Answer:
sinΘ = 
Step-by-step explanation:
using the identity
sin²x + cos²x = 1 ( subtract cos²x from both sides )
sin²x = 1 - cos²x ( take square root of both sides )
sinx = ± 
given
cosΘ = - 
, then
sinΘ = ± 
= ± 
= ± 
= ±
since Θ is in quadrant II where sinΘ > 0 , then
sinΘ =
Answer:
You would also need to know for how many hours each day would you be working.
Ok so in order to do this, you have to set up an equation. Let's make a=the score of the first test and b=the score of the second test. (You can choose different variables, it doesn't matter.) It says the sum of the two equals 170. So, a+b=170. It also says that the score of the first was 6 less than the second. This can be shown as a=b-6. Now you can plug this in for a in your original equation. It will look like:
(b-6)+b=170
You can solve for b.
2b-6=170
2b=176
b=88
Since you want a, plug into either equation for b. I'll use the second one.
a=88-6
So, a=82

Step-by-step explanation:
to find % of any number we will devide number by 100 and multiply to which % we want:
12985/100*6=779.1
13764.1/100*6=825.846
908.95/100*6=54.537
14023.8/100*6=841.428
779.1/100*6=46.746
As x → -∞, y → -∞
as x → ∞, y → ∞
