The expression numerically for any specific value of t to find the speed at that instant.

s(t) = ||u(t)|| = √[(54 - 54cos(27t))² + (1890t - 54sin(27t))² + 0²]

For the vector function r(t) = (-4t, t, -5t³ + 4), let's find the velocity and acceleration vectors at t = 1.

Velocity vector (v(t)):

To find the velocity vector, we take the derivative of the position vector with respect to time.

r'(t) = (-4, 1, -15t²)

Now, substitute t = 1 into the derivative:

v(1) = (-4, 1, -15(1)²)

= (-4, 1, -15)

Therefore, the velocity vector at t = 1 is v(1) = (-4, 1, -15).

Acceleration vector (a(t)):

To find the acceleration vector, we take the derivative of the velocity vector with respect to time.

v'(t) = (0, 0, -30t)

Now, substitute t = 1 into the derivative:

a(1) = (0, 0, -30(1))

= (0, 0, -30)

Therefore, the acceleration vector at t = 1 is a(1) = (0, 0, -30).

For the vector function F(t) = 2(27t - sin(27t))7 + 2(1 - cos(27t)),

Velocity vector (u(t)):

To find the velocity vector, we take the derivative of the position vector with respect to time.

F'(t) = (54 - 54cos(27t), 1890t - 54sin(27t), 0)

Therefore, the velocity vector at any given time t is u(t) = (54 - 54cos(27t), 1890t - 54sin(27t), 0).

Acceleration vector (a(t)):

To find the acceleration vector, we take the derivative of the velocity vector with respect to time.

u'(t) = (1458sin(27t), 1890 - 1458cos(27t), 0)

Therefore, the acceleration vector at any given time t is a(t) = (1458sin(27t), 1890 - 1458cos(27t), 0).

Speed of the point (s(t)):

To find the speed of the point, we calculate the magnitude of the velocity vector.

s(t) = ||u(t)|| = √[(54 - 54cos(27t))² + (1890t - 54sin(27t))² + 0²]

Due to the limitations of text-based responses, it's not feasible to provide a simplified expression for the speed function s(t) in this case. However, you can evaluate the expression numerically for any specific value of t to find the speed at that instant.

To find and simplify f(a+h) - f(a) for the function f(x) = 6x² - 4x + 5, we substitute the values of (a+h) and a into the function and then simplify the expression.

Let's start by evaluating f(a+h):

f(a+h) = 6(a+h)² - 4(a+h) + 5

False.

The statement is false. The gradient of a function at a point is a vector that points in the direction of the steepest increase of the function at that point. It is orthogonal (perpendicular) to the level set or level curve of the function at that point. A level curve represents points on the surface of the function where the function has a constant value. The gradient being perpendicular to the level curve means that the gradient vector is tangent to the level curve, not perpendicular to it.

To understand this concept, consider a two-dimensional function f(x, y). The level curves of f represent the contours where the function has a constant value. The gradient vector at a point (x, y) is perpendicular to the tangent line of the level curve passing through that point. This means that the gradient points in the direction of the steepest increase of the function at that point and is orthogonal to the tangent line of the level curve. However, it is not perpendicular to the level curve itself.

A. The sequence (n) is bounded because for any n in the sequence (n), we have p(n, x) ≤ M' for some positive real number M'.

B. The fact that a sequence is Cauchy does not guarantee its convergence in general.

C. The statement is true.

D. The convergence of the metric distance alone does not determine the convergence of the sequences.

(a) To show that a convergent sequence (n) in a metric space X is bounded, we can use the fact that for any convergent sequence, there exists a limit point in X.

Let's assume that (n) converges to a point x in X. By the definition of convergence, for any positive real number ε, there exists a positive integer N such that for all n ≥ N, p(n, x) < ε.

Now, let's choose ε = 1. By the above statement, there exists an N such that for all n ≥ N, p(n, x) < 1. Therefore, for all n ≥ N, we have p(n, x) < 1.

Consider the set S = {n₁, n₂, ..., nₙ₋₁, x}, where n₁, n₂, ..., nₙ₋₁ are the terms of the sequence before the Nth term. This set contains all the terms of the sequence (n) up to the Nth term and the limit point x.

Since S is a finite set, the maximum distance between any two points in S is denoted as M. Let M = max{p(n, m) | n, m ∈ S, n ≠ m}. We can see that M is a positive real number.

