Answer:
d) -4 ≤ x ≤ 1.5
Step-by-step explanation:
The domain is the horizontal extent of the graph. Here, it goes from about x=-4 to about x = 1.5.
There are solid dots on both ends of the line segment, so the inequality will use ≤ for both limits. The domain is ...
-4 ≤ x ≤ 1.5
Answer:
an = 1/2 (4)^ (n-1)
a6 = 512
Step-by-step explanation:
The formula for a geometric sequence is
an = a1 (r)^(n-1)
where an is the term of the sequence
a1 is the initial term of the sequence
r is the ratio
and n is the term number
We know a1 = 1/2 and r =4
I will assume that x=6 means we want to know the 6th term
an = 1/2 (4)^ (n-1)
We want to find the 6th term
a6 = 1/2 * 4^(6-1)
a6 = 1/2 * 4^5
a6 = 512
Multiply 2^(-5) by 2^6. The correct result is 2^1, or just 2 (inches).
Multiply straight across
5/1 * 3/4 = 15/4
now change it into a mixed number
3 3/4
