f(x)=x^2-6x+8 and g(x)=x-2 solve f(x)=g(x) using a table of values.

is this for the upper bound ?

\(C = 2 \pi r\\ A = \pi r^2 = \dfrac{C^2}{4\pi}\\ C= \sqrt{4\pi A} = \sqrt{1600\pi}=40\sqrt{\pi}~cm\)

I think its a) 90 and b) 216

Please correct me and show me how to do this problem if I'm wrong

that's I thought I should do but I'm not sure if there's a better way

Here is a hint for anybody who wants to try it:

You can only make the sum of 10 in four different ways as follows:

6 + 2 + 2 = 10 - permutations =3! / 2! =3
5 + 3 + 2 = 10 - ....................  =3!      = 6
4 + 4 + 2 = 10 - ....................  =3! / 2! =3
4 + 3 + 3 = 10 - ....................  =3! / 2! =3

And you can only make the sum of 20 in eight different ways as follows:

9 + 9 + 2 = 20 - permutations = 3! / 2! =3
9 + 8 + 3 = 20 - ..................... = 3!       =6
9 + 7 + 4 = 20 - ..................... = 3!       =6
9 + 6 + 5 = 20 - ..................... = 3!       =6
8 + 8 + 4 = 20 - ..................... = 3! / 2! =3
8 + 7 + 5 = 20 - ..................... = 3!       =6
8 + 6 + 6 = 20 - ..................... =3! / 2!  =3
7 + 7 + 6 = 20 - ..................... =3! / 2!  =3

That is as far as I go!!!.

I think she has a card numbered 2,...,9 for each color (8 red cards numbered from 2-9, 8 blue cards numbere from 2-9 and 8 green cards numbered from 2-9)

You have 9 - 2 + 1 = 8 cards with red, blue and green colors. How are the 3 colors distributed among the 8 cards?

Or, should your cards be labeled 1 through 9?.

8^25 = 377 7893186295 7161709568  +

12^25 = 9539621 6644069012 9601298432

=9539999 4537255308 6763008000

Rom explains why in his concluding paragraphs.

Rom peeled and predigested the first banana for you. You are a big monkey now, so you need to learn how to peel and eat bananas on your own volition. Otherwise, you will never grow up to be big and smart. _{(Not that there is much hope for the smart part.)}

Rom may never see your question.

If you used his name in the first line you would have more hope of him seeing it.

When x = 8 we have (x-8) = 0

For any other value of x we have (x-8) is either positive or negative. If you square a positive number you get a positive number; if you square a negative number you get a positive number. 

but how do we prove that it is always 0 or positive?

i feel like an explanation is needed for the mark

When k = 8 we have \(f(x) = x^2-16x+64+1 \text{ or } f(x) = (x - 8)^2 + 1\)

No matter what the value of x is, (x-8)² is always zero or positive, Hence f(x) is always greater than zero.

.

This is it I think. Don't you have any blocks in the house that you can experiment with?

She already earns $200 so 10% of that gets saved which is $20

Anything over $200 that she earns automatically gets saved. So if she earnes and extra $x above the $200 then all of x will be saved

So she if she makes $x more next payday then this one then she will save 20+x dollars of it.

I know nothing of the class you're taking and just reading through these it seems pretty clear that a, b, and d are disadvantages.  So I guess (c) is the answer.

hello , bro,

May  know why you do derivative for ln(1+sinx)/x but ignore the derivative for atan^-1x+b???

Thanks Tertre

I suppose though I don't see any reason to use "n".

The word row is more descriptive of what's going on.
