What is the value of discriminant X² 4x +4 0?

Answers

The value of the discriminant of the given expression x² + 4x +40 = 0  is equal to -144.

As given in the question,

Given expression is equal to :

x² + 4x +40 = 0

Standard formula of the discriminant for the general quadratic equation

ax² + bx + c = 0 is given by :

Discriminant is represented by  'D'

D = b² - 4ac

Here b = 4 , a = 1 and c = 40

Substitute the value in the formula we get,

D = 4² - 4(1)(40)

⇒D = 16 - 160

⇒ D = -144

Therefore , the value of the discriminant of the given expression x² + 4x +40 = 0 is equal to -144.

A 100 meter dah i run on a track in the direction of the vector v = 2i6j. The wind velocity w i 5ij km/h. The rule ay that a legal wind peed meaured in the direction of the dah mut not exceed 5 km/hr. Will the race reult be diqualified due to an illegal wind? Jutify your anwer

Answers

The race result will not be disqualified due to an illegal wind.

In order to determine whether the wind velocity during the race was legal, we need to compare the wind velocity w to the legal wind speed limit of 5 km/hr. In this case, the wind velocity is given as 5ij km/h, which is purely vertical wind. The direction of the wind is not relevant in this case, since the race is run in the direction of the vector v, which is a purely horizontal direction. Since the wind velocity w is purely vertical and the race is run in a purely horizontal direction, the wind velocity w has no effect on the race result. Therefore, the race result will not be disqualified due to an illegal wind.

Answers

No, 4 is not a linear expression.

A linear expression is an algebraic expression involving two or more variables, where the highest power of each variable is one. Linear expressions can be written in the form of an equation, such as y = 2x + 5. In this equation, y and x are variables, and 2 and 5 are constants. The highest power of each variable is one, so this is a linear expression. In contrast, 4 is a constant and does not involve any variables, so it is not a linear expression.

How do you tell if a triangle is similar or congruent?

Answers

When the sides and angles of two triangles match that triangle is congruent and When the angles of two triangles match that triangle is similar.

When the sides and angles of two triangles match, the triangles are said to be congruent. When the angles of two triangles match, the triangles are said to be similar. Thus, two triangles can be superimposed side to side and angle to angle.

Hence, when the sides and angles of two triangles match that triangle is congruent and When the angles of two triangles match that triangle is similar.

If two triangles have an equal number of comparable angles and sides, they are said to be similar. Similar figures are items that have two or more figures with the same shape but varying sizes.

how can we find out if a clustering method in unsupervised learning is a good one? group of answer choices the svm accuracy on data has the accuracy close to 100% the predicted labels are equal to actual labels the distances between different clusters are minimum the sum of distances between objects in the same cluster are minimum

Answers

What is Clustering method in unsupervised learning?

An method known as unsupervised learning discovers patterns in untagged data. The idea is to compel the computer to create a clear representation of its surroundings and then produce innovative material from it through imitation, which is a crucial learning method for people.

There are several ways to evaluate the performance of a clustering method in unsupervised learning. Some common evaluation metrics include:

The sum of distances between objects in the same cluster (also known as the intra-cluster distance): This measure indicates how closely the objects in each cluster are related to each other. A good clustering method will have a low intra-cluster distance, indicating that the objects within each cluster are similar to each other.The distances between different clusters (also known as the inter-cluster distance): This measure indicates how distinct the different clusters are from each other. A good clustering method will have a high inter-cluster distance, indicating that the clusters are well separated from each other.The predicted labels are equal to the actual labels: This measure is only applicable if you have labeled data and you are using the clustering method to classify the data into different categories. If the predicted labels are equal to the actual labels, it means that the clustering method is correctly identifying the different categories.The SVM accuracy on the data: This measure is only applicable if you are using a support vector machine (SVM) as a classifier after the clustering step. The SVM accuracy indicates how well the SVM is able to classify the data based on the clusters produced by the clustering method. A good clustering method will result in high SVM accuracy.

- Given the line 3x-4y+24=0, determine the value of a, and b if the points (8.3,a) and (b, -10.2) are on the line.

Answers

Answer:

To find a, you'll put the value 8.3 as x in the equation to get the value of y which is equal to a. For the second point you'll put -10.2 as the value of y in the equation to get x which is equivalent to b.

Step-by-step explanation:

every point represents an ordered pair of (x, y) values.

if the point is on the given line (or any other form of curve/ function), then these x and y values make the functional equation true. if the equation turns out to be false with these values, then the point is not on that functional curve.

so, we need to find a and b to make the equations true.

(8.3, a)

3×8.3 - 4a + 24 = 0

24.9 + 24 = 4a

48.9 = 4a

a = 48.9/4 = 12.225

(b, -10.2)

3b - 4×-10.2 + 24 = 0

3b + 40.8 + 24 = 0

3b + 64.8 = 0

3b = -64.8

b = -64.8/3 = -21.6

Notice that y is on a straight line?

Straight lines are 180-degree angles called straight angles.

Hence:

                                        the total sum of angles in a triangle is 180 degrees

180-y+x+70=x+y+70  ==> since both expressions equal 180, they both are

                                         equal to each other

180-y+x+70 + y = x+y+70 + y ==> add y on both sides to isolate y to one side

180 - y + y + x + 70 = x + y + y + 70  ==> simplify

180 + x + 70 = x + 2y + 70

180+x+70 - x = x+2y+70 - x  ==> subtract x on both sides to eliminate x

180 + x - x + 70 = x - x + 2y + 70  ==> simplify

180 + 70 = 2y + 70

180 + 70 - 70 = 2y + 70 - 70 ==> subtract both sides by 70 to simplify the equation

180 = 2y

y = 180/2

The probability that 5 people sit in the correct order in either direction clock or anti-clock is equal to the probability of any one of the orders occurring, which is 1/2, or 50%.

To calculate the probability that they sit in the correct order in both directions, you would multiply the probability of each event occurring. Since the probability of either event occurring is 1/2, the probability of both events occurring is (1/2) * (1/2) = 1/4, or 25%.

The maximum capacity of a theater is 471 people. So far, 254 people are seated in the theater. If p represents the number of people that can still enter the theater, write an inequality that represents the situation.

Answers

Answer: [tex]p + 254 \leq 471[/tex]

Step-by-step explanation:

The number of people in the theater plus 254 )the number of people already in the theater) must be less than or equal to the maximum amount allowed to be seated, 471.

So, [tex]p + 254[/tex] represents the number of people in the theater.

471 is the maximum amount of people.

So, p + 254 must be less than or equal to [tex]p + 254[/tex].

Therefore, we can say that:

[tex]p + 254 \leq 471[/tex]
