The function N(x) that represents the number of ounces of peanuts in the mixture is N(x)=x.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Given that, Amir has 48 ounces of cashews, walnuts, and pecans.

He adds x ounces of peanuts to create a mixture.

M(x) that represents the number of ounces of all nuts in the mixture.

M(x)=48

N(x) that represents the number of ounces of peanuts in the mixture.

So, N(x)=x

Now, (M/N)(x) = M(x)/N(x)

= 48/x

Therefore, the function N(x) that represents the number of ounces of peanuts in the mixture is N(x)=x.

Answer:

her saving that was left from June and July is 112

Step-by-step explanation:

The computation of the saving amount left is shown below;

= Total saving in 2 months - amount spent

= 175.30 + 132.50 - 195.80

= 112

Hence, her saving that was left from June and July is 112

What is the other number and do you have like a picture

Answer:

Question 3: d

Question 4: a

Step-by-step explanation:

Substitute the letters for the numbers that they give you.

3. 34 or D

4. A or 80

5. B or x/4

3. plug the n and x value so:

20+5(3)-1 **always do the parenthesis**

20+15-1= 35-1= 34

4. same thing as the last one:

5(4+3(4))

20+ 3(4)= 20+ 5*12= 20+60= 80

5. you divide whatever the bill is by 4

Answer: 284.7

Step-by-step explanation:

Step-by-step explanation:

radius of cone and hemisphere are the same

volume of half sphere=(1/2)*(4/3)*

                                   =(1/2)*(4/3)*3.14*                       (4*4*4=64)

                                   =133.97333

                                   =133.97

volume of cone= (1/3)h

                        =(1/3)*3.14**9                                      (4*4=16)

                        =150.72

total volume=133.97+150.72

                   =284.69

Answer:

the area is 804.25 feet

formula πr^2

Answer:

Polynomial product A:

(4x2 – 4x)(x2 – 4) Polynomial product B:

(x2 + x – 2)(4x2 – 8x)

They are trying to determine if the products of the two polynomials are the same. But they disagree about how to solve this problem.

1. Complete the table to summarize each student's conjecture about how to solve the problem. (2 points: 1 point for each row of the chart)

Classmate Conjecture

Emily: says they should just check one method

Zach: says that they should check all three bc there could be multiple answers

Evaluating the Conjectures

Who do you think is correct? (1 point)

If they do all of the methods correctly, they should get the same answer for all of them.

Analyzing the Data

Table Method:

2. Use the table to find the products of the two polynomials. Write your answer in descending order. (4 points: 2 points for each product)

A) (4x2 – 4x)(x2 – 4)

         4x2        –4x

x2      4x^4     –4x^3

–4     -16x^2     16x

4x^4 - 4x^3 - 16x^2 + 16x

B) (x2 + x – 2)(4x2 – 8x)

              x^2           x            -2

4x^2       4x^4      4x^3       -8x^2

-8x       -8x^3       -8x^2       16x

4x^4 - 4x^3 - 8x^2 - 8x^3 - 8x^2 +16x

combine like terms

4x^4 - 4x^3 - 16x^2 + 16x

3. Are the two products the same when you multiply them with the table method? (1 point)

yes

Multiplying Using the Distributive Property:

4. Multiply the two polynomials using the distributive property. (4 points: 2 points for each product)

5. Are the two products the same when you multiply them horizontally? (1 point)

yes

Making a Decision:

8. Who was right, Emily or Zach? Are the products the same with the three different methods of multiplication? (1 point)

Emily was correct. the products are the same no matter what method.

9. Which of these three methods is your preferred method for multiplying polynomials? Why? (1 point)

personally, i like the distributive property, but do whichever one you like.

Step-by-step explanation:

Answer:

11 up , 11 left

Step-by-step explanation:

Given

[tex](17, -9)[/tex] to [tex](6,2)[/tex]

Required

Determine the translation rule

Considering the x coordinates.

From 17 to 6

6 is to the left of 17.

Using the translation rule:

[tex]x = x' + b[/tex]

[tex]17 = 6 + b[/tex]

[tex]17 - 6 = b[/tex]

[tex]11 = b[/tex]

[tex]b = 11[/tex]

Hence: From 17 to 6 is 11 units left translation

Considering the y coordinates.

From -9 to 2

2 is at the top -9.

Using the translation rule:

[tex]y = y' + b[/tex]

[tex]-9 = 2 + b[/tex]

[tex]-9 - 2 = b[/tex]

[tex]-11= b[/tex]

[tex]b = -11[/tex]

The negative value impies a upward translation.

Hence: From -9 to 2 is 11 units up translation
