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) 
Thus, the total number of cells in culture A at the end of one month will be: 
<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>
, where
Initial amount,
Final amount,
Rate of growth in decimal form and
Time duration.
Using the above formula, the number of cells after 30 days will be.....

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

Answer:
Step-by-step explanation:
The two dots on the bottom of this figure define the base of a triangle. If we now use a compass to draw the blue arcs on either side, as shown, the arcs will intersect at two points. A straight line drawn through these two points will be perpendicular to the base. The triangle will be isosceles and could be (but doesn't have to be) equilateral.
