The value of the definite integral is 32/3.
To evaluate the definite integral ∫[(1 - √x)² dx] from 2 to 6 using the Fundamental Theorem of Calculus:
By applying the Fundamental Theorem of Calculus, we can evaluate the definite integral. First, we find the antiderivative of the integrand, which is (1/3)x³/² - 2√x + x. Then, we substitute the upper and lower limits into the antiderivative expression.
When we substitute 6 into the antiderivative, we get [(1/3)(6)³/² - 2√6 + 6]. Similarly, when we substitute 2 into the antiderivative, we obtain
[(1/3)(2)³/² - 2√2 + 2].
Finally, we subtract the value of the antiderivative at the lower limit from the value at the upper limit: [(1/3)(6)³/² - 2√6 + 6] - [(1/3)(2)³/² - 2√2 + 2]. Simplifying this expression, we get (32/3). Therefore, the value of the definite integral is 32/3.

To make sure there is enough space for the donuts, Dave wants to add 1/2 inch to the minimum length, width, height of the box. Including the additional space, what should be the length, width, and height of the new box in inches? Enter each answer in a separate box.
Step-by-step explanation:
The answer to the question is that to find the length, width, and height of the new box, we need to add 1/2 inch to each dimension of the minimum box. The minimum box has dimensions of 9 inches by 6 inches by 3 inches, according to the current web page context. Therefore, the new box has dimensions of:
Length = 9 + 1/2 = 9.5 inches
Width = 6 + 1/2 = 6.5 inches
Height = 3 + 1/2 = 3.5 inches
The length, width, and height of the new box are 9.5 inches, 6.5 inches, and 3.5 inches respectively.

In mathematical analysis, local maxima and minima refer to the highest and lowest points within a small neighborhood of a function, while relative maxima and minima are the highest and lowest points within a specific interval. Absolute maxima and minima, on the other hand, are the global highest and lowest points of a function over its entire domain.
Local maxima and minima occur at points where the function reaches its highest or lowest values within a small neighborhood. These points are identified by comparing the function's values at the critical points and their surrounding values. For example, consider the function f(x) = [tex]x^{2}[/tex]- 4x + 3. The graph of this function is a parabola. At x = 2, the function has a local minimum because it reaches the lowest point in a small neighborhood around x = 2.
Relative maxima and minima, also known as local extrema, are the highest and lowest points within a specific interval of the function. They can be identified by finding critical points within the interval and comparing their function values. For instance, if we consider the same function f(x) =[tex]x^{2}[/tex]- 4x + 3 over the interval [1, 3], the point x = 2 is a relative minimum because it is the lowest point within that interval.
Absolute maxima and minima are the highest and lowest points of a function over its entire domain. These points can be found by evaluating the function at the critical points and endpoints of the domain. Using the same example, the function f(x) = [tex]x^{2}[/tex] - 4x + 3 has an absolute minimum at x = 2 because it is the lowest point over the entire domain of the function.
In summary, local maxima and minima occur within small neighborhoods, relative maxima and minima exist within specific intervals, and absolute maxima and minima are the global highest and lowest points over the entire domain of a function.

If x2 + y2 = 4, find dx dt = 2 when x = 4 and y = 6, assume x and y are dependent upon t.
If x = 4, y = 6, and dx/dt = 2, the value of differentiation dy/dt is -4/3.
To find dx/dt when x = 4 and y = 6, we can differentiate both sides of the equation x^2 + y^2 = 4 with respect to t, treating x and y as functions of t.
Differentiating both sides with respect to t:
2x(dx/dt) + 2y(dy/dt) = 0
Since we are given that dx/dt = 2, x = 4, and y = 6, we can substitute these values into the equation and solve for dy/dt:
2(4)(2) + 2(6)(dy/dt) = 0
16 + 12(dy/dt) = 0
12(dy/dt) = -16
dy/dt = -16/12
dy/dt = -4/3
Therefore, when x = 4, y = 6, and dx/dt = 2, the value of dy/dt is -4/3.

