The only root is -2. The roots are where the function goes through the x-axis. This polynomial goes through in lots of places, but the only answer that matches is -2

Help me please it’s due

Temka [501]

Answer:

13.82 in.

Step-by-step explanation:

To find the circumference of a circle, you multiply the diameter by pi ( $\pi$ ):

$(4.4)(\pi )=13.82301$

Rounded to the nearest tenth, 13.82301 is 13.82. Therefore, 13.82 is the answer.

I hope this helps!

How to calculate the distance for graphs?

ollegr [7]

Answer:

$\sqrt{(x1-x2)^{2}+(y1-y2)^{2} }$

Step-by-step explanation:

This is the distance formula for cartesian coordinate systems, or your typical xy graph. If given two points to find the distance between, you can assign '1' or '2' to the points, i.e. (1,1) and (2,2) could be: (1,1) is (x1,y1) and (2,2) is (x2,y2). It doesn't matter which point is 1 or 2. If we were to use those example points in this formula, we would have:

$\sqrt{(1-2)^{2}+(1-2)^{2}}$

We can simplify and come up with:

$\sqrt{(-1)^{2}+(-1)^{2}}$

= $\sqrt{2}$

We must remember that square roots can be positive OR negative, HOWEVER, because you are looking for a distance it must be positive $\sqrt{2}$ .

Hope this helped!
