a water jug is in the shape of a prism the area of the base is 100 square inches and the height is 20 inches how many gallons of water can it hold (1 gallon equals 231 inches cubed)

The slope intercept form of the given equation in the graph is y=-25x+100.

From the given graph, we have (2, 50) and (0, 100).

The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.

The standard form of the slope intercept form is y=mx+c.

Here, slope (m) = (100-50)/(0-2)

= -25

Now, substitute m=-25 and (x, y)=(2, 50) in y=mx+c, we get

50=-25×2+c

c=100

So, the equation is y=-25x+100

Therefore, the slope intercept form of the given equation in the graph is y=-25x+100.

15 units is the area can be deduced by the ellipse.

To graph the circle and ellipse, we start with the equations:

Circle: x^2 + y^2 = 25

Ellipse: x^2/225 + y^2/16 = 1

Now, let's draw the vertical line x = -2 and find the points of intersection with the circle and ellipse.

For the circle:

x = -2

(-2)^2 + y^2 = 25

4 + y^2 = 25

y^2 = 21

y = ±√21

Therefore, the points of intersection with the circle are A(-2, √21) and B(-2, -√21).

For the ellipse:

x = -2

(-2)^2/225 + y^2/16 = 1

4/225 + y^2/16 = 1

y^2/16 = 1 - 4/225

y^2/16 = 221/225

y^2 = (221/225) * 16

y = ±√(221/225) * 4

Thus, the points of intersection with the ellipse are C(-2, √(221/225) * 4) and D(-2, -√(221/225) * 4).

Now, let's calculate the ratio of AB to CD.

Distance AB:

AB = √[(-2 - (-2))^2 + (√21 - (-√21))^2]

= √[0 + (2√21)^2]

= √[4 * 21]

= √84

= 2√21

Distance CD:

CD = √[(-2 - (-2))^2 + (√(221/225) * 4 - (-√(221/225) * 4))^2]

= √[0 + (8√(221/225))^2]

= √[(64/225) * 221]

= √(14.784)

= √(14784/1000)

= (1/10)√(14784)

= (1/10) * 384

= 38.4/10

= 3.84

Therefore, the ratio AB:CD is 2√21:3.84, which simplifies to 5:3.

Let's choose a different vertical line and repeat the calculation.

Let's take the line x = 3.

For the circle:

x = 3

3^2 + y^2 = 25

9 + y^2 = 25

y^2 = 16

y = ±4

The points of intersection with the circle are A(3, 4) and B(3, -4).

For the ellipse:

x = 3

3^2/225 + y^2/16 = 1

9/225 + y^2/16 = 1

y^2/16 = 1 - 9/225

y^2/16 = 216/225

y^2 = (216/225) * 16

y = ±√(216/225) * 4

The points of intersection with the ellipse are C(3, √(216/225) * 4) and D(3, -√(216/225) * 4).

Now, let's calculate the ratio of AB to CD.

Distance AB:

AB = √[(3 - 3)^2 + (4 - (-4))^2]

= √[0 + 64]

= √64

= 8

Distance CD:

CD = √[(3 - 3)^2 + (√(216/225) * 4 - (-√(216/225) * 4))^2]

= √[0 + (8√(216/225))^2]

= √[(64/225) * 216]

= √(15.36)

= √(1536/100)

= (1/10)√(1536)

= (1/10) * 39.2

= 3.92/10

= 0.392

Therefore, the ratio AB:CD is 8:0.392, which simplifies to 20:0.98, or approximately 20:1.

Now, let's find expressions for the chord lengths using the line x = k, where |k| < 5.

For the circle:

x = k

k^2 + y^2 = 25

y^2 = 25 - k^2

y = ±√(25 - k^2)

For the ellipse:

x = k

k^2/225 + y^2/16 = 1

y^2/16 = 1 - k^2/225

y^2 = 16 - (16/225) * k^2

y = ±√(16 - (16/225) * k^2)

Now, let's calculate the ratio of the chord lengths for the general case.

Distance AB:

AB = √[(k - k)^2 + (√(25 - k^2) - (-√(25 - k^2)))^2]

= √[0 + 4(25 - k^2)]

= 2√(25 - k^2)

Distance CD:

CD = √[(k - k)^2 + (√(16 - (16/225) * k^2) - (-√(16 - (16/225) * k^2)))^2]

= √[0 + 4(16 - (16/225) * k^2)]

= 2√(16 - (16/225) * k^2)

Therefore, the ratio AB:CD is 2√(25 - k^2):2√(16 - (16/225) * k^2), which simplifies to √(25 - k^2):√(16 - (16/225) * k^2), and further simplifies to 5:3.

