A certain bacteria can divide every hour. Which of the following equations represents the number of cells, N, that is present after t hours? A
N(t)=2t

B
N(t)=2t

C
N(t)=2t

D
N(t)=t2

N(t) = N0/2^t

Step-by-step explanation:

Given that:

Number of cells present after t hours = N

Let initial number of cells = N0

Using the exponential decay relation:

N(t) = N0(1/2)^t

N(t) = N0/2^t

Hence, the number of cells N present after t hours is N(t) = N0/2^t.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
