a. write a rule for the sequence using centimeters. The initial height is given by term n = 1
For this case we have a sequence of the form:

Where
a0: initial height
r: rate of change
n: number of paths
On the other hand we have the following conversion:
1 meter = 100 centimeters
Therefore we have:

Thus, the general rule for the sequence in centimeters is:

Answer:
a rule for the sequence using centimeters is:

b. what height will the ball be at the top of the sixth path
For this case, we substitute the value of n = 6 in the equation obtained in part a.
We have then:

Answer:
the height of the ball will be 27.06 at the top of the sixth path
Answer:
3 to 4
or
3:4

Answer:
No they do not have to be congruent.
Step-by-step explanation:
to be a tangent, it would have to have a 90° angle with the radius (12).
and that would make the triangle ABCenter of the circle a right-angled triangle.
and then Pythagoras must apply :
c² = a² + b²
with c being the Hypotenuse (the baseline opposite of the 90° angle). in our case the 20-line.
so,
20² = 12² + 16²
400 = 144 + 256 = 400
yes, it is confirmed, because the Pythagoras principle applies, it is a right-angled triangle, and therefore AB is indeed a tangent.
