A. The equation 7x(9x + 16) = 14 - (-x + 19) has solutions x = (-111 + √(11061)) / 126 and x = (-111 - √(11061)) / 126.

B. The equation ²x + 1 = 2x - 1² is inconsistent and has no real solutions.

To solve the given equations for x, we will simplify each equation step by step until we isolate the variable x.

A. 7x(9x + 16) = 14 - (-x + 19)

First, distribute the 7x on the left side:

63x^2 + 112x = 14 - (-x + 19)

Simplify the right side:

63x^2 + 112x = 14 + x - 19

63x^2 + 112x = x - 5

Rearrange the equation to bring all terms to one side:

63x^2 + 112x - x + 5 = 0

Combine like terms:

63x^2 + 111x + 5 = 0

Unfortunately, this quadratic equation cannot be factored easily. We can use the quadratic formula to find the solutions for x:

x = (-b ± √(b^2 - 4ac)) / (2a)

In this case, a = 63, b = 111, and c = 5.

Substituting the values into the quadratic formula:

x = (-111 ± √(111^2 - 4 * 63 * 5)) / (2 * 63)

Calculating further, we find:

x = (-111 ± √(12321 - 1260)) / 126

x = (-111 ± √(11061)) / 126

Since the equation cannot be simplified further, the solutions for x are:

x = (-111 + √(11061)) / 126

x = (-111 - √(11061)) / 126

B. ²x + 1 = 2x - 1²

First, simplify the equation:

x^2 + 1 = 2x - 1

Rearrange the equation:

x^2 - 2x + 1 + 1 = 0

Combine like terms:

x^2 - 2x + 2 = 0

Again, this quadratic equation does not factor easily. We will use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

In this case, a = 1, b = -2, and c = 2.

Substituting the values into the quadratic formula:

x = (-(-2) ± √((-2)^2 - 4 * 1 * 2)) / (2 * 1)

Simplifying further:

x = (2 ± √(4 - 8)) / 2

x = (2 ± √(-4)) / 2

Since we have a square root of a negative number, the equation has no real solutions. The solutions involve imaginary numbers. Therefore, the equation is inconsistent.

= 2.98 ≈ 3ψ(50,7) = exp(√(ln 50 ln 7) )ψ(50,7)

= exp(√(3.912 - 2.302) )ψ(50,7) = exp(1.095)

= 3.00 ≈ 3ψ(100,5) = exp(√(ln 100 ln 5) )ψ(100,5)

= exp(√(4.605 - 1.609) )ψ(100,5) = exp(1.991)

= 7.32 ≈ 7

Therefore,ψ(25,3) = 1ψ(35,5) = 3ψ(50,7) = 3ψ(100,5) = 7

The given equation is y = 4^(x2–2x+5).To find the tangent line to the curve at x = 4, differentiate the given function with respect to x and find the slope of the tangent at x = 4.

Given function is y = 4^(x2–2x+5). In order to find the equation of the tangent line to the curve at x = 4, we need to differentiate the given function with respect to x and find the slope of the tangent at x = 4. Then we use the point-slope form of the equation to find the equation of the tangent line.The process of finding the equation of the tangent line to the curve is by first differentiating the given function.

We differentiate the given function as follows:d/dx(y) = d/dx[4^(x2–2x+5)] => d/dx(y) = 4^(x2–2x+5) * d/dx[x2–2x+5]

=> d/dx(y) = 4^(x2–2x+5) * [2x - 2]When x = 4,d/dx(y) = 4^(42–2*4+5) * [2*4 - 2]

=> d/dx(y) = 4^(5) * [6]

=> d/dx(y) = 6 * 1024

The slope of the tangent at x = 4 is: m = 6 * 1024

The point is: (4, y)We substitute the values in the point-slope form of the equation of the line:y - y1 = m(x - x1)

=> y - y1 = m(x - 4)

=> y - y1 = 6 * 1024 (x - 4)

Where x1 = 4, y1 = 4^(42–2*4+5)

=> y1 = 4^(5)

=> y1 = 1024

Therefore, the equation of the tangent line to y = 4^(x2–2x+5) at x = 4 is y - 1024 = 6 * 1024 (x - 4).

Therefore, we can conclude that the equation of the tangent line to y = 4^(x2–2x+5) at x = 4 is y - 1024 = 6 * 1024 (x - 4).

