Answer:
A ski lift is modeled by the function f(x) = (0.2)(–2x 3 + 23x 2 + 25x + 50), where x is the time in seconds. When it comes out of the first stop, it is now climbing toward its highest point from the ground. During which time interval will the ski lift reach a height over 50 feet above the ground?
Answer:
Sana takes 10 minutes longer than Ali in bathroom
Step-by-step explanation:
Given:
Ali Showers, brushes teeth 20 minutes
Thus, Ali takes 20 minutes time in bathroom
Sana Takes a bath, brushes teeth ½ hour
1 hour has 60 minutes
1/2 hour has 60/2=30 minutes
Thus, Sana takes 30 minutes time in bathroom.
Time, taken more by sana than Ali = 30 minutes - 20 minutes = 10 minutes
.
Thus, Sana takes 10 minutes longer than Ali in bathroom.
