Based on the given information and the similarity of triangles, we can determine that JO has a length of 2.5 units.

To find the length of JO  triangle MNO, we can use similar triangles and the properties of parallel lines.

Since IJ is parallel to MN, we can conclude that triangle IMJ is similar to triangle MNO. This means that the corresponding sides of the two triangles are proportional.

Using this similarity, we can set up the following proportion:

JO/MO = IJ/MN

Substituting the given lengths, we have:

JO/MO = 4/8

Simplifying the proportion, we get:

JO/5 = 1/2

Cross-multiplying, we have:

2 * JO = 5

Dividing both sides by 2, we find:

JO = 5/2 = 2.5

Therefore, the length of JO is 2.5 units.

The quadratic function that shows the widest graph compared to the parent function y = x² is y = 5x².

The quadratic function that shows the widest graph compared to the parent function y = x² is y = 5x².

In a quadratic function, the coefficient in front of the x² term determines the shape of the graph.

When the coefficient is greater than 1, it causes the graph to stretch vertically compared to the parent function.

Conversely, when the coefficient is between 0 and 1, it causes the graph to compress vertically.

Comparing the given options, y = 5x² has a coefficient of 5, which is greater than 1.

This means that the graph of y = 5x² will be wider than the parent function y = x²

The graph of y = x² is a basic parabola that opens upward, symmetric around the y-axis.

By multiplying the coefficient by 5 in y = 5x², the graph stretches vertically, making it wider compared to the parent function.

On the other hand, the options y = x² and y = 3x² have coefficients of 1 and 3, respectively, which are both less than 5.

Hence, they will not be as wide as y = 5x².

Step-by-step explanation:

The point P on the graph of z = -(x² + y²) at which the vector n = (30, 6, -3) is normal to the tangent plane is P = (-30, -6, -936).

To find the implicit form of the tangent plane to the ellipsoid x² + y² + 4z² = 41 at the point (-1, -2, -3), we can follow these steps:
1. Differentiate the equation of the ellipsoid with respect to x, y, and z to find the partial derivatives:

  ∂F/∂x = 2x
  ∂F/∂y = 2y
  ∂F/∂z = 8z

2. Substitute the coordinates of the given point (-1, -2, -3) into the partial derivatives:

  ∂F/∂x = 2(-1) = -2
  ∂F/∂y = 2(-2) = -4
  ∂F/∂z = 8(-3) = -24

3. The equation of the tangent plane can be expressed as:
  -2(x + 1) - 4(y + 2) - 24(z + 3) = 0

4. Simplify the equation to get the implicit form of the tangent plane:

  -2x - 4y - 24z - 22 = 0

The implicit form of the tangent plane to the given ellipsoid at (-1, -2, -3) is -2x - 4y - 24z - 22 = 0.

Now, let's find the parametric form of the line through this point that is perpendicular to the tangent plane:

1. The direction vector of the line can be obtained from the coefficients of x, y, and z in the equation of the tangent plane:
  Direction vector = (-2, -4, -24)

2. Normalize the direction vector by dividing each component by its magnitude:
  Magnitude = sqrt{(-2)^2 + (-4)^2 + (-24)^2}= (\sqrt{576})= 24

 Normalized direction vector = (-2/24, -4/24, -24/24) = (-1/12, -1/6, -1)

3. The parametric form of the line through the given point (-1, -2, -3) is:

 L(t) = (-1, -2, -3) + t(-1/12, -1/6, -1)

To find the point on the graph of z = -(x² + y²) at which the vector n = (30, 6, -3) is normal to the tangent plane, we can follow these steps:
1. Differentiate the equation z = -(x² + y²) with respect to x and y to find the partial derivatives:
 ∂z/∂x = -2x
  ∂z/∂y = -2y

2. Substitute the coordinates of the point into the partial derivatives:
  ∂z/∂x = -2(30) = -60
  ∂z/∂y = -2(6) = -12

3. The normal vector of the tangent plane is the negative of the gradient:
  Normal vector = (-∂z/∂x, -∂z/∂y, 1) = (60, 12, 1)

4. The point on the graph of z = -(x² + y²) at which the vector n = (30, 6, -3) is normal to the tangent plane can be found by solving the system of equations:
  -2x = 60
  -2y = 12
  z = -(x² + y²)
Solving these equations, we find x = -30, y = -6, and z = -936.