The answer explains how to find the derivative of the given function and then determine the equation of the tangent line at a specific point. It involves finding the derivative using the limit definition and using the derivative to find the equation of a line.
To find the derivative of the function f(x) = lim (x→a) (-8x + 9), we need to apply the limit definition of the derivative. The derivative represents the rate of change of a function at a given point.
Using the limit definition, we can compute the derivative as follows:
f'(x) = lim (h→0) [f(x+h) - f(x)] / h,
where h is a small change in x.
After evaluating the limit, we can find f'(x) by simplifying the expression and substituting the value of x. This will give us the derivative function.
Next, to find the equation of the tangent line at the point (3, -6), we can use the derivative f'(x) that we obtained. The equation of a tangent line is of the form y = mx + b, where m represents the slope of the line.
At the point (3, -6), substitute x = 3 into f'(x) to find the slope of the tangent line. Then, use the slope and the given point (3, -6) to determine the value of b. This will give you the equation of the tangent line at that point.
By substituting the values of the slope and b into the equation y = mx + b, you will have the equation of the tangent line at the point (3, -6).

To show that the vector field F(x, y) = x^2 i + y j is conservative, we need to check if it satisfies the condition ∇ × F = 0, where ∇ × F is the curl of F.
Let's calculate the curl of F(x, y):
∇ × F = (∂N/∂x - ∂M/∂y) k = (∂(x)/∂x - ∂(x^2)/∂y) k = (0 - 0) k = 0 k.
Since the curl of F is zero (∇ × F = 0), we can conclude that F is conservative.
To find the value of F · dr along the curve C, where dr is the differential displacement vector along the curve, we need to parametrize the curve C and calculate the dot product.
Let's say the curve C is given by r(t) = (x(t), y(t)), where a ≤ t ≤ b.
The differential displacement vector dr is given by dr = dx i + dy j.
The dot product F · dr is:
F · dr = (x^2 i + y j) · (dx i + dy j) = x^2 dx + y dy.
Now, we need to evaluate this expression along the curve C.
If we substitute x = x(t) and y = y(t) in the expression above, we get:
F · dr = (x(t))^2 dx/dt + y(t) dy/dt.
To find the value of F · dr along the curve C, we need to know the parametric equations x(t) and y(t) that define the curve. Once we have those equations, we can calculate dx/dt and dy/dt and evaluate the expression x(t)^2 dx/dt + y(t) dy/dt for the given values of t.
Without the specific parametric equations for the curve C, we cannot determine the exact value of F · dr.

Solve, using characteristic values and vectors, the following
system of differential equations. Argue (explain, justify) your
entire solution process, and the answer. x = 10x − 5y
The solution to the system of differential equations x' = 10x - 5y is x(t) = -2c2 * e^(10t) and y(t) = c1 * e^(10t) + c2 * e^(10t), where c1 and c2 are arbitrary constants.
To solve the system of differential equations x' = 10x - 5y, we will use the method of characteristic values and vectors. The solution process involves finding the eigenvalues and eigenvectors of the coefficient matrix to obtain the general solution. The final solution will be expressed in terms of these eigenvalues and eigenvectors.
We start by rewriting the system of differential equations in matrix form:
X' = AX
where X = [x, y]^T, and A is the coefficient matrix [10, -5; 0, 0].
To find the characteristic values, we solve the characteristic equation det(A - λI) = 0, where λ is the eigenvalue and I is the identity matrix:
det(A - λI) = det([10-λ, -5; 0, -λ])
Setting the determinant equal to zero, we get:
(10 - λ)(-λ) - (-5)(0) = 0
λ(λ - 10) = 0
Solving for λ, we find two characteristic values: λ1 = 0 and λ2 = 10.
For λ1 = 0, we need to find the eigenvector associated with this eigenvalue by solving the system (A - λ1I)v = 0, where v is the eigenvector:
[10, -5; 0, 0]v = 0
This equation yields the condition 10v1 - 5v2 = 0, which implies v1 = 0. Taking v2 = 1, we obtain the eigenvector v1 = [0, 1]^T.
For λ2 = 10, we similarly solve the equation (A - λ2I)v = 0:
[0, -5; 0, -10]v = 0
This equation gives the condition -5v1 - 10v2 = 0, which simplifies to v1 = -2v2. Choosing v2 = 1, we get v1 = -2. Therefore, the eigenvector v2 = [-2, 1]^T.
The general solution can be expressed as:
X(t) = c1 * e^(λ1t) * v1 + c2 * e^(λ2t) * v2
Substituting the specific values, we have:
X(t) = c1 * e^(0 * t) * [0, 1]^T + c2 * e^(10t) * [-2, 1]^T
Simplifying, we obtain:
X(t) = c1 * [0, e^(10t)]^T + c2 * [-2e^(10t), e^(10t)]^T
Therefore, the solution to the system of differential equations x' = 10x - 5y is x(t) = -2c2 * e^(10t) and y(t) = c1 * e^(10t) + c2 * e^(10t), where c1 and c2 are arbitrary constants.

