Answer:
67
Step-by-step explanation:
you square it then you divide do the algebratic forumula and then times agian divide take away from the 3m
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>
I would say It’s answer C
Answer:
b ≈ 13.7
Step-by-step explanation:
use the panthagrean thereom
a^2 + b^2 = c^2
10^2 + b^2 = 17^2
100 + b^2 = 289
<u>-100 -100</u>
b^2 = 189
√b^2 = √189
b = 13.74772708486752
b ≈ 13.7