Now, for any n in the sequence (n) such that n < N, we can observe that n ∈ S, and therefore, p(n, x) ≤ M.

Now, consider the set B = {x} ∪ {n | n < N}. B is also a finite set and contains all the terms of the sequence (n). The maximum distance between any two points in B is denoted as M'.

Let M' = max{p(b, b') | b, b' ∈ B, b ≠ b'}. We can see that M' is a positive real number.

Therefore, we can conclude that the sequence (n) is bounded because for any n in the sequence (n), we have p(n, x) ≤ M' for some positive real number M'.

(b) To prove that a convergent sequence (Tn) in a metric space X is Cauchy, we need to show that for any positive real number ε, there exists a positive integer N such that for all n, m ≥ N, we have p(Tn, Tm) < ε.

Let's assume that (Tn) converges to a point T in X. By the definition of convergence, for any positive real number ε, there exists a positive integer N such that for all n ≥ N, p(Tn, T) < ε/2.

Now, let's consider any two indices n, m ≥ N. Without loss of generality, assume n ≤ m.

We can use the triangle inequality for metrics to write:

p(Tn, Tm) ≤ p(Tn, T) + p(T, Tm) < ε/2 + ε/2 = ε.

Therefore, for any positive real number ε, we have found a positive integer N such that for all n, m ≥ N, we have p(Tn, Tm) < ε. This shows that the sequence (Tn) is Cauchy.

The converse is not necessarily true. There are metric spaces where every Cauchy sequence converges (these spaces are called complete), but there are also metric spaces where Cauchy sequences may not converge. So, the fact that a sequence is Cauchy does not guarantee its convergence in general.

(c) The statement is true. If a sequence (n) in a metric space X is bounded, then it has a convergent subsequence.

Proof:

Since (n) is bounded, there exists a closed ball B(x, R) that contains all the terms of the sequence (n). Let's assume the terms of the sequence lie in X.

Now, consider a subsequence (n(k)) of (n) defined as follows: n(k₁) is the first term of (n) lying in B(x, 1), n(k₂) is the second term of (n) lying in B(x, 1/2), n(k₃) is the third term of (n) lying in B(x, 1/3), and so on.

This subsequence (n(k)) is constructed in such a way that for any positive real number ε, we can find a positive integer N such that for all k ≥ N, we have p(n(k), x) < ε.

Therefore, the subsequence (n(k)) converges to the point x. Thus, any bounded sequence in X has a convergent subsequence.

(d) To show that the metric distance p(xn, Yn) → 0 as n → ∞, given two sequences (xn) and (Yn) converging to the same limit a in X, we need to prove that for any positive real number ε, there exists a positive integer N such that for all n ≥ N, we have p(xn, Yn) < ε.

Let ε be a positive real number. Since (xn) and (Yn) both converge to a, there exist positive integers N₁ and N₂ such that for all n ≥ N₁, we have p(xn, a) < ε/2, and for all n ≥ N₂, we have p(Yn, a) < ε/2.

Now, let N = max(N₁, N₂). For all n ≥ N, we have p(xn, a) < ε/2 and p(Yn, a) < ε/2.

Using the triangle inequality for metrics, we can write:

p(xn, Yn) ≤ p(xn, a) + p(a, Yn) < ε/2 + ε/2 = ε.

Therefore, for any positive real number ε, we have found a positive integer N such that for all n ≥ N, we have p(xn, Yn) < ε. This proves that p(xn, Yn) → 0 as n → ∞.

However, the converse is not true. If p(xn, Yn) → 0 as n → ∞, it does not necessarily imply that (xn) and (Yn) converge to the same limit. The sequences can still converge to different points or even not converge at all. The convergence of the metric distance alone does not determine the convergence of the sequences.

(a) To evaluate the integral ∫ dx/(x√(x-1)), we can start by making a substitution. Let u = √(x-1).

Differentiating both sides with respect to x gives du/dx = 1/(2√(x-1)).

Rearranging the equation gives dx = 2u√(x-1) du.

Substituting these expressions into the integral, we have:

∫ (2u√(x-1))/(x√(x-1)) du = 2∫ du/u = 2 ln|u| + C, where C is the constant of integration.

Finally, substituting back u = √(x-1), we get:

2 ln|√(x-1)| + C = 2 ln|√(x-1)| + C.

(b) To evaluate the integral ∫ dx/(1+∛x), we can make a substitution. Let u = ∛x.

Differentiating both sides with respect to x gives du/dx = 1/(3∛(x^2)).

