I'm pretty sure this is correct
The average change of altitude per minute would simply be
the ratio of distance descended over time. That is:
average change of altitude = distance / time
average change of altitude = 0.44 mile / 0.8 minutes
<span>average change of altitude = 0.55 mile / minute</span>
7 is bases number two , I'm not sure it sounds like similar makes more sense , but not sure for 2
The answer of the final sign should be negative
2+sq root of 5
and the sum of zeros = 4
other zero =4-(2+sq root of 5)=2-sq root of 5
