Answer:
they are vertical angles
Step-by-step explanation:
just learned about this
If the endpoints of a diameter are (6,3) and (2,1) the midpoint is the center of the circle so:
(x,y)=((6+2)/2, (3+1)/2)=(4,2)
Now we need to find the radius....the diameter is:
d^2=(6-2)^2+(3-1)^2
d^2=16+4
d^2=20 since d=2r, r=d/2, and r^2=d^2/4 so
r^2=5
The standard form of the circle is (x-h)^2+(y-k)^2=r^2 and we know:
(h,k)=(4,2) from earlier so:
(x-4)^2+(y-2)^2=5
If you would like to calculate <span>10÷5/8, you can do this using the following steps:
</span><span>10÷5/8 = (10/5)/8 = 2/8 = 1/4 = 0.25
The correct result would be 1/4 or 0.25.</span>
Answer:
11, 44, 24
Step-by-step explanation:
On the right side column you are adding 11 every time you add 4 on the left side column
For example :
4:11
8:22
12:33
16:44
20:55
24:66
Hope this helps!!! :)))
I'm not sure what you're asking but if you're looking for simplification, here it is. -7x² + 2x - 12
