Question

Jenny studied the characteristics of two species of bacteria. The number of bacteria of species A, A(t), after t hours is represented by the function, A(t) = 5 + (0.25t)3. The number of bacteria of species B, B(t), after t hours is represented by the function, B(t) = 2 + 8(1.06)t.

Which function describes the difference in the number of bacteria, N(t), of both the species after t hours?

A.

N(t) = 3 + (0.25t)3 + 8(1.06)t

B.

N(t) = 7 + (0.25t)3 + 8(1.06)t

C.

N(t) = 7 + (0.25t)3 – 8(1.06)t

D.

N(t) = 3 + (0.25t)3 – 8(1.06)t

1. Answer: D . Step-by-step explanation:

Given : Jenny studied the characteristics of two species of bacteria. The number of bacteria of species A, A(t), after t hours is represented by the function, The number of bacteria of species B, B(t), after t hours is represented by the function, Then, the difference in the number of bacteria, N(t), of both the species after t hours will be :- Hence, the correct answer should be : D .
