Which angle is formed by a secant and tangent line?O ANGO GSEO EGSO NGL
The angle is formed by a secant and tangent line is GSE.
NS is a secant, whereas SE is a tangent line. Thus, they combine to form the angle GSE.
Tangents to circles are lines that cross the circle at a single point. Point of tangency refers to the location where a tangent and a circle converge. The circle's radius, where the tangent crosses it, is perpendicular to the tangent. Any curved form can be considered a tangent. Tangent has an equation since it is a line. A line that touches a circle just once is said to be tangent to it. A point to circle can only have one tangent. The intersection of the tangent and the circle is known as the point of tangency.

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
1 roll = 3 feet of ribbon
So, 5 rolls = 5 x 3 = 15 feet of ribbon
and, 1 foot = 12 inches
Then, 15 feet = 15 x 12 = 180 inches
The dressmaker has 180 inches of ribbon in total.
Now, the 4-inch pieces can the dressmaker cut from 5 of these rolls of
ribbon
= 180 / 4

Examine the following sequence 1,4,9, 16, 25 Why is 36 the next number in the sequence? Because the pattern is:
a. Add the next even number
b. Square the number of the next term, n
c. Cube the number of the term, n
d. Add 2 + the number of the term, n
Answer:
b. Square the number of the next term, n
Step-by-step explanation:
You want to know the pattern of the sequence 1, 4, 9, 16, 25, ... and why it tells you the next number is 36.
PatternUsually we look for a common difference or a common ratio when we're trying to identify a sequence as arithmetic or exponential. This sequence has neither, as the differences are 3, 5, 7, 9, and the ratios are 4, 9/4, 25/16.
Neither of these are constant sequences. However, we do notice that the sequence of differences has a common difference of 2. The fact that "second differences" are common (all the same) means the sequence can be described by a second-degree polynomial.
Looking at the sequence values, we see they are ...
1 = 1², 4 = 2², 9 = 3², 16 = 4², 25 = 5²
so we expect the 6th term to be the square of 6, 6² = 36. This is in line with the predicted next number.
The pattern is ...
square the number of the next term, n
What is 4 Ounces (4oz) in Pounds (lb)?
4 ounces is equal to 0.25 pounds. Since 1 pound is equal to 16 ounces, to convert ounces to pounds, you need to divide the number of ounces by 16. So, 4 ounces divided by 16 equals 0.25 pounds.
One pound is equivalent to 16 ounces. To convert 4 ounces to pounds, you need to divide 4 by 16. This gives the result of 0.25 pounds, since 4 ounces is one-quarter of a pound. The conversion factor between ounces and pounds is useful when working with small weights, as ounces are commonly used to express small quantities of weight, while pounds are used for larger quantities. Knowing the conversion factor can help in many situations, such as when cooking, measuring ingredients or mailing a package, where it may be necessary to convert between different units of weight.

What is a factor of a polynomial?We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.
To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.
Given, A cubic polynomial f(x) = 2x³ - 11x² - 20x - 7.
Now, If f(7) = 0 then (x - 7) is a factor of the polynomial f(x).
Therefore, f(x) = (x - 7)(2x² + 3x + 1).
Now, 2x² + 3x + 1 = 0.
2x² + 2x + x + 1 = 0.
2x(x + 1) + 1(x + 1) = 0.
(x + 1)(2x + 1) = 0.

how to calculate hexagon sum of interior angles
Answer:
Step-by-step explanation:
The sum of the interior angles in a polygon can be calculated using the following formula:
(n - 2) * 180 degrees
where n is the number of sides in the polygon.
To understand why this formula works, let's consider a single interior angle in the polygon. Each interior angle is split into two equal angles that form a straight line. The sum of these two angles is 180 degrees. Now, if we look at all the interior angles in the polygon, we can see that they are divided into (n - 2) pairs of angles that form straight lines. This means that the sum of all the interior angles in the polygon is (n - 2) * 180 degrees.
For a hexagon, which has 6 sides, we can plug in n = 6:
(6 - 2) * 180 = 4 * 180 = 720 degrees
So, the sum of the interior angles in a hexagon is 720 degrees.

