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

use method of reduction of order to find a second solution of the given equation; t^(2)y''+2ty'-2y=0, t>0
if y_1(t)=t , (given hint): set y_2= v(t)t
The second solution of the given differential equation t^2y''+2ty'-2y=0, t>0 is y_2(t) = c/t where c is an arbitrary constant.
The second solution of the given differential equation t^2y''+2ty'-2y=0, t>0 is y_2(t) = c/t where c is an arbitrary constant.
y_2(t) = t^2v'(t) + 2t v(t) - y_1(t)
Substituting y_1(t) and y_2(t) in the given equation, we get
t^2v''(t) + 2tv'(t) - 2v(t) = 0
This is a first order linear differential equation and can be solved as
v'(t) = -2v(t)/t
Integrating both sides, we get
v(t) = c/t^2
Therefore, the second solution of the given equation is
y_2(t) = c/t
The second solution of the given differential equation t^2y''+2ty'-2y=0, t>0 is y_2(t) = c/t where c is an arbitrary constant.

Kory pays 1/3 of his income in tax. He then spend 4/5 of what remains after tax, and places the rest into a savings account. What fraction of his income does he put into his saving account?
Answer:
2/5 of income put into savings
Step-by-step explanation:
Let Kory's income be X
1/3 of his income goes to taxes so taxes are X/3
Remaining is (1- 2/3) of income = (2/3 ) X
He spends 4/5 of this remaining amount
So balance after expenditure = (1- 4/5) = 1/5 of the remaining income and this amount is put into savings
Fraction of income in savings = 1/5 x 2/3 X = (2/15)X
So fraction put into savings account is 1/5 of total income
If you find it confusing to work with fractions such as these, I suggest an alternate approach which may make it easier to understand
Pick an amount for total income. Since the denominators are 3 and 5, choose an amount which is divisible by both 3 and 5 or in other words divisible by 15
Let's choose 300, a convenient number
Tax Paid = 1/3 x 300 = 100
Income after tax = 300 - 100 = 200
which is same as 2/3 x 300
Spending = 4/5 x 200 = 160
Balance in savings = 200 - 160 = 40 same as 1/5 x 200
So amount in savings as a fraction of income = 40/300 = 2/15

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,
AC⊥ BD,
As given E is the midpoint of the line ,
So, BE = ED,

the questions for quiz 2 will include all 6 trig functions with angles on the unit circle in the interval [0, 2pi], given in radians or degrees.
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.

What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
To solve the inequality |x + 1| > -3, we need to consider two cases:
x + 1 > -3: In this case, we can subtract 1 from both sides to get x > -4.
x + 1 < -3: In this case, we can subtract 1 from both sides to get x < -4. However, we also need to reverse the inequality symbol because we are multiplying or dividing by a negative number.
So the solution for the inequality is x > -4 or x < -4.

The 3-4-5 right triangle is a commonly used right triangle. Use the inverse sine function to determine the measure of the angle opposite the side of length 3.
The measure of the angle opposite the side of length 3 is approximately 53.13 degrees.
To find the measure of the angle opposite the side of length 3, we need to use the inverse sine function. The inverse sine function can be written as sin^−1(x). We can use the Pythagorean Theorem to calculate the side length of the triangle, which is 3^2 + 4^2 = 5^2. Therefore, we can use the inverse sine function to calculate the measure of the angle opposite the side of length 3. To do this, we will take the ratio of the side of length 3 to the hypotenuse, which is 3/5. We can then plug this value into the inverse sine function, which gives us sin^−1(3/5). Calculating this value gives us approximately 53.13 degrees, which is the measure of the angle opposite the side of length 3.

On 21/04 the service fee for depositing the amount of R2239.10 was 31.74. Determine the service fee as a percentage of the deposited amount
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.
