Answer:
B
Step-by-step explanation:
We know that
cos A = adjacent / hypotenuse
sin A = opposite / hypotenuse
Therefore, sin A / cos A =
(opposite / hypotenuse) / (adjacent / hypotenuse)
= (opposite/hypotenuse) * (hypotenuse / adjacent)
= opposite / adjacent
= tan A
Therefore, tan A = sin A / cos A = y/x
Step-by-step explanation:
5/2f or 2.5f I think

The recursive formula
can be used to generate the shown sequence
Step-by-step explanation:
Recursive formula is the formula that is used to generate the next term of a sequence using previous term.
The general form of arithmetic sequence's recursive formula is:

Given
5,-1,-7,-13,-19
Here

First of all we have to find the common difference of the sequence.
So,

Putting the value of d in the general recursive formula

Hence,
The recursive formula
can be used to generate the shown sequence
