Answer:
-13/400
Step-by-step explanation:
The pertinent formula is
change in f(x) over [a, b] f(8) - f(0)
a. r. of change = --------------------------------------- = ----------------
change in x over [a, b] 8 - 0
Continuing these calculations, we get:
2(8) - 2 2(0) - 2 14/8 -2/8
(1/8) -------------- - (1/8) ------------- = ----------- - -----------
5(8) - 6 5(0) - 6 40 - 6 -6
7/4 1/4
This simplifies to average rate of change = ------- - --------
34 6
7 1
= ------------- - ---------- = -13/400
136 24
Answer:
The speed and time are directly proportional in that the higher the speed the lesser the time and vice versa.
The constant is the total distance which is 180 km
Step-by-step explanation:
Step one:
given data
The distance between the two cities is 180km
1.The distance was covered by a car at the rate of 50km/h
The time taken will be
velocity= distance/time
time= distance/velocity
time= 180/50
time= 3.6 hours
2.The distance was covered by a bus 45km/h
The time taken will be
velocity= distance/time
time= distance/velocity
time= 180/45
time= 4 hours
3.The distance was covered by a bicycle at 25km/h
The time taken will be
velocity= distance/time
time= distance/velocity
time= 180/25
time= 7.2 hours
