Answer: The 3 in 3,899 is 10 times the 3 in 4,385!
Answer:

Step-by-step explanation:





Answer:
- a) p(10) ≈ 48.10
- b) about 1.00 million/year
Step-by-step explanation:
a) Use t=10 in the given formula and do the arithmetic.
39.07×1.021^10 ≈ 48.0951 ≈ 48.10 . . . millions
__
b) The derivative of p(t) is ...
p'(t) = p(t)·ln(1.021) ≈ 0.8120·1.021^t
p'(10) ≈ 0.99954 ≈ 1.00 . . . . millions per year
