The electric potential V at any point on the y-axis inside the triangle can be expressed in terms of the charge Q, the length of the triangle l, and the distance y from the origin. The expression is V(y) = (Q/2l)y - (Q/2l)(2l-y) = (Q/l)(y - l).

The electric potential V at any point on the y-axis inside the triangle can be expressed in terms of the charge Q, the length of the triangle l, and the distance y from the origin. To find the expression, first note that the total charge of the triangle is Q, and the electric potential at the origin is 0. The distance from the origin to the top corner of the triangle is 2l. The electric potential at the top corner of the triangle is then equal to the total charge of the triangle divided by the length of the triangle, or Q/2l. The electric potential at any point on the y-axis is then equal to the total charge of the triangle divided by the length of the triangle times the distance from the origin to the point, minus the total charge of the triangle divided by the length of the triangle times the distance from the top corner of the triangle to the point. This gives the expression V(y) = (Q/2l)y - (Q/2l)(2l-y) = (Q/l)(y - l).

Answer:28

Step-by-step explanation:

Trick: just check if it's divisible by both numbers

Order of the side lengths EF, FG, and GE from least to greatest is EF < FG < GE.

When the lengths of two sides and the size of the included angle are known (SAS) or when the lengths of all three sides are known (SSS), the Law of Cosines can be used to determine the remaining components of an oblique (non-right) triangle. We are unable to establish a solvable percentage in either of these scenarios, making it impossible to apply the Law of Sines.

According to the Law of Cosines:

c² = a² + b² - 2ab * cos(C)

With the exception of the third component, which equals zero if C is a straight angle and the Pythagorean Theorem results, this is similar to the Pythagorean Theorem. As a result, the Law of Cosines is a specific case of the Pythagorean Theorem.

Using the Law of Cosines

In the given triangle, we are given the measure of angle G and the length of side FG, so we can use the Law of Cosines to find the lengths of the other sides. The Law of Cosines states that for a triangle with sides a, b, and c and angle C opposite side c, the relationship between the sides and the angle is:

c² = a² + b² - 2ab * cos(C)

Given: angle G = 72°, FG = 6

We can use the Law of Cosines to find the lengths of the other sides:

EF² = FG² + GE² - 2FG * GE * cos(G)

EF = √(6² + GE² - 2 * 6 * GE * cos(72))

FG² = EF² + GE² - 2EF * GE * cos(F)

FG = √(EF² + GE² - 2 * EF * GE * cos(66))

As we don't have any value for GE, we can't calculate the exact values, but as we know that the side opposite to the largest angle is the longest side of a triangle, so we can order the sides as follows:

EF < FG < GE

It means that side GE is the longest side of the triangle, followed by side FG, and side EF is the shortest side of the triangle.

What is the area of a figure?

The area of a figure is a measure of the amount of space inside a two-dimensional shape. The area of a figure is typically represented by the symbol A, and is usually measured in square units, such as square inches or square centimeters.

In the given figure, there are four triangles.

Two of  them have the same area and other two have the same area

Area of one triangle = 1/2 * height * breadth

                                 = 1/2 * 4 * 6

                                 = 12

Area of other triangle = 1/2 * height * breadth

                                 = 1/2 * 4 * 4

                                 = 8

Area of figure = 2 * 12 + 2 * 8

                       = 24 + 16

                       = 40 square mm.

It is used to perform binary classification with a high level of accuracy.

Support Vector Machines (SVMs) is a powerful algorithm with the potential to perform best in a binary classification problem with a non-linear complex function. SVMs are based on the concept of maximizing the margin between two classes of data points in the feature space. This is done by solving the optimization problem, which is formulated as a quadratic programming problem.

The formulation of the optimization problem for an SVM model is given by:

minimize W,b

subject to

y_i(w^T x_i + b) ≥ 1,  i = 1,2,…,n

where W is the weight vector, b is the bias, x_i is the ith feature vector, and y_i is the ith class label.

The goal of the optimization problem is to find the weight vector W and bias b such that the distance between the two classes is maximized. This is done by minimizing the objective function, which is the sum  of the weight vector. By solving this optimization problem, we can obtain an optimal hyperplane that separates the two classes. SVMs are powerful algorithms capable of dealing with non-linear complex functions, and can thus be used to perform binary classification with a high level of accuracy.

where (h, k) is the center of the ellipse, a is the distance from the center to a vertex, and b is the distance from the center to the focus.

Given that the center of the ellipse is at (2, 1), one vertex is at (2, -4), and one focus is at (2, -2), we can use this information to find the values of a and b, and represent the equation of the ellipse:

a = distance from center to vertex = |1 - (-4)|/2 = 2.5

b = distance from center to focus = |1 - (-2)|/2 = 1.5

The equation of the ellipse is:

Triangles are polygons in geometry that have three sides and three vertices. This figure is two-dimensional and has three straight sides. A triangle is a three-sided polygon. A triangle's three angles added together equals 180°. A single plane contains the triangle. The triangle is classified into six forms based on its sides and angles.

A triangle is categorized into three categories based on its sides, namely:

Scalene Triangle - Each side has a distinct length.

Isosceles Triangle - A triangle with two sides of equal length and one side of a different length.

Equilateral Triangle - A triangle has three sides that are of the same length.

A triangle is categorized into three categories based on its angles, namely:

Acute Angle Triangle - A triangle with all of its angles smaller than 90°.

Obtuse Angle Triangle - A triangle with one of its angles larger than 90°.

Triangle with a Right Angle - A triangle with one of its angles equal to 90°.

Now,

As shown in image  that the angles ∠BAD and ∠ADC are alternate angles, and therefore equal. Likewise, angles ∠ABC and BCD are also alternate and therefore equal.

∠BEA and ∠CED are opposite, which means that they are equal. You can see these equal angles in the image.

This means that the triangles ABE and DCE have the same angles as each other, and are therefore similar.

This means:

AE/ED=AB/DC=5m/10m=1/2

Therefore AE=1/3AD
