Answer:
Step-by-step explanation:
Divide the total number of cans (5022) by the number of homerooms (18) to get the number of cans collected by each homeroom:
5022 cans
---------------------- = 279 cans per homeroom
18 homerooms
Let's do this by Briot-Ruffini
First: Find the monomial root
x - 2 = 0
x = 2
Second: Allign this root with all the other coeficients from equation
Equation = -3x³ - 2x² - x - 2
Coeficients = -3, -2, -1, -2
2 | -3 -2 -1 -2
Copy the first coeficient
2 | -3 -2 -1 -2
-3
Multiply him by the root and sum with the next coeficient
2.(-3) = -6
-6 + (-2) = -8
2 | -3 -2 -1 -2
-3 -8
Do the same
2.(-8) = -16
-16 + (-1) = -17
2 | -3 -2 -1 -2
-3 -8 -17
The same,
2.(-17) = -34
-34 + (-2) = -36
2 | -3 -2 -1 -2
-3 -8 -17 -36
Now you just need to put the "x" after all these numbers with one exponent less, see
2 | -3x³ - 2x² - 1x - 2
-3x² - 8x - 17 -36
You may be asking what exponent -36 should be, and I say:
None or the monomial. He's like the rest of this division, so you can say:
(-3x³ - 2x² - x - 2)/(x - 2) = -3x² - 8x - 17 with rest -36 or you can say:
(-3x³ - 2x² - x - 2)/(x - 2) = -3x² - 8x - 17 - 36/(x - 2)
Just divide the rest by the monomial.
Answer:
1/8 (Decimal: 0.125)
Step-by-step explanation:
Answer:b
Step-by-step explanation:
(×+1)(×-1)
---------------
(×+1)(×+7)
=cancel (×+1) both the numerator and denominator then you are left with
(×-1)
-------
(×+7)
=(×-1)/(×+7)
To know for sure I’d need to see the bar graph. But with in the information present the answer would be 12.25% or 1/8
