Answers

Answer:

hello your question has a missing diagram attached below is the missing diagram

answer :  

Mark the point of intersection S of circles R and P, and construct line QS ( option 2 )

Step-by-step explanation:

when constructing a tangent line from one point ( lets say Q as seen in the question ) to a circle P. The next step should be to mark a point of intersection between  the given circles and then construct a line through it

Answer:

Mark the point of intersection S of circles R and P, and construct line QS.

Step-by-step explanation:

This is correct because after you create circle R that intersects circle p, you're supposed to mark the intersection points.  If your in FLVS, it would be in lesson 7.04.  I also got this right on my test.  Good luck!

2/3 - 3/2y + 1/3y + 4 = 0​

Answers

Answer:

y = 4

Step-by-step explanation:

(2/3 + 4) + (-3/2y + 1/3y) = 0

(-3/2y + 1/3y) = -4 2/3

-9/6y + 2/6y = -14/3

-7/6y = -14/3

cross-multiply:

-21y = -84

y = 4

Answer:

y = 4

Step-by-step explanation:

Please use parentheses for clarity, remembering what big differences they make in expression values.

I will assume that your "2/3 - 3/2y + 1/3y + 4 = 0​" actually means

2/3 - (3/2)y + (1/3)y + 4 = 0​

The LCD here is 6, which is the product of the denominators 2 and 3.

Then your "2/3 - 3/2y + 1/3y + 4 = 0​" becomes:

                     4  - 9y    + 2y + 24 = 0, which simplifies to:

                     28 - 7y = 0.  Solving this, we get y = 4

Victor sold cupcakes and cookies yesterday. Each cupcake sold for $2.25 and each cookie sold for $0.50. At the end of the
day, Victor had sold $95.25 worth of cookies and cupcakes. If he sold 68 cupcakes and cookies combined, how many
cupcakes were sold and how many cookies were sold?

Answers

answer:number of cupcakes sold is 13  Number of cookies sold is 27  

Step-by-step explanation:

Let x represent the number of cupcakes that Victor sold.  Let y represent the number of cookies that Jane sold.  Each cupcake sold for $2.25 and each cookie sold for $0.50. At the end of the day,  This mean Victor had 2.25x 0.5y = 42.75 - - - - - - - - - -1she sold 40 cupcakes and cookies combined, it means thatx y = 40Substituting x = 40 - y into equation 1, it becomes2.25(40 - y) 0.5y = 42.7590 - 2.25y 0.5y = 42.75- 2.25y 0.5y = 42.75 - 90- 1.75y = - 47.25y = - 47.35/-1.75y = 27x = 40 - yx = 40-27 = 13

An equation is formed when two equal expressions. The number of cupcakes that Victor sold is 35, while the number of cookies that Victor sold is 33.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the number of cupcakes sold be represented by x, while the number of cookies sold is represented by y.

Now, the total number of cupcakes and cookies sold combined is equal to 68. Therefore, the equation can be written as

x + y = 68

x = 68 - y

Also, Each cupcake sold for $2.25 and each cookie sold for $0.50. And the total sale that Victor made is of $95.25. Therefore, the equation can be written as,

2.25x + 0.50y = 95.25

2.25(68 - y) + 0.5y = 95.25

153 - 2.25y + 0.5y = 95.25

-2.25y + 0.5y = 95.25 - 153

1.75y = 57.75

y = 33

Now, substitute the value of x in the first equation.

x + y = 68

x + 33 = 68

x = 35

Hence, the number of cupcakes that Victor sold is 35, while the number of cookies that Victor sold is 33.

Explica por qué cada figura está en el lugar que
eliges. Los términos son: cuadrilátero, cuadrado
rombo, rectángulo y paralelogramo​

Answers

Answer:

El orden es;

1) Cuadrilátero, 2) Rombo, 3) Paralelogramo, 4) Rectángulo, 5) Cuadrado

Step-by-step explanation:

Los términos dados son;

Cuadrilátero; Una forma con cuatro lados

Rombo; Un cuadrilátero con cuatro lados iguales

Cuadrado; Un cuadrilátero con cuatro lados iguales y cuatro ángulos iguales y dos lados paralelos opuestos

Rectángulo; Un cuadrilátero con cuatro ángulos rectos y dos lados paralelos opuestos

