What is
lim sin(x) in the graph shown?

Using composite figures, we can find that the area of the shape is 18unit² and the perimeter of the shape is 20 + √8 units.

A composite shape is a shape that is made by connecting a few polygons to form a different shape. These shapes or figures can be formed from a variety of shapes, including triangles, squares, quadrilaterals, etc. Divide a composite item into basic forms such a square, triangle, rectangle, or hexagon to get its area.

In essence, a composite shape is a combination of fundamental shapes. It goes by the name's "composite" or "complex" shapes.

In this composite figure,

We have 2 rectangles and a triangle.

Dimension of rectangle:

Base = 2units

Height = 2 units.

Hypotenuse = √ (2² + 2²)

= √8

Area of the triangle = 1/2 × b × h

= 1/2 × 2 × 2

= 2unit².

Now, the rectangles are equal in shape and size.

Dimensions are:

Length = 4 units

Breadth = 2 units.

Area = l × b

= 4 × 2

= 8unit².

We have 2 rectangles so total area = 2 × 8

= 16unit².

Total area of the shape = area of triangle + area of 2 rectangles

= 2 + 16

= 18unit²

Now coming to the perimeter of the shape, we have to find the sum of the measure of the sides of the shape:

So, we have

2 + 4 + 2 + 6 + 6 + √8

= 20 + √8 units.

Answer:

Let's start by using a proportion to find the total number of questions on the test. We know that Charles answered 23 questions correctly and received a grade of 92%, which means he missed 8% of the questions.

Let x be the total number of questions on the test. Then 8% of the questions that Charles missed can be expressed as 0.08x.

The number of questions that Charles answered correctly plus the number of questions he missed must add up to the total number of questions on the test:

23 + 0.08x = x

Simplifying and solving for x, we get:

0.92x = 23

x = 23 / 0.92

x ≈ 25

Therefore, the total number of questions on the test was approximately 25.

The measure of ∠CFE is 40°

To solve for triangle ∠CEF, we know that

Parallel to DE is BC

Arc length BD = 58°

Arc length DE = 142°

We can then draw a diameter across the center of the circle and give it a name as the first step. The diameter in this situation is line ZT.

The arcs BD and DE are split in half by the line ZT.

Which is:

Arc SC = 1/(1/2(arc BC) = 1/(58)

Arc SC = 29°

142 = 1/2(arc DE) + arc TE

Arc TE = 71°

Sum of the angles of a semicircle is 180 degrees: Arc SC + Arc CE + Arc TE

29° + Arc CE + 71° = 180°

Arc CE + 100° = 180°

Arc CE = 180-100

Arc CE = 80°

Angle inscribed equals half of angle intercepted

CFE = 1/2 of Arc CE

<CFE = 1/2(80)

< CFE = 40°

The solution to the system equation after it is solved, would be x = 3 and y = 7.

To solve the given system of linear equations:

8x - 3y = 3

3x - 2y = -5

We can use the method of substitution or elimination. In this case, I will use the elimination method.

First equation x 2:

16x - 6y = 6

Second equation x 3:

9x - 6y = -15

Now, subtract the second equation from the first equation to eliminate the y variable:

(16x - 6y) - (9x - 6y) = 6 - (-15)

16x - 9x = 21

7x = 21

x = 21 / 7

x = 3

Next, substitute the value of x back into either of the original equations to find the value of y.

8x - 3y = 3

8(3) - 3y = 3

24 - 3y = 3

-3y = -21

y = -21 / -3

y = 7

So, the solution to the system of equations is x = 3 and y = 7.

To verify that fxy = fyx for the given function f(x,y)=e^(x+y+3), we need to find the partial derivatives of f with respect to x and y, and then check if they are equal.

Let's begin by finding the partial derivative of f with respect to x (f_x): f_x = (∂f/∂x) = (∂/∂x) e^(x+y+3) = e^(x+y+3) * (∂/∂x) (x+y+3) [using chain rule] = e^(x+y+3)

Now, let's find the partial derivative of f with respect to y (f_y): f_y = (∂f/∂y) = (∂/∂y) e^(x+y+3) = e^(x+y+3) * (∂/∂y) (x+y+3) [using chain rule] = e^(x+y+3)

Now, let's find the mixed partial derivative of f with respect to x and y (f_xy): f_xy = (∂^2 f/∂y∂x) = (∂/∂y) e^(x+y+3) = e^(x+y+3) * (∂/∂y) (x+y+3) [using chain rule] = e^(x+y+3)

Similarly, the mixed partial derivative of f with respect to y and x (f_yx) can be found as: f_yx = (∂^2 f/∂x∂y) = (∂/∂x) e^(x+y+3) = e^(x+y+3) * (∂/∂x) (x+y+3) [using chain rule] = e^(x+y+3)

Now, we can see that fxy = fyx, as both are equal to e^(x+y+3). Hence, we have verified that the given function f(x,y)=e^(x+y+3) satisfies the condition fxy = fyx.

Answer: 5 (first round) + 25 (second round) + 125 (third round) + 625 (fourth round) = 780

So, at the end of 4 rounds, including Jacob himself, 780 people will have gotten fliers.

Step-by-step explanation: In the first round, Jacob hands out fliers to 5 people.

In the second round, each of the 5 people from the first round hands out 5 fliers to 5 other people. So, there are now 5 x 5 = 25 people with fliers (including the original 5).

In the third round, each of the 25 people from the second round hands out 5 fliers to 5 other people. So, there are now 25 x 5 = 125 people with fliers (including the original 5 and the 25 from the second round).

In the fourth round, each of the 125 people from the third round hands out 5 fliers to 5 other people. So, there are now 125 x 5 = 625 people with fliers (including the original 5, the 25 from the second round, and the 125 from the third round).

