Use Newton's method with initial approximation x1 = −2 to find x2, the second approximation to the root of the equation x3 + x +

nevsk [136]

Answer:

$x_2 \approx -1.769$

Step-by-step explanation:

Let $f(x)=x^3+x+7$

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

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

Let $x_1=-2$

We are going to find $x_2$

So we are evaluating $-2-\frac{f(-2)}{f'(-2)}$

First step find f(-2)

Second step find f'(-2)

Third step plug in those values and apply PEMDAS!

$f(-2)=(-2)^3+(-2)+7=-8-2+7=-10+7=-3$

$f'(-2)=3(-2)^2+1=3(4)+1=12+1=13$

$x_2=-2-\frac{-3}{13} \\\\ x_2=\frac{-26+3}{13} \\\\ x_2=\frac{-23}{13} \\\\ x_2 \approx -1.769$

The minute hand of a clock is 1010 inches long and moves from 12 to 33 o'clock. How far does the tip of the minute hand move?

kenny6666 [7]

Answer: 2929 π inch

Step-by-step explanation:

Circumference is given by= 2πr

Here r= 1010 inches

So Tip of minute hand moves= 2π (1010inch)

= 2020 π inch for an hour

Now it comes from 12 to 33 o'clock= 1.45 hour so,

Tip of minute hand moves= 2020 π inch x 1.45

Tip of minute hand moves= 2929 π inch

A tractor trailer weighs 80,000 pounds. Two tractor trailers come upon a bridge with a sign saying it can only handle 100 tons.

NikAS [45]

Two tractor trailers would weigh 160,000 pounds, which is equal to 80 tons. 100-80= 20 tons that are still available.
