A concave hexagon with 2 pairs of congruent sides is a shape that has six sides and two pairs of sides that are of equal length, but the shape curves inward at one or more angles, creating a concave indentation.

A hexagon is a six-sided polygon, and when two pairs of its sides are congruent,

it means that four of its sides have the same length, if the shape curves inward at one or more angles,

it creates a concave hexagon, which means that the indentation on the shape is facing inward, rather than outward, a concave hexagon with 2 pairs of congruent sides is a six-sided polygon with four sides of equal length, but with a curvature that creates an inward indentation.

Hence, a concave hexagon with 2 pairs of congruent sides is a six-sided figure with an indentation and two sets of sides with equal lengths.

Answer:

I think it is 4/9 pi r

Step-by-step explanation:

according to the condition given:

2nd cone has:

Height = 12cm

r= 1/3r (cause it's given 1/3 of radius of the original cone)

We know that volume of a cone is = 1/3 pi (r)^2 h

Now substitute the values:

1/3 * pi* (1/3r)^2 * 12

when u simplify u will get

pi* 1/9*r*4 = 4/9 pi r

So, the answer is probably 4/9 pi r.

Answer:

S = Ph + 2B

Step-by-step explanation:

Looking at the available options given:

a) P = SB + 2h

Option a has to do with the Perimeter of a prism

b) S = Ph + 2B

Option b is the surface area of a prism specifically it represents the surface area of a triangular prism.

c) B = Sh + 2P

This is used to find the Base area of a prism.

Therefore, Option b is the correct option.

Answer:

Step-by-step explanation:

Assuming KH is a straight line with K and H being the beginning and the end of the line. If J is between H and K, it means that J is a point on line HK. Therefore, we can say that

HJ + JK= KH

If HJ = 4x + 9, JK = 3x + 3 and KH = 33, it means that

4x + 9 + 3x + 3 = 33

4x + 3x = 33 - (9 + 3)

7x = 21

Dividing both sides of the equation by 7, it becomes

x = 21/7 = 3

Therefore, HJ = 4 × 3 + 9 = 21

To go from circle A to B, we apply a translation of <-5, -5> and a dilation of scale factor k = 2.

The equation for circle A is:

(x + 2)^2 + (y - 4)^2 = 4^2 =  16

The equation for circle B is:

(x - 3)^2 + (y - 9)^2 = 8^2 = 64

So, if we start with circle B, we need to apply a translation of <-5, -5> to go to the center of B, then if we apply a dilation of scale factor K, the radius of the circle becomes 4*k.

Particularly of k = 2, we get:

4*2 = 8

So the scale factor k = 2 transforms the radius from 4 to 8.

Finally, if we apply these two transformations to circle A, we get circle B, which means that the circles are similar.

Answer:

\(5\sqrt{5}\)

Step-by-step explanation:

1. \(5^2 +10 ^2 = c^2\)

2. \(c^2 = 125\)

3. \(c = 5\sqrt{5}\)

Answer:

approximately 11.18 inches or \(5\sqrt{5\) inches

Step-by-step explanation:

We have to use Pythagorean Theorem for this problem. a^2 + b^2 = c^2, where c is the hypotenuse and a/b are legs of the right triangle.

5^2 + 10^2 = c^2, 25 + 100 = c^2, 125 = c^2, sqrt125 = c

sqrt125 can be simplified to 5sqrt5 (25 * 5 = 125, sqrt25 = 5)

The hypotenuse is approximately 11.18 inches or \(5\sqrt{5\) inches.

Answer:

There are 9,294,695,280 different ways to choose the officiers.

Step-by-step explanation:

The first thing we need to count is all the "selections", then we need to find the number of options for each one of these selections.

The selections are:

president

vice-president

secretary

treasurer

So we have 4 selections, now let's find the number of options for each one.

President: Here we have 312 options (the number of students).

