A is the best answer…
Work:
-10x-(-4y) will equal -10x+4y the minus minus will cancel out
Please like and brainiest
4 years = 48 months = 8 6 month increments so it doubles 8 times
0 5
1 10
2 20
3 40
4 80
5 160
6 320
7 640
8 1280 rabbits
Scientific notatino is
(number that is greater than or equal to 1 and less than 10) times (10^x)
so
318.9
we need to make it less than 10
move decimal 2 places to left
3.189
to make it the same number, we multipl it by 10^2 to make it go back
scientific is
3.189 times 10^2
Answer:
68°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relation between the angle's adjacent side and the hypotenuse is ...
Cos = Adjacent/Hypotenuse
This means ...
cos(B) = a/c
B = arccos(1/√7) ≈ 68°
