With the cossecant, we can find the sine. So:




With the sine, we find the cosine.
Since the tangent is negative, the cosine is negative. So





Cotangent:



Answer:
The answer would be -3.
Step-by-step explanation:
When doing equations like this, you use PEMDAS (Parenthesis, Exponents, Multiply, Divide, Add, Subtract.) . Of course, multiplication is first, so do that left to right, so 24 x 1/4, or .25 . Which ends up as 6. Then divide 6 by -2 you get -3. :)
Answer:
13 or 12.57
Step-by-step explanation:
add all those numbers together and then divide by 7(# of how many numbers there are in that sequence)
Well other ways to represent data in a dot plot would be to convert into a graph or chart. But, for summary, you can take the data and place it in a pie chart to show percentages and increase (or decrease) in the data you took.
