Answer:
C) 3,-2,-7,-12
Step-by-step explanation:
A sequence is defined recursively using the formula f(n+1)=f(n)-5. Therefore, 3,-2,-7,-12 is the sequence that could be generated using this formula.
Answer:

Step-by-step explanation:
The given angle is 240 degrees.
We need to find the exact value of each trigonometric function for the given angle θ.
Since
, it means θ lies in 3rd quadrant. In 3d quadrant only tan and cot are positive.






Therefore, 
Answer:
1/2.
Step-by-step explanation:
There are 2 quadrilaterals which have 4 congruent sides in the list: A square and a rhombus, The square is the one with four right angles.
So the required probability is 1/2.
