Plz
what will the area of the wound be on day 8
on what day will the area of the wound be less one square millimeter
plz give me the right answer
i will give them 20 points

 1)Rewrite the table:
70,  49,  34.3,  24.01,  11.807

2) write the quotient of each number by the number before & notice the value:

49/70= 0.7
34.3/49 = 0.7
24.01/34.3 =0.7
16.0807/24.01 = 0.67 ≈0.7
You notice this is a geometric progression with r 0.7
The last term in a GP =ar^(n-1)
a=70; r= 0.7 n-1= number of terms (days -1)
For last term = 1 ==> then 1=70(0.7)^(n-1)
1/70 = (0.7)^(n-1)
log(1/70) =log[(0.7)^(n-1) ==> log1 - log 70 = (n-1) log(0.7) & you will find that it need 11.92 days to equal on & to be less than it will necessitate 12 Days

I’m pretty sure the slope would be 1 since the x and y values increase by 1
