Answer:
a(n)=1.15[a(n-1)]
Step-by-step explanation:
we know that

Let
a0 -----> the length of the original copy
<em>The first copy is equal to</em>
a1=1.15(a0)
<em>The second copy is </em>
a2=1.15[1.15(a0)] or a2=1.15[a1]
<em>The third copy is</em>
a3=1.15{1.15[1.15(a0)]} or a3=1.15[a2]
therefore
A recursive formula will be
a(n)=1.15[a(n-1)]

Answer:
1/12 miles/minute
Step-by-step explanation:
To figure out how fast ellie runs in 1 minute, we can set up this equation:
5/6 = 10x (x being the speed per minute)
We can divide both sides by 10
5/60 = x
Then simplify the fraction to get:
1/12 = x
Answer:
