ra1l [238]

Answer:

x^3-4x^2+25x-100

Step-by-step explanation:

We have 2 roots -5i and 4. Using the conjugate root theorem for the root -5i, we know that 5i should be another root

Combining the roots into a polynomial gives us:

(x+5i)(x-5i)(x-4)

Expand:

(x^2 + 25)(x-4)

x^3-4x^2+25x-100

levacccp [35]

Answer:

Step-by-step explanation:

firstly, we will draw diagram

we know that

centroid divides altitude into 2:1 form

Estimate 80,767 - 37,291 by first rounding each number to the nearest thousand.

N76 [4]

Answer:

$44000$

Step-by-step explanation:

Given the following question:

$80767-37291$

To estimate by the nearest thousand, we have to look at the thousand's place value and then look at the number next to it, to see if it's greater than five.

$80767-37291$

$80767$

$7 > 5$

$81000$

$37291$

$2 < 5$

$37000$

$81000-3700=44000$

$=44000$

Hope this helps.
