The table shows how the time it takes a train to travel between two cities depends on its average
speed.
Which rational function models the time, y, in
hours, that it takes the train to travel between the
two cities at an average speed of x miles per
hour?

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

-1/3(x+1)^5

i’m pretty sure this is correct
