This is a function where:
x - time in minutes;
y = f ( x ) - altitude of a plane in feet.
Max altitude = 35,000 feet
0.5 h + 2 h + 15 min = 30 min + 120 min + 15 min = 165 min
Domain:
x ∈ [ 0; 165 ]
Range:
y ∈ [ 0; 35,000 ]
I'm not really good at math but I would like to help.
If each call is $.08, then the card can call last for 250 minutes.
The call lasted 202 minutes. Divide 16.16 by .08.
<span>m∠DEF= 1/2(the measure of the arc DEF

Anything between -3≤x<3
Those integers can be -2,-1,0,1 or 2
