HAHA nice joke CU, 
But guest....
what do you not understand about these? do you have a specific question that we can help you with that does not include any math problems? 

do the see?

i dont know how to do the see...

Hint: Find the radius

Do that by putting it into standard form.

Actually out of \(5\cdot5\cdot5=125\)possible outcomes, there are 6 outcomes that result in winnings of $1700. They are \((300, 400, 1000), (300, 1000, 400), (400, 300, 1000), (400, 1000, 300), (1000, 300, 400)\)and \((1000, 400, 300)\) where the ordered triplets indicate the results of the first, second, and third spin, respectively. So the probability we are looking for is \(\frac{6}{125}\).

Just because all the angles are the same, it doesn't mean all the sides are the same.

I plotted it and found two solutions!

C  =  G - 3F

when

F  =  2x²+ 6x - 5

and  G = 3x² + 4

So we just have to substitute   2x²+ 6x - 5   in for   F   and   3x² + 4   in for   G

C  =  G - 3F

C  =  (3x² + 4) - 3(2x²+ 6x - 5)

C  =  (3x² + 4) - 3(2x²+ 6x - 5)

The next steps are to simplify expression.

First distribute the negative three to the terms in the parenthesees.

Second combine like terms.

sry to bug you but i will post another question in like a minute and this one i think i understand better i just need clarification 

Perfect!! 

i then got 

g(-2) = -8 

as my final answer?

is that better lol

Very close!! But be careful with your negative signs!

g(-2)  =  -4(-2)² - 3(-2) + 2

                                              Negative two squared is equal to positive four.

g(-2)  =  -4(4) - 3(-2) + 2

                                              Negative four times positive four equals negative sixteen.

g(-2)  =  -16  - 3(-2) + 2

                                              Negative three times negative two equals positive six.

g(-2)  =  -16  +  6  +  2

Now just calculate negative sixteen plus six plus two!

i got 

g(-2) = 16 - 6 + 2 

is that right??

g(x)  =  -4x² - 3x + 2

                                              Replace every  x  with  -2

g(-2)  =  -4(-2)² - 3(-2) + 2

Now what do you get if you calculate the right side of that equation?

hectictar can you help me again please??

Each digit must be a factor of 10000, so the only possible digits are 1, 2, 4, 5, and 8. Furthermore, since the prime factorization of 10000 is there must be exactly four digits of 5. Among the remaining three digits, we also need four factors of 2. We have the following cases.

Case 1: The remaining three digits are 1, 2, and 8.

We want to arrange the digits 5, 5, 5, 5, 1, 2, and 8. There are \(\frac{7!}{4!} = 210\) ways to arrange these digits.

Case 2: The remaining three digits are 1, 4, and 4.

We want to arrange the digits 5, 5, 5, 5, 1, 4, and 4. There are \(\frac{7!}{4! 2!} = 105\) ways to arrange these digits.

Case 3: The remaining three digits are 2, 2, and 4.

We want to arrange the digits 5, 5, 5, 5, 2, 2, and 4. There are \(\frac{7!}{4! 2!} = 105\) ways to arrange these digits.

Thus, there are a total of \(210 + 105 + 105 = \boxed{420}\) 7-digit numbers.

The only way to get 1700 is to land on 300, 400, then 1000, so the probability is 1/(5*4*3) = 1/60.

yea that's what i was thinking as well...i tried to do it with logs but like it doesnt have an equal sign so you can't really do much other than simplify the -3 and 4

this says somebody replied, but it doesn't show their reponse....

Hint: \((a^2-b^2)=(a+b)(a-b)\)

thank you for all the help!

hectictar had the correct answer :)

My guess:

Total number of arrangements of  0, 1, 6,  and  7   =   4!   =   24

For each of these, there are 2 possible choices for the first three digits.

So the total number of possibilities  =  24 * 2   =   48

Only one of these 48 possibilities is correct, so the probability that Fatima chooses the correct one is

1 / 48

----------(below is my reassurance that there are actually 24 ways to arrange the last 4 digits!)----------
