ask me questions

Answer 1

ill help as best I can

Answer 2

1st point: ___6___ 2nd point:___-2___ 3rd point: ___-7___ Using the points above as zeros, construct the polynomial function, f(x), that will be the path of your roller coaster. Show all of your work. Using both fundamental Theorem and Descartes` rule of signs, prove to the construction foreman that your funtion matches your graph. Use complete sentences. Solve for the y–intercept for your function, f(x), and then construct a rough graph of your roller coaster. If your y–intercept is off the graph, give the coordinates of the y–intercept. HELP??

Answer 3

uhm wow. Okay, what's the first step to this, you must kno the formula, since it's your question?

Answer 4

First, think of "the foundation" as being the x-axis. In other wordsd, the roller coaster touches the x- axis at -7, at -2 and at 6, but does not go beneath the x-axis.

Thus, you automatically have three on the curve formed by the roller coaster.

Are you aware that a root of 6 corresponds to the factor (6,0) of the polynomial in question?

What are the other two factors, following this pattern?

You can obtain the polynomial in question by multiplying out the three factors mentioned.

Answer 5

How do I figure this out?

Tom has eight red balls. He has two less balls then green balls. He has 189 more green balls then red balls. He has 12 pink marbles. How many balls does he have ALTOGETHER?

Answer 6

would a toaster with piece toast in it would it be scale drawing or representational diagram

Answer 7

ONE AT A TIME, @autumnlynn12 was first.

Answer 8

x^3+3x^2-40x-84=f(x) that is what i got for the first question

Answer 9

Alright alright

Answer 10

Okay, is it a multiple choice?

Answer 11

no :(

Answer 12

Answer 13

@autumnlynn12 (6,0) and (-2,0) and (-7,0) are points on the x-axis; they're not factors.
what I was trying to tell you was that if one root is 6, one factor is (x-6); if another root is -2, the corresponding factor is (x-[-2]). What is the third factor?

To get started finding your polynomial, please multiply together (x-6) and (x+2).

Answer 14

OMG I'm so sorry my PC is messed up

Answer 15

-_- @Pollylovesschool go away, or be reported for spamming, dont reply, im trying to help

Answer 16

that is x^2-4x-12 that is simplified

Answer 17

Did you see my above message. I'm so sorry, my PC is so mess up. Please forgive me!!

Answer 18

messed*

Answer 19

x^2-4x-12

Answer 20

So, now you have three horiz. intercepts, (6,0) and (-2,0) and (-7,0) , and you have three factors, (x-6),(x+2) and (x+7).

Now, with x^2-4x-12 in hand, multiply this polynomial by the third factor, (x+7). Combine like terms. Write your function so that all powers of x are in descending order.

Then you'll have your polynomial.

Answer 21

Never mind. I'll go ask someone else. I know you are too upset to help. Sorry again! :(

Answer 22

yeah that is x^3+3x^2-40x-84

Answer 23

Close!
Your function / your polynomial is f(x)=x^3 + x^2 -28x -12x - 84 . Nice work!

Answer 24

but you did not simplify?

Answer 25

x^3+x^2-28x-12x-84

Answer 26

thats still not simplified do you not have to? because -28x-12x can be combined

Answer 27

Then do so, you know what to do!

Answer 28

ok! Using both fundamental Theorem and Descartes` rule of signs, prove to the construction foreman that your funtion matches your graph. Use complete sentences.
what about this part
