Answer:ot would be 8000
Step-by-step explanation:
I am assuming you want to solve for x:-
Now cosec^2 2x = 1 - cot^2 2x so the equation becomes
3 cosec^2(2x) + 2 cosec 2x = cosec^2 2x
2 cosec^2 2x + 2 cosec 2x = 0
2 cosec 2x ( cosec 2x + 1) = 0
so 2 cosec 2x = 0 or cosec 2x = -1
cosec 2x = 0 or cosec 2x = -1
cosec 2x = 0 is indeterminate so we ignore the first one
cosec 2x = -1 can be written as 1 / sin 2x = -1
so sin 2x = -1
giving 2x = 270 degrees
Therefore x = 135 degrees answer

Answer:
D=160-13 1/3t
Step-by-step explanation:
D is distance in this instance
We are using y=mx+b for this.
The initial distance is 160 miles, that's our y-intercept or <em>b</em><em>.</em>
Now we need to find our slope. If Andrew is 40 miles away in 3 hours, he is 13 and 1/3 miles away in 1 hour. It's negative because you are subtracting from the initial distance. You can keep that as an improper fraction if that makes it easier for you.
Now plug it in
Distance=13 1/3 miles times <em>how</em><em> </em><em>many</em><em> </em><em>hours</em><em> </em>subtracted from 160 or D=-13 1/3+160. This can be rearranged to the answer above.