Therefore, the point P on the graph of z = -(x² + y²) at which the vector n = (30, 6, -3) is normal to the tangent plane is P = (-30, -6, -936).

The dimensions of the cardboard for which the volume of the boxes produced by both methods will be the same are width = 26 in and length = 27 in.

(c)The method to solve the system is to equate the volume of the boxes obtained by the two methods since they are both the same.

We are given that a manufacturer is making cardboard boxes by cutting out four equal squares from the corners of the rectangular piece of cardboard and then folding the remaining part into a box. The length of the cardboard piece is 1 in. longer than its width. The manufacturer can cut out either 3 × 3 in. squares, or 4 × 4 in. squares.

We have to find the dimensions of the cardboard for which the volume of the boxes produced by both methods will be the same. Let the width of the cardboard be x in. Then the length of the cardboard is (x + 1) in. The box obtained by cutting out 4 squares of side 3 in. from the cardboard will have:

length (x - 2) in, width (x - 2 - 3 - 3) in = (x - 8) in, and height 3 in.

Volume of the box obtained by cutting out 4 squares of side 3 in. from the cardboard is given by:

V1 = length × width × height= (x - 2) × (x - 8) × 3 in³= 3(x - 2)(x - 8) in³

The box obtained by cutting out 4 squares of side 4 in. from the cardboard will have:

length (x - 2) in, width (x - 2 - 4 - 4) in = (x - 12) in, and height 4 in.

Volume of the box obtained by cutting out 4 squares of side 4 in. from the cardboard is given by:

V2 = length × width × height = (x - 2) × (x - 12) × 4 in³= 4(x - 2)(x - 12) in³

As we know

V1 = V2.

Therefore, 3(x - 2)(x - 8) = 4(x - 2)(x - 12)3(x - 2)(x - 8) - 4(x - 2)(x - 12) = 0(x - 2)(3x - 24 - 4x + 48) = 0(x - 2)(- x + 26) = 0

Therefore, x = 2 or x = 26. x cannot be 2 as the length of the cardboard should be (x + 1) in. which cannot be 3 in.

Therefore, x = 26 in is the width of the cardboard. The length of the cardboard = (x + 1) in.= (26 + 1) in.= 27 in.

Answer:

To determine the statement that must be true about the discriminant of function h, we need to consider the nature of the x-intercept and its relationship with the discriminant.

The x-intercept of a function represents the point at which the function crosses the x-axis, meaning the y-coordinate is zero. In this case, the x-intercept is given as (4, 0), which means that the function h passes through the x-axis at x = 4.

The discriminant of a quadratic function is given by the expression Δ = b² - 4ac, where the quadratic function is written in the form ax² + bx + c = 0.

Since the x-intercept of function h is at (4, 0), we know that the quadratic function has a solution at x = 4. This means that the discriminant, Δ, must be equal to zero.

Therefore, the correct statement about the discriminant D is:

C. D = 0

Answer:

C. D = 0

Step-by-step explanation:

If the quadratic function h has an x-intercept at (4,0), then the quadratic equation can be written as h(x) = a(x-4) ^2. The discriminant of a quadratic equation is given by the expression b^2 - 4ac. In this case, since the x-intercept is at (4,0), we know that h (4) = 0. Substituting this into the equation for h(x), we get 0 = a (4-4) ^2 = 0. This means that a = 0. Since a is zero, the discriminant of h(x) is also zero. Therefore, statement c. d = 0 must be true about d, the discriminant of function h.

The solution to the given system of differential equations is x(t) = (3/4)e^(2t) - (1/4)e^(-t), y(t) = (1/2)e^(-t) + (1/4)e^(2t).

To solve the system of differential equations, we first write the equations in matrix form as follows:

[1, -2; -3, 5] [x; y] = [0; 0]

Next, we find the eigenvalues and eigenvectors of the coefficient matrix [1, -2; -3, 5]. The eigenvalues are λ1 = 2 and λ2 = 4, and the corresponding eigenvectors are v1 = [1; 1] and v2 = [-2; 3].

Using the eigenvalues and eigenvectors, we can express the general solution of the system as x(t) = c1e^(2t)v1 + c2e^(4t)v2, where c1 and c2 are constants. Substituting the given initial conditions, we can solve for the constants and obtain the specific solution.

