Answer:

The solution to the quadratic equation x² - 4x - 2 =0 is 0.59 and 3.41

Step-by-step explanation:

Given the equation -2x² - 4 = -8x

rearrange the equation we now have -2x² +8x - 4 = 0

divide each term in the equation by -2, we have

x² - 4x - 2 =0

To get the table, we substitute the given values of x in the equation to get the corresponding values for y

x values     y values

0.59            -0.0119

3.41              -0.0119

-3.41              27.2681

-0.59            4.7081

1.17                -1.3111

6.83             21.3289

-1.41              9.6281

1.41               -1.6519

The two points of x where y =0 are 0.59 and 3.41

Therefore the solution to the quadratic equation x² - 4x - 2 =0 is 0.59 and 3.41

Class be boring but anyways what is ( 2 x 2 − 1 )?
mina [271]

Answer:

3

Step-by-step explanation:

In order to do this equation, your first step is to use the Order of Operations, or PEMDAS, which means that you multiply (M) two times two first before subtracting the equation (S). 2 times 2 is 4.  4 - 1 = 3. Hope I helped! :)

What is the average rate of change of the function f(x)=20(14)xf(x)=20(14)x from x = 1 to x = 2? Enter your answer, as a decimal
Advocard [28]
The average rate of a function f(x) over an interval x = a and x = b is given by:

Average \ Rate \ of \ Change= \frac{f(b)-f(a)}{b-a}

Given the function

f(x)=20(14)^x

The average rate of change from x = 1 to x = 2 is given by:

\frac{f(2)-f(1)}{2-1} = \frac{20(14)^2-20(14)^1}{1}  \\  \\ =20(196-14)=20(182)=3,640
