The amount of bacteria in a petri dish doubles every 30 minutes. If you start with 2 bacteria, how many bacteria will you have after 5 hours?

ln (4) = ln (er

Step-by-step explanation

ln (4) = r · ln (e)

ln (4) = r

1.3863 ≈ r

Im not sure if im correct, But i do remember a question like this.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
