<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>

Step-by-step explanation:
Answer:
1. 7
2. 97
Step-by-step explanation:
3 is the bottom length of the triangle and its the same for both sides so that leaves us with the square in the middle, since the bottom of the triangle is 3 and the top of the trapezoid is 10 we subtract 3 from 10 and get 7 and since a square has all identical sides we know the area of the square is 7 x 7 = 49 + 48 (which is the two triangles) = 97