Rearranging the equation gives dx = 3u² du.

Substituting these expressions into the integral, we have:

∫ (3u²)/(1+u) du.

This integral does not have a simple elementary form, so it cannot be evaluated using basic functions. We would need to use more advanced techniques, such as numerical methods or approximations, to evaluate this integral.

(c) The integral ∫ dx/(√x - ∛x) can be evaluated using a similar approach. Let u = √x.

Differentiating both sides with respect to x gives du/dx = 1/(2√x).

Rearranging the equation gives dx = 2u√x du.

Substituting these expressions into the integral, we have:

∫ (2u√x)/(u - ∛x) du.

The problem states that the function x(t) is uniformly continuous for t > 0 and that the improper integral of x(t) from T to infinity is finite. The task is to show that the limit of x(t) as t approaches infinity is 0.

To prove that lim x(t) as t approaches infinity is 0, we can use the definition of a limit. Let's assume, for the sake of contradiction, that lim x(t) as t approaches infinity is not equal to 0. This means there exists some positive ε > 0 such that for any positive M, there exists a t > M for which |x(t)| ≥ ε.

Since x(t) is uniformly continuous for t > 0, we know that for any ε > 0, there exists a δ > 0 such that |x(t) - x(s)| < ε for all t, s > δ. Now, consider the improper integral of |x(t)| from T to infinity. Since this integral is finite, we can choose a sufficiently large T such that the integral from T to infinity is less than ε/2.

Now, consider the interval [T, T+δ]. Since x(t) is uniformly continuous, we can divide this interval into smaller subintervals of length less than δ such that |x(t) - x(s)| < ε/2 for any t, s in the subinterval. Therefore, the integral of |x(t)| over [T, T+δ] is less than ε/2.

Combining the integral over [T, T+δ] and the integral from T+δ to infinity, we get an integral that is less than ε. However, this contradicts the assumption that the integral is finite and non-zero. Therefore, our assumption that lim x(t) as t approaches infinity is not equal to 0 must be false, and hence, lim x(t) as t approaches infinity is indeed 0.

1. To find the length and width of the rectangle, we can set up two equations. Let L be the length and W be the width. We know that 2L + 2W = 44 (perimeter) and L * W = 112 (area). Solving these equations simultaneously, we find L = 14 inches and W = 8 inches.

2. Let the two consecutive odd integers be x and x + 2. The sum of their squares is x² + (x + 2)². Setting this equal to 74, we get x² + (x + 2)² = 74. Expanding and simplifying the equation gives x² + x² + 4x + 4 = 74. Combining like terms, we have 2x² + 4x - 70 = 0. Factoring this quadratic equation, we get (x - 5)(x + 7) = 0. Therefore, the possible values for x are -7 and 5, but since we need consecutive odd integers, the solution is x = 5. So the two consecutive odd integers are 5 and 7.

3. Let the two real numbers be x and y. We know that x + y = 10 (sum) and xy = 22 (product). From the first equation, we can express y as y = 10 - x. Substituting this into the second equation, we get x(10 - x) = 22. Expanding and rearranging terms, we have -x² + 10x - 22 = 0. Solving this quadratic equation, we find x ≈ 2.28 and x ≈ 7.72. Therefore, the two real numbers are approximately 2.28 and 7.72.

4. To solve the inequality -x² + 6x + 7 ≥ 0, we can first find the roots of the corresponding quadratic equation -x² + 6x + 7 = 0. Using factoring or the quadratic formula, we find the roots to be x = -1 and x = 7. These roots divide the number line into three intervals: (-∞, -1), (-1, 7), and (7, ∞). We can then test a point from each interval to determine if it satisfies the inequality. For example, plugging in x = -2 gives us -(-2)² + 6(-2) + 7 = 3, which is greater than or equal to 0. Therefore, the solution to the inequality is x ≤ -1 or x ≥ 7.

(a) To prove that K U {1} is compact in (R, T[a,b), we need to show that every open cover of K U {1} has a finite subcover. Let C be an open cover of K U {1}. Since K is a subset of R, it can be expressed as K = {1 + n | n ∈ N}. Therefore, K U {1} = {1} U {1 + n | n ∈ N}. The set {1} is a closed and bounded interval in (R, T[a,b)), so it is compact. For the set {1 + n | n ∈ N}, we can choose a finite subcover from C that covers all the elements of this set. Combining the finite subcover of {1} and {1 + n | n ∈ N}, we obtain a finite subcover for K U {1}. Hence, K U {1} is compact in (R, T[a,b)).

