What is the remainder when the polynomial 6x2+11x−3 is divided by 2x−1?
o-na [289]

Answer: 4

There are three different ways to find the remainder.  Since I don't know which lesson you are working on, I will show you all three methods.

<u>Long Division:</u>

           <u>3x  +  7      </u>

2x - 1 ) 6x² + 11x - 3

       -  <u>(6x²  -  3x)</u>   ↓

                    14x  - 3

                -   (<u>14x  - 7)</u>  

                              4    

<u>Synthetic Division:</u>

2x - 1 = 0   ⇒   x = \frac{1}{2}


\frac{1}{2}   | 6      11     -3

    <u>| ↓       3     7</u>

      6      14    4

<u>Remainder Theorem:</u>

2x - 1 = 0   ⇒   x = \frac{1}{2}

f(x) = 6x² + 11x - 3

f(\frac{1}{2}) = 6(\frac{1}{2})² + 11(\frac{1}{2}) - 3

      = 6(\frac{1}{4}) + \frac{11}{2} - 3

      = \frac{3}{2} + \frac{11}{2} - \frac{6}{2}

      = \frac{8}{2}

      = 4

Find the mean of the rainfall amounts .
anygoal [31]

Answer:

2.25 inches

Step-by-step explanation:

The mean, or the average, or the rainfall amounts, can be found by adding all of the amounts together and dividing by the number of amounts. In this case, \frac{3+2+1+3}{4}=\frac{9}{4}=2.25. Hope this helps!
