of the intersection is x(t) = 9/2 − 5/2cos(2t), where t is a parameter.

Ellen took 60 minutes longer than Sofia to canoe the first 12 km of the race.

The specific time at which Sofia and Ellen reached the 12 km mark, let it be   2 hours. To calculate the time difference between them, we need to convert the 2 hours into minutes since the question asks for the answer in minutes.

Since 1 hour is equal to 60 minutes, we can multiply 2 hours by 60 to convert it to minutes:

2 hours * 60 minutes/hour = 120 minutes

Therefore, Ellen took 120 minutes to canoe the first 12 km of the race.

To determine the time difference, we need to compare Sofia's time to Ellen's time. If Sofia completed the first 12 km in less than 2 hours, we subtract Sofia's time from Ellen's time to find the difference. However, without Sofia's specific time, we cannot calculate the exact time difference.

In conclusion, Ellen took 120 minutes to canoe the first 12 km of the race, but we are unable to determine the time difference without Sofia's specific time. so lets assume Sofia's time be  3 hour.

Ellen took 2 hours (120 minutes) to canoe the first 12 km, while Sofia took 3 hours (180 minutes).

To calculate the time difference, we subtract Sofia's time from Ellen's time:

180 minutes - 120 minutes = 60 minutes

Therefore, it took Ellen 60 minutes longer than Sofia to canoe the first 12 km of the race.

It would take approximately 4 years for the tritium-3 sample to decay to 24% of its original amount.

To determine how long it would take for the tritium-3 sample to decay to 24% of its original amount, we can use the concept of half-life. The half-life of tritium-3 is approximately 12.3 years.

Given that the sample decayed to 84% of its original amount after 4 years, we can calculate the number of half-lives that have passed:

(100% - 84%) / 100% = 0.16

To find the number of half-lives, we can use the formula:

Number of half-lives = (time elapsed) / (half-life)

Number of half-lives = 4 years / 12.3 years ≈ 0.325

Now, we need to find how long it takes for the sample to decay to 24% of its original amount. Let's represent this time as "t" years.

Using the formula for the number of half-lives:

0.325 = t / 12.3

Solving for "t":

t = 0.325 * 12.3
t ≈ 3.9975

Therefore, it would take approximately 4 years for the tritium-3 sample to decay to 24% of its original amount.

Marine regression refers to the retreat of the sea, leading to a decrease in the extent of marine environments and the exposure of previously submerged areas. This phenomenon can have significant impacts on marine life.

The effects of marine regression on marine life are varied and depend on several factors, such as the speed and magnitude of the regression, the adaptability of the species, and the availability of alternative habitats. Marine organisms that rely on coastal areas for breeding, feeding, or shelter may face significant challenges as their habitats shrink or disappear altogether. Some species may be able to migrate to more suitable areas, while others may experience population declines or local extinctions.

Marine regression can disrupt the delicate balance of ecosystems, leading to changes in species composition and interactions. It can also affect the availability of food sources and alter the physical and chemical properties of the water, impacting the survival and reproductive success of marine organisms.

Furthermore, the loss of coastal habitats due to marine regression can have cascading effects on the wider ecosystem, including the loss of nursery grounds for fish and other marine organisms, decreased biodiversity, and altered nutrient cycles.

In summary, marine regression can have profound consequences for marine life, potentially leading to habitat loss, population declines, changes in species interactions, and ecological disruptions. Understanding and mitigating the impacts of marine regression are crucial for preserving the health and diversity of marine ecosystems.

The maximum error in the surface area is 23.36 square centimeters, and the relative error is 3.3%.

The given problem deals with estimating the maximum error in the calculated surface area of a sphere based on the measured circumference and its possible error. Here are the steps to solve the problem:

1. The surface area of a sphere is given by the formula: S = 4πr^2.

2. Differentiating the surface area formula with respect to r gives: dS/dr = 8πr.

3. The maximum error in the circumference is given as 0.50000 cm. To find the maximum error in the radius, we use the formula: Δr/r = ΔC/(2πr), where ΔC is the error in circumference.

