There are polynomials that satisfy the condition p = p^2, and W is not empty. Hence, statement D is correct answer,

To analyze the set W, which consists of all 1st degree polynomials (or less) such that p = p^2, we will consider each statement and determine its validity.

Statement A: W is closed under scalar multiplication.

For a set to be closed under scalar multiplication, multiplying any element of the set by a scalar should result in another element of the set. In this case, let's consider a polynomial p = ax + b, where a and b are constants.

To test the closure under scalar multiplication, we need to multiply p by a scalar k:

kp = k(ax + b) = kax + kb

Notice that kp is still a 1st degree polynomial (or less) because the highest power of x in the resulting polynomial is 1. Therefore, W is closed under scalar multiplication. This makes statement A true.

Statement B: W doesn't contain the zero vector.

The zero vector in this case would be the polynomial p = 0. However, if we substitute p = 0 into the equation p = p^2, we get:

0 = 0^2

This equation is true for all values of x, indicating that the zero vector (p = 0) satisfies the condition p = p^2. Therefore, W does contain the zero vector. Hence, statement B is false.

Statement C: W is NOT closed under addition.

For a set to be closed under addition, the sum of any two elements in the set should also be an element of the set. In this case, let's consider two polynomials p1 = a1x + b1 and p2 = a2x + b2, where a1, a2, b1, and b2 are constants.

If we add p1 and p2:

p1 + p2 = (a1x + b1) + (a2x + b2) = (a1 + a2)x + (b1 + b2)

The resulting polynomial is still a 1st degree polynomial (or less) because the highest power of x in the sum is 1. Therefore, W is closed under addition. Thus, statement C is false.

Statement D: W is empty.

To determine if W is empty, we need to find if there are any polynomials that satisfy the condition p = p^2.

Let's consider a general 1st degree polynomial p = ax + b:

p = ax + b

p^2 = (ax + b)^2 = a^2x^2 + 2abx + b^2

To satisfy the condition p = p^2, we need to equate the coefficients of corresponding powers of x:

a = a^2

2ab = 0

b = b^2

From the first equation, we have two possible solutions: a = 0 or a = 1.

If a = 0, then b can be any real number, and we have polynomials of the form p = b. These polynomials satisfy the condition p = p^2.

If a = 1, then we have the polynomial p = x + b. Substituting this into the equation p = p^2:

x + b = (x + b)^2

x + b = x^2 + 2bx + b^2

Equating the coefficients, we get:

1 = 1

2b = 0

b = b^2

The first equation is true for all x, and the second equation gives us b = 0 or b = 1.

Therefore, there are polynomials that satisfy the condition p = p^2, and W is not empty. Hence, statement D is correct option.

To determine the limit of the function[tex]f(x) = (3x + 3x cos(3x)) / (2 sin(3x) cos(3x))[/tex] as x approaches 0, we can simplify the expression and apply the limit property to find the answer.

In order to find the limit of the given function, we can simplify it by canceling out the common factors in the numerator and denominator.

First, let's factor out 3x from the numerator:

[tex]f(x) = (3x(1 + cos(3x))) / (2 sin(3x) cos(3x))[/tex]

Now, we notice that the term (1 + cos(3x)) can be further simplified using the identity: [tex]cos(2θ) = 2cos^2(θ) - 1[/tex]. By substituting θ = 3x, we have:

[tex]1 + cos(3x) = 1 + cos^2(3x) - sin^2(3x) = 2cos^2(3x)[/tex]

Substituting this back into the expression, we get:

[tex]f(x) = (3x * 2cos^2(3x)) / (2 sin(3x) cos(3x))[/tex]

Now, we can cancel out the common factors of 2, sin(3x), and cos(3x) in the numerator and denominator:

[tex]f(x) = (3x * cos^2(3x)) / sin(3x)[/tex]

As x approaches 0, the limit of sin(3x) over x approaches 1, and cos(3x) over x approaches 1. Therefore, the limit of the given function simplifies to:

The marginal profit function is determined by taking the derivative of the revenue function minus the derivative of the cost function. The marginal profit function is P'(x) = 6.76

To find the marginal profit function, we need to calculate the derivative of the revenue and cost functions. The revenue function, R(x), is given as 7x - 0.04x, where x represents the quantity of goods sold. Taking the derivative of R(x) with respect to x, we get R'(x) = 7 - 0.04.

