= = 2. Evaluate the line integral R = Scy?dx + xdy, where C is the arc of the parabola x = 4 – 42 from (-5, -3) to (0,2).

Answers

Answer 1

The line integral R = Scy?dx + xdy, where C is the arc of the parabola x = 4 – 42 from (-5, -3) to (0,2) is 28.

Let's have detailed explanation:

1. Rewrite the line integral:

                          R = ∫C (4 - y2)dx + xdy

2. Substitute the equations of the line segment C into the line integral:

                          R = ∫(-5,-3)->(0,2) (4 - y2)dx + xdy

3. Solve the line integral:

            R = ∫(-5,-3)->(0,2) 4dx - ∫(-5,-3)->(0,2) y2dx + ∫(-5,-3)->(0,2) xdy

            R = 4(0-(-5)) – ∫(-5,-3)->(0,2) y2dx + ∫(-5,-3)->(0,2) xdy

            R = 20 – ∫(-5,-3)->(0,2) y2dx + ∫(-5,-3)->(0,2) xdy

4. Use the Fundamental Theorem of Calculus to solve the line integrals:

                R = 20 – [y2] (−5,2) + [x] (−5,0)

                R = 20 – (−22 + 32) + (0 – (−5))

                R = 28

Find the particular antiderivative of the following derivative that satisfies the given condition. C'(x) = 4x² - 2x; C(O) = 5,000 C(x) =

Answers

The particular antiderivative of C'(x) = 4x^2 - 2x that satisfies the condition C(0) = 5,000 is C(x) = (4/3)x^3 - (2/2)x^2 + 5,000.

To find the particular antiderivative C(x) of the derivative C'(x) = 4x^2 - 2x, we integrate the derivative with respect to x.

The antiderivative of 4x^2 - 2x with respect to x is given by the power rule of integration. For each term, we add 1 to the exponent and divide by the new exponent. So, the antiderivative becomes:

C(x) = (4/3)x^3 - (2/2)x^2 + C

Here, C is the constant of integration.

To find the particular antiderivative that satisfies the given condition C(0) = 5,000, we substitute x = 0 into the antiderivative equation:

C(0) = (4/3)(0)^3 - (2/2)(0)^2 + C

C(0) = 0 + 0 + C

C(0) = C

We know that C(0) = 5,000, so we set C = 5,000:

C(x) = (4/3)x^3 - (2/2)x^2 + 5,000

Answers

In questions 9-12, we are given two lines l1 and l2. In part (a), we determine whether l1 and l2 are parallel, perpendicular, or neither, and find the distance between the lines. In part (b), we find an equation for the plane that contains both lines.

9. (a) To determine whether l1 and l2 are parallel, perpendicular, or neither, we examine their direction vectors. The direction vector of l1 is (-3, 4, -1) and the direction vector of l2 is (1, 3, -4). Since the dot product of the direction vectors is not zero, l1 and l2 are neither parallel nor perpendicular.

To find the distance between the lines, we can use the formula for the distance between a point and a line. We select a point on one line, such as (2, -1, 1) on l1, and find the shortest distance to the other line. The distance between the lines is the magnitude of the vector connecting the two points, which is obtained by taking the square root of the sum of the squares of the differences of the coordinates.

(b) To find an equation for the plane that contains both lines, we can use the cross product of the direction vectors of l1 and l2 to find a normal vector to the plane. The normal vector is obtained by taking the cross product of (-3, 4, -1) and (1, 3, -4). This gives us a normal vector of (5, 13, 13).

Using the coordinates of a point on one of the lines, such as (2, -1, 1) on l1, we can write the equation of the plane as 5(x - 2) + 13(y + 1) + 13(z - 1) = 0.

Therefore, l1 and l2 are neither parallel nor perpendicular, the distance between the lines can be found using the formula for the distance between a point and a line, and the equation of the plane that contains both lines can be determined using the cross-product of the direction vectors and a point on one of the lines.

Answers

a. The vector from (2, -7, 0) to (1, -3, -5)  is (-1, 4, -5).

b.  The vector from (1, -3, -5) to (2, -7, 0) is (1, -4, 5).

c. The position vector for (-90, 4) is (-90, 4).

