Can u send me a picture of the question instead please because i dont understand what ur trying to ask..
That is so confusing the way theyou word it sometimes is like what the...what?
Part A: After 9 days the radius of algae was approximately 12.81 mm. The reasonable domain to point is (0,9).
Part B: The 9 on the y-intercept represents the amount of algae the experiment started with.
Part C: (12.81-10.12)/7=0.38
No solution.
Step-by-step explanation:
1) Simplify 2 + 2 to 4.

2) Simplify 4 + 5 to 9.

3) Since 9 = 0 is false, these is no solution.
