Answer:

vertex = (0, 1 )

Step-by-step explanation:

f(x) = 9x² + 1 ← has it's vertex on the y- axis

let x = 0 in f(x)

f(0) = 9(0)² + 1 = 0 + 1 = 1

vertex = (0, 1 )

Find an explicit formula for the geometric sequence -40,-20,-10......

garik1379 [7]

Answer:

The explicit formula for the geometric sequence is $c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}$ .

Step-by-step explanation:

By definition of geometric sequence, we should use the following expression:

$c(n) = c_{1}\cdot r^{n-1}$ , $n \ge 1$ (1)

Where:

$c_{1}$ - First term.

$r$ - Geometric rate.

$n$ - Position of the element within the series.

If we know that $c_{1} = -40$ and $r = \frac{1}{2}$ , then the explicit formula for the geometric sequence is:

$c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}$

The explicit formula for the geometric sequence is $c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}$ .
