Complete the synthetic division problem below.
leva [86]

Answer:

B

Step-by-step explanation:

This was originally a third degree polynomial:

2x^3+4x^2-4x+6, to be exact.

When you divide by -3, you are basically trying to determine if x + 3 is a zero of that third degree polynomial.  The quotient is always one degree lesser than the polynomial you started with, and if there is no remainder, then x + 3 is a zero of the polynomial and you could go on to factor the second degree polynoial completely to get all 3 solutions.  To perform the synthetic division, you always first bring down the number in the first position, in our case a 2.  Then multiply that 2 by -3 to get -6.

-3|  2   4   -4   6

          -6

    2    -2

So far this is what we have done.  Now we multiply the -3 by the -2 and put that up under the -4 and add:

-3|  2   4   -4   6

          -6   6

    2    -2   2

Now we multiply the -3 by the 2 to get -6 and put that up under the 6 and add:

-3|   2   4   -4   6

           -6    6  -6

      2    -2   2   0

That last row gives us the depressed polynomial, which as stated earlier here, is one degree less than what you started with:

2x^2-2x+2

What is the volume of this?
ankoles [38]

The volume of a sphere = 4πr^3/3<span>

The volume of a half of sphere =  2</span>πr^3/3 = 2 π (27)/3 = 18π<span>

</span>The volume of a cone= π r^2 h/3 = π (9)(8)/ 3 = 24 π

Total volume = 18 π + 24π = 42π = 42 x 3.14 = 131.9 cm^3

There are 22 events at an indoor track and field meet. The ratio of track and events to field events is 8:3. How many of the eve
Minchanka [31]
16 track and events and 6 events. Since if it is 8:3 that means the total is 11, and 22 is double 11. The ration would double in size. Making 8:3 to 16:6. If you add 16 and 6, you would get 22 in all.
