The equations which represents the circle are x²+ (y - 3)² = 36 and

x²+ (y + 8)² = 36.

What is equation of circle?

A circle is a shape made up of all points in a plane that are at a specific distance from the center point.

The standard form for finding the equation of a circle is expressed as follows:

[tex](x-a)^2 + (y-b)^2 =r^2[/tex]

In the equation,

(a, b) is the center of the circle

r is the radius of the circle

We are given that the diameter is 12 units. So,

Radius = 6 units

Since, the center lies on the y - axis so, the center will be of the form (0,b).

Now, on substituting this, we get

⇒ [tex](x-0)^2 + (y-b)^2 =6^2[/tex]

⇒ [tex]x^2 + (y-b)^2[/tex] = 36

So, we get the two equations as:

1. x²+ (y - 3)² = 36

2. x²+ (y + 8)² = 36

Hence, the first and the last option is the correct answer.

The statement that describes the mean number of hours worked through which the relation is satisfied is The mean is the highest number or hours worked by any students in the group

What about mean?

In mathematics, the mean is a measure of central tendency that represents the average value of a set of numbers. It is often called the arithmetic mean, and it is calculated by adding up all the values in the set and then dividing the result by the total number of values.

The formula for the mean is:

mean = (sum of all values) / (total number of values)

For example, suppose we have a set of four numbers: 2, 5, 8, and 11. To find the mean of this set of numbers, we add them up and divide by the total number of values:

mean = (2 + 5 + 8 + 11) / 4

mean = 26 / 4

mean = 6.5

Therefore, the mean of this set of numbers is 6.5. The mean is a commonly used measure of central tendency in statistics and data analysis, and it provides a way to summarize the general trend or average of a data set.

According to the given information:

Mean of the given condition is,

What is arithmetic sequence?

An arithmetic sequence is a sequence of numbers in which each term after the first is found by adding a fixed constant number, called the common difference, to the preceding term. For example, the sequence 2, 5, 8, 11, 14, ... is an arithmetic sequence with a common difference of 3, since each term after the first is found by adding 3 to the preceding term.

The nth term of an arithmetic sequence can be found using the formula:

an = a1 + (n-1)d.

The merchant received 7/10 of a pound of diamonds and divided them into 7 equal lots. To find the weight of each lot, we need to divide 7/10 by 7:

(7/10) ÷ 7 = (7/10) × (1/7) = 1/10

In Mathematics, a rotation is a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.

Additionally, the rotation of a point 90° about the center (origin) in a clockwise direction would produce a point that has these coordinates (y, -x).

Next, we would apply a rotation of 90° clockwise to the coordinate of quadrilateral ABCD as follows;

(x, y)                               →            (y, -x)

Coordinate A = (-3, 4) → Coordinate A' = (4, -(-3)) = (4, 3)

Answer:

M ≈ $933.24

Step-by-step explanation:

To calculate Marcus's monthly payment for financing his car for 5 years at an annual interest rate of 8.5%, we can use the formula for the monthly payment on a loan:

M = P * (r/12) * (1 + r/12)^n / ((1 + r/12)^n - 1)

where:

M is the monthly payment

P is the principal (in this case, $45,000)

r is the annual interest rate (in this case, 8.5%)

n is the number of monthly payments (in this case, 5 years * 12 months/year = 60 monthly payments)

Substituting the given values, we get:

M = $45,000 * (0.085/12) * (1 + 0.085/12)^60 / ((1 + 0.085/12)^60 - 1)

Using a calculator, we get:

M ≈ $933.24

Therefore, Marcus's monthly payment for financing his car for 5 years at an annual interest rate of 8.5% is approximately $933.24.

Answer: the length of TR is 24.5.

Step-by-step explanation: 9x + 1 = 13x - 11

22 = 4x

x = 5.5

Presently that we know x, ready to discover the values of PR and QS:

PR = 9x + 1 = 9(5.5) + 1 = 49

QS = 13x - 11 = 13(5.5) - 11 = 56

Since TR is half of the PR bisector, ready to discover it by separating PR by 2:

TR = PR/2 = 49/2 = 24.5

The empty set (also known as the null set) is a subset of every set because it does not contain any elements that are not in the set. In other words, if A is any set, then every element of the empty set is also an element of A, since the empty set contains no elements. This satisfies the definition of a subset, which states that for any two sets A and B, A is a subset of B if every element of A is also an element of B. Therefore, the empty set is a subset of every set.

Answer:

Thus, for making installment payments, the credit card holder incurred the additional cost of Option D.

Step-by-step explanation:

The credit card holder paid an additional D. $559.56 over the 12 months versus paying the balance in full before the end of the first month.

How is the additional payment determined?

The additional payment made by the credit card holder results from paying installments instead of clearing the balance in the first month.

Installment plans attract finance charges at an annual percentage rate (APR), which increases the total amount paid.

Therefore, the additional payment is the difference between the total installment payments and the credit card balance at the beginning of the first month.

N (# of periods) = 12 months

I/Y (Interest per year) = 11.99%

PV (Present Value) = $6,299.59

PMT (Periodic Payment) = $-350

Results:

FV = $3,009.15

Sum of all periodic payments = $3,850 ($350 x 11)

Total Interest = $559.57

The total amount paid over the 12 months = $6,859.15 ($3,009.15 + $3,850)

The total amount paid in full in the first month = $6,299.59

Additional payment made via installments = $559.56 ($6,859.15 - $6,299.59)

Thus, for making installment payments, the credit card holder incurred the additional cost of Option D.