(a) The vector from (2, -7, 0) to (1, -3, -5):

To find the vector between two points, we subtract the coordinates of the initial point from the coordinates of the final point. Therefore, the vector can be calculated as follows:

(1 - 2, -3 - (-7), -5 - 0) = (-1, 4, -5)

So, the vector from (2, -7, 0) to (1, -3, -5) is (-1, 4, -5).

(b) The vector from (1, -3, -5) to (2, -7, 0):

Similarly, we subtract the coordinates of the initial point from the coordinates of the final point to find the vector:

(2 - 1, -7 - (-3), 0 - (-5)) = (1, -4, 5)

Therefore, the vector from (1, -3, -5) to (2, -7, 0) is (1, -4, 5).

(c) The position vector for (-90, 4):

The position vector describes the vector from the origin (0, 0, 0) to a specific point. In this case, the position vector for (-90, 4) can be found as follows:

(-90, 4) - (0, 0) = (-90, 4)

Thus, the position vector for (-90, 4) is (-90, 4). This vector represents the displacement from the origin to the point (-90, 4) and can be used to describe the location or direction from the origin to that specific point in space.

Answers

The value of the limit is equal to the value of the function at a = -1, we can conclude that the function f(x) = (x + 2a³) is continuous at a = -1.

Let's start with problem 13.

Given function:

[tex]f(a) = (x + 2a³), a = -1[/tex]

To show that the function is continuous at a = -1, we need to evaluate the following limit:

[tex]lim(x→a) f(x) = f(-1) = (-1 + 2(-1)³)[/tex]

First, let's simplify the expression:

[tex]f(-1) = (-1 + 2(-1)³)= (-1 + 2(-1))= (-1 - 2)= -3[/tex]

Therefore, we have determined the value of the function at a = -1 as -3.

Now, let's evaluate the limit as x approaches -1:

[tex]lim(x→-1) f(x) = lim(x→-1) (x + 2(-1)³)[/tex]

Substituting x = -1:

[tex]lim(x→-1) f(x) = lim(x→-1) (-1 + 2(-1)³)= lim(x→-1) (-1 + 2(-1))= lim(x→-1) (-1 - 2)= lim(x→-1) (-3)= -3[/tex]

Since the value of the limit is equal to the value of the function at a = -1, we can conclude that the function f(x) = (x + 2a³) is continuous at a = -1.

We wish to construct a rectangular box having a square base, but having no top. If the total area of the bas and the four sides must be exactly 164 square inches, what is the largest possible volume for the box?

Answers

The largest possible volume for the rectangular box is approximately 160.57 cubic inches. Let x be the side of the square base and h be the height of the rectangular box.

The surface area of the base and four sides is:

SA = x² + 4xh

The volume of the rectangular box is:

V = x²h

We want to maximize the volume of the box subject to the constraint that the surface area is 164 square inches. That is  

SA = x² + 4xh = 164

Therefore:h = (164 - x²) / 4x

We can now substitute this expression for h into the formula for the volume:

V = x²[(164 - x²) / 4x]

Simplifying this expression, we get:V = (1 / 4)x(164x - x³)

We need to find the maximum value of this function. Taking the derivative and setting it equal to zero, we get:dV/dx = (1 / 4)(164 - 3x²) = 0

Solving for x, we get

x = ±√(164 / 3)

We take the positive value for x since x represents a length, and the side length of a box must be positive. Therefore:x = √(164 / 3) ≈ 7.98 inches

To find the maximum volume, we substitute this value for x into the formula for the volume:V = (1 / 4)(√(164 / 3))(164(√(164 / 3)) - (√(164 / 3))³)V ≈ 160.57 cubic inches

Answers

The area of the surface given by z = f(x,y) that lies above the region R is (16/3) √51. To find the area of the surface given by z = f(x,y) that lies above the region R, we can use the formula for surface area: A = ∫∫√(1 +(f_x)^2 + (f_y)^2) dA

In this case, we have: f(x, y) = 5x + 5y

f_x = 5

f_y = 5

We also have the region R, which is the triangle with vertices (0, 0), (4,0), and (0, 4). To set up the integral, we need to find the limits of integration for x and y. Since the triangle has vertices at (0, 0), (4,0), and (0, 4), we can set up the integral as follows:

