Answer:
[tex]H(d) = -9.5(d-1) + 100[/tex]
Step-by-step explanation:
Let [tex]d_n[/tex] denote the number of hits on day n, then:
[tex]d_1 = 100, d_3 = 81[/tex]
we can calculate that over the 2 days, the number of hits decreased by 19.
Assuming this is a linear equation and not an exponential decay line, then the series equation would be: [tex]d_n_+_1 = d_n - 9.5[/tex]
To write this as a linear equation, if H(d) is a function where d is the day starting from 1 and H(d) is the nubmer of hits on that day:
[tex]H(d) = -9.5(d-1) + 100[/tex]
