Answer:
B
Step-by-step explanation:
Well since it is arthimetic sequence we know the formula
We know d is difference between second term and first so it will be -5- (-12)= -5+12= 7

the domain of this is 1,2,3,4.......
range is -12,-5,2,9.......
Therefore answer is B.
6/8 simplifies to 3/4.
Divide both numbers by 2 and you can then simplify.
13 because 8 is bigger than 5 so that 9 becomes a 0 and the 0s don't mean anything
The answer will be 18.6 degrees.
