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

Hi Cherise1cherhop lets break this equation down with these steps:
1) add the whole numbers first
2) find the LCD of the fractions and that would be 42 since 42 can go into both denominators through multiplication
3) make the denominators (bottom numbers) the same as the LCD (42)
4) simplify it, now the denominators are equal
5) join the denominators together
6) simplify it (3 + 65/42)
7) convert 65/42 to mixed fraction
8) now that we made it a mixed fraction, simplify it
Answer: 4 23/42
Answer:
The answer to your question is: I bought 7 snacks
Step-by-step explanation:
Data
beginning balance = $42 = b
lunch = $1.80 = l
snack = $ 0.85 = s
final balance = $0.05 = f
f = b - 1.8l - 0.05s
0.05 = 42 - 1.8l - 0.85s
After 20 days I spent = 1.8(20) in lunches = $36
0.05 = 42 - 36 - 0.85s
0.05 = 6 - 0.85s
0.05 - 6 = -0.85s
-5.95 = -0.85s
s = -5.95/-0.85
s = 7
The answer as a fraction is 6/11