Similarly, the cost function, C(x), is given as 239 + 0.2x. Taking the derivative of C(x) with respect to x, we get C'(x) = 0.2.

To find the marginal profit function, we subtract the derivative of the cost function from the derivative of the revenue function. Thus, the marginal profit function, P'(x), is given by:

P'(x) = R'(x) - C'(x)

= (7 - 0.04) - 0.2

= 6.96 - 0.2

= 6.76.

Therefore, the marginal profit function is P'(x) = 6.76. This represents the rate at which the profit changes with respect to the quantity of goods sold. A positive value indicates an increase in profit, while a negative value indicates a decrease in profit.

To sketch the region R in the xy-plane bounded by the lines x = 0, y = 0, and x + 3y = 3, we can start by plotting these lines.

The line x = 0 represents the y-axis, and the line y = 0 represents the x-axis. We can mark these axes on the xy-plane and the flux of the vector field F = 〈2x, -5, 0〉 across the surface S is approximately -106.5.

Next, let's find the points of intersection between the line x + 3y = 3 and the coordinate axes.

When x = 0, we have:

0 + 3y = 3

3y = 3

y = 1

So, the line x + 3y = 3 intersects the y-axis at the point (0, 1).

When y = 0, we have:

x + 3(0) = 3

x = 3

So, the line x + 3y = 3 intersects the x-axis at the point (3, 0). Plotting these points and connecting them, we obtain a triangular region R in the xy-plane. Now, let's consider the portion S of the plane 2x + 5y + 2z = 12 that is above the region R. Since we want the normal vector n to have a positive z-component, we need to orient the surface S upwards. The normal vector n to the plane is given by 〈2, 5, 2〉. Since we want the positive z-component, we can use 〈2, 5, 2〉 as the normal vector. To find the flux of the vector field F = 〈2x, -5, 0〉 across S, we need to calculate the dot product of F with the normal vector n and integrate it over the surface S. The flux of F across S can be calculated as: Flux = ∬S F · dS

Since the surface S is a plane, the integral can be simplified to:

Flux = ∬S F · n dA

Here, dA represents the differential area element on the surface S. To calculate the flux, we need to set up the double integral over the region R in the xy-plane.

The flux of F across S can be written as: Flux = ∬R F · n dA

Now, let's evaluate the dot product F · n:

F · n = 〈2x, -5, 0〉 · 〈2, 5, 2〉

= (2x)(2) + (-5)(5) + (0)(2)

= 4x - 25

The integral becomes: Flux = ∬R (4x - 25) dA

To evaluate this integral, we need to determine the limits of integration for x and y based on the region R.

Since the lines x = 0, y = 0, and x + 3y = 3 bound the region R, we can set up the limits of integration as follows:

0 ≤ x ≤ 3

0 ≤ y ≤ (3 - x)/3

Now, we can evaluate the flux by integrating (4x - 25) over the region R with respect to x and y using these limits of integration:

Flux = ∫[0 to 3] ∫[0 to (3 - x)/3] (4x - 25) dy dx

Evaluating this double integral will give us the flux of the vector field F across the surface S.

To evaluate the flux of the vector field F = 〈2x, -5, 0〉 across the surface S, we integrate (4x - 25) over the region R with respect to x and y using the given limits of integration: Flux = ∫[0 to 3] ∫[0 to (3 - x)/3] (4x - 25) dy dx

Let's evaluate this double integral step by step:

∫[0 to (3 - x)/3] (4x - 25) dy = (4x - 25) ∫[0 to (3 - x)/3] dy

= (4x - 25) [y] evaluated from 0 to (3 - x)/3

= (4x - 25) [(3 - x)/3 - 0]

= (4x - 25)(3 - x)/3

Now we can integrate this expression with respect to x:

∫[0 to 3] (4x - 25)(3 - x)/3 dx = (1/3) ∫[0 to 3] (4x - 25)(3 - x) dx

Expanding and simplifying the integrand:

