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.

Answer:
(-1,-1)
Step-by-step explanation:
If you multiply the x and y points of A, (-3,-3), by 1/3 then you find: (-1,-1).
x + 2x - x - 1
- Substitute 2 for x into the expression.
(2) + 2(2) - (2) - 1
(2) + (4) - (2) - 1
- Solve from left to right.
- (2 + 4) - 2 - 1 = 6 - 2 - 1
6 - 2 - 1
- Solve from left to right.
- (6 - 2) - 1 = 4 - 1
4 - 1 = 3
<h3>Your answer is 3.</h3>
