The center of a circle is (0,-6). The radius is 4. What is the equation of the circle? Select all that apply (look at picture)

Step-by-step explanation:

The equation of a circle with center (a,b) and radius r, is given by:

The given circle has centre (0,-6) and radius r=4.

We substitute these values into the formula to get:

This implies that:

When we expand, we get:

The general form is :

step-by-step explanation:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
