ayuda porfa, La impedancia eléctrica es la oposición al paso de la corriente eléctrica que circula a través de un conductor y se expresa utilizando números complejos. Si un gran circuito está formado por dos circuitos cuyas impedancias son z 1 = 3 - 4i ohmios y z 2 = 7 + 5i ohmios, ¿cuál es la impedancia total del gran circuito?

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
