Comparing the total run time of Newton's method and SGD depends on the specific problem and the convergence properties of the algorithms. While Newton's method may converge faster per iteration, it can be more computationally expensive.

When comparing the total run time of Newton's method and stochastic gradient descent (SGD) for optimizing the same problem, we need to consider their convergence properties and computational efficiency.

Newton's method is a deterministic optimization algorithm that uses the second derivative (Hessian matrix) to find the minimum of a function. It usually converges faster than SGD, especially when the function is smooth and has well-behaved derivatives.

However, Newton's method can be computationally expensive for large-scale problems since it requires computing and inverting the Hessian matrix, which can be time-consuming and memory-intensive.

On the other hand, SGD is an iterative optimization algorithm commonly used in machine learning. It randomly selects a subset of training samples (mini-batch) at each iteration and updates the model parameters based on the gradient of the objective function.

SGD is particularly useful for large-scale problems as it only requires the calculation of the gradient, which can be done efficiently. However, SGD usually converges more slowly than Newton's method due to the noise introduced by the random sampling of the mini-batches.

If both algorithms eventually converge to the global minimizer, the total run time will depend on the specific problem and the convergence rates of the algorithms.

In general, Newton's method may require fewer iterations to converge but each iteration can be more computationally expensive.

On the other hand, SGD may require more iterations but each iteration is computationally cheaper. Therefore, the trade-off between the number of iterations and computational cost will determine the total run time.

We are given the following absolute value equation

Let us solve the problem then we will compare it with the given solution.

Now we will solve for the positive and negative sign separately

Comparing it with the given solution, there is an error on the left-hand side step 2. (the sign of 38 should be positive but in the figure, it is shown negative)

Now let us substitute the obtained x values into the original absolute value equation and check if they satisfy the equation.

For x = -4:

Hence, x = -4 is a valid solution.

For x = -38:

Hence, x = -38 is not a valid solution.

The above is an example of an extraneous solution.

An extraneous solution is a solution that we get during the process of solving an equation but it is not really the solution meaning that it does not satisfy the equation!

Therefore, x = -4 is the only solution to the given equation.

Answer:  approximately 24 square units in the shaded areas

Step-by-step explanation:  

The area of the entire dark circles will be for each πr², then divided by 2 to get the area of the semicircles created on the sides of the triangles:

16π + 9π = 25π   Half that times value for pi

≈ 39.2699  is the area of the dark semicircles. Round to 39.27

Now the fun! Find the area of the parts subtracted by the light semicircle:

The area of the entire circle is 25π  or about 78.54. The triangle is half of an inscribed rectangle, 6×8, so 48.  Subtracted from the circle leaves about 30.54 in the four slices between the arcs of the circumference and the perimeter of the rectangle. We are concerned with only half of the slices, so we will subtract 15.27

Area of the dark semicircles minus the area of the light slices will leave the area of the shaded crescents:

The radius of a cylinder is 4 inches and the height is 5 inches. The surface area is equal to the sum of the areas of all the faces of a solid.

A cylinder has two circular bases, and each circular base has an area of πr² square units, where r is the radius of the base. The lateral area of a cylinder is the area of the cylinder's curved surface, which is the height of the cylinder multiplied by the cylinder's base perimeter. It is given by the formula: 2πrh. The surface area of the cylinder is obtained by summing the lateral area and two times the area of the base. Hence, we have:

Surface area = 2πrh + 2πr²

Let us calculate the area of the two bases by plugging the given values into the formula.

Area of one base = πr²= π (4)²= 16π square inches

Therefore, the area of the two bases is 2 × 16π = 32π square inches. Thus, statement 2 is correct

Lateral area of a cylinderLateral area = 2πrh= 2 × π × 4 × 5= 40π square inches.

Thus, statement 3 is correct.

The total surface area of the cylinderTotal surface area = Lateral area + 2 × Area of base= 2πrh + 2 × πr²= 2πr(h + r)= 2π × 4(5 + 4)= 72π square inches.

Therefore, statement 5 is correct.

Therefore, the following statements are correct:Statement 2: The area of the two bases is 32π square inches.Statement 3: The lateral area is 40π square inches.Statement 5: The total surface area is 72π square inches are true.Therefore, the correct statements are 2, 3, and 5.

So,

The square pyramid is having a height of 89 units.

A pyramid is a three-dimensional shape. A pyramid's flat triangular faces unite at a common point known as the apex and have a polygonal base. The bases are joined to the peak to create a pyramid.

