Answer:
what is the equation?
Step-by-step explanation:
Answer:
2.2 hours
Step-by-step explanation:
The equation to graph is
4.5cos(4pi/25 x)+15
Find amplitude by subtracting min from max and dividing it by two. a=4.5
Find vertical shift k by finding the midline. Either add 4.5 to 10.5 or subtract 4.5 from 19.5. k = 15
The period is given to be 12.5. Use formula 2pi/b = period to find b. b = 4pi/25
Put the equation into graphing calculator and find what x equals when the graph is 17 (for the first time)
