If two events A and B are independent, the following statements must be true. If two events A and B are independent, then the occurrence of one event does not affect the occurrence of the other event.

In other words, the probability of one event does not influence the probability of the other event. Based on this definition, we can analyze each statement and determine which one(s) must be true.
a. P(AIB)=P(A): This statement is true for independent events. It means that the probability of event A occurring given that event B has occurred is equal to the probability of event A occurring. Therefore, statement a is correct.
b. P(A or B) = P(A)P(B): This statement is not always true for independent events. It is only true if events A and B are also mutually exclusive. In other words, if events A and B cannot occur at the same time. Therefore, statement b is incorrect.
c. P(A/B)-P(B): This statement does not make sense for independent events since the probability of event A does not depend on the occurrence of event B. Therefore, statement c is incorrect.

To sketch the graphs of the corresponding solutions in the ty-plane using the qualitative theory of autonomous differential equations, we can analyze the behavior of the given autonomous equation: y = y³ - 3y.

First, let's find the critical points by setting the equation equal to zero and solving for y:y³ - 3y = 0

y(y² - 3) = 0

From this, we can see that the critical points are y = 0 and y = ±√3.

Next, let's determine the behavior of the solutions around these critical points by examining the sign of the derivative dy/dt.

Taking the derivative of the equation with respect to t, we get:dy/dt = (3y² - 3)dy/dt

Now, we can analyze the sign of dy/dt based on the value of y:

1. which means the solutions will decrease as t increases.

2. For -√3 < y < 0, dy/dt > 0, indicating that the solutions will increase as t increases.3. For 0 < y < √3, dy/dt > 0, implying that the solutions will also increase as t increases.

4. For y > √3, dy/dt < 0, meaning the solutions will decrease as t increases.

Now, let's sketch the graphs of the solutions based on the initial conditions provided:

a) y(0) = -3:With this initial condition, the solution starts at y = -3, which is below -√3. From our analysis, we know that the solution will decrease as t increases, so the graph will curve downwards and approach the critical point y = -√3 as t goes to infinity.

b) y(0) = -1/2:

With this initial condition, the solution starts at y = -1/2, which is between -√3 and 0. According to our analysis, the solution will increase as t increases. The graph will curve upwards and approach the critical point y = √3 as t goes to infinity.

c) y(0) = 3/2:With this initial condition, the solution starts at y = 3/2, which is between 0 and √3. As per our analysis, the solution will also increase as t increases. The graph will curve upwards and approach the critical point y = √3 as t goes to infinity.

d) y(0) = 3:

With this initial condition, the solution starts at y = 3, which is above √3. From our analysis, we know that the solution will decrease as t increases. The graph will curve downwards and approach the critical point y = √3 as t goes to infinity.

In summary, the graphs of the corresponding solutions in the ty-plane will have curves that approach the critical points at y = -√3 and y = √3, and their behavior will depend on the initial conditions provided.

Therefore, the integral ∫2^(3 – 2x) dx, with the substitution u = 2^(3 – 2x), evaluates to:

(-1 / (2(ln 2))) ln (8) + (1 / ln 2) x + C, where C is the constant of integration.

To evaluate the integral ∫2^(3 – 2x) dx using the substitution u = 2^(3 – 2x), let's proceed with the following steps:

Let u = 2^(3 – 2x)

Differentiate both sides with respect to x to find du/dx:

du/dx = d/dx [2^(3 – 2x)]

To simplify the derivative, we can use the chain rule. The derivative of 2^x is given by (ln 2) * 2^x. Applying the chain rule, we have:

du/dx = d/dx [2^(3 – 2x)] = (ln 2) * 2^(3 – 2x) * (-2) = -2(ln 2) * 2^(3 – 2x)

Now, we can solve for dx in terms of du:

du = -2(ln 2) * 2^(3 – 2x) dx

dx = -du / [2(ln 2) * 2^(3 – 2x)]

