Answer:
Option A.
Step-by-step explanation:
Based on the information provided on the question
the function used to model Tony's run is:
f(x) = -250*x + 5000
This means that after x = 20 minutes, Tony will arrive to the finish line
f(20) = -250*(20) + 5000 = -5000 + 5000 = 0
The function is always decreasing, because we are dealing with a line with negative slope.

Answer:
So, the arc length is
Step-by-step explanation:
We are given
diameter =36m
so, we can find radius
and angle as
Since, it is in degree
so, we can change it in radian
now, we can find arc length
now, we can plug values
