This sequence (1.6, 0.8, 0.4, 0.2,... ) is geometric.
We have formula for any member of geometric sequence:

If a1=1.6 then:

The solution for all these equations is: q=0.5. We have: a1=1.6, q=0.5 and this is geometric sequence.
Answer:
210 ml
Step-by-step explanation:
Faithful representation information that is complete, neutral, and free from error
KE=1/2(m)(v)^2
KE=1/2(80)(1.5)^2
KE=90 J
I'm doing the same thing right now and I'm lost.
