The length of ab is D. 15
Answer: 1211.6585 years
<u>Step-by-step explanation:</u>
The equation for exponential growth is: 
- P: final population
- P₀: initial population
- k: rate of decay (or growth)
- t: time
Use the half life information to find k:

Next, input the information (65% decayed = 35% remaining) and the k-value to find your answer.

Answer:
10 pushups?
or 20 if you do 10 pushups per day.
that would be an extra 24 calories burned (12 each day), depending on how fit you are, and not nearly enough pushups to be of any help to your physical health.
