Answer:
-11
Step-by-step explanation:
The answer to the first one sould be -11
2x^3 +5x^2−x−6
Write 5x^2 as 4x^2 + x^2......and we have.....
2x^3 + 4x^2 + x^2 - x - 6
2x^2 ( x + 2) + ( x + 2)(x - 3)
(x + 2) [ 2x^2 + x - 3]
(x + 2) (2x +3) (x - 1)
x^3−4x^2−3x+18 = 0
Using some synthetic division, we have
3 [ 1 - 4 -3 18 ]
3 -3 -18
_______________
1 -1 -6 0
The remaining polynomial is x^2 - x - 6 which factors as (x - 3) ( x + 2)
So .... the factored form is (x - 3) ( x - 3) ( x + 2) = ( x + 2) ( x - 3)^2 = 0
Answer: 11.008
Step-by-step explanation: The 3 goes into the other 3 1 time. 3-3 is 0. Bring down the other 3. 3 goes into 3 one time. 3-3 is zero. Bring down the zero. 3 goes into 0, 0 times. 0-0 is 0. Bring down the two. 3 goes into 2 zero times. 2-0 is 2. Bring down 4. 3 goes into my 24 8 times.
Plastic sphere volume=4/3 times pi times rasius^3
4/3 times 3.14 times 18^3=24416.6
rubber ball whole=4/3 times 3.14 times 22^3=44579.6
subtract
44579.6-24416.6=20163
the answer is 20163 in^3
The answer is B. It is a result of the survey.