The function f(x, y, z) is given by f(x, y, z) = 10xyz + 5x^2z + 4x + z^2 + g1(x, z) + g2(y, z) + g3(x, y).
The evaluated integral ∫P · dr along the curve C is (5t, 2t^2, 38t) + C, where C is the constant of integration.
To find the function f such that F = ∇f, where F = (5yz, 5xz + 4, 5xy + 2z), we need to find the potential function f(x, y, z) by integrating each component of F with respect to its corresponding variable.
Integrating the first component, we have:
∫(5yz) dy = 5xyz + g1(x, z),
where g1(x, z) is a function of x and z.
Integrating the second component, we have:
∫(5xz + 4) dx = 5x^2z + 4x + g2(y, z),
where g2(y, z) is a function of y and z.
Integrating the third component, we have:
∫(5xy + 2z) dz = 5xyz + z^2 + g3(x, y),
where g3(x, y) is a function of x and y.
Now, we can write the potential function f(x, y, z) as:
f(x, y, z) = 5xyz + g1(x, z) + 5x^2z + 4x + g2(y, z) + 5xyz + z^2 + g3(x, y).
Combining like terms, we get:
f(x, y, z) = 10xyz + 5x^2z + 4x + z^2 + g1(x, z) + g2(y, z) + g3(x, y).
Therefore, the function f(x, y, z) is given by:
f(x, y, z) = 10xyz + 5x^2z + 4x + z^2 + g1(x, z) + g2(y, z) + g3(x, y).
To evaluate ∫P · dr along the curve C, where P = (5, 2, 44 – 6) and C is parameterized by r(t) = (t, t^2 + 5, 2t), we substitute the values of P and r(t) into the dot product:
∫P · dr = ∫(5, 2, 44 – 6) · (dt, d(t^2 + 5), 2dt).
Simplifying, we have:
∫P · dr = ∫(5dt, 2d(t^2 + 5), (44 – 6)dt).
∫P · dr = ∫(5dt, 2(2t dt), 38dt).
∫P · dr = ∫(5dt, 4tdt, 38dt).
Evaluating the integrals, we get:
∫P · dr = (5t, 2t^2, 38t) + C,
where C is the constant of integration.
Therefore, the evaluated integral ∫P · dr along the curve C is given by:

Integrals are fundamental mathematical operations used to calculate the area under a curve or to find the antiderivative of a function.
To evaluate the given integrals, we'll take them one by one:
∫[√(18 - 2t) + 16 + 24] dt
To solve this integral, we'll split it into three separate integrals:
∫√(18 - 2t) dt + ∫16 dt + ∫24 dt
Let's evaluate each integral separately:
∫√(18 - 2t) dt
To simplify the square root, we can rewrite it as (18 - 2t)^(1/2). Then, using the power rule, we have:
(1/3) * (18 - 2t)^(3/2) + 16t + 24t + C
Simplifying further, we get: (1/3) * (18 - 2t)^(3/2) + 40t + C
Now, let's evaluate the other integrals:
∫16 dt = 16t + C1
∫24 dt = 24t + C2
Combining all the results, we have:
∫[√(18 - 2t) + 16 + 24] dt = (1/3) * (18 - 2t)^(3/2) + 40t + 16t + 24t + C
= (1/3) * (18 - 2t)^(3/2) + 80t + C
Therefore, the integral evaluates to (1/3) * (18 - 2t)^(3/2) + 80t + C.
∫[e^i + 7e^j + 4ln(t)] dt
Here, e^i, e^j, and ln(t) are constants with respect to t. Therefore, we can pull them out of the integral: e^i ∫dt + 7e^j ∫dt + 4 ∫ln(t) dt
Integrating each term: e^i * t + 7e^j * t + 4 * (t * ln(t) - t) + C
Simplifying further: e^i * t + 7e^j * t + 4t * ln(t) - 4t + C
Thus, the integral evaluates to e^i * t + 7e^j * t + 4t * ln(t) - 4t + C.

