The quantities S(t), r(t), and h(t) are related by the equation S - What is true about the rates of change with respect to t of those quantities? Mark all that apply. we assume that S is constant, then (h?+2r) + rh -0. If dt dS h? dh If we assume that r is constant, then dt P+ n? dt None of the other options is correct. ds dt if we assume that h is constant, then at
