Answer:
The bacteria will grow from 1 to 1024 in 10 hours
Step-by-step explanation:
Given
P_0 = 1
P = 1024
We have to find time
Putting values in the formula

Anything multiplied with 1 remains the same

Using the property "when bases are same, the exponents can be put equivalent"
t = 10 hours
Therefore, the bacteria will grow from 1 to 1024 in 10 hours ..
He started at 418 above sea level. descended means he moved down so subtract 88 from 418:
418 - 88 = 330 feet.
He then climbed 120, so now add that to the 330:
330 + 120 = 450
He is now at 450 feet above sea level.
