The standard form for the equation of a circle is :
<span><span><span> (x−h)^</span>2</span>+<span><span>(y−k)^</span>2</span>=<span>r2</span></span><span> ----------- EQ(1)
</span><span> where </span><span>handk</span><span> are the </span><span>x and y</span><span> coordinates of the center of the circle and </span>r<span> is the radius.
</span> The center of the circle is the midpoint of the diameter.
So the midpoint of the diameter with endpoints at (−10,1)and(−8,5) is :
((−10+(−8))/2,(1+5)/2)=(−9,3)
So the point (−9,3) is the center of the circle.
Now, use the distance formula to find the radius of the circle:
r^2=(−10−(−9))^2+(1−3)^2=1+4=5
⇒r=√5
Subtituting h=−9, k=3 and r=√5 into EQ(1) gives :
(x+9)^2+(y−3)^2=5
Answer:
Already Rounded (6,000,000)
Step-by-step explanation:
- Locate the thousands spot.
6,00<u>0</u>,000
2. Check next door.
The hundreds place has a zero digit. Since zero is less than 5, we round down.
Since 6,000,000 rounded to the nearest thousand is the same number, we can say that it's already rounded.

Cos 52 = 0.6157
sin 42 = cos 48 = 2/3 (because 42 + 38 = 90 - complementary angles)
if tan 20,5 = 3/8 then tan 69.5 wil = 1 / 3/8 = 8/3
I believe the ray opposite of DE is DA.
Hope this helps, and don't worry, I'm sure you won't fail!
Answer:
19x-1/3
Step-by-step explanation:
it is the right answer we have to take lcm for this by taking only lcm we can solve it..
