Answer:
<h3>The 12th term is 1771470</h3>Step-by-step explanation:
Since the above sequence is a geometric sequence
An nth term of a geometric sequence is given by
where a is the first term
r is the common ratio
n is the number of terms
From the question
a = 10
To find the common ratio divide the previous term by the next term
That's
r = 30/10 = 3 or 90/30 = 3 or 270/90 = 3
Since we are finding the 12th term
n = 12
So the 12th term is

Answer:
a. .
b. The axis of symmetry for is
.
Step-by-step explanation:
a. The vertex form of a quadratic is given by , where (h, k) is the vertex.
To convert from form to vertex form you use the process of completing the square.
Step 1: Write in the form
. Add and subtract 4:
Step 2: Complete the square
b. The graph of a quadratic function is a parabola. The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola. The x-coordinate of the vertex is the equation of the axis of symmetry of the parabola.
For a quadratic function in standard form, , the axis of symmetry is
.
The axis of symmetry for is
.
Look at the graph shown below.
