(2·4)+6÷2 need to know how to do this problem

Answer:

Step-by-step explanation:

For relations expressed as (input, output) or (x, y) pairs, the domain is the list of inputs, or x-values. The range is the list of outputs, or y-values. Yes, it is that simple. (We often like to arrange the lists in increasing order.)

__

1. Domain: {-1, 0, 1, 4}

  Range: {-6, 3, 5, 7}

__

2. Domain: {-1, 2, 3}

  Range: {3, 5, 7}

__

3. Domain: {-2, -1, 0, 1}

  Range: {0, 1, 4}

Hi! I'm happy to help!

Fractions are wholes that are split up. When you split the whole into more pieces, the pieces are smaller.

Due to the fact that 5/12 is split into more pieces than 5/11, and they have the same amount of pieces, 5/11 would be larger because of bigger pieces.

5/11 is bigger because it has bigger pieces.

I hope this was helpful, keep learning! :D

Answer:

W = 1.06 MJ

Step-by-step explanation:

- We will use differential calculus to solve this problem.

- Make a differential volume of water in the tank with thickness dx. We see as we traverse up or down the differential volume of water the side length is always constant, hence, its always 8.

- As for the width of the part w we see that it varies as we move up and down the differential element. We will draw a rectangle whose base axis is x and vertical axis is y. we will find the equation of the slant line that comes out to be y = 0.5*x. And the width spans towards both of the sides its going to be 2*y = x.

Answer:

x=118,095

Step-by-step explanation:

6 = 2[tex]e^{k*1}[/tex]

3 =  [tex]e^{k }[/tex]

ln(3) = k ln(e)

k = ln(3)

k = 1.09861

[tex]x = 2e^{1.09861*10}[/tex]

x = 2e^{10.9861}

[tex]x=2e^{10.9861}\quad \left[/tex]

x=118,095

Answer:

in this question, the mean would be the best measure for central tendency....

Step-by-step explanation:

because it is the measure that includes all the values in the data set for its calculation, and any change in any of the scores will affect the value of the mean. This is not the case with the median or mode.

So in conclusion your answer will be D.mean

Answer:

2.6+3.1+5.4 =21.1

if you have 20

subtract 21.1-20

then you have 1.1

since the difference is 1.1 then we say

21.1>20

Answer:

so the second one

4 * (-9) * (-3) * (-1)

Step-by-step explanation:

-2 * (-7) * 12 * 4 = positive

4 * (-9) * (-3) * (-1) = negative

-6 * (-7) * (-8) * 0 = positive

-3 * (-2) * (-4) * (-7) = positive

negative times negative = positive

Answer:

10 months. Each plan will save 800 dollars.

Step-by-step explanation:

500 + 30x = y

300 + 50x = y

You want the months to give the same amount of money. The x has to be the same for both

500 + 30x = 300 + 50x        Subtract 300 from both sides

500 - 300 + 30x = 50x         Combine

200 + 30x = 50x                   Subtract 30x from both sides

200 = 50x - 30x                    Combine

200 = 20x                              Divide by 20

x = 10

So in 10 months time the amounts will be the same. How much will there be?

500 + 30*10 = 500 + 300 = 800

300 + 50*10 = 300 + 500 = 800

Answer:

The better one is $6 for 24 oz bottle

Step-by-step explanation:

If it cost 4 dollars for a 12 oz bottle and that would cost 1 dollar per 3 oz but for the 6 dollar for a 24 oz bottle it would be 1 dollar per 4 oz so 6 dollars for a 24 oz bottle is better!

Answer:

10. f'(x) = (x/14) + (14/9)

11. f'(x) = - x + 2

12. f'(x) = 2x - 8

Step-by-step explanation:

The step to solving inverse is a simple trick. You must invert x and y.

For (10.) let f(x) = y

then y = 9x - 14

x = 9y - 14 (this is inverting x and y)

solving for y: x + 14 = 9y

therefore : y = (x/14) + (14/9)

You can do this for the others as well and using simple "solve for x" methods, you can solve for y which is f'(x).

Additional comment

The doubling time for continuously compounded interest is 69.3 years divided by the interest rate in %. Here, that is 69.3/7.3 = 9.49 years. That means an investment of 10 years will be slightly more than double the original amount. 2×65,000 = 130,000, so choice A is in the right ballpark. The other numerical choices are not.

Step-by-step explanation:

Answer:

The associative property can be used with multiplication and addition.

Examples:

2+(3+2) -> (2+3)+2 (Associative Addition)

2*(3*2) -> (2*3)*2 (Associative Mult.)

It does not work with division or subtraction.

2-(3-2) does not equal (2-3)-2

Answer:

A=-1/2

If you search it up, it will show you all the steps

Let start with some basic theory of quadratics

If  f(x)=ax2+bx+c  a,b,c ∈R  a≠0    f(x)=ax2+bx+c  a,b,c ∈R  a≠0  has   2    2   roots   r1    r1  and   r2    r2  than it can take the form f(x)=a(x−r1)(x−r2).f(x)=a(x−r1)(x−r2).

The maximum or minimum value of  f(x)    f(x)   is   M=−(b2–4ac)4a  M=−(b2–4ac)4a

If   a>0    a>0  then  M    M  is the minimum value and if   a<0    a<0   then   M    M  is the maximum value.

Lets go now to the question

Since  2    2  and   7    7  are the roots our function will be  f(x)=a(x−2)(x−7),  a∈R  f(x)=a(x−2)(x−7),  a∈R

so   f(x)=a(x2
