x + 2 is not a factor of the polynomial and - 2 is <u>not a root</u> of the function.

<h3>Synthetic subdivision of the polynomial</h3>

The synthetic subdivision of the polynomial is calculated as follows;

if -2 is a root, then x + 2 is a factor of the polynomial.

                                           

                                        -3x³ + 6x² - 10x + 17

                                      --------------------------------------

                        x + 2   √-3x⁴ + 2x² - 3x + 4

                                   - (-3x⁴ - 6x³)

                                   -----------------------------

                                              6x³ +  2x² - 3x + 4

                                           - (6x³  + 12x²)

                                           -----------------------------

                                                       -10x² - 3x + 4

                                                    - (-10x² - 20x)

                                                    ----------------------------

                                                                17x + 4

                                                           -  (17x  + 34)

                                                          -----------------------

                                                                        -30

The remainder is not equal to zero, thus, x + 2 is not a factor of the polynomial and - 2 is not a root of the function.

x + 2 is not a factor of the polynomial and - 2 is not a root of the function.

<h3>What is Synthetic subdivision of the polynomial?</h3>

A simplified method for dividing a polynomial by another polynomial of the first degree by writing down only the coefficients of the several powers of the variable and changing the sign of the constant term in the divisor so as to replace the usual subtractions by additions.

The synthetic subdivision of the polynomial is calculated as follows;

if -2 is a root, then x + 2 is a factor of the polynomial.

                                      -3x³ + 6x² - 10x + 17

                                     --------------------------------------

                      x + 2  ÷ -3x⁴ + 2x² - 3x + 4

                                  - (-3x⁴ - 6x³)

                                  -----------------------------

                                             6x³ +  2x² - 3x + 4

                                          - (6x³  + 12x²)

                                          -----------------------------

                                                      -10x² - 3x + 4

                                                   - (-10x² - 20x)

                                                   ----------------------------

                                                               17x + 4

                                                          -  (17x  + 34)

                                                         -----------------------

                                                                       -30

Thus, the remainder is not equal to zero, thus, x + 2 is not a factor of the polynomial and - 2 is not a root of the function.

barxatty [35]

Answer:

48,558

Step-by-step explanation:

The function which models the relationship between the elapsed time, t in years, since 2010 and the town's population, P(t), is given as:

P(t)=36800\cdot2^{^\dfrac{t}{25}}

Now, 2020-2010=10 Years

Therefore we are required to calculate the population of the town 10 years after.

To do this, we simply substitute t=10 in the function.

P(10)=36800\cdot2^{^\dfrac{10}{25}}}\\=48557.9\\\approx 48558

According to the model, the population in Fall River will be 48,558 in the Year 2020.
