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.

Sonali's father age is 5 year 3 times more then Sonali. find out Sonali age if her father age is 44.

enyata [817]

<h2><u>Given</u></h2>

Age of sonali father is year 3 times more then Sonali.

Age of sonali father is 44.

Age of sonali

<h2><u>Solution</u></h2>

Let assume the age of sonali be x

➡ Age of sonali = 3x + 5

➡ Age of sonali father = 44

<h3><u>According to the </u><u>question</u></h3>

<u> $\boxed{\sf \: \large\bf{\red{ \implies}} \: \Large\rm{\purple{ 3x + 5 = 44}}}$ </u>

Now , Solving this linear equation.

$\begin{cases}\large\bf{\orange{ \implies}} \: \Large\tt{\blue{ 3x + 5 = 44}} \\ \\\large\bf{\orange{ \implies}} \: \Large\tt{\blue{ 3x \: = \: 44 \: - \: 5}} \\ \\\large\bf{\orange{ \implies}} \: \Large\tt{\blue{ 3x \: = \:39 }} \\ \\\large\bf{\orange{ \implies}} \: \Large\tt{\blue{ x \: = \: \frac{39}{3} }} \\ \\ \large\bf{\orange{ \implies}} \: \Large\tt{\blue{ x \: = \: \frac{ \cancel{39}\rm \tiny{\red{ \: \: \small^{13} }}}{ \cancel{3}} }} \\ \\\large\bf{\orange{ \implies}} \: \Large\tt{\blue{ x \: = \: 13 }}\end{cases}$
