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.
option 4 .x<11 is the correct answer
2x - 2y = 2
2x - 2 x 0 = 2
2x - 0 = 2
2x = 2
x = 1
2x - 2y = 2
2 x 0 - 2y = 2
y = - 1
Answer:
6
Step-by-step explanation:
y + 1
= 7
y +
= 
y = 40/6 = 20/3 = 6