Substituting this value of dx and u = 2^(3 – 2x) into the integral, we have:

∫2^(3 – 2x) dx = ∫-du / [2(ln 2) * u]

              = -1 / (2(ln 2)) ∫du / u

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

Finally, substituting u = 2^(3 – 2x) back into the expression:

∫2^(3 – 2x) dx = (-1 / (2(ln 2))) ln |2^(3 – 2x)| + C

              = (-1 / (2(ln 2))) ln |2^(3) / 2^(2x)| + C

              = (-1 / (2(ln 2))) ln |8 / 2^(2x)| + C

              = (-1 / (2(ln 2))) ln (8) - (-1 / (2(ln 2))) ln |2^(2x)| + C

              = (-1 / (2(ln 2))) ln (8) - (-1 / (2(ln 2))) (2x ln 2) + C

The vector equation of the line passing through the points A(0, 0, 0) and B(3, 3, -1), using the equation x = p + tv, where p = 0 and v = OB, is:r = p + tv

The vector equation x = p + tv represents a line in three-dimensional space, where r is a position vector on the line, p is a position vector of a point on the line, t is a scalar parameter, and v is the direction vector of the line.

In this case, we are given point A(0, 0, 0) as the origin and point B(3, 3, -1) as the second point on the line. To find the direction vector v, we can calculate OB (vector OB = OB₁i + OB₂j + OB₃k) by subtracting the coordinates of point A from the coordinates of point B: OB = (3 - 0)i + (3 - 0)j + (-1 - 0)k = 3i + 3j - k.

Since p = 0 and v = OB, we can substitute these values into the vector equation to obtain r = 0 + t(3i + 3j - k), which simplifies to r = 3ti + 3tj - tk. Thus, the vector equation of the line is r = 3ti + 3tj - tk.

Additionally, we can write the parametric equations of the line by separating the components of r: x = 3t, y = 3t, and z = -t. These equations provide a way to express the coordinates of any point on the line using the parameter t.

Therefore, the line passing through points A(0, 0, 0) and B(3, 3, -1) can be represented by the vector equation r = p + tv, where p = 0 and v = OB.

The determinant of the given matrix using cofactor expansion along the first row and first column is 0.

To compute the determinant of the matrix using cofactor expansion along the first row, we multiply each element of the first row by its cofactor and sum the results. The cofactor of each element is determined by the sign (-1)^(i+j) multiplied by the determinant of the submatrix obtained by removing the row and column containing that element. In this case, the first row elements are 1, 2, and 3. The cofactor of 1 is 5*(-1)^(2+2) = 5, the cofactor of 2 is 6*(-1)^(2+3) = -6, and the cofactor of 3 is 0*(-1)^(2+4) = 0. Therefore, the determinant using cofactor expansion along the first row is 1*5 + 2*(-6) + 3*0 = 0.

Similarly, to compute the determinant using cofactor expansion along the first column, we multiply each element of the first column by its cofactor and sum the results. The cofactor of each element is determined using the same method as above. The first column elements are 1, 4, and 7. The cofactor of 1 is 5*(-1)^(2+2) = 5, the cofactor of 4 is 9*(-1)^(3+2) = -9, and the cofactor of 7 is 0*(-1)^(3+3) = 0.

There are no local minimum values, inflection points, or intervals of concavity. The graph of f(x) will resemble an inverted parabola opening downwards, with a maximum point at x = 1/16 and a y-value of -4.

To analyze the function f(x) = x - 8x^2 - 4, we will perform the following steps:

a) Find the intervals on which f is increasing or decreasing:

To determine the intervals of increasing and decreasing, we need to analyze the sign of the derivative of f(x).

First, let's find the derivative of f(x):

f'(x) = 1 - 16x

To find the intervals of increasing and decreasing, we set f'(x) = 0 and solve for x:

1 - 16x = 0

16x = 1

x = 1/16

The critical point is x = 1/16.

