Answer:
T represents the amount of time it will take him to travel 200 meters if he swims at 45 meters per minute.
Step-by-step explanation:
No it is not, in order for it to be it would have to have ... at the end meaning it continues, this stops and is rational
<span>The find step is to find C which is the vertical shift. This is the average between the maximum and minimum. So its 30+70=100/2= 50. the amplitude (A) take the average of the difference between max. temp. and min. value So 70-30= 40/2= 20, but it becomes -20 because the graph is shifted up 50 degrees and decreases to 30 at 4a.m. Then the period is 2pi/B which is 2pi/24, which equals pi/12. A=-20 B= pi/12 C=50</span>
