two variable u and v are connected by the equation 1/u +1/v =1/f where f is a constant. given that f=10 cm and u decreases at a rate of 2 cm per second. calculate the rate of increases of v when u=40cm​

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.
