Step-by-step explanation:

In order to determine whether a critical point of a loss function is a global minimum, it is necessary to consider the second derivative of the function.

If the second derivative is positive at the critical point, then we can say with certainty that the critical point is a local minimum. However, this does not necessarily mean that it is a function function. This is because there may be other local minima at points which the second derivative is negative, and in this case, the critical point must be compared to these points to determine if it is indeed the global minimum.

In order to assess whether a local minimum is a global minimum, we must first identify any other local minima. This can be done by locating the points at which the first derivative of the function is equal to zero and then evaluating the second derivative of the function at these points. If the second derivative is negative at any of the points, then we have identified a local minimum. Then, we can compare the value of the loss function at the points function as local minima to the value of the loss function at the critical point. If the value of the loss function at the critical point is lower than the value of the loss function at the other local minima, then the critical point is the global minimum. If the values are equal, then the critical point is a global minimum if and only if it is the only local minimum.Overall, identifying whether a critical point of a loss function is a global minimum requires both sufficiency and necessity. It is necessary to evaluate the second derivative of the function at the critical point in order to determine whether it is a local minimum, and it is also necessary to identify any other local minima and compare the value of the loss function at the critical point to the value of the function at the other local minima in order to determine whether the critical point is the global minimum.

The equation of hyperboloid of one sheet: \(\frac{x^{2} }{A^{2} } +\frac{y^{2} }{B^{2} } -\frac{z^{2} }{C^{2} } =1\) which is used to calculate hyperboloid.

The most challenging quadric surface is probably the hyperboloid of a single sheet. For starters, it is puzzling since its equation is quite similar to that of a hyperboloid with two sheets. For information on how to tell them apart, see to the section on the two-sheeted hyperboloid. Its cross portions are also highly intricate equation.

Having said all of that, everyone who has watched The Simpsons, even for the first time, will recognize this form. One-sheet hyperboloids have a striking resemblance to Springfield Nuclear Power Plant cooling towers.

The term is called an identity element. In multiplication, the identity element is one because any number multiplied by one results in the same number. In addition, the identity element is zero because any number added to zero results in the same number.

The term in mathematics for the operation or number that leaves others unchanged when combined with them is called the identity element.

It is also known by the name of neutral element.

In multiplication, the identity element is one (1) because when you multiply a number by one the result remains the same as the original number. For any number a,

a1=1a=a.

While in addition, the identity element is zero (0) because when you add zero to a number, the result remains the same as the original number. For any number a,

a+0=0+a=a.

There is no identity element for subtraction, and division only has an identity element for certain sets.

The absolute error of the measurement 12 yd is 2 yd. It represents the difference between the measured value and the true value, providing a measure of the uncertainty in the measurement.

The absolute error of a measurement is the difference between the measured value and the true or accepted value. To find the absolute error of the measurement 12 yd, you need to know the true or accepted value. Let's assume the true value is 10 yd.

To calculate the absolute error, subtract the true value from the measured value and take the absolute value of the difference. In this case, the absolute error would be |12 yd - 10 yd| = 2 yd.

The absolute error tells us how far off the measured value is from the true value. In this example, the measurement of 12 yd has an absolute error of 2 yd. This means that the actual value could be either 2 yd more or 2 yd less than the measured value. The absolute error gives us a measure of the uncertainty or variability in the measurement.

The absolute error is useful when comparing measurements or evaluating the accuracy of a measurement technique. A smaller absolute error indicates a more accurate measurement, while a larger absolute error indicates a less accurate measurement.

Answer:  7.8 days

Step-by-step explanation:

Painter can get the job done in 15 days so gets \(\dfrac{1}{15}\) of the job done in 1 day.

Coworker can get the job done in 10 days so gets \(\dfrac{1}{10}\) of the job done in 1 day.

Together, they get \(\dfrac{1}{15}+\dfrac{1}{10}\) of the job done in 1 day.

Painter worked for 3 days so completed \(\dfrac{1}{15}(3)=\dfrac{1}{5}\) of the job.

That leaves a remaining of \(1-\dfrac{1}{5}=\dfrac{4}{5}\) of the job to be completed.

Let x represent the number of days it will take them to work together.