A = ∫∫√(1 + (f_x)^2 + (f_y)^2) dA

A = ∫_0^4 ∫_0^(4-x) √(1 + 5^2 + 5^2) dy dx

A = ∫_0^4 √51(4-x) dx

A = √51 ∫_0^4 (4-x)^(1/2) dx. To evaluate this integral, we can use the substitution u = 4-x, which gives us: du = -dx

x = 0 => u = 4

x = 4 => u = 0

Substituting these limits and the expression for x in terms of u into the integral, we get: A = √51 ∫_4^0 u^(1/2) (-du)

A = √51 ∫_0^4 u^(1/2) du

A = √51 (2/3) u^(3/2) |_0^4

A = (2/3) √51 (4^(3/2) - 0)

A = (2/3) √51 (8)

A = (16/3) √51

Find the flux of the vector field F = (y; – 2, 2) across the part of the plane z = 1+ 4x + 3y above the rectangle (0, 3) x (0,4) with upwards orientation

Answers

The flux of the vector field F = (y, -2, 2) across the part of the plane

z = 1+ 4x + 3y above the rectangle (0, 3) x (0,4) with upwards orientation is 96 Wb.

To find the flux of the vector field F = (y, -2, 2) across the given surface, we can use the surface integral formula. The flux (Φ) of a vector field across a surface S is given by:

Φ = ∬S F · dS

where F is the vector field, dS is the outward-pointing vector normal to the surface, and the double integral is taken over the surface S.

In this case, the surface S is the part of the plane z = 1 + 4x + 3y above the rectangle (0, 3) × (0, 4).

Let's parameterize the surface S. Let's introduce two parameters u and v to represent the coordinates on the rectangle. We can define the position vector r(u, v) = ( x(u, v), y(u, v), z(u, v) ) as follows:

x(u, v) = u

y(u, v) = v

z(u, v) = 1 + 4u + 3v

Next, we calculate the partial derivatives of r(u, v) with respect to u and v:

∂r/∂u = (1, 0, 4)

∂r/∂v = (0, 1, 3)

Now, we can calculate the cross product of the partial derivatives:

∂r/∂u × ∂r/∂v = (-4, -3, 1)

The magnitude of this cross product is the area of the parallelogram defined by ∂r/∂u and ∂r/∂v, which is √((-4)^2 + (-3)^2 + 1^2) = √26.

To find the flux Φ, we integrate the dot product of F and the outward-pointing vector dS over the surface S:

Φ = ∬S F · dS = ∬S (y, -2, 2) · (∂r/∂u × ∂r/∂v) du dv

Since the outward-pointing vector is ∂r/∂u × ∂r/∂v = (-4, -3, 1), we have:

Φ = ∬S (y, -2, 2) · (-4, -3, 1) du dv

  = ∬S (-4y + 6 + 2) du dv

  = ∬S (-4y + 8) du dv

The limits of integration are u = 0 to 3 and v = 0 to 4, representing the rectangle (0, 3) × (0, 4). Therefore, the integral becomes:

Φ = ∫₀³ ∫₀⁴ (-4y + 8) dv du

Now, let's evaluate the integral:

Φ = ∫₀³ ∫₀⁴ (-4y + 8) dv du

  = ∫₀³ [-4yv + 8v]₀⁴ du

  = ∫₀³ (-16y + 32) du

  = [-16yu + 32u]₀³

  = -48y + 96

Finally, we substitute the limits of integration for y:

Φ = -48y + 96 = -48 *4  + 96 = -192 + 96 = -96

Thus, the required flux is 96 Wb

Answers

To determine f'(x) for the function f(x) = 4x + 7 using the definition of the derivative, the Newton quotient is computed and simplified to eliminate h in the denominator.

The derivative of a function f(x) can be found using the definition of the derivative, which involves the Newton quotient. For the function f(x) = 4x + 7, we calculate f'(x) by evaluating the Newton quotient.

The Newton quotient is given by (f(x + h) - f(x)) / h, where h represents a small change in x.

