Answer:

1. 1,016 sq. m.

2. 119 sq. m.

Step-by-step explanation:

14 x 18 = 252

18 x 8 = 144

14 x 8 = 112

2 ( 252 ) + 2 ( 144 ) + 2 ( 112 )

504 + 288 + 224 = 1,016 sq m

4 (7 x 5 divided by 2) + (7 x 7) =

7 x 5= 35 divided by 2 = 17.5 x 4 = 70 + 49 = 119 sq. m.

I hope this helps

sorry if i'm wrong

Use Newton's method to find the second and third approximation of a root of x3+x+2=0 starting with x1=−1 as the initial approxim

adoni [48]

Answer:

The third approximation is $x_3=-1.08259$

Step-by-step explanation:

We are given that

$f(x)=x^3+x+2=0$

$x_1=-2$

We have to find the second and third approximation of a root of given equation by using Newton's method.

We know that Newton's method , if nth approximation is given $x_n$ and $f'(x_n)\neq 0$ then, the next approximation is given by

$x_{n+1}=x_n-\frac{f(x_n)}{f'(x_n)}$

$f'(x)=3x^2+1$

Substitute $x_1=-2$

$f(x_1)=f(-2)=(-2)^3+(-2)+2=-8$

$f'(x_1)=f'(-2)=3(-2)^2+1=13$

Substitute the value n=1 then, we get

$x_2=x_1-\frac{f(x_1)}{f'(x_1)}$

Substitute the values then , we get the second approximation

$x_2=-2-\frac{-8}{13}=-\frac{18}{13}$

For n=2

$f(x_2)=f(-\frac{18}{13})=(-\frac{18}{13})^3-\frac{18}{13}+2=-2.03914$

$f'(x_2)=f'(-\frac{18}{13})=3(-\frac{18}{13})^2+1=6.75148$

$x_3=x_2-\frac{f(x_2)}{f'(x_2)}$

$x_3=-\frac{18}{13}-\frac{-2.03914}{6.75148}=-1.08259$

Hence, the third approximation is $x_3=-1.08259$
