Anna007 [38]3 years ago

Answer:

- 6

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [ a, b ] = [ - 1, 4 ] , then

f(b) = f(4) = 4³ - 6(4)² - 4 = 64 - 96 - 4 = - 36

f(a) = f(- 1) = (- 1)³ - 6(- 1)² - (- 1) = - 1 - 6 + 1 = - 6 , then

average rate of change = \frac{-36-(-6)}{4-(-1)} = \frac{-36+6}{4+1} = \frac{-30}{5} = - 6

The answer to the polynomial
MariettaO [177]
-Polynomials don't have answers.
This question just wants you to add 2 polynomials.
The pencil work under the first one is incorrect.

Here's what you need to do to find the sum of polynomials:

-- Remove parentheses.
(If there's a plus sign before the whole parentheses, then just erase the parentheses.  If there's a minus sign before the whole thing, then change the sign of each term inside, and erase the parentheses.)

-- Add up all the  x² terms.
 Like this ...

             x² + x² = 2x²
or
          2x² + 7x²  =  9x²

-- Add up all the x³ terms the same way.

-- Add up all the 'x' terms the same way.

-- Add up the plain numbers.

-- Write down all the sums as a new polynomial.

Quadrilateral ABCD is inscribed in circle 0 What is m<A
valentinak56 [21]
We know that
 A quadrilateral is inscribed in a circle if and only if the opposite angles are supplementary. ( Inscribed Quadrilateral Theorem)
so
m∠B+m∠D=180°
2x+(3x-5)=180
5x=180+5
5x=185
x=185/5
x=37°

m∠A=x+5-----> 37+5------> 42°

the answer is
m∠A is 42°

i When 20 is added to a certain number and the sun is divided by 3, the result is 3 times the number, find the number.​
Bingel [31]

Answer:

let \: the \: number \: be \: x \\  \frac{20 + x}{3}  = 3x \\  \frac{3(20 + x)}{3}  = (3x)3 \\ 20 + x = 9x \\ 20 = 9x - x \\ 20 = 8x \\  \frac{20}{8}  =  \frac{8x}{8}   \\ x = 2.5

Step-by-step explanation:

Hope that this is helpful .

Have a great day.
