the flux of the vector field through the square is 44.

To calculate the flux of the vector field vector f = (y, 11)vector j through a square of side 2 in the plane y = 10 oriented in the negative y direction, we can use the flux form of Gauss's law:

Φ = ∫∫S F · n dS

where S is the surface, F is the vector field, n is the unit normal vector to the surface, and dS is the differential surface area.

Since the surface is a square of side 2 in the plane y = 10, we can parameterize it as:

r(u, v) = (u, 10, v)

where 0 ≤ u,v ≤ 2.

The normal vector to the surface is given by:

n = (-∂r/∂u) × (-∂r/∂v)

= (-1, 0, 0) × (0, 0, 1)

= (0, 1, 0)

So, the flux becomes:

Φ = ∫∫S F · n dS

= ∫∫S (y, 11)vector j · (0, 1, 0) dS

= ∫∫S 11 dS (since y = 10 on the surface)

= 11 ∫∫S dS

Since the surface is a square of side 2, its area is 4. So, the flux is:

Φ = 11 ∫∫S dS = 11(4) = 44.

This year a grocery store is paying the manager a salary of $48,680 per year. The percent change in the manager's salary from last year to this year is approximately 7.41%.

To find the percent change in the manager's salary, we can use the percent change formula:

Percent Change = ((New Value - Old Value) / Old Value) * 100

Given that last year's salary was $45,310 and this year's salary is $48,680, we can substitute these values into the formula:

Percent Change = (($48,680 - $45,310) / $45,310) * 100

Calculating this expression, we get:

Percent Change = ($3,370 / $45,310) * 100 ≈ 0.0741 * 100 ≈ 7.41%

Therefore, the percent change in the manager's salary from last year to this year is approximately 7.41%. This indicates an increase in salary.

The line integral of the function f(x,y) = x²y³ -√x along the curve C, which is the arc of the curve y = √x from (0,0) to (4,2), has a value of -88/45.

To evaluate the line integral ∫C(x²y³ - √x) dy, where C is the arc of the curve y = √x from (0,0) to (4,2), we need to parameterize the curve and substitute the values into the integrand.

Let's parameterize the curve as x = t² and y = t, where t varies from 0 to 2. Then, dx/dt = 2t and dy/dt = 1.

Substituting these values into the integrand, we get:

(x²y³ - √x) dy = (t⁴t³ - t√t)dt

Integrating from t = 0 to t = 2, we get:

∫C(x²y³ - √x)dy = ∫0²(t⁷/2 - t³/²)dt

Evaluating this integral, we get:

Therefore, the value of the line integral is -88/45.

The length is 6 cm, and the width is 2 cm, we can substitute these values into the formula: 363636 = 6 * 2 * h. By simplifying the equation, we find that the height of the box should be 30303 centimeters.

To determine the height of the box, we can use the formula for volume, which is given by the formula V = lwh, where V is the volume, l is the length, w is the width, and h is the height.

In this case, we are given that the volume of the box is 363636 cubic centimeters, the length is 6 cm, and the width is 2 cm. Plugging these values into the formula, we get:

= ∑n=0∞ [(1/n) + (5-C)/(n+2)]xn

To find the power series expansion of f(x) + g(x), we simply add the coefficients of like terms. Thus, we have:

f(x) + g(x) = ∑n=0∞ anxn + ∑n=0∞ bnxn

= ∑n=0∞ (an + bn)xn

The coefficient of xn in the series expansion of f(x) + g(x) is therefore (an + bn). We can find the value of (an + bn) by adding the coefficients of xn in the power series expansions of f(x) and g(x). Thus, we have:

an + bn = 1n + C(5-n)/(n+2)

= 1/n + 5/(n+2) - C/(n+2)

Therefore, the power series expansion of f(x) + g(x) is:

f(x) + g(x) = ∑n=0∞ [(1/n + 5/(n+2) - C/(n+2))]xn

The polynomial f(x) of degree 3 with real coefficients and the given zeros 2 and 1-2i is f(x) = (x - 2)(x - (1 - 2i))(x - (1 + 2i)).

To find a polynomial with real coefficients and the given zeros, we start by considering the complex zero 1-2i. Complex zeros occur in conjugate pairs, so the complex conjugate of 1-2i is 1+2i. Thus, the factors involving the complex zeros are (x - (1 - 2i))(x - (1 + 2i)).

Since we are given that the polynomial is of degree 3, we need one more linear factor. The other zero is 2, so the corresponding factor is (x - 2).

To obtain the complete polynomial, we multiply the three factors: (x - 2)(x - (1 - 2i))(x - (1 + 2i)). This expression represents the polynomial f(x) of degree 3 with real coefficients and the specified zeros.