(1/3) ∫[0 to 3] (12x - 4x^2 - 75 + 25x) dx

= (1/3) ∫[0 to 3] (-4x^2 + 37x - 75) dx

Integrating term by term:

(1/3) [-4(x^3/3) + (37/2)(x^2) - 75x] evaluated from 0 to 3

= (1/3) [(-4(3^3)/3) + (37/2)(3^2) - 75(3)] - (1/3) [(-4(0^3)/3) + (37/2)(0^2) - 75(0)]

= (1/3) [(-36) + (37/2)(9) - 225]

= (1/3) [-36 + (333/2) - 225]

= (1/3) [-36 + 166.5 - 225]

= (1/3) [-94.5 - 225]

= (1/3) [-319.5]

= -106.5

The first six terms of the Maclaurin series for the function f(x) = 5 ln(1 + x²) - ln 5 can be obtained by expanding the function using the Maclaurin series expansion for ln(1 + x).

The expansion involves finding the derivatives of the function at x = 0 and evaluating them at x = 0.

The Maclaurin series expansion for ln(1 + x) is given by:

ln(1 + x) = x - (x²)/2 + (x³)/3 - (x⁴)/4 + (x⁵)/5 - ...

To find the Maclaurin series for the function f(x) = 5 ln(1 + x²) - ln 5, we substitute x² for x in the expansion:

f(x) = 5 ln(1 + x²) - ln 5

= 5 (x² - (x⁴)/2 + (x⁶)/3 - ...) - ln 5

Taking the first six terms of the expansion, we have:

f(x) ≈ 5x² - (5/2)x⁴ + (5/3)x⁶ - ln 5

The given series, ∑(n=3 to ∞) [7sin(n) + 514/(3m)], diverges in the comparison test.

The series diverges because the terms in the series do not approach zero as n approaches infinity. The presence of the sine function, which oscillates between -1 and 1, along with the constant term 514/(3m), prevents the series from converging. The comparison test can also be applied to analyze the convergence of the series.

To elaborate, let's consider the terms of the series separately. The term 7sin(n) oscillates between -7 and 7 as n increases, indicating a lack of convergence. The term 514/(3m) is a constant value, which also fails to approach zero as n approaches infinity.

Applying the comparison test, we can compare the given series to a known divergent series. For example, if we compare it to the series ∑(n=1 to ∞) 5cos(n), we can see that both terms have similar characteristics. The cosine function oscillates between -1 and 1, just like the sine function, and the constant term 5 in the numerator does not affect the convergence behavior. Since the comparison series diverges, we can conclude that the given series also diverges.

In conclusion, the given series, ∑(n=3 to ∞) [7sin(n) + 514/(3m)], diverges due to the behavior of its terms and the comparison with a known divergent series.

The curl of F is: curl F = -(1/r) * du/dθ i + dv/dz j + (1/r) * (du/dz + dv/dr) k A cylindrical coordinate system is a three-dimensional coordinate system that uses cylindrical coordinates to locate points in space

To find the curl of the velocity field F(x, y, z) in the given cylindrical container, we first need to express F in terms of its component functions. Let's rewrite F as:

F(x, y, z) = -v(x, y, z)i + u(x, y, z)j + 7k

The curl of a vector field F = P i + Q j + R k is given by the following formula:

curl F = (dR/dy - dQ/dz)i + (dP/dz - dR/dx)j + (dQ/dx - dP/dy)k

In this case, P = -v, Q = u, and R = 7. We'll calculate each component of the curl using the given formula.

(dR/dy - dQ/dz) = (d7/dy - du/dz)

(dP/dz - dR/dx) = (dv/dz - d7/dx)

(dQ/dx - dP/dy) = (du/dx - d(-v)/dy)

Since we're dealing with a cylindrical container, the velocity field will have rotational symmetry around the z-axis. Therefore, the velocity components (v, u) will only depend on the radial distance from the z-axis (r) and the height (z). Let's represent the cylindrical coordinates as (r, θ, z).

