First, you'd work out the centre value

It would be the opposite value to what is in the brackets

Thus, the centre value is (2, -4)

Plot this value on a graph

In order to find the radius, you must square root the 25

Thus, the radius would be 5

Plot some points with a radius of 5 from the centre and then draw the circle

Add them together, and you get your answer.

the measure of the angle within the 10 degrees rotation is determined as 170 degrees.

The measure of the angle within the 10 degrees rotation is calculated by applying sum of circle theorem as shown  below.

The sum of angles in the straight line 180 degrees, and we can apply this principle in calculating the expected angle within the 10 degrees rotation as follows;

Let the expected measure of the angle = θ

θ + 10 = 180 ( sum of angles in a straight line )

θ = 180 - 10

θ = 170

Thus, the measure of the angle within the 10 degrees rotation is determined as 170 degrees.

Answer:

Step-by-step explanation:

Is the second exponent 6, or 6x ?

If it is 6x, then x = -½

The measure of angle ACB is half the difference between 180 degrees and the measure of arc AB.

The measure of angle ACB can be determined using the properties of tangents and secants intersecting a circle.

Since side AC is tangent to the circle, angle BAC is a right angle (90 degrees).

According to the tangent-secant theorem, the measure of angle ACB is equal to half the difference between the intercepted arcs AB and AX.

Since angle BAC is a right angle, the intercepted arc AX is a semicircle, which means its measure is 180 degrees. The intercepted arc AB is an arc of the circle and is less than 180 degrees since it is not a full circle.

Therefore, the measure of angle ACB is half the difference between 180 degrees and the measure of arc AB.

To find the exact measure, more information is needed about the length of arc AB or the relationship between the lengths of the sides of the triangle. Without this additional information, we cannot determine the precise measure of angle ACB.

The rate of change is 7 more of function A than the slope of function B.

Slope is calculated as the ratio of "vertical change" to "horizontal change" between any two points on a line, or any two points. When the ratio is expressed as a quotient ("rise over run"), the same number is provided for every two distinct locations on the same line. There is a negative "rise" on a descending line.

Since y=8x+3,

The rate of change in equation A is equal to the slope m m=8.

The rate of change, m=1, is given in equation B.

y=mx+ is the solution to equation B.

By substituting the values we get,

Answer:

a) 25

b) 30

c) 10

d) Not Mozart, 6

e) 2

Step-by-step explanation:

We use a Venn Diagram to solve this question.

I am going to say that:

A are the students who like Mozart.

B are the students who like Beethoven

C are the students who like Haydn.

We have that:

\(A = a + (A \cap B) + (A \cap C) + (A \cap B \cap C)\)

In which a are those who only like Mozart, \((A \cap B)\) are those who like Mozart and Beethoven, \((A \cap C)\) are those who like Mozart and Haydn and \((A \cap B \cap C)\) are those who like all three of them.

By the same logic, we have that:

\(B = b + (A \cap B) + (B \cap C) + (A \cap B \cap C)\)

\(C = c + (B \cap C) + (A \cap C) + (A \cap B \cap C)\)

We start finding these values from the intersection:

8 like all three composers

This means that \(A \cap B \cap C = 8\)

14 like Beethoven and Haydn

This means that:

\((B \cap C) + (A \cap B \cap C) = 14\)

So

\(B \cap C = 6\)

21 like Mozart and Haydn

This means that:

\((A \cap C) + (A \cap B \cap C) = 21\)

Then

\(A \cap C = 13\)

14 like Mozart and Beethoven

This means that:

\((A \cap B) + (A \cap B \cap C) = 14\)

\(A \cap B = 6\)

31 like Franz Joseph Haydn

This means that C = 31. So

\(C = c + (B \cap C) + (A \cap C) + (A \cap B \cap C)\)

\(31 = c + 6 + 13 + 8\)

\(c = 4\)

36 like Ludwig van Beethoven

This means that \(B = 36\)

So

\(B = b + (A \cap B) + (B \cap C) + (A \cap B \cap C)\)

\(36 = b + 6 + 6 + 8\)

\(b = 16\)

37 like Wolfgang Amadeus Mozart

This means that A = 37. Then

\(A = a + (A \cap B) + (A \cap C) + (A \cap B \cap C)\)

\(37 = a + 6 + 13 + 8\)

\(a = 10\)

a. exactly two of these composers?

\((A \cap B) + (A \cap C) + (B \cap C) = 6 + 13 + 6 = 25\)

b. exactly one of these composers?

\(a + b + c = 10 + 16 + 4 = 30\)

c. like only Mozart?

\(a = 10\)

d. like Beethoven and Haydn, but not Beethoven?

I will use not Mozart.

So \(B \cap C = 6\)

Not Mozart, 6.

e. like none of these composers?

