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:
Drew studied for an hour for 4 days in a row. How many hours did he study? Drew studies for 2.5 hours.
Step-by-step explanation:
The model shows that drew studied 2/8 every day and 2/8 is equal to 1/4 cut all five days that he studied in half and you get 2.5.
Answer:
Step-by-step explanation:
If c = 8, then:
5c^(3)+982 => 5(8)^3 + 982 = 3542
and
2c^(4)−7c = c(2c^3 - 7) => 8(2*512 - 7) = 8(1017) = 8136
So the second expression has the greater value when c = 8.
