Atelevision camera is positioned 4000 ft from the base of a rocket launching pad. the angle of elevation of the camera has to change at the correct rate in order to keep the rocket in sight. also, the mechanism for focusing the camera has to take into account the increasing distance from the camera to the rising rocket. let's assume the rocket rises vertically and its speed is 600 ft/s when it has risen 3000 ft. (round your answers to three decimal places.) how fast is the distance from the television camera to the rocket changing at that moment?

Ответ:
La densidad (más precisamente, la densidad de masa volumétrica; también conocida como masa específica), de una sustancia es su masa por unidad de volumen. El símbolo más utilizado para la densidad es la letra griega en minúsculas rho), aunque también se puede utilizar la letra latina D. Matemáticamente, la densidad se define como masa dividida por volumen: .m/V donde es la densidad, m es la masa y V es el volumen. En algunos casos (por ejemplo, en la industria del petróleo y el gas de los Estados Unidos), la densidad se define libremente como su peso por volumen unitario, aunque esto es científicamente inexacto – esta cantidad se llama más específicamente peso específico.
