The value of the given triple integral is 27/4.

We have to evaluate the given triple integral of the function xyz over the solid E. In order to do this, we will integrate over each of the three dimensions, starting with the innermost integral and working our way outwards.

The region E is defined by the inequalities 0 ≤ z ≤ 3, 0 ≤ y ≤ z, and 0 ≤ x ≤ y. These inequalities tell us that the solid is a triangular pyramid, with the base of the pyramid lying in the xy-plane and the apex of the pyramid located at the point (0,0,3).

We can integrate over the z-coordinate first since it is the simplest integral to evaluate. The limits of integration for z are from 0 to 3, as given in the problem statement. The integral becomes:

[tex]\[ \int_{0}^{3} \left( \int_{0}^{z} \left( \int_{0}^{y} x y z dx \right) dy \right) dz \][/tex]

Next, we can integrate over the y-coordinate. The limits of integration for y are from 0 to z. The integral becomes:

[tex]\[ \int_{0}^{3} \left( \int_{0}^{z} \left( \int_{0}^{y} x y z dx \right) dy \right) dz = \int_{0}^{3} \left( \int_{0}^{z} \frac{1}{2} y^2 z^2 dy \right) dz \][/tex]

Finally, we integrate over the x-coordinate. The limits of integration for x are from 0 to y. The integral becomes:

[tex]\[ \int_{0}^{3} \left( \int_{0}^{z} \frac{1}{2} y^2 z^2 dy \right) dz = \int_{0}^{3} \left( \int_{0}^{z} \frac{1}{2} y^2 z^2 dy \right) dz = \int_{0}^{3} \frac{1}{6} z^5 dz \][/tex]

Evaluating this integral gives us:

[tex]\[ \int_{0}^{3} \frac{1}{6} z^5 dz = \frac{1}{6} \left[ \frac{1}{6} z^6 \right]_{0}^{3} = \frac{1}{6} \cdot \frac{729}{6} = \frac{243}{36} = \frac{27}{4} \][/tex]

Therefore, the value of the given triple integral is 27/4.

A set of numbers that have exactly three factors are the numbers that are a result of multiplying two prime numbers together.

To explain further, let's first understand the concept of factors. A factor is a number that divides into another number without any remainder. For example, factors of 10 are 1, 2, 5, and 10. They are all the numbers that can be multiplied to produce 10. Now, if a number has exactly three factors, it means that it has two distinct prime factors. This is because a prime number only has two factors (1 and itself). Therefore, any number that is the product of two distinct prime numbers will have exactly three factors.

For example, consider the prime numbers 2 and 3. If we multiply them together, we get 6, which has exactly three factors: 1, 2, and 6. Another example is 5 and 7. If we multiply them together, we get 35, which has exactly three factors: 1, 5, and 35. Therefore, the set of numbers that have exactly three factors is the set of all products of two distinct prime numbers.

A nonzero linear function g(x) with a zero at x=4 can be written as [tex]g(x) = mx + b[/tex], where [tex]m = -b/4[/tex]  and b can be any nonzero constant.

To write a nonzero linear function g(x) that has a zero at [tex]x=4[/tex], you can use the slope-intercept form of a linear function, which is given by [tex]g(x) = mx + b.[/tex]

Since the function has a zero at [tex]x=4[/tex], this means that when [tex]x=4, g(x)[/tex] will equal zero.

To find the slope (m) of the function, we can use the formula

[tex]m = (y2 - y1) / (x2 - x1).[/tex]

Since we know that g(x) is zero when [tex]x=4[/tex], one point on the line is (4, 0).

Let's choose another point, (0, b), where b is a constant.

Using the formula for slope, we have [tex]m = (0 - b) / (4 - 0) = -b/4.[/tex]

Now, we can substitute the values of m and (4, 0) into the slope-intercept form to find b.

[tex]0 = (-b/4)(4) + b[/tex]

Simplifying the equation, we have[tex]0 = -b + b[/tex], which equals 0.

