The equation of a circle is (x+10)^2+(y-4)^2=100 What is the center and radius of the circle.
1.) Center-10,4); Radius: 10
2.) Center: (-10,4); Radius: 10,000
3.) Center10,-4);Radius: 10
4.) Center10,-4);Radius: 10,000

Answers

Answer:

Correct option is:

1.) Center: (-10,4); Radius: 10

Step-by-step explanation:

The equation of the circle centered at (a,b) and radius r is:

(x-a)^2+(y-b)^2=r^2

Here, we are given a equation:

(x+10)^2+(y-4)^2=100

On comparing this equation with the above equation, we get

a= -10

b=4

and r=10

Hence, Center of circle= (-10,4)

and Radius=10

Hence, Correct option is:

1.) Center: (-10,4); Radius: 10

Hello,

Answer 1
Center=(-10,4)
radius=10

How do you find the volume inside the cylinder but outside the sphere? H=12cm.

Answers

Apparently, there is a sphere inside a cylinder, and we need to find
(the volume of the cylinder) minus (the volume of the sphere).

This wouldn't be too awfully difficult if we had the measurements we need
in order to calculate the volume of the cylinder and the volume of the sphere. 
You did give us a number, thank you, but no description, so we don't even know
what's 12, because we don't know how 'H' figures into anything.

If you have the numbers, here are the formulas you'll need:

Volume of a cylinder = π (radius)² (height or length)

Volume of a sphere = (4/3) π (radius)³
===============================================
Oh I think I get it.  There's a little ball stuck inside a cylinder, they
both have the same radius, and the height of the cylinder is 12.

That's still not enough information to do a complete calculation.
I'm afraid we still need that radius.  But we can get closer:

Volume of the cylinder = π (radius)² (12)

Volume of the sphere = (4/3) π (radius)³

(Cylinder) minus (sphere) = (4/3) π (radius²) ( 9 - radius ) .

Stuff the number for the radius into that, and you'll have the answer.

And if you need it, remember, the radius is 1/2 of the diameter.

When graphing an inequality how do you know whether the line should be solid or dotted? plz go into detail and if you have a specific way your remember it plz help i need it for my final exam.

Answers

well, when it comes to graphing an inequality, and you need to know whether the line is solid or dashed, look at the inequality sign.....   (i do not remember that exact terms)  anyway, if it is JUST > or < then it is dashed, that is because you are not including that number, just any number greater than or less than it...

however, if it is Greater than or Equal to 
or
less than or equal to
where these two are including that # by having the "or equal to", it will be solid for it is INCLUDING what ever # we are using...

for example

y > 3 will be dashed

where as     y is greater than or equal to 3 will be solid since the y could be 3

i cant really explain this well...   but i hope i made it somewhat clear
