How many Rhinos will be left 10 years? f left parenthesis t right parenthesis equals P open parentheses 1 plus-or-minus r over n close parentheses to the power of n t end exponent Your answer: 2744 Rhinos 39 Rhinos 2743 Rhinos 40 Rhinos

Answer 1

Answer:

2744 Rhinos will be left after 10 years

Step-by-step explanation:

This question has to do with exponential decay rate. We solve this using the formula:

P(t) = Po(1 - r)^t

Where P(t) = Amount left after t years

Po = Initial amount

r = Decay rate = 3.7% = 0.037

t = time in years = 10 years

P(t) = 4000(1 - 0.037)¹⁰

P(t) = 4000 × 0.963¹⁰

P(t) = 4000 × 0.6859032667003232

P(t) = 2743.6130668

Approximately = 2744 Rhinos will be left after 10 years
