Answer:
Step-by-step explanation:
sin38=a/14
a=14(sin38)
a=8.61926
Answer:
a(n) = -3 - 2(n-1)
Step-by-step explanation:
The most general formula for the nth term of an arithmetic sequence (such as this sequence is) is
a(n) = a(1) + c(n-1), where c is the common difference.
Here a(1) = -3 and c = -2.
Thus,
a(n) = -3 - 2(n-1).
2 (6) - 3 (-3) , 12 - -9 , 12 + 9 , 21
I think the answer would be $9.46 left as a tip for the waiter.