Since this equation is always true, it means that any value of b will satisfy the equation.

Therefore, a nonzero linear function [tex]g(x)[/tex] with a zero at [tex]x=4[/tex] can be written as [tex]g(x) = mx + b[/tex], where [tex]m = -b/4[/tex] and b can be any nonzero constant.

The value f(6π) is -sin(36π) + 60π + 4. To find f(6π), we need to integrate F''(x) twice and apply the initial conditions f'(0) = 4 and f(0) = 4.

Given F''(x) = -36sin(6x), we can integrate it once to find f'(x):

f'(x) = ∫(-36sin(6x))dx

      = -6cos(6x) + C1

Using the condition f'(0) = 4, we can solve for C1:

4 = -6cos(6(0)) + C1

4 = -6 + C1

C1 = 10

Now, we integrate f'(x) to find f(x):

f(x) = ∫(-6cos(6x) + 10)dx

     = -sin(6x) + 10x + C2

Using the condition f(0) = 4, we can solve for C2:

4 = -sin(6(0)) + 10(0) + C2

4 = 0 + 0 + C2

C2 = 4

So, the equation for f(x) is:

f(x) = -sin(6x) + 10x + 4

To find f(6π), we substitute x = 6π into the equation:

f(6π) = -sin(6(6π)) + 10(6π) + 4

The smaller number between the two is 3.5, obtained by solving the proportion (3-7) : (4-7) = 2 : 3.

Let's assume the two numbers are 3x and 4x (where x is a common multiplier).

According to the given condition, if we subtract 7 from each number, the remainder is in the ratio 2:3. So, we have the following equation:

(3x - 7)/(4x - 7) = 2/3

To solve this equation, we can cross-multiply:

3(4x - 7) = 2(3x - 7)

Simplifying the equation:

12x - 21 = 6x - 14

Subtracting 6x from both sides:

6x - 21 = -14

Adding 21 to both sides:

6x = 7

Dividing by 6:

x = 7/6

Now, we can substitute the value of x back into one of the original expressions to find the smaller number. Let's use 3x:

Smaller number = 3(7/6) = 21/6 = 3.5

Therefore, the smaller number between the two is 3.5.

If side a is perpendicular to the third side of the triangle, it implies that a = b * sin(A) since tan(A) = sin(A) / cos(A).

To show that if side a is perpendicular to the third side of the triangle, then a = b * sin(A), we can use the trigonometric relationship involving sine in a right triangle.

Let's consider a triangle ABC, where side a is perpendicular to the third side BC at point D. Angle A is opposite to side a. Side b is adjacent to angle A.

In triangle ABC, according to the definition of sine, we have:

sin(A) = opposite/hypotenuse

Since side a is perpendicular to side BC, it serves as the opposite side to angle A.

Therefore, sin(A) = a/hypotenuse.

Now, let's focus on side AC, which is the hypotenuse of the triangle. By using the definition of cosine, we have:

cos(A) = adjacent/hypotenuse

Since side b is adjacent to angle A, we can rewrite this equation as:

b = cos(A) * hypotenuse.

We can rearrange this equation to solve for hypotenuse:

hypotenuse = b / cos(A).

Now, substituting the value of hypotenuse into the equation sin(A) = a/hypotenuse, we get:

sin(A) = a / (b / cos(A)).

Multiplying both sides by (b / cos(A)), we have:

(b / cos(A)) * sin(A) = a.

Simplifying the left-hand side, we get:

b * (sin(A) / cos(A)) = a.

Using the identity tan(A) = sin(A) / cos(A), we can rewrite the equation as:

b * tan(A) = a.

Finally, dividing both sides of the equation by tan(A), we obtain:

a = b * tan(A).

So, if side a is perpendicular to the third side of the triangle, then a = b * tan(A).

Therefore, if side a is perpendicular to the third side of the triangle, it implies that a = b * sin(A) since tan(A) = sin(A) / cos(A).

