Answer:
is standard equation of hyperbola with vertices at (0, ±9) and foci at (0, ±11).
Step-by-step explanation:
We have given the vertices at (0, ±9) and foci at (0, ±11).
Let (0,±a) = (0,±9) and (0,±c) = (0,±11)
The standard equation of parabola is:
From statement, a = 9
c² = a²+b²
(11)² = (9)²+b²
121-81 = b²
40 = b²
Putting the value of a² and b² in standard equation of parabola, we have
which is the answer.
Answer:
-10, -8, -6, -5, -2, -1
Step-by-step explanation:
I knew this because every negative number can still relate to being the least number. But hey, hope this helps. :]
Answer:
10%
Step-by-step explanation:
In the image attached below, we can see that there are
8 tiles of letter O
2 tiles of letter V
This means that there are 10 total tiles of the letters that you want to get (O and V). Since there are a total of 100 tiles we need to divide this value by 100 to get the probability of getting one of these tiles.
10 / 100 = 0.10 or 10%
Finally, we can see that the probability of selecting a O or a V is 10%
Percent change = (new number - old number)/(old number) * 100
If the percent change is positive, it is a percent increase.
If the percent change is negative, it is a percent decrease.
In our case, the number goes from 500000 (the old number) to 60000 (the new number).
percent change = (new number - old number)/(old number) * 100
percent change = (60000 - 500000)/(500000) * 100
percent change = -88%
Answer: the percent decrease is 88%
Answer:
Multiplying by 1 does not change the ratio
Step-by-step explanation:
Multiplying a/b by c/c gives the equivalent ratio (ac)/(bc) because c/c is 1, the multiplicative identity element. Multiplying by 1 does not change the ratio.