Substituting f(x) = 4x + 7 into the Newton quotient, we have [(4(x + h) + 7) - (4x + 7)] / h.

Simplifying the expression inside the numerator, we get (4x + 4h + 7 - 4x - 7) / h.

Canceling out the terms that have opposite signs, we are left with (4h) / h.

Now, we can cancel out the h in the numerator and denominator, resulting in the derivative f'(x) = 4.

Therefore, the derivative of the function f(x) = 4x + 7 with respect to x, denoted as f'(x), is equal to 4.

Answers

1. Using Newton's method, the only critical number of the function f(x) = ln(1 + x - x^2 + x^3) is approximately 0.789813.

2. The equation of the line passing through the point (3,5) that cuts off the least area from the first quadrant is y = -(5/3)x + 20/3.

3. The function f(x) = sin(x^2) - 137x + 231 is the function that passes through the point (137, 0) and has a derivative function of f'(x) = 12x cos(x^2).

To find the critical number of the function f(x) = ln(1 + x - x^2 + x^3), we can apply Newton's method.

The derivative of f(x) is given by f'(x) = (1 - 2x + 3x^2) / (1 + x - x^2 + x^3). By iteratively applying Newton's method with an initial guess, we can approximate the critical number. The process continues until we reach the desired level of accuracy. In this case, the critical number is approximately 0.789813.

To find the line passing through the point (3,5) that cuts off the least area from the first quadrant, we need to minimize the area of the triangle formed by the line, the x-axis, and the y-axis.

The equation of a line passing through (3,5) can be written as y = mx + c, where m represents the slope and c is the y-intercept. By minimizing the area of the triangle, we minimize the product of the base and height.

This occurs when the line is perpendicular to the x-axis, resulting in the least area. Therefore, the line equation is y = -(5/3)x + 20/3.

To find the function f(x) that passes through the point (137, 0) and has a derivative function of f'(x) = 12x cos(x^2), we integrate the derivative function with respect to x.

Integrating f'(x) gives us f(x) = sin(x^2) - 137x + C, where C is the constant of integration. To determine the value of C, we substitute the given point (137, 0) into the equation. This gives us 0 = sin(137^2) - 137(137) + C, which allows us to solve for C. The resulting function is f(x) = sin(x^2) - 137x + 231.

b) Interval of increase and decrease
c) relative coordinates minimum and maximum
d) inflections
e) concaves
y= 3x4 – 24x + . 3 2 - 24x + 54x + 4 --

Answers

a) The critical points of the equation are (-2, 66) and (2, -66).

b) The interval of increase is (-∞, -2) U (2, ∞), and the interval of decrease is (-2, 2).

c) The relative minimum is (-2, 66), and the relative maximum is (2, -66).

d) There are no inflection points in the equation.

e) The concave is upward for the entire graph.

What are the key characteristics of the equation?

The given equation is y = 3x⁴ - 24x³ + 32 - 24x + 54x + 4.

To determine its critical points, we find the values of x where the derivative of y equals zero.

By taking the derivative, we obtain 12x³ - 72x² - 24, which can be factored as 12(x - 2)(x + 2)(x - 1).

Thus, the critical points are (-2, 66) and (2, -66).

Analyzing the derivative further, we observe that it is positive in the intervals (-∞, -2) and (2, ∞), indicating an increasing function, and negative in the interval (-2, 2), suggesting a decreasing function.

The relative minimum occurs at (-2, 66), and the relative maximum at (2, -66).

There are no inflection points in the equation, and the concave is upward for the entire graph.

The critical points of a function are the points where the derivative is either zero or undefined.

In this case, we found the critical points by setting the derivative of the equation equal to zero. The interval of increase represents the x-values where the function is increasing, while the interval of decrease represents the x-values where the function is decreasing.

The relative minimum and maximum are the lowest and highest points on the graph, respectively, within a specific interval. Inflection points occur where the concavity of the graph changes, but in this equation, no such points exist. The concave being upward means that the graph curves in a U-shape.

Understanding these characteristics helps us analyze the behavior of the equation and its graphical representation.

