It gives you a few values. The values of f(t) and g(t) when time t=3, and
the values of the rates of change (first derivative) for both at the same time t=3.
f(3) = 8 unit
f ' (3) = 2 unit/s
g(3) = 3 unit
g ' (3) = 8 unit/s
--and also a value of the ratio of the two functions at t=3
If I know I will give it sorry
The question is probably incomplete. What i am assuming is that the person might ask for the previous ratio or the total number of pens and pencil in the drawer.
So if it is the previous ratio it obviously would be 47 - 5 : 17 -3 so 42 : 14 and in case he or she is asking for the total number of pens and pencils in the drawer before so they were 42 + 14 hence 56.
Answer:
Goodnight
Just put the first variable for each number and substitute to see if you could match for the answers as in (-6, 6, -4 and 4) ..Let me know if you got through to your answer !
Just type it into ur calculator