Answer: The problem states that the proportion of people who throw away a portion of what they buy at the grocery store is p = 0.4. We want to find the probability that the sample proportion exceeds a certain value, which we will denote as p-hat.

The sample size is n = 100, which is large enough to use the normal approximation to the binomial distribution.

The formula for the standard error of the sample proportion is:

SE = sqrt[p * (1 - p) / n]

Substituting the values given in the problem, we get:

SE = sqrt[0.4 * 0.6 / 100] = 0.049

To find the z-score corresponding to a sample proportion of , we use the formula:

z = (p-hat - p) / SE

Substituting the values given in the problem, we get:

z = ( - 0.4) / 0.049 = -2.04

Using a standard normal table, we find that the probability of obtaining a z-score of -2.04 or lower is 0.0207. Therefore, the probability that the sample proportion exceeds is approximately 0.0207, rounded to three decimal places.

Step-by-step explanation:

Answer:

Based on the information provided that one corner of the parallelogram measures 128 degrees, we can determine the measures of the other three angles x, y, and z.

In a parallelogram, opposite angles are congruent, which means that x and z are congruent to 128 degrees.

So, x = z = 128 degrees.

The sum of the measures of the interior angles of a parallelogram is always 360 degrees. Since x and z both measure 128 degrees, the sum of x and z is 2 * 128 = 256 degrees.

Therefore, we can find the measure of y by subtracting the sum of x and z from 360 degrees:

360 degrees - 256 degrees = 104 degrees

So, y measures 104 degrees.

To summarize:

x = z = 128 degrees

y = 104 degrees

The area of 0.6808 to its left using the Standard Normal Table.

steps: 1. Identify the area: In this case, the area to the left of the z-score is given as 0.6808.

2. Consult the Standard Normal Table: This table shows the area to the left of various z-scores, ranging from negative to positive values.

3. Locate the closest area value: Look for the value in the table that is closest to the given area (0.6808). The table is typically organized into rows and columns, with the row header representing the first two digits of the z-score and the column header representing the third digit.

4. Identify the z-score: Once you've found the closest area value, determine the corresponding z-score by combining the row and column headers where the value is located.

Upon checking the Standard Normal Table, the closest area value to 0.6808 is 0.6800, which corresponds to a z-score of 0.47.

Keep in mind that the Standard Normal Table may not have the exact area value of 0.6808, so you need to find the closest possible value.

In summary, the z-score with an area of 0.6808 to its left using the Standard Normal Table is approximately 0.47.

Buddy's answer of 19 feet for the maximum height of his punt is correct, based on the given quadratic function.

How to solve the question?

To determine the maximum height of the punt, we need to find the vertex of the parabolic function h(x) = −.02x² + 1.2x + 4, which represents the height of the football at any given horizontal distance x from the point of impact.

The vertex of a parabola in the form y = ax² + bx + c can be found using the formula x = -b / 2a, which gives the x-coordinate of the vertex, and then substituting that value into the function to find the corresponding y-coordinate.

In this case, we have a = -.02, b = 1.2, and c = 4. So the x-coordinate of the vertex is x = -b / 2a = -1.2 / (2*(-.02)) = 30, and the corresponding maximum height is h(30) = -.02(30)2 + 1.2(30) + 4 = 19 feet.

An association class is frequently required for a many-to-many relationship.

In object-oriented programming, an association class is a class that is used to represent an association between two or more other classes. An association class is typically used when the relationship between the other classes is many-to-many, which means that each instance of one class can be associated with multiple instances of another class, and vice versa.

For example, consider a database that stores information about students and the courses they are enrolled in. Each student can be enrolled in multiple courses, and each course can have multiple students.

To represent this many-to-many relationship between students and courses, we can create an association class called "Enrollment" that has attributes such as the date of enrollment and the grade received. The Enrollment class would have a many-to-one relationship with both the Student class and the Course class.

To find how many reams of paper the printing press used for each book, we need to divide the total number of reams used by the number of books printed.

Let's convert 2 1/3 reams of paper to an improper fraction:

2 1/3 = (2 × 3 + 1) / 3 = 7/3

So the printing press used 7/3 reams of paper to print 3 books. To find how many reams of paper were used per book, we can divide the total amount of paper used by the number of books:

(7/3) ÷ 3 = 7/9

Therefore, the printing press used 7/9 of a ream of paper for each book.

Gary's average speed is approximately 44.4 mph. This is found by dividing the total distance traveled (800 miles) by the total time taken (18 hours) and rounding to the nearest tenth.

In this case, the total distance is 800 miles, and the total time is 18 hours. So we can plug these values into the formula and simplify

Average speed = 800 miles ÷ 18 hours

Average speed = 44.444444... miles per hour

If we throw, a coin in twice, then pay off for throw exactly two heads is $120. The expected win value in the game in 742 trials is equals to the $1669.5.

We have to two tosses a coin and we gift with payouts according to results of tossing. When we throw exactly two heads in two tosses of a coin, then pay out is $120. If not throw two heads then payout is $37… Now, number of times we play the game that is trials = 742

We have to determine value of expected value to win or loss for 742 trials. First we determine the excepted value of proposition. Total possible outcomes on two tosses of a coin = 4 = {HH,TT, HT, TH}

Probability of throwing two heads = 1/4

= 0.25

Probability of not throwing two heads

= 1 - 1/4 = 3/4 = 0.75

That is when x (pay off) = $120, P( x)

= 0.25 ; x (payout) = -$37, P( X) = 0.75. Now, the excepted value formula is written as, [tex]E( x) = \sum x× P(x) [/tex]

= $120 × 0.25 - $37 ×0.75

= $2.25

So, the expected value of win with 575 trials of gane = 2.25 × 742

= 1669.5

Hence, required excepted win value is $1669.5.
