To solve for angle A and angle B in the given triangle, we can use the Law of Sines. The Law of Sines states that the ratio of the length of a side to the sine of its opposite angle is constant for all sides and angles in a triangle.

In this case, we have side a with length 2 and side c with length 9. Let's denote angle A as angle opposite side a and angle B as angle opposite side b (which is unknown).

Using the Law of Sines, we have:

sin(A) / a = sin(B) / b

Plugging in the known values, we get:

sin(A) / 2 = sin(B) / 9

To find angle A, we can use the arcsine function:

A = arcsin((sin(B) / 9) * 2)

To find angle B, we can rearrange the equation:

sin(B) = (sin(A) / 2) * 9

B = arcsin((sin(A) / 2) * 9)

Now we can calculate the angles using a calculator:

A ≈ 19.5 degrees (rounded to one decimal place)

B ≈ 84.1 degrees (rounded to one decimal place)

Therefore, angle A is approximately 19.5 degrees and angle B is approximately 84.1 degrees.

The 15 and 9 units side lengths of the parallelogram ABCD, and the 36° measure of the acute interior angle, A indicates the values of the ratios are;

1. AB:BC = 5:3

2. AB:CD = 1:1

3. m∠A : m∠C= 1 : 4

4. m∠B:m∠C = 4:1

5. AD: Perimeter ABCD = 3:16

A ratio is a representation of the number of times one quantity is contained in another quantity.

The shape of the quadrilateral ABCD in the question = A parallelogram

Length of AB = 15

Length of BC = 9

Measure of angle m∠A = 36°

Therefore;

1. AB:BC = 15:9 = 5:3

2. AB ≅ CD (Opposite sides of a parallelogram are congruent)

AB = CD (Definition of congruency)

AB = 15, therefore, CD = 15 transitive property

AB:CD = 15:15 = 1:1

3. ∠A ≅ ∠C (Opposite interior angles of a parallelogram are congruent)

Therefore; m∠A = m∠C = 36°

∠A and ∠D are supplementary angles (Same side interior angles formed between parallel lines)

Therefore; ∠A + ∠D = 180°

36° + ∠D = 180°

∠D = 180° - 36° = 144°

∠D = 144°

m∠A : m∠C = 36°:144° =1:4

m∠A : m∠C = 1:4

4. ∠B = ∠D = 144° (properties of a parallelogram)

m∠B : m∠C = 144° : 36° = 4:1

5. AD ≅ BC (opposite sides of a parallelogram)

AD = BC = 9 (definition of congruency)

The perimeter of the parallelogram ABCD = AB + BC + CD + DA

Therefore;

Perimeter of parallelogram ABCD = 15 + 9 + 15 + 9 = 48

AD:Perimeter of the ABCD  = 9 : 48  = 3 : 16

Answer: 5 feet

Step-by-step explanation:

The maximum length of the remainder has 15 bits. The generator polynomial of a cyclic code determines the number of check bits, the minimum Hamming distance, and the maximum length of the remainder.

The degree of the generator polynomial in binary BCH codes corresponds to the number of check bits in the code. Furthermore, the length of the code is determined by the generator polynomial and is given by (2^m)-1 where m is the degree of the generator polynomial.Let the generator polynomial be X16+1 and we are to determine the maximum length of the remainder. For this polynomial, the degree is 16 and the length of the code is (2^16)-1 = 65535. We know that the maximum length of the remainder is equal to the degree of the generator polynomial minus one, i.e. 15.So, the maximum length of the remainder has 15 bits.

To find the length of the curve y = 1 - cos x from x = 0 to x = 4π, we can use the arc length formula:

Arc length = ∫[sqrt(1 + (dy/dx)^2)] dx from a to b

First, find the derivative of y with respect to x:
dy/dx = d(1 - cos x)/dx = sin x

Now, substitute into the arc length formula:
Arc length = ∫[sqrt(1 + sin^2(x))] dx from 0 to 4π

This integral doesn't have an elementary function as its antiderivative, but we can use the elliptic integral of the second kind to evaluate it.

Arc length = 4 * E(4π, k) where E is the elliptic integral of the second kind and k = 1 (since k = sin^2(x) in our case).

Using a calculator, we find that E(4π, 1) ≈ 3.8202. So, the arc length is approximate:
Arc length ≈ 4 * 3.8202 ≈ 15.2808

Hence, the correct answer is B) 15.281.

A uniform distribution has the data values evenly distributed throughout the range of the data. A bimodal distribution has two very common data values seen in a dot plot or histogram as distinct peaks.

A Dot Plot, also called a dot chart or strip plot, is a type of simple histogram-like chart used in statistics for relatively small data sets where values fall into a number of discrete bins (categories). A dot plot is similar to a bar graph because the height of each “bar” of dots is equal to the number of items in a particular category.

A dot plot is a graphical display of data using dots: Dot Plot is a graph for displaying the distribution of quantitative variable where each dot represents a value. For whole numbers, if a value occurs more than once, the dots are placed one above the other so that the height of the column of dots represents the frequency for that value.

Group of 'n' friends is going to drive together.

Expected expenditure on gasoline and parking = $(15 + 20) = $35

Expected expenditure for lunch, tickets for museum and dinner

= (8 + 11 + 12) × n

= 31n

Expression representing total expenditure = 35 + 31n

This expression shows the expected expenditure on each friend = $31

Plus an extra expense on gasoline and parking = $35          

Therefore, Option (B) is the correct option.

Answer:

0.78

Step-by-step explanation:

The constant of proportionality is the "k" in y = kx.

y is the dependent variable (whatever you do to x changes y)

x is the independent variable (it doesn't change in relation to y)

Your pounds of apples is your x

Your cost is your y

From the first row: 0.78 = (k)(1), which simplifies to k = 0.78

If you want to test it out, pick another line:

y = kx

3.12 = (k)(4)

divide both sides by 4

k = 0.78

It's great when tables like this have something in the x column that is a 1...because then the y is also the k

The value of the fractions in the mixed fraction form is 3(⁷/₉), 4(⁷/₉), and 6(²/₅) respectively.

A mixed fraction is a fraction that is created by fusing a fraction with a whole number. The fraction is defined as the division of the whole part into an equal number of parts.

The given fractions 34/9, 43/9, and 32/5 can be written in the form of the mixed fraction as below:-

To write the fractions in the form of the mixed fraction first divide the fraction by the complete number and put the remainder on the numerator.

The given coordinates are X(5,-3), Y(4,-1) and Z(6,-2).

We need to classify ∠XYZ whether it is right, acute, or obtuse.

A cartesian plane or coordinate plane can be defined as a plane formed by the intersection of two coordinate axes that are perpendicular to each other. The horizontal axis is called the x-axis and the vertical one is the y-axis. These axes intersect with each other at the origin whose location is given as (0, 0). Any point on the cartesian plane is represented in the form of (x, y). Here, x is the distance of the point from the y-axis and y is the distance from the x-axis.

Now, X(5,-3), Y(4,-1) and Z(6,-2) can be plotted as given below:

The given points X(5,-3), Y(4,-1) and Z(6,-2) have positive x-coordinate and negative y-coordinate.

In the cartesian plane, the fourth quadrant positive x-coordinate and negative y-coordinate.

So, all points X(5,-3), Y(4,-1) and Z(6,-2) lie in the fourth quadrant.
