John needs to divide the sample in half once the number of bacteria has reached 1000. How many hours after the initial time must
Reil [10]

Answer:

Option A

Step-by-step explanation:

The complete question is attached here

The rate of increase of bacterial population  be K

As we know

Y = Y_0 * e^{kT}

where Y is the final population. In this case it is 1000

K is the rate of increase of population i.e 3 times per hour

T is the time in hours

Y0 is the initial population = 5

Substituting the given values, we get -

1000 = 5 *e^{3*T}\\200 = e^{3*T}

Taking log on both sides, we get -

ln 200 = ln e^{3T}

2.718 * 2.301 = 3T

T = 2.084 hours

hence, option A is correct

Find the value of x that will make a||b help ?
nydimaria [60]

Answer:

x=30

Step-by-step explanation:

Find the value of x that will make A and B parallel

For A & B to be parallel, the interior angles must be supplementary, i.e.

4x+2x = 180

6x=180

x=30

When x=30, the interior angles are 120 and 60 which are supplementary.
