Answer: C
Step-by-step explanation:
For this problem, we need to know the standard form of a sine function and the meaning of each part.
Standard form: ![y=asin[b(x-h)]+k](https://tex.z-dn.net/?f=y%3Dasin%5Bb%28x-h%29%5D%2Bk)
a=amplitude
b=period
h=phase shift
k=vertical replacement/shifting
Now that we know the standard form and the components, we know that we can forget about k and plug in 0 for h. This would leave us with
. We know that the amplitude is 2, therefore, a=2. To find the period, you divide 2π by the given period.
, therefore, b=1/2.
[plug in a=2]
[plug in b=1/2]

Therefore, C is the correct answer.
8^2= 8 times 8 = 64
8^4= 8 times 8 times 8 times 8= 4,096
Answer:
where is this from
Step-by-step explanation:
The answer is 2 .
simplify log(down)10 (1/100) : -2
apply log rule : -log(down)10 (100)
rewrite 100 in power-base form : -log(down)10 (10^2)
apply log rule again : -2log(down)10 (10)
apply one more time : -2*1
Multiply : -2
refine from -(-2) = 2
I hope this helps
(-4,-1) because -1 × 4= -4 and -4=y
