Which circles have inscribe angles

1 & 3

Step-by-step explanation:

Inscribed angles are angles formed in the interior of a circle.                                  There isn't really anything to explain because the angle formed by two chords or secants that meet at a point at the edge of a circle.

Step-by-step explanation:

Table representing the station number (x-coordinates) and time to complete the task (y-coordinate) is,

x         1           2           3           4

y         4          8          16          32

a). Ratio of second term to the first term of 'y' =

    Ratio of 3rd and 2nd term =

    There is a common ratio 'r' = 2

    Therefore, this data model a geometric sequence.

b). Recursive formula of a geometric sequence is represented by,

    nth term

      Previous term of the nth term

    Therefore, recursive formula for the given data will be,

c). Explicit formula of a geometric sequence is given by,

   Here, a = First term

   r = common ratio

   n = number of term

    nth term

   Explicit formula for the given sequence will be,