Now, we analyze the sign of f'(x) in different intervals:

For x < 1/16: Choose x = 0, f'(0) = 1 - 0 = 1 (positive)

For x > 1/16: Choose x = 1, f'(1) = 1 - 16 = -15 (negative)

Therefore, f(x) is increasing on the interval (-∞, 1/16) and decreasing on the interval (1/16, ∞).

b) Find the local maximum and minimum values of f(x):

To find the local maximum and minimum values, we need to analyze the critical points and the endpoints of the given interval.

At the critical point x = 1/16, we can evaluate the function:

f(1/16) = (1/16) - 8(1/16)^2 - 4 = 1/16 - 1/128 - 4 = -4 - 1/128

Since the function is decreasing on the interval (1/16, ∞), the value at x = 1/16 will be a local maximum.

As for the endpoints, we consider f(0) and f(∞):

f(0) = 0 - 8(0)^2 - 4 = -4

As x approaches ∞, f(x) approaches -∞.

Therefore, the local maximum value is -4 at x = 1/16, and there are no local minimum values.

c) Find the intervals of concavity and the inflection points:

To find the intervals of concavity and the inflection points, we need to analyze the second derivative of f(x).

The second derivative of f(x) can be found by differentiating f'(x):

f''(x) = -16

Since the second derivative is a constant (-16), it does not change sign. Thus, there are no inflection points and no intervals of concavity.

d) Sketch the graph:

Based on the information obtained, we can sketch a rough graph of the function f(x):

The function is increasing on the interval (-∞, 1/16) and decreasing on the interval (1/16, ∞).

There is a local maximum at x = 1/16 with a value of -4.

The series is given by the expression ∑[infinity] 3(−1)nnxn, n = 1. The task is to find the radius of convergence, R, and the interval of convergence, I, for the series.

To find the radius of convergence, we can use the ratio test. Let's apply the ratio test to the series:

lim(n→∞) [tex]|\frac{(3(-1)^{(n+1)} * (n+1) * x^{(n+1)}}{ (3(-1)^n * n * x^n)} |[/tex]

Simplifying the expression, we get:

lim(n→∞) [tex]|\frac{(3(-1)^{(n+1)} * (n+1) * x^{(n+1)}}{ (3(-1)^n * n * x^n)} |[/tex]

= lim(n→∞) |(3 * (n+1) * x) / (n * x)|

= lim(n→∞) |3 * (n+1) / n|

= 3.

For the series to converge, the ratio should be less than 1. Therefore, |3| < 1, which is not true. Hence, the series diverges for all values of x. Consequently, the radius of convergence, R, is 0.

Since the series diverges for all x, the interval of convergence, I, is empty, represented by the notation I = {}.

The Taylor series for the function f(x) = 1/(1-2x), centered at c = 3 the interval of convergence is (-1/2, 1/2).

Let's find the Taylor series centered at c = 3 for the function f(x) = 1/(1-2x).

To find the Taylor series, we need to compute the derivatives of the function and evaluate them at the center (c = 3).

The general formula for the nth derivative of f(x) is given by:[tex]f^{n}(x) = (n!/(1-2x)^{n+1})[/tex]

where n! denotes the factorial of n.

Step 1: Compute the derivatives of f(x):

f'(x) = ([tex]1!/(1-2x)^{1+1}[/tex])

f''(x) = ([tex]2!/(1-2x)^{2+1}[/tex])

f'''(x) = ([tex]3!/(1-2x)^{3+1}[/tex])

Step 2: Evaluate the derivatives at x = 3:

f'(3) = ([tex]1!/(1-2(3))^{1+1}[/tex])

f''(3) = ([tex]2!/(1-2(3))^{2+1}[/tex])

f'''(3) = ([tex]3!/(1-2(3))^{3+1}[/tex])

Step 3: Simplify the expressions obtained from step 2:

f'(3) = 1/(-11)

f''(3) = 2/(-11)²

f'''(3) = 6/(-11)³

Step 4: Write the Taylor series using the simplified expressions from step 3:

f(x) = f(3) + f'(3)(x-3) + f''(3)(x-3)² + f'''(3)(x-3)³ + ...