The total work done on the particle by the force along the curve C when 0 ≤ t ≤ 1 is approximately 3.5698 units.

To find the total work done on the particle along the curve C, we need to evaluate the line integral of the force F(x, y) along the curve.

The curve C is given by r(t) = ⟨5 - 5t, 1 - t⟩ for 0 ≤ t ≤ 1, and the force F(x, y) = ⟨arctan(y), 1 + y, 2x⟩.

By calculating and simplifying the line integral, we can determine the total work done on the particle.

The line integral of a vector field F along a curve C is given by ∫ F · dr, where dr is the differential displacement along the curve C.

In this case, we have the curve C parameterized by r(t) = ⟨5 - 5t, 1 - t⟩ for 0 ≤ t ≤ 1, and the force field F(x, y) = ⟨arctan(y), 1 + y, 2x⟩.

To find the work done, we first need to express the differential displacement dr in terms of t.

Since r(t) is given as ⟨5 - 5t, 1 - t⟩, we can find the derivative of r(t) with respect to t: dr/dt = ⟨-5, -1⟩. This gives us the differential displacement along the curve.

Next, we evaluate F(r(t)) · dr along the curve C by substituting the components of r(t) and dr into the expression for F(x, y).

We have F(r(t)) = ⟨arctan(1 - t), 1 + (1 - t), 2(5 - 5t)⟩ = ⟨arctan(1 - t), 2 - t, 10 - 10t⟩.

Taking the dot product of F(r(t)) and dr, we have F(r(t)) · dr = ⟨arctan(1 - t), 2 - t, 10 - 10t⟩ · ⟨-5, -1⟩ = -5(arctan(1 - t)) + (2 - t) + 10(1 - t).

Now we integrate F(r(t)) · dr over the interval 0 ≤ t ≤ 1 to find the total work done:

∫[0,1] (-5(arctan(1 - t)) + (2 - t) + 10(1 - t)) dt.

To evaluate the integral ∫[0,1] (-5(arctan(1 - t)) + (2 - t) + 10(1 - t)) dt, we can simplify the integrand and then compute the integral term by term.

Expanding the terms inside the integral, we have:

∫[0,1] (-5arctan(1 - t) + 2 - t + 10 - 10t) dt.

Simplifying further, we get:

∫[0,1] (-5arctan(1 - t) - t - 8t + 12) dt.

Now, we can integrate term by term.

The integral of -5arctan(1 - t) with respect to t can be challenging to find analytically, so we may need to use numerical methods or approximation techniques to evaluate that part.

However, we can integrate the remaining terms straightforwardly.

The integral becomes:

-5∫[0,1] arctan(1 - t) dt - ∫[0,1] t dt - 8∫[0,1] t dt + 12∫[0,1] dt.

The integrals of t and dt can be easily calculated:

-5∫[0,1] arctan(1 - t) dt = -5[∫[0,1] arctan(u) du] (where u = 1 - t)

∫[0,1] t dt = -[t^2/2] evaluated from 0 to 1

8∫[0,1] t dt = -8[t^2/2] evaluated from 0 to 1

12∫[0,1] dt = 12[t] evaluated from 0 to 1

Simplifying and evaluating the integrals at the limits, we get:

-5[∫[0,1] arctan(u) du] = -5[arctan(1) - arctan(0)]

[t^2/2] evaluated from 0 to 1 = -(1^2/2 - 0^2/2)

8[t^2/2] evaluated from 0 to 1 = -8(1^2/2 - 0^2/2)

12[t] evaluated from 0 to 1 = 12(1 - 0)

Substituting the values into the respective expressions, we have:

-5[arctan(1) - arctan(0)] - (1^2/2 - 0^2/2) - 8(1^2/2 - 0^2/2) + 12(1 - 0)

Simplifying further:

-5[π/4 - 0] - (1/2 - 0/2) - 8(1/2 - 0/2) + 12(1 - 0)

= -5(π/4) - (1/2) - 8(1/2) + 12

= -5π/4 - 1/2 - 4 + 12

= -5π/4 - 9/2 + 12

Now, we can calculate the numerical value of the expression:

≈ -3.9302 - 4.5 + 12

≈ 3.5698

Stokes' Theorem is not satisfied for the given case so it is not true for the given vector field F and surface S.