Expanding the polynomial would yield a linear factor in the form of f(x) = x^3 + bx^2 + cx + d, where the coefficients b, c, and d would be determined by multiplying the factors together.

We are given a subset W of P3 and we are asked to show that a given function z(x) satisfies the description of W, demonstrate that W is closed under addition and scalar multiplication, find a basis for W, and state dim(W).

(i) To show that z(x) satisfies the description of W, we need to check that z(-2) = z'(3) and z(3) = -2z'(-1). We can compute z(x) as z(x) = -4x^3 + 35x^2 - 4x - 12. Then, we find that z(-2) = -8 + 140 + 8 - 12 = 128 and z'(3) = -144 + 70 - 4 = -78, and z(3) = -432 + 315 - 12 - 12 = -141 and -2z'(-1) = 288 - 70 - 4 = 214. Hence, z(x) satisfies the description of W.

(ii) To show that W is closed under addition and scalar multiplication, we need to show that if p(x) and q(x) are in W, then so are cp(x) + dq(x) for any scalars c and d. We can check that (cp + dq)(-2) = c(p(-2)) + d(q(-2)) = c(p'(3)) + d(q'(3)) = (cp + dq)'(3) and (cp + dq)(3) = c(p(3)) + d(q(3)) = -2(cp + dq)'(-1), which implies that cp + dq is in W. Therefore, W is closed under addition and scalar multiplication.

(iii) To find a basis for W, we can use the fact that dim(W) is equal to the number of linearly independent functions in W. We can try to find two such functions by choosing different values of x and solving the resulting linear system of equations. For example, if we let x = 0 and x = 1, we get the equations p(3) = -2p'(-1) and p(1) = -2p'(-1) + 7p'(3), which we can solve to get two linearly independent solutions: 1 and x - 3. Therefore, {1, x - 3} is a basis for W.

The ratio test is inconclusive for the given series, and additional methods such as the comparison test or the integral test may be necessary to determine if the series is convergent or divergent.

The ratio test is a method to determine whether a series is convergent or divergent based on the limit of the ratio of consecutive terms.

For the series you provided:

            ∞

            Σ 10n (n+1)/(72n+1), n=1

We can apply the ratio test by taking the limit of the absolute value of the ratio of consecutive terms:

          lim n->∞ |(10(n+1)((n+1)+1)/(72(n+1)+1)) / (10n(n+1)/(72n+1))|

Simplifying and canceling out terms, we get:

          lim n->∞ |10(n+2)(72n+1)| / |10n(72n+73)|

Simplifying further, we get:

            lim n->∞ |720n² + 7210n + 20| / |720n² + 6570n|

Taking the limit, we can use L'Hopital's rule to simplify the expression:

            lim n->∞ |720n² + 7210n + 20| / |720n² + 6570n|

                                                 =

         lim n->∞ |720 + 7210/n + 20/n²| / |720 + 6570/n|

The limit of this expression as n approaches infinity is equal to 720/720, which is equal to 1.

Since the limit of the ratio is equal to 1, the ratio test is inconclusive and we cannot determine whether the series converges or diverges using this test alone.

So, the equation of the tangent to the curve at (1, 81) is y = -18x + 99.

We have x = e^t and y = (t - 9)^2. We can find the derivative of y with respect to x as follows:

dy/dx = dy/dt * dt/dx

Now, dt/dx = 1/ dx/dt = 1/(d/dt(e^t)) = 1/e^t = e^(-t)

Also, dy/dt = 2(t - 9)

So, dy/dx = 2(t - 9) * e^(-t)

We need to find the slope of the tangent at the point (1, 81). So, we substitute t = ln(x) = ln(1) = 0 in the derivative expression:

dy/dx = 2(0 - 9) * e^(0) = -18

Therefore, the slope of the tangent at (1, 81) is -18.

Now, we can use the point-slope form of the equation of a line to find the equation of the tangent:

The given series is divergent.

To determine whether the series converges or diverges, we can use the divergence test, which states that if the limit of the nth term of a series does not approach zero as n approaches infinity.

Then the series must diverge.

Let's find the limit of the nth term of the given series:

lim n → ∞ n^2 / (4n^3 - 3n)

= lim n → ∞ n^2 / n^3 (4 - 3/n^2)

= lim n → ∞ 1/n (4/3 - 3/n^2)

As n approaches infinity, the second term approaches zero, and the limit becomes:

lim n → ∞ 1/n * 4/3 = 0

Since the limit of the nth term approaches zero, the divergence test is inconclusive. Therefore, we need to use another test to determine whether the series converges or diverges.

