The answer to the question is A
Answer:
a(4) = 15/4
Step-by-step explanation:
Here we're told that the first term is a(1) = 30 and that the common factor r = 1/2.
Thus, the geometric sequence formula specific to this case is
a(n) = 30(1/:2)^(n-1).
What is the fourth term? Let n = 4,
a(4) = 30(1/2)^(4-1), or a(4) = 30(1/2)^(3), or a(4) = 30(1/8) = 30/8, or, in reduced form,
a(4) = 15/4.
6c^2 - c + 1 + 4c - 2c^2 - 8c
= 4c^2 - 5c + 1
= (4c - 1)(c - 1)
Answer:
17=s+7
-7 -7
-----------
10 0
s=10
Step-by-step explanation:
-Subtract 7 from both sides
-Remove the 0 and the addition sign
-You are now left with the equation s = 10
-Once you check to make sure 10 + 7 = 17 you have your answer
Hope this helps :))
