F=3/5x^2-3x+18/5 is the answers
Answer:
third option
Step-by-step explanation:
The n th term of a geometric sequence is
= a₁ 
where a₁ is the first term and r the common ratio
← is in this form
with a₁ =
and r = 2
A.) P(t) = 130t - 0.4t^4 + 1200
The population is maximum when P'(t) = 0
P'(t) = 130 - 1.6t^3 = 0
1.6t^3 = 130
t^3 = 81.25
t = ∛81.25 = 4.3 months.
Maximum population P(t)max = 130(4.3) - 0.4(4.3)^4 + 1200 = 1,622
b.) The rabbit population will disappear when P(t) = 0
P(t) = 130t - 0.4t^4 + 1200 = 0
t ≈ 8.7 months
Simple interests will only take into account the principle, but compound interest adds money to interest earned AND the principle.
