Step-by-step explanation

Exterior angle theorem:

d = a + b

d = 70 + 50

d = 120

Answer: TUY: 120°

Step-by-step explanation:

Hello,

1. Recall that the sum of a triangle’s angles is 180°, regardless of the type of triangle.

2. Find TUS, that is, the angle for U.

U = 180°-(50°+70°)=60°

For TUY:

Knowing that U=60° and that the line above U is 180°:

180°-60°=120°

Find the value of the expression 12y - 2xy, when x = 5 and y = 10.

Answers

Answer: 20

12y - 2xy

Insert values into equation

12(10) - 2(5)(10)

120 - 2(50)

120 - 100

20

Answer:

12y-2xy

x=5, y=10

(12x10) -(2x5x10)

=120-100

=20

Step-by-step explanation:

1.first collect the information you have been given in the question to make answering of the question easy.

2.then substitute the x value (in this case 5) and the y value (10) into the expression 12y - 2xy on there respectful positions.

3.having done so, you can then multiply and thereafter subtract as the question requires you to do.

Note: only substitute the y and x values where y and x appear in the question.

Always start with multiplying, after substituting,before subtracting or adding.

Find the length of the third side. If necessary, round to the nearest tenth. 16 23

Answers

Answer:

[tex]\sqrt{273}[/tex] units

Step-by-step explanation:

Use the Pythagorean Theorem: a^2 + b^2 = c^2

you have that a = 16 and c = 23, so:

16^2 + b^2 = 23^2

256 + b^2 = 529

b^2 = 273

b = [tex]\sqrt{273}[/tex]

5. The table below represents a quadratic function: draw a graph plot points

What would be the axis of symmetry for the equation?
What is the vertex?
What are the roots?
What is the y-intercept?

Answers

Answer:

The extreme point ( maximum or minimum ) of a parabola is called the vertex, and the axis of symmetry is a vertical line that passes through the vertex. The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function.

Step-by-step explanation:

The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

Suppose that a piano costs $5,000 and loses 20% of its value each year. What will be the value of the piano after 16 years? A. $219.90 B. $274.88 C. $140.74 D. $175.92

Answers

The answer is c 140.74 bucks or pound

Based on the information given will be the value of the piano after 16 years is : C. $140.74.

Using this formula

Time=Principal(1-rate)^n

Where:

Principal=$5,000

Rate=20%

Number of year=16 years

Let plug in the formula

Time=5,000(1-0.20)^16

Time=5,000(.80)^16

Time=$140.737

Time= $140.74 (Approximately)

Inconclusion the value of the piano after 16 years is : C. $140.74.

Build a class and a driver for use in searching your computers secondary storage (hard disk or flash memory) for a specific file from a set of files indicated by a starting path. Lets start by looking at a directory listing. Note that every element is either a file or a directory.Introduction and DriverIn this assignment, your job is to write a class that searches through a file hierarchy (a tree) for a specified file. Your FindFile class will search a directory (and all subdirectories) for a target file name.For example, in the file hierarchy pictured above, the file "lesson.css" will be found once in a directory near the root or top-level drive name (e.g. "C:\") . Your FindFile class will start at the path indicated and will search each directory and subdirectory looking for a file match. Consider the following code that could help you build your Driver.java:String targetFile = "lesson.css";String pathToSearch ="C:\\WCWC"; FindFile finder = new FindFile(MAX_NUMBER_OF_FILES_TO_FIND);Finder.directorySearch(targetFile, pathToSearch);File SearchingIn general, searching can take multiple forms depending on the structure and order of the set to search. If we can make promises about the data (this data is sorted, or deltas vary by no more than 10, etc.), then we can leverage those constraints to perform a more efficient search. Files in a file system are exposed to clients of the operating system and can be organized by filename, file creation date, size, and a number of other properties. Well just be interested in the file names here, and well want perform a brute force (i.e., sequential) search of these files looking for a specific file. The way in which well get file information from the operating system will involve no ordering; as a result, a linear search is the best we can do. Wed like to search for a target file given a specified path and return the location of the file, if found. You should sketch out this logic linearly before attempting to tackle it recursively.FindFile Class InterfaceFindFile(int maxFiles): This constructor accepts the maximum number of files to find.void directorySearch(String target, String dirName): The parameters are the target file name to look for and the directory to start in.int getCount(): This accessor returns the number of matching files foundString[] getFiles(): This getter returns the array of file locations, up to maxFiles in size.RequirementsYour program should be recursive.You should build and submit at least two files: FindFile.java and Driver.java.Throw an exception (IllegalArgumentException) if the path passed in as the starting directory is not a valid directory.Throw an exception if you've found the MAX_NUMBER_OF_FILES_TO_FIND and catch and handle this in your main driver. Your program shouldn't crash but rather exit gracefully in the unusual situation that we've discovered the maximum number of files we were interested in, reporting each of the paths where the target files were found.The only structures you can use in this assignment are basic arrays and your Stack, Queue, or ArrayList from the previous homeworks. Do not use built-in data structures like Java's ArrayList. To accomplish this, put in the following constructor and method to your ArrayList, Stack, or Queue:public ArrayList(Object[] input) { data = input; numElements = input.length;}public Object get(int index) { return data[index];} Which statement accurately describes viscosity?
