Answer:

If all possible vertical lines will only cross the relation in one place, then the relation is a function. This works because if a vertical line crosses a relation in more than one place it means that there must be two y values corresponding to one x value in that relation.

Step-by-step explanation:

<u>Volume Of A Pyramid </u>

The volume of a pyramid is computed as one third of the product of the area of the base (B) by the height (H):

$\displaystyle V=\frac{1}{3}BH$

<em>The question doesn't ask for anything in particular, so I'm computing the volume of the solid shown in the image </em>

We have a rectangular base of dimensions 15m x 60 m. The area of the base is

$B=(15m)(60m)=900m^2$

We now calculate the volume, knowing the height is 55 m

$\displaystyle V=\frac{1}{3}(900\ m^2)(55\ m)$

$\boxed{\displaystyle V=16500\ m^3}$

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!

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

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

So

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