The ratio 5:3 appears most conspicuously in the calculation of the chord lengths, where it remains constant regardless of the position of the vertical line x = k.

Since the area enclosed by the circle is known to be 25, and the ratio of the chord lengths for the circle and ellipse is 5:3, we can deduce that the area enclosed by the ellipse is (3/5) * 25 = 15 units.

The diver collected water samples at every 3 meters, starting from 5 meters below the water surface, up to a final depth of 35 meters.

We can find the number of samples collected by dividing the total depth range by the distance between each sample and then adding 1 to include the first sample.

The total depth range is:

35 m - 5 m = 30 m

The distance between each sample is 3 m, so the number of samples is:

(30 m) / (3 m/sample) + 1 = 10 + 1 = 11

Therefore, the diver collected a total of 11 water samples.

If the expectation is E(x)=0.5 then the value of a =1 and b=0

To find the values of a and b, we need to solve two equations. First, we know that the expectation of X (E(X)) is equal to the integral of x times the density function f(x) over the entire range of X. Using this, we can set up the equation:

E(X) = ∫[0,1] (x * (a + bx^2)) dx

Since E(X) is given as 0.5, we have:

0.5 = ∫[0,1] (x * (a + bx^2)) dx

The second equation comes from the fact that the density function must integrate to 1 over its entire range:

∫[0,1] (a + bx^2) dx = 1

Solving these two equations will give us the values of a and b.

To solve the equations, we need to integrate the expressions involved and set them equal to the given values.

First, let's solve the equation for E(X):

0.5 = ∫[0,1] (x * (a + bx^2)) dx

0.5 = a∫[0,1] (x) dx + b∫[0,1] (x^3) dx

Integrating the expressions, we have:

0.5 = a * [[tex]x^2[/tex]/2] + b * [[tex]x^4[/tex]/4] evaluated from 0 to 1

0.5 = a * ([tex]1^2[/tex]/2) + b * ([tex]1^4[/tex]/4) - a * ([tex]0^2[/tex]/2) - b * ([tex]0^4[/tex]/4)

0.5 = a/2 + b/4

Next, let's solve the equation for the integral of the density function:

∫[0,1] (a + bx^2) dx = 1

Integrating the expression, we have:

a∫[0,1] (1) dx + b∫[0,1] (x^2) dx = 1

a * [x] evaluated from 0 to 1 + b * [[tex]x^3[/tex]/3] evaluated from 0 to 1 = 1

a * (1 - 0) + b * ([tex]1^3[/tex]

/3 - 0) = 1

a + b/3 = 1

Now we have a system of equations:

0.5 = a/2 + b/4

a + b/3 = 1

Solving this system of equations will give us the values of a and b.

To solve the system of equations:

0.5 = a/2 + b/4   ...(1)

a + b/3 = 1       ...(2)

We can multiply equation (1) by 4 and equation (2) by 6 to eliminate the fractions:

2 = 2a + b

6a + 2b = 6

Now we have a system of two linear equations:

2a + b = 2   ...(3)

6a + 2b = 6   ...(4)

Multiplying equation (3) by 2, we get:

4a + 2b = 4   ...(5)

Subtracting equation (5) from equation (4), we eliminate b:

6a + 2b - (4a + 2b) = 6 - 4

2a = 2

a = 1

Substituting the value of a into equation (3), we can solve for b:

2(1) + b = 2

2 + b = 2

b = 0

Therefore, the values of a and b that satisfy the equations are:

a = 1

b = 0

The area enclosed by the given ellipse is -abπ, where a and b are the lengths of the semi-major and semi-minor axes of the ellipse, respectively.

To find the area enclosed by the given ellipse with parametric equations x = a cos(t) and y = b sin(t), where 0 ≤ t ≤ 2π, we can use the formula for the area of a parametric curve.

The formula for the area A of a parametric curve defined by x = f(t) and y = g(t) over the interval [a, b] is:

A = ∫[a,b] y(t) * x'(t) dt

In this case, we have x = a cos(t) and y = b sin(t).

