Step-by-step explanation:
Evaluating the limit of the function 9n - 3n / 2n.
First we factor out n from the numerator of the function to have
F(n) = n(9-3)/2n
Cancelling the variable n at the numerator with the one at the denominator we have:
Iim f(n) = 9-3/2
Iim f(n) = 6/2
Lim f(n) = 3
This shows that the limit of the function given is 3 no matter what the variable x is tending to.

Step-by-step explanation:
Let S be the sum of the times for all winning team.
Given:
leg 1. 32 minutes 56 seconds.
leg 2. 42 minutes 28 seconds.
leg 3. 34 minutes 34 seconds.
leg 4. 39 minutes 2 seconds
We need to find the total time to run all four legs of the marathon.
Solution:
Sum of the times for all winning team.
Substitute running times for all legs.
Now, we write the minutes and seconds separately.
Therefore, Total time taken by all four legs or .
