Which of the following sets of functions are linearly independent on the interval (-00.c.)? (i) fi(x) = 10 +x, f(x) = 4x, f(x) = x+8 (ii) fi(x) = Oxf2(x) = 8e9f3(x) = (3x ( (iii) fi(x) = 10sin?x, f(x)

The conclusion of the Mean Value Theorem: the derivative of f evaluated at c, f'(c), is equal to average rate of change of f(x) over interval [0, 9], which is given by (f(9) - f(0))/(9 - 0) = (√9 - √0)/9 = 1/3.

The function f(x) = √x satisfies the two hypotheses of  the Mean Value Theorem on the interval [0, 9]. The hypotheses are as follows:

f(x) is continuous on the closed interval [0, 9]: The function f(x) = √x is continuous for all non-negative real numbers. Thus, f(x) is continuous on the closed interval [0, 9].

f(x) is differentiable on the open interval (0, 9): The derivative of f(x) = √x is given by f'(x) = (1/2) * x^(-1/2), which exists and is defined for all positive real numbers. Therefore, f(x) is differentiable on the open interval (0, 9).

The conclusion of the Mean Value Theorem states that there exists at least one number c in the open interval (0, 9) such that the derivative of f evaluated at c, f'(c), is equal to the average rate of change of f(x) over the interval [0, 9], which is given by (f(9) - f(0))/(9 - 0) = (√9 - √0)/9 = 1/3. In other words, there exists a value c in (0, 9) such that f'(c) = 1/3.

The inner product of u and v is -150.the geometric interpretation of the inner product is related to the concept of the angle between two vectors.

to find the inner product of u and v, we can use the formula:

u · v = u1 * v1 + u2 * v2 + u3 * v3

given that u = [4, 16, 1] and v = [3, -10, -2], we can substitute the values into the formula:

u · v = 4 * 3 + 16 * (-10) + 1 * (-2)      = 12 - 160 - 2

     = -150 the inner product can be used to determine the angle between two vectors using the formula:

cosθ = (u · v) / (||u|| * ||v||)

where θ is the angle between the vectors u and v, and u and v are the magnitudes of the vectors u and v, respectively.

in this case, since the inner product of u and v is negative (-150), it indicates that the angle between the vectors is obtuse (greater than 90 degrees). the magnitude of the inner product also gives an indication of how "close" or "aligned" the vectors are. in this case, the negative value indicates that the vectors u and v are pointing in somewhat opposite directions or have a significant angle between them.

We cannot express the vector field (4x + 5y, 3x + 2y, 0) as the sum of a curl-free vector field and a divergence-free vector field, as it does not satisfy the properties of being curl-free or divergence-free.

to express the vector field (4x + 5y, 3x + 2y, 0) as the sum of a curl-free vector field and a divergence-free vector field, we need to find vector fields that satisfy the properties of being curl-free and divergence-free.

a vector field is curl-free if its curl is zero, and it is divergence-free if its divergence is zero.

let's start by finding the curl of the given vector field:

curl(f) = ∇ × f,

where f = (4x + 5y, 3x + 2y, 0).

taking the curl, we have:

curl(f) = (0, 0, ∂(3x + 2y)/∂x - ∂(4x + 5y)/∂y)        = (0, 0, 3 - 5)

       = (0, 0, -2).

since the z-component of the curl is non-zero, the given vector field is not curl-free.

next, let's find the divergence of the given vector field:

divergence(f) = ∇ · f,

where f = (4x + 5y, 3x + 2y, 0).

taking the divergence, we have:

divergence(f) = ∂(4x + 5y)/∂x + ∂(3x + 2y)/∂y + ∂0/∂z

            = 4 + 2             = 6.

since the divergence is non-zero, the given vector field is not divergence-free.

