Answer:
Radius=4 units
Centre= (0,-10)
Step-by-step explanation:
Given equation of circle is x^2 +(y-10)^2=16
Comparing it with (x-h)^2 +(y-k)^2 = r^2 ,we get,
r=4
Since, centre of a circle=(h,k)=(0,-10)
Answer:
no, I don't like quarantine.
x should be 115 because it is parallel to the one above. each line should equal 180. So 180-115= 65
y=65
well, to do this we first need to find the mean of all values.
we need to find the distance of each value from that mean (subtract the mean from each value, ignore minus signs)
Then find the mean of those distances.
so, after we do all of that with the given numbers, our final result would be 2.333333333..... (It goes on) we round it up to 2.3, and viola! the answer is C.
I will help the answer is 55 b
First, to be able to compare these two things, you have to either find the radius of Mercury or find the diameter of the moon. I choose finding the diameter of the moon because it seems easier.
Diameter=radius*2
Diameter=1736.5*2=3473
The moon has a diameter of 3473 km.
Since Mercury's diameter, 4878km, is greater than the Moon's diameter, 3473km, Mercury is larger.
Hope this helps!
