Answer : Undefined terms are those terms that don’t require a formal definition. The four terms are point line plane and set

Step-by-step explanation:

If x is near but not equal​ to, the value an is that f(a) then the function will not continue.

Limit, a nearness in mathematical notion, is largely used to give values to some functions at locations that were usually not given or defined, in a manner consistent with neighboring values.

In another word, limit is a mathematical concept in which we find out the value of any function at a point by its adjacent very close point.

If a function f(x) is defined near to x = a but not a then there will be no continuity of that function at that point.

To exist a limit at x = a

LHL = RHL

But for continuity

LHL = RHL = f(a)

Hence "If x is near but not equal​ to, the value an is that f(a) then the function will not continue".

Answer: 12w-9

Step-by-step explanation:

Segment PS in the scaled copy corresponds to segment AD in polygon ABCD in polygon PQRS. They are similar in appearance and appear in the same location.

A polygon is a two-dimensional flat shape with straight, fully closed sides. Straight, not curved, sides are required. Polygons, on the other hand, can have any number of sides.

Polygon is derived from the Greek word "polugonos." It has evolved into the term "polygon" over time. The term "polygon" means "many" and "gon" means "angled." This is due to the fact that a polygon has numerous angles and corners within its shape.

The Greeks may have been the first to recognize polygons, as there are numerous examples of them recognizing polygons such as the pentagram in their ancient art and writings.

The value of p is 2 and q is either 7 or 13 and their sum is either 9 or 15.

It is given that the value of p and q is a prime number, and p<q.

But it is also given that the value of both should be less than 18 as well as a prime number.

Therefore the value of both should be 2, 3, 5, 7, 11, 13, and 17.

And it is also given that p<q.

Now we have to find the value of p + q which is odd but not a prime number.

To have a sum as an odd number one number should be even and as it is given that p<q, therefore p=2, and q = 3, 5, 7, 11, 13, 17.

So

p + q = 2 + 5 = 7, which is odd but it is prime

Now again, q = 7

p + q = 2 + 7 = 9 , which is odd as well as not prime.

Again take q = 11

p + q = 2 + 11 = 13, which is odd but prime

Now take q = 13

p + q =  2 + 13 = 15, which is odd as well as not prime.

Now take q = 17

p + q = 2 + 17 = 19, which is odd and prime.

Therefore we have p =2 and q = 7 or 13 and sum p + q =9 or 15 which is odd but not prime.

The inequality for the number of cups of lemonade she can buy is :

Marilyn has $40 to spend in the amusement park.

Admission price = $20

So money left = 40 - 20 = $20

Now she plans to buy a sandwich for $5.

So the money left now will be = 20 - 5 = $15

Price of a cup of lemonade = $3

Marilyn can buy at most $15/3 = 5 cups of lemonade.

She can either choose to not buy a cup of lemonade or can buy at most 5 cups of lemonade.

researchers are interested in finding out if winning congressional candidates display more positive facial expressions than losing candidates. c. naturalistic observation

A study technique called naturalistic observation includes watching participants in their natural settings. Many psychologists and other social scientists employ this strategy. It is an approach to qualitative research that emphasizes gathering, analyzing, and describing non-numerical data.

When performing lab research would be impractical, expensive, or would adversely influence the subject's behavior, it may be helpful. Naturalistic observation is to capture behavior as it happens in its natural environment without intervention or efforts to change any of the factors. In a lab context, people frequently act differently than they would in the wild. Sometimes, researchers wish to watch their subject's behavior "in the wild".

IMS (Infinitely Many Solutions)

Step-by-step explanation:

1. Combine like terms (2/3x + 1/3x) Equation: 1x = x

2. 1x is just x, so the final equation is x = x. When you get an answer like this, it means there are infinitely many solutions.

The measure of x, that is, the angle OBA is equal to 22.5°.

Herein we find a geometric system formed by a circle, a diameter and a chord. In the image attached below we present all the possible angles of the geometric system, formed by two isosceles triangles.

According to Euclidean geometry, an isosceles triangle has two sides and two angles of equal length. Then, the sum of the internal angles of the triangle AOB is equal to:

m ∠ AOB + m ∠ OBA + m ∠ OAB = 180°

135° + 2 · m ∠ OBA = 180°

2 · m ∠ OBA = 45°

m ∠ OBA = 22.5°

By taking advantage of the properties of isosceles triangles, the measure of x, that is, the angle OBA is equal to 22.5°.

The result for the stack of cups are shown below;

The term unitary refers to a single or unique unit. As a result, the goal of this method is to determine values are related to a single unit.

Now, as per the given question.

Part 1: The height of one cup;

The stack of 9 cups form the height 194 mm.

Similarly, the height of the 22 of the same cups measures 272 mm.

For the calculation of height of one cup;

Difference in the total height  = 272 - 194 = 78.

Difference in the number of cups = 22 - 9 = 13.

Thus, the height of one cup = 78/13 = 6

The height of the one cup is found to be 6 mm.

Part 2: The height of n stack of cups;

The height of one cup is estimated as 6 mm.

There are total n number of cups.

The surface area of a cylinder with a height of 8 inches and base diameter of 6 inches is 207.24 square inches

The given parameters are

Height, h = 8 inches

Diameter, d = 6 inches

The radius is calculated as

r = d/2

So, we have

r = 6/2

r = 3

The surface area of a cylinder is calculated as

S = 2πr(r + h)

So, we have

S = 2 * 3.14 * 3 * (3 + 8)
