Is synthetic division the same as polynomial division?
Elena-2011 [213]

The synthetic division is not same as the polynomial long division.

Given:

Let's take a polynomial function f(x) = x^3+2x^2-5x-6 divided by x-2.

Using synthetic divison:

2    1     2     -5     -6

     0    2      8      6

     1     4      3      0

(x-2)(x^2+4x+3)

= (x-2)(x+3)(x+1)

Polynomial long division:

x-2)x^3+2x^2-5x-6 (x^2+4x+3

     x^3- 2x^2

            4x^2 - 5x + 6

            4x^2 - 8x

                       3x + 6

                       3x - 6

                         0

=(x-2)(x^2+4x+3)

andriy [413]
I'm pretty sure the original price would be $90.75 because 3/4 is .75, so all you have to do is add that to the $90

20 POINTS Find the diameter?? Pls help I dont know what to do..
Akimi4 [234]

Answer:

Diameter = 19.33

Step-by-step explanation:

Imaging a radius line from O to the endpoints of the 7. call this line R.

Label the part of the vertical line from O to the 90 degree intersection y.

Now you have a right triangle.

Using the Pythagorean theorem:

R² = 7² + y²

also

y = R - 3

substitute for y:

R² = 49 + (R-3)²

R² = 49 + R² - 6R + 9

simplify:

0 = 58 - 6R

6R = 58

R = 9.6667

Diameter = 2(9.6667) = 19.33
