What is the missing reason in the proof?
Both C and D are incorrect.

Answer:

a is the answer as it has 2 constant terms in 3 variables

Step-by-step explanation:

constant means a no. (it doesnt changes)

ex. 2 , 7 etc

variable means a term (generally a letter) which changes, its value will differ.

in the equation you have given both have only 2 variables

have you posted all the options?

GOOD LUCK FOR THE FUTURE! :)

Answer:

The answer is below

Step-by-step explanation:

The total revenue from the sale of a popular book is approximated by the rational R(x) = 1100x^2/x^2 + 4, where x is the number of years since publication and the total revenue in millions of dollars. Use this function to complete parts a through d. (a) Find the total revenue at the end of the first year. $ million (b) Find the total revenue at the end of the second year. $ million (c) Find the domain of function R. Choose the correct domain below. {x | x is a real number and x greaterthanorequalto 0} {x | x is a real number and x lessthanorequalto 5} {x | x is a real number and x notequalto 2, x notequalto 5} {x | x is a real number and x notequalto 2}

Solution:

Revenue is the total money made from the selling of a product or item.

a) Given the revenue function:

[tex]R(x)=\frac{1100x^2}{x^2+4}[/tex]

At the end of the first year (i.e. x = 1), the venue is given as:

[tex]R(1)=\frac{1100(1)^2}{(1)^2+4} =220\\\\R(1)=\$ 220\ million[/tex]

b) At the end of the second year (i.e. x = 2), the venue is given as:

[tex]R(2)=\frac{1100(2)^2}{(2)^2+4} =220\\\\R(2)=\$ 550\ million[/tex]

c) The domain of the function is the value of the denominator for which the value of the denominator is not zero

x² + 4 ≠ 0

The domain is {x| x is a real number and x ≥ 0}

Answer:

15/28 loads of laundry needs to be washed.

Step-by-step explanation:

2/7 + 1/4

=  

2 × 4 + 1 × 7

7 × 4 + 4 × 7

=  

8/28 + 7/28

=  

8 + 7/ 28

=  

15/28

Answer:

Slope is 3/2 and y-intercept is +3

Step-by-step explanation:

slope = m

y intercept = b

Slope is 3/2 and y-intercept is +3

Answer:

If you collect all the terms of the sequence into a set, that set will always be discrete, because there's only countably many of them, and every interval is uncountable. So you could move outside of natural numbers to real numbers, but then it's no longer a sequence, it's just a function.

Step-by-step explanation:

10X+ 180= 500

10X= 500-180

10X= 320. .....divine both sides by 10 to solve for X

X = 32.

check

10(32)+180 = 500

320+180 =500

500 =500...confirmed

Answer:

first term = 2 ...(given)

second term = f (2) = f (2-1) * 5 = 1 * 5 = 5. .....[according to the formula f(n) = f (n -1) *5 ]

third term = f (3) = f ( 3 - 1 ) * 5 = 2 * 5 = 10

fourth term = f (4) = f (4 - 1) * 5 = 3 * 5.= 15

fivth term = f (5) = f ( 5 - 1) * 5 = 4* 5. =20

Answer:

  0.666... = 6/9 = 2/3

Step-by-step explanation:

The repeating decimal 0.666... can be turned to a fraction as follows.

Let x represent the value of the number. Then 10x is ...

  10x = 10(0.666...) = 6.666...

Subtracting x gives ...

  10x -x = 6.666... - 0.666... = 6.000...

  9x = 6

Dividing by 9 and simplifying, we have ...

  x = 6/9 = 2/3

__

It can be worthwhile to remember that  1/9 = 0.111... repeating.

Then 3/9 = 1/3 = 3(0.111...) = 0.333... repeating

and 6/9 = 2/3 = 6(0.111...) = 0.666... repeating

Most calculators will round the last digit of 2/3 so that it is a 7. So, you may see ...

  2 ÷ 3 = 0.6666667 or 0.66666666667

or something similar, depending on your calculator. It is up to you to recognize this as probably a representation of 2/3. Some calculators will display the number as a fraction, so you don't have to guess.

