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.

He equation 2x + 8 = 2(x + 5) has
Illusion [34]

Answer:

No solution.

Step-by-step explanation:

The equation 2x + 8 = 2(x + 5) has no solution  as we see if we simplify it:

2x + 8 = 2x + 10

2x - 2x = 10 -8

0 = 2 which is absurd.

If tsr = 84 what is the value of x? SQ bisects TSR RSQ= 3x-9
dsp73
We know that
 ∠ TSR = 84°

if SQ bisects ∠ <span>TSR
then 
</span>∠ RSQ = ∠ TSR/2
<span>so
</span>∠ RSQ = (1/2)*84°----- 42°
∠ RSQ = 3x-9
3x-9=42-------> 3x=42+9------> 3x=51-----> x=51/3-----> x=17°
<span>
the answer is
</span>x=17°<span>

</span>