To verify Stokes' Theorem for the given vector field F and surface S,

calculate the surface integral of the curl of F over S and compare it with the line integral of F around the boundary curve of S.

Let's start by calculating the curl of F,

F(x, y, z) = yi + zj + xk,

The curl of F is given by the determinant,

curl(F) = ∇ x F

          = (d/dx, d/dy, d/dz) x (yi + zj + xk)

Expanding the determinant, we have,

curl(F) = (d/dy(x), d/dz(y), d/dx(z))

           = (0, 0, 0)

The curl of F is zero, which means the surface integral over any closed surface will also be zero.

Now let's consider the hemisphere surface S, defined by x²+ y² + z² = 1, where y ≥ 0, oriented in the direction of the positive y-axis.

The boundary curve of S is a circle in the xz-plane with radius 1, centered at the origin.

According to Stokes' Theorem, the surface integral of the curl of F over S is equal to the line integral of F around the boundary curve of S.

Since the curl of F is zero, the surface integral of the curl of F over S is also zero.

Now, let's calculate the line integral of F around the boundary curve of S,

The boundary curve lies in the xz-plane and is parameterized as follows,

r(t) = (cos(t), 0, sin(t)), 0 ≤ t ≤ 2π

To calculate the line integral,

evaluate the dot product of F and the tangent vector of the curve r(t), and integrate it with respect to t,

∫ F · dr

= ∫ (yi + zj + xk) · (dx/dt)i + (dy/dt)j + (dz/dt)k

= ∫ (0 + sin(t) + cos(t)) (-sin(t)) dt

= ∫ (-sin(t)sin(t) - sin(t)cos(t)) dt

= ∫ (-sin²(t) - sin(t)cos(t)) dt

= -∫ (sin²(t) + sin(t)cos(t)) dt

Using trigonometric identities, we can simplify the integral,

-∫ (sin²(t) + sin(t)cos(t)) dt

= -∫ (1/2 - (1/2)cos(2t) + (1/2)sin(2t)) dt

= -[t/2 - (1/4)sin(2t) - (1/4)cos(2t)] + C

Evaluating the integral from 0 to 2π,

-∫ F · dr

= [-2π/2 - (1/4)sin(4π) - (1/4)cos(4π)] - [0/2 - (1/4)sin(0) - (1/4)cos(0)]

= -π

The line integral of F around the boundary curve of S is -π.

Since the surface integral of the curl of F over S is zero

and the line integral of F around the boundary curve of S is -π,

Stokes' Theorem is not satisfied for this particular case.

Therefore, Stokes' Theorem is not true for the given vector field F and surface S.

Multiplying g(x) by -1 will reflect it over the x-axis. Thus, the new equation becomes f(x) = -(-g(x)) + 8, which simplifies to f(x) = g(x) + 8.

Next, we need to account for the horizontal shift. Shifting g(x) right by 12 units means replacing x with (x - 12) in the equation. Therefore, the final equation for f(x) is f(x) = g(x - 12) + 8. This equation represents the combined transformations of reflecting g(x) over the y-axis, shifting it up eight units, dilating it by -1, and shifting it horizontally right 12 units.

a. CCA's current liabilities are approximately $21,000. b. CCA's inventory is approximately $10,500.

To find the current liabilities and inventory of Credit Card of America (CCA), we can use the current ratio and quick ratio along with the given information.

(a) Current liabilities:

The current ratio is calculated as the ratio of current assets to current liabilities. In this case, the current ratio is 3.5, which means that for every dollar of current liabilities, CCA has $3.5 of current assets.

