Quotient: 2x⁵ + x⁴ + (1/3)x³ -(28/9)x² + (91/27)x – (361/81)

Remainder: 523/81

2) Since the division is not exact (remainder 523/81) the factor 3x + 1 (the divisor) is not a factor.

Explanation (Long division):

1)

6x⁶ + 5x⁵ + 2x⁴ - 9x³ + 7x² - 10x + 2 | 3x + 1

                                                           2x⁵

2)

6x⁶ + 5x⁵ + 2x⁴ - 9x³ + 7x² - 10x + 2 | 3x + 1

-6x⁶ - 2x⁵                                               2x⁵

          3x⁵ + 2x⁴ - 9x³ + 7x² - 10x + 2

3)

6x⁶ + 5x⁵ + 2x⁴ - 9x³ + 7x² - 10x + 2 | 3x + 1

-6x⁶ - 2x⁵                                               2x⁵ + x⁴

          3x⁵ + 2x⁴ - 9x³ + 7x² - 10x + 2

4)

6x⁶ + 5x⁵ + 2x⁴ - 9x³ + 7x² - 10x + 2 | 3x + 1

-6x⁶ - 2x⁵                                               2x⁵ + x⁴

          3x⁵ + 2x⁴ - 9x³ + 7x² - 10x + 2
        - 3x⁵ - x⁴

                 2x⁴ - 9x³ + 7x² - 10x + 2

Since the number of characters to show here is limited, I continue with this division is a separate file.

Please, open the attached pdf file. There you have the entire division.

Remember that if 3x + 1 were a factor the division would be exact. So, since the division is not exact 3x + 1 is not a factor.

Exponential function

Answer from: Quest

9.55 degrees.

step-by-step explanation:

the given angle is $\frac{31\pi}{6}=5.166667\pi$

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