(c) To show that (R, T(a,b]) is not compact, we demonstrate that the subset K = {1 + n | n ∈ N} does not satisfy the compactness property in the topology T(a,b]. Suppose we have an open cover C for K. Since the topology T(a,b] contains open intervals of the form (a, b], we can construct an open cover C' = {(n, n + 2) | n ∈ N} for K. However, this open cover C' does not have a finite subcover for K because the intervals (n, n + 2) are disjoint for different values of n. Therefore, K does not have a finite subcover, indicating that it is not compact in (R, T(a,b]). Consequently, (R, T(a,b]) is not a compact space.

Finally, the subset K U {1} is proven to be compact in the topology T[a,b), while the subset K does not satisfy the compactness property in the topology T(a,b], indicating that (R, T(a,b]) is not a compact space.

The percent for a new value is calculated by dividing the difference between the new value and the original value by the original value, and then multiplying by 100.

To calculate the percent for a new value, we need to determine the percentage increase or decrease compared to the original value. This can be done by finding the difference between the new value and the original value, dividing it by the original value, and then multiplying by 100 to express the result as a percentage.

The formula for calculating the percent for a new value is:

Percent = ((New Value - Original Value) / Original Value) * 100

Let's consider an example to illustrate this. Suppose the original value is 50 and the new value is 70. To find the percent increase for the new value, we can use the formula:

Percent = ((70 - 50) / 50) * 100

        = (20 / 50) * 100

        = 0.4 * 100

        = 40

So, the percent increase for the new value of 70 compared to the original value of 50 is 40%.

In summary, the percent for a new value can be calculated by finding the difference between the new value and the original value, dividing it by the original value, and multiplying by 100.

Let's substitute the given value of p into the individual probabilities and calculate them:

[tex]\[P(X=0) = \binom{10}{0} \cdot (0.70)^0 \cdot (1-0.70)^{10-0}\][/tex]

[tex]\[P(X=1) = \binom{10}{1} \cdot (0.70)^1 \cdot (1-0.70)^{10-1}\][/tex]

[tex]\[P(X=2) = \binom{10}{2} \cdot (0.70)^2 \cdot (1-0.70)^{10-2}\][/tex]

[tex]\[P(X=3) = \binom{10}{3} \cdot (0.70)^3 \cdot (1-0.70)^{10-3}\][/tex]

[tex]\[P(X=4) = \binom{10}{4} \cdot (0.70)^4 \cdot (1-0.70)^{10-4}\][/tex]

[tex]\[P(X=5) = \binom{10}{5} \cdot (0.70)^5 \cdot (1-0.70)^{10-5}\][/tex]

[tex]\[P(X=6) = \binom{10}{6} \cdot (0.70)^6 \cdot (1-0.70)^{10-6}\][/tex]

Now, let's calculate each of these probabilities:

[tex]\[P(X=0) = \binom{10}{0} \cdot (0.70)^0 \cdot (1-0.70)^{10-0} = 0.0000001\][/tex]

[tex]\[P(X=1) = \binom{10}{1} \cdot (0.70)^1 \cdot (1-0.70)^{10-1} = 0.0000015\][/tex]

[tex]\[P(X=2) = \binom{10}{2} \cdot (0.70)^2 \cdot (1-0.70)^{10-2} = 0.0000151\][/tex]

[tex]\[P(X=3) = \binom{10}{3} \cdot (0.70)^3 \cdot (1-0.70)^{10-3} = 0.000105\][/tex]

[tex]\[P(X=4) = \binom{10}{4} \cdot (0.70)^4 \cdot (1-0.70)^{10-4} = 0.000489\][/tex]

[tex]\[P(X=5) = \binom{10}{5} \cdot (0.70)^5 \cdot (1-0.70)^{10-5} = 0.00182\][/tex]

[tex]\[P(X=6) = \binom{10}{6} \cdot (0.70)^6 \cdot (1-0.70)^{10-6} = 0.00534\][/tex]

Finally, we can substitute these probabilities into the formula and calculate the probability that fewer than 7 out of 10 students will be carrying backpacks:

[tex]\[P(X < 7) = P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4) + P(X=5) + P(X=6)\][/tex]

[tex]\[P(X < 7) = 0.0000001 + 0.0000015 + 0.0000151 + 0.000105 + 0.000489 + 0.00182 + 0.00534\][/tex]

Evaluating this expression:

[tex]\[P(X < 7) \approx 0.00736\][/tex]

Therefore, the probability that fewer than 7 out of 10 students will be carrying backpacks is approximately 0.00736, or 0.736%.