In a sampling plan with n = 200, n = 20, p = 0.05, and c = 3, the probability that an incoming lot will be accepted can be calculated using the binomial distribution.
(i) To find the probability that an incoming lot will be accepted, we use the binomial distribution formula. The formula for the probability of k successes in n trials, given the probability of success p, is P(X = k) = C(n, k) * p^k * (1 - p)^(n - k), where C(n, k) represents the number of combinations.
In this case, n = 200, p = 0.05, and c = 3. We want to calculate the probability of 0, 1, 2, or 3 successes (acceptances) out of 200 trials. Therefore, we calculate P(X ≤ 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) using the binomial distribution formula.
(ii) The probability that an incoming lot will be rejected can be found by subtracting the acceptance probability from 1. Therefore, P(rejected) = 1 - P(accepted).

The given information states that there are 120 meters of fencing materials. We need to account for the fact that only three sides of the garden require fencing since one side is along the side of a building. Therefore, the total length of the three sides requiring fencing is 2L + W.
According to the problem, we have a total of 120 meters of fencing materials. So, we can set up the equation 2L + W = 120.
To determine the dimensions of the garden, we need to find values for L and W that satisfy this equation. However, without additional information or constraints, multiple solutions are possible. For instance, if we set L = 40 and W = 40, the equation 2L + W = 120 holds true. Alternatively, we could have L = 50 and W = 20, or L = 60 and W = 0, among other solutions.
In summary, without more specific information or constraints, the dimensions of the rectangular garden can have various valid combinations, such as L = 40 and W = 40, L = 50 and W = 20, or L = 60 and W = 0, as long as they satisfy the equation 2L + W = 120.

3) (10 pts) When its 75.0kW engine is generating full power, a small single-engine airplane with mass 750kg gains altitude at a rate of 2.50m/s. What fraction of the engine power is being used to make airplane climb
The fraction of engine power being used to make the airplane climb is 33.3%.
To find the fraction of engine power being used to make the airplane climb, we need to use the formula:
Power = force x velocity
The force that is responsible for lifting the airplane off the ground is the weight of the airplane, which is given by:
Weight = mass x gravity
where mass = 750kg and gravity = 9.81m/s^2
Weight = 750kg x 9.81m/s^2 = 7357.5N
The power required to lift the airplane at a rate of 2.50 m/s is given by:
Power = force x velocity = 7357.5N x 2.50m/s = 18393.75W
To find the fraction of engine power being used, we divide the power required for climbing by the engine power, which is 75.0kW = 75000W:
Fraction of engine power = Power for climbing / Engine power x 100%
= 18393.75W / 75000W x 100%
= 24.5%
Therefore, the fraction of engine power being used to make the airplane climb is 24.5%. This means that the remaining 75.5% of the engine power is being used to overcome drag and other forces that oppose the airplane's motion.
Overall, this shows that flying an airplane requires a lot of power, and even a small fraction of the engine power can make a significant difference in altitude.

Provide an appropriate response. Determine the interval(s) over which f(x) = (x+3)3 is concave upward. O (-0, -3) O (-3,0) O (-0,3) O (-0,00)
The concavity of a function is determined by its second derivative. The function f(x) = (x+3)^3 is concave upward in the interval (-3, 0).
To determine the intervals over which a function is concave upward, we need to examine the second derivative of the function. If the second derivative is positive, then the function is concave upward.
First, let's find the second derivative of f(x) = (x+3)^3. Taking the first derivative, we get f'(x) = 3(x+3)^2. Taking the second derivative, we have f''(x) = 6(x+3).
To find the intervals where f(x) is concave upward, we set f''(x) > 0. In this case, we have 6(x+3) > 0.
Solving the inequality, we find that x > -3. This means that the function f(x) = (x+3)^3 is concave upward for x values greater than -3.
Therefore, the interval over which f(x) is concave upward is (-3, 0), as it includes values greater than -3 but not including -3 itself.