Let's calculate the area enclosed by the ellipse:

A = ∫[0, 2π] (b sin(t)) * (-a sin(t)) dt

A = -ab ∫[0, 2π] sin^2(t) dt

Using the trigonometric identity sin^2(t) = (1/2)(1 - cos(2t)), we can rewrite the integral as:

A = -ab ∫[0, 2π] (1/2)(1 - cos(2t)) dt

Expanding the integral:

A = -ab * (1/2) ∫[0, 2π] dt + ab * (1/2) ∫[0, 2π] cos(2t) dt

The first integral is simply the length of the interval [0, 2π], which is 2π:

A = -ab * (1/2) * 2π + ab * (1/2) ∫[0, 2π] cos(2t) dt

Simplifying:

A = -abπ + ab * (1/2) ∫[0, 2π] cos(2t) dt

The integral of cos(2t) with respect to t is sin(2t)/2, so:

A = -abπ + ab * (1/2) * [sin(2t)/2] evaluated from 0 to 2π

A = -abπ + ab * (1/2) * [sin(4π)/2 - sin(0)/2]

Since sin(4π) = sin(0) = 0, the second term in the brackets becomes zero:

A = -abπ + 0

A = -abπ

Therefore, the area enclosed by the given ellipse is -abπ, where a and b are the lengths of the semi-major and semi-minor axes of the ellipse, respectively.

The transition matrix from basis b = {(1,3), (-5,-5)} to basis b' = {(-30,0), (-10,10)} is T = [-5 -5], [5 -1].

To find the transition matrix from basis b = {(1,3), (-5,-5)} to basis b' = {(-30,0), (-10,10)}, we need to express the vectors in basis b' as linear combinations of the vectors in basis b. The transition matrix will have the vectors in b' expressed as columns.

Let's denote the vectors in basis b as v₁ = (1,3) and v₂ = (-5,-5), and the vectors in basis b' as w₁ = (-30,0) and w₂ = (-10,10).

We need to find coefficients such that w₁ = c₁v₁ + c₂v₂ and w₂ = d₁v₁ + d₂v₂.

For w₁ = (-30,0), we have:

(-30,0) = c₁(1,3) + c₂(-5,-5)

Expanding the equation, we get two equations:

-30 = c₁ - 5c₂ (equation 1)

0 = 3c₁ - 5c₂ (equation 2)

Solving these equations simultaneously, we find:

c₁ = -5

c₂ = 5

Therefore, we can write (-30,0) = -5(1,3) + 5(-5,-5).

For w₂ = (-10,10), we have:

(-10,10) = d₁(1,3) + d₂(-5,-5)

Expanding the equation, we get two equations:

-10 = d₁ - 5d₂ (equation 3)

10 = 3d₁ - 5d₂ (equation 4)

Solving these equations simultaneously, we find:

d₁ = -5

d₂ = -1

Therefore, we can write (-10,10) = -5(1,3) - (1)(-5,-5).

Now, we can construct the transition matrix by arranging the coefficients as columns. The transition matrix T is given by:

T = [c₁ d₁]

[c₂ d₂]

Substituting the values of c₁, c₂, d₁, and d₂, we have:

T = [-5 -5]

[5 -1]

Therefore, the transition matrix from basis b = {(1,3), (-5,-5)} to basis b' = {(-30,0), (-10,10)} is:

T = [-5 -5]

[5 -1]

The transition matrix T allows us to convert coordinates from basis b to basis b' and vice versa.

The graph of the quadratic surface x^2 + 100y^2 - 36z^2 = 100 is an elliptic paraboloid centered at the origin in three-dimensional space.

To sketch this surface, we can first consider cross-sections of the surface parallel to the xy-plane and the xz-plane. If we set z=0, then we have:

x^2 + 100y^2 = 100

This is an ellipse centered at the origin with semi-axes of length 10 along the y-axis and length 1 along the x-axis.

Similarly, if we set y=0, then we have:

x^2 - 36z^2 = 100

This is a hyperbola centered at the origin with its branches opening along the x-axis.

Finally, we can consider cross-sections of the surface parallel to the yz-plane. If we set x=0, then we have:

100y^2 - 36z^2 = 100

Dividing both sides by 100, we get:

y^2 - (9/25)z^2 = 1

This is also a hyperbola, but with its branches opening along the y-axis.

Combining all of these cross-sections, we get a three-dimensional shape that looks like a bowl with a rim extending infinitely far away from the origin in all directions. The edge of the rim lies along the plane where z=0. The bowl is elongated along the y-axis, and flattened along the x-axis, due to the fact that the coefficient of y^2 is greater than the coefficient of x^2. However, the bowl is not as deep along the z-axis as it would be in the case of a simple elliptic paraboloid, due to the negative sign on the z^2 term. This causes the branches of the hyperbolas in the yz-plane to curve inward towards the origin as they move away from the z=0 plane.

