Question

explain the meaning of each statement in this situation.
w(0) < w(30)
the temperature of the water after 10 minutes was 212 degrees fahrenheit.
the temperature of the water was the same after 10 minutes and after 12 minutes.
the temperature when the stove was turned on was lower than the temperature 30 minutes later.
the temperature after 15 minutes was higher than the temperature after 30 minutes.

Explanation:

In the context of a function \( W(t) \) where \( t \) represents time (in minutes) and \( W(t) \) represents the temperature of the water at time \( t \):

• \( W(0) \) means the temperature of the water at \( t = 0 \) (when the stove was turned on).
• \( W(30) \) means the temperature of the water at \( t=30 \) (30 minutes later).
• The inequality \( W(0)<W(30) \) is a comparison of these two temperature - values.

Answer:

The temperature when the stove was turned on was lower than the temperature 30 minutes later.
