Answer:

a=-4000m+39000

Step-by-step explanation:

From the given table, we can see that the difference between any consecutive altitude is 4000 ft.

31000 - 35000 = -4000

27000- 31000 = -4000

23000-27000 = -4000

Hence, it represents an arithmetic sequence with a = 3500 and d = -4000

The general term of an arithmetic sequence is given by

a_n=a+(n-1)d\\\\a=35000+(m-1)(-4000)\\\\a=35000-4000m+4000\\\\a=-4000m+39000

Please help me solve this! I’ve been stuck for ages! Thankyou
polet [3.4K]

Answer:

y = sin(x- pi/2)

Step-by-step explanation:

Please see the attached image to see your graphs.

By simple inspection we can see that the sine is shifted pi/2 to the right.

We know this because sines are periodic functions with a period T = 2*pi

We can also see that the maximum point of the graph (y = 1) got shifted by a fourth of the period.

And finally, since we want to shift the graph to the right, we need to substract from the argument of the sine term.