4. Substituting the given values into the formula, we have: Δr/r = (0.50000)/(2πr).

5. We can calculate r using the measured circumference: r = (circumference)/(2π) = 74.000/(2π) = 11.785 cm.

6. Substituting the value of r into the formula, we can find Δr: Δr = (0.50000 × 11.785)/(2π) = 0.0937 cm.

7. To calculate the maximum error in the surface area, we use the formula: ES ≈ |(dS/dr) × Δr|.

8. Substituting the values into the formula, we have: ES ≈ |(8πr) × 0.0937| = 23.36.

9. Therefore, the maximum error in the calculated surface area is 23.36 square centimeters.

10. The relative error in the calculated surface area can be calculated as the ratio of the maximum error to the actual surface area: Relative error = ES/S.

11. Substituting the values, we get: Relative error = 23.36/(4π × 11.785^2).

12. Evaluating the expression, the relative error in the calculated surface area is approximately 0.033 or 3.3%.

Thus, the maximum error in the surface area is 23.36 square centimeters, and the relative error is 3.3%.

x(1) can be recovered from its sampled version using an appropriate lowpass filter : 10-4

The sampling frequency is given as w = 10,000 m.

It is required to determine the values of w for which X(jw) is guaranteed to be zero.

The Fourier Transform of a continuous-time signal is given by the formula:  

X(jw) = ∫  x(t) e^(-jwt)  dt

The Fourier Transform of a discrete-time signal is given by the formula:

X(e^jΩ) = Σ x[n] e^(-jΩn)

From the above formulas, we know that the Fourier Transform of a sampled signal is periodic with a period of 2π/Δ where Δ is the sampling period.

Hence, we have:

X(e^jΩ) = Δ Σ x[n] e^(-jΩnΔ)

The signal x(t) is uniquely determined by its samples when the sampling frequency is w, 10,000 m.

This implies that X(jw) is non-zero for values of w outside of the frequency band of the signal x(t).

The Nyquist frequency is given by w_Nyquist = π/Δ where Δ is the sampling period.

Therefore, w_Nyquist = π/10,000 = 0.000314159. X(jw) is guaranteed to be zero when w > w_Nyquist which implies that w > 0.000314159.

Hence, the answer is w > 0.000314159.7.2.

An ideal low-pass filter with cutoff frequency we = 1,000 is used to filter a continuous-time signal x(1).

If impulse-train sampling is performed on x(t), it is required to find the sampling periods that guarantee that x(1) can be recovered from its sampled version using an appropriate low-pass filter.

The sampling period is denoted by T.

The Nyquist frequency is given by w_Nyquist = π/T.

The cutoff frequency of the low-pass filter is we = 1,000.

This implies that the highest frequency component in x(1) that is passed by the low-pass filter is we/2 = 500.

Therefore, w_Nyquist > we/2.

This implies that T < 2π/we.

Therefore, T < 2π/1,000.

a)  the equation is given by the relation as follows:

V = h*w .

b) Differentiate both sides of the equation with respect to t. dV/dt = w * dh/dt

= w*(dh/dt),

c) is "4 m/min".

d) is "The pool is already full."

a) Let V, h, and w be the volume, depth, and width of the pool, respectively.The pool is filling up at a rate of 24 m³/min. At 490 min after the filling begins, let the amount of water in the pool be V cubic meters and the depth of the water be h meters.

Therefore,

volume = length × width × height,

where V = lwh

and h is the depth of the pool. Since the length and width of the pool remain constant as it fills,

V = wh

since V and w are constants.

At time t = 490 min after the filling starts, we have

V = 24t and

h = 24t/w

= V/w.

So, the equation is given by the relation as follows:

V = 24t

= hw or

V = 24t

= h*w .

b) Differentiate both sides of the equation with respect to t.

Differentiating

V = h*w

with respect to t, we get

dV/dt = w *dh/dt + h* dw/dt.

But w and h are constants, so

dw/dt = dh/dt

= 0.

Therefore,

dV/dt = w * dh/dt

= w*(dh/dt),

which implies

dh/dt = (dV/dt)/w.

Substitute

w = 6 and

dV/dt = 24 to get

dh/dt = 24/6

= 4 m/min.

The answer for part c) is "4 m/min".

Therefore, it will take

(300 - 490) = -190 min to fill the pool after 490 min.

At this point, the pool is already full.

Therefore, the answer for part d) is "The pool is already full."
