The area of the figure would be 40 square mm.

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.

Hence, the area of the figure would be 40 square mm.

The surface area of a rectangular prism is calculated by adding up the area of all its faces. To calculate the surface area of a rectangular prism, you can use the formula: 2(lw + lh + wh) where l represents the length, w represents the width and h represents the height.

In this case, the rectangular prism measures 7" x 7" x 4", so the surface area can be calculated as: 2(7" x 7" + 7" x 4" + 4" x 7") = 2(49" + 28" + 28") = 2(105") = 210 square inches.

It is important to note that the surface area is a measure of the total area of all the faces of a three-dimensional object, and it is always a positive value. Also, it is measured in squared units, in this case square inches, since all the measurements provided are in inches.

I hope this helps :)

Answer:

210 square

Step-by-step explanation:

just because

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.

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).

The vector field f is defined as f(x, y, z) = (-2, -2, -2).

This means that at any point (x, y, z), the vector is (-2, -2, -2). For example, if the point is (1, 2, 3) then the vector is (-2, -2, -2). This can be represented mathematically as f(1, 2, 3) = (-2, -2, -2). At the point (-2, -2, -2), the vector field is (-6, -6, -6). This can be calculated by substituting the given point into the formula. The x-coordinate of the vector is x+y+z = -2+(-2)+(-2) = -6. Similarly, the y-coordinate of the vector is x-y-2z = -2+(-2)-2(-2) = -6, and the z-coordinate of the vector is -2x+y+z = -2(-2)+(-2)+(-2) = -6.The vector field f is constant in all directions, meaning that the same vector is found at any point (x, y, z).

The value of k that makes the line 7x + ky = 35 parallel to the line 5x - 3y + 44 = 0 is k = -21/5. 

Two lines are parallel only if their slopes are the same. The slope of a line of the form y = mx + b (where m is the slope and b is the y-intercept) is m. The slope of a straight line of the form ax + by + c = 0 can be found using the formula: The calculation formula for the slope cutting shape will change.

So to find the value of k that makes the line 7x + ky = 35 parallel to the line 5x - 3y + 44 = 0, we need to find the slope of the line 5x - 3y + 44 = 0. To do this, we rearrange the equation into slope-intercept form.

5x - 3y + 44 = 0

-3y = -5x + 44

y = (5/3)x - 14.67

The straight line 5x - 3y + 44 = 0 has a slope of 5/3. In order for the 7x + ky = 35 line to be parallel to this line, the slope of 7x + ky = 35 must also be 5/3. To find the slope of 7x + ky = 35, rearrange the formula into slope-intercept form.

7x+ky=35

y = -(7/k)x + 35/k

Setting the slope of the line 7x + ky = 35 equal to the slope of the line 5x - 3y + 44 = 0 gives:

-(7/k) = 5/3

-7/k = 5/3

-7 * 3 = 5 * k

-21 = 5k

k = -21/5

Therefore, the value of k that makes the line 7x + ky = 35 parallel to the line 5x - 3y + 44 = 0 is k = -21/5.

The equation of a polynomial having x intercepts a₁,a₂,…,aₙ is [tex]P(x)=a(x-a_1)^{P_1}(x-a_2)^{P_2}....(x-a_n)^{P_n}[/tex].

Where P₁,P₂,…,Pₙ are the powers of the factors of the polynomial, which depend upon the behavior of the graph of the polynomial.

At this point x=-1, x=-4 and x=1 the graph passes through the axis linearly, therefore, the corresponding factor of the polynomial must be linear.

At x=2, the behavior of the polynomial is bouncing in nature, suggesting the corresponding factor of the polynomial having a second degree.

Now, the equation of the polynomial can be written as shown below:

P(x)=a(x+1)(x+4)(x-1)(x-2)²

The polynomial passes through the point (0, 2), therefore

2=a(0+1)(0+4)(0-1)(0-2)²

The relationship between x and y as a logarithmic equation is: y = log_36 9 = 2.

The relationship between x and y can be expressed as a logarithmic equation. Let's take a look at the two equations:

Equation 1: log36

To calculate the relationship between x and y, we will use the logarithmic property: logb(x) = y ⇔ b^y = x

From equation 1, we can solve for y:

log36 = y

⇒ 36^y = 36

⇒ y = 1

Therefore, the relationship between x and y is: x = 36^1 = 36.

To verify this, we can plug x = 36 into equation 2 and see if it is true:

Equation 2: y = log_x 9

Plugging in x = 36, we have:

y = log_36 9

⇒ y = log_36 3^2

⇒ y = 2

Therefore, the relationship between x and y is: y = log_36 9 = 2.

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.
