Step-by-step explanation:
Answer:

Step-by-step explanation:
Since the foci are at(0,±c) = (0,±63) and vertices (0,±a) = (0,±91), the major axis is the y- axis. So, we have the equation in the form (with center at the origin)
.
We find the co-vertices b from b = ±√(a² - c²) where a = 91 and c = 63
b = ±√(a² - c²)
= ±√(91² - 63²)
= ±√(8281 - 3969)
= ±√4312
= ±14√22
So the equation is

Answer:
False
Step-by-step explanation:
6/12 simplifies into 1/2 (six is half of twelve) and 1/2 does not equal 1/3.
You can also plug this into a calculator and see that 6/12=0.5 and 1/3=0.333
