Question

1. Highlight the important information and circle the equation of the function.You are at an altitude of 250 feet in a hot-air balloon. You turn the burner on high and rise at a rate of20 feet per minute for 5 minutes. Your altitude h after you have risen for t minutes is given by thefunction h = 250 + 201.

Answer 1

So, the important information :

1. The first altitude which is = 250 feet

2. The rate of rise which is = 20 feet per minute

3. The equation of the altitude h after t minutes

h = 250 + 20 t

We can use this equation to find the altitude h after 5 minutes as following:

After 5 minutes, so t = 5

Substitute with t = 5 at the equation of the altitude h

So,

h = 250 + 20 * 5 = 250 + 100 = 350 feet
