G(x) = x3 + 6x2 + 12x + 8Determine the function’s value when x = −1.
Aneli [31]
Plug in  -1 for x and  work it ou'

g(-1) = (-1)^3 + 6(-1)^2 + 12(-1) + 8

= -1 + 6 - 12 + 8

=  1

HURRY! One of the roots of the equation <img src="https://tex.z-dn.net/?f=5x%5E%7B2%7D%20-12x%2Bc%3D0" id="TexFormula1" title="5
kotegsom [21]

Answer:

<em>c = 4</em>

Step-by-step explanation:

x + 5x = 12/5

30x = 12

x_{1} = 2/5

x_{2} = 2

<em>c </em>= [(2/5)*2] * 5 =<em> 4</em>

(5x - 2)(x - 2) = 0

5x² - 12x + 4 = 0

3x^2+x-5=0 to 2 decimal place<br> 3x^3+2x-4=0 to 2 decimal place
Schach [20]

Answer:

1. 3/5

2. 1.219841

3. 2 - f(2)/7

4. -1.9682

5. 1.502446

Step-by-step explanation:

If we call

then the second approximation to the root of the equation f(x)=0 would be

hence

2.

Here we have

Let's start with  

then

Since the first 6 decimals of  and  are equal, the desired approximation is 1.219841

3.

If the line y = 4x − 1 is tangent to the curve y = f(x) when x = 2, then f'(2) = 4*2 - 1 = 7, so

4.

Here

5.

We want to find all the values x such that

or what is the same, the x such that

so, let f(x) be

and let's use Newton's method to find the roots of f(x).

Since

f is strictly increasing, and since

f(1) = e+3-9 = e - 6 < 0

and

f has only one root in [1,2]

By using Newton's iterations starting with  

Since  then

x=1.50244564 is the desired root.

The answers as a comma-separated list would be

1,  1.573899431,  1.503982961,  1.502446348, 1.50244564

The answer rounded to six decimal places would be

1.502446
