A club began with 3 members. Each month, each member brought one new member. Which function can be used to determine the number of members x months after the club began

Step-by-step explanation:

The initial members in the club = 3

⇒ a   =   3

Also, let us assume the needed function is denoted by C(x).

Now, each member brings one new member in the club in 1 month.

So,  the number of members in club after 1 month

= Initial members + Addition of members

=  3 +  3  =  6

or ,

Now, at the starting of second month, initial members = 6

Each member brings 1 new member.

So, the number of new members at the end of second month = 6

Total members at the end of second month = 6+  6 = 12

Continuing the same way, we can see that:

The number of members in club after x months is:

Hence, the needed function is  :

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