Taking the partial derivatives, we have:

(dR/dy - dQ/dz) = 0 - (1/r) * du/dθ

(dP/dz - dR/dx) = dv/dz - 0

(dQ/dx - dP/dy) = (1/r) * du/dz - (-1/r) * dv/dr

Now, let's simplify further:

(dR/dy - dQ/dz) = -(1/r) * du/dθ

(dP/dz - dR/dx) = dv/dz

(dQ/dx - dP/dy) = (1/r) * (du/dz + dv/dr)

The differential dy for the given function y = sin (x^√x^x) is dy = cos(x^√x^x) * (e^(√x^x ln(x)) * (0.5x^x ln(x) + x^(x-1))).

To find the differential dy for the given function y = sin (x^√x^x), we can use the chain rule.

Let u = x^√x^x, and v = sin(u).

First, we find the derivative of u with respect to x:

du/dx = d/dx (x^√x^x)

To differentiate x^√x^x, we can rewrite it as e^(√x^x ln(x)).

Using the chain rule, we have:

du/dx = d/dx (e^(√x^x ln(x)))

= e^(√x^x ln(x)) * d/dx (√x^x ln(x))

= e^(√x^x ln(x)) * (0.5x^x ln(x) + x^x/x)

Simplifying further, we get:

du/dx = e^(√x^x ln(x)) * (0.5x^x ln(x) + x^(x-1))

Next, we find the derivative of v with respect to u:

dv/du = d/dx (sin(u))

= cos(u)

Finally, we can find the differential dy using the chain rule:

dy = dv/du * du/dx

Substituting the derivatives we found:

dy = cos(u) * (e^(√x^x ln(x)) * (0.5x^x ln(x) + x^(x-1)))

Since u = x^√x^x, we can substitute it back into the equation:

dy = cos(x^√x^x) * (e^(√x^x ln(x)) * (0.5x^x ln(x) + x^(x-1)))

Therefore, the differential dy for the given function y = sin (x^√x^x) is dy = cos(x^√x^x) * (e^(√x^x ln(x)) * (0.5x^x ln(x) + x^(x-1))).

To evaluate this integral, we need to use the substitution method;

Let, u = x + 2, du/dx = 1, dx = du

Now, when x = -5, u = -3When x = ∞, u = ∞

Now, we can substitute these values in the integral to get;

∫(s / (x+2))dx = ∫s(u)

since the integral is indefinite, we need to evaluate it at the limits;

∫(-5 to ∞)s(u)du= s(∞) - s(-3)By using the graph, we can interpret the result.

From the graph, it is clear that the function approaches zero as it goes to infinity.

The projection of the vector [1, -2, 2] onto the subspace V spanned by [(1/2)√2, -(1/2)√2, 0] and [(1/2)√2, (1/2)√2, 0] is: Projection = (v . u₁)u₁ + (v . u₂)u₂

where v is the vector to be projected and u₁, u₂ are the basis vectors of V.

The projection calculation involves finding the dot product of the vector v with each basis vector and multiplying it by the corresponding basis vector, then summing these projections.

Let's calculate the projection:

u₁ = [(1/2)√2, -(1/2)√2, 0]

u₂ = [(1/2)√2, (1/2)√2, 0]

v = [1, -2, 2]

Calculating the dot products:

(v . u₁) = 1(1/2)√2 + (-2)(-(1/2)√2) + 2(0) = √2

(v . u₂) = 1(1/2)√2 + (-2)(1/2)√2 + 2(0) = -√2

It is given that the money is deposited daily into a savings account at an annual rate of $15,000. If the account pays 10% compound interest then the balance in the account at the end of 2 years is $13,400,000.

We can use the formula for continuous compound interest:

A = Pe^(rt)

where A is the final amount, P is the initial deposit, r is the annual interest rate (as a decimal), and t is the time in years.

In this case, P is zero since we're starting with an empty account. The annual rate of deposit is $15,000, so the total amount deposited in 2 years is:

15,000 * 365 * 2 = $10,950,000

The interest rate is 10%, so r = 0.1. Plugging in the values, we get:

A = 0 * e^(0.1 * 2) + 10,950,000 * e^(0.1 * 2)

For the vector field F(x,y) = (9x + 10y)j + M(x,y)i is conservative.The function is M(x,y) = 10x + 8y.Answer.

