Answer:
The answers are...:
The common ratio is -3
the sequence of the function is 2,-6, 18, -54, 162
and
the sequence of the function model is geometric
I hope this helps ^^"
Step-by-step explanation:
the common ratio is just from the -3 itself
the sequence model is just plugging n for every term so
a(1) would equal to 2, a(2)=-6 , a(3) would equal to -18, etc
and the geometric is bc it has the exponential that has (n-1), thus it is a geometric sequence
1/36
a 6 on a die is only on one face, so that would be 1/6 of the whole die
to roll a double would mean take 1/6 x 1/6
You number is 40 40 x 2= 80- 16 =64 your welcome :)