(a) The velocity of the rocket 6 seconds after being fired is 280 feet/sec.(b) The correct answer is: Speeding up in (0, 0.5) U (2, [infinity]) and slowing down in (0.5, 2).

(a) To find the velocity of the rocket 6 seconds after being fired, we need to find the derivative of the position function s(t) with respect to time t.

Given: s(t) = -18t² + 496t

Velocity is the derivative of position, so we differentiate s(t) with respect to t:

v(t) = s'(t) = d/dt (-18t² + 496t)

Using the power rule of differentiation, we differentiate each term separately:

v(t) = -36t + 496

Now, substitute t = 6 into the velocity function to find the velocity of the rocket 6 seconds after being fired:

v(6) = -36(6) + 496

v(6) = -216 + 496

v(6) = 280 feet/sec

Therefore, the velocity of the rocket 6 seconds after being fired is 280 feet/sec.

(b) To find the acceleration of the rocket 6 seconds after being fired, we need to find the derivative of the velocity function v(t) with respect to time t.

Given: v(t) = -36t + 496

Acceleration is the derivative of velocity, so we differentiate v(t) with respect to t:

a(t) = v'(t) = d/dt (-36t + 496)

Using the power rule of differentiation, we differentiate each term separately:

a(t) = -36

The acceleration is constant and does not depend on time. Therefore, the acceleration of the rocket 6 seconds after being fired is -36 feet/sec².

For the second part of the question:

Given: s(t) = 4t³ – 6t² – 24t + 3

To determine the time intervals when the object is slowing down or speeding up, we need to analyze the sign of the velocity and acceleration functions.

First, let's find the velocity function by taking the derivative of s(t):

v(t) = s'(t) = d/dt (4t³ – 6t² – 24t + 3)

Using the power rule of differentiation, we differentiate each term separately:

v(t) = 12t² - 12t - 24

Next, let's find the acceleration function by taking the derivative of v(t):

a(t) = v'(t) = d/dt (12t² - 12t - 24)

Using the power rule of differentiation, we differentiate each term separately:

a(t) = 24t - 12

To determine when the object is slowing down or speeding up, we need to examine the signs of both velocity and acceleration.

For speeding up, both velocity and acceleration should have the same sign.

For slowing down, velocity and acceleration should have opposite signs.

Let's analyze the signs of velocity and acceleration in different intervals:

Interval (0, 0.5):

In this interval, both velocity and acceleration are positive.

The object is speeding up.

Interval (0.5, 2):

In this interval, velocity is positive and acceleration is negative.

The object is slowing down.

Interval (2, [infinity]):

In this interval, both velocity and acceleration are positive.

The object is speeding up.

Therefore, the correct answer is: Speeding up in (0, 0.5) U (2, [infinity]) and slowing down in (0.5, 2).

The approximate value of the definite integral of the function f(x) = x.ex for the interval [1, 3] using Simpson's Rule is 13e + 86e2 + 43e3.

Simpson's Rule is a numerical method used to estimate the definite integral of a function f(x) between two limits a and b. It divides the area under the curve into smaller segments by approximating the curve using parabolic arcs. Then, it sums the areas of all the parabolic segments to obtain an approximation of the integral value.Integration result for f(x) = x.ex for the interval [1, 3]:

Let's use Simpson's Rule to estimate the value of the definite integral of the function f(x) = x.ex for the interval [1, 3]. The formula for Simpson's Rule is given by:

∫abf(x)dx ≈ Δx3[ f(a)+4f(a+b/2)+f(b) ]

where Δx = (b-a)/2 = (3-1)/2 = 1.

The limits of integration are a = 1 and b = 3.

Therefore,Δx = 1 and x0 = 1, x1 = 2, and x2 = 3 are the three points of division of the interval [1, 3].

We now need to find the values of f(x) at these points.

f(x0) = f(1)

= 1.

e1 = e,

f(x1) = f(2)

= 2.

e2 = 2e2, and

f(x2) = f(3)

= 3.

e3 = 3e3.

Substituting these values in Simpson's Rule, we get:

∫13x.exdx ≈ 13[ f(1)+4f(3/2)+f(3) ]

= 13[ e+4(2e2)+3e3 ]

= 13e + 86e2 + 43e3

The approximate value of the definite integral of the function f(x) = x.ex for the interval [1, 3] using Simpson's Rule is 13e + 86e2 + 43e3.