Given information: The vector field F(x,y) = (9x + 10y)j + M(x,y)i is conservative.To find: The function M(x,y)Solution:

The given vector field is conservative, so it can be written as the gradient of a scalar function φ(x,y).

F(x,y)

= (9x + 10y)j + M(x,y)i

Conservative vector field: F(x,y) = ∇φ(x,y)

Let's find the function φ(x,y)

First, we integrate M(x,y) w.r.t x.φ(x,y) = ∫M(x,y)dx + h(y)

We have an unknown function h(y) which can be found by taking partial differentiation of

φ(x,y) w.r.t y.dφ(x,y)/dy

= ∂/∂y [∫M(x,y)dx + h(y)]dφ(x,y)/dy = (∂h(y))/∂y

Comparing it with F(x,y) = (9x + 10y)j + M(x,y)i we have(∂h(y))/∂y = 9x + 10y

On integrating w.r.t y, we get h(y) = 5y2 + 9xy + C

where C is a constant of integration.

The survey results suggest a potential drop in the proportion of adults watching the local TV news between 2010 and 2013, but further analysis is required to draw a definitive conclusion.

In the 2010 survey, out of 50 adults, 40 reported watching the local TV news at least once in the last month, indicating that 80% (40/50) of the adults surveyed were viewers. In the 2013 survey, out of 40 adults, 24 reported watching the local TV news at least once in the last month, suggesting that 60% (24/40) of the adults surveyed were viewers. While there is a decrease in the proportion of adults watching the nightly news based on these survey results, it is essential to consider other factors before concluding that there was a definite drop.

Firstly, the sample sizes in both surveys are relatively small, with 50 adults surveyed in 2010 and 40 in 2013. A larger sample size would provide more reliable results. Additionally, these surveys only capture the behavior of a specific group of adults within a particular geographic region, potentially limiting the generalizability of the findings to the entire adult population.

To find the equation of the line tangent to the curve at the point corresponding to t = 6, we need to evaluate the derivative of the given curve and then use it to find the slope of the tangent line.

We can then use the slope-point form of a line to determine the equation. First, let's differentiate the given curve to find the slope of the tangent line at t = 6. The curve is defined by the equations x = 42 - 4t and y = t^2 + 2t. Taking the derivatives with respect to t, we have dx/dt = -4 and dy/dt = 2t + 2.

Now, we can find the slope of the tangent line at t = 6 by substituting t = 6 into the derivative dy/dt. dy/dt = 2(6) + 2 = 12 + 2 = 14. So, the slope of the tangent line at t = 6 is 14. Next, we need to find the corresponding point on the curve at t = 6. Substituting t = 6 into the equations x = 42 - 4t and y = t^2 + 2t, we get: x = 42 - 4(6) = 42 - 24 = 18, y = 6^2 + 2(6) = 36 + 12 = 48.

Therefore, the point on the curve at t = 6 is (18, 48). Finally, we can use the point-slope form of a line to write the equation of the tangent line. Using the slope (m = 14) and the point (18, 48), we have: y - y1 = m(x - x1),

y - 48 = 14(x - 18). Expanding and rearranging the equation, we find:y - 48 = 14x - 252, y = 14x - 204. Thus, the equation of the line tangent to the curve at the point corresponding to t = 6 is y = 14x - 204.

iv. The derivative of f(x) = 4.25x + 1 with respect to x is 4.25.

v. The derivative of f(x) = 352x² + 22x - 3 with respect to x is 704x + 22.

vi. The derivative of f(x) = log₂(tan(z² + 1)) with respect to x is (2zsec²(z² + 1))/ln(2).

iv. For a linear function f(x) = mx + c,

where m is the slope, the derivative is simply the coefficient of x, which is 4.25 in this case.

v. For a quadratic function f(x) = ax² + bx + c, the derivative is given by 2ax + b.

Here, a = 352 and b = 22,

so the derivative is 704x + 22.

vi. For the function f(x) = log₂(tan(z² + 1)), we can use the chain rule to find its derivative. Let u = z² + 1.

