Answer:
1.FP = Future population ⇒ unknown
PP = Present population ⇒ 1,000
r = growth rate ⇒ 200% or 2.00
time = 10/60
FP = PP (r) ^{t}FP=PP(r)
t
FP = 1,000 × (2) ¹/⁶ ⇒ exponential model
FP = 1,000 × (1.12246...)
FP ≈ 1,122.46 or 1,123 ⇒ barangay population in 10 years

Answer:
a. y=100(1/2)ᵗ/²⁵⁰
b. 25g
Step-by-step explanation:
b. y=100(1/2)ᵗ/²⁵⁰
= 100(1/2)⁵⁰⁰/²⁵⁰
=100(1/2)²
=100(0.25)
=25g (the amount that will remain after 500 years)
edit:
at t=0 amount of substance:100g
at t=250 amount of substance:50g
at t=500 amount of substance: 25g
Step-by-step explanation:
hope it's help