As per the given data:

length of the base (\(a\)) = 20.8 units

slant height of the pyramid (\(s\)) = 89.6 units

Height of the pyramid (\(H\)) = \(\sqrt{s^2 - (\frac{a}{2})^2}\)

=  \(\sqrt{(89.6)^2 - (\frac{20.8}{2})^2}\)

=  \(\sqrt{(89.6)^2 - (\frac{20.8}{2})^2}\)

=  \(\sqrt{(89.6)^2 - (10.4)^2}\)

=  \(\sqrt{(8028.16) - (108.16)}\)

= \(\sqrt{7920}\)

= \(89\) units

The height of the square pyramid is 89 units.

Answer:

Step-by-step explanation:

Formula for perimeter of a rectangle = 2l +2w

where L= length ,w= width /breadth

Now;

with the question the length and width is unknown but the width is 12cm less than the length so;

width =( L -12cm )

Also the length is not given so remains L

Using the formula

2l + 2w

= 2l + 2( l- 12cm )

This must be equated to the perimeter

So;

2l + 2(l- 12cm ) = 156

2l + 2l -24cm = 156

4l = 156 +24

4l = 180

l = 45cm

therefore the length is 45cm

The width can be gotten by using the guideline provided which is, (L -12cm)

placing L which is already known

= (45-12)

= 33cm

therefore the width is 33cm

Step-by-step explanation:

Dominik used 7/8 cup of sugar for a bread recipe. he used 3/4 cup of sugar for a muffin recipe.

To find out how much sugar Dominik used in total for both recipes, we need to add the amounts of sugar he used in each recipe.

7/8 cup + 3/4 cup

To add these two fractions, we need to find a common denominator. In this case, the smallest common denominator is 8, which is the same as the denominator of the first fraction.

7/8 cup + 3/4 cup = (7/8) cup + (6/8) cup

Now we can add the two numerators

(7/8) cup + (6/8) cup = 13/8 cup
Hence, Dominik used 13/8 cups of sugar for both recipes combined.

A ternary string is a string composed of characters 0, 1, and 2. The number of ternary strings that contain exactly n characters, each of which is one of three types, is 3^n.Exactly 5 0s, 5 1s, and 5 2s are required for the ternary string, which means that the total number of characters is 15.

Each of these characters can be one of three types (0, 1, or 2). As a result, the total number of possible strings is 3^15. This is equivalent to 14,348,907. We arrived at this conclusion by computing 3 to the fifteenth power.Explanation:When constructing a sequence of three symbols, the first symbol has three alternatives, the second symbol has three alternatives, and so on. There are n choices for each of the n characters, resulting in a total of 3^n possible sequences.Example 1:Let's assume we have to create 5-character sequences with three symbols: a, b, and c. There are 3*3*3*3*3 = 243 possible sequences since there are three choices for each symbol.Example 2:Let's assume we have to construct a 10-character sequence using three symbols: 0, 1, and 2. There are 3*3*3*3*3*3*3*3*3*3 = 59,049, a total of 59,049 possible 10-character sequences. We can perform the same calculation for 15-character strings using the same logic.

Answer:

y = -3/5x + 4

Explanation:

Slope intercept form: y = mx + b

m = slope

b = y-int

~ fill in the formula ~

y = (slope)x + y-intercept

y = (-3/5)x + 4

Final equation: y = -3/5x + 4

Answer: To write the equation of a line parallel to AB through a given point, we need to follow these steps:

Find the slope of the line AB. The slope of a line passing through two points (x1, y1) and (x2, y2) is given by the formula:

m = (y2 - y1)/(x2 - x1)

Let the coordinates of points A and B be (x1, y1) and (x2, y2) respectively. Then, the slope of the line AB is:

m = (y2 - y1)/(x2 - x1)

Since we want to find the equation of a line parallel to AB, the slope of this line will also be equal to m.

Let the given point be (x0, y0). Using the point-slope form of the equation of a line, we can write the equation of the line passing through (x0, y0) with slope m as:

y - y0 = m(x - x0)

Substituting the value of m found in step 1, we get:

y - y0 = (y2 - y1)/(x2 - x1) * (x - x0)

This is the equation of the line parallel to AB passing through the point (x0, y0).

Note that we assume that the line passing through A and B exists and is not vertical. If the line is vertical, then its slope is undefined, and we cannot find the equation of a parallel line using this method. In that case, we need to use a different method to find the equation of the line.
