(x-h)^2 + (y-k)^2 = r^2
r=3
(x-h)^2 + (y-k)^2 = 3^2
the center lies on the y-axis --> h=0
x^2 + (y-k)^2 = 3^2 = 9
expand
x^2 + y^2 -2ky + k^2 = 9
x^2 + y^2 -2ky + (k^2 - 9) = 0
compare to general form
A=1 , B=1 and C =0
D= -2k and E=k^2 - 9
Answer:
yes, it is a perfect square trinomial because the square of binomial are (x-0.375) (x-0.375)
Answer:
Your answer would be B
Step-by-step explanation:
a way to remember it is:
- a food web= think of a spiders web and how it goes multiple ways
- a food chain= think of a metal chain, they only link on one another and go only on direction or path
Answer:
The 6th term is first integer value of n greater then 50 in the 2n^2 sequence.
Step-by-step explanation:
2n^2 sequence:
2,8,18,32,50,72
each of the sides of your equation
by the value of
on each of your sides
(you get this because we solve the particular equation we added above)
on each of your sides
because it equals to
because it brings us closer and closer to the answer of
by the number
on each of your sides
