Answer:

Input value/x = 9

Step-by-step explanation:

The output value means y and the input value means x.

So they've told us the output value y = 4.5

Sub this into the function they gave us to get x

y=x/2

4.5=x/2

9=x

Simora [160]

Answer:  A. _3x2x2____

              7x2x2

Step-by-step explanation:

given fraction 12/28

here is the numerator = 12 = 2x2x3

here is the Denominator = 28 = 2x2x7

the prime factorization  simplest form  is _12_= _2x2x3______

                                                                        28           7x2x2

Two days after a biology experiment there was 49 million bacteria present. Four days after the experiment there was 600.25 milli
nataly862011 [7]

Answer:

y=Ae^(1.25t)

Step-by-step explanation:

From the expression  y=Ae^kt

After two days of the experiment, y = 49 million, t=2

After four days of the experiment, y= 600.25 million, t=4

A is the amount of bacteria present at time zero  and t is the time after the experiment (in days)

At t=2 and y =49

 49=Ae^2k…………….. (1)

At t=4 and y = 600.25

600.25=Ae^4k………… (2)

Divide equation (2) by equation (1)

600.25/49=(Ae^4k)/(Ae^2k )

12.25=e^2k

Take natural log of both sides

ln⁡(12.25) =2k

2.505⁡ =2k

k=1.25

The exponential equation that models this situation is y=Ae^(1.25t)
