The table below represents the distance of a car from its destination as a function of time: time distance (hours) (miles) x y 0 900 1 850 2 800 3 750 part a: what is the y-intercept of the function, and what does this tell you about the car? part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3, and tell what the average rate represents part c: what would be the domain of this function if the car traveled the same rate until it reached its destination?

A: The car started 900 miles away from its destination. Y intercept = 900

B: The average rate of change would be 50, meaning the car travels 50 miles every hour.

C: The domain of the function would be 0-18 since the car reaches its destination after 18 hours.

A: The car started 900 miles away from its destination. Y intercept = 90

B: The average rate of change would be 50, meaning the car travels 50 miles every hour.

C: The domain of the function would be 0-18 since the car reaches its destination after 18 hours.

You're Welcome :)

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