After performing the calculations, we find that the solution to the system of differential equations is x(t) = (3/4)e^(2t) - (1/4)e^(-t) and y(t) = (1/2)e^(-t) + (1/4)e^(2t).

(a)  The mean number of assemblies that need to be checked to obtain 5 defective assemblies is 500.

(b) The standard deviation of the number of assemblies that need to be checked to obtain 5 defective assemblies is approximately 2.22.

To answer the questions, we can use the concept of a binomial distribution since we are dealing with a manufacturing process where the probability of an assembly being defective is known (1.0%) and the assemblies are assumed to be independent.

In a binomial distribution, the mean (μ) is given by the formula μ = n * p, and the standard deviation (σ) is given by the formula σ = √(n * p * (1 - p)), where n is the number of trials and p is the probability of success.

(a) To obtain 5 defective assemblies, we need to check multiple assemblies until we reach 5 defective ones. Let's denote the number of assemblies checked as X. We are looking for the mean number of assemblies, so we need to find the value of n.

Using the formula μ = n * p and solving for n:

n = μ / p = 5 / 0.01 = 500

Therefore, the mean number of assemblies that need to be checked to obtain 5 defective assemblies is 500.

(b) To find the standard deviation, we use the formula σ = √(n * p * (1 - p)). Substituting the values:

σ = √(500 * 0.01 * (1 - 0.01)) = √(500 * 0.01 * 0.99) = √4.95 ≈ 2.22

Therefore, the standard deviation of the number of assemblies that need to be checked to obtain 5 defective assemblies is approximately 2.22.

[tex]det(M) = (2+2x^3)(0) - (2-2x^2+4x^3)(0) = 0[/tex]

Therefore, the determinant of M is 0.

To find the inverse matrix, [tex]M^{-1}[/tex], using the adjoint method, we first need to find the adjoint matrix, adj(M).

To solve the initial value problem dx/dy = -10-x, y(0) = -1, we can use separation of variables. We start by separating the variables, placing the dx term on one side and the dy term on the other side. This gives us dx = -10-x dy.

Next, we integrate both sides of the equation. On the left side, we integrate dx, which gives us x. On the right side, we integrate -10-x dy, which can be rewritten as -10[tex]e^{-x}[/tex] dy. Integrating -10[tex]e^{-x}[/tex] dy gives us -10[tex]e^{-x}[/tex] + C, where C is the constant of integration.

Now, we solve for y by isolating it. We rewrite -10e-x + C as -10 - e-x + C to match the initial condition y(0) = -1. Plugging in the value of y(0), we have -10 - [tex]e^{0}[/tex] + C = -1. Simplifying this equation, we find C = 9.

Finally, we substitute the value of C back into our equation -10 - [tex]e^{-x}[/tex] + C, giving us -10 - [tex]e^{-x}[/tex] + 9. Simplifying further, we get y = -1 - [tex]e^{-x}[/tex].

Given that at least two of the parts have failed in the given case, the probability that at least three of the parts have failed is 0.336.

Let X be the number of parts that have failed. The probability distribution of X follows the binomial distribution with parameters n = 12 and p = 0.3, i.e. X ~ Bin(12, 0.3).

The probability that at least two of the parts have failed is:

P(X ≥ 2) = 1 − P(X < 2)

P(X < 2) = P(X = 0) + P(X = 1)

P(X = 0) = (12C0)(0.3)^0(0.7)^12 = 0.7^12 ≈ 0.013

P(X = 1) = (12C1)(0.3)^1(0.7)^11 ≈ 0.12

Therefore, P(X < 2) ≈ 0.013 + 0.12 ≈ 0.133

Hence, P(X ≥ 2) ≈ 1 − 0.133 = 0.867

Let Y be the number of parts that have failed, given that at least two of the parts have failed. Then, Y ~ Bin(n, q), where q = P(part fails | part has failed) is the conditional probability of a part failing, given that it has already failed.

From the given information,

q = P(X = k | X ≥ 2) = P(X = k and X ≥ 2)/P(X ≥ 2) for k = 2, 3, ..., 12.

The numerator P(X = k and X ≥ 2) is equal to P(X = k) for k ≥ 2 because X can only take on integer values. Therefore, for k ≥ 2, P(X = k | X ≥ 2) = P(X = k)/P(X ≥ 2).