What is an angle ?An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.
Interior angles:- The inner angle made by the intersection of two polygonal sides.
Exterior angles:- The outer angle made by the intersection of two polygonal sides.
The evidence in the proof that supports the statement that m/AOW = 45° is:
Statement 3: ZZOB ZXOA. This means that ZOB and ZOA are vertical angles, which means they are congruent.
Statement 4: m/XOA = 45°. This is the measure of ZOA, which is congruent to ZOB.
Statement 7: m/XOA + m/AOW = m/XOW. This is the angle addition postulate, which states that the sum of the measures of the angles in a triangle is 180°.
So, combining these pieces of evidence, we have:
m/XOA = 45° and m/XOA + m/AOW = m/XOW,
therefore m/AOW = m/XOW - m/XOA
= 90° - 45°

The standard deviation of the given data is 8.
Option B is the correct answer.
What is the standard deviation?To calculate the standard deviation of the given data, we can use the following formula:
σ = √ [Σ(xi - μ)² / N
where σ is the standard deviation, xi is each data point, μ is the mean of the data, and N is the total number of data points.
We have,
The mean of the data:
μ = (24 + 28 + 32 + 36 + 40 + 44 + 48) / 7
= 36
Now,
We can calculate the sum of squared differences from the mean.
Σ(xi - μ)²
= (24 - 36)² + (28 - 36)² + (32 - 36)² + (36 - 36)² + (40 - 36)² + (44 - 36)²
+ (48 - 36)²
= 144 + 64 + 16 + 0 + 16 + 64 + 144
= 448
And,
We can substitute these values into the formula for the standard deviation.
So,
σ = √ [Σ(xi - μ)² / N]
= √[448 / 7]
= 8.13
= 8
Therefore,
The standard deviation of the given data is 8.

what is the morse fall scale
The Morse Fall Scale (MFS) is a standardized tool used to assess a patient's risk of falling. It is used by healthcare professionals in a variety of clinical settings, including hospitals, long-term care facilities, and home care.
The MFS was first developed in 1987 by Dr. Morse and her colleagues as a way to identify patients at high risk for falls and to implement fall prevention measures. The MFS is a quick and simple tool that assesses six different risk factors for falls. These risk factors include history of falling, secondary diagnosis, ambulatory aids, intravenous therapy, gait, and mental status. The MFS assigns points to each risk factor based on the severity of the risk, with a maximum score of 125. Patients who score higher on the MFS are considered to be at higher risk for falls and require more intensive fall prevention interventions. The MFS is useful for healthcare professionals in identifying patients at risk for falls and in developing an individualized fall prevention plan. The MFS is also useful in measuring the effectiveness of fall prevention interventions by allowing healthcare professionals to track a patient's progress over time. However, it is important to note that the MFS is only one tool in a comprehensive fall prevention program and should not be used in isolation.
In summary, the Morse Fall Scale is a standardized tool used to assess a patient's risk of falling. It is a simple and quick tool that assesses six different risk factors and assigns points based on the severity of the risk. The MFS is useful in identifying patients at risk for falls and in developing an individualized fall prevention plan.

Answer:
The drama club receives $9 for each ticket they sell.
Step-by-step explanation:
The total amount of money the drama club receives from selling 108 tickets is the difference between the total amount collected and the amount donated to the school.
Total amount collected = 108x + 972
Amount donated to the school = 108x
Amount received by the drama club = (108x + 972) - 108x = 972
Therefore, the drama club receives a fixed amount of $972 for selling 108 tickets.
To find how much money the drama club receives for each ticket sold, divide the total amount received by the number of tickets sold:
972/108 = $9
Therefore, the drama club receives $9 for each ticket they sell.

What are the 3 types of integers?
Answer: In summary, all integers can be classified as either positive, negative, or zero.
Step-by-step explanation:
There are three types of integers: positive integers, negative integers, and zero.
Positive integers: Positive integers are numbers greater than zero, such as 1, 2, 3, 4, and so on.
Negative integers: Negative integers are numbers less than zero, such as -1, -2, -3, -4, and so on.
Zero: Zero is an integer that is neither positive nor negative. It is the only integer that is neither positive nor negative, and it is often referred to as the "origin" on a number line.
In summary, all integers can be classified as either positive, negative, or zero.
Answer: The three types of integers are Zero (Neutral Integers), Negative Integers, and Positive Integers.
Step-by-step explanation:
Negative Integers are the ones that has a value less than zero, examples of these are -7, -8, -9.
Positive integers, on the other hand. Are the ones that has a value more than zero, examples of these are 10, 11, 12, 13.
Note: The key difference between Negative Integers and Positive Integers is that a negative integer has a "-" sign, while a positive integer does not.
Zero are the neutral integers which means that it's the integer that's in the middle of the positive and negative integers, it has neither a positive sign or a negative sign.
Another note: Integers do not include fractions or decimals, only whole numbers.
