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
The equation of a circle:
(h,k) - the coordinates of the centre
r - the radius
Step-by-step explanation:
It is 1 then 2 then 3
Bcz 1 2 5 6 9 10 11 12 13
6 divided by 2 is 3 kilometers.
Therefore, divide 10 by 2 which will get you 5 kilometers.
Sonya can walk 10 kilometers in 5 hours.
