The ordered pairs are:
<span>{(1, 80), (2, 240), (3, 720), (4, 2160)}
with
a_1 = 80
a_2 = 240
a_3 = 720
a_4 = 2160
The terms are in a geometric sequence with a common ratio of
240/80 = 720/240 = 2160/720 = 3
The equation is:
a_n = 80 * 3^(n - 1)</span>
Answer:
-50y+(-80)
Step-by-step explanation:
You gotta pick number (Miles) that give you higher figure for 0.15 and lower figure 0.10 so that the actual answer comes same after adding them with per day charges.
Let's pick 100 miles for A and B,
A, 0.10x 100 = $10
= ($35 + $10)
=$45
B, 0.15 x 100 = $15
= ($25 + $15)
=$40
Well, it ain't giving us same charge, so we should go higher miles
Let's take 200 miles this time.
A, 0.10x 200 = $20
= ($35 + $20)
=$55
B, 0.15 x 200 = $30
= ($25 + $30)
=$55
Answer: after 200 miles.
Answer:
n = 13
Step-by-step explanation:
The sum of the measures of the interior angles of an n-sided polygon is
(n - 2)180
Set (n - 2)180 equal to 1980 and solve for n.
(n - 2)180 = 1980
Divide both sides by 180.
n - 2 = 11
Add 2 to both sides.
n = 13