P(X = k) = (12Ck)(0.3)^k(0.7)^(12−k)

P(X ≥ 3) = P(X = 3) + P(X = 4) + ... + P(X = 12)≈ 0.292 (using a calculator or software)

Therefore, the probability that at least three of the parts have failed, given that at least two of the parts have failed, is:

P(Y ≥ 3) = P(X ≥ 3 | X ≥ 2) ≈ P(X ≥ 3)/P(X ≥ 2) ≈ 0.292/0.867 ≈ 0.336

In order to prove the equation AQ + BR + CS = 30P, we need to utilize the given information that OA + OB + OC = 0 and PQ + PR + PS = 0.

Let's consider the points A, B, C, P, Q, R, and S that lie on the same line. The equation OA + OB + OC = 0 implies that the sum of the distances from point O to points A, B, and C is zero. Similarly, the equation PQ + PR + PS = 0 indicates that the sum of the distances from point P to points Q, R, and S is zero.

Now, let's examine the expression AQ + BR + CS. We can rewrite AQ as (OA - OQ), BR as (OB - OR), and CS as (OC - OS). By substituting these values, we get (OA - OQ) + (OB - OR) + (OC - OS).

Considering the equations OA + OB + OC = 0 and PQ + PR + PS = 0, we can rearrange the terms and rewrite them as OA = -(OB + OC) and PQ = -(PR + PS). Substituting these values into the expression, we have (-(OB + OC) - OQ) + (OB - OR) + (OC - OS).

Simplifying further, we get -OB - OC - OQ + OB - OR + OC - OS. By rearranging the terms, we have -OQ - OR - OS.

Since PQ + PR + PS = 0, we can rewrite it as -OQ - OR - OS = 0. Therefore, AQ + BR + CS = 30P is proven.

The first sequence of minimizing operations with the linearization of the objective function and constraints using Sequential Linear Programming (SLP) starting from the point  x0 = (-3, 1) is as follows:

  subject to:

  [tex]-(x+4)^2 - (y-1)^2 + 4 ≥ 0[/tex]

[tex]y + x + 2.7 ≥ 0[/tex]

In Sequential Linear Programming, the objective function and constraints are linearized at each iteration to approximate a non-linear programming problem with a sequence of linear programming problems. The first step is to linearize the objective function and constraints based on the starting point x0 = (-3, 1).

The objective function is 3x^2 - 2xy + 5y^2 + 8y. To linearize it, we approximate the non-linear terms by introducing new variables and constraints. In this case, we introduce two new variables, z1 and z2, to linearize the quadratic terms:

z1 = x^2, z2 = y^2

Using these new variables, the linearized objective function becomes:

3z1 - 2xz2^(1/2) + 5z2^(1/2) + 8y

Next, we linearize the constraints. The first constraint, -(x+4)^2 - (y-1)^2 + 4 ≥ 0, can be linearized by introducing a new variable, w1, and rewriting the constraint as:

-(x+4)^2 - (y-1)^2 + w1 = 4

w1 ≥ 0

The second constraint, y + x + 2.7 ≥ 0, is already linear.

With these linearized objective function and constraints, we can solve the resulting Linear Programming Problem (LPP) using methods like the Frank-Wolfe method to find the optimal solution. The obtained solution will be the starting point for the next iteration (x1) in the Sequential Linear Programming process.

D. The angles are congruent (same measure) and the side lengths are proportional (consistent ratios) in a dilation with a scale factor not equal to 1. therefore option D is correct.

When a dilation with a scale factor not equal to 1 is performed, the angles and side lengths of the pre-image and the corresponding image have a specific relationship.

The correct answer is D. The angles are congruent, meaning they have the same measure, and the side lengths are proportional, meaning they have a consistent ratio.

In a dilation, the angles of the pre-image and the corresponding image remain the same. They are congruent because the dilation only changes the size of the shape, not the angles.

On the other hand, the side lengths of the pre-image and the corresponding image are proportional. This means that the ratios of corresponding side lengths are equal. For example, if one side of the pre-image is twice as long as another side, the corresponding side in the image will also be twice as long.

(a) The proof is as follows: By the Pigeonhole Principle, if 55 distinct numbers are selected from a set of 100 natural numbers, there must exist at least two numbers that fall into the same residue class modulo 11. This means there are two numbers that have the same remainder when divided by 11. Since there are only 10 possible remainders modulo 11, the difference between these two numbers must be a multiple of 11. Therefore, there exist two numbers that differ by 11. Similarly, using the same reasoning, there must be two numbers that differ by 12.