Substituting the simplified expressions:

f(x) = 1 + (1/(-11))(x-3) + (2/(-11)²)(x-3)² + (6/(-11)³)(x-3)³ + ...

Step 5: Determine the interval of convergence.

The interval of convergence for a Taylor series can be determined by analyzing the function's convergence properties. In this case, the function f(x) = 1/(1-2x) has a singularity at x = 1/2. Therefore, the interval of convergence for the Taylor series centered at c = 3 will be the interval (-1/2, 1/2), excluding the endpoints.

To summarize, the Taylor series for the function f(x) = 1/(1-2x), centered at c = 3, is given by:

f(x) = 1 + (1/(-11))(x-3) + (2/(-11)²)(x-3)² + (6/(-11)³)(x-3)³ + ...

The interval of convergence is (-1/2, 1/2).

tangent vector

, s is the arc length parameter, and t is the parameter of the curve.

To find the curvature, we first need to compute the unit tangent vector T. The unit tangent vector T is given by T = dr/ds, where dr/ds is the derivative of the

vector function

r(t) with respect to the arc length parameter s. Since we are not given the arc

length

parameter, we need to find it first.

To find the arc length parameter s, we integrate the

magnitude

of the

derivative

of r(t) with respect to t. In this case, r(t) = (1, -1), so dr/dt = (0, 0), and the magnitude of dr/dt is 0. Therefore, the arc length parameter is simply s = t.

Now that we have the arc length parameter s, we can find the unit tangent vector T = dr/ds. Since dr/ds = dr/dt = (1, -1), the unit tangent vector T is (1, -1)/sqrt(2).

Next, we need to find ds/dt. Since s = t, ds/dt = 1.

Finally, we can calculate the curvature K using the formula K = |dT/ds| / |ds/dt|. In this case, dT/ds = 0, and |ds/dt| = 1. Therefore, the curvature at t = 1 is K = |dT/ds| / |ds/dt| = 0/1 = 0.

(b) The probability of Lukas Podolski scoring in either the World Cup quarter-final OR the semi-final match is 0.5 (or 50%).

What is Probability?

Probability is a branch of mathematics in which the chances of experiments occurring are calculated.

a) To find the probability that Lukas Podolski will score in both the World Cup quarter-final and semi-final matches, we multiply the probabilities of him scoring in each match since the events are independent.

Probability of scoring in the quarter-final match = 0.25 (or 25%)

Probability of scoring in the semi-final match = 0.25 (or 25%)

Probability of scoring in both matches = 0.25 * 0.25 = 0.0625

Therefore, the probability that Lukas Podolski will score in both the World Cup quarter-final and semi-final matches is 0.0625 (or 6.25%).

b) To find the probability of Lukas Podolski scoring in either the quarter-final OR the semi-final match, we can use the principle of addition. Since the events are mutually exclusive (he can't score in both matches simultaneously), we can simply add the probabilities of scoring in each match.

Probability of scoring in the quarter-final match = 0.25 (or 25%)

Probability of scoring in the semi-final match = 0.25 (or 25%)

a. The model equation for the number of cattle from 2000 through 2005 is C(t) = 0.69t - (0.132/3)t^3 + 0.044e^t + 95.472 - 0.044e^2

b.  The predicted number of cattle in 2007 (rounded to 1 decimal place) is 79.9 million cattle.

a. To find a model for the number of cattle from 2000 through 2005, we need to integrate the given rate of change equation.

dC = 0.69 - 0.132t^2 + 0.044e^t dt

Integrating both sides with respect to t:

∫dC = ∫(0.69 - 0.132t^2 + 0.044e^t) dt

C = 0.69t - (0.132/3)t^3 + 0.044e^t + C

Since the number of cattle in 2002 was 96.5 million, we can use this information to find the constant C. Plugging in t = 2 and C = 96.5 into the model equation:

96.5 = 0.692 - (0.132/3)(2^3) + 0.044e^2 + C

96.5 = 1.38 - 0.352 + 0.044e^2 + C

C = 96.5 - 1.38 + 0.352 - 0.044e^2

C = 95.472 - 0.044e^2

Now we have the model equation for the number of cattle from 2000 through 2005:

C(t) = 0.69t - (0.132/3)t^3 + 0.044e^t + 95.472 - 0.044e^2

b. To predict the number of cattle in 2007 (corresponding to t = 7), we can plug t = 7 into the model:

C(7) = 0.697 - (0.132/3)(7^3) + 0.044e^7 + 95.472 - 0.044e^2

C(7) = 4.83 - 20.412 + 0.044e^7 + 95.472 - 0.044e^2

C(7) = 79.89 + 0.044e^7 - 0.044e^2

Therefore, the predicted number of cattle in 2007 (rounded to 1 decimal place) is 79.9 million cattle.

The profit function, P(x), can be calculated by subtracting the cost function, C(x), from the revenue function, R(x), which is given by P(x) = R(x) - C(x). In this case, the profit function would be P(x) = (2x - 0.04x) - (182 + 1.3x).

The profit function represents the difference between the revenue generated from selling a certain quantity of goods or services and the cost incurred in producing and selling them. In this case, the revenue function, R(x), is given by 2x - 0.04x, where x represents the quantity of goods sold. This function calculates the total revenue obtained from selling x units, taking into account a fixed price per unit and a discount of 0.04 per unit.

The cost function, C(x), is given by 182 + 1.3x, where 182 represents the fixed costs and 1.3x represents the variable costs associated with producing x units. The variable cost per unit is 1.3, indicating that the cost increases linearly with the quantity produced.  

To calculate the profit function, P(x), we subtract the cost function from the revenue function, yielding P(x) = (2x - 0.04x) - (182 + 1.3x). Simplifying this expression, we have P(x) = 0.96x - 182.3, which represents the profit obtained from selling x units after considering the costs involved.

Using left and right endpoints, we can approximate the area of the region between the graph of the function f(x) = 2x - x² - 1 and the x-axis over the interval [0, x]. By dividing the interval into subintervals and evaluating the function at either the left or right endpoint of each subinterval, we can calculate the areas of the corresponding rectangles. Summing up these areas gives us two approximations of the total area.

To approximate the area using left endpoints, we divide the interval [0, x] into n subintervals of equal width. Each subinterval has a width of Δx = (x - 0)/n. We evaluate the function at the left endpoint of each subinterval and calculate the corresponding rectangle's area by multiplying the function value by the width Δx. The sum of these areas gives an approximation of the total area.

To approximate the area using right endpoints, we follow the same process but evaluate the function at the right endpoint of each subinterval. Again, we calculate the areas of the rectangles formed and sum them up to obtain an approximation of the total area.

By increasing the number of subintervals (n) and taking the limit as n approaches infinity, we can improve the accuracy of the approximations and approach the actual area of the region between the function and the x-axis over the interval [0, x].

The application of the Mean Value Theorem to the function f(x) = 3x² - 4x + 2 on the interval 2 < x < 4 guarantees the existence of at least one point c in the interval (2, 4) where the instantaneous rate of change (or slope) is equal to the average rate of change over the interval.

The Mean Value Theorem states that if a function f is continuous on the closed interval [a, b] and differentiable on the open interval (a, b), then there exists at least one point c in the interval (a, b) where the instantaneous rate of change (or derivative) of f at c is equal to the average rate of change of f over the interval [a, b].