Let's assume the current liabilities as 'x'. We can set up the following equation based on the given information:

3.5 = $73,500 / x

Solving for 'x', we find:

x = $73,500 / 3.5 ≈ $21,000

Therefore, CCA's current liabilities are approximately $21,000.

(b) Inventory:

The quick ratio is calculated as the ratio of current assets minus inventory to current liabilities. In this case, the quick ratio is 3.0, which means that for every dollar of current liabilities, CCA has $3.0 of current assets excluding inventory.

Using the given information, we can set up the following equation:

3.0 = ($73,500 - Inventory) / $21,000

Solving for 'Inventory', we find:

Inventory = $73,500 - (3.0 * $21,000)

Inventory ≈ $73,500 - $63,000

Inventory ≈ $10,500

Therefore, CCA's inventory is approximately $10,500.

The quadratic function equation: y = ax^2 + bx + c, with c = 2, to obtain the quadratic model.

To determine whether a quadratic model exists for the given set of values (-1, 1/2), (0, 2), and (2, 2), we can check if the points lie on a straight line. If they do, a linear model would be appropriate..

However, if the points do not lie on a straight line, a quadratic model may be suitable.

To check this, we can plot the points on a graph or calculate the slope between consecutive points. If the slope is not constant, then a quadratic model may be appropriate.

Let's calculate the slopes between the given points

- The slope between (-1, 1/2) and (0, 2) is (2 - 1/2) / (0 - (-1)) = 3/2.

- The slope between (0, 2) and (2, 2) is (2 - 2) / (2 - 0) = 0.

As the slopes are not constant, a quadratic model may be appropriate.

Now, let's write the quadratic model. We can use the general form of a quadratic function: y = ax^2 + bx + c.

To find the coefficients a, b, and c, we substitute the given points into the quadratic function:

For (-1, 1/2):
1/2 = a(-1)^2 + b(-1) + c

For (0, 2):
2 = a(0)^2 + b(0) + c

For (2, 2):
2 = a(2)^2 + b(2) + c

Simplifying these equations, we get:
1/2 = a - b + c    (equation 1)
2 = c               (equation 2)
2 = 4a + 2b + c     (equation 3)

Using equation 2, we can substitute c = 2 into equations 1 and 3:

1/2 = a - b + 2    (equation 1)
2 = 4a + 2b + 2     (equation 3)

Now we have a system of two equations with two variables (a and b). By solving these equations simultaneously, we can find the values of a and b.

After finding the values of a and b, we can substitute them back into the quadratic function equation: y = ax^2 + bx + c, with c = 2, to obtain the quadratic model.

The set of values (-1, 1/2), (0, 2), (2, 2), we can determine whether a quadratic model exists by checking if the points lie on a straight line. To do this, we can first plot the points on a coordinate plane. After plotting the points, we can see that they do not lie on a straight line. The quadratic model for the given set of values is: y = (-3/8)x^2 - (9/8)x + 2.

To find the quadratic model, we can use the standard form of a quadratic equation: y = ax^2 + bx + c.

Substituting the given points into the equation, we get three equations:

1/2 = a(-1)^2 + b(-1) + c
2 = a(0)^2 + b(0) + c
2 = a(2)^2 + b(2) + c

Simplifying these equations, we get:

1/2 = a - b + c
2 = c
2 = 4a + 2b + c

Since we have already determined that c = 2, we can substitute this value into the other equations:

1/2 = a - b + 2
2 = 4a + 2b + 2

Simplifying further, we get:

1/2 = a - b + 2
0 = 4a + 2b

Rearranging the equations, we have:

a - b = -3/2
4a + 2b = 0

Now, we can solve this system of equations to find the values of a and b. After solving, we find that a = -3/8 and b = -9/8.

Therefore, the quadratic model for the given set of values is:

y = (-3/8)x^2 - (9/8)x + 2.