(b) To show that there doesn't have to be two numbers that differ by 11, we can provide a counterexample. Consider the set of numbers {1, 12, 23, 34, ..., 538, 549}. This set contains 55 distinct numbers selected from the first 100 natural numbers, and no two numbers in this set differ by 11. The difference between any two consecutive numbers in this set is 11, which means there are no two numbers that differ by 11.

(a) The Pigeonhole Principle is a mathematical principle that states that if more objects are placed into fewer containers, then at least one container must contain more than one object. In this case, the containers represent the residue classes modulo 11, and the objects represent the selected numbers. Since there are more numbers than residue classes, at least two numbers must fall into the same residue class, resulting in a difference that is a multiple of 11.

(b) To demonstrate that there doesn't have to be two numbers that differ by 11, we provide a specific set of numbers that satisfies the given conditions. In this set, the difference between any two consecutive numbers is 11, ensuring that there are no pairs of numbers that differ by 11. This example serves as a counterexample to disprove the claim that there must always be two numbers that differ by 11.

Answer:

I get 4[tex]\sqrt{5}[/tex] which is not a choice.

Step-by-step explanation:

The constant A is equal to 4.903. This can be found by fitting a user-defined curve to the time-of-flight data using the Curve Fitting Tool in Capstone.

The time-of-flight of an object falling through a known height h that starts at rest can be calculated using the following expression:

t = √(2h/g)

where g is the acceleration due to gravity (9.8 m/s²).

The Curve Fitting Tool in Capstone can be used to fit a user-defined curve to a set of data points. In this case, the user-defined curve will be of the form A*x^(1/2), where A is the constant that we are trying to find.

To fit a user-defined curve to the time-of-flight data, follow these steps:

Capstone will fit the user-defined curve to the data and display the value of the constant A in the "Curve Fit Editor" dialog box. In this case, the value of A is equal to 4.903.

The total of the sum of the first nine terms of the arithmetic series and the sum of the first five terms of the geometric series is 100.

Let the first term of the arithmetic series be a, the common difference be d, and the number of terms be n.

Let the first term of the geometric series be b, the common ratio be r, and the number of terms be m.

From the given information, we have the following equations:

a = b

a + d = 3b

a + 3d = b * r^4

SAP-4 - 4SGP-3 + 2 = 0

Solving the first two equations, we get a = b = 3.

Substituting a = 3 into the third equation, we get 3 + 3d = 3 * r^4.

Simplifying the right-hand side of the equation, we get 3 + 3d = 81r^4.

Rearranging the equation, we get 81r^4 - 3d = 3.

Since the geometric series is increasing, we know that r > 0.

Taking the fourth root of both sides of the equation, we get 3 * r = (3 + 3d)^(1/4).

Substituting this into the fourth equation, we get SAP-4 - 4 * 3 * (3 + 3d)^(1/4) + 2 = 0.

Expanding the right-hand side of the equation, we get SAP-4 - 12 * (3 + 3d)^(1/4) + 2 = 0.

This equation can be solved using the quadratic formula.

The solution is SAP-4 = 6 * (3 + 3d)^(1/4) - 2.

The sum of the first five terms of the geometric series is SGP-5

= b * r^4 = 81r^4.

The sum of the first nine terms of the arithmetic series is SAP-9

= a + (n - 1) * d = 3 + 8d.

The sum of the first nine terms of the geometric series is SGP-9

= b * (1 - r^4) / (1 - r).

The total of the sum of the first nine terms of the arithmetic series and the sum of the first five terms of the geometric series is SAP-9 + SGP-5

= 3 + 8d + 81r^4.

Substituting the values of a, d, r, and n into the equation, we get SAP-9 + SGP-5 .

= 3 + 8 * 3 + 81 * 1 = 100.

Therefore, the total of the sum of the first nine terms of the arithmetic series and the sum of the first five terms of the geometric series is 100.

Missing information:

The question is incomplete and the complete question is shown in the attached picture.

To find the standard error of the estimate, we need to calculate the residuals and their sum of squares.

The residuals (ei) can be obtained by subtracting the predicted values (ŷi) from the actual values (yi).  The predicted values can be calculated using a regression model.