The solution to the differential equation y' + y = est + 2 with y(0) = 0 using laplace transform technique is y(t) = eᵗ + te⁽⁻ᵗ⁾.

to find the inverse laplace transform of the given function f(s), we need to simplify the expression and apply the properties of laplace transforms.

f(s) = (6 + 3 + 8 + 4) + (6 - 3) * 12     = 21 + 3 * 12

    = 21 + 36     = 57

now, let's solve the differential equation y' + y = est + 2 using the laplace transform technique.

applying the laplace transform to both sides of the equation, we get:

sy(s) - y(0) + y(s) = 1/(s - a) + 2/s

since y(0) = 0, the equation becomes:

sy(s) + y(s) = 1/(s - a) + 2/s

combining like terms:

(s + 1)y(s) = (s + 2)/(s - a)

now, solving for y(s):

y(s) = (s + 2)/(s - a) / (s + 1)

to simplify the right side, we can perform partial fraction decomposition:

y(s) = [a/(s - a)] + [b/(s + 1)]

(s + 2) = a(s + 1) + b(s - a)

expanding and equating coefficients:

1s + 2 = (a + b)s + (a - ab)

equating coefficients of like powers of s:

1 = a + b

2 = a - ab

solving these equations, we find:

a = 1/(1 - a)b = -a/(1 - a)

substituting these values back into the partial fraction decomposition, we get:

y(s) = [1/(1 - a)/(s - a)] + [-a/(1 - a)/(s + 1)]

taking the inverse laplace transform of y(s), we find the solution y(t):

The distance between the points with polar coordinates (1/6) and (3,3/4) is approximately 2.844 units.

To find the distance between the points with polar coordinates (1/6) and (3,3/4), we need to convert both points into Cartesian coordinates and then use the distance formula.

The first point (1/6) has a radius of 1/6 and an angle of 0 degrees (since it is on the positive x-axis). We can use the formula x = r cos(theta) and y = r sin(theta) to find the Cartesian coordinates:

x = (1/6) cos(0) = 1/6
y = (1/6) sin(0) = 0

So the first point is (1/6, 0).

The second point (3,3/4) has a radius of 3 and an angle of 53.13 degrees (which we can find using the inverse tangent function). Again using the formulas for converting polar to Cartesian coordinates:

x = 3 cos(53.13) = 1.83
y = 3 sin(53.13) = 2.31

So the second point is (1.83, 2.31).

Now we can use the distance formula:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

d = sqrt((1.83 - 1/6)^2 + (2.31 - 0)^2)

d = sqrt(2.756 + 5.3361)

d = sqrt(8.0921)

d = 2.844

The estimated equation for these data is: Y= 6.47 + 1.013x

When x = 6, the estimated value of y is approximately 12.55.

To compute the estimated regression equation and predict the value of y when x = 6, we'll follow these steps:

Given data:

xi: 2, 6, 9, 13, 20

yi: 7, 18, 9, 26, 23

a. Compute b0 and b1 and develop the estimated equation for these data.

Step 1: Calculate the means of x and y:

x = (2 + 6 + 9 + 13 + 20) / 5 = 10

y = (7 + 18 + 9 + 26 + 23) / 5 = 16.6

Step 2: Calculate the deviations from the means:

xi - x: -8, -4, -1, 3, 10

yi - y: -9.6, 1.4, -7.6, 9.4, 6.4

Step 3: Calculate the sum of squared deviations:

Σ(xi - x): 180

Σ(yi - y)²: 316.8

Step 4: Calculate the sum of cross-products:

Σ(xi - x)(yi - y): 182.4

Step 5: Calculate the slope (b1):

b1 = Σ(xi - x)(yi - y) / Σ(xi - x)² = 182.4 / 180 ≈ 1.013

Step 6: Calculate the intercept (b0):

b0 = y - b1 * x = 16.6 - 1.013 * 10 ≈ 6.47

Therefore, the estimated equation for these data is:

Y = 6.47 + 1.013x

b. Use the estimated regression equation to predict the value of y when x = 6.