Vice-president: Here we have 311 options (because one of the students was selected to be president)

Secretary: Here we have 310 options (because 2 students where already selected for the two previous positions)

Treasurer: Here we have 309 options.

The total number of different ways to select the officers is equal to the product between the numbers of options, this is:

C = 312*311*310*309 = 9,294,695,280

There are 9,294,695,280 different ways to choose the officiers.

In the above case, the possible point system will be:

1st choice vote: 4 points

2nd choice vote: 2 points

In arranging for the turtle to win in this point framework, the point values relegated for 1st choice and 2nd choice votes have to be meet the taking after criteria:

Lets say:

1st choice vote: 4 points

2nd choice vote: 2 points

Thus by the use of these point values, the turtle would have the next chance of winning since 1st choice votes would be worth more point (4 point ) compared to 2nd choice votes (3 point ). This would push individuals to select the turtle as their 1st choice, because it would allow the turtle a better add up to point gains and increase its chances of winning.

Answer:

Step-by-step explanation:

x2=-1, which simplifies the rule for addition and multiplication of congruence product to [ac - bd] + [ad+bc]x

In the given field R[x]/(x2+1), the rules for addition and multiplication of congruence classes are given below:

Rules for addition:

The addition of two congruence classes in R[x]/(x2+1) is done by adding their respective coefficients and then finding the remainder when divided by x2+1.

That is, if the sum [ax+b]+[cx+d] = [rx+s], then r = a+c, and s = b+d.

The addition of two congruence classes is done as follows:

[a,b]+[c,d] = [a+c, b+d] (mod x2+1) = [a+c-(b+d)x, b+d]

Rules for multiplication:

The multiplication of two congruence classes in R[x]/(x2+1) is done by FOIL method, then reduce the polynomial by x2+1.

That is, if the product [ax+b][cx+d] = [ux+v],

then

u = ac + bd, v = ad + bc.

The multiplication of two congruence classes is done as follows:

[a,b] [c,d] = [(ac+bd), (ad+bc)] (mod x2+1) = [(ac+bd)-(ad+bc)x, (ad+bc)]

The given product is [ax+b][cx+d] = [acx2 + (ad+bc)x + bd] (mod x2+1).

But x2+1=0,

hence x2=-1, which simplifies the above product to [ac - bd] + [ad+bc]x.

Answer: The first answer choice

AKA: y = -1.74x + 46.6

Step-by-step explanation:

A function assigns the values. The profit-maximizing quantity of labour to hire is 15 workers.

A function assigns the value of each element of one set to the other specific element of another set.

Given the marginal revenue product, MRP = 40-(Q/10)

The cost of labour, WL = 10

The production function, Q = 20 L

For profit maximizing quantity of labour to hire where,

MRP = WL

40-(Q/10) = 10

40-(20L/10)=10

40-2L=10

-2L = 10-40

Adding parentheses to a regular expression can be used to capture specific information, such as the street number and apartment number in this example.

A regular expression is a pattern used to match and search for specific strings. To remember the street number "613" and apartment number "apt 57" but not the street name, we can add parentheses to the regular expression to create capturing groups. The parentheses will capture the desired information and allow us to reference it later if needed.

The regular expression would look something like this: (613) (apt 57)

The parentheses indicate that the information inside should be captured as a group. This regular expression will match a string that contains the street number "613" and the apartment number "apt 57", and capture these values in two separate groups.

For example, if we have the following address: "613 Main St, apt 57"

We can use the regular expression to match the desired information:

(613) (apt 57)

In this case, the two groups captured are "613" and "apt 57". The information inside the parentheses can be accessed and used for various purposes, such as formatting or validation.

In summary, adding parentheses to a regular expression can be used to capture specific information, such as the street number and apartment number in this example. This allows for more precise and flexible matching and extraction of information from strings.

Therefore, Adding parentheses to a regular expression can be used to capture specific information, such as the street number and apartment number in this example.