These (Non-negativity, Monotonicity, Right-continuity) three properties collectively define a function as a cumulative distribution function.

To establish that a function f(x) is a cumulative distribution function (CDF), we need to verify three essential properties: non-negativity, monotonicity, and right-continuity.

Non-negativity:

The first property requires that the CDF is non-negative for all values of x. In other words, f(x) ≥ 0 for all x. This condition ensures that the cumulative probabilities assigned by the CDF are non-negative values.

Monotonicity:

The second property states that the CDF must be non-decreasing. If x1 < x2, then it follows that f(x1) ≤ f(x2). This means that as we move along the x-axis from left to right, the cumulative probability assigned by the CDF cannot decrease. It can either remain the same or increase.

Right-continuity:

The third property demands that the CDF is right-continuous. This means that the limit of f(x) as x approaches a from the right exists and is equal to f(a). In simpler terms, if we approach a specific value of x from the right side, the cumulative probability assigned by the CDF should remain unchanged at that value.

These three properties collectively define a function as a cumulative distribution function. To determine if a given function satisfies these criteria, we would need the specific function f(x) in question. Once provided, we can assess whether the function adheres to the non-negativity, monotonicity, and right-continuity properties, thereby establishing it as a cumulative distribution function.

The exact value of sin(u-v) is -77/85. This can be answered by the concept of Trigonometry.

Given the information, we can find the exact value of sin(u-v).

We know that sin(u) = -3/5 and cos(v) = 15/17. Since 3/2 < u < 2, u is in the fourth quadrant where sin is negative, and 0 < v < π/2, v is in the first quadrant where cos is positive.

We can use the trigonometric identity for sin(u-v): sin(u-v) = sin(u)cos(v) - cos(u)sin(v).

First, we need to find cos(u) and sin(v). We can use the Pythagorean identities: sin²(u) + cos²(u) = 1 and sin²(v) + cos²(v) = 1.

For u:
sin²(u) = (-3/5)² = 9/25
cos²(u) = 1 - sin²(u) = 1 - 9/25 = 16/25
cos(u) = √(16/25) = 4/5 (cos is positive in the fourth quadrant)

For v:
cos²(v) = (15/17)² = 225/289
sin²(v) = 1 - cos²(v) = 1 - 225/289 = 64/289
sin(v) = √(64/289) = 8/17 (sin is positive in the first quadrant)

Now we can use the identity sin(u-v) = sin(u)cos(v) - cos(u)sin(v):
sin(u-v) = (-3/5)(15/17) - (4/5)(8/17) = -45/85 - 32/85 = -77/85

So, the exact value of sin(u-v) is -77/85.

The sum using sigma notation starting from i = 1, is as follows:∑i=1^10 ( -5 + (i-1)7 ).

Sigma notation is an efficient method for expressing sums of large quantities. It is denoted by the symbol Sigma (Σ).

The following is the formula for the sum of 'n' terms that start with 'a' and have a common difference of 'd':

Sum of n terms = (n/2)[2a + (n - 1)d]

Let's use this formula to calculate the sum of the following sequence of numbers that starts with -5, has a common difference of 7, and ends with 65. So, a = -5, d = 7, and the last term is 65, which means n = ?

To find 'n', we'll need to use the formula for the nth term in the sequence. The formula is as follows:a + (n-1)d = 65

Substituting the values of a and d, we get:-5 + (n-1)7 = 65Solving for n, we get:n = (65 + 5)/7n = 10

Using the formula for the sum of n terms, we get:

Sum of n terms = (n/2)[2a + (n - 1)d]Sum of 10 terms = (10/2)[2(-5) + (10-1)7]

Sum of 10 terms = (5)(-10 + 63)Sum of 10 terms = (5)(53)Sum of 10 terms = 265

Therefore, the sum using sigma notation starting from i = 1, is as follows:∑i=1^10 ( -5 + (i-1)7 ).

The measures of ∠ABD and ∠DBE are 76° and 104°

Given, ∠ABE = 180°

∠ABC + ∠CBE = ∠ABE

3x+5 + 2x+10 = 180

5x + 15 = 180

5x = 165

x = 165/5 = 33

∠ABD = ∠CBE     (Vertically opposite angles)

Vertically opposite angles are a pair of angles that are opposite each other when two lines intersect. These angles are formed by two intersecting lines and share the same vertex but are on opposite sides of the intersection. Vertically opposite angles are congruent, which means they have equal measures or angles.