Paralelogramo; Un cuadrilátero con un par de lados paralelos opuestos

Observamos que todos los términos son cuadriláteros, por lo tanto, el cuadrilátero es el primer término

Por lo tanto, tenemos,

La primera forma es el cuadrilátero,

El cuadrilátero se transforma en un rombo (un cuadrilátero con lados iguales)

El ángulo del rombo se ajusta para dar un paralelogramo

El ángulo de paralelogramo dado cuatro ángulos iguales de 90 ° para dar un rectángulo

El rectángulo se ajusta para dar un cuadrado con todos los lados iguales

Gilbert purchased a car for 34000. The car depreciates at a rate of 14% per year. The exponential function that represents this situation is y = 34000(0.86)^x.

What is the change factor for this function?

Answers

Answer:

.86

Step-by-step explanation:

Exponential function formula

[tex]y = a ( 1 + or - r ) ^t[/tex]

where a = initial value

r = rate of change

and t = number of years

given the equation y = 34000(0.86)^x.

r = .86

Hence the change factor is .86

How are imperialized people viewed by the writer? Implement the above in c++, you will write a test program named create_and_test_hash.cc . Your programs should run from the terminal like so:./create_and_test_hash should be "quadratic" for quadratic probing, "linear" for linear probing, and "double" for double hashing. For example, you can write on the terminal:./create_and_test_hash words.txt query_words.txt quadratic You can use the provided makefile in order to compile and test your code. Resources have been posted on how to use makefiles. For double hashing, the format will be slightly different, namely as follows:./create_and_test_hash words.txt query_words.txt double The R value should be used in your implementation of the double hashing technique discussed in class and described in the textbook: hash2 (x) = R (x mod R). Q1. Part 1 (15 points) Modify the code provided, for quadratic and linear probing and test create_and_test_hash. Do NOT write any functionality inside the main() function within create_and_test_hash.cc. Write all functionality inside the testWrapperFunction() within that file. We will be using our own main, directly calling testWrapperFunction().This wrapper function is passed all the command line arguments as you would normally have in a main. You will print the values mentioned in part A above, followed by queried words, whether they are found, and how many probes it took to determine so. Exact deliverables and output format are described at the end of the file. Q1. Part 2 (20 points) Write code to implement double_hashing.h, and test using create_and_test_hash. This will be a variation on quadratic probing. The difference will lie in the function FindPos(), that has to now provide probes using a different strategy. As the second hash function, use the one discussed in class and found in the textbook hash2 (x) = R (x mod R). We will test your code with our own R values. Further, please specify which R values you used for testing your program inside your README. Remember to NOT have any functionality inside the main() of create_and_test_hash.ccYou will print the current R value, the values mentioned in part A above, followed by queried words, whether they are found, and how many probes it took to determine so. Exact deliverables and output format are described at the end of the file. Q1. Part 3 (35 points) Now you are ready to implement a spell checker by using a linear or quadratic or double hashing algorithm. Given a document, your program should output all of the correctly spelled words, labeled as such, and all of the misspelled words. For each misspelled word you should provide a list of candidate corrections from the dictionary, that can be formed by applying one of the following rules to the misspelled word: a) Adding one character in any possible position b) Removing one character from the word c) Swapping adjacent characters in the word Your program should run as follows: ./spell_check You will be provided with a small document named document1_short.txt, document_1.txt, and a dictionary file with approximately 100k words named wordsEN.txt. As an example, your spell checker should correct the following mistakes. comlete -> complete (case a) deciasion -> decision (case b) lwa -> law (case c)Correct any word that does not exist in the dictionary file provided, (even if it is correct in the English language). Some hints: 1. Note that the dictionary we provide is a subset of the actual English dictionary, as long as your spell check is logical you will get the grade. For instance, the letter "i" is not in the dictionary and the correction could be "in", "if" or even "hi". This is an acceptable output. 2. Also, if "Editors" is corrected to "editors" that is ok. (case B, remove character) 3. We suggest all punctuation at the beginning and end be removed and for all words convert the letters to lower case (for e.g. Hello! is replaced with hello, before the spell checking itself).Do NOT write any functionality inside the main() function within spell_check.cc. Write all functionality inside the testSpellingWrapper() within that file. We will be using our own main, directly calling testSpellingWrapper().
