Is the sequence geometric? if so, identify the common. 2, 6, 18, 54,...

To find the common and to see whether the sequence is geometric or not you have to divide n+1 term to n term.

For example 2nd to 1st:
6:2=3
18:6=3

The answer is yes. The sequence is geometric and the common ration is 3. I hope that this is the answer that you were looking for and it has helped you.

What makes a quadratic function unique?

Ilya [14]

Answer:

The graph of a quadratic function is a curve called a parabola which makes a quadratic function unique.

Step-by-step explanation:

Parabolas may open upward or downward and vary in "width" or "steepness", but they all have the same basic "U" shape which makes it easy to identify.

Hope it helps.

The perimeter of a 5 sided figure is 45.56 meters. Two of the sides have the same length. The sum of the other three side length

klio [65]

Let

x---------> the length of the sides that have the same length in meters

we know that

the perimeter of the figure is equal to

$45.56=(24.2+2x)$

<u>solve for x</u>

$2x=45.56-24.2$

$x=21.36/2$

$x=10.68\ m$

therefore

<u>the answer is</u>

Each of the same length side is $10.68\ m$ long

(4,7,12,19) How do you right this in recursive and explicit equations??????? pls help

Soloha48 [4]

You can see how the difference between two consecutive terms is constantly increasing:

$a_1 = 4$

$a_2 = 7 = 4+3$

$a_3 = 12 = 7+5$

$a_4 = 19 = 12+7$

So, for the next terms we'll have to add +9, +11, +13 and so on.

Also, note that $a_2$ is obtained by adding the 2nd odd number to $a_1$ , $a_3$ is obtained by adding the 3rd odd number to $a_2$ , and so on.

So, the recursive formula is

$a_n = a_{n-1}+(2n-1),\quad a_1=1$

For the explicit formula, recall that the sum of the first n odd numbers is n squared. Taking into account the fact that we're not starting from 1, we have

$a_n = n^2+3$

Liz has a 24 inch long ribbon she cuts nine 2 inch pieces from her original ribbon how much of the original ribbon is left?

wel

If she cut off nine pieces of 2-inch ribbon, in all, that would be 18. After that, it would simply be the matter of subtracting 24 and 18.

24 - 18 = 6.

And there's your answer. Liz has 6 inches of ribbon left.