A car leaves an intersection traveling west. Its position 5 sec later is 30 ft from the intersection. At the same time, another car leaves the same intersection heading north so that its position t sec later is y = t + 4t ft from the intersection. If the speed of the first car 5 sec after leaving the intersection is 11 ft/sec, find the rate at which the distance between the two cars is changing at that instant of time. (Round your answer to two decimal places.) ---Select---

Answers

The rate at which the distance between the two cars is changing at the instant when the first car's speed is 11 ft/sec, 5 seconds after leaving the intersection, is 9 ft/sec.

Let's denote the distance between the first car and the intersection as x and the distance between the second car and the intersection as y. We are given that at time t, y = t + 4t ft.

At the instant when the first car's speed is 11 ft/sec, 5 seconds after leaving the intersection, we have x = 30 ft and y = 11 × 5 = 55 ft.

The distance between the two cars, D, is given by the Pythagorean theorem: D = √(x² + y²).

Taking the derivative of D with respect to time, we get dD/dt = (dD/dx) × (dx/dt) + (dD/dy) × (dy/dt).

Since dx/dt represents the speed of the first car, which is constant at 11 ft/sec, and dy/dt represents the rate at which the second car's position changes, which is 1 + 4 = 5 ft/sec, the equation simplifies to dD/dt = (dD/dx) × 11 + (dD/dy) × 5.

To find dD/dt, we differentiate D = √(x² + y²) with respect to x and y, respectively. By substituting the values x = 30 and y = 55, we find dD/dt = (30/√305) × 11 + (55/√305) × 5 ≈ 9 ft/sec. Therefore, the rate at which the distance between the two cars is changing at that instant of time is approximately 9 ft/sec.

1.For the curve given by x=sin^3θ, y=cos^3θ, find the slope and concavity at θ=π/6.

2. Find the arc length of the curve x=3sinθ−sin3θ, y=3cosθ−cos3θ, 0≤θ≤π/2.

3. Find an equation in rectangular coordinates for the surface represented by the spherical equation ϕ=π/6.

Answers

1. The concavity is constant

2. the arc length of curve is ∫[0, π/2] √[18 - 18(cosθcos3θ + sinθsin3θ)] dθ

3. The equation in rectangular coordinates are

x = (ρ/2)cosθ

y = (ρ/2)sinθ

z = (√3/2)ρ

How to find the slope and concavity?

1. To find the slope and concavity at θ = π/6 for the curve x = [tex]sin^3\theta\\[/tex], y = [tex]cos^3\theta[/tex], we can differentiate the equations with respect to θ and evaluate the derivatives at the given angle.

Differentiating x = [tex]sin^3\theta[/tex] and y = [tex]cos^3\theta[/tex] with respect to θ, we get:

dx/dθ =[tex]3sin^2\theta cos\theta[/tex]

dy/dθ = [tex]-3cos^2\theta sin\theta[/tex]

To find the slope at θ = π/6, we substitute θ = π/6 into the derivatives:

dx/dθ =[tex]3sin^2(\pi/6)cos(\pi/6)[/tex] = (3/4)(√3/2) = (3√3)/8

dy/dθ = [tex]-3cos^2(\pi/6)sin(\pi /6)[/tex] = -(3/4)(1/2) = -3/8

So, the slope at θ = π/6 is (3√3)/8 for x and -3/8 for y.

To find the concavity at θ = π/6, we need to differentiate the slopes with respect to θ:

d²x/dθ² = d/dθ[(3√3)/8] = 0 (constant)

d²y/dθ² = d/dθ[-3/8] = 0 (constant)

Therefore, the concavity at θ = π/6 is constant (neither concave up nor concave down).

How to find the arc length of the curve x = 3sinθ - sin3θ, y = 3cosθ - cos3θ?

