Write a polynomial function of degree 7 that has the given zeros : 6 multiplicity 3,-4i, i

Hello from MrBillDoesMath!

x^7 - 18 x^6 + 125 x^5 - 522 x^4 + 1852 x^3 - 3960 x^2 + 1728 x - 3456

See Discussion for details.

Discussion:

The polynomial is

(x-6)^3 * (x-4i)(x+4i)(x-i)(x+i)   =

x^7 - 18 x^6 + 125 x^5 - 522 x^4 + 1852 x^3 - 3960 x^2 + 1728 x - 3456

Thank you,

MrB

ummm seems that u didnt post the attachement !

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
