What is an expression for the area of the shaded region? Simplify your answer.
Reptile [31]

Answer:

if it is put into a equation this would be it

2(x^2+6x+9) - (1.57)(x^2+6x+9)

Step-by-step explanation:

(x+3)(2x+6) - 1/2(3.14)(x+3)(x+3)

(2x^2+6x+6x+18) - 1/2(3.14)(x^2+3x+3x+9)

(2x^2+12x+18) - 1/2(3.14)(x^2+6x+9)

2(x^2+6x+9) - (1.57)(x^2+6x+9)

2(x^2+6x+9) is the rectangle at the bottom

(1.57)(x^2+6x+9) is the semicircle that is taking out of the shaded area

Genber wiil evaluate an 8th degree polynomial in x at x=10 using the remainder theorem and synthetic division.how many coefficie
lisabon 2012 [21]
An 8th-degree polynomial needs 9 terms that involve
 x⁸, x⁷, ..., x¹, and x⁰.

x=10 implies that (x-10) is a factor of the polynomial according to the Remainder theorem.

Let the polynomial be of the form
f(x) = a₁x⁸ + a₂x⁷ + a₃x⁶ +a₄x⁵ + a₅x⁴ + a₆x³ + a₇x² + a₈x + a₉

The first few lines of the synthetic division are

10 | a₁  a₂  a₃  a₄  a₅  a₆  a₇  a₈  a₉             ( the first row has 9  coefficients)

    -----------------------------------------
      a₁

Answer:
The first row has 9  coefficients.

What is the x-intercept of y=5x+20?
densk [106]

Answer:

the x intercept is -4

Step-by-step explanation:

to find the x intercept, set y = 0 and solve for x

y = 5x+20

0 = 5x+20

subtract 20 from each side

-20 = 5x +20 -20

-20 = 5x

divide each side by 5

-20/5 = 5x/5

-4 =x