At least 1:

\((A \cup B \cup C) = a + b + c + (A \cap B) + (A \cap C) + (B \cap C) + (A \cap B \cap C) = 10 + 16 + 4 + 6 + 13 + 6 + 8 = 63\)

The total is 65

So 65 - 63 = 2 like none of these composers

Object dilation for image 1 is 30 cm, image 2 is 21 cm, image 3 is 8 cm, and image 4 is 2 cm.

Dilation is a conversion, which is utilized to resize the thing. Dilation is operated to create things bigger or shorter.

For image 1, Dilation for the given side of polygon A is 10 × 3 = 30cm for polygon B.

Therefore, the dilation for the unknown side of polygon B would be 15 × 3 = 45cm.

For image 2, The dilation for the given side of triangle A is 7 × 3 = 21cm for triangle B.

Therefore, the dilation for the unknown side of triangle B would be 18 ÷ 3 = 6cm for triangle A.

For image 3, Dilation for the given side of triangle A is 12 × 4 = 48cm.

Therefore, the dilation for the unknown sides would be 32 ÷ 4 = 8cm for the left side of triangle A and 8 × 4 = 24 for the right side of triangle B.

For image 4, The dilation for the given side of square A is 2 × 2 = 4cm in square B.

Therefore, the dilation for the unknown side of square A would be 4 ÷ 2 = 2cm for square A.

Answer as an exact fraction = 5/18

Answer as an approximate decimal = 0.2778

Answer as an approximate percentage = 27.78%

============================================================

Explanation:

x = result of the first die

y = result of the second die

(x,y) paired together shows the results of both dice at the same time.

Something like (x,y) = (4,2) means we got 4 on the first die and 2 on the second die.

--------

Let's list the ways of rolling a 6

There are 5 ways to roll a 6. Each pair listed has the property x+y = 6.

--------

List all the ways of getting doubles

There are 6 ways to roll doubles. Each pair mentioned has x = y.

--------

We have 5+6 = 11 items listed above. However, there are only 10 unique pairs though because (3,3) was listed twice. So we could say 5+6-1 = 11-1 = 10.

This is out of 6*6 = 36 different ways to roll the two dice. The probability is therefore 10/36 = 5/18.

Using a calculator, 5/18 = 0.2778 = 27.78%

The sequence is geometric, with a common ratio of 1/3, and the missing terms are 12 and 4.

To determine if the sequence is arithmetic, geometric, or neither, let's examine the given terms: 972, 324, 108, 36.

To find the missing terms of the sequence, let's look for a pattern in the numbers:

If we divide each term by 3, we get:

972/3 = 324

324/3 = 108

108/3 = 36

It seems that each term is obtained by dividing the previous term by 3.

Now, let's check if the sequence is arithmetic or geometric:

If we calculate the common difference between consecutive terms, we see that there is no constant difference. For example:

324 - 972 = -648

108 - 324 = -216

36 - 108 = -72

Since the differences are not constant, the sequence is not arithmetic.

If we calculate the common ratio between consecutive terms by dividing a term by its previous term, we find that the ratio is constant:

324/972 = 1/3

108/324 = 1/3

36/108 = 1/3

The common ratio is 1/3, which indicates that the sequence is geometric.

The missing terms in the sequence are:

(36/3) = 12

(12/3) = 4

The complete sequence is: 972, 324, 108, 36, 12, 4.

The sequence is geometric, with a common ratio of 1/3, and the missing terms are 12 and 4.

We have an event where it is a spiner with 5 equal sides numbered from 1 to 5., since it is indicated that they are equal, we know that they all have the same conditions in everything that is, they have the same probabilities to come out.

i.e. the odds of each section coming out are about:

Since we are asked for the probability of a 1 or a 4 the probabilities of both events are added together:

With respect to experimental probability and theoretical probability, these are two aspects of probability, differentiated by the method of calculating the probability of an event. In experimental probability, the success and failure of the event in question are measured in a selected sample and then the probability is calculated. In theoretical probability, a mathematical model is used to determine the behavioral responses to an event within the considered sample or population.

Assuming this is a one time event, this is a theoretical probability, since we are basing this on the mathematical model developed in probability theory.

Keith's subsidized monthly payment upon graduation would be approximately $135.65.

Keith took out a student loan for $14,342 with an annual interest rate of 2.7%. He had 5 years left in college before he began repaying the loan. To find his subsidized monthly payment, we need to first calculate the total amount he owes after 5 years and then divide that by the number of months in the repayment period.

1. Convert the annual interest rate to a decimal: 2.7% ÷ 100 = 0.027
2. Calculate the interest for one year: $14,342 × 0.027 = $387.234
3. Calculate the total interest for 5 years: $387.234 × 5 = $1,936.17
4. Add the interest to the principal amount: $14,342 + $1,936.17 = $16,278.17
5. Assume a standard repayment period of 10 years (120 months) after graduation.
6. Divide the total amount owed by the number of months in the repayment period: $16,278.17 ÷ 120 = $135.65
