Answer:
Equation of the line
Step-by-step explanation:
We need to construct an equation of the line that allows us to identify the given points and obtain a function in this regard.
These are the data we have
Y1 = 14500ft
Yf = 33000ft
Where the variables Y, represent the altitude.
We know that after 2 minutes the body has reached an altitude of
Y2 = 17000
On the other hand, the variable t represents time, so:
t0 = 0 min (the exact moment at which it is informed by the storm control tower)
t1 = 2 min.
The slope equation reads as follows:
(Y2-Y1) = m (t1-t0)
We replace
(17000-14500) = m (2-0)
m = 1250
That is to say that the equation of the line would be:
t = 1250 * x + t1
t = 1250 * x + 14500
If we wanted to know how long (t), it takes 3300ft to ascend, we simply replace it like this
33000 = 1250t + 14500
33000-14500 = 1250t
t = (33000-14500) / 1250
t = 14.8 minutes.