The general solution of the given differential equation is:

(x^2 + y^2) = C, where C is an arbitrary constant.

To solve the given differential equation, we can start by rearranging the terms:

(x+y)y' = 9x - y

Expanding the left-hand side using the product rule, we get:

xy' + y^2 = 9x - y

Next, let's isolate the terms involving y on one side:

y^2 + y = 9x - xy'

Now, we can observe that the left-hand side resembles the derivative of (y^2/2). So, let's take the derivative of both sides with respect to x:

d/dx (y^2/2 + y) = d/dx (9x - xy')

Using the chain rule, the right-hand side can be simplified to:

d/dx (9x - xy') = 9 - y' - xy''

Substituting this back into the equation, we have:

d/dx (y^2/2 + y) = 9 - y' - xy''

Integrating both sides with respect to x, we obtain:

y^2/2 + y = 9x - y'x + g(y),

where g(y) is the constant of integration.

Now, let's rearrange the equation to isolate y':

y'x - y = 9x - y^2/2 - g(y)

Separating the variables and integrating, we get:

∫(1/y^2 - 1/y) dy = ∫(9 - g(y)) dx

Simplifying the left-hand side, we have:

∫(1/y^2 - 1/y) dy = ∫(1/y) dy - ∫(1/y^2) dy

Integrating both sides, we obtain:

-ln|y| + 1/y = 9x - g(y) + h(x),

where h(x) is the constant of integration.

Combining the terms involving y and rearranging, we have:

-y - ln|y| = 9x + h(x) - g(y)

Finally, we can express the general solution in the implicit form:

(x^2 + y^2) = C,

where C = -g(y) + h(x) is the arbitrary constant combining the integration constants.

In unit-vector notation, this magnetic field should have a value of (-1.805, 0, 0) Tesla.

The uniform magnetic field required to make an electron travel in a straight line through the gap between the two parallel plates is given by the equation B = (V1 - V2)/dv.

Plugging in the known values for V1, V2, and d gives us a result of B = 1.805 T. Since the velocity vector of the electron is perpendicular to the electric field between the plates, the magnetic field should be pointing along the direction of the velocity vector.

Therefore, the magnetic field that should be present between the two plates should point along the negative direction of the velocity vector in order to cause the electron to travel in a straight line.

In unit-vector notation, this magnetic field should have a value of (-1.805, 0, 0) Tesla.

The two curves r = 1 + 2 cos θ and r = 2 intersect at two points. The values of θ where the curves intersect can be found by setting the equations equal to each other and solving for θ.

To find the points of intersection, we set the two equations equal to each other:

1 + 2 cos θ = 2

Simplifying the equation, we get:

2 cos θ = 1

Dividing both sides by 2, we have:

cos θ = 1/2

From trigonometric values, we know that cos θ = 1/2 at θ = π/3 and θ = 5π/3.

Therefore, the curves r = 1 + 2 cos θ and r = 2 intersect at two points. The angles at which the curves intersect are θ = π/3 and θ = 5π/3. These points correspond to the values of θ where the curves overlap. The exact coordinates of the points of intersection can be found by substituting these values of θ into either of the original equations.

The equations of motion for the given scenarios are: (a) x(t) = -sin(ωt) (b) x(t) = -sin(ωt) + C*cos(ωt). To determine the equations of motion for the given scenarios, we can use Newton's second law of motion.

Let's denote the position of the mass as "x(t)" and its velocity as "v(t)".  To determine the equations of motion for the given scenarios, we can use Newton's second law of motion. Let's denote the position of the mass as "x(t)" and its velocity as "v(t)". The restoring force exerted by the spring is given by Hooke's law as -kx, where "k" is the spring constant. The damping force is numerically equal to 12 times the instantaneous velocity and is given by -12v.

The equation of motion is given by:

m(d²x/dt²) = -kx - 12v

For part (a), where the mass is initially released from rest from a point 1 meter below the equilibrium position, we have the initial conditions:

x(0) = -1

v(0) = 0

To solve this second-order linear differential equation, we can first consider the homogeneous equation (without the damping force) and find its solution. The equation becomes:

m(d²x/dt²) + kx = 0

The solution to this equation is of the form x(t) = Acos(ωt) + Bsin(ωt), where A and B are constants and ω = sqrt(k/m) is the angular frequency.

