Ahat [919]

Answer:

C. No. Vinay also multiplied the right-hand side of the equation by --5, which is incorrect.

Step-by-step explanation:

<u>Proper application of the property:</u>

- 5(m - 2) - 25 = -5m - 5(-2) - 25 = -5m + 10 - 25 = -5m - 15

A culture is grown with a population of 45 million cells. The cell population is found to double every hour. What will the popul

Alexandra [31]

45 million * $2^{4}$ = 45million * 16 = 720million

Or you can use
$y=Ae^{kt}$
A is equal to 45 million
To find the rate, k, we can plug in:
$90million=45million*e^{k*1}
$
$2=e^{k}$
$k=ln(2)$
$y=4.5*10^{7}*e^{t *ln2}$
Knowing that t = 4
$y = 4.5*10^{7}*e^{ln(2)*4}
$
$y = 720 million$