This model represents the relationship between x and y based on the given set of values.

The closest distance a person travels in one revolution of the Ferris wheel with a diameter of 250 ft is approximately 785 ft.

To find the distance a person travels in one revolution of a Ferris wheel with a diameter of 250 ft, we need to calculate the circumference of the wheel.

The circumference of a circle is given by the formula C = πd,

where C is the circumference and d is the diameter.

In this case, the diameter is given as 250 ft. Plugging this value into the formula, we have:

C = πd = π(250 ft) ≈ 3.14 × 250 ft ≈ 785 ft

Therefore, the closest answer choice to the distance a person travels in one revolution is 785 ft.

This means that for every complete revolution of the Ferris wheel, a person would travel a distance approximately equal to the calculated circumference of 785 ft.

The other answer choices (393 ft., 1570 ft., and 49063 ft.) are further away from the calculated circumference and do not accurately represent the distance traveled in one revolution.

The missing terms between -320 and 5 in the geometric sequence are -40 and -5.

Explanation:

To find the missing terms in a geometric sequence, we need to determine the common ratio (r) first. The common ratio can be found by dividing any term by its preceding term.

Let's consider te given terms: -320 and 5. To find the common ratio, we divide 5 by -320:r = 5 / (-320) = -1/64

Now that we know the common ratio (r = -1/64), we can find the missing terms.

To find the first missing term, we multiply the preceding term (-320) by the common ratio:-320 * (-1/64) = 5

So, the first missing term is 5.

To find the second missing term, we multiply the preceding term (5) by the common ratio:5 * (-1/64) = -5/64

Hence, the second missing term is -5/64 or -0.078125.

Using the trapezoidal rule, the integral evaluates to approximately 52.2. The Simpson's rule estimate for n=4 yields an approximate value of 53.22.

To evaluate the integral ∫(3s^2)/5 ds from 2 to 9 using the trapezoidal rule, we divide the interval [2, 9] into 4 equal subintervals. The formula for the trapezoidal rule estimate is:

Trapezoidal Rule Estimate = [h/2] * [f(x0) + 2f(x1) + 2f(x2) + ... + 2f(xn-1) + f(xn)],

where h is the width of each subinterval and f(xi) represents the function evaluated at each x-value.

For n=4, we have h = (9 - 2)/4 = 1.75. Evaluating the function at each x-value and applying the formula, we obtain the trapezoidal rule estimate.

To determine an upper bound for the error of the trapezoidal rule estimate, we use the formula:

|ET| ≤ [(b - a)^3 / (12n^2)] * |f''(c)|,

where |f''(c)| is the maximum value of the second derivative of the function within the interval [2, 9]. Calculating the upper bound, we obtain |ET|.

The percentage of the error relative to the true value is given by (|ET| / True Value) * 100%.

Next, we use Simpson's rule to estimate the integral for n=4. The formula for Simpson's rule estimate is:

Simpson's Rule Estimate = [h/3] * [f(x0) + 4f(x1) + 2f(x2) + 4f(x3) + 2f(x4) + ... + 2f(xn-2) + 4f(xn-1) + f(xn)].

Substituting the values and evaluating the function at each x-value, we obtain the Simpson's rule estimate.

To determine an upper bound for the error of the Simpson's rule estimate, we use the formula:

|ES| ≤ [(b - a)^5 / (180n^4)] * |f''''(c)|,

where |f''''(c)| is the maximum value of the fourth derivative of the function within the interval [2, 9]. Calculating the upper bound, we obtain |ES|.

The level at which the soda is dropping after 5 seconds is approximately 12.07 cm.

To find the level at which the soda is dropping, we can use the concept of volume and relate it to the rate of consumption.

The volume of liquid consumed per second can be calculated as the rate of consumption multiplied by the time:

V = r * t

where V is the volume, r is the rate of consumption, and t is the time.

In this case, the rate of consumption is given as 4 cm^3 per second. Let's assume the height at which the soda is dropping is h.