Next, we need to find the particular solution that satisfies the given initial conditions. Since the mass is initially at rest (v(0) = 0), the particular solution will only involve the cosine term, and the constant A will be zero. The equation becomes:

x(t) = B*sin(ωt)

Applying the initial condition x(0) = -1, we find B = -1.

Therefore, the equation of motion for part (a) is:

x(t) = -sin(ωt)

For part (b), where the mass is initially released from a point 1 meter below the equilibrium position with an upward velocity of 11 m/s, we have the initial conditions:

x(0) = -1

v(0) = 11

Using a similar approach as in part (a), we can find the particular solution that satisfies these initial conditions. The equation of motion for part (b) will be:

x(t) = -sin(ωt) + C*cos(ωt)

where C is a constant determined by the initial velocity v(0) = 11.

In summary, the equations of motion for the given scenarios are:

(a) x(t) = -sin(ωt)

(b) x(t) = -sin(ωt) + C*cos(ωt)

We will use Stokes' Theorem to evaluate the curl of the vector field F = < -yz, xz, xy > over the surface S, which is the part of the paraboloid z = 8 - x² - y² that lies above the plane z = 7, and is oriented upwards.

Stokes' Theorem states that the flux of the curl of a vector field across a surface is equal to the circulation of the vector field around the boundary curve of the surface.

To apply Stokes' Theorem, we need to calculate the curl of F. Let's compute it first:

curl F = ∇ x F

       = ∇ x < -yz, xz, xy >

       = det | i    j    k   |

             | ∂/∂x ∂/∂y ∂/∂z |

             | -yz   xz   xy  |

       = (∂/∂y (xy) - ∂/∂z (xz)) i - (∂/∂x (xy) - ∂/∂z (-yz)) j + (∂/∂x (xz) - ∂/∂y (-yz)) k

       = (x - z) i + (y + z) j + (0) k

       = (x - z) i + (y + z) j

Next, we need to find the boundary curve of the surface S, which is the intersection between the paraboloid and the plane z = 7. To find the boundary curve, we set z = 7 in the equation of the paraboloid:

7 = 8 - x² - y²

x² + y² = 1

The boundary curve is a circle of radius 1 centered at the origin. Let's parameterize it as r(t) = < cos(t), sin(t), 7 >, where 0 ≤ t ≤ 2π.

Now, we calculate the dot product of curl F and the outward unit normal vector to the surface. Since the surface is oriented upwards, the outward unit normal vector is simply < 0, 0, 1 >.

dot(curl F, n) = dot((x - z) i + (y + z) j, < 0, 0, 1 >)

              = 0 + 0 + (y + z)

              = y + z

To evaluate the integral using Stokes' Theorem, we need to calculate the circulation of F around the boundary curve, which is given by:

∮(curl F) · ds = ∫(y + z) ds

Using the parameterization r(t) = < cos(t), sin(t), 7 >, we can express ds as ds = |r'(t)| dt:

ds = |<-sin(t), cos(t), 0>| dt

  = √(sin²(t) + cos²(t)) dt

  = dt

Therefore, the circulation of F around the boundary curve is:

∮(curl F) · ds = ∫(y + z) ds

              = ∫(sin(t) + 7) dt

              = ∫sin(t) dt + 7∫dt

              = -cos(t) + 7t

To evaluate this integral, we substitute the limits of the parameter t, which are 0 and 2π:

∮(curl F) · ds = [-cos(t) + 7t] evaluated from 0 to 2π

              = [-cos(2π) + 7(2π)] - [-cos(0) + 7

(0)]

              = [-1 + 14π] - [-1 + 0]

              = 14π

Therefore, using Stokes' Theorem, the evaluated integral is 14π.

The characteristic equation of the network is in the form s² + qs + r. After simplifying the given equation, the value of "q" in the characteristic equation is 14.

To simplify the given equation to the characteristic equation, let's break it down step by step. The equation is as follows:

ad²u₂(0) + b[d(0)] + b[dy(0)] + v,₁(1) = 0

The term ad²u₂(0) represents the second derivative of a function u₂(0) with respect to time t. Since there are no additional terms involving this function, we can disregard it for now.

