Answer:
0.75
Step-by-step explanation:
300 out of 400 is the same as 3/4.
3/4 converted to a decimal is 0.75.
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

Answer: 0.18 (18 cents) per ounce
Step-by-step explanation:
2.88/16 = 0.18
<u><em>The answer:</em></u> 6x^3+18x
<u><em>The Explanation:</em></u> You need to uses distributive property to 6x to x^2+3 which will be 6x^3+18x
