D. the total quantity of shoppers are needed for statistical information
We have been given that a particular type of cell increases by 75% in number every hour. We are asked to find the number of cells present at the end of 12 hours if there are initially 4 of these cells.
We will use exponential growth formula to solve our given problem.
, where,
y = Final amount,
a = Initial amount,
r = Growth rate in decimal form,
x = Time.

Upon substituting initial value
and
in above formula, we will get:





Therefore, there will be approximately 3300 cells at the end of 12 hours.
<h3>I'll teach you how to solve 4x^2-25<0</h3>
-------------------------------------------------
4x^2-25<0
Add 25 to both sides:
4x^2-25+25 < 0+25
Simplify:
4x^2 < 25
Divide both sides by 4:
4x^2/4 < 25/4
Simplify:
x^2 < 25/4
whole sqrt -25/4 < x < whole sqrt 25/4
whole sqrt 25/4= 5/2
-5/2 < x < 5/2
Your Answer Is -5/2 < x < 5/2

12s + 5 = 77
12s = 77 - 5 = 72
s = 72/12
s = 6 ...//
Ans = C ... 12x + 5 = 77 ...
The area of the parallelogram with a height of 13cm and base 20cm is 260cm².

How to find area of a parallelogram?</h3>
A parallelogram is simply a quadrilateral with two pairs of parallel sides.
The area of a parallelogram is expressed as;
A = base × height
Given the data in the diagram;
- Height of the parallelogram = 13cm
- Base of the parallelogram = 20cm
- Area of the parallelogram = ?
Plug the given values into the equation above and solve for A.
A = base × height
A = 20cm × 13cm
A = 260cm²
The area of the parallelogram with a height of 13cm and base 20cm is 260cm².