2. To find the arc length of the curve x = 3sinθ - sin3θ, y = 3cosθ - cos3θ, where 0 ≤ θ ≤ π/2, we can use the arc length formula for parametric curves:

Arc length = ∫[a,b] sqrt[(dx/dθ)² + (dy/dθ)²] dθ

In this case, a = 0 and b = π/2. We need to find dx/dθ and dy/dθ:

dx/dθ = 3cosθ - 3cos3θ

dy/dθ = -3sinθ + 3sin3θ

Now, we can substitute these derivatives into the arc length formula and integrate:

Arc length =[tex]\int_0^{\pi/2} \sqrt{(3cos\theta - 3cos3\theta)^2 + (-3sin\theta + 3sin3\theta)^2} d\theta[/tex]

Using trigonometric identities, we have:

(3cosθ - 3cos3θ)² + (-3sinθ + 3sin3θ)²

= 9cos²θ - 18cosθcos3θ + 9cos²3θ + 9sin²θ - 18sinθsin3θ + 9sin²3θ

= 9(cos²θ + sin²θ) + 9(cos²3θ + sin²3θ) - 18(cosθcos3θ + sinθsin3θ)

Using the Pythagorean identity (cos²θ + sin²θ = 1) and the triple-angle formulas (cos³θ = (cosθ)³ - 3cosθ(1 - (cosθ)²) and sin³θ = 3sinθ - 4(sinθ)³), we can simplify further:

= 9 + 9 - 18(cosθcos3θ + sinθsin3θ)

= 18 - 18(cosθcos3θ + sinθsin3θ)

Now, the integral becomes:

∫[0, π/2] √[18 - 18(cosθcos3θ + sinθsin3θ)] dθ

This integral represents the arc length of the curve x = 3sinθ - sin3θ, y = 3cosθ - cos3θ, from θ = 0 to θ = π/2.

How to find an equation in rectangular coordinates for the surface represented by the spherical equation?

x = ρsinϕcosθ

y = ρsinϕsinθ

z = ρcosϕ

In this case, the spherical equation is given as ϕ = π/6. Substituting ϕ = π/6 into the conversion formulas, we have:

y = ρsin(π/6)sinθ = (ρ/2)sinθ

z = ρcos(π/6) = (√3/2)ρ

Gas is escaping at a spherical balloon at a rate of 2 in^2/min. How fast is the surface changing when the radius is 12 inch?

Answers

The surface area of the balloon is changing at a rate of 192π square inches per minute when the radius is 12 inches. In other words, it is changing at a rate of 0.0053 in/min.

To find how fast the surface area is changing with respect to time, we need to use the formula for the surface area of a sphere.

The formula for the surface area (A) of a sphere with radius (r) is given by:

A = 4πr^2.

Given that the rate of change of the radius (dr/dt) is 2 in/min, we want to find the rate of change of the surface area (dA/dt) when the radius is 12 inches.

Differentiating the equation for the surface area with respect to time, we have:

dA/dt = d(4πr^2)/dt.

Using the power rule of differentiation, we get:

dA/dt = 8πr(dr/dt).

Substituting the given values, when r = 12 inches and dr/dt = 2 in/min, we have:

dA/dt = 8π(12)(2) = 192π in^2/min.

Therefore, the surface area of the balloon is changing at a rate of 192π square inches per minute when the radius is 12 inches.

3. Determine the derivative of f(x) from First Principles. f(x)= 8x3 - Vex+T a bx+c

Answers

The derivative of f(x) = 8x³ - Vex + T + abx + c, found using first principles, is f'(x) = 24²2 + ab. This derivative represents the rate of change of the function with respect to x.

To find the derivative of the function f(x) = 8x³ - Vex + T + abx + c using first principles, we need to apply the definition of the derivative:

f'(x) = lim(h->0) [f(x+h) - f(x)] / h

Let's calculate it step by step

Replace f(x) with the given function:

f'(x) = lim(h->0) [(8(x+h)³ - Vex+h + T + ab(x+h) + c) - (8x³ - Vex + T + abx + c)] / h

Expand and simplify:

f'(x) = lim(h->0) [8(x³ + 3x²h + 3xh² + h³) - Vex+h + T + abx + abh + c - 8x^3 + Vex - T - abx - c] / h

Cancel out common terms:

f'(x) = lim(h->0) [8(3x²h + 3xh² + h³) + abh] / h

Distribute 8 into the terms inside the parentheses:

f'(x) = lim(h->0) [24x²h + 24xh² + 8h³ + abh] / h

Simplify and factor out h

f'(x) = lim(h->0) [h(24x² + 24xh + 8h² + ab)] / h

Cancel out h:

f'(x) = lim(h->0) 24x² + 24xh + 8h² + ab

Take the limit as h approaches 0:

f'(x) = 24x² + ab

Therefore, the derivative of f(x) = 8x³ - Vex + T + abx + c from first principles is f'(x) = 24x² + ab.