The volume of the cup can be calculated using the formula for the volume of a cylinder:

V_cup = π * r^2 * h

Since the cup is being consumed at a constant rate, the change in the volume of the cup with respect to time is equal to the rate of consumption:

dV_cup/dt = r

Taking the derivative of the volume equation with respect to time, we have:

dV_cup/dt = π * r^2 * dh/dt

Setting this equal to the rate of consumption:

π * r^2 * dh/dt = r

Simplifying the equation:

dh/dt = 1 / (π * r^2)

Substituting the given value of the cup's radius, which is 6 cm, into the equation:

dh/dt = 1 / (π * (6^2))

      = 1 / (π * 36)

      ≈ 0.0088 cm/s

This means that the soda level is dropping at a rate of approximately 0.0088 cm/s.

To find the level at which the soda is dropping, we can integrate the rate of change of the level with respect to time:

∫dh = ∫(1 / (π * 36)) dt

Integrating both sides:

h = (1 / (π * 36)) * t + C

Since we want to find the level at which the soda is dropping, we need to find the value of C. Given that the initial level is the full height of the cup, which is 2 times the radius, we have h(0) = 2 * 6 = 12 cm.

Plugging in the values, we can solve for C:

12 = (1 / (π * 36)) * 0 + C

C = 12

Therefore, the equation for the level of the soda as a function of time is:

h = (1 / (π * 36)) * t + 12

To find the level at which the soda is dropping, we can substitute the given time into the equation. For example, if we want to find the level after 5 seconds:

h = (1 / (π * 36)) * 5 + 12

h ≈ 12.07 cm

Therefore, the level at which the soda is dropping after 5 seconds is approximately 12.07 cm.

g(x) = f(1/2 * x) = (1/2 * x) - 3

We can use technology to graph both f(x) and g(x) and verify that g(x) is a horizontally stretched version of f(x).

In the input bar, type "y = x - 3" and press enter to graph f(x).

In the input bar, type "y = (1/2 * x) - 3" and press enter to graph g(x).

The two graphs should appear on the same coordinate plane, with g(x) appearing horizontally compressed by a factor of 2 compared to f(x).

Alternatively, we can also check our answer algebraically by plugging in values for x and verifying that the corresponding y-values for g(x) are horizontally compressed by a factor of 2 compared to f(x). For example:

When x = 0, f(x) = -3 and g(x) = -3.

When x = 2, f(x) = -1 and g(x) = -2.

When x = 4, f(x) = 1 and g(x) = -1.

When x = 6, f(x) = 3 and g(x) = 0.

We can see that the y-values for g(x) are horizontally compressed by a factor of 2 compared to the y-values for f(x), which confirms that g(x) is a horizontally stretched version of f(x).

From the coordinates of the intersection point (3, 0), we would shade the region below the line 2x + 3y = 6 and above the line x - y = 3.

To find the coordinates of the intersection point and determine the shading region, we need to solve the system of inequalities.

The first inequality is x - y ≤ 3. We can rewrite this as y ≥ x - 3.

The second inequality is 2x + 3y < 6. We can rewrite this as y < (6 - 2x) / 3.

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

x - 3 = (6 - 2x) / 3

Simplifying, we have:

3(x - 3) = 6 - 2x

3x - 9 = 6 - 2x

5x = 15

x = 3

Substituting x = 3 into either equation, we find:

y = 3 - 3 = 0

Therefore, the intersection point is (3, 0).

To determine the shading region, we can choose a test point not on the boundary lines. Let's use the point (0, 0).

For the inequality y ≥ x - 3:

0 ≥ 0 - 3

0 ≥ -3

Since the inequality is true, we shade the region above the line x - y = 3.

For the inequality y < (6 - 2x) / 3:

0 < (6 - 2(0)) / 3

0 < 6/3

0 < 2

Since the inequality is true, we shade the region below the line 2x + 3y = 6.
