1. By definition, the amplitude of the sine function is:
[tex] y=asin(bx+c)+d [/tex]
[tex] Amplitude=|a| [/tex]
Then, the amplitude of the sine function is the absolute value of the coefficient [tex] a [/tex].
2. Based on this information, you have that the amplitude of the sine function given in the problem above is:
[tex] y = 50 sinx [/tex]
[tex] Amplitude=|50|=50
[/tex]
Therefore, the answer is: The amplitude of the function [tex] y = 50 sinx [/tex] is the absolute value of the coefficient: [tex] 50 [/tex]
