Answer:
Step-by-step explanation:
we know that
Hunter was biking for 2 hours 20 minutes and covered 35 miles
so
using proportion
Find out how long would it take him to cover 17 miles on this bike
Remember that
1 h=60 min
2 h 20 min=2(60)+20=140 min
Let
x -----> the time to cover 17 miles
therefore
Cosα=adjacent side divided by the hypotenuse
cosA=24/26=12/13
cosB=10/26=5/13
It is a function because here in case there is a value of y for x so it is a function.
