It would be a triangle, because a triangle has 3 equal sides

I hope this helps

Calculate two iterations of Newton's Method for the function using the given initial guess. (Round your answers to four decimal

pickupchik [31]

Answer:

The first and second iteration of Newton's Method are 3 and $\frac{11}{6}$ .

Step-by-step explanation:

The Newton's Method is a multi-step numerical method for continuous diffentiable function of the form $f(x) = 0$ based on the following formula:

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

Where:

$x_{i}$ - i-th Approximation, dimensionless.

$x_{i+1}$ - (i+1)-th Approximation, dimensionless.

$f(x_{i})$ - Function evaluated at i-th Approximation, dimensionless.

$f'(x_{i})$ - First derivative evaluated at (i+1)-th Approximation, dimensionless.

Let be $f(x) = x^{2}-8$ and $f'(x) = 2\cdot x$ , the resultant expression is:

$x_{i+1} = x_{i} -\frac{x_{i}^{2}-8}{2\cdot x_{i}}$

First iteration: ( $x_{1} = 2$ )

$x_{2} = 2-\frac{2^{2}-8}{2\cdot (2)}$

$x_{2} = 2 + \frac{4}{4}$

$x_{2} = 3$

Second iteration: ( $x_{2} = 3$ )

$x_{3} = 3-\frac{3^{2}-8}{2\cdot (3)}$

$x_{3} = 2 - \frac{1}{6}$

$x_{3} = \frac{11}{6}$

Hi! Can you help me answer this?

Free_Kalibri [48]

Answer:

$C'(x)=-\frac{148}{x^2}$

$R'(x)=-0.06$

Step-by-step explanation:

Marginal average Cost function:

$\frac{d}{dx}(\frac{148+6.3x}{x})=-\frac{148}{x^2}$

Marginal average Revenue function:

$\frac{d}{dx}(\frac{3x-0.06x}{x})=-0.06$

Trey is putting up fence around a 750 foot by 540 foot lot. How many feet of fence does he need?

muminat

Answer:

2580 feet

Step-by-step explanation:

The question is essentially asking for the perimeter.

Considering the lot is a parallelogram at the least, it would be (750+540)*2, or 1290*2, or 2580