Answers

The order 3 Taylor polynomial for the function \(f(x) = 3x + 16\) is given by T3(x)=16+3x using exact values.

To find the order 3 Taylor polynomial \(T_3(x)\) for the function \(f(x) = 3x + 16\), we need to calculate the function's derivatives up to the third order and evaluate them at the center \(c = 0\). The formula for the Taylor polynomial is:

\[T_3(x) = f(0) + f'(0)x + \frac{f''(0)}{2!}x^2 + \frac{f'''(0)}{3!}x^3\]

Let's find the derivatives of \(f(x)\):

\[f'(x) = 3\]

\[f''(x) = 0\]

\[f'''(x) = 0\]

Now, let's evaluate these derivatives at \(x = 0\):

\[f(0) = 3(0) + 16 = 16\]

\[f'(0) = 3\]

\[f''(0) = 0\]

\[f'''(0) = 0\]

Substituting these values into the formula for the Taylor polynomial, we get:

\[T_3(x) = 16 + 3x + \frac{0}{2!}x^2 + \frac{0}{3!}x^3\]

Simplifying further:

\[T_3(x) = 16 + 3x\]

Answers

Naya's gross annual income is approximately $46,416.67.

To determine Naya's gross annual income, we need to reverse engineer the tax calculation based on the given information.

Let's denote Naya's gross annual income as G. We know that Naya's net annual income, after income tax, is 36,560. We also know that Naya pays income tax at the same rates and has the same annual tax credits as Emma.

Emma pays income tax on her taxable income at a rate of 20% on the first 35,300 and 40% on the balance. She has annual tax credits of 1,650.

Based on this information, we can set up the following equation:

G - (0.2 * 35,300) - (0.4 * (G - 35,300)) = 36,560 - 1,650

Let's solve this equation step by step:

G - 7,060 - 0.4G + 14,120 = 34,910

Combining like terms, we have:

0.6G + 7,060 = 34,910

Subtracting 7,060 from both sides:

0.6G = 27,850

Dividing both sides by 0.6:

G = 27,850 / 0.6

G ≈ 46,416.67

Therefore, Naya's gross annual income is approximately $46,416.67.

Answers

To evaluate the work done by the force field F = (2xy² + 3xz², 2x²y + 2y, 3x²z), we need to compute the line integral of F along the path C from (0,1,0) to (2,3,2).

The line integral of a vector field F along a curve C is given by the formula:

∫ F · dr = ∫ (F₁dx + F₂dy + F₃dz),

where dr is the differential vector along the curve C.

Parametrize the curve C as r(t) = (2t, 1+t, 2t), where t ranges from 0 to 1. Taking the derivatives, we find dr = (2dt, dt, 2dt).

Substituting these values into the line integral formula, we have:

∫ F · dr = ∫ ((2xy² + 3xz²)dx + (2x²y + 2y)dy + (3x²z)dz)

          = ∫ (4ty² + 6tz² + 2(1+t)dt + 6t²zdt + 6t²dt)

          = ∫ (4ty² + 6tz² + 2 + 2t + 6t²z + 6t²)dt

          = ∫ (6t² + 4ty² + 6tz² + 2 + 2t + 6t²z)dt.

Integrating term by term, we get:

∫ (6t² + 4ty² + 6tz² + 2 + 2t + 6t²z)dt = 2t³ + (4/3)ty³ + 2tz² + 2t² + t²z + 2t³z.

Evaluating this expression from t = 0 to t = 1, we find:

∫ F · dr = 2(1)³ + (4/3)(1)(1)³ + 2(1)(2)² + 2(1)² + (1)²(2) + 2(1)³(2)

          = 2 + (4/3) + 8 + 2 + 2 + 16

          = 30/3 + 16

          = 10 + 16

          = 26.

Therefore, the work done by the force field F in moving the object along the path C is 26 units.
