7. You are at an altitude of 250 feet in a hot-air balloon. You turn the burner on high and rise at
a rate of 20 feet per minute for 5 minutes. Your altitude (h) after you have risen for (t) minutes is
given by the function h=250+20t.


(a) Make a table to show the altitude as a function of the number of minutes you have
traveled.


(b) Graph your data points-make sure to label the units on your axes.


(c) Does it make sense to connect the points on the graph? Explain.
