Use newton's method with initial approximation x1 = 1 to find x2, the second approximation to the root of the equation x4 − x − 2 = 0.

2. use newton's method to approximate the indicated root of the equation correct to six decimal places. the root of x^4 − 2x^3 + 7x^2 − 9 = 0 in the interval [1, 2]

3.suppose the line y = 4x − 1 is tangent to the curve y = f(x) when x = 2. if newton's method is used to locate a root of the equation f(x) = 0 and the initial approximation is x1 = 2, find the second approximation x2.

4. use newton's method with the specified initial approximation x1 to find x3, the third approximation to the root of the given equation. (give your answer to four decimal places.) x^5 + 8 = 0, x1 = −1

5. use newton's method to find all roots of the equation correct to six decimal places. (enter your answers as a comma-separated list.) e^x = 9 − 3x

1. 3/5

2. 1.219841

3. 2 - f(2)/7

4. -1.9682

5. 1.502446

Step-by-step explanation:

1.

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

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.