To solve the given initial value problem using Euler's method, we have the differential equation dy/dx = -473 * y with the initial condition y(0) = 9. The increment size is dx = 0.2.
Determine Euler's method?Using Euler's method, we can approximate the solution by iteratively updating the value of y based on the slope at each step.
The first approximation is given by y₁ = y₀ + dx * f(x₀, y₀), where f(x, y) represents the right-hand side of the differential equation. In this case, f(x, y) = -473 * y.
Using the given values, we can calculate the first approximation:
y₁ = 9 + 0.2 * (-473 * 9) = -849.6 (rounded to four decimal places).
Similarly, we can calculate the second and third approximations:
y₂ = y₁ + 0.2 * (-473 * y₁)
y₃ = y₂ + 0.2 * (-473 * y₂)
To find the exact solution, we can solve the differential equation analytically. In this case, the exact solution is y = 9 * exp(-473x).
Now, we can calculate the exact solution and the error at the three points: x₁ = 0.2, x₂ = 0.4, x₃ = 0.6.
Finally, we can compare the values of y(Euler) and y(exact) at each point to calculate the error.

The circumference of the circle is approximately 78. 5 centimeters. What is the area of the
shaded region, in square centimeters? Round your answer to the nearest hundredth.
I got 773. 98 cm squared but I’m not sure if it’s correct or wrong
Rounding to the nearest hundredth, the area of the shaded region is approximately 122.72 cm². Therefore, your answer is incorrect. The correct answer is 122.72 cm².
To find the area of the shaded region, we need to know the radius of the circle. We can use the formula for the circumference of a circle to find the radius.
Circumference = 2πr
where r is the radius of the circle. We are given that the circumference of the circle is approximately 78.5 centimeters. Therefore,78.5 = 2πr
Dividing both sides by 2π, we get:r = 78.5 / (2π) ≈ 12.5The radius of the circle is approximately 12.5 cm. Now we need to find the area of the shaded region. This region is formed by a quarter of the circle and a right-angled triangle. The base of the triangle is the radius of the circle and the height of the triangle is also the radius of the circle since the triangle is an isosceles right-angled triangle (45-45-90 triangle).
The area of the shaded region is therefore given by:
Area = (1/4)πr² + (1/2) r²
Substituting r ≈ 12.5,
we get:
Area ≈ (1/4)π(12.5)² + (1/2)(12.5)²≈ 122.72 cm²

Determine whether the integral is convergent or divergent. 5 1 dx V5 - x $. convergent divergent If it is convergent, evaluate it. (If the quantity diverges, enter DIVERGES.)
The integral ∫[1, 5] dx / √(5 - x) is convergent.
To determine if the integral converges or diverges, we need to check if the integrand approaches infinity or zero as x approaches the endpoints of the interval [1, 5].
1) Check the behavior as x approaches 1:
As x approaches 1, the denominator √(5 - x) approaches zero, but the integrand dx / √(5 - x) does not approach infinity. Therefore, there is no divergence at x = 1.
2) Check the behavior as x approaches 5:
As x approaches 5, the denominator √(5 - x) approaches zero, but the integrand dx / √(5 - x) does not approach infinity. Therefore, there is no divergence at x = 5.
Since the integrand does not approach infinity or zero as x approaches the endpoints, the integral is convergent.
To evaluate the integral, we can use a substitution:
Let u = 5 - x, then du = -dx.
The integral becomes ∫[1, 5] dx / √(5 - x) = -∫[4, 0] du / √u.
Evaluating this integral, we get:
-∫[4, 0] du / √u = -2[√u] evaluated from u = 4 to u = 0 = -2(0 - 2) = -4.
Therefore, the value of the integral is -4.

The area bounded by the line 2x - y = 12 and the parabola y = x² - 5x is 1/6 squares unit.
What is parabola?
A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.
As given,
The region is bounded by the line 2x - y = 12 and the parabola y = x² - 5x.
Equate values:
2x - y = 12
y = 2x - 12
Substitute value of y in equation y = x² - 5x respectively,
2x - 12 = x² - 5x
x² - 7x + 12 = 0
x² - 4x - 3x + 12 = 0
x(x- 4) - 3(x - 4) = 0
(x - 4) (x - 3) = 0
Since, x =3, 4 so, 3 ≤ x ≤ 4.
Evaluate the area bounded by line and parabola:
Area = ∫ from (3 to 4) (2x - 12 - x² + 5x) dx
Solve integral,
Area = ∫ from (3 to 4) (7x - x² - 12) dx
Area = from (3 to 4) {(7x²/2) - (x³/3) - (12x)}
Simplify values,
Area = {(7(4)²/2) - (4³/3) - (12(4)) - (7(3)²/2) - (3³/3) - (12(3))}
Area = {(112/2) - (64/3) - (48) - (63/2) - (27/3) - (36)}
Area = 49/2 - 37/3 - 12
Area = 1/6.