To predict the value of y when x = 6, substitute x = 6 into the estimated equation:

y = 6.47 + 1.013 * 6

y ≈ 6.47 + 6.078

y ≈ 12.55

Thus, when x = 6, the estimated value of y is approximately 12.55.

The ordered pair representing the maximum value of the graph of the equation r = 10sin(e) is (0, 10).

In this equation, 'r' represents the radial distance from the origin, and 'e' represents the angle in radians. The graph of the equation is a sinusoidal curve that oscillates between -10 and 10.

The maximum value of the sine function occurs at an angle of 90 degrees or π/2 radians, where sin(π/2) equals 1. Since the radius 'r' is multiplied by 10, the maximum value of 'r' is 10. Thus, the ordered pair representing the maximum value is (0, 10), where the angle is π/2 radians and the radial distance is 10.

In the equation r = 10sin(e), the sine function determines the vertical component of the graph, while the angle 'e' controls the horizontal rotation of the graph. The sine function oscillates between -1 and 1, and when multiplied by 10, it stretches the graph vertically, resulting in a range of -10 to 10 for 'r'.

The maximum value of the sine function is 1, which occurs at an angle of 90 degrees or π/2 radians. At this angle, the ordered pair reaches its highest point on the graph. Since the radial distance 'r' is equal to 10 when the sine function is at its maximum, the ordered pair representing this point is (0, 10), where the x-coordinate is 0 (indicating no horizontal shift) and the y-coordinate is 10.

(a) ∫(x-3)/([tex]x^{3}[/tex]+9x) dx:

To solve this integral, we can start by factoring the denominator:

[tex]x^{3}[/tex] + 9x = x([tex]x^{2}[/tex] + 9)

Now we can use partial fraction decomposition to express the integrand as a sum of simpler fractions. Let's assume that:

(x-3)/([tex]x^{3}[/tex]+9x) = A/x + (Bx + C)/([tex]x^{2}[/tex] + 9)

Multiplying both sides by (x^3+9x) to clear the denominators, we have:

(x-3) = A([tex]x^{2}[/tex] + 9) + (Bx + C)x

Expanding and grouping like terms:

x - 3 = (A + B)[tex]x^{2}[/tex] + Cx + 9A

Comparing the coefficients of corresponding powers of x, we get the following equations:

A + B = 0 (for the [tex]x^{3}[/tex] terms)

C = 1 (for the x terms)

9A - 3 = 0 (for the constant terms)

From equation 1, we have B = -A. Substituting this into equation 3, we find:

9A - 3 = 0

9A = 3

A = 1/3

Therefore, B = -A = -1/3.

Now we can rewrite the integral as:

∫(x-3)/([tex]x^{3}[/tex]+9x) dx = ∫(1/x) dx + ∫(-1/3)(x/([tex]x^{3}[/tex]+9)) dx

The first term integrates to ln|x| + C1, and for the second term, we can use a substitution u = [tex]x^{2}[/tex] + 9, du = 2x dx:

∫(-1/3)(x/([tex]x^{2}[/tex]+9)) dx = (-1/3) ∫(1/u) du = (-1/3) ln|u| + C2

= (-1/3) ln|[tex]x^{2}[/tex]+9| + C2

Therefore, the solution to the integral is:

∫(x-3)/([tex]x^{3}[/tex]+9x) dx = ln|x| - (1/3) ln|[tex]x^{2}[/tex]+9| + C

(b) ∫[tex]tan^{4}[/tex](x) [tex]sec^{6}[/tex](x) dx:

To solve this integral, we can use the trigonometric identity:

[tex]sec^{2}[/tex](x) = 1 + [tex]tan^{2}[/tex](x)

Multiplying both sides by [tex]sec ^{4}[/tex](x), we have:

[tex]sec^{6}[/tex](x) = [tex]sec^{4}[/tex](x) +[tex]sec^{2}[/tex](x) [tex]tan^{2}[/tex](x)

Now we can rewrite the integral as:

∫[tex]tan^{4}[/tex](x) [tex]sec^{6}[/tex](x) dx = ∫[tex]tan^{4}[/tex](x) ([tex]sec^{4}[/tex](x) +[tex]sec^{2}[/tex](x) [tex]tan^{2}[/tex](x)) dx

Expanding and simplifying:

∫[tex]tan^{4}[/tex](x) [tex]sec^{6}[/tex](x) dx =  ∫[tex]tan^{4}[/tex](x) [tex]sec^{4}[/tex](x) dx + ∫[tex]tan^{6}[/tex](x) [tex]sec^{2}[/tex](x) dx

For the first integral, we can use the substitution u = sec(x), du = sec(x)tan(x) dx:

∫[tex]tan^{4}[/tex](x) [tex]sec^{4}[/tex](x) dx = ∫[tex]tan^{4}[/tex](x) [tex]sec^{2}[/tex](x)([tex]sec^{2}[/tex](x)tan(x)) dx

= ∫[tex]tan^{4}[/tex](x) [tex]sec^{2}[/tex](x) dx(du)

Now the integral becomes:

∫[tex]u^{4}[/tex]du = (1/5)[tex]u^{5}[/tex] + C1

= (1/5)[tex]sec^{5}[/tex](x) + C1

For the second integral, we can use the substitution u = tan(x), du =

[tex]sec^{2}[/tex](x) dx:

∫[tex]tan^{6}[/tex](x) [tex]sec^{2}[/tex](x) dx = ∫[tex]u^{6}[/tex] du

= (1/7)[tex]u^{7}[/tex] + C2

= (1/7)[tex]tan^{7}[/tex](x) + C2

Therefore, the solution to the integral is:

∫[tex]tan^{4}[/tex](x) [tex]sec^{6}[/tex](x) dx: = (1/5)[tex]sec^{5}[/tex](x) + (1/7)[tex]tan^{7}[/tex](x) + C

(c) ∫1/[tex](9-4x)^{\frac{3}{2} }[/tex] dx:

To solve this integral, we can use a substitution u = 9-4x, du = -4 dx:

∫1/[tex](9-4x)^{\frac{3}{2} }[/tex] dx = ∫-1/[tex]-4u^{\frac{3}{2} }[/tex] du

= ∫-1/(8[tex]u^{\frac{3}{2} }[/tex]) du

= (-1/8) ∫[tex]u^{\frac{-3}{2} }[/tex] du

= (-1/8) * (-2/1) [tex]u^{\frac{-1}{2} }[/tex]+ C

= (1/4)[tex]u^{\frac{-1}{2} }[/tex] + C

Substituting back u = 9-4x:

The polynomial f(x) with the given degree and zeros is:

[tex]f(x) = x^3 - 3ix^2 - 63ix - 90x - 108 - 81i[/tex]

To form a polynomial with the given degree and zeros, we know that complex zeros occur in conjugate pairs.

Given zeros: -3+3i, -3 (multiplicity 2)

Since -3 has a multiplicity of 2, it means it appears twice as a zero.

To form the polynomial, we can start by writing the factors corresponding to the zeros:

(x - (-3 + 3i))(x - (-3 + 3i))(x - (-3))

Simplifying the expressions:

(x + 3 - 3i)(x + 3 - 3i)(x + 3)

Now, we can multiply these factors together to obtain the polynomial:

(x + 3 - 3i)(x + 3 - 3i)(x + 3) = (x + 3 - 3i)(x + 3 - 3i)(x + 3)

Expanding the multiplication:

[tex](x^2 + 6x + 9 - 6ix - 3ix - 18i^2)(x + 3) = (x^2 + 6x + 9 - 6ix - 3ix + 18)(x + 3)[/tex]

Since [tex]i^2[/tex] is equal to -1:

To find the derivative of the function f(x) = 2 + x at x = 2 using the definition of the derivative, we start by applying the formula: f'(x) = lim(h->0) [f(x + h) - f(x)] / h.

