Answer:
The n-th term of this sequence appears to be
3
n
−
1
,
n
≥
1
.
Step-by-step explanation:
These are powers of
3
ordered from
3
0
=
1
to
3
a
(for an integer
a
≥
1
). However, the first convenient value for
n
is
1
, not
0
(imagine saying the 0th term of a sequence). Because of that, since the first term is actually
3
0
, we need to start from the first term (
n
=
1
) being
3
1
−
1
. The next is
3
2
−
1
,
3
3
−
1
...
3
n
−
1
.
For this case we have the following equation:
12x2-5x-2 = 0
Using the resolver we have:
x = (- b +/- root (b ^ 2 - 4 * a * c)) / (2 * a)
Substituting values we have:
x = (- (- 5) +/- root ((- 5) ^ 2 - 4 * 12 * (- 2))) / (2 * 12)
Rewriting:
x = (5 +/- root (25 +96))) / (2 * 12)
x = (5 +/- root (121))) / (2 * 12)
x = (5 +/- 11) / (2 * 12)
Answer:
One root is positive and another is negative.
Answer:
Adult tickets=275
Step-by-step explanation:
form 2 equations from the given info.
x+y=611
y=x+61
x being the adults and y being the students tickets
then substitute the y equation into the first equation.
x+x+61=611
2x+61=611
2x=550
x=275
and you can check by putting 275 back into the original equations :)
Answer:
look at the picture i sent plz......
I think its A because a and b are not the same answer and a is the correct one i think
