The midpoint of AB is M(7,-5). If the coordinates of A are (6,-7), what are the coordinates of B?
Virty [35]

Answer:

_____________________

a(6,-7) m(7,-5) letb(p,q)

Now,

Let a(6,-7) be x1 ,y1

Let b(p,q) be x2,y2

x,y = (7,-5)

Using Mid point Formula,

x = x1+x2 y= y1+y2

_____ , _____

2 2

7 = 6+p -5 = -7+q

___ , ____

2 2

or, 7×2=6+p , -5×2= -7+q

or, 14=6+p , -10= -7+q

or, p=14-6 , q= -7+10

p=8 , q= 3

Step-by-step explanation:

So , The coordinate of B(8,3)

Thank you

the lateral area of a cone with a diameter of 15 yards is about 287.5 square yards. to the nearest tenth, what is the slant heig
irina1246 [14]
Lateral area of the cone is given by:
LA=πr√(h²+r²)
where:
h=height
r=radius
Given that LA=287.5 yd² and r=(15/2) yds, then the height will be:
287.5=7.5π√(h²+7.5²)
solving for h we get:
(287.5/7.5π)²=h²+7.5²
thus
h²=(287.5/7.5π)²-7.5²
h²=63.1851597
 To get the slant height we use Pythagorean theorem.
c²=a²+b²
a²=h², b²=7.5²
thus
c²=h²+7.5²
c²=63.1851597+56.25
c²=119.4351597
c=10.92864~10.9 yards

I need help!!!!!!!!!!!!!!! 10 points <br><br> Can someone make me not bored. Please
Alexxandr [17]

Here you go

Yeah, when I grow up, you know what I wanna be?

Take a seat, let me tell you my ridiculous dreams

I wanna rap, yeah, I know it's hard to believe

And I can tell you're already thinkin' I will never succeed

But I'm okay with it, I admit the lyrics are weak

I been workin' on 'em, I'll be good eventually

I understand you gotta crawl before you get to your feet

But I been running for a while, they ain't ready for me, ah

I know this probably isn't really realistic

And honestly, I might not ever make a difference

But that don't make a difference, I'ma have to risk it

I been crunchin' numbers, you ain't gotta be a mathematician

To see the odds ain't rootin' for me

I can't lie though, it's kinda how I like it to be

The underdog, yeah, you probably think you know what I mean

But what I'm saying is they ever push me, I'm gonna swing, yeah

I could go to college, get in debt like everybody else

Graduate and probably get a job that doesn't pay the bills

That don't make a lot of sense to me, forget the Happy Meals

I don't like the dollar menu, I would rather make a mil'

Huh? Make a meal? Nah, I said make a mil'

Home-cookin', get the grill, how you want it? Pretty well?

Everything I see is overdone to me, I'm not Adele

But I'ma get a record deal and say hello to mass appeal
