Is the data set approximately periodic? If so, what are its period and amplitude? not periodic

periodic with a period of 4 and an amplitude of about 20

periodic with a period of 4 and an amplitude of about 30

periodic with a period of 5 and an amplitude of about 25

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two
