Use pythagorean theorem to answer.

([G,G]\) is a group, which is the subgroup of \(G \times G\) generated by the set of all commutators \([g,h]\).

To fix \(G\) as a group and set \([g,h]:=g h g^{-1} h^{-1}\), and then set
\[[G,G] := \left\{\left[g_{1}, h_{1}\right] \cdots\left[g_{s}, h_{s}\right]: g_{1}, \ldots, g_{s}, h_{1}, \ldots, h_{s} \in G\right\}\), we can start by noticing that this is a subset of the Cartesian product of \(G\) with itself, and since \(G\) is a group, this subset must also be a group. Therefore, \([G,G]\) is a group, which is the subgroup of \(G \times G\) generated by the set of all commutators \([g,h]\).

The area οf the cοmpοsite shape is 541 square meters.

Cοmpοsite shapes refer tο 2D shapes that are made up οf twο οr mοre simple shapes. These simple shapes can be cοmbined tο fοrm a mοre cοmplex shape.

Tο find the area οf this cοmpοsite shape, we need tο divide it intο smaller shapes and add up their areas. Let's divide it intο twο rectangles and a triangle:

First rectangle:

Length = 18 m

Width = 11 m

Area = length x width = 18 m x 11 m = 198 m²

Secοnd rectangle

Length = 14 m

Width = 20 m

Area = length x width = 14 m x 20 m = 280 m²

Triangle:

Base = 14 m

Height = 9 m (we can find this by subtracting the height οf the tοp rectangle frοm the height οf the entire shape: 20 m - 11 m = 9 m)

Area = (base x height) / 2 = (14 m x 9 m) / 2 = 63 m²

Nοw we add up the areas οf the three shapes tο get the tοtal area οf the cοmpοsite shape:

Tοtal area = 198 m² + 280 m² + 63 m² = 541 m²

Hence, the area οf the cοmpοsite shape is 541 square meters.

The solutions to the equation z^2 = -361 are:

z = ±19i and z = ±19i*(-1)^k, k = 0 or 1.

To find all n complex solutions of the equation x^n = k, where k is a complex number, we can use the polar form of complex numbers. If we write k in polar form as k = re^(iθ), where r = |k| is the modulus of k and θ = arg(k) is the argument of k, then we can write x in polar form as x = ρe^(iφ), where ρ = |x| is the modulus of x and φ = arg(x) is the argument of x.

Substituting these polar forms into the equation x^n = k, we get:

(ρe^(iφ))^n = re^(iθ)

Taking the modulus of both sides, we get:

|ρ^n| = |r|

Since r is a complex number, its modulus is a positive real number, so we can write r = Re^(i0) in polar form, where R = |r|.

Substituting this into the equation above, we get:

|ρ^n| = R

Taking the argument of both sides, we get:

nφ = 0 + 2πk

where k is an integer. Solving for φ, we get:

φ = (2π*k) / n

Substituting this expression for φ back into the polar form of x, we get:

x = ρe^(i(2π*k)/n)

where ρ is a positive real number. This gives us n complex solutions for x, which are:

x = ρe^(i(2π*k)/n), k = 0, 1, 2, ..., n-1.

Now let's apply this method to solve the equation z^2 = -361.

Writing -361 in polar form, we have:

-361 = 361e^(iπ)

Taking the square root of both sides, we get:

z = ±sqrt(361)e^(iπ/2 + iπk)

where k = 0 or 1. Simplifying, we get:

z = ±19e^(i(π/2 + π*k))

So the solutions to the equation z^2 = -361 are:

z = ±19i and z = ±19i*(-1)^k, k = 0 or 1.

The probability of at most one price hike in one year is 0 + 0 = 0.

No price hikes in a randomly selected one and a half year:

The probability of no price hikes in one year is 0, since the average is 4. Therefore, the probability of no price hikes in one and a half years is also 0.

Four price hikes in 2 years:

The average number of price hikes in one year is 4, so the average number of price hikes in 2 years is 8. The probability of exactly 4 price hikes in 2 years is therefore 0, since it is less than the average.

At most one price hike in one year:

The probability of at most one price hike in one year is the sum of the probabilities of 0 and 1 price hikes. The probability of 0 price hikes is 0, as mentioned before. The probability of 1 price hike is also 0, since it is less than the average of 4. Therefore, the probability of at most one price hike in one year is 0 + 0 = 0.