Additional comment

A similar method is used to convert repeating decimals of other lengths to fractions. In general you multiply by 10^n, where n is the number of repeating digits. Then proceed as above: subtract x, divide by the coefficient of x. You will find you are always dividing by a number that has as many 9's as there are repeating digits.

Answer: 6 2/3

Step-by-step explanation:

Julie has 10 yards of ribbon.She divides the ribbon into 3 equal parts. This means that each ribbon will be:

= 10/3

= 3 1/3

She then uses 2 of the pieces on gifts. The amount of ribbon that she use will be:

= 3 1/3 × 2

= 10/3 × 2

= 20/3

= 6 2/3

Answer:

6. c. 120

7. $6.45

Step-by-step explanation:

1. 150 x 0.20 = 30

2. 150- 30= 120

1. 43 x 0.15= 6.45

Given:

A  store manager purchased hoodies for $24.99 apiece.

He sells the hoodies for $32.

To find:

The markup percentage.

Solution:

We have,

Cost price (C.P.) = $24.99

Selling price (S.P.) = $32

We know that,

[tex]\text{Markup percentage}=\dfrac{S.P.-C.P.}{C.P.}\times 100[/tex]

[tex]\text{Markup percentage}=\dfrac{32-24.99}{24.99}\times 100[/tex]

[tex]\text{Markup percentage}=\dfrac{7.01}{24.99}\times 100[/tex]

[tex]\text{Markup percentage}=\dfrac{701}{24.99}[/tex]

[tex]\text{Markup percentage}\approx 28.05[/tex]

Therefore, the markup percentage is 28.05%.

Answer:

Monthly salary= $4,228

Step-by-step explanation:

Giving the following information:

Fixed salary= $2,500

Sales commission= 10%

Sales= $24,600

To calculate the monthly salary, we need to use the following formula:

Monthly salary= fixed income + commission

Commission= (24,600 - 15,000)*0.18

Commission= $1,728

Monthly salary= 2,500 + 1,728

Monthly salary= $4,228

Answer:

Sue = 13 - x

(18 + x) / 2

Step-by-step explanation:

Initial Number of sweets:

Tony = 18

Sue = 18

Sue Gives tony x ;

Tony = 18 + x

Sue = 18 - x

Sue eats 5 of her sweets :

Sue = 18 - x - 5

Sue = 13 - x

Tony eats half of his sweets:

(18 + x) / 2

the answer is B. 62°

the correct answer to the question is the answer is B. 62°

Answer:

1. Move the variables to one side: 3(-4+4) = -3n

2. Distribute. You will end up with 0 = -3n

3. Divide both sides by -3. n = 0

Step-by-step explanation:

Answer:

n=0

Step-by-step explanation:

3(-4+4)+5n=2n

first distribute

-12+12+5n=2n

combine like terms

5n=2n

subtract 2n on both sides

3n=0

divide by 3 on both sides

n=0/3

which is also equal to

n=0

Answer:

Step-by-step explanation:

Look at 3%2At%2B7=%28+-8+%29.

Moved these terms to the left  %28 +8+ %29

It becomes 3%2At%2B7%2B _green%28+8+%29=0.

Look at 3%2At%2B_red%28+7+%29%2_red%28+8+%29=0.

Added fractions or integers together

It becomes 3%2At% 2B % 28+15+%29=0.

Look at highlight_red%28+3%2At%2B15+%29=0.

Solved linear equation %28+3%2At%2B15=0+%29 equivalent to 3*t+15 =0

It becomes highlight_green%28+0+%29=0.

Result: 0=0

This is an equation! Solutions: t=-5.

Answer: t= -1/3

Step-by-step explanation:

3t+7=-8

subtract 7 from 7 and 8 (this cancels out the 7)

left with 3t = -1

divide 3 into 3t and -1

the 3 in 3t is canceled out, leaving us with t, therefore t= -1/3