Next, we have b[d(0)], which is the product of b and the derivative of a function d(0) with respect to time. Similarly, we have b[dy(0)], which is the product of b and the derivative of a function y(0) with respect to time.

Finally, we have v,₁(1), which represents the first derivative of a function v(1) with respect to time. This term directly contributes to the characteristic equation.

Combining all these terms, the simplified characteristic equation becomes:

b[d(0)] + b[dy(0)] + v,₁(1) = 0

Since we are interested in the value of "q" in the characteristic equation of the form s² + qs + r, we can see that "q" is the coefficient of the s term. In this case, "q" is twice the coefficient of the term v,₁(1). Given that b = 10, the value of "q" is 2 * 10 = 20.

The 2-norm of the matrix [tex](VHA)^{-1[/tex] is 2.

To find the 2-norm of the matrix [tex](VHA)^-{1[/tex], where A = UΣVH, we need to perform the following steps:

Compute the singular value decomposition (SVD) of A:

A = UΣVH

Find the inverse of the matrix (VHA):

[tex](VHA)^{-1} = (VU\sum VH)^{-1} = VH^{-1}U^{-1}(\sum^{-1})[/tex]

Calculate the 2-norm of (VHA)^-1:

||[tex](VHA)^{-1[/tex]||₂ = ||[tex]VH^{-1}U^{-1}(\sum^-1)[/tex]||₂

Given the SVD of A as A = UVH, where

U = [-1/√2 0 1; 1/√2 0 0; -1/√2 0 -1/√2]

Σ = [3; 2; 0]

VH = [0 2 0]

Let's proceed with the calculations:

Step 1: Compute the inverse of VH:

[tex]VH^{-1} = (VH)^{-1[/tex]

[tex]= H^{-1}V^{-1[/tex]

= VH

= [0 2 0]

Step 2: Compute the inverse of U:

[tex]U^{-1}[/tex] = [-1/√2 0 -1/√2; 0 0 0; 1/√2 0 -1/√2]

Step 3: Compute the inverse of Σ:

Σ^-1 = [1/3; 1/2; Undefined]

Since Σ has a zero value in the third position, the inverse of Σ has an undefined value in the third position.

Step 4: Calculate the 2-norm of [tex](VHA)^{-1[/tex]:

||[tex](VHA)^{-1[/tex]||₂ = ||[tex]VH^{-1}U^{-1}(\sum^{-1})[/tex]||₂

Plugging in the values, we have:

||(VHA)^-1||₂ = ||[0 2 0][-1/√2 0 -1/√2; 0 0 0; 1/√2 0 -1/√2][1/3; 1/2; Undefined]||₂

Simplifying the matrix multiplication, we get:

||(VHA)^-1||₂ = ||[0 0 0; 0 0 0; 0 2 0]||₂

Calculating the 2-norm of the resulting matrix, we find:

||(VHA)^-1||₂ = 2

Therefore, the 2-norm of the matrix (VHA)^-1 is 2.

To find the volume of the solid enclosed by the cone z = √(x² + y²) between the planes z = 1 and z = 2, we can use spherical coordinates. The volume can be computed by integrating over the appropriate region in spherical coordinates.

In spherical coordinates, the cone z = √(x² + y²) can be expressed as ρ = z, where ρ represents the radial distance, φ represents the polar angle, and θ represents the azimuthal angle.

To find the limits of integration, we need to determine the range of ρ, φ, and θ that encloses the solid between the planes z = 1 and z = 2. Since z ranges from 1 to 2, we have 1 ≤ ρ ≤ 2. The polar angle φ ranges from 0 to 2π, covering the entire azimuthal angle. Thus, 0 ≤ φ ≤ 2π.

The volume element in spherical coordinates is given by dV = ρ² sin φ dρ dφ dθ. We can integrate this volume element over the given limits to calculate the volume:

V = ∫∫∫ dV = ∫₀²∫₀²π ρ² sin φ dρ dφ dθ

Evaluating this triple integral will yield the volume of the solid enclosed by the cone between the planes z = 1 and z = 2 in spherical coordinates.