Then f(x) = log₂(tan(u)).

Applying the chain rule, the derivative of f(x) with respect to x is given by (d/dx)(log₂(tan(u))) = (d/du)(log₂(tan(u))) * (du/dx).

The derivative of log₂(tan(u)) with respect to u can be computed using logarithmic differentiation techniques,

resulting in (1/ln(2)) * (1/(tan(u)ln(tan(u)))).

Multiplying this by du/dx, where u = z² + 1,

gives (1/ln(2)) * (1/(tan(z² + 1)ln(tan(z² + 1)))) * (2z).

Simplifying further,

we obtain (2zsec²(z² + 1))/ln(2) as the derivative of f(x) with respect to x.

The derivative of the given expression d(16e^(2x + 1))/dx is 16e^(2x + 1) * 2, which simplifies to 32e^(2x + 1).

To find the derivative of the given expression, d(16e^(2x + 1))/dx, we apply the chain rule. The chain rule is used when we have a composition of functions, where one function is applied to the result of another function. In this case, the outer function is the derivative operator d/dx, and the inner function is 16e^(2x + 1).

The chain rule states that if we have a composition of functions, f(g(x)), then the derivative with respect to x is given by (f'(g(x))) * (g'(x)), where f'(g(x)) represents the derivative of the outer function evaluated at g(x), and g'(x) represents the derivative of the inner function.

Applying the chain rule to our expression, we find that the derivative of 16e^(2x + 1) with respect to x is equal to (16e^(2x + 1)) * (d(2x + 1)/dx). The derivative of (2x + 1) with respect to x is simply 2, since the derivative of x with respect to x is 1 and the derivative of a constant (1 in this case) with respect to x is 0.

Therefore, the derivative of the given expression d(16e^(2x + 1))/dx is 16e^(2x + 1) * 2, which simplifies to 32e^(2x + 1).

To find the y-intercept and x-intercept of the line given by the equation 2x - 3y = -6, we need to determine the points where the line intersects the y-axis (y-intercept) and the x-axis (x-intercept).

To find the y-intercept, we set x = 0 in the equation and solve for y. Plugging in x = 0, we have 2(0) - 3y = -6, which simplifies to -3y = -6. Dividing both sides by -3, we get y = 2. Therefore, the y-intercept is the point (0, 2).

To find the x-intercept, we set y = 0 in the equation and solve for x. Plugging in y = 0, we have 2x - 3(0) = -6, which simplifies to 2x = -6. Dividing both sides by 2, we get x = -3.

The first-order central difference approximation of O(h*) at x = 0.5 is computed using a step size of h = 0.25 for the given function f(x).

To compute the first-order central difference approximation of O(h*) at x = 0.5, we need to evaluate the function f(x) at x = 0.5 + h and x = 0.5 - h, where h is the step size. In this case, h = 0.25. Plugging in the values a = 1, b = 7, c = 2, and d = 4 into the function f(x), we have:

f(0.5 + h) = (1 + 7 + 2)(0.5 + 0.25)^3 + (7 + 2 + 4)(0.5 + 0.25) - (1 * 2 * 4 + 4)
f(0.5 - h) = (1 + 7 + 2)(0.5 - 0.25)^3 + (7 + 2 + 4)(0.5 - 0.25) - (1 * 2 * 4 + 4)

We can then use these values to calculate the first-order central difference approximation of O(h*) by computing the difference between f(0.5 + h) and f(0.5 - h) divided by 2h.

Finally, we can compare this approximation with the analytical solution to assess its accuracy.

When using the Lagrange multiplier method to optimize a function subject to a constraint, focusing on the points where the gradient of the function is perpendicular to the constraint line helps identify potential extremal points that satisfy both the objective function and the constraint simultaneously.

In the context of optimization with a constraint, the Lagrange multiplier method is commonly used. This method introduces Lagrange multipliers to incorporate the constraint into the optimization problem. When considering the points on the line at which the gradient of the function f[x, y, z] (denoted as ∇f[x, y, z]) is perpendicular to the line, we are essentially examining the points where the gradient of the function and the gradient of the constraint (in this case, the line) are parallel.

