Step-by-step explanation:
On the graph, when y=0 find the x intercept.
The y=0 the x is at 1 and 3 so the first one is
(1,0)
and the second one is
(3,0)
Answer:
I attached a pic with the answers. Good luck! :)
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
Answer:
If they increase by the same amount each time.
So E.g. 1 3 5 7 9 (+ 2 each time)
BUT NOT e.g. 1 5 6 8 (+ random each time)