Substituting x = 2 into the formula, we get: f'(2) = lim(h->0) [f(2 + h) - f(2)] / h. Now, let's evaluate the expression inside the limit: f(2 + h) = 2 + (2 + h) = 4 + h.  f(2) = 2 + 2 = 4. Substituting these values back into the formula, we have: f'(2) = lim(h->0) [(4 + h) - 4] / h.

Simplifying further, we get: f'(2) = lim(h->0) h / h. The h terms cancel out, and we are left with: f'(2) = lim(h->0) 1. Taking the limit as h approaches 0, we find that the derivative of f(x) = 2 + x at x = 2 is equal to 1.

Angle ∠LO = 113° (angle between sides OP and OQ)

Angle ∠LP = 18° (angle between sides OP and PQ)

The length of segment O as O. According to the law of sines, we can set up the following proportion:

sin(∠LO) / O = sin(∠POQ) / q

Substituting the known values, we have:

sin(113°) / O = sin(∠POQ) / 75

Now, we need to solve for O. We can rearrange the equation as follows:

O = (sin(113°) * 75) / sin(∠POQ)

To find the value of sin(∠POQ), we can use the fact that the sum of angles in a triangle is 180°. Therefore, ∠POQ = 180° - ∠LO - ∠LP = 180° - 113° - 18° = 49°.

Plugging in the values, we have:

O = (sin(113°) * 75) / sin(49°)

the value of O. Rounding the result to the nearest centimeter, we can determine the length of segment O in triangle AOPQ.

The field extension Q[√P,√] is a degree four extension of Q, and there exists an element a ∈ Q[√P,√] such that Q[√P,√] = Q[a]. Since p and q are distinct prime numbers.

To prove that Q[√P,√] is a degree four extension of Q, we can observe that each extension of the form Q[√P] is a degree two extension, as the minimal polynomial of √P over Q is x^2 - P. Similarly, Q[√P,√] is an extension of degree two over Q[√P], since the minimal polynomial of √ over Q[√P] is x^2 - √P.

Therefore, the composite extension Q[√P,√] is a degree four extension of Q.

To show that there exists an element a ∈ Q[√P,√] such that Q[√P,√] = Q[a], we can consider a = √P + √q. Since p and q are distinct prime numbers, √P and √q are linearly independent over Q. Thus, a is not in Q[√P] nor Q[√q]. By adjoining a to Q, we obtain Q[a], which is equal to Q[√P,√]. Hence, a is an element that generates the entire field extension Q[√P,√].

The area of inner loop of the given polar curve is approximately 4.7074 square units.

Finding the area of inner loop of the given polar curve involves utilizing Calculus 2 techniques. We begin by determining the bounds of theta where the inner loop occurs.

Since r = 1 - 3sin(θ), the inner loop is formed when 1 - 3sin(θ) is negative. Solving this inequality, we find that the inner loop exists when sin(theta) > 1/3. This occurs in the range of theta between arcsin(1/3) and pi - arcsin(1/3).

To find the area, we integrate the equation for the area of a polar region, which is given by A = 1/2 ∫[θ₁ to θ₂ (r²) d(theta).

Substituting r = 1 - 3sin(θ) into the formula and integrating within the bounds of theta, we obtain the area of the inner loop as approximately 4.7074 square units.

The given series Σ (2n + 1)!·(x + 7)^n converges for all values of x, not just when x = -7, using the ratio test.

To determine the convergence of the series Σ (2n + 1)!·(x + 7)^n, we can use the ratio test.

Applying the ratio test, we consider the limit:

lim(n→∞) |((2(n+1) + 1)!·(x + 7)^(n+1)) / ((2n + 1)!·(x + 7)^n)|

Simplifying the expression, we have:

lim(n→∞) |((2n + 3)(2n + 2)(2n + 1)!·(x + 7)^(n+1)) / ((2n + 1)!·(x + 7)^n)|

Canceling out the (2n + 1)! terms, we have:

lim(n→∞) |((2n + 3)(2n + 2)(x + 7)) / (x + 7)|

Simplifying further, we get:

lim(n→∞) |(2n + 3)(2n + 2)|

Since this limit is nonzero and finite, the ratio test tells us that the series converges for all values of x.

f'(x) = 4x - 1 and f(3) = 7, based on the given information and using calculus techniques to determine the equation of the tangent line and integrating the derivative.