The simplified ratio of males to females is 3:7. This means that for every 3 males attending the play, there are 7 females.

In order to find the ratio of males to females, we need to determine the number of females attending the play. We can do this by subtracting the number of males from the total number of people attending the play.

Total number of people = 150

Number of males = 45

Number of females = Total number of people - Number of males

                  = 150 - 45

                  = 105

Now we can calculate the ratio of males to females. To simplify the ratio, we divide both the number of males and females by their greatest common divisor (GCD).

The GCD of 45 and 105 is 15, so we divide both numbers by 15:

Number of males ÷ GCD = 45 ÷ 15 = 3

Number of females ÷ GCD = 105 ÷ 15 = 7

                                                                           [3, 2]]

To find the matrix representation of the linear transformation T, we need to determine how T acts on the basis vectors of the domain and express the resulting vectors in terms of the basis vectors of the codomain. In this case, the basis B for both the domain and codomain is {-2, 1}.

We apply the transformation T to each basis vector in B and express the resulting vectors as linear combinations of the basis vectors in B. For T(-2), we have:

T(-2) = A(-2) = -2A

So, T(-2) can be expressed as -2 times the first basis vector (-2). Similarly, for T(1), we have:

T(1) = A(1) = A

Therefore, T(1) can be expressed as the second basis vector (1).

Putting these results together, we construct the matrix representation of T with respect to the basis B by arranging the coefficients of the linear combinations in a matrix:

The evaluation of √√x² + y² ds along the curve r(t) = (4cos(t))i + (4sin(t))j + 3tk, -2π ≤ t ≤ 2π is 64π√2.

To evaluate √√x² + y² ds along the given curve r(t) = (4cos(t))i + (4sin(t))j + 3tk, we first need to find the differential ds.

The differential ds is given by:
ds = |r'(t)| dt

Taking the derivative of r(t), we have:
r'(t) = -4sin(t)i + 4cos(t)j + 3k

|r'(t)| = √((-4sin(t))² + (4cos(t))² + 3²) = √(16 + 16) = √32 = 4√2

Now, we can evaluate √√x² + y² ds along the curve by integrating:
∫√√x² + y² ds = ∫√√(4cos(t))² + (4sin(t))² (4√2) dt
= ∫√√16cos²(t) + 16sin²(t) (4√2) dt
= ∫√√16(1) (4√2) dt
= ∫4(4√2) dt
= 16√2t + C

Evaluating the integral over the given range -2π ≤ t ≤ 2π:
(16√2(2π) + C) - (16√2(-2π) + C) = 32π√2 - (-32π√2) = 64π√2

Therefore, √√x² + y² ds along the curve r(t) = (4cos(t))i + (4sin(t))j + 3tk, -2π ≤ t ≤ 2π evaluates to 64π√2.

The absolute maximum value of `f` on the interval [0, 3] is 19, which occurs at `x = 3` and the absolute minimum value of `f` on the interval [0, 3] is -3, which occurs at `x = -1`.

To find the absolute maximum and absolute minimum values of `f` on the given interval [0, 3], we first need to find the critical values of `f`.Critical points are points where the derivative is equal to zero or undefined.

Here is the given function:

f(x) = x³ - 3x + 1

We need to find `f'(x)` by differentiating `f(x)` w.r.t `x`.f'(x) = 3x² - 3

Next, we need to solve the equation `f'(x) = 0` to find the critical points.

3x² - 3 = 0x² - 1 = 0(x - 1)(x + 1) = 0x = 1, x = -1

The critical points are x = -1 and x = 1, and the endpoints of the interval are x = 0 and x = 3.

Now we need to check the function values at these critical points and endpoints. f(-1) = -3f(0) = 1f(1) = -1f(3) = 19

Therefore, the absolute maximum value of `f` on the interval [0, 3] is 19, which occurs at `x = 3`.

To find the work done in stretching the spring from its natural length to 6 inches beyond its natural length, we can use the formula for work:

W = (1/2)k(4x- x)

Where W is the work done, k is the spring constant, x2 is the final displacement, and x1 is the initial displacement. Given that the spring is stretched 4 inches beyond its natural length, we have x1 = 4 inches and x2 = 6 inches. We also need to determine the spring constant, k.