By introducing a Lagrange multiplier λ, we can form the Lagrangian function L[x, y, z, λ] = f[x, y, z] - λg[x, y, z], where g[x, y, z] represents the equation of the given line. The Lagrange multiplier method seeks to find the values of x, y, z, and λ that simultaneously satisfy the equations:

∇f[x, y, z] - λ∇g[x, y, z] = 0 (1)

g[x, y, z] = 0 (2)

The equation (1) ensures that the gradient of f and the gradient of g are parallel, while equation (2) enforces the constraint that the variables lie on the given line.

At the points where ∇f[x, y, z] is perpendicular to the line, the dot product between ∇f[x, y, z] and the tangent vector of the line is zero. This means that ∇f[x, y, z] and the tangent vector are orthogonal, and thus the gradient of f is parallel to the normal vector of the line.

In the Lagrange multiplier method, finding the points where ∇f[x, y, z] is perpendicular to the line becomes crucial because it helps identify potential extremal points that satisfy both the objective function and the constraint simultaneously.

The general solution of the differential equation is y = -1/((1/3)x^3 + C1), where C1 is the constant of integration. The general solution of the differential equation is y = 5/2 + C2 * e^(-x^2), where C2 is the constant of integration.

1. For the general solution of the differential equation dy = y^2x^2 dx, we'll separate the variables and integrate both sides:

dy/y^2 = x^2 dx

Integrating both sides:

∫(dy/y^2) = ∫(x^2 dx)

To integrate the left side, we can use the power rule of integration:

-1/y = (1/3)x^3 + C1

Multiplying both sides by -1 and rearranging:

y = -1/((1/3)x^3 + C1)

So the general solution of the differential equation is y = -1/((1/3)x^3 + C1), where C1 is the constant of integration.

2.The differential equation is dy/dx + 2xy = 5x.

This is a linear first-order ordinary differential equation. To solve it, we'll use an integrating factor.

The integrating factor (IF) is given by the exponential of the integral of the coefficient of y, which in this case is 2x:

IF = e^(∫2x dx) = e^(x^2)

Multiplying both sides of the differential equation by the integrating factor:

e^(x^2) * dy/dx + 2xye^(x^2) = 5xe^(x^2)

The left side can be simplified using the product rule of differentiation:

(d/dx)[y * e^(x^2)] = 5xe^(x^2)

Integrating both sides:

∫(d/dx)[y * e^(x^2)] dx = ∫(5xe^(x^2) dx)

Integrating the left side gives:

y * e^(x^2) = 5/2 * e^(x^2) + C2

Dividing both sides by e^(x^2):

y = 5/2 + C2 * e^(-x^2)

So the general solution of the differential equation is y = 5/2 + C2 * e^(-x^2), where C2 is the constant of integration.

The given function is y = -3x^2 + 5x + 3. To find the relative maxima and minima, we can use calculus. Plugging this value back into the original function, we find y = -3(5/6)^2 + 5(5/6) + 3 = 25/12. So the relative minimum is at (5/6, 25/12).

To determine the points of inflection, we need to find the second derivative. Taking the derivative of y', we get y'' = -6. Setting y'' equal to zero gives no solutions, which means there are no points of inflection in this case.  To find the relative maxima and minima, we can use calculus. Taking the derivative of the function, we get y' = -6x + 5. To find the critical points, we set y' equal to zero and solve for x. In this case, -6x + 5 = 0 gives x = 5/6.

In summary, the function has a relative minimum at (5/6, 25/12), and there are no relative maxima or points of inflection.

To find the relative maxima and minima, we used the first derivative test. By setting the derivative equal to zero and solving for x, we found the critical point (x = 5/6). We then plugged this value into the original function to obtain the corresponding y-value. This gave us the relative minimum at (5/6, 25/12). To determine the points of inflection, we looked at the second derivative. However, since the second derivative was constant (-6), there were no solutions to y'' = 0, indicating no points of inflection. The graph of the function would be a downward-facing parabola with the vertex at the relative minimum point and no points of inflection.
