It depends on what you are asked to do. See explanation.
Step-by-step explanation:
The height, h metres, of a particle at time, t seconds is given by the function:
h=(14-t)(t-2).
This means that after a given time, we can use this function to find the height of the particle.
For instance after 3 seconds, the height of the particle will be:
This implies that:
So after 3 seconds the height of the particle is 11 meters.
Answer:
The answer is (C) .

Now, to find the equation for finding the length, in minutes, of a phone call that costs the same under either plan.
<em>Let the phone charges per minute be</em>
So, to get the equation of the phone plan A as the phone plan A charges $1.25 for the first minute and after that $0.15 for every minute:
Now, to get the equation of the phone plan B as given phone plan B charges a $0.90 connection fee and $0.20 per minute:
As, the phone call that costs the same under either plan.
Thus:
Therefore, the answer is (C) .
