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

One month, Ruby worked 6 hours more than Isaac, and Svetlana worked 4 times as many hours as Ruby. Together they worked 126 hour

Paladinen [302]

Answer/Step-by-step explanation:

Let x hours be the number of hours Issac worked

x+6 hours be the number of hours Ruby worked

4(x+6) hours be the number of hours Svetlana worked.

x + x + 6 + 4(x+6) = 126

x + x + 6 + 4x +24 = 126

6x +30 = 126

6x = 96

x = 16

Therefore, Issac worked 16 hours.

Ruby worked 16+6 = 22 hours

Svetlana worked 22 × 4 = 88 hours.

Find the inverse of the following function.

Naddik [55]

For this case we must find the inverse of the following function:

$f (x) = 8 \sqrt {x}$

For this, we follow the steps below:

We change f (x) to y:

$y = 8 \sqrt {x}$

We exchange the variables:

$x = 8 \sqrt {y}$

We solve for y:

$8 \sqrt {y} = x$

We divide between 8 on both sides of the equation:

$\sqrt {y} = \frac {x} {8}$

We raise both sides of the equation to the square to remove the root:

$y = (\frac {x} {8}) ^ 2\\y = \frac {x ^ 2} {64}$

So, the inverse is: $f ^ {- 1} (x) = \frac {x ^ 2} {64}$