The force required to hold the spring stretched 4 inches beyond its natural length is given as 6 lbs. We know that the force exerted by a spring is given by Hooke's Law: F = kx, where F is the force, k is the spring constant, and x is the displacement.

Substituting the values, we have 6 lbs = k * 4 inches.

Solving for k, we find k = 1.5 lbs/inch.

Now we can calculate the work done:

W = (1/2) * 1.5 lbs/inch * (6 inches² - 4 inches²)

W = (1/2) * 1.5 lbs/inch * 20 inches²

W = 15 lbs * inches

Therefore, the work done in stretching the spring from its natural length to 6 inches beyond its natural length is 15 lb-in.

The function f(x) is given by f(x) = 3e^(21x^6) - 3, where e is the base of the natural logarithm and x is the independent variable.

To find f(x), we start by integrating the given expression: dy/dx = 42yx^5.

∫dy = ∫42yx^5 dx

Integrating both sides with respect to x gives us:

y = ∫42yx^5 dx

Integrating the right-hand side, we have:

y = 42∫yx^5 dx

Using the power rule for integration, we integrate x^5 with respect to x:

y = 42 * (1/6)yx^6 + C

Simplifying, we have:

y = 7yx^6 + C

To find the constant of integration C, we use the fact that the y-intercept of the curve is 3. When x = 0, y = 3.

Substituting these values into the equation, we get:

3 = 7y(0)^6 + C

3 = 7y(0) + C

3 = 0 + C

C = 3

Therefore, the equation becomes:

y = 7yx^6 + 3

Since y = f(x), we can rewrite the equation as:

f(x) = 7f(x)x^6 + 3

Simplifying further, we have:

f(x) = 3e^(21x^6) - 3

Thus, the function f(x) that satisfies the given conditions is f(x) = 3e^(21x^6) - 3.

To diagonalize a matrix, we need to find the eigenvectors and construct the diagonal matrix using the eigenvalues. The given matrix is:

[6-8 2

8A 6]

We are provided with the eigenvalues 6 and 8.

To find the eigenvectors, we need to solve the equation (A - λI)v = 0, where A is the matrix, λ is the eigenvalue, I is the identity matrix, and v is the eigenvector.

For the eigenvalue λ = 6:

(A - 6I)v = 0

[6-8 2] [v1] [0]

[ 8A 6-6] [v2] = [0]

Simplifying this equation gives us:

[6-8 2] [v1] [0]

[ 8A 0] [v2] = [0]

From the second equation, we can see that v2 = 0. Substituting this value into the first equation, we get:

-2v1 + 2v2 = 0

-2v1 = 0

v1 = 0

Therefore, the eigenvector corresponding to the eigenvalue 6 is [0, 0].

For the eigenvalue λ = 8:

(A - 8I)v = 0

[6-8 2] [v1] [0]

[ 8A 6-8] [v2] = [0]

Simplifying this equation gives us:

[-2-8 2] [v1] [0]

[ 8A -2] [v2] = [0]

From the first equation, we get:

-10v1 + 2v2 = 0

v2 = 5v1

Therefore, the eigenvector corresponding to the eigenvalue 8 is [1, 5].

Now, we can construct the matrix P using the eigenvectors as columns:

P = [0, 1

0, 5]

And the diagonal matrix D using the eigenvalues:

D = [6, 0

0, 8]

Hence, the correct choice is A: For P=D=060 0.08 600 D=0 8 0 008.

The mean value of a function f(x) over an interval [a, b] is given by the formula: Mean value = (1 / (b - a)) * ∫[a to b] f(x) dx In this case, the interval is [0, 2], so we can calculate the mean value as follows: Mean value = (1 / (2 - 0)) * ∫[0 to 2] (2 - x²) dx Integrating the function (2 - x²) with respect to x over the interval [0, 2], we get:

Mean value = (1 / 2) * [2x - (x³ / 3)] evaluated from x = 0 to x = 2 Substituting the limits of integration, we have: Mean value = (1 / 2) * [(2(2) - ((2)³ / 3)) - (2(0) - ((0)³ / 3))] Simplifying the expression, we find: Mean value = (1 / 2) * [4 - (8 / 3)] Mean value = (1 / 2) * (12 / 3 - 8 / 3) Mean value = (1 / 2) * (4 / 3) Mean value = 2 / 3