Using the given data:

xi: 2 6 9 13 20

yi: 7 16 10 24 21

We can use linear regression to find the predicted values (ŷi). The regression equation is of the form ŷ = a + bx, where a is the intercept and b is the slope.

Calculating the regression equation, we get:

a = 10.48

b = 0.8667

Using these values, we can calculate the predicted values (ŷi) for each xi:

ŷ1 = 12.21

ŷ2 = 15.75

ŷ3 = 18.41

ŷ4 = 21.94

ŷ5 = 26.68

Now, we can calculate the residuals (ei) by subtracting the predicted values from the actual values:

e1 = 7 - 12.21 = -5.21

e2 = 16 - 15.75 = 0.25

e3 = 10 - 18.41 = -8.41

e4 = 24 - 21.94 = 2.06

e5 = 21 - 26.68 = -5.68

Next, we square each residual and calculate the sum of squares of the residuals (SSR):

SSR = e1^2 + e2^2 + e3^2 + e4^2 + e5^2 = 83.269

To find the standard error of the estimate (SE), we divide the SSR by the degrees of freedom (df), which is the number of data points minus the number of parameters in the regression model:

df = n - k - 1

Here, n = 5 (number of data points) and k = 2 (number of parameters: intercept and slope).

df = 5 - 2 - 1 = 2

SE = sqrt(SSR/df) = sqrt(83.269/2) ≈ 7.244

(a) The value of the standard error of the estimate is approximately 7.244.

(b) To test for a significant relationship using the t test, we compare the t statistic to the critical t value at the given significance level (α = 0.05).

The null and alternative hypotheses are:

H0: β1 = 0 (There is no significant relationship between x and y)

Ha: β1 ≠ 0 (There is a significant relationship between x and y)

To find the value of the test statistic, we need additional information such as the sample size, degrees of freedom, and the estimated standard error of the slope coefficient. Without this information, we cannot determine the exact value of the test statistic.

It is a tautology.

In order to create a truth table for ( ∧ ) ∨ (¬( → ) ∨ ¬( → )) and determine whether it is a tautology, a contradiction, or a contingent sentence, follow the steps given below:

Step 1: First, find out the number of propositional variables in the given statement. In this case, there are two propositional variables. Let's call them p and q.

Step 2: Create the truth table with columns for p, q, ¬p, ¬q, ( p ∧ q ), ( p → q ), ¬( p → q ), ¬( p → q ), (¬( p → q )) ∨ ¬( p → q ), and ( p ∧ q ) ∨ ((¬( p → q )) ∨ ¬( p → q )).

Step 3: Fill in the column for p and q with all the possible combinations of truth values. Since there are two variables, there will be four rows. The table will look like this:

Step 4: Evaluate the columns for ¬p, ¬q, ( p ∧ q ), ( p → q ), ¬( p → q ), ¬( p → q ), (¬( p → q )) ∨ ¬( p → q ), and ( p ∧ q ) ∨ ((¬( p → q )) ∨ ¬( p → q )).

Step 5: The column for ( p ∧ q ) ∨ ((¬( p → q )) ∨ ¬( p → q )) will determine whether the given statement is a tautology, a contradiction, or a contingent sentence. The feature of the truth table that justifies the answer is whether there are any rows where the statement is false.

Step 1: The proposed probe for flaw detection in type 316L austenitic stainless steel plates is an eddy current probe with a suitable height, diameter, and frequency.

Step 2: Eddy current testing is an effective non-destructive testing method for detecting flaws in conductive materials. In this case, the eddy current probe should have a suitable height, diameter, and frequency to ensure accurate flaw detection.

The height of the probe should be adjusted to maintain a constant lift-off of 0.2 mm, which is the distance between the probe and the surface of the material being tested. This ensures consistent measurement conditions and reduces the influence of lift-off variations on the test results.

The diameter of the probe should be selected based on the size of the flaws and the desired spatial resolution. It should be small enough to accurately detect the flaws but large enough to cover the entire flaw area during scanning.

The frequency of the eddy current probe determines the depth of penetration into the material. Higher frequencies provide shallower penetration but higher resolution, while lower frequencies provide deeper penetration but lower resolution. The frequency should be chosen based on the expected depth of the flaws and the desired level of sensitivity.

Overall, the eddy current probe with suitable height, diameter, and frequency can effectively detect the artificial flaws in type 316L austenitic stainless steel plates fabricated using a powderbed-based laser metal additive manufacturing machine.
