the vertex form is (x+2)^2 - 9 and the vertex is (-2, -9)
Answer:
1. 1/4
2. 1/2
Step-by-step explanation:
If there are equal numbers of males and females, we can simplify that by saying there's one male and one female for each coat color.
1. What's the probability that both are males?
Well, there's a 1/2 chances the light-colored coat bear is a male and there's also a 1/2 chances the dark-colored coat bear is a male. So, we can make this reference table:
<u>Light Dark</u>
<em>Male Male</em>
Male Female
Female Male
Female Female
As you can see, the probability that both of the spotted bears are males is 1/4 (1/2 * 1/2).
2. If the light-colored bear, what are the odds both are males?
If we know for sure the light-one is male, then there's 1/2 chances the other is too, refer to the table above to verify.
Hello there! :)
4m+2m-m+2m-2m
We can see that 2m-2m cancel out:
4m+2m-m
Now just add all the m's:
6m-m
5m
Hope this helps! :)

Answer:Hint:
the remainder is 2.
Step-by-step explanation:
23≡1 mod 7 and 33≡−1 mod 7.
Edit: The only thing you need from the modular arithmetic is that
a⋅b mod 7=(a mod 7)(b mod 7) mod 7,
meaning the remainder of a product is the remainder of the product of remainders. This is self-evident as a⋅b must have the same remainder as (a−7k)⋅(b−7l).
Since exponentiation is just repeated multiplication, we can write
230⋅320=(23)10⋅(33)6⋅32≡110⋅(−1)6⋅9=9
