Step-by-step explanation:
Answer:
x^2 + y^2 = 4
Step-by-step explanation:
The center-radius form (formally called the standard form) of a circle is
(x-h)^2+(y-k)^2=r^2 where (h,k) is the center and r is the radius.
So if we replace (h,k) with (0,0) since the center is the origin and r with 2 since the radius is 2 we get:
(x-0)^2+(y-0)^2=2^2
Let's simplify:
x^2 + y^2 = 4
Answer:
65
Step-by-step explanation:
median = (N+1)/2
=(100+1)/2
= 50.5
cf just greater than 50.5 is 65 .So, median is 65.
Answer:
Step-by-step explanation:
2y + 1 is a binomial, in that it has two terms.
If we set 2y + 1 equal to x, then 2y = x - 1, or
x - 1
y = -----------
