Answer:
Option A. is the correct option.
Step-by-step explanation:
We have to get the simplified form of sin (.6x)-sin(.4x)
As we know the identity sinA- sinB = 2 cos(A+B)/2.sin(A-B)/2
We apply the identity in the given expression
sin(.6x)-sin(.4x) = 2 cos(.6x + .4x)/2.sin(.6x - .4x)/2
= 2 cos(x/2).sin(0.2x/2) = 2 cos(0.5x).sin(0.1x)
Therefore option A is the correct option.
Answer:
Step-by-step explanation:
12/(x+2) = 4/(x-2)
Cross-multiply to get:
12x-24 = 4x+8
8x = 32
x = 4
111=100(1.0153)^x
Solve for x
X=log(111÷100)÷log(1.0153)
X=6.9years round the answer
X=7 years
So in what year
2000+7=2007
In the year 2007
