H contains the identity element, is closed under multiplication, and is closed under taking inverses, H is a subgroup of G, as desired.

Let [tex]\mathcal{H}[/tex]  be a non-empty directed family of subgroups of a group G. We need to show that the union [tex]H=\bigcup_{H_i\in\mathcal{H}}H_i[/tex] is a subgroup of G.

First, note that H is non-empty since[tex]\mathcal{H}[/tex] is non-empty. We also have [tex]1_G \in H_i[/tex] for all [tex]H_i\in\mathcal{H}[/tex], so [tex]1_G \in H.[/tex]

Then there exist [tex]H_{i_1},H_{i_2}\in\mathcal{H}[/tex] such that [tex]h_1\in H_{i_1}[/tex] and [tex]h_2\in H_{i_2}.[/tex] Since [tex]\mathcal{H}[/tex] is directed, there exists[tex]H_{i_3}\in\mathcal{H}[/tex] such that [tex]H_{i_1}\cup H_{i_2} \subseteq H_{i_3}[/tex].

The total number of berry pitchers made is 15/5 or 3.

If the serving size of berry pitchers is 1/5, it means that each pitcher represents 1/5 of a full serving. To determine the total number of pitchers made, we need to calculate how many times 1/5 fits into the whole serving.

Let's assume that the total number of pitchers made is represented by "x". We can set up the following equation:

x * 1/5 = 3

To solve for "x," we multiply both sides of the equation by 5:

5 * (x * 1/5) = 5 * 3

This simplifies to:

x = 15/5

Thus, the total number of berry pitchers made is 15/5 or 3.

Step-by-step explanation:

The way you can think about volume is that we have some cross sectional area times the height of the solid.

27.

The volume of a square based pyramid is

[tex]v = {s}^{2} ( \frac{h}{3} )[/tex]

where h is the height of the pyramid

s is the side length of the square base.

S=7

h=12

[tex]v = {7}^{2} ( \frac{12}{3} ) = 49 \times 4 = 196[/tex]

28. The volume of a rectangular prism

[tex]v = l \times w \times h[/tex]

where l is length

w is width

h is height

[tex]v = 11 \times 11 \times 8 = 968[/tex]

29.

Use the same formula in 27

[tex]v = 100(3) = 300[/tex]

30.

Volume of a Cylinder is

[tex]v = \pi {r}^{2} h[/tex]

where r is the radius of the circle

where h is the height

r is half of the diameter

The diameter is 22, thus the radius is 11.

[tex]v = {11}^{2} (8)(\pi)[/tex]

[tex]v = 968\pi[/tex]

pi is approximately 3.14

[tex]v = 3041.06[/tex]

31. Volume of A Sphere

[tex] \frac{4}{3} \pi {r}^{3} = v[/tex]

The radius is half of diamter, thus r=7

[tex] \frac{4}{3} \pi( {7}^{3} ) = 1436.76[/tex]

The area of the regular polygon is 311.5 in2.

We are given that;

A polygon

Now,

To find the perimeter of the regular polygon, we need to multiply the number of sides by the length of each side. The polygon has 7 sides and each side is 10 in long, so the perimeter is 7 * 10 = 70 in.

To find the apothem length, we need to use some trigonometry.

The central angle is 360/7 degrees, since there are 7 equal angles in a regular polygon. Half of the side length is 5 in, since each side is 10 in long. The apothem is the adjacent side of the right triangle. We can use the tangent function to find the apothem: tan(360/14) = 5/a, where a is the apothem. Solving for a, we get a = 5/tan(360/14) ≈ 8.9 in.

To find the area of the regular polygon, we need to plug in the values of P and a into the formula A = (1/2)P*a.

A = (1/2)708.9 ≈ 311.5 in2.

Therefore, by the area the answer will be 311.5 in2.

I agree that Nicole made a mistake because the total cost of the Five year plan is $ 34, 000 and not $ 74, 000.

Answer:

Part A: The point z1 is at (4, 6) and the point z2 is at (-5, 2). The distance between them is √((4-(-5))^2 + (6-2)^2) = √(9^2 + 4^2) = √(81 + 16) = √97.

Part B: The complex conjugate of z2 is (-5, -2). Geometrically, it can be found by reflecting the point z2 across the x-axis.

Part C: To find z2 − z1 geometrically, you can draw a vector from z1 to z2. The coordinates of this vector are (-5-4, 2-6) = (-9, -4). So z2 − z1 = -9 - 4i.

The monthly payment added to your mortgage for property taxes is $270.25, rounded to the nearest cent. It is a good idea to budget for property taxes when purchasing a home, as they can be a significant expense that should not be overlooked.

To calculate the monthly payment added to your mortgage for property taxes, we can use the following steps:

1) Find the taxable value of the home by subtracting the exemption from the appraised value:

Taxable value = $315,000 - $50,000 = $265,000

2) Calculate the annual property tax by multiplying the taxable value by the tax rate:

Annual property tax = $265,000 x 0.0122 = $3,243

3) Divide the annual property tax by 12 to get the monthly payment:

Monthly property tax payment = $3,243 / 12 = $270.25

It's important to note that property tax rates can vary depending on where you live, so it's a good idea to check with your local tax authority to get an accurate estimate of your property tax bill.

The additional tax (liability) that Lynn owes after her employer withheld $3,150 from her pay is D. $399.

Tax liability refers to the amount that a taxpayer owes.

We can determine the tax liability as the difference between the total tax and the employer-withheld tax.

The total tax is computed by applying the rate to the taxable income, which is the difference between the total income and the total deductions.

Lynn's total income last year = $38,900

Total deductions = $11,450

Employer withheld taxes = $3,150

Taxable income = $27,450 ($38,900 - $11,450)

From the tax table, when taxable income is at least $27,450 but less than $27,500, the total tax is $3,549, based on being a head of household.

The tax liability = $399 ($3,549 - $3,150)

Thus, Lynn is expected to remit an additional $399 to settle her tax liability.

The option that is not equivalent to x ¹⁸ is D. x ¹⁹

As a means to simplify option 1, we can incorporate the rule of multiplying two powers with an identical base to add their exponents. For instance, by doing x³ × x¹⁵ , we would end up with x¹⁸, which ultimately leads to x ¹⁸ as an equivalent result.

By applying the understood concept that when raising a power to itself,exponents must be multiplied together, option 2 becomes more understandable. Specifically, (x ² ) ⁹ = x ¹⁸,the same equivalence as x¹⁸.

Similarly, option 3 assimilates this approach; (x ⁶ ) ³ = x¹⁸,leading to x¹⁸ once again as an equal resonance.

The rectangle with points (0, 0), (0, 1), (2, 0), and (2, 1) could be the result of dilating the given rectangle with a scale factor between 0 and 1.

Option B is the correct answer.

We have,

Dilation is a transformation that changes the size of an object.

When a figure is dilated with a scale factor between 0 and 1, the resulting figure is smaller than the original.

The scale factor indicates how much smaller the image is compared to the original.

For example, a scale factor of 0.5 would mean that the image is half the size of the original.

Now,

The rectangle with points (0, 0), (0, 1), (2, 0), and (2, 1) could be the result of dilating the given rectangle with a scale factor between 0 and 1.

This is because the side lengths of the second rectangle are half of the side lengths of the first rectangle, which means that the second rectangle is a dilation of the first rectangle with a scale factor of 0.5.