Given question is incomplete, the complete question is below

Angle ABE measures 180°. Find the measures of angle ABD and angle DBE.

Answer:

true

Step-by-step explanation:

<3

Answer:

between 10 and 12

Step-by-step explanation:

Given the measure of angles:

m∠B = 70°

m∠C = 60°

m∠A = 50°

Following this information, since the side lengths are directly proportional to the angle measure they see:

Angle B is the largest angle. Therefore, side AC is the longest side of the triangle since it is opposite of the largest angle.

Angle C is the smallest angle, so the side AB is the shortest side.

Therefore, side BC must be between 10 and 12 inches.

There are no specific points on the surface 5x^2 + 3y^2 + 2z^2 = 1 at which the tangent plane is parallel to the plane -4x + 4y + 5z = 0. The entire surface is parallel to the given plane.

To find the points on the surface 5x^2 + 3y^2 + 2z^2 = 1 at which the tangent plane is parallel to the plane -4x + 4y + 5z = 0, we need to determine the normal vector of the surface and the normal vector of the given plane.

Let's start by finding the normal vector of the given plane. The coefficients of x, y, and z in the equation -4x + 4y + 5z = 0 represent the components of the normal vector. Therefore, the normal vector of the plane is n1 = (-4, 4, 5).

Next, we need to find the normal vector of the surface 5x^2 + 3y^2 + 2z^2 = 1. To do this, we differentiate the equation implicitly with respect to x, y, and z.

Differentiating the equation with respect to x:

d/dx(5x^2) + d/dx(3y^2) + d/dx(2z^2) = d/dx(1)

10x + 0 + 0 = 0

10x = 0

x = 0

Differentiating the equation with respect to y:

d/dy(5x^2) + d/dy(3y^2) + d/dy(2z^2) = d/dy(1)

0 + 6y + 0 = 0

6y = 0

y = 0

Differentiating the equation with respect to z:

d/dz(5x^2) + d/dz(3y^2) + d/dz(2z^2) = d/dz(1)

0 + 0 + 4z = 0

4z = 0

z = 0

Therefore, the normal vector of the surface at the point (0, 0, 0) is n2 = (0, 0, 0). However, since the magnitude of the normal vector is zero, it indicates that the surface does not have a unique normal vector at the point (0, 0, 0).

Since the tangent plane is parallel to the given plane, the normal vectors of the surface and the plane must be parallel. Thus, the normal vectors n1 and n2 must be parallel.

To check if n1 and n2 are parallel, we can take the cross product of n1 and n2 and see if the resulting vector is the zero vector.

n1 x n2 = (-4, 4, 5) x (0, 0, 0)

= (0, 0, 0)

The resulting vector is indeed the zero vector, which means that n1 and n2 are parallel. Therefore, the tangent plane to the surface 5x^2 + 3y^2 + 2z^2 = 1 is parallel to the plane -4x + 4y + 5z = 0 at all points on the surface.

In summary, there are no specific points on the surface 5x^2 + 3y^2 + 2z^2 = 1 at which the tangent plane is parallel to the plane -4x + 4y + 5z = 0. The entire surface is parallel to the given plane.

a. the value of c is 2. b. the probability P(X < 1, Y < 1) is given by 1 - e^-1 - e^-2 + e^-3. c. P(X > Y ) is  (-e^(-x-2y) + e^(-2y)y) + e^(-2y) - e^(-2y)y.

a. Finding the value of c:

To find the value of c, we need to integrate the joint probability density function (PDF) over the entire range of x and y and set it equal to 1, since the PDF must satisfy the normalization condition.

The joint PDF is given by f(x, y) = ce^(-x-2y)

∫∫f(x, y) dx dy = 1

∫∫ce^(-x-2y) dx dy = 1

Integrating with respect to x first:

∫[0,∞] ce^(-x-2y) dx = [-ce^(-x-2y)] [0,∞] = ce^(-2y)

Integrating the result with respect to y:

∫[0,∞] ce^(-2y) dy = [-1/2 * ce^(-2y)] [0,∞] = 1/2

Setting this equal to 1:

1/2 = 1/c

Solving for c:

c = 2

Therefore, the value of c is 2.

b. Calculating P(X < 1, Y < 1):

To find the probability P(X < 1, Y < 1), we need to integrate the joint PDF over the given region.

