what the h**l are you trying to say?

OMG! Look who answered a math question!

Where do you go to school?

Wherever it is, it’s fuckedup. The school doesn’t learn you math or grammar

The correct way to write this is, “The answer, which you have given, is incorrect.”

 If you are going to write like this, you should use a quill.  If don’t have a quill then just write

"You fuckedup the answer!"

Everyone understands that and no one will criticize your grammar.  

BTW the answer is (4!)²

The rotations are independent.

To get the solution to the problem, you need to subtract 2 from your answer- 70-2=68.

this is because the path (SE, SE, SE, SE, NE, NE, NE, NE) and the path (NE, NE, NE, NE, SE, SE, SE, SE) are not possible on the grid.

I got the same answer, but i didn't understand your explanation. can you please elaborate?

When the expression $-2x^2-20x-53$ is written in the form $a(x+d)^2+e$, where $a$, $d$, and $e$ are constants, then what is the sum $a+d+e$?

-2x^2 - 20x - 53        we need to complete the square on x...factor out the "-2"

-2 (x^2  + 10x  + 53/2)      

Take 1/2 of 10  = 5....square it  = 25....add and subtract it inside the parentheses

-2 (x^2  +10x + 25  + 53/2  - 25)      factor the first three terms and simplify the rest

-2 [ ( x + 5)^2   + 3/2)      distribute the "-2"  back across the terms inside the parentheses

-2(x + 5)^2  - 3

So  a = -2, d  = 5  and e  = -3     and their  sum is  0

Diregarding my previous answer  - I didn't consider that all rotations were the same -  I think this is like the total number of arrangements of 10 people seated at a table...

We place "anchor" any shell in any position.....and we have 9! ways to place the other shells

So...the total arrangements  are 9!  = 362880

Bump....any help?

4.How many paths of minimum length are there from A to b in the grid below?

Notice that if we consider a move downward to the right as "Southeast" = "SE"  and a move  upward to the right as "Northeast" = "NE," we have the following possible set  of moves from A to B :

( SE,SE, SE, NE, SE, NE, NE, NE )

So...the total number of  possible minimum paths is given by choosing any four of eight positions in the set for "SE"  (or, alternatively, choosing any four of eight positions in the set for "NE" ) = 

C(8, 4)  =   70  possible minimum paths

Yes it is correct thank you very very much

The answer which you have given is incorrect

a * b  = 2a  - b^2

So

a * b  = a * 5  = 9

So...this implies that  b  = 5

So we have

2a - b^2 =  9

2a  - (5)^2   = 9

2a  - 25  = 9   add 25 to both sides

2a  =  34         divide both sides by 2

a  = 17

I liked the way you took the problem but it still says it is incorrect. Please help

OK....

The integers in the domain of f(x)  are  0, 1, 2, 3, 4

So

g(0)  = f(0)  -  0    =  0  - 0  =  0 

g(1)   = f(1)  - 1  =  0 - 1  = -1

g(2)  = f(2)  - 2  = 1 - 2  = -1

g(3)  = f(3)  - 3  =  3 - 3  = 0

g(4)  = f(4)  - 4  =  6 - 4  = 2

So...the distinct numbers in the range of  g(x)  are  { -1, 0, 2 }  ⇒ i.e., three values

Let f(x)=3x+4 and g(x)=2x-3. If h(x)=f(g(x)), then what is the inverse of h(x)?

f(g(x))  means to put the function g  into  f

h(x)  = f(g(x))  = 3 [ 2x - 3 ]  + 4   =   6x - 9 + 4  =  6x - 5

So

h(x)  = 6x  - 5      for  h(x), write y

y  = 6x  - 5        we want to get x by itself...add 5 to both sides

y + 5  = 6x       divide both sides by  6

[ y + 5 ] / 6    = x         "swap" x and y

[ x + 5 ] / 6  = y      and this is the inverse of  h