The formula for the radius of convergence, denoted by $R, is $R = lim n to infinity frac M |n + 1 = 0 $. As a result, the radius of convergence is equal to zero, and the interval of convergence is equal to [3,3]. The following is the given series:$$(-1) (x - 3) (n + 1)$$

First, in order to determine the radius of convergence, let's take the absolute value of the series:$$\begin{aligned} \left|(-1) (x - 3) (n + 1)\right| &\leq M \\ |x - 3| &\leq \frac{M}{|n + 1|} \end{aligned}$$

For $x = 3$, we have$$\begin{aligned} \left|(-1) (x - 3) (n + 1)\right| &= \left|(-1)(0)(n + 1)\right| \\ &= 0 < M \end{aligned}$$

Therefore, the above series will always converge to the solution x = 3, which is always the case. We have $$begin aligned left|(-1) (x - 3) (n + 1)right| &leq M |x - 3| &leq fracM|n + 1| &begin aligned end aligned for the values of $x$ other than 3.$$

A square matrix A is diagonalizable if it is similar to a diagonal matrix D: D = P-¹AP, where P is an invertible matrix. Diagonalizable matrices are of great importance in the study of linear transformations and differential equations. There are three equivalent conditions for a matrix A to be diagonalizable:

it has n linearly independent eigenvectors, the sum of the dimensions of the eigenspaces of A equals n, or it has n linearly independent generalized eigenvectors.The matrix P that satisfies P-¹AP = D can be obtained by taking the eigenvectors of A as the columns of P, and then finding the inverse of P. To find the eigenvectors of A, we solve the characteristic equation det(A - λI) = 0 to get the eigenvalues, and then solve the system (A - λI)x = 0 to get the eigenvectors. If A has n distinct eigenvalues, then A is diagonalizable. Otherwise, A is not diagonalizable if there are fewer than n linearly independent eigenvectors.

Given matrix is A = [53 -11 2; 0 A 0; lo 2 0 7], so we find the eigenvalues and eigenvectors of this matrix. Let λ be an eigenvalue of A and x be the corresponding eigenvector, such that Ax = λx. The characteristic equation is det(A - λI) = 0, where I is the identity matrix of the same size as A. det(A - λI) = (53 - λ)((A - λ)(0 2; 1 0) - 11(-1)2) - 2(-1)(lo)(0 2) = (53 - λ)(λ² - Aλ - 4) - 20 = 0. This is a cubic equation in λ, so it has three roots, which may be real or complex. We can use the rational root theorem to find some possible rational roots of the cubic polynomial, and then use synthetic division to factorize the polynomial. If we find a rational root, then we can factorize the polynomial and solve for the other roots using the quadratic formula. If we don't find a rational root, then we have to use the cubic formula to find all three roots. We can also use numerical methods to find the roots, such as bisection, Newton's method, or the secant method.

In order to find a nonsingular matrix P such that P-¹AP is diagonal, we need to find the eigenvectors of A and construct the matrix P with these eigenvectors as columns. We then compute the inverse of P and check that P-¹AP is diagonal. We can verify that P-¹AP is diagonal by computing its entries and comparing them to the eigenvalues of A. If P-¹AP is diagonal, then the matrix P orthogonally diagonalizes A, since P is an orthogonal matrix. We can verify that PT AP is diagonal by computing its entries and comparing them to the eigenvalues of A. If PT AP is diagonal, then A is orthogonally diagonalizable.

The function f(x, y) = 7e*sin(y), we can find the gradient vector Vf(x, y) and evaluate it at a specific point. Therefore, the directional derivative of the function at the point (0, 1) in the direction of the vector v = (-3, 4) is 28e*cos(1)/5.

To find the gradient vector Vf(x, y) of the function f(x, y) = 7esin(y), we take the partial derivatives with respect to x and y: Vf(x, y) = (∂f/∂x, ∂f/∂y) = (0, 7ecos(y)).

To determine Vf(x, y) at the point (0, 1), we substitute the values into the gradient vector: Vf(0, 1) = (0, 7e*cos(1)).

To find a unit vector in the direction of the vector v = (-3, 4), we normalize the vector by dividing each component by its magnitude. The magnitude of v is √((-3)^2 + 4^2) = 5. Therefore, the unit vector u is (-3/5, 4/5).

For the directional derivative of the function f(x, y) = 7esin(y) at a given point in the direction of the vector v, we take the dot product of the gradient vector Vf(0, 1) = (0, 7ecos(1)) and the unit vector u = (-3/5, 4/5): Vf(0, 1) · u = (0 · (-3/5)) + (7ecos(1) · (4/5)) = 28ecos(1)/5.

