Sequence: 2, 6, 18, 54, 162,
Required
Determine the 15th term
The above sequence is a geometric sequence. So, first, we calculate the common ratio (r)
The 15th term is calculated as thus:
Where
and
<em>The 15th term is 9,565,938</em>
Answer:
The vertex and the axis of symmetry in the attached figure
Step-by-step explanation:
we know that
The equation of a vertical parabola written in vertex form is equal to
where
a is the leading coefficient
(h,k) is the vertex of the parabola
and the equation of the axis of symmetry is equal to the x-coordinate of the vertex
In this problem
we have
This is a vertical parabola written in vertex form open upward
The vertex is a minimum
where
the vertex is the point (5,-7)
the x-coordinate of the vertex is 5
so
the equation of the axis of symmetry is equal to
The graph in the attached figure