P(X < 1, Y < 1) = ∫[0,1] ∫[0,1] 2e^(-x-2y) dx dy

Integrating this expression, we get:

P(X < 1, Y < 1) = ∫[0,1] [-2e^(-x-2y)] [0,1] dy

= ∫[0,1] -2e^(-1-2y) + 2e^(-2y) dy

= [-e^(-1-2y) + e^(-2y)] [0,1]

= (-e^(-1-2) + e^(-2)) - (-e^(-1) + e^0)

= (-e^-3 + e^-2) - (-e^-1 + 1)

= 1 - e^-1 - e^-2 + e^-3

Therefore, the probability P(X < 1, Y < 1) is given by 1 - e^-1 - e^-2 + e^-3.

c. Finding P(X > Y):

To find the probability P(X > Y), we need to integrate the joint PDF over the region where X > Y.

P(X > Y) = ∫[0,∞] ∫[y,∞] 2e^(-x-2y) dx dy

Integrating this expression, we get:

P(X > Y) = ∫[0,∞] [-e^(-x-2y)] [y,∞] dy

= ∫[0,∞] -e^(-x-2y) + e^(-2y)y dy

= [-e^(-x-2y) + e^(-2y)y] [y,∞]

= (-e^(-x-2y) + e^(-2y)y) - (-e^(-2y) + e^(-2y)y)

= (-e^(-x-2y) + e^(-2y)y) + e^(-2y) - e^(-2y)y

The volume of the solid is approximately V ≈ 1.062 cubic units.

We have,

To find the volume of the solid formed by revolving region R around the vertical line x = 1, we can use the method of cylindrical shells.

The volume of the solid can be obtained by integrating the area of each cylindrical shell.

Each shell is formed by taking a thin vertical strip of width dx from region R and rotating it around the line x = 1.

Let's denote the radius of each cylindrical shell as r(x), where r(x) is the distance from the line x = 1 to the curve y = tan(x).

Since the shell is formed by revolving the strip around x = 1, the radius of the shell is given by r(x) = 1 - x.

The height of each cylindrical shell is the difference in y-values between the curve y = tan(x) and the x-axis, which is given by y(x) = tan(x).

The differential volume of each cylindrical shell is given by

dV = 2π r(x) y(x) dx.

To find the total volume of the solid, we integrate the differential volume over the interval where region R exists, which is from x = 0 to x = 1.

Therefore, volume V is given by the integral:

V = ∫[0,1] 2π x (1 - x) x tan(x) dx

To solve this integral, we can use integration techniques or numerical methods.

Using numerical approximation, the volume is approximately V ≈ 1.062 cubic units.

The particular solution of y''' = 0, with initial conditions y(0) = 3, y'(1) = 4, y''(2) = 6, is y(x) = 3x² - 2x + 3.

To find the particular solution of the differential equation y''' = 0, we need to integrate the equation multiple times. Let's proceed step by step:

First, integrate the equation y''' = 0 with respect to x to obtain y''(x):

∫(y''') dx = ∫(0) dx

y''(x) = C₁

Here, C₁ is the constant of integration.

Integrate y''(x) = C₁ with respect to x to find y'(x):

∫(y'') dx = ∫(C₁) dx

y'(x) = C₁x + C₂

Here, C₂ is the constant of integration.

Integrate y'(x) = C₁x + C₂ with respect to x to determine y(x):

∫(y') dx = ∫(C₁x + C₂) dx

y(x) = (C₁/2)x² + C₂x + C₃

Here, C₃ is the constant of integration.

Now, we can apply the given initial conditions to find the particular solution:

Using y(0) = 3:

y(0) = (C₁/2)(0)² + C₂(0) + C₃ = 0 + 0 + C₃ = C₃ = 3

Using y'(1) = 4:

y'(1) = C₁(1) + C₂ = C₁ + C₂ = 4

Using y''(2) = 6:

y''(2) = C₁ = 6

From the equation C₁ + C₂ = 4, and substituting C₁ = 6, we can solve for C₂:

6 + C₂ = 4

C₂ = 4 - 6

C₂ = -2

Therefore, C₁ = 6, C₂ = -2, and C₃ = 3. Plugging these values back into the equation y(x), we obtain the particular solution:

y(x) = (6/2)x² - 2x + 3

y(x) = 3x² - 2x + 3

Hence, the particular solution of the given differential equation y''' = 0, satisfying the initial conditions y(0) = 3, y'(1) = 4, y''(2) = 6, is y(x) = 3x² - 2x + 3.
