Answer:
Either
(approximately
) or
(approximately
.)
Step-by-step explanation:
Let
denote the first term of this geometric series, and let
denote the common ratio of this geometric series.
The first five terms of this series would be:
First equation:
.
Second equation:
.
Rewrite and simplify the first equation.
.
Therefore, the first equation becomes:
..
Similarly, rewrite and simplify the second equation:
.
Therefore, the second equation becomes:
.
Take the quotient between these two equations:
.
Simplify and solve for
:
.
.
Either
or
.
Assume that
. Substitute back to either of the two original equations to show that
.
Calculate the sum of the first five terms:
.

Please give me brainliest, I would appreciate it!
Answer:
for every 1000 people, the maximum noise level goes up by 1.5
The equation of a straight line would be y=mx+c,
where,
m=slope and c=y-intercept
You multiply 580 by 6.5%
The interest he will get rounded $38.00