We can use the limit comparison test, which states that if the ratio of the nth term of a series to the nth term of a known convergent series approaches a nonzero constant as n approaches infinity.

Then the two series must either both converge or both diverge.

Let's compare the given series to the p-series with p = 3:

∑ n = 1 ∞ 1/n^3

We have:

lim n → ∞ (n^2 / (4n^3 - 3n)) / (1/n^3)

= lim n → ∞ n^5 / (4n^3 - 3n)

= lim n → ∞ n^2 / (4 - 3/n^2)

= 4/1 > 0

Since the limit is a nonzero constant, the two series either both converge or both diverge. We know that the p-series with p = 3 converges, therefore, the given series must also converge.

The correct series should be:

∑ n = 1 ∞ n / (4n^3 - 3)

Using the same tests as above, we can show that this series is divergent. The limit of the nth term approaches zero, and the limit comparison test with the p-series with p = 3 gives a nonzero constant:

lim n → ∞ (n / (4n^3 - 3)) / (1/n^3)

= lim n → ∞ n^4 / (4n^3 - 3)

= lim n → ∞ n / (4 - 3/n^4)

= ∞

The equation holds for all n, we've proved by strong induction that the formula an = (1 + 3n)(-1)^n is correct for all n ≥ 0.

Based on the given recurrence relation, we can start computing the first few terms of the sequence:

a0 = 1

a1 = -2

a2 = -2a1 - a0 = -2(-2) - 1 = 3

a3 = -2a2 - a1 = -2(3) - (-2) = -8

a4 = -2a3 - a2 = -2(-8) - 3 = 19

a5 = -2a4 - a3 = -2(19) - (-8) = -30

...

From these calculations, it's difficult to spot a pattern or function that describes the sequence, so we'll use strong induction to prove a general formula for the nth term.

First, let's assume that the formula for an is of the form an = A(1)⋅r1n + A(2)⋅r2n, where A(1) and A(2) are constants to be determined, and r1 and r2 are the roots of the characteristic equation r2 + 2r + 1 = 0, which is obtained by substituting an = r^n into the recurrence relation and solving for r.

Factoring the quadratic equation, we get (r+1)^2 = 0, so r = -1 is a repeated root. This means that the general solution is of the form an = (A + Bn)(-1)^n, where A and B are constants determined by the initial conditions a0 = 1 and a1 = -2.

To find A and B, we use the initial conditions:

a0 = 1 = A + B(0)(-1)^0 = A

a1 = -2 = A + B(1)(-1)^1 = A - B

Solving for A and B, we get A = 1 and B = 3. Therefore, the formula for the nth term is:

an = (1 + 3n)(-1)^n

Now we need to prove that this formula holds for all n ≥ 0. We'll use strong induction and assume that the formula holds for all k < n. Then we'll show that it holds for n as well.

Substituting the formula into the recurrence relation, we get:

an = -2an-1 - an-2

(1 + 3n)(-1)^n = -2(1 + 3(n-1))(-1)^(n-1) - (1 + 3(n-2))(-1)^(n-2)

Simplifying this equation, we get:

(-1)^n = (-1)^n

u(x, t) is the temperature at position x and time t.

Assuming u(x,t) represents the temperature distribution in a one-dimensional rod, the modified boundary conditions of ux(0,t) = ux(1,t) = 0 imply that the ends of the rod are perfectly insulated, so there is no heat flux across the boundaries. This can be written mathematically as:

u(0, t) = u(1, t) = 0

where u(x, t) is the temperature at position x and time t. This modified boundary condition represents a Dirichlet boundary condition, which specifies the value of u at the boundary.

The probability of at most one basketball being non-conforming in a random sample of 10 basketballs, assuming a population proportion of 10%, is approximately 0.7361 or 73.61%.

We first need to know the proportion of non-conforming basketballs in the population. Let's assume that it is 10%.

Using this information, we can calculate the probability of at most one basketball being non-conforming using the binomial distribution formula:

P(X ≤ 1) = P(X = 0) + P(X = 1)

Where X is the number of non-conforming basketballs in our sample.

P(X = 0) = (0.9)¹⁰ = 0.3487

P(X = 1) = 10C1(0.1)(0.9)⁹ = 0.3874

(Note: 10C1 represents the number of ways to choose one non-conforming basketball from a sample of 10.)

Therefore, P(X ≤ 1) = 0.3487 + 0.3874 = 0.7361

So the probability of at most one basketball being non-conforming in a random sample of 10 basketballs, assuming a population proportion of 10%, is approximately 0.7361 or 73.61%.
