8 (Picture) CONVERGENT AND DIVERGENT SERIES PLEASE HELP!!
djverab [1.8K]

Answer:

<em>The correct answer choice is:   B</em>

Step-by-step explanation:

<u>Culture A</u>

Initial number of cells = 1000

The number of cells is raised by 200 each day and every day thereafter.

So, the number of cells raised in one month(30 days) =200\times 30=6000

Thus, the total number of cells in culture A at the end of one month will be:  1000+6000=7000

<u>Culture B</u>

Initial number of cells = 1000

The number of cells is increased by 8% each day and every day thereafter.

<em>Formula for exponential growth is:</em>   A=P(1+r)^t, where P= Initial amount, A= Final amount, r= Rate of growth in decimal form and t= Time duration.

Using the above formula, the number of cells after 30 days will be.....

A= 1000(1+0.08)^3^0\\ \\ A=1000(1.08)^3^0= 10062.656...


That means, Culture B is more effective in promoting cell growth.
