First let's isolate the sin(x) term
4sin(x) - 4 = 0
4sin(x) = 4
sin(x) = 1
Now use the unit circle and you'll see that the only solution in the interval [0,2pi) is x = pi/2
If you want to ignore the restriction and consider all solutions, then x = (pi/2) + 2pi*n where n is any integer
I got 140-210 =-50
So
50 B
And 76
60/150*350 for a red bottles
Minus 120/200*350 for b to get answer 1
110/175*350-72/180*350 for answer 2
Step-by-step explanation:
A140
B210
C220
D144
There is no sum for this geometric series. it diverges rather than converges due to the absolute value of the common ratio (r), which is -3, being 3. for a geometric series to have a sum (to converge), the absolute value of r must be less than 1.
(you find r by dividing a2/a1, a3/a2, etc.)
hope this helps
