Enter a function that models the given situation. Select the correct domain from the situation. Use set notation for the domain. A bicyclist travels at a constant speed of 18 miles per hour for a total of 27 minutes.

Explanation:

A bicyclist travels at a constant speed of 18 miles per hour for a total of 27 minutes

Using x to represent domain and

y to represent distance traveled

Domain (x) is number of hours used

Range (y) is distance traveled

speed = 18 miles per hour

time = 27minutes = 0.45hours

Since 60 mins makes 1hour

Therefore, 27mins will make x hour

X hour =27mins/60mins

X hour=0.45hours for 27mins

Distance = speed × time

Distance = 18 ×0.45= 8.1miles

Number of hours( x) used is from 0 to 0.45 hours

So domain which is the number of hours uses is 0 to 0.45hours

Range which is distance travelled is 0 to 8.1 miles

chavez's example shows that nonviolent protest can work well. it shows that one nonviolent man can stop a mob, which proves chavez's point and persuades people to protest nonviolently.
