Answer:

A. 13.

Step-by-step explanation:

x + 9 = 2(3x - 38)

X + 9 = 6X - 76

85 = 5x

x = 85/5

x =  17

So RS = 3(17) - 38

= 51 - 38

= 13

Jenny studied the characteristics of two species of bacteria. The number of bacteria of species A, A(t), after t hours is repres
fredd [130]

Answer: D . N(t) = 3 + (0.25t)^3 - 8(1.06)^t

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,

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

Then, the difference in the number of bacteria, N(t), of both the species after t hours will be :-

N(t)=A(t)-B(t)\\\\=5 + (0.25t)^3-(2 + 8(1.06)^t)\\\\=5 + (0.25t)^3-2-8(1.06)^t\\\\=5-2 +(0.25t)^3-8(1.06)^t\\\\=3+(0.25t)^3-8(1.06)^t

Hence, the correct answer should be : D . N(t) = 3 + (0.25t)^3 - 8(1.06)^t