The correct choice is (4) x² = 34² +29² - 2(34)(29)*cos(56).

Trigonometry is one of the branches of mathematics that deals with the relationship between the sides of a triangle (a right-angled triangle) and its angles. There are six types of trigonometry.

We can use the laws of cosines and sines to solve this problem.

According to the law of cosines, we have:

cos(B) = (a² c² - b²) / 2ac

where a, b and c are the  lengths of opposite sides of angles A, B and C. In this case, we get that a = 34, b = x, and c = 29, and we know that angle C is 56 degrees . Because:

cos(B) = (34² 29² - x²) / (23429)

According to the Law of Sines, we have:

sin(B) / b = sin(C) / c

Substituting the given values ​​we get:

sin(B) / x = sin(56) / 29

Solving Sin(B) we get:

sin(B) = x * sin(56) / 29

Now we can use the identity sin²(B) cos²(B) = 1 to eliminate sin(B) and solve for x:

(x * sin(56) / 29)² cos²(B) = 1

Expanding and substituting  cos(B) from the previous expression, we get:

(x² * sin²(56) / 29²) ((34² 29² - x²) / (2(34)(29))²= 1

Simplifying and solving for x², we get:

x² = 34²+ 29² - 2(34)(29)*cos(56)

Therefore, the correct choice is (4) x² = 34² +29² - 2(34)(29)*cos(56).

According to the information, we know that the term 125x^5y^4 appears in the expansion when n = 6 and the coefficient of x^6y^7 in the expansion is zero, and the x^6y^7 term does not appear in the expansion.

We know that the binomial expansion of (x-y)^n is given by the formula:

where nCk represents the binomial coefficient "n choose k".

We are given that the term 125x^5y^4 appears in the expansion, so we can set up an equation using the binomial coefficient for that term:

Simplifying this equation, we get:

We can solve for n by finding the smallest value of n for which nC5 is greater than or equal to 125. We can use the formula for binomial coefficients:

to calculate the values of nCk for different values of n and k. However, it is easier to use Pascal's triangle to find the binomial coefficients quickly. The fifth row of Pascal's triangle is:

We see that the sixth term of this row is 10C5 = 252, which is greater than 125. Therefore, we know that the term 125x^5y^4 appears in the expansion when n = 6.

To find the x^6y^7 term in the expansion, we need to find the coefficient of x^6y^7 in the expansion. We can use the same formula as before, but with k = 7 instead of k = 5:

We can simplify this expression using the fact that (-1)^7 = -1:

We want to find the value of this expression, so we need to find the value of n. We know that n = 6 because the term 125x^5y^4 appears in the expansion. Therefore, we can substitute n = 6 into the expression:

We see that 6C7 is zero because we cannot choose 7 items from a set of 6. Therefore, the coefficient of x^6y^7 in the expansion is zero, and the x^6y^7 term does not appear in the expansion.

To find the x^7y^2 term in the expansion, we can use the same formula as before, but with k = 2:

We can simplify this expression using the fact that (-1)^2 = 1:

We want to find the value of this expression, so we need to find the value of n. We know that n = 6 because the term 125x^5y^4 appears in the expansion. Therefore, we can substitute n = 6 into the expression:

The correct answer is: E. None of the above. The y-intercept and x-intercept will remain the same, and the consistent slope will not be affected by changes in the y value when x remains constant.

What is slope?

In mathematics, slope refers to the steepness or incline of a line on a graph. It is a measure of how much the dependent variable changes for every unit change in the independent variable.

If the y value decreases and the x value remains the same over time, this means that the slope remains constant. A consistent slope means that the relationship between the two variables is fixed, regardless of the values of the variables. Therefore, the y-intercept will not change as it only depends on the value of y when x=0. The x-intercept will also not change, as it only depends on the value of x when y=0.

Therefore, the correct answer is:

E. None of the above. The y-intercept and x-intercept will remain the same, and the consistent slope will not be affected by changes in the y value when x remains constant.

The maximum length of the poster that can be put in the box is 28 in.

Step-by-step explanation:

For given trapezoid, the measures of angles A, B, and D are 40 degrees and 50 degrees, respectively.

A trapezoid is a quadrilateral with one pair of parallel sides. The parallel sides are called the bases of the trapezoid, and the other two sides are called the legs. The legs may be of equal length, or they may be different lengths.

Since trapezoid ABCD has two parallel sides, we know that angle A + angle D = 180 degrees. Similarly, angle B + angle C = 180 degrees.

Therefore, we can write:

angle A + angle B + angle C + angle D = 360 degrees

Substituting angle A = angle B and angle C = angle D, we get:

2(angle A) + 2(angle C) = 360 degrees

Simplifying:

2(angle A) + 2(50)= 180 degrees

2(angle A) = 180 degree-100 degree

2(angle A) = 80 degree

angle A= 80 degree/2

angle A = 40 degree

Since we know that angle A = angle B

angle B= 40 degree

Therefore,

angle A = angle B = 40 degrees

angle D = angle C = 50 degrees

So the measures of angles A, B, and D are 40 degrees and 50 degrees, respectively.