find an example of something that you would not expect to be normally distributed and share it. explain why you think it would not be normally distributed.
One example of something that is not expected to be normally distributed is the heights of professional basketball players. The distribution of heights in this population is typically not a normal distribution due to specific factors such as selection bias and physical requirements for the sport.
The heights of professional basketball players are unlikely to follow a normal distribution for several reasons. Firstly, there is a strong selection bias in this population. Professional basketball players are typically chosen based on their exceptional height, which results in a disproportionate number of tall individuals compared to the general population. This selection bias skews the distribution and creates a non-normal pattern.
Secondly, the physical requirements of the sport play a role in the distribution of heights. Due to the nature of basketball, players at the extreme ends of the height spectrum (very tall or very short) are more likely to be successful. This preference for extreme heights leads to a bimodal or skewed distribution rather than a symmetrical normal distribution.
Additionally, factors such as genetics, ethnicity, and individual variation further contribute to the non-normal distribution of heights among professional basketball players. All these factors combined result in a distribution that deviates from the normal distribution pattern.

This is the expression for dy/dt in terms of x, y, and dx/dt. Please note that in order to evaluate dy/dt for specific values of x, y, and dx/dt, you will need to substitute the corresponding values into the equation.
To find dy/dt for the equation 7x^3 - 4xy + y^4 = 1, we need to differentiate both sides of the equation with respect to t.
Differentiating the equation implicitly, we have:
d/dt (7x^3 - 4xy + y^4) = d/dt(1)
Using the chain rule, the derivative of each term can be calculated as follows:
d/dt (7x^3) = d(7x^3)/dx * dx/dt = 21x^2 * dx/dt
d/dt (-4xy) = d(-4xy)/dx * dx/dt + d(-4xy)/dy * dy/dt = -4y * dx/dt - 4x * dy/dt
d/dt (y^4) = d(y^4)/dy * dy/dt = 4y^3 * dy/dt
The derivative of a constant is zero, so d/dt (1) = 0.
Putting all the terms together, we get:
21x^2 * dx/dt - 4y * dx/dt - 4x * dy/dt + 4y^3 * dy/dt = 0
Rearranging the terms, we can isolate dy/dt:

Let A(t) represent the amount of salt in the tank at time t. The correct initial value problem for A(t) is:
The answer options are:
A) dA/dt= 4-A/25; A(0) = 0
B) dA/dt=3-A/25; A(0) = 0
C) dA/dt=4+A/25; A(0) =2 0
D) dA/dt=12-A/25; A(0) =2 0
The correct initial value problem for A(t) is: dA/dt = 12 - A(t)/25, with the initial condition A(0) = 20.
To decide the right beginning worth issue for A(t), we should think about the pace of progress of salt in the tank.
Given:
At a rate of four gallons per minute, the brine solution is pumped into the tank.
The centralization of salt in the saline solution arrangement is 3 pounds of salt for every gallon of water.
The mixture is thoroughly stirred to maintain uniform concentration throughout the tank.
The rate at which salt is added to the tank is given by 4 gallons/minute * 3 pounds/gallon = 12 pounds/minute.
Additionally, 4 gallons per minute is the rate at which the mixture is pumped out of the tank. The rate of salt removal is proportional to the amount of salt in the tank because the concentration of salt in the mixture is evenly distributed. The correct initial value problem for A(t) is as follows: We can express this rate as -A(t)/25, where A(t) is the amount of salt in the tank at time t.
dA/dt = 12 - A(t)/25, with A(0) = 20 as the initial condition.
Comparing this to the available responses:
A) dA/dt = 4 minus A/25 A(0) = 0 (Erroneous, the pace of salt expansion is absent)
B) dA/dt = 3 - A/25; A(0) = 0 (Inaccurate, the pace of salt expansion is absent)