In this case, the function f(x) = 3x² - 4x + 2 is a polynomial function, which is continuous and differentiable for all real numbers. Therefore, the conditions of the Mean Value Theorem are satisfied.

The interval given is 2 < x < 4. This interval lies within the domain of the function, and since f(x) is differentiable for all values of x, the Mean Value Theorem guarantees the existence of at least one point c in the interval (2, 4) where the instantaneous rate of change of f(x) is equal to the average rate of change over the interval [2, 4].

In other words, there exists a point c in the interval (2, 4) such that f'(c) = (f(4) - f(2))/(4 - 2), where f'(c) represents the derivative of f at c.

The derivative of the integral ∫[0, x] sin(13t) dt with respect to x is -sin(13x), in both the cases.

To find the derivative, we can evaluate the integral and then differentiate the result, as follows:

a. Evaluating the definite integral ∫[0, x] sin(13t) dt, we substitute the upper limit x and the lower limit 0 into the antiderivative of sin(13t), which is -cos(13t)/13.

Therefore, the result of the integral is (-cos(13x)/13) - (-cos(0)/13) = (-cos(13x) + 1)/13.

Next, we differentiate this result with respect to x. The derivative of (-cos(13x) + 1)/13 is given by (-13sin(13x))/13, which simplifies to -sin(13x).

Therefore, the derivative of the integral ∫[0, x] sin(13t) dt with respect to x is -sin(13x).

b. Alternatively, we can differentiate the integral directly using the Fundamental Theorem of Calculus. According to the theorem, if F(x) is the antiderivative of f(x), then the derivative of the integral ∫[a, x] f(t) dt with respect to x is F(x).

In this case, the antiderivative of sin(13t) is -cos(13t)/13. Therefore, the derivative of the integral ∫[0, x] sin(13t) dt with respect to x is -cos(13x)/13.

However, notice that -cos(13x)/13 can be further simplified to -sin(13x). Therefore, the derivative obtained by differentiating the integral directly is also -sin(13x). In both cases, we arrive at the same result, which is -sin(13x).

The point P on the line segment AB that is equidistant from A and B is approximately (-287/30, 571/210).

To find the point P on the line segment AB that is of the same distance from point A as it is from point B, we can use the concept of midpoint.

Point A(2, 1)

Point B(-11, -13)

To find the midpoint of the line segment AB, we can use the formula:

Midpoint = ((x₁ + x₂) / 2, (y₁ + y₂) / 2)

Let's substitute the coordinates of A and B into the formula to find the midpoint:

Midpoint = ((2 + (-11)) / 2, (1 + (-13)) / 2)

Midpoint = (-9/2, -12/2)

Midpoint = (-9/2, -6)

Now, we want to find the point P on the line segment AB that is of the same distance from point A as it is from point B.

Since P is equidistant from both A and B, it will lie on the perpendicular bisector of AB, passing through the midpoint.

To find the equation of the perpendicular bisector, we need the slope of AB.

The slope of AB can be calculated using the formula:

Slope = (y₂ - y₁) / (x₂ - x₁)

Slope of AB = (-13 - 1) / (-11 - 2)

Slope of AB = -14 / -13

Slope of AB = 14/13 (or approximately 1.08)

The slope of the perpendicular bisector will be the negative reciprocal of the slope of AB:

Slope of perpendicular bisector = -1 / (14/13)

Slope of perpendicular bisector = -13/14 (or approximately -0.93)

Now, we have the slope of the perpendicular bisector and a point it passes through (the midpoint).

We can use the point-slope form of a line to find the equation of the perpendicular bisector:

y - y₁ = m(x - x₁)

Using the midpoint (-9/2, -6) as (x₁, y₁) and the slope -13/14 as m, we can write the equation of the perpendicular bisector:

y - (-6) = (-13/14)(x - (-9/2))

y + 6 = (-13/14)(x + 9/2)

Simplifying the equation:

14(y + 6) = -13(x + 9/2)

14y + 84 = -13x - 117/2

14y = -13x - 117/2 - 84

14y = -13x - 117/2 - 168/2

14y = -13x - 285/2

Now, we have the equation of the perpendicular bisector.

