Dos ciclistas de ruta pasan simultáneamente, por dos posiciones A y B distantes entre sí 4 km, con velocidades Va = 40 km/h y Vb = 32 km/h si viajan en el mismo sentido. Hallar analíticamente y gráficamente: a. La posición del encuentro. B. El instante del encuentro.

Find the solution(s) to the system of equations. select all that apply y=x^2-1 y=2x-2

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