The following solutions with regard to resolving or simplifying the radii of the circular pond are given below.

Part A: 5√100 + √164 meters = 5 × 10 + 2√41 meters

Part B: 5 × 10 + 2√41 meters = 50 + 2√41 meters

Part C: The radius of Pond B is 10√2 meters.

Part D: the radius of Pond B is greater than the radius of Pond A.

Part A: The mistake is in Step 1. To simplify the square root of 164, we need to find its prime factors:

164 = 2 × 2 × 41

So, we can write:

√164 = √(2 × 2 × 41) = 2√41

Using this, we can rewrite Step 1 as:

5√100 + √164 meters = 5 × 10 + 2√41 meters

Part B: Using the corrected step from Part A, we can simplify the radius of Pond A as:

5 × 10 + 2√41 meters = 50 + 2√41 meters

So, the radius of Pond A is 50 + 2√41 meters.

Part C: The radius of Pond B is already simplified, so we don't need to do any additional steps. It is:

25√200/5 meters = 5√200 meters

We can simplify this further by finding the prime factorization of 200:

200 = 2 × 2 × 2 × 5 × 5

So, we can write:

√200 = √(2 × 2 × 2 × 5 × 5)

= 2 × 5√2

Using this, we can rewrite the expression for the radius of Pond B as:

5 × 2 × √2 meters

= 10√2 meters

Thus, the radius of Pond B is 10√2 meters.

Part D: We can compare the radii of the ponds using the original expressions by writing:

√164 < 25√200/5

Simplifying both sides:

2√41 < 10√2

Dividing both sides by 2:

√41 < 5√2

Squaring both sides (since both sides are positive):

41 < 25 × 2

41 < 50

So, the inequality is true. Therefore, the radius of Pond B is greater than the radius of Pond A.

The measures of the angles in the triangle are A = 6.17°,B = 11.50°, C = 162.33° and that's the solution to the triangle using the Law of Sines.

To solve the triangle using the Law of Sines, we can use the following formula:

(a/sin A) = (b/sin B) = (c/sin C)

First, let's convert the given angle B from degrees and minutes to decimal form:

B = 11° 30' = 11.5°

Next, we can plug in the given values into the formula and solve for the unknowns:

(3.7/sin A) = (6.5/sin 11.5°)

Cross-multiplying and rearranging gives us:

sin A = (3.7 * sin 11.5°) / 6.5

Using a calculator, we can find the value of sin A:

sin A = 0.1076

Now, we can use the inverse sine function to find the measure of angle A:

A = sin^-1(0.1076) = 6.17°

Finally, we can use the fact that the sum of the angles in a triangle is 180° to find the measure of angle C:

C = 180° - A - B = 180° - 6.17° - 11.5° = 162.33°

So, the measures of the angles in the triangle are:

A = 6.17°
B = 11.5°
C = 162.33°

Round your answers to two decimal places, we have:

A = 6.17°
B = 11.50°
C = 162.33°

And that's the solution to the triangle using the Law of Sines.

The radius of the circle is approximately 5.861 cm, and the area of the circle is approximately 107.76 cm².

A regular polygon is one that has an equal number of sides and angles. Each vertex of a regular polygon is located on a shared circle known as the circumscribed circle or circumcircle. A circumscribed circle or circumcircle of the polygon, on the other hand, is any circle that goes through every vertex of the polygon. The circumradius of the polygon is the circumference of the circle. The circumradius is the distance from the centre to any vertex of a regular polygon with n sides, and the circumcircle's centre coincides with the polygon's centre.

Given that, the hexagon is regular, angle AOB is 60 degrees.

The side AB is given as 8cm.

Using trigonometric functions we have:

h = r * cos(30 degrees) = (√(3)/2) * r.

Now using the Pythagoras theorem:

OB² = AB² - h².

Substituting the value of h:

OB² = 8² - (√(3)/2)² * r².

OB² = 64 - (3/4) * r².

OB = √(64 - (3/4) * r²).

Here, OB is equal to the radius of the circle.

r = √(64 - (3/4) * r²) = 5.861 cm.
