Answer:
16yyyy
Step-by-step explanation:
Getting rid of exponents:
- (-2y)^4 =
- (-2)^4*y^4 =
- 16yyyy
We know that sin2x=2sinxcosx
(search the net for proof if you wish)
So the original equation becomes
2sinxcosx-sinx=0
The two terms both have sinx that can be taken out to get:
sinx(2cosx-1)=0
This is true if sinx=0 or 2cosx-1=0 , rewritten: cosx=1/2
sinx=0 than x=2kπ
cosx=1/2 than x=π/3+2kπ
where k is an integer
√64 = 8
64÷1000 = 0.0064
8÷1000=0.0008
√0.0064 = 0.0008
Answer: 40.2t - 25
Step-by-step explanation:
-0.2t - 5 (-8t + 5)
-0.2t + 40t -25
39.8t - 25
