What is the change in elevation from 8,500m to 3,400m

The change in elevation is 5,100 m.

Step-by-step explanation:

Since we have given that

Initial height = 8,500 m

New height = 3,400 m

We need to find the change in elevation:

As we know the change in elevation is the difference between the heights:

So, it becomes,

Hence, the change in elevation is 5,100 m.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