To find f'(x), we can start by using the definition of the derivative. Since f'(-1) = 4, this means that the slope of the tangent line to the graph of f(x) at x = -1 is 4. We also know that f(-1) = -5, which gives us a point on the graph of f(x) at x = -1. Using these two pieces of information, we can set up the equation of the tangent line at x = -1.Using the point-slope form of a line, we have y - (-5) = 4(x - (-1)), which simplifies to y + 5 = 4(x + 1). Expanding and rearranging, we get y = 4x + 4 - 5, which simplifies to y = 4x - 1. This equation represents the tangent line to the graph of f(x) at x = -1.

To find f'(x), we need to determine the derivative of f(x). Since the tangent line represents the derivative at x = -1, we can conclude that f'(x) = 4x - 1.Now, to find f(3), we can use the derivative we just found. Integrating f'(x) = 4x - 1, we obtain f(x) = 2x^2 - x + C, where C is a constant. To determine the value of C, we use the given information f(-1) = -5. Substituting x = -1 and f(-1) = -5 into the equation, we get -5 = 2(-1)^2 - (-1) + C, which simplifies to -5 = 2 + 1 + C. Solving for C, we find C = -8.Thus, the equation of the function f(x) is f(x) = 2x^2 - x - 8. To find f(3), we substitute x = 3 into the equation, which gives us f(3) = 2(3)^2 - 3 - 8 = 2(9) - 3 - 8 = 18 - 3 - 8 = 7.

We need to find the partial derivatives of f(x, y, z) with respect to x, y, and z.To find the partial derivative of f(x, y, z) with respect to x (fx), we differentiate the function with respect to x while treating y and z as constants.

fx(x, y, z) = d/dx(3x^2 + 6y^2 + x^2)

Differentiating each term separately:

fx(x, y, z) = d/dx(3x^2) + d/dx(6y^2) + d/dx(x^2)

Applying the power rule of differentiation, where
d/dx(x^n) = nx^(n-1):

fx(x, y, z) = 6x + 0 + 2x

Simplifying:

fx(x, y, z) = 8x

Similarly, to find the partial derivatives fy(x, y, z) and fz(x, y, z), we differentiate the function with respect to y and z, respectively, while treating the other variables as constants.

fy(x, y, z) = d/dy(3x^2 + 6y^2 + x^2)

fy(x, y, z) = 0 + 12y + 0

fy(x, y, z) = 12y

fz(x, y, z) = d/dz(3x^2 + 6y^2 + x^2)

To evaluate the integral ∫[tex]x * e^(ex) * ax * 8x dx,[/tex] we can use integration by parts. Let's denote[tex]u = x and dv = e^(ex) * ax * 8x dx.[/tex]

Taking the derivative of u, we have du = dx, and integrating dv, we get:

[tex]∫e^(ex) * ax * 8x dx = 8a∫x * e^(ex) * x dx[/tex]

Using integration by parts formula, we have:

∫u dv = uv - ∫v du.

Applying this formula, we choos[tex]e u = x and dv = e^(ex) * ax * 8x dx. Then, du = dx and v = ∫e^(ex) * ax * 8x dx.[/tex]

Integrating v requires substitution. Let's substitute t = ex, then dt = ex dx. Rewriting v in terms of t, we have:

[tex]v = ∫e^t * ax * 8 * (1/t) dt= 8ax ∫e^t / t dt.[/tex]

The integral ∫e^t / t dt is known as the exponential integral function, denoted as Ei(t). Hence, we have:

[tex]v = 8ax * Ei(t).[/tex]

Returning to the original variables, we have:

[tex]v = 8ax * Ei(ex).[/tex]

Applying integration by parts formula:

[tex]∫x * e^(ex) * ax * 8x dx = uv - ∫v du= x * (8ax * Ei(ex)) - ∫(8ax * Ei(ex)) dx= 8ax^2 * Ei(ex) - ∫(8a * ex * Ei(ex)) dx.[/tex]

To evaluate the remaining integral, we can use substitution again. Let's substitute u = ex, then du = ex dx. The integral becomes:

∫(8a * ex * Ei(ex)) dx = 8a ∫(u * Ei(u)) du.

Integrating this requires a special function called the exponential integral, which is not expressible in elementary terms. Therefore, we cannot evaluate the integral further.

To check our result, we can differentiate the obtained antiderivative. Taking the derivative of 8ax^2 * Ei(ex) gives us the integrand back: x * e^(ex) * ax * 8x, confirming the correctness of the integration.

Hence, the evaluation of the integral is 8ax^2 * Ei(ex) + C, where C is the constant of integration.

To find the area of the region below the curve y = x^2 + 2x - 2 and above the line y = 5, we need to determine the intersection points of the two curves and then calculate the area between them.

Step 1: Find the intersection points. Set the two equations equal to each other: x^2 + 2x - 2 = 5. Rearrange the equation to bring it to the standard quadratic form: x^2 + 2x - 7 = 0. Solve this quadratic equation for x using factoring, completing the square, or the quadratic formula. Let's use the quadratic formula:x = (-2 ± √(2^2 - 41(-7))) / (2*1)

x = (-2 ± √(4 + 28)) / 2

x = (-2 ± √32) / 2

x = (-2 ± 4√2) / 2

x = -1 ± 2√2. So the two intersection points are: x = -1 + 2√2 and x = -1 - 2√2. Step 2: Calculate the area. To find the area between the two curves, we integrate the difference between the two curves with respect to x over the interval where they intersect.

The area can be calculated as follows: Area = ∫[a, b] (f(x) - g(x)) dx. In this case, f(x) represents the upper curve (y = x^2 + 2x - 2) and g(x) represents the lower curve (y = 5). Area = ∫[-1 - 2√2, -1 + 2√2] [(x^2 + 2x - 2) - 5] dx. Simplify the expression: Area = ∫[-1 - 2√2, -1 + 2√2] (x^2 + 2x - 7) dx. Integrate the expression: Area = [(1/3)x^3 + x^2 - 7x] evaluated from -1 - 2√2 to -1 + 2√2. Evaluate the expression at the upper and lower limits:Area = [(1/3)(-1 + 2√2)^3 + (-1 + 2√2)^2 - 7(-1 + 2√2)] - [(1/3)(-1 - 2√2)^3 + (-1 - 2√2)^2 - 7(-1 - 2√2)].

To write the quadratic function f(x) = 2x^2 + 16x - 29 in the form f(x) = a(x - n)^2 + k, we need to complete the square.

First, let's factor out the leading coefficient of 2 from the first two terms: f(x) = 2(x^2 + 8x) - 29 Next, we complete the square by adding and subtracting the square of half the coefficient of the x term (in this case, 8/2 = 4): f(x) = 2(x^2 + 8x + 4^2 - 4^2) - 29

Simplifying:

f(x) = 2(x^2 + 8x + 16 - 16) - 29

f(x) = 2((x + 4)^2 - 16) - 29

f(x) = 2(x + 4)^2 - 32 - 29

f(x) = 2(x + 4)^2 - 61

Now, we can see that a = 2, n = -4, and k = -61. Therefore, the quadratic function f(x) = 2x^2 + 16x - 29 can be written as f(x) = 2(x + 4)^2 - 61. The vertex of the graph occurs when x = -4, and plugging this value into the equation gives us:

f(-4) = 2(-4 + 4)^2 - 61

f(-4) = 2(0)^2 - 61

f(-4) = 0 - 61

f(-4) = -61

Hence, the vertex of the graph is (-4, -61).
