Answer:
21≤X<28
Or
X≥21+X<28
Step-by-step explanation:
Both equations mean the same thing
Answer:
Step-by-step explanation:
j
The answer would be a-v(2,0),domain: x E R, Range: y E (00,2]
If you plot these points on a coordinate plane, you see that both vertices and foci lie on the y axis. This means that you have a vertical hyperbola, and the equation looks like this:
where h and k are the center. When you look at your graph, the origin is dead center between the vertices. (0, 0) is our h and k. Now we need a, b, and c. a is the distance between the center and the vertices, so our a = 4, and c is the distance between the center and the foci, so our c = 5. Use these in Pythagorean's Theorem to solve for b:
and
and b = 3. So we have all we need to do is replace all the variables. Our equation then would be this one:
or, simplified,
Answer:
C
