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)
B cause it's true if you look at the graph
Answer:
I am not so sure but if I were to choose it went up from an 200% increase.
Step-by-step explanation:
The next 4 terms are 375, 75, 15 and 3
<h3>How to determine the next 4 terms?</h3>
The sequence is given as:
234375, 46875, 9375, 1875...
Notice that the current term of the sequence is 1/5 of the previous term.
So, the next four terms are:
Next 1 = 1/5 * 1875 = 375
Next 2 = 1/5 * 375 = 75
Next 3 = 1/5 * 75 = 15
Next 4 = 1/5 * 15 = 3
Hence, the next 4 terms are 375, 75, 15 and 3
