Answer:
light takes 3×10^5 second s
so total seconds taken by the light =780×10^6/3×10^5
1 min=60sec
no. of min=2600/60
=43333min
Answer:
2 minutes
Step-by-step explanation:
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
You're mixing water and flour, following the rule that for each 4.5 cup of flour you add 10 cups of water.
Note that 10:4.5 is equivalent to 20/9.
