The cost ,in dollars ,of renting a locker is a function of the time duration of the rental t in hours. the function c(t) outputs the cost c of a rental lasting t hours

how can the statement c(1.5)=9 be interpreted?

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
