Answer: ______________
5. A tank holds 60 L and gains 8 L per minute. Write V(t).
Work
Answer: ______________
6. A population of 20 doubles (×3) every year. Write P(t).
Work
Answer: ______________
Answer key: 1) V(t) = 70 + 9t · 2) P(t) = 80·2^t · 3) V(t) = 20 + 8t · 4) P(t) = 90·2^t · 5) V(t) = 60 + 8t · 6) P(t) = 20·3^t
