<span>the answer:
the interpreted function is S(t) =9t-4, t = time in days, and S = number of people in thousands. The question consists of finding the value of S(4) and its meaning; for that, we replace the value of t by 4, in the equation S(t) = 9t -4, that is S(4) = 9*4-4=36-4=32, S(4) =32, in every four hours, 32 thousands people is attacked by swine flu. To find the value of t, when S(t)= 23, we have 9t-4 = 23, and then 9t= 23+4=27, t =27 / 9 = 3 so t = 3. S(t) = 23 does mean the value of time when 23 thousands of people is attacked by flu.</span>
Answer:
b. 40
Step-by-step explanation:
The value of x (exterior angle) is equal to half of the difference of given arcs
(100 - 20) ÷ 2 = 40
Answer:
The recursive formula for the given sequence
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given sequence is 8 , 16, 32, 64 ,.....
First term is a = 8
common ratio
and so on..
Given sequence of the common ratio 'r' is equal
The term of the sequence
This is recursive formula for the given sequence
<u><em>Verification</em></u>:-
put n=1 ⇒ t₁ = 8
put n=2 ⇒ t₂ = 16
put n=3 ⇒ t₃ = 32
put n=4 ⇒ t₄= 64
and so on..
The sequence 8 ,16 , 32 , 64 ....