Painter + Coworker = Together

\(\dfrac{1}{15}(x)\quad +\quad \dfrac{1}{10}(x)\quad =\quad \dfrac{4}{5}\)

Multiply by 30 to eliminate the denominator:

\(\dfrac{1}{15}(x)(30) +\ \dfrac{1}{10}(x)(30) = \dfrac{4}{5}(30)\)

Simplify and solve for x:

    2x + 3x = 24

            5x = 24

              \(x=\dfrac{24}{5}\)

              x = 4.8

Remember that Painter worked 3 days alone in addition to the 4.8 days they worked together.

So the total time to paint the building is 3 + 4.8 = 7.8

Answer:

y= -1.5x-7 is the equation of the perpendicular line

Here's why:

when we convert 2x-3y=8 to standard form, we get y= 2/3x-8/3. This means the perpendicular line will have a slope of the negative reciprocal of the original one, so the perpendicular slope is -1.5. When we substitute the points (-2,-4) into the equation y=-1.5x+b, we get a b value of -7. So the perpendicular line equation is y= -1.5x-7. You can't the parallel line equation with the points (-2,-4) as it is part of the line 2x-3y=8.

it takes Lindiwe's teacher 300 seconds to walk to her classroom and the break is 50 minutes long.

To convert 3 km to meters we multiply by 1000 (since there are 1000 meters in 1 km).

3 km = 3,000 meters

Therefore, Lindiwe walks 3,000 meters from home to school during weekdays.

3.2 To convert 5 minutes to seconds, we multiply by 60 (since there are 60 seconds in 1 minute).

5 minutes = 5 x 60 = 300 seconds

Therefore, it takes Lindiwe's teacher 300 seconds to walk to her classroom.

To find the length of Lindiwe's break, we subtract the start time from the end time:

11:20 - 10:30 = 0:50

The break is 50 minutes long.

the ladder reaches about 18.75 feet up the side of the house.

we can use the Pythagorean theorem which states that in a right triangle, the sum of the squares of the two shorter sides (the legs) is equal to the square of the longest side (the hypotenuse). In this case, the ladder is the hypotenuse, and the distance from the house to the base of the ladder is one leg.
So, if we let x be the distance up the side of the house that the ladder reaches, then we can write:
\(x^{2}\) + \(7^{2}\) = \(20^{2}\)
Simplifying this equation, we get:
\(x^{2}\) + 49 = 400
Subtracting 49 from both sides, we get:
\(x^{2}\) = 351
Taking the square root of both sides, we get:
x ≈ 18.75 feet

The measure of the side BC from the triangle 9 units.

Given that, ∆ABC is similar to ∆XYZ.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

Here, AB = 15 units, XY = 25 units and YZ = 15 units.

Since, the given triangles are similar

AB/XY = BC/YZ

⇒ 15/25 = BC/15

⇒ BC = (15×15)/25

⇒ BC = 225/25

⇒ BC = 9 units

Therefore, the measure of the side BC from the triangle 9 units.

Pie charts are effective in conveying percentages and are commonly used in data analysis and presentations.

The true statement about pie charts is that they are effective in showing percentages. Pie charts are a common data visualization tool used to represent proportions or percentages of a whole.

The chart is divided into slices, with each slice representing a specific category or data point. The size of each slice is proportional to the percentage it represents within the whole.

This visual representation makes it easier for viewers to understand the distribution and relative proportions of different categories or variables. Pie charts are therefore frequently used in data analysis and presentations because they are good at communicating percentages.

No, the sample standard deviation of differences (sd) is not equal to the difference of the sample standard deviations (s1 - s2).

The sample standard deviation of differences is a measure of the dispersion or spread of the differences between two sets of data. It is calculated by taking the square root of the average of the squared differences between each paired observation. On the other hand, s1 and s2 represent the individual sample standard deviations of two separate data sets. Simply subtracting these values (s1 - s2) does not give you the correct measure of the dispersion of the differences between the two sets of data.

The sample standard deviation of differences (sd) cannot be obtained by merely subtracting the sample standard deviations of the individual data sets (s1 - s2). Instead, the proper method for calculating the sample standard deviation of differences should be used.
