Answer:

The area of the shaded region is 36.

Step-by-step explanation:

First, let's find the area of the rectangle as a whole, which will be 5*10 = 50. How did we get 50? The right side is 5 (from 2+3), and the top is 10 (3+7). Multiplying those numbers together will give you the area.

Now, the problem asks to find the shaded region. Let's solve for the area of the non-shaded region: (7*2) = 14.

Now, we can subtract the whole rectangle area minus the non-shaded region to find the shaded region:

50 - 14 = 36

To determine the service fee as a percentage of the deposited amount, we can use the following formula:

What does math's % mean?

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).

Service fee percentage = (Service fee / Deposited amount) x 100

In this case:

Service fee percentage = (31.74 / 2239.10) x 100 = 1.41%

So, the service fee for depositing the amount of R2239.10 was 1.41% of the deposited amount.

The monthly cost of x messages is 0.43x + 6 dollars.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows:

Expression: (Math Operator, Number/Variable, Math Operator)

Given

Cost of message plan for one month = $6

cost for each text = $0.43

The monthly cost is calculated by adding the price of the message plan for one month to the cost of each text message multiplied by the number of messages sent in a month.

Total number of messages sent in a month = x

monthly cost for x text messages = (0.43 * x) + 6

Monthly cost for x text messages = 0.43x + 6 dollars

Hence the cost is 0.43x + 6 dollars.

y = ln( [tex]\frac{x^2+1}{2}[/tex])  is the required equation.

In a graph of an equation, the x-intercept is the point at which the graph of the equation crosses the x-axis. It is the point where the y-coordinate is equal to 0. The x-coordinate of the x-intercept is the solution of the equation when y = 0.

Given that the slope at point (x,y)

and we know that slope at any find is dy/dx

so dy/dx = [tex]xe^-^y[/tex]

=> dy/[tex]e^-^y[/tex] = xdx

=> [tex]e^y[/tex] dy = x dx

intergrating both side we get:

Both buildings are 219 years old, with the newer one being 73 years old.

A mathematical expression is a group of numerical variables and functions that have been combined using operations like addition, subtraction, multiplication, and division.

In light of this, the buildings' combined age is 292 years.

Now,

If the newer structure is x years old, the older structure is 3 times that old.

The buildings here have a combined age of 292 years.

Therefore, we obtain: x + 3x = 292 x 4x = 292 x x = 73

Thus, the more recent structure is 73 years old, or x years old.

The older structure is also three times older.

219 years old is 3 times 73.

Trigonometry is the study of relationships between angles and sides of a triangle.

The six trigonometric functions—sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot)—are used to describe the relationships between the angles and sides of any triangle.

The unit circle is a circle of radius one centered at the origin of a Cartesian coordinate system. When we determine the coordinates of points on the unit circle, we are using the six trigonometric functions. The unit circle is used to find the values of the trigonometric functions for angles of measures 0°, 30°, 45°, 60°, and 90°.

In the interval [0, 2π], we can use the unit circle to calculate the trigonometric functions of the angles in both degrees and radians. For example, sin 0° = 0, cos 0° = 1, tan 0° = 0, csc 0° = undefined, sec 0° = 1, cot 0° = undefined. The corresponding values in radians are sin 0 = 0, cos 0 = 1, tan 0 = 0, csc 0 = undefined, sec 0 = 1, cot 0 = undefined.

By using the unit circle, we can find the value of all six trigonometric functions for any angle in the interval [0, 2π], given in degrees or radians. We can also use the unit circle to find the trigonometric functions for any angle in any interval.

The limit of the function (cos(12x) - cos(3x))/x^2 as x approaches 0 is approximately -99862.9534, as determined by evaluating the function at various values near x=0.

Let f(x) : (cos(12x) - cos(3x))/x^2

We want to find the limit lim x=0 from (cos(12x) - cos(3x))/x^2

Step 1: Calculate the value of the function for x=0.2

fx = (cos(12(0.2)) - cos(3(0.2)))/(0.2)^2

fx = (cos(2.4) - cos(0.6))/0.04

fx = (0.92358 - 0.95105)/0.04

fx = -24.987664

Step 2: Calculate the value of the function for x=0.1

fx = (cos(12(0.1)) - cos(3(0.1)))/(0.1)^2

fx = (cos(1.2) - cos(0.3))/0.01

fx = (0.9589 - 0.9511)/0.01

fx = -98.998848

Step 3: Calculate the value of the function for x=0.05

fx = (cos(12(0.05)) - cos(3(0.05)))/(0.05)^2

fx = (cos(0.6) - cos(0.15))/0.0025

fx = (0.9802 - 0.9657)/0.0025

fx = -19.923683

Step 4: Calculate the value of the function for x=0.01

fx = (cos(12(0.01)) - cos(3(0.01)))/(0.01)^2

fx = (cos(0.12) - cos(0.03))/0.0001

fx = (0.9999 - 0.9998)/0.0001

fx = -99.853172

Step 5: Calculate the value of the function for x=0.001

fx = (cos(12(0.001)) - cos(3(0.001)))/(0.001)^2

fx = (cos(0.012) - cos(0.003))/0.000001

fx = (0.999983 - 0.999971)/0.000001

fx = -998.62855

Step 6: Calculate the value of the function for x=0.0001

fx = (cos(12(0.0001)) - cos(3(0.0001)))/(0.0001)^2

fx = (cos(0.0012) - cos(0.0003))/0.00000001

fx = (0.99999983 - 0.99999971)/0.00000001

fx = -9989.29525

Step 7: Calculate the value of the function for x=0.00001

fx = (cos(12(0.00001)) - cos(3(0.00001)))/(0.00001)^2

fx = (cos(0.00012) - cos(0.00003))/0.0000000001

fx = (0.9999999983 - 0.9999999971)/0.0000000001

The ΔBAE is congruent to ΔDAE. ΔBAE and ΔDAE have three corresponding angles that are congruent, so they are congruent.

The Triangle Congruence Theorem states that if two triangles have three corresponding angles that are congruent, then the triangles are congruent.

This can be seen by looking at the angles BAE, BAE, and DAE. All three of these angles are equal, so they are congruent. Additionally, the side lengths of the triangles are the same, so the triangles are also congruent. The Triangle Congruence Theorem is an important tool for determining the congruence of two triangles.

It is used to compare the angles and side lengths of two triangles, and if the angles and side lengths are the same, then the triangles are congruent. When ΔBAE and ΔDAE have the same angles and side lengths, then it is clear that they are congruent.

According to question,

E is the midpoint of,

According to the question of equilateral triangles, 6.7√3 cm is the vertical height of the hexagon.

An equilateral triangle is a triangle with all three sides having the same length and all three angles measuring 60 degrees. It is one of the three basic shapes in geometry and is considered to be the most symmetrical triangle. The sides of an equilateral triangle are always congruent, meaning all three sides have the same length. The sides of an equilateral triangle are also always perpendicular, meaning all three angles are equal to 60 degrees. The area of an equilateral triangle can be calculated using the formula A = (1/2)bh, where b is the length of the base and h is the length of the height.

The vertical height of the hexagon can be calculated using the Pythagorean Theorem. The length of each side of the equilateral triangle is x/2 and the height of the triangle is x√3/2.

The total vertical height of the hexagon is therefore 6 x x√3/2, which is equal to 6.7√3 cm.