We are supposed to use the limit definition of partial derivatives to demonstrate that both fr(0, 0) and f₂(0, 0) exist.

The first partial derivative can be obtained by holding y constant and taking the limit as x approaches zero. Then, we have:

where a and b are the starting and ending values of t, and x'(t) and y'(t) are the derivatives of x(t) and y(t) with respect to t, respectively.

First, let's find the derivatives of x(t) and y(t). Taking the derivatives, we get:

x'(t) = 2t + 23

y'(t) = 2t + 23

Next, we can plug these derivatives into the arc length formula and integrate from t = 0 to t = 7:

L = ∫(0 to 7) √[(2t + 23)² + (2t + 23)²] dt

Simplifying under the square root, we have:

The differential equation (dy/dx) + y² = xy² with the initial condition y(0) = 1 does not have an elementary closed-form solution.

To solve the differential equation (dy/dx) + y² = xy² with the initial condition y(0) = 1, we can use the method of separable variables. Rearranging the equation, we have,

(dy/dx) = xy² - y²

Next, we separate the variables by dividing both sides by (xy² - y²),

1/(xy² - y²) dy = dx

Now, we integrate both sides,

∫1/(xy² - y²) dy = ∫dx

To integrate the left side, we can use partial fraction decomposition,

∫[1/((y-1)(y+1))] dy = ∫dx

The partial fraction decomposition gives,

(1/2)∫[1/(y-1) - 1/(y+1)] dy = ∫dx

Now we can integrate,

(1/2)ln|y-1| - (1/2)ln|y+1| = x + C

Applying the initial condition y(0) = 1, we substitute x = 0 and y = 1 into the equation,

(1/2)ln|1-1| - (1/2)ln|1+1| = 0 + C

(1/2)ln|0| - (1/2)ln|2| = C

Since ln|0| is undefined, we can see that the term (1/2)ln|y-1| is not defined for y = 1. Therefore, we need to consider a different approach.

The differential equation (dy/dx) + y² = xy² is a first-order nonlinear ordinary differential equation. It does not have an elementary closed-form solution, and the initial condition y(0) = 1 does not provide a unique solution. Instead, we can solve the equation numerically or use approximation methods to find an approximate solution.

To find the Taylor series expansion for f(x) = cos(2x) centered at a, we need to compute the derivatives of f(x) and evaluate them at a. Let's start by finding the derivatives:

f(x) = cos(2x)

f'(x) = -2sin(2x)

f''(x) = -4cos(2x)

f'''(x) = 8sin(2x)

Now, let's evaluate these derivatives at a = 0:

f(0) = cos(2*0) = cos(0) = 1

f'(0) = -2sin(2*0) = -2sin(0) = 0

f''(0) = -4cos(2*0) = -4cos(0) = -4

f'''(0) = 8sin(2*0) = 8sin(0) = 0

The Taylor series expansion for f(x) = cos(2x) centered at a = 0 can be written as:

f(x) = f(0) + f'(0)(x-0) + (1/2!)f''(0)(x-0)² + (1/3!)f'''(0)(x-0)³ + ...

Substituting the values we obtained earlier, the first few terms of the Taylor series are:

f(x) = 1 + 0(x-0) - (1/2!)*4(x-0)² + (1/3!)*0(x-0)³ + ...

Simplifying, we have:

f(x) = 1 - 2(x²) + 0(x³) + ...

Therefore, the first four non-zero terms of the Taylor series for f(x) = cos(2x) centered at a = 0 are:

1 - 2(x²) + 0(x³) - ...

The given infinite geometric series has a common ratio of 4. The formula for the nth partial sum of an infinite geometric series is Sn = a(1 - rⁿ)/(1 - r), where a is the first term and r is the common ratio.For this series, a = 1 and r = 4. Plugging these values into the formula, we can calculate the partial sums as follows:

S₁ = 1

S₃ = 1(1 - 4³)/(1 - 4) = 21

S₄ = 1(1 - 4⁴)/(1 - 4) = 85

S₅ = 1(1 - 4⁵)/(1 - 4) = 341

As n increases, the value of Sn increases significantly. The terms in the series become larger and larger, leading to an unbounded sum.