To find the point P on the line segment AB that is equidistant from A and B, we need to find the intersection of the perpendicular bisector and the line segment AB.

Substituting the x-coordinate of P into the equation, we can solve for y:

-13x - 285/2 = 2x + 1

-15x = 1 + 285/2

-15x = 2/2 + 285/2

-15x = 287/2

x = (287/2)(-1/15)

x = -287/30

Substituting the y-coordinate of P into the equation, we can solve for x:

14y = -13(-287/30) - 285/2

14y = 287/30 + 285/2

14y = (287 + 855)/30

14y = 1142/30

y = (1142/30)(1/14)

y = 571/210

The solution to the initial value problem is y = 9/2 * e^(2x) + 7x + 49 - 9/2 * e^(-14).

To solve the initial value problem, we need to find the function y(x) that satisfies the given differential equation and initial condition.

The given differential equation is dy/dx = 9e^(2x) + 7.

To solve this, we can integrate both sides of the equation with respect to x:

∫ dy = ∫ (9e^(2x) + 7) dx

Integrating, we get:

y = 9/2 * e^(2x) + 7x + C

where C is the constant of integration.

To find the specific value of C, we use the initial condition y(-7) = 0. Substituting x = -7 and y = 0 into the equation, we can solve for C:

0 = 9/2 * e^(2*(-7)) + 7*(-7) + C

0 = 9/2 * e^(-14) - 49 + C

C = 49 - 9/2 * e^(-14)

Now we have the complete solution:

y = 9/2 * e^(2x) + 7x + 49 - 9/2 * e^(-14)

Therefore, the solution to the initial value problem is y = 9/2 * e^(2x) + 7x + 49 - 9/2 * e^(-14).

The area of the pentagon with vertices (0, 0), (3, 1), (1, 2), (0, 1), and (-2, 1) is 6 square units.

To find the area of a pentagon given its vertices, we can divide it into triangles and then calculate the area of each triangle separately.

Let's label the given vertices as A(0, 0), B(3, 1), C(1, 2), D(0, 1), and E(-2, 1). We can divide the pentagon into three triangles: ABD, BCD, and CDE.

To calculate the area of a triangle, we can use the shoelace formula. Let's apply it to each triangle:

Triangle ABD: Coordinates: A(0, 0), B(3, 1), D(0, 1)

Area(ABD) = |(0 * 1 + 3 * 1 + 0 * 0) - (0 * 3 + 1 * 0 + 1 * 0)| / 2

= |(0 + 3 + 0) - (0 + 0 + 0)| / 2

= |3 - 0| / 2

= 3 / 2

= 1.5 square units

Triangle BCD: Coordinates: B(3, 1), C(1, 2), D(0, 1)

Area(BCD) = |(3 * 2 + 1 * 0 + 0 * 1) - (1 * 1 + 2 * 0 + 3 * 0)| / 2

= |(6 + 0 + 0) - (1 + 0 + 0)| / 2

= |6 - 1| / 2

= 5 / 2

= 2.5 square units

Triangle CDE: Coordinates: C(1, 2), D(0, 1), E(-2, 1)

Area(CDE) = |(1 * 1 + 2 * 1 + (-2) * 0) - (2 * 0 + 1 * (-2) + 1 * 1)| / 2

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

= |3 - (-1)| / 2

= 4 / 2

= 2 square units

Now, we can sum up the areas of the three triangles to find the total area of the pentagon:

Total area = Area(ABD) + Area(BCD) + Area(CDE)

= 1.5 + 2.5 + 2

= 6 square units

Therefore, the area of the pentagon with vertices (0, 0), (3, 1), (1, 2), (0, 1), and (-2, 1) is 6 square units.
