Can someone explain please and thank you!!

Asap describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x). f(x)=-5.8sin x. g(x)=sin x. a: vertical stretch by a factor of 5.8, reflection across y-axis. b: vertical stretch by a factor of 5.8,reflection across x-axis. c: horizontal stretch by a factor of 5.8, reflection across x-axis. d: horizontal stretch by a factor of 5.8 reflection across y-axis.

If sr is 4.5cm and tr is 3cm, what is the measure in degrees of angle s?

Which inequality is equivalent to -3x < -12? x < 4 , x < -4 , x > 4, x > -4
