The polynomial equation x cubed + x squared = negative 9 x minus 9 has complex roots plus-or-minus 3 i. What is the other root?

natta225 [31]

Answer:

-1

Step-by-step explanation:

The attached result from a graphing calculator shows the other root to be ...

x = -1

The "system of equations" consists of one equation for the left side function, and one equation for the right side function. The graphs of the two equations intersect at the point where the left and right parts of the given equation are equal to each other. The graphs intersect at x=-1.

Additional comment

We prefer to subtract one side of the equation from the other, so we have a single function whose value is 0 at the root of interest. Here, that would be ...

(x^3 +x^2) -(-9x -9) = 0

x^2 +x^2 +9x +9 = 0

We would graph y = x^3 +x^2 +9x +9 and have the graphing calculator identify the x-intercept. This is shown in the second attachment. No "system of equations" is required for this.

Find the scale factor

Dmitry_Shevchenko [17]

Answer:

the scale factor is penguin

jkjk the scale factor is 1/2

Step-by-step explanation:

to find the scale factor you take the coordinates of the image and divide it by the coordinates of the preimage

ex. A' coordinates are (3,1)

A coordinates are (6,2)

3/6=1/2

1/2=1/2

therefore the scale factor is 1/2

hope this helps :)

Find the size of each of 6 payments made at the end of each year into a 6% rate sinking fund which produces $82000 at the end of

Yuri [45]

Answer:

at the end of 1st year we pay $ 11756

at the end of 2nd year we pay $ 24217

at the end of 3rd year we pay $ 37426

at the end of 4th year we pay $ 51427

at the end of 5th year we pay $ 66269

at the end of 6th year we pay $ 82001

Step-by-step explanation:

Given data

rate ( i ) = 6%

Future payment = $82000

no of time period ( n ) = 6

to find out

size of all of 6 payments

solution

we know future payment formula i.e.

future payment = payment per period ( $(1 + rate)^{n}$ - 1 ) / rate

put all these value and get payment per period

payment per period = future payment × rate / ( $(1 + rate)^{n}$ - 1 ) / rate

payment per period = 82000 × 0.06 / ( $(1 + 0.06)^{6}$ - 1 ) / rate

payment per period = 82000 × 0.06 / 0.4185

payment per period = $ 11756.27

at the end of 1st year we pay $ 11756

and at the end of 2nd year we pay $ 11756 × ( 1 + 0.06) + 11756

and at the end of 2nd year we pay $ 24217

and at the end of 3rd year we pay $ 24217 × ( 1 + 0.06) + 11756

and at the end of 3rd year we pay $ 37426

and at the end of 4th year we pay $ 37426 × ( 1 + 0.06) + 11756

and at the end of 4th year we pay $ 51427

and at the end of 5th year we pay $ 51427 × ( 1 + 0.06) + 11756

and at the end of 5th year we pay $ 66269

and at the end of 6th year we pay $ 66269 × ( 1 + 0.06) + 11756

and at the end of 6th year we pay $ 82001
