Answer:

The sixth number in series is 13.

Step-by-step explanation:

Given series : 3, -6, 12, 4, 20, ?

The pattern followed by the series is:

The first number = 3

Second number = 3 - 9 = - 6

Third number = - 6 + (9 ×2) = -6 + 18 = 12

Fourth number = 12 - 8 = 4

Fifth number = 4 + (8 ×2) = 20

Sixth number = 20 - 7 = 13

Seventh number = 13 + (7 ×2) = 13 + 14 = 27 and so on.

So as per the above pattern, the sixth number in the series is 13.

Using the distance formula , find the distance from the center of your habitat to the point (x, y). Write this equation. Your an

alexdok [17]

Answer:

See explanation

Step-by-step explanation:

The distance formula is given by:

$d = \sqrt{ {(x_2-x_1)}^{2} + {(y_2-y_1)}^{2} }$

We want to find the distance between (a,b) and (x,y).

The center of the habitat is missing in the question.

Assuming the center is (a,b) where a and b are real numbers, then we can use the distance formula to obtain:

$d = \sqrt{(x - a)^{2} + {(y - b)}^{2} }$

For instance if the center of your habitat us (2,-1), then

$d = \sqrt{(x - 2)^{2} + {(y + 1)}^{2} }$